Celebrity Big Brother, also known as Big Brother: Celebrity Edition,[1] is a spin-off series of the American reality television series Big Brother. This season aired during the winter of the 2017–18 network television season on CBS and was the second U.S. Big Brother season to air outside the usual summer television season, the first being Big Brother 9 in 2008. Julie Chen returned as host, with Allison Grodner and Rich Meehan returning as executive producers. The season was produced by Fly on the Wall Entertainment in association with Endemol Shine North America. The season premiered on February 7, 2018.[2]
The promotional logo was released on December 20, 2017. The logo is similar to that used for Big Brother season 19, with the word "celebrity" added.[3] The first teaser was also released the same day.[4] In January 2018 official photos of the house and backyard were released through a press release and an Instagram livestream with Julie Chen.[5][6] On January 28, 2018, the official cast was announced during The 60th Annual Grammy Awards.
The season officially concluded on February 25, 2018 when Marissa Jaret Winokur beat Ross Mathews by a final jury vote of 6 to 3. Ross was also later named America's Favorite HouseGuest.

Background
After the first season of the British version of Big Brother proved to be a success in the ratings for Channel 4, the network collaborated with the BBC for the first British season of Celebrity Big Brother in aid of Comic Relief. The season ran for a condensed run of eight days and featured six British celebrities moving into the house used for the first British season.[7] Due to the success of the first celebrity edition, a second season was ordered and shown exclusively on Channel 4 in November 2002. The celebrity version took a two year break before returning for its third season in 2005, and became a regular staple alongside the regular British version. Starting with the third season, the show began to feature celebrities outside the United Kingdom alongside well known British celebrities. Many notable American celebrities have since taken part in the British version of Celebrity Big Brother.[8][9] American actor Gary Busey took part in the fourteenth season in the summer of 2014 and became the first American celebrity to win Celebrity Big Brother in the United Kingdom.[10]
An American version of Celebrity Big Brother has been speculated since 2002, along with a celebrity version of Survivor.[11] In an interview, Julie Chen and CBS CEO Leslie Moonves revealed talks of a celebrity edition of Big Brother as far back as Big Brother 2.[12] It was rumored that CBS was looking to air a celebrity edition in the fall after Big Brother 3 with radio personality Howard Stern speculated as a possible houseguest.[13] Chen revealed that Paris Hilton had agreed to do it and Roseanne Barr initially agreed to take part, but then backed out.[12] Barr would later take part in another celebrity spin-off of Big Brother called Big Brother: Celebrity Hijack in the United Kingdom in 2008, where she watched over a group of non-celebrity housemates for a day, set tasks and talked to them in the Diary Room.[14]
Julie Chen announced on September 7, 2017, during a live double eviction episode of Big Brother 19 that Celebrity Big Brother would air sometime during the winter, before the twentieth season of Big Brother in the summer of 2018. CBS later confirmed via a press release that Julie Chen would return to host the new season, and Allison Grodner and Rich Meehan will be executive producers. The season will be produced by Fly on the Wall Entertainment in association with Endemol Shine North America.[15]
On September 13, 2017, it was revealed by Chen that her husband, CBS chief executive Leslie Moonves, forced her to take a pay cut for the celebrity edition to happen. Moonves stated, "You shouldn't be expected to be paid as if it's a full series. It's a condensed version."[16]
Production
The format of the show remained similar to the American version of Big Brother. Competitions for Head of Household and Power of Veto had been confirmed to returned for this edition along with live evictions.[2] On December 1, 2017, CBS revealed that the series would premiere on February 7, 2018 and wrap on February 25, 2018.[17]
Series changes
Celebrity Big Brother was a condensed version of the game and would not last as long as a regular season of Big Brother, with episodes only shown over two weeks instead of three months.[16][18] Unlike the parent series Jury members were not sequestered separately and were allowed to return to the outside world as well as watch the show.[19][20] Beginning with an incident that led to a lawsuit in Big Brother 2 when HouseGuest Justin Sebik got drunk and threatened fellow HouseGuest Krista Stegall by holding a knife to her throat and stating "Wait, hang on, I’m going to slash your throat. Would you get mad if I killed you now?" there has been an alcohol restriction in the house.[21][22] The alcohol restriction was lifted for the Celebrity HouseGuests.[23][24] For the celebrity version of America's Favorite HouseGuest the term Favorite Celebrity HouseGuest was also being used interchangeably.[25][26] For the first time since the beginning of the U.S. series, five players were featured in the season's finale night versus the usual three.[27]
Broadcasts
The main television coverage of Celebrity Big Brother was screened on CBS during the winter of the 2017–18 network television season. CBS decided to schedule the spin-off during the February 2018 sweeps period to counterprogram NBC's coverage of the 2018 Winter Olympics.[15] Episodes aired on Sundays, Mondays, Wednesdays, and Fridays with two special episodes on Thursday, February 8 and Saturday, February 24. All episodes aired for one hour and aired from 8:00-9:00 p.m. EST; the Friday episodes and the season finale, however, ran for two hours each (from 8:00-10:00 p.m. EST).[28] The live Internet feeds returned for the American version of Celebrity Big Brother as part of CBS All Access.[15][12] Alongside the weekly shows on CBS, the companion series Big Brother: After Dark returned on Pop under the title Celebrity Big Brother: After Dark. The show provided live coverage nightly from inside the House.[15][29]
International broadcasts
The series was screened in Canada on Global in simulcast with CBS.[30]
The celebrity series is also the first American Big Brother season to be screened in Australia. [31]. The program aired on the Nine Network’s secondary channel; 9Go! from the 11th of February and air 5 times a week (Sundays to Thursdays) with Sunday and Thursday episodes set to air at 8:30pm and with other episodes set to air at 9:30pm.[32] Additionally, episodes were made available to Australian viewers on Nine’s streaming service 9Now the shortly after the American airing of the show.[33] However, low ratings saw the series bumped to late night timeslots on 9Go![34]

Notes
^Note 1 : Before the first HoH competition, the HouseGuests were instructed to stand on a number. The HouseGuest standing on the winning number would be awarded immunity that week. Omarosa was the winner and was immune from nominations for the week. Since she was immune, she became ineligible to compete in the HoH competition.
^Note 2 : Due to the Gift Bag twist, Keshia opened her bag to reveal she had the "Recast” Power, dethroning Shannon, who then became immune from nominations for the round.
^Note 3 : Mark, Metta, and Ross were the first three HouseGuests to fall in the HoH competition and were therefore put on slop for 48 hours.
^Note 4 : Viewers were able to choose which veto would be played for this eviction. The Diamond Veto allows the winner to save a nominee and choose their replacement. The VIP Veto gives the winner the option to use the veto once, twice, or not at all; if the winner chooses to use it they are able to save one of the nominees and then save the replacement nominee if the veto winner wishes to. The Spotlight Veto forces the winner to use the veto to save one of the nominees.[61] America chose the VIP Veto.
^Note 5 : There was a double eviction on Day 24. Following the first eviction, the remaining HouseGuests played a round worth of games — including HoH and Veto competitions and Nomination, Veto and Eviction ceremonies—during the remainder of the live show, culminating in a second eviction for the night.
^Note 6 : All four remaining houseguests competed in the final Head of Household competition. The new HoH then had to evict two houseguests, thus deciding who he or she will sit next to in the Final 2.
^Note 7 : During the finale, the jury members voted for which finalist should win Celebrity Big Brother.

Climate of Chicago
From Wikipedia, the free encyclopedia
Jump to navigation Jump to search
Chicago from Cermak-Chinatown station
The climate of Chicago is classified as humid continental (Köppen Dfa), with all four seasons distinctly represented: wet, cool springs; hot, and often humid, summers; pleasantly mild autumns; and cold winters. Annual precipitation in Chicago is average, and reaches its lowest points in the months of January and February, and peaks in the months of May and June. Chicago's weather is influenced during all four seasons by the nearby presence of Lake Michigan.

Official locations[edit]
The National Weather Service office in Chicago has one of the longest periods of official weather records, dating back to 1870, though all of the 1870 and 1871 weather records taken at 181 West Washington Street were lost in the Great Chicago Fire. As for the two major airports located in Chicago, Midway Airport began observations in 1928, and O'Hare Airport began observations in 1958. Both sites have served as official observation locations, with the latter being the current location where Chicago's official weather data is recorded. For Midway Airport, weather data prior to July 1, 1942 and after January 16, 1980 are not part of the official climate record of Chicago. All weather data taken at O'Hare from the beginning of observations in 1958 until January 17, 1980 are not part of the official climate record of Chicago.
Here is a list of official weather locations for the Chicago office:[1]

Winter[edit]
Winter in Chicago proves quite variable: Seasonal snowfall in the city has ranged from 9.8 inches (24.9 cm) (in 1920–21) up to 89.7 in (228 cm) (in 1978–79), and the average annual snowfall in Chicago is 36 inches (91 cm).[11] Most winters produce many snow falls during the season in light accumulations of around 2 in (5.1 cm). Cities on the other side of Lake Michigan usually receive more snow than Chicago because of the lake-effect snow that falls on these communities, even though northeasterly winds can sometimes bring lake-effect snow to Chicago area too. However, every three years or so during the winter Chicago experiences a heavier snowstorm that can produce over 10 in (25 cm) of snow over a 1- to 3-day period, a level of snowfall very often seen in cities on the "snowbelt" on other side of the lake such as Grand Rapids, Michigan, Kalamazoo, Michigan, and South Bend, Indiana.
Winter temperatures can vary tremendously within the span of one week. The daily average high temperature in January at O'Hare is 31.0 °F (−0.6 °C) with the average daily low of 16.5 °F (−8.6 °C) and the daily mean of 23.6 °F (−4.7 °C). Temperatures drop to or below 0 °F (−18 °C) on 5.5 nights annually at Midway and 8.2 nights at O'Hare and up to 10–14 nights in some far western and northern suburbs,[12] although subzero (°F) readings in the absence of snow cover are rare.[13] There have been streaks of multiple winter seasons without a single subzero reading, yet there have also been winters with 20 or more subzero readings. The highest temperature recorded during the meteorological winter months of December, January, and February is 75 °F (24 °C), set on February 27, 1976. The lowest temperature recorded during meteorological winter is −27 °F (−33 °C), set on January 20, 1985. In addition, the all time record low maximum temperature of −11 °F (−24 °C) was set on December 24, 1983, and tied on January 18, 1994.
The warming effect of Lake Michigan during the winter makes subzero temperatures somewhat less common on the lakefront than in the more inland parts of the city. Highs reach 50 °F (10 °C) an average of 8.8 days each winter from December to February at Midway.
Based on 30-year averages obtained from NOAA's National Climatic Data Center for the months of December, January and February, Weather Channel ranked Chicago the sixth-coldest major U.S. city as of 2014.[14]
Although it is extremely rare, temperatures during late winter (generally March 1–20) can reach up to and well over 80 °F (27 °C). In 2012, there were eight days in the month of March with temperatures 80 °F (27 °C)+ (with a ninth day occurring in many suburban areas) during the record-breaking March 2012 North American heat wave. The last couple of 80 °F (27 °C) days in this record-breaking stretch of warmth occurred after the vernal equinox.
Spring[edit]
Spring in Chicago is perhaps the city's wettest season: Winter conditions can persist well into April and even occasionally into May. Thunderstorms are especially prevalent in the spring time as the city's lakeside location makes it a center of conflicts between large volumes of warm and cold air, which can trigger a wide variety of severe weather.
On the other hand, large snowfalls can also occur in late March and in early April. For example, in 1970, over 10 in (25 cm) of snow fell in a storm that occurred on April 1–2.[15] Twelve years later, Opening Day for the Chicago White Sox was postponed due to another 9-inch (23 cm) snowfall that had occurred on April 5.[16] Even more extraordinary, over 18 in (46 cm) of snow fell on March 25–26, 1930, which remains one of the city's five biggest recorded snowstorms despite it occurring past the vernal equinox.[17] The average date for last measurable snowfall (≥0.1 in or 0.25 cm) is April 1.
Temperatures vary tremendously in the springtime; at 100 °F (38 °C), March is the month with the greatest span between the record high and low. At O'Hare, temperatures as low as 7 °F (−14 °C) and 31 °F (−1 °C) have been recorded as late as April 7 and May 21, respectively. Conversely, in official records, the earliest triple-digit (100 °F (38 °C)) high occurred on June 1, 1934, when official readings were taken closer to Lake Michigan. Though rare, triple-digit heat has occurred in late May at Midway Airport and in outlying suburban locations. Typically, the last freezing low of the season on average occurs on April 13 at Midway and ten days later at O'Hare. The highest temperature recorded during the meteorological spring months of March, April, and May is, officially, 98 °F (37 °C) on May 31, 1934, when weather records were still taken near Lake Michigan. The lowest temperature recorded in meteorological spring is −12 °F (−24 °C), set on March 4, 1873.
During the springtime, the effects of Lake Michigan are most prevalent. During this season, the lake is still quite cold, as the effects of much warmer temperatures are slow to affect the large body of water of Lake Michigan. It is common for Lake Michigan shoreline and water temperatures to remain in the 40s even into May. If the winds blow from the east, or from Lake Michigan into the city, a wide discrepancy in temperatures in a matter of miles can be found, especially on particularly warm days. It is not uncommon for high temperatures to be officially recorded in the 80s and occasionally 90s at O'Hare, Midway, and in suburban locations but to have temperatures be only in the 40s or 50s along the immediate lakeshore.
Summer[edit]
On a typical summer day, humidity is usually moderately high, and temperatures ordinarily reach anywhere between 78 and 92 °F (26 and 33 °C). Overnight temperatures in summer usually drop to around 65–70 °F (18–21 °C), although even in July and August there can be several nights where the temperature drops below 60 °F (16 °C), particularly during the cooler summers. Conversely, on the other extreme, temperatures can on a rare basis remain above 80 °F (27 °C) overnight, though this level of overnight warmth is generally limited to the city proper with its urban heat island effects along with Lake Michigan nearby. On such warm nights, especially during strong heat waves, most suburban locations drop down to between 75 and 79 °F (24 and 26 °C) but quickly rebound in the early morning hours. During such strong heat waves, the outlying suburban areas can record temperatures more than 5 °F (3 °C) above city and lakeshore locations.
A perfect example of such an occurrence happening, although considered "unofficial", occurred during the Dust Bowl years. Midway Airport recorded a record eight consecutive 100 °F-plus days in July 1936. In that heat wave, temperatures at the lake remained in the middle and upper 90s Fahrenheit (middle 30s Celsius), whereas Midway Airport recorded temperatures over 100 °F (38 °C) for nearly two weeks, peaking at 107 °F (42 °C) on July 11. The official record high for Chicago for July 11 is also from 1936—but is recorded as just 97 °F (36 °C). Further west in what would today be the near and far suburbs (e.g. DuPage County and westward), temperatures reached a blistering 110 °F (43 °C) or still higher at points during this massive heat wave. These extreme temperatures are not shown in the official records because daily weather observations were taken at the University of Chicago until 1942. The University of Chicago is close to the lake, which can and does reduce temperatures in the immediate shoreline area in the summer.
The highest temperature recorded in Chicago during the meteorological summer months of June, July, and August, which is also additionally the all-time record high in the city, is 105 °F (41 °C), set on July 24, 1934, though at Midway Airport, a future observation site, the temperature reached 109 °F (43 °C). The lowest temperature recorded in the meteorological summer months is 35 °F (2 °C), set on June 4, 1945. In addition, the all time record high minimum temperature of 85 °F (29 °C) was set on July 29, 1916.
Chicago's yearly precipitation comes in at an average of about 36 inches (910 mm), but during the summer, rain arises from short-lived hit-or-miss rain rather than actual prolonged rainfalls, and thunderstorms also occur with regularity at night. In a normal summer, temperatures exceed 90 °F (32 °C) on 23 days. Summer is both the rainiest and sunniest season here;[18] only the three months of June through August experience more than 65% of possible sunshine.[9]
In July 2012 Chicago reached and exceeded 100 °F (38 °C) for three consecutive days at O'Hare Airport with highs reaching 103 °F (39 °C) in the city and many suburban areas recording temperatures between 105 and 110 °F (41 and 43 °C). It was the first time in 65 years that Chicago had ever seen a triad of 100 °F (38 °C) days.[19] Chicago nearly recorded a fourth consecutive 100 °F (38 °C) day, but the temperature reached 98 degrees at O'Hare in late morning before a cold front came through the area and cooled temperatures off slightly in the city area, holding in the lower 90s. The effects of the cold front did not affect many suburban areas, as temperatures reached or exceeded 100 °F (38 °C) for a fourth consecutive day throughout much of the region.
During the summer, Lake Michigan continues to have an effect on Chicago weather, but it is not as common or as strong as it is during the spring months. On very hot days, temperatures can still be cooler along the immediate shoreline and slightly inland of the lake if winds blow from the east. Temperatures can be held in the 70s or 80s in these areas while outlying and suburban areas temperatures are rising well into the 90s. Temperatures can also reach extreme levels of heat on the immediate shoreline, such as when the air temperature reached 105 °F (41 °C) at Northerly Island during the aforementioned July 2012 heat wave.
Autumn[edit]
The extreme heat that Chicago is capable of experiencing during the height of the summer season can persist into the autumn season. Temperatures have reached 100 °F (38 °C) as late as September 7 (with 99 °F (37 °C) occurring as late as September 29), and temperatures have reached 90 °F (32 °C) as late as October 6, which occurred in 1963, with a temperature of 94 °F (34 °C) on that day. Conversely, temperatures have dropped below freezing overnight as early as September 23, and temperatures below 0 °F (−18 °C) have arrived as early as November 23. Although extremely rare, temperatures at or above 70 °F (21 °C) have been recorded into early December, most recently in 2012 when 70 °F (21 °C) was recorded on December 3, some surrounding areas reaching temperatures as high as 72 °F (22 °C) to 75 °F (24 °C).
Autumn, in some ways, is a calmer season than any of the other three in Chicago. This does not mean that wild weather can't happen. The first freeze of the season on average occurs on October 24 at Midway and 11 days earlier at O'Hare. In most years, a period of warm weather, known as an Indian summer, occurs well after the autumnal equinox has occurred. In these so-called Indian summers, unusually warm weather can persist for several days well into October, and in particularly warm autumns, into November. For example, during the 2005 American League Division Series, for both home games between the Chicago White Sox and the Boston Red Sox, temperatures soared to near 90 °F (32 °C), despite the fact that it was already well into October. On top of that, during the same warm stretch in October 2005, for two consecutive days the overnight temperature failed to drop below 70 °F (21 °C), a rare occurrence for Chicago in October.
The highest temperature recorded during the meteorological autumn months of September, October, and November is 101 °F (38 °C), set on back to back days, September 1–2, 1953, closely followed by Chicago's latest 100 °F (38 °C) on September 7, 1960. The lowest temperature recorded during the meteorological autumn months is −2 °F (−19 °C), set on November 29, 1872 and tied on November 24, 1950.
Autumn can bring heavy rain showers, some of which are capable of producing serious flooding. As the winter solstice nears, the threat of a major winter or snowstorm grows, and there have been major winter storms around the Thanksgiving holiday, causing major delays at the city's two major airports. The first measurable ≥0.1 in (0.25 cm) snow on average falls on November 19. However, in the 2012–13 winter season, the first measurable snow did not fall until December 20, 2012, eclipsing the previous record of December 17, 1899. The 2012–13 autumn/winter season would fail to produce a daily maximum temperature below freezing 32 °F (0 °C) until January 1, 2013, the first such time that has happened in Chicago weather records. The entire calendar year of 2012 did not record a temperature lower than 5 °F (−15 °C). The largest snowstorm before the winter solstice dropped 14.8 inches (380 mm) at Midway Airport in December 1929.
During the autumn, the effects of Lake Michigan are usually reversed from the spring or summer, particularly in the late autumn. Temperatures near the immediate lakeshore can be a few degrees warmer than in outlying areas, especially during nighttime due to the delayed effects of cooler temperatures on the large body of water. It is rare, though possible, during the Indian summer when unusually warm temperatures are occurring in the inland areas of the city and suburbs for temperatures to be somewhat cooler along the lake as often happens during the spring season.
Extremes[edit]
The highest temperature ever recorded in the Chicago city limits is an unofficial 109 °F (43 °C) on July 24, 1934, at Midway Airport. The official reading of 105 °F (41 °C) for that day was taken at the University of Chicago campus near the shoreline off Lake Michigan. The 105° high that day is the highest official temperature ever recorded in the city.[20] On July 29, 1916, the low temperature sank to only 85 °F (29 °C). Many suburban locations have all-time records that have surpassed 110 °F (43 °C).
Readings near the lake can be several degrees cooler than inland locations if lake breezes are present, which suggests that the higher unofficial reading may also be accurate. During the Chicago Heat Wave of 1995, official temperatures reached 104 °F (40 °C) at O'Hare Airport and 106 °F (41 °C) at Midway, but high humidity pushed the heat index to 15–20 °F (8–11 °C) above actual air temperatures, resulting in heat indexes well over 120 °F (49 °C). The coldest temperature ever recorded in Chicago city limits is −27 °F (−33 °C) at O'Hare on January 20, 1985, though unofficial temperatures as low as −33 °F (−36 °C) have been recorded at Chicago Aurora Airport in far western suburbs and in the rural areas to the west of Chicago.[21] On December 24, 1983, and January 18, 1994, the high temperature reached only −11 °F (−24 °C).
The greatest 24-hour precipitation was 6.86 in (174.2 mm) at O'Hare on July 23, 2011, while the heaviest 24-hour snowfall was 18.6 in (47.2 cm), again at O'Hare, on January 2, 1999. Daily snow depth has amassed as high as 29 in (74 cm) on January 14, 1979; as of 2018, January 1979 alone holds 8 of the top 10 daily snow-depth measurements.
Windy City[edit]
Chicago is known as the Windy City. The "Windy City" moniker did not originally refer to Chicago's climate[citation needed]. It is believed to have been created by a New York newspaper writer deriding Chicagoans' bluster as they promoted their city as the site of the 1893 Columbian Exposition. In terms of climate, Chicago is slightly windier than the average American city. Average wind speeds range from 8 miles per hour (13 km/h) in late summer to 12 miles per hour (19 km/h) in spring months.
Lake breeze[edit]
Further information: Lake-effect snow
Chicago can be cooler and moister than other parts of Illinois because of its proximity to the relatively cooler waters of Lake Michigan, effects which are most pronounced during spring and early summer. A frequent lakeshore breeze pushes much cooler, moister air into Chicago than the usual hot air of the Plains States (usually a moist air mass depending on upper level circulation), but the effect can be so localized that only the immediate waterfront neighborhoods (both north and southside lake adjacent communities) are cooler than inland parts of the city. South, west and southwestern suburbs can be more than 20 °F (11 °C) warmer than the lakefront at some times of year.[citation needed] The lake breeze also has other effects, including dense fog spilling into the city. Because of the closed-loop circulation pattern with a lake breeze that moves back and forth across the city, it is thought to significantly increase low-level ozone counts.[22] Differing wind direction on either side of the thermal dividing line allows for sharp updrafts under certain conditions, favorable to thunderstorm development. Offshore or land breezes shutdown the lake breeze and can have the opposite effect, with over lake convection occurring, usually in mid- to late summer and autumn. As a general rule, the opposite trend occurs during the winter—winter temperatures are warmer along the lakeshore and downtown than inland.
