An upper-level ridge of high pressure is pushing desert air toward the Southern California and NW Mexico for the second day in a row, causing record-breaking temperatures across the region.
A record high temperature of 33.3 °C (92 °F) was registered in downtown Los Angeles on Thursday, November 23, 2017, breaking the previous record of 32.7 °C (91 °F) set in 1933 and making this Thanksgiving the hottest since record-keeping began in 1887.
However, downtown Los Angeles wasn't the warmest in the region today. As of 15:30 PST (23:30 UTC), the highest temperature in California was measured in Woodland Hills. With 35 °C (95 °F), this LA neighborhood broke the previous record of 33.3 °C (92 °F) set in 1995.
The second warmest temperature was registered at UCLA. Their station measured 34.4 °F (94 °F), breaking the previous record of 32.2 °C (90 °F) set in 1933.
On the same day, Camarillo recorded 33.8 °C (93 °F), breaking the old record of 31.1 °C (88 °F) set in 2015. The same temperature was measured at the Bob Hope Airport in Burbank, which broke the old record of 30 °C (86 °F) set in 1950.

Slightly cooler for Thanksgiving Day, with highs between 2 to 8 degrees cooler than today in many places, especially the beaches. It will remain very dry, so don't forget to hydrate through the day. #SoCal #CAwx #LAheat pic.twitter.com/ojao51AtvH— NWS Los Angeles (@NWSLosAngeles) November 23, 2017
The hot and dry conditions were caused by an upper-level ridge of high pressure hovering over the area, which brought desert air from the northeast to the Southern California coast, said Joe Sirard, a meteorologist with the National Weather Service in Oxnard.
Temperatures are expected to begin to fall on Friday, November 24.
