An upper level ridge of high pressure will bring continued very high temperatures to Southwest California through the weekend. The hottest and most dangerous conditions will be across the Antelope Valley, and many interior locations including inland valleys and the lower mountain elevations. During this time, overnight lows will also remain warm (in the 70s) across portions of the valleys, mountains, and Antelope Valley, adding to the heat stress. The hot conditions will result in an increased risk of heat-related illnesses, especially for the homeless, the elderly, infants, outdoor workers and those participating in outdoor activities. The combination of hot temperatures, low humidities (including poor overnight recoveries), and very dry fuels will bring a prolonged duration of elevated fire danger to Southwest California, especially interior sections. In addition, gusty winds through the L.A. County Mountains into the Antelope Valley each afternoon and evening may bring brief critical fire weather conditions to those areas.
