Temperatures will climb into the 80s in some communities Wednesday and remain above normal for several days, forecasters said.
No heat records are expected, and temperatures, being below the 90s, will not quite add up to a heat wave, said National Weather Service meteorologist Dave Bruno. But it will be warm. Woodland Hills, for example, is forecast to have a high of 86 degrees Fahrenheit Wednesday, climbing to 88 Thursday on what will be the week’s hottest day. By Thursday, temperatures will be 10-20 degrees above normal, according to an NWS statement.
The lowest highs in the area Wednesday will be 73, which is what’s forecast in Lancaster.
The heat results from a strong upper-level high pressure system, said Bruno, adding that the system is pushing down the air, and when air sinks, it becomes warmer. But no warnings of unusual wildfire risks were issued, even though some wind was blowing and humidity levels were relatively low, falling to the teens in the mountains.
The NWS forecast partly cloudy skies in Los Angeles County Wednesday and highs of 73 in Lancaster; 74 in Palmdale and Avalon; 76 on Mount Wilson; 79 at LAX; 81 in San Gabriel; 82 in Saugus; 83 in Long Beach and Downtown L.A.; 84 in Pasadena and Burbank; and 86 in Woodland Hills. Thursday’s highs will be up to 4 degrees higher in some communities, then remain in the 70s and 80s for at least six days.
Sunny skies were forecast in Orange County, along with highs of 68 in Newport Beach; 69 in Laguna Beach; 70 in San Clemente; 80 in Mission Viejo; 81 in Anaheim and Irvine; 82 in Fullerton; and 85 in Yorba Linda.
Thursday’s Orange County temperatures will be the same as Wednesday’s in some communities and a little higher in others, including in Yorba Linda, where a high of 87 is expected. Temperatures in the 80s and 70s will persist in Orange County through Tuesday.
