Temperatures surpassed 100 degrees in the San Fernando, San Gabriel and Santa Clarita valleys today because of surface high pressure building over the Great Basin that brought a period of weak offshore flow, according to the National Weather Service.
The Studio City Weather Station recorded a high of 107.6 degrees in Studio City—just missing the 108-degree high set in 1980.
Most of the local area schools are keeping the children indoors during lunch, P.E. classes and recess, and the Studio City Library as well as banks and restaurants have served as cooling-off centers in the extreme heat.
According to local Studio City weatherman Grant Miles, who has his own weather station, temperatures on Tuesday in Studio City could hit 105 degrees—and that would break the previous high of 102 degrees set in 1958.
The highs were 109 in Saugus, 107 in Chatsworth and Woodland Hills, 106 in Northridge and Pasadena, 105 in Burbank and Van Nuys, 103 in Pomona, 102 in San Gabriel and 100 in Acton, according to the National Weather Service.
A record for this date was set in Lancaster, where the high of 99 erased the previous record of 98 set in 1980.
A red flag warning denoting a high risk of wildfire will be in effect until 6 p.m. Tuesday in the Santa Clarita Valley and the San Gabriel Mountains in Los Angeles and Ventura counties. The mountain regions include the Angeles National Forest in Los Angeles County and Ventura County's Los Padres National Forest.
Conditions will not be as hot or dry Tuesday thanks to an onshore flow that will bring stronger onshore winds to the region, especially across the mountains and Santa Clarita Valley, where gusts between 25 and 30 mph can be expected, according to the National Weather Service.
The National Weather Service forecast calls for highs Tuesday of 104 in Woodland Hills, 102 in Pasadena and Saugus, 99 in Burbank and San Gabriel, 97 in Lancaster and Palmdale, 95 in Long Beach, 93 in downtown Los Angeles and 85 at Los Angeles International Airport.
