A day after record-setting heat baked parts of northern Los Angeles County, some slightly cooler temperatures could be on the way starting Wednesday.
“A persistent ridge of high pressure aloft over the region will result in very warm to hot temperatures from the valleys and inland through Tuesday with some cooling on Wednesday,” according to the National Weather Service.
An excessive heat warning was in effect in the Antelope Valley from 9 a.m. Tuesday until 10 p.m. Tuesday.
Lancaster reached a high temperature of 109 degrees Tuesday, breaking the 1945 record for the date of 107. In Palmdale, the high reached 107, breaking the record of 106 set in 1964. Sandberg reached a high of 98, breaking the 1991 record of 96 degrees, according to the NWS.
A less-severe excessive heat advisory was in effect until 10 p.m. Tuesday in the Santa Clarita Valley and Los Angeles County mountains, where temperatures also reached the triple digits.
Wednesday’s forecast called for highs from 95 to 103 in the Antelope Valley, the mid-90s in the Santa Clarita Valley and from the upper 80s to mid-90s in the lower elevations of the L.A. County mountains.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” forecasters advised. “Young children and pets should never be left unattended in vehicles under any circumstances.”
The NWS also issued its standard warnings against strenuous outdoor activity, and urged people to wear lightweight clothing and know the signs of heat exhaustion and heat stroke.
Forecasters said “slight cooling” is expected in the area by this weekend — but that another warming trend is on tap for next week.
