Temperatures inched upward again Wednesday as a mini heat wave settled over the region, with slight cooling on tap for Thursday and near-normal conditions anticipated by the weekend.
The heat pushed well into the 90s in many areas Wednesdays, which forecasters said would be the peak of the small heat wave.
National Weather Service forecasters said only slight cooling was anticipated for Thursday, but heat advisories that had been expected to continue until Thursday night in the Santa Monica Mountains Recreational area, Calabasas, Agoura Hills, San Fernando Valley, Santa Clarita Valley, San Gabriel Valley and Los Angeles County coastal area stretching to downtown Los Angeles were instead allowed to expire at 5 p.m. Wednesday.
“No heat advisories are in effect Thursday,” NWS officials confirmed.
“High pressure aloft will remain dominant over the region through Thursday, but does not look as potent as before,” according to the NWS, which predicted high temperatures of 85 to 95 degrees.
Onshore flow will increase Thursday and Friday, bringing a return of the marine layer by Friday and quickly bringing down temperatures to more normal levels. A “big cooling” is on tap for Saturday.
“This cooling will bring most coast/valley areas down to a few degrees below normal,” according to the NWS. “The strong onshore flow will bring gusty winds to the mountains, the Central Coast and the western Antelope Valley and foothills.”
Forecasters said a slight bump up in temperatures is anticipated Sunday.
In the San Bernardino and Riverside county areas, some relief from the heat is expected Thursday, but not much, with temperatures reaching the mid-90s in the valleys and triple digits in the Coachella Valley.
The high in the valleys and Inland Empire will be 96 Thursday, dropping a few degrees from highs in the area Wednesday.
Light winds from the southwest will be around 10 to 15 mph with gusts to 25 mph Thursday.
By Friday, temperatures are expected to drop to the high 80s. By Saturday, temperatures will be around 80.
The mountains will be warm and windy with highs between 82 to 92.
It will be sunny in the Coachella Valley with highs topping out at 107 Thursday. It will be sunny and hot on Friday with highs between 100 and 103.
Temperatures are expected to be in the triple digits in the Coachella Valley until Memorial Day.
