For the first time this week, no wildfire warnings, wind advisories or high-heat warnings were in force anywhere in the Southland today, and a slow cooling trend got underway, but temperatures remained more than 10 degrees above normal in several communities.

All the special weather advisories that the National Weather Advisory had issued for the region were allowed to expire Wednesday. The last one was an excessive heat warning, which had been due to expire Tuesday but was extended to 8 p.m. Wednesday. However, even though no heat warning is in effect, a ridge of high pressure aloft is keeping temperatures well above normal, forecasters said.

The NWS forecast sunny skies today and highs of 81 on Mount Wilson; 82 at LAX; 83 in Avalon; 86 in Palmdale and Lancaster; 87 in Long Beach; 90 in Downtown L.A.; 91 in San Gabriel; 92 in Burbank; 93 in Pasadena and Saugus; and 96 in Woodland Hills. NWS meteorologist Rich Theompson said the normal temperature for this time of the year is 77 in Downtown, 13 degrees lower than today; 78 in Burbank, or 14 degrees less than today; and around 78 in Woodland Hills, or 18 degrees below today’s high.

L.A. County temperatures will be slightly lower Friday, rise slightly Saturday, then resume slowly falling on Sunday. By Wednesday, highs in Woodland Hills will be 18 degrees lower than today, and 14 degrees lower in Downtown L.A.

Sunny skies were also forecast in Orange County today, along with highs of 76 in San Clemente; 77 in Newport Beach; 80 in San Clemente; 88 in Mission Viejo; 89 in Irvine and Anaheim; and 91 in Fullerton and Yorba Linda. Temperatures will dip slightly Friday, rise slightly Saturday, then dip again Sunday before taking a sharper fall Monday. By next Wednesday, the high in Yorba Linda will be 76 — around 15 degrees less than today — and 68 in Laguna Beach, or 9 degrees less than today.

It will be 92 in Perris; 93 in Riverside; and 99 in Palm Desert.

Today’s highs include 89 in Rancho Cucamonga; 90 in Ontario; and 93 in Redlands and San Bernardino;

By Monday, the region’s heat wave will be over, forecasters said.
