SOUTHERN CALIFORNIA GEOGRAPHICAL AREA COORDINATION CENTER

RIVERSIDE, CALIFORNIA

Weak surface high pressure in the Great Basin will bring north to east winds of 10 to 20 mph with gusts to 35 mph to the mountains and below the canyons and passes of Southern California through Saturday morning. High pressure aloft building into California from the Pacific will bring around 5 degrees of warming to the region each day through Friday. Temperatures will be near normal today, with mid 40s to mid 50s in the mountains and 60s to low 70s in the valleys. Temperatures will become around 10 degrees above normal Friday through this weekend when high pressure aloft will be directly overhead. Over the warmer valley locations, temperatures will reach into the low 80s this weekend. Minimum humidity will be between 20% and 40% today and then drop to 12% to 25% Thursday through this weekend. Temperatures will cool and humidity will increase early next week as the high pressure aloft weakens. Long range computer models suggest that the next chance for showers across the State will occur by the middle or end of next week.
