SOUTHERN CALIFORNIA GEOGRAPHICAL AREA COORDINATION CENTER

RIVERSIDE, CALIFORNIA

High pressure centered over the Desert Southwest will cause temperatures to remain 10 to 15 degrees above normal away from the coast today, with upper 60s and 70s across the mountains and 80s to low 90s in the valleys. Minimum humidity will be mainly in the teens away from the coastal areas today. Winds will be southwest to northwest 5 to 15 mph this afternoon. A couple of troughs will move inland across the Pacific Northwest bringing significant cooling and higher humidity to the region Tuesday and Wednesday. The marine layer will deepen and cover most coastal valley locations by Wednesday morning. Westerly winds of 20 to 30 mph with gusts to 50 mph will surface across the Owens Valley, Tehachapi Mountains, Antelope Valley, and Banning Pass Tuesday afternoon through Wednesday night. High pressure will build into California from the Pacific Ocean causing temperatures to warm and humidity to drop into the single digits and teens Thursday and Friday. There will be north winds of 20 to 30 mph with gusts to 50 mph across the south coast of Santa Barbara and across the Grapevine Wednesday night through Thursday morning. Offshore winds of 15 to 25 mph with gusts to 40 mph will surface across the mountains and below the canyons and passes of Southern California Thursday afternoon through Friday afternoon. Another trough will move into the West Coast bringing much cooler and more humid conditions to the region this weekend. Strong westerly winds will affect the desert passes by Sunday. END/Shameson
