RIVERSIDE, CALIFORNIA

A weak trough moving inland over the West Coast will bring near normal temperatures to the region through Tuesday, with upper 50s and 60s in the mountains and 70s to low 80s in the valleys. Minimum humidity will be mainly between 20% to 40% today and then drop to 15% to 30% Tuesday. South to west winds of 10 to 20 mph with gusts to 35 mph will surface across the desert passes this afternoon through tonight. The back side of the trough will bring northerly winds of 10 to 20 mph with gusts to 35 mph to the south coast of Santa Barbara and the Grapevine Tuesday night. A brief ridge of high pressure pushing in from the south will cause temperatures to warm to 5 to 10 degrees above normal and humidity to drop to 12% to 25% Wednesday and Thursday. Winds will be light Wednesday and Thursday. Another Pacific trough will move into the West Coast bringing a cooling trend and an increase in humidity to the region Friday through this weekend. This trough may be strong enough to bring scattered showers with light rainfall totals from a Monterey/Fresno County line northward Saturday morning. There will be gusty south to west winds across the mountain ridges and desert passes Friday afternoon through Saturday evening. END/Shameson
