RIVERSIDE, CALIFORNIA

A weak ridge of high pressure over the region will cause temperatures to be 5 to 10 degrees above normal through Thursday, with mid 50s to mid 60s across the mountains and upper 60s and 70s in the valleys.  Minimum humidity will be mainly between 20% and 40% through Thursday.  Winds will be light through Thursday.  A Pacific storm will bring scattered showers to the region Thursday night through Friday night, with most locations expected to receive less than a quarter inch of rainfall.  However, the Sierra and its surrounding foothills will receive between 1 and 2 inches of rainfall.  The snow level will drop down to around 4,000 feet by Friday night.  Westerly winds of 20 to 30 mph with gusts to 50 mph will surface across the wind prone mountains and deserts Thursday night through Friday night.  Temperatures will drop to between 5 and 10 degrees below normal on Friday.  A weak ridge of high pressure will move across the region from the Pacific Ocean bringing a little warmer and drier conditions this weekend.  North winds of 20 to 30 mph with gusts to 50 mph will surface across much of Santa Barbara County and the Grapevine Saturday night.  Another Pacific storm may bring more scattered showers with light rainfall totals to the area early next week. 

 

There will be little or no fire activity across the region through the forecast period.
