This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.

The low pressure area is along the California coast and continues to drop southward.   This system has brought cooler air and gusty north winds to Northern California.  Moisture is limited but showers and possible thunderstorms will occur today over the higher elevations.   Sunday the low will be over Southern California.   The gusty north winds will continue with afternoon showers and thunderstorms over the Sierras from Plumas county southward.  

Monday through Wednesday high pressure will be back over our area.   The north winds will end Monday afternoon.  Temperatures will warming and by Wednesday will be 5 to 10 degrees above normal.  

Late Wednesday the high pressure area will begin to shift eastward as a low pressure trough approaches the coast.(see map below).  Thursday through the weekend the trough will be close enough to the coast to send weak frontal systems across Northern California.   During this time the north state will be partly cloudy to cloudy with light rain and showers over the mountains and a chance of showers in the north end of the valley.
