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.

Mostly sunny today with afternoon temperatures 5 to 10 degrees above normal.  Gusty north winds will occur in some areas.  

Things start to change Thursday.  The low pressure area and frontal system shown on this morning's satellite picture (below) will be slowly moving toward the coast.  Clouds will be increasing and temperatures cooling.  The front will bring rain to Northern California Friday with scattered showers Saturday.  Snow levels will lower to 3000 feet north and 4000 feet south by Friday afternoon.  Gusty south winds will precede the front.

The showers end by late Saturday afternoon and there will be some clearing.   However, the next storm system will spread light rain over the area Sunday.  Snow levels with this system will be 2000 feet north and 3000 feet south.  However, cold trapped air in the canyons and valleya will lower the snow level to  near 1000 feet from Redding northward. 

Skies clear out Monday afternoon but another storm should reach the coast Wednesday.

  1. A little but southern branch is pretty strong on this one. Sunday system looks more split flow but models are not in good agreement on the split.
