Nice weather today with sunny skies...above normal temperatures and light winds.   However, this morning's satellite picture (below) shows the next low pressure area and frontal system in the Gulf of Alaska moving slowly southeastward.   This system will spread rain over the area Sunday with scattered showers and possible thunderstorms Monday.  Snow levels will drop to 5000 feet by Sunday afternoon and on Monday in some of the showers the snow levels will be 3000 to 3500 feet. 

Tuesday will be partly to mostly sunny.   Wednesday a weak low pressure area will move through Northern California (see map below) with light rain over the foothills and mountains and a few showers in the valley.  Snow levels will be 5000 feet north and 6000 feet south.  

Thursday through the weekend we will have a weak high pressure ridge along the coast.  This will push the jetstream northward.   The northstate will see partly to mostly sunny skies with a few clouds at times from storms moving by to our north.  Temperatures will be normal to a few degrees above normal.

  1. Hi Chris,

    Looking at the GFS longer range models, it certainly looks like the potential of multiple significant freeze events for the deciduous crops in your region, and especially for the Napa/Sonoma grapes. Might keep an eye on this possibility.


  2. Does the long range forcast show less gulf of alska cold fronts dropping south to our state and a return to a more traditional summer weather pattern?

  3. The current storm will bring a cold airmass...for this time of year...over the northstate. The forecast for the rest of the month shows a couple of weak fronts between now and the end of the month.
