A strong high pressure ridge will remain over the area through Friday afternoon.  During this time Northern California will see clear skies, with daytime temperatures 10 to 15 degrees above normal.  Winds will be light today and Thursday with increasing south winds Friday afternoon.

The weather feature to watch is the low pressure area off shore and southwest of California (see satellite picture below).  This low is moving northward and will turn more northeastward over the next 48 hours (see map below).  The low will move across Northern California Saturday.  Clouds will increase late Friday with showers and thunderstorms Friday night and Saturday.  Temperatures Saturday will be below normal.

Sunday there will be isolated showers and thunderstorms over the areas north of Redding with mostly sunny skies elsewhere.  Temperatures will continue below normal.  

Monday another weak upper low pressure area will be along the coast.  This system will bring isolated afternoon thunderstorms to the mountains.  Temperatures will be a few degrees below normal.

A strong high pressure area is over the western U.S. and will remain there through Thursday (see map below).  Northern California will be sunny with daytime temperatures 10 to 15 degrees above normal.  This means areas in the north end of the valley will see their first 100 degree reading of the year.  Winds will be light.

Note the weak low pressure area in the lower left corner of this morning's satellite picture (below).  This low will move slowly northward and will clip Northern California Saturday.  Friday temperatures will cool a few degrees and clouds will increase in the afternoon.  South winds will also increase in the afternoon.  Friday evening through Sunday morning we will see a few clouds with showers and possible thunderstorms mainly over the higher elevations.  Temperatures will be below normal Saturday and Sunday.  

Monday looks sunny and warmer and then there may be another weak upper level low pressure area along the coast by Tuesday, which could trigger more mountain thunderstorms.

The low pressure area that was off our coast has now moved northward and is off the Pacific Northwest coast.  However if you look at the satellite picture, below, you can see the westerly flow across the Pacific and around the bottom of the low is bringing quite a bit of cloudiness toward Northern California.  The low will lift slowly northeastward over the next 48 hours.  Today through Thursday afternoon Northern California will continue to have showers, with possible thunderstorms.  Snow levels will be near 6000 feet.  Gusty southwest winds will occur at times.  The showers will begin to decrease Thursday afternoon and end Thursday night.

Friday looks partly to mostly sunny with temperatures near normal.  Winds will be light. 

Saturday another, stronger, low pressure area will form off the coast (see map below).  This system will be along the coast Sunday and over the north state Monday.  Showers and thunderstorms will spread over the area Saturday afternoon and continue through  Monday afternoon.  Gusty south to southwest winds will occur Saturday and Sunday afternoons.

The weather the next 7 to 10 days won't be like you normally see in May.  This morning's satellite picture (below) shows a low pressure area approaching the coast. The low will reach the coast this evening.  Instead of continuing eastward the low will will move northward and be off the Pacific Northwest coast by Wednesday (see map below).  Showers and possible thunderstorms will spread over Northern California later today and periods of showers and thunderstorms will continue through Wednesday.  Locally heavy rain will occur in the stronger or larger showers.  Temperatures will be much below normal with snow possible above 6500 feet.  Gusty south to southwest winds will occur later today and Tuesday.  The showers will decrease Thursday and be mainly over foothills and mountains.  

Friday will be partly to mostly sunny with temperatures warmer but still a few degrees below normal.

Models are currently in good agreement that another...stronger...low pressure trough will reach coast Saturday afternoon and bring more rain and showers to the north state through early next week.

Wednesday the low will still be along the coast but will be weakening.  The north state will be partly cloudy with showers and thunderstorms over the foothills and mountains with the chance of showers in the valley.  Temperatures continue below normal with gusty south to southwest winds.  Thursday there will continue to be a few showers over the higher elevations with partly sunny skies in the valley.

Partly to mostly sunny Friday and little warmer...but temperatures will still be below normal.   Saturday afternoon another low pressure area reaches the coast and this will bring more showers to north state late Saturday through Monday.

A high pressure ridge is over California and is beginning to push or build northward.  This high pressure area will dominate our weather through the weekend (see map below).  Today and Tuesday Northern California will be partly to mostly sunny with a few clouds from fronts going by to our north.  Temperatures will be normal of slightly above.  Winds will be light.

Wednesday through the weekend the north state will be sunny.  Temperatures will be warming and will be 10 to 15 degrees above normal by the weekend.  Gusty north winds will occur Wednesday through Friday afternoon.

Early next week the low pressure area shown to our west on the map below will move close enough to the coast to bring a little cooling and maybe trigger some afternoon and evening mountain showers and thunderstorms.
