There is a still a weak low pressure area over western Canada.  This system will cause a few afternoon clouds over the far north end of the state today and Sunday.   Temperatures will remain a few degrees below normal and winds will be light.

High pressure is slowly beginning to push northward along the west coast and by next weekend will be firmly established along the over the coast (see map below).   This means Monday through next weekend the inland areas of the north state will be mostl clear with warming temperatures.  Daytime temperatures will be above normal by Thursday and Friday.  Winds will be mostly light.

The cutoff low pressure area is off the coast and is drifting slowly eastward.  The low will move across the Pacific Northwest Thursday.   This system will bring some clouds a isolated showers and thunderstorms to the areas north of Redding today and Thursday.   The low will bring cooler air into Northern California with high temperatures today and Thursday 10 to 12 degrees below normal.  Gusty southwest to northwest winds will occur in the afternoon.

Friday through early next week another weaker cutoff will be over the Pacific Northwest and Canada (see map below).   This low will keep out temperatures a few degrees below normal through early next week.

It looks like by mid part  of next week the off shore high pressure area will be strong enough to warm things back to at least normal.

Sunny with a few high clouds today with near normal temperatures as high pressure remains along the west coast.  Tuesday things begin to change as a cutoff low from the Gulf of Alaska drops southward.   This low will be over the Pacific Northwest Thursday (see map below) and then move slowly eastward Friday and Saturday.   The main affect this low will  have is cool temperatures below normal Tuesday and keep them there through Saturday.   Most of Northern California will stay sunny.  However, Tuesday through Thursday there will a few clouds over the areas north of Redding with a chance of showers and thunderstorms.  Gusty southwest to northwest winds will occur in some areas Tuesday through Thursday.

High pressure will return to the west coast Sunday and should hold there through at least the middle of next week.  This means sunny skies and above normal temperatures for the north state.

High pressure is still along and over the west coast.  However, over the next several days the high will weaken as a low pressure area moves into Canada (see map below).   The main affects this low will have on Northern California is cooling and gusty winds.   Skies will remain mostly sunny with a few mid and high clouds.   Temperatures will be hot again today but should cool to near normal Thursday through Sunday.   Gusty northwest to north winds will continue through midday Sunday.

Next week things get interesting.  Another low pressure area will drop southward.  However,  the models take this further south through Northern Oregon.  Our temperatures will be normal or below and we will have gusty southwest to  northwest winds.  However, if the low moves a little further south the north state could see a few thunderstorms.

High pressure is along the coast.   Over the next few days this high will move a little to the west (see map below).   This morning's satellite picture (below) shows some sub tropical moisture has moved northward over the Sierras.  This moisture will fuel afternoon cumulus clouds over the mountains through Friday with isolated thunderstorms possible north and east of Redding.   Temperatures will continue 8 to 12 degrees above normal.

Saturday through next week the high will continue to dominate our weather.   We will see sunny skies with continued above normal temperatures.  Gusty north winds are expected Sunday through Tuesday.

Ref question about this years lightning...We have had an above normal occurrence of weak upper level low pressure areas this spring.   These might be weak but they bring cold air aloft in which coupled with the hotter air at the surface, due to the longer days really drops the stability more than we get with monsoonal moisture. 

High pressure is along the coast.  Today through Wednesday we will have sunny skies with some afternoon clouds over the mountains.  Temperatures will continue run 5 to 10 degrees above normal and winds will be light..

Thursday and early Friday an upper level low pressure trough will move through the Pacific Northwest and Canada (see map below).  This will weaken the off shore high pressure area.   Temperatures will cool back to  near normal on Thursday and Friday with a few clouds in the far end of the state.  Gusty north winds will start late Thursday and continue through Friday.

Saturday through early next week high pressure will rebuild along the coast.  The inland areas of the north state will be clear with above normal temperatures.  The gusty north winds will continue through midday Sunday.

The weak upper level low pressure area is still over the Southwestern U.S. and is moving slowly eastward.   Today and Sunday we will still have enough moisture and instability in the atmosphere to generate afternoon cumulus clouds over the mountains with isolated thunderstorms.  Temperatures today and Sunday will be 5 to 10 degrees above normal.

Monday and Tuesday high pressure will be along the coast.  The north state will be mostly clear with afternoon clouds over the mountains.  Temperatures will continue above normal and winds will be light.

Wednesday and Thursday a low pressure trough will move through the Pacific Northwest and western Canada (see map below).  The only affect this system will have on Northern California is a few clouds in the far north and temperatures will cool back to near normal.  

Friday through the weekend looks mostly clear with above normal temperatures.
