There will be some subtle changes in the weather over the next week.   The map below shows the high pressure ridge that has been over the Southwestern U.S. will push northward.   While the high will still be to our east it will allow a little warmer airmass to move over Northern California.  It will also push the low pressure area that has been over western Canada back to the west.

The next week the north state will be mostly clear.   Daytime temperatures will be near normal to a few degrees above normal and winds will be light.

The map below shows not much change expected.   The normal summertime high pressure area is over the Southwestern U.S.  However, the persistent low pressure area over western Canada has stopped it from pushing northward.   When this high pushes north during the summer is when we get our really hot weather.  

The next 7 days the inland areas of Northern California will be mostly sunny.   Temperatures will start off near normal and then rise to above normal by midweek and then cool to near normal by the weekend.  Winds will be light.

The overall weather pattern won't change much as the map below shows.   However, the high pressure over the southwestern U.S. will push a little northward which should bring temperatures back to normal or above the weekend.  Temperatures will cool a little early next week.  The next 7 to 10 days the inland areas of Northern California will be sunny with a few mid and high clouds at times.  Winds will be light.

The weather pattern we have been under and will be under for the next week is shown on the maps below.   High pressure is over the southwestern U.S. and is trying to push northward and link up with the high pressure area over Alaska.  This would form a fairly strong high pressure ridge along the west coast.  However, weak southwest to west flow across the Pacific is tending to split the ridge and suppress the southwestern high pressure area.  

This slightly increased southwest to west flow is common when we are in an El Nino pattern and we are currently in a weak El Nino.  

Bottom line the next week to 10 days we will have mostly clear skies with some afternoon cumulus over the mountains.  Temperatures today and Sunday will little above normal and then drop to a little below normal early next week and then warm up again by the end of the week.

High pressure continues to try and build northward along the the west coast.   However, the very weak cutoff low that is over Western Canada is holding it down.   This will slowly change and by this weekend the high will be along the coast (see map below). 

Today and Thursday the inland areas of Northern California will be mostly sunny with some afternoon cumulus clouds over the far north end of the state. Temperatures will be a few degrees below normal and winds will be light.  Saturday through most of next week we will have sunny skies with temperatures slightly above normal and light winds.

This morning's satellite picture (below) shows the very weak cutoff low is is off the Pacific Northwest and Canadian coasts.   Since this system is cutoff from the jetstream it's movement will be very slow.  The main this this low does is keep  the high pressure area off the coast from pushing northward and heating things up.

Today through Thursday most of the inland areas of the north state will be sunny with a few afternoon clouds over the northern mountains.  Temperatures will continue a few degrees below normal and winds will be light.

Friday through early next week the high will push northward and we will see sunny skies and above normal temperatures (sde map below).

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.
