A low pressure trough and frontal system are approaching the coast.  Ahead of this system clouds are being pulled northward over Northern California.  This cloud mass will bring light showers or sprinkles to the area today.  The front and trough will move through later tonight and Sunday with more rain.  Snow levels will be 4000 to 5000 feet.  The rain will turn to showers Sunday afternoon and taper off during the evening.  Gusty south to southwest winds will occur in some areas later today.  

Monday another frontal system will brush the north end of the state.  This system will bring light rain or showers to the higher elevations with isolated light showers in the north end of the valley.  Snow levels will be 5000 feet. 

Skies will be clearing late Monday and early Tuesday and from late Tuesday through the weekend a high pressure ridge will be along the coast (see map below).  Skies will be clear with temperatures 10-15 degrees above normal Thursday through the weekend.  Light to moderate north winds will occur Tuesday through midday Friday.

The low pressure area is now moving inland over Southern California.  Today the north end of the state will be partly cloudy to cloudy with scattered showers.  Thursday we will see partly sunny skies with temperatures back to near normal. 

The next low pressure area will drop southward and remain off the coast.  It was earlier thought that this system would turn eastward and move over Northern California.  However, it now looks like it will drop south and move across Southern California late in the weekend. 

Friday through Sunday the north state should be mostly clear with a few clouds over the mountains.  Daytime temperatures will be a few degrees above normal.  Winds will be light. 

Sunday night another low pressure area will be dropping southward and the models are in pretty good agreement that this system will bring rain to the area Monday and Tuesday with some lingering showers Wednesday.  Snow levels will be 3000 to 3500 feet.

The low pressure area is now off the California coast and moving slowly southeastward.  The low will continue to send bands of clouds and rain across Northern California today and Tuesday.  Snow levels will be 2000 to 3000 feet and then rise a little on Tuesday.  Light to moderate southeast to southwest winds will occur.

Friday afternoon the next low pressure area will be dropping southward along the coast.  This system should move across Northern California late Saturday (see map below).  Rain is expected Friday afternoon and Saturday turning to showers Saturday evening.  The snow level will be near 4000 feet.  Gusty south winds are expected Friday afternoon and Saturday.

Sunday will be party cloud to partly sunny.  The next low pressure area will move through the area late Sunday and Monday and should bring more rain Sunday evening through Tuesday afternoon.  Snow levels will continue near 4000 feet.

Finally a return of winter weather.   This morning's satellite picture (below) shows a low pressure area off the coast.  When I wrote the last blog it was thought that this low would move sourtheastward.   However, it now looks like the low will remain off the coast through Sunday and then move slowly southward, crossing central and southern California late Tuesday and early Wednesday.  Because the low will stay off the coast and move slower...this means wetter weather for Northern California.  

Today through early Tuesday the low will send bands of clouds and rain across Northern California.  Snow levels will be 3000 to 3500 feet today and 2500 to 3000 feet Sunday and early Monday.  Gusty south to southwest winds will occur today.

Tuesday afternoon and Wednesday will be partly cloudy and cool with showers over the foothills and mountains.  Snow levels will be near 3000 feet.  

Thursday afternoon another low pressure area will approach the coast and will move across Central California Friday and Saturday.   This system will bring partly cloudy to cloudy skies to the north state will more rain and showers.

Skies clear late Sunday with mostly clear weather expected for the start of next week.

This morning's satellite picture (below) shows a frontal system now moving through Northern California.  The offshore frontal system is splitting apart and the southern portion will end up as a low pressure area off the Southern California coast (see map below).  This low will move slowly eastward and across the southern half of California Tuesday. 

Today the north state will be partly cloudy to cloudy with light rain or showers.  The snow level will be near 4000 feet.  Sunday and Monday we will see bands of clouds moving northward from the off shore low.  There will be isolated showers with the snow level remaining near 4000 feet.  

Tuesday through early Friday skies will be clear with temperatures a little above normal.  Gusty north winds will occur in some areas Tuesday.

Friday afternoon another low pressure area will drop southward along the Canadian coast and across Northern California.  This system will bring some clouds and scattered showers to our area late Friday through midday Sunday.

High pressure still along the coast.  Today and Thursday will be mostly sunny with daytime temperatures 10 to 15 degrees above normal.  Winds will be light. 

Friday a low pressure trough and frontal system will be approaching the coast.  This system will pass through Northern California Friday afternoon and Saturday.  Clouds will increase Friday with rain over the foothills and mountains Friday afternoon through Saturday.  There will scattered light showers in the valley.  Snow levels will drop to 3500 feet Saturday.  Skies will be clearing Sunday.  Gusty southwest winds will occur Friday afternoon and early Saturday.

There will be a low pressure trough approaching the coast Sunday.   However, it will split apart with a closed low pressure area being left off the coast (see map below).  This resulting split jetstream pattern will keep the north state dry as the stronger portion of the jetstream will be to our north.  

The off shore low will move slowly eastward and pass across Southern California about the mid part of next week.  Monday through Wednesday the north state will be partly sunny to partly cloudy.  The clouds will be coming from the off shore low.  Temperatures will be normal of a few degrees above.  Winds will be light.

HIgh pressure is back along the coast.  Today through Thursday we will see mostly clear skies with above normal temperatures.  Gusty north winds will continue through Tuesday.

Friday a low pressure trough will be approaching the coast (see map 1 below).  This system will move through Friday afternoon and Saturday with light showers over the foothills and mountains with the chance of an isolated shower in the valley.  The snow level will drop to 3500 to 4000 feet Saturday.  Gusty south to southwest winds will precede this storm.

The next low pressure trough will split apart and form a closed low pressure area well off the coast (see map 2 below).  This splitting of the jetstream will keep the north state dry with a few clouds from the off shore low.   The longer range models show the off shore low finally approaching the coast around the 11th or 12th of March.
