This morning's satellite picture (below) shows a low pressure area dropping southward just off the Oregon coast.  This low will continue southward and will end up over Southern California by Sunday afternoon.  The low will bring clouds to Northern California today with a few light showers in the mountains later today and early Sunday.  Skies will be clear over most of the north state by Sunday morning or early afternoon.  Temperatures today will be near normal and a little below normal on Sunday.  Gusty north winds will move into our area today and continue through Sunday.

Monday through Wednesday will be sunny with above normal  temperatures.  Gusty north winds will end early Wednesday.

Thursday a low pressure trough will be approaching the coast (see map below).  Clouds will increase Thursday afternoon.  This system will bring light rain to the foothills and mountains, Friday through midday Saturday with a few light showers possible in the valley.  Snow levels will start out high but drop to 4000 feet by Friday afternoon and then a little lower on Saturday.   Gusty southwest winds will occur late Thursday with the winds shifting to the north by Saturday.

Sunday and Monday look partly to mostly sunny with warmer temperatures.

High pressure will keep things sunny through Friday with daytime temperatures 12 to 18 degrees above normal.  Winds will be light.  

Saturday the high moves slightly back to the west and this allows a low pressure trough to drop southward along the Canadian coast (see map below).  This trough will pass across Northern California late Saturday and Sunday with a some clouds and a few showers over the higher elevations.  Temperatures will cool back to normal or a few degrees below by Sunday.  Gusty southwest to northwest winds are expected Saturday afternoon with strong and gusty north winds Sunday.

Monday high pressure is back along the coast.  Monday through the end of the week skies will be mostly clear.  Daytime temperature will be back above normal.  Strong and gusty north winds will continue through Tuesday.

The low pressure area is now over Southern California...see satellite picture below...and moving eastward.  Today we will be mostly sunny with some clouds south of Redding from the low.  Temperatures will continue above normal.  Light to moderate north winds are expected.  

Sunday through the Saturday high pressure will be along the coast (see map below).  Skies will clear with a few high clouds.  Temperatures Tuesday through Thursday will be 12 to 16 degrees above normal.  Periods of moderate north winds will occur.  

Another low pressure trough will approach the coast late Saturday and Sunday.   This system will also split apart and the southern portion will go into Central and Southern California.  The north state will see some clouds and cooler temperatures.

Sunny today with continued above normal temperatures and light wind.  This morning's satellite picture (below) shows the frontal system approaching the coast is splitting apart.  The stronger northern portion will go into Canada.  The weaker southern portion will approach the coast Thursday afternoon and then move across Southern California Friday and Saturday.   This system will bring a few clouds to Northern California Thursday and Friday with isolated showers possible in the Sierra's from Plumas county southward.  

Saturday the high pressure ridge will be rebuilding along the coast and will remain there through at least the middle of next week (see map below).  This means more clear skies...above normal temperatures... and periods of gusty north winds.

This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring

Not much change through Wednesday.   High pressure will remain along the coast and we will have mostly sunny skies with a few high clouds.  Temperatures will be above normal with gusty north winds in some areas today and light winds Tuesday and Wednesday.

It still looks like the frontal system that will approach the coast late Tuesday and Wednesday will split apart.  The question is how close to the coast will it get before it splits and after it splits how far south will the cutoff low drift before it is pulled back northeastward.  It now looks like the low will be pulled east to northeast late Thursday (see map below) and pass across Central California Friday.  This would bring some clouds to the north state Thursday afternoon through Friday with a few showers over the higher elevations.  

Skies will be clear Saturday and temperature be above normal with light to moderate north winds.  Sunday afternoon and Monday another low pressure trough will drop southward and brush the state.  Look for a few clouds and maybe a mountain shower with this system.

This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring

The mid and high clouds currently over Northern California are from a low pressure area and frontal system that is over western Canada (see satellite pic below).  This system is moving southeastward and will keep the northstate partly cloudy to cloudy through Sunday.  There could be a few light showers over the higher elevations.  Temperatures will be near normal and winds will be light southerly.  Monday will be partly to mostly sunny with temperatures a few degrees above normal.  Gusty north winds are expected.

Tuesday through Saturday the weather pattern will slightly change.  The high pressure ridge will moe a little westward.   The jetstream will split (see map below) as it approaches the coast with the main branch still to our north.  However, the southern branch will put a weak low pressure area off the Central and Southern California coast.  The north state will see partly sunny skies with a few mid and high clouds at times from the off shore low.  Temperatures will remain slightly above normal and winds will be light.

Another relatively dry low pressure trough could brush the north end of the state next Sunday and Monday.

Not a lot of change.  High pressure is still off the coast.  Today will be mostly sunny with temperatures 5 to 10 degrees above normal the gusty north winds will diminish this afternoon. There will be a few mid and high clouds Thursday as a frontal system passes by to our north.  Temperatures will cool a little and winds will be light.  Friday and part of Saturday look clear with temperatures a few degrees above normal.  Winds will be light.

Clouds will begin to increase late Saturday.   Sunday a weak low pressure trough will move through the Pacific Northwest with the southern end brushing Northern California (see map below).  We will see a few clouds with light showers possible over the higher elevations.

Monday through at least Wednesday high pressure will rebuild along the west coast.  Skies will be clear and temperatures will be back to 5 to 10 degrees above normal by midweek.  Gusty north winds will occur Monday through Wednesday afternoon.

Longer range maps do show the ridge weakening but not enough to allow stronger storms to pass through our area.

High pressure remains just off the coast.  Today through Wednesday Northern California will see mostly clear skies with temperatures 5 to 10 degrees above normal.  Gusty north winds will decrease Wednesday.

Thursday there will be a few mid and high clouds from a low pressure trough passing by to our north.  Temperatures will cool a few degrees and winds will be light.

Friday and Saturday will be clear.  Temperatures will be normal or a few degrees above.  Winds will be light.

Late Saturday and Sunday a weak low pressure trough will weaken the ridge and move across the north state (see map below).  This system will bring clouds to our area with light rain over the higher elevations and a chance of light showers in the valley.  Light to moderate south winds will precede this system. 

Skies clear our Monday as the high pressure area rebuilds along the coast.

Ref the question about high pressure ridges in yesterday's comment section.   I will answer it later this morning in the comment section of today's blog.

This morning's satellite picture (below) shows a low pressure area over the Pacific Northwest with little or no moisture (clouds) with it.  This low will drop southward over Nevada and end up over Southern California by late Sunday.  The low will bring a few mid and high clouds to Northern California today.  Temperatures will be a few degrees above normal.  Gusty north winds will move into the area later today.  Sunday will be sunny and cooler with the strong and gusty north to northeast winds continuing. 

Monday through Saturday the high will still be off the coast.  Low pressure troughs will ride over the high and through western Canada (see map below).   The north state will be mostly sunny with a few high clouds from the systems moving by to our north.  Temperatures will be 5 to 10 degrees above normal.  Strong and gusty north winds will continue through midday Tuesday with light to moderate north winds the rest of the week.

This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring

The mostly dry weather pattern will continue for at least the next week.  The high pressure ridge remains off the coast with the jetstream (storm track)  arching over the top of it and then dropping southward into western Canada. 

Today through midday Saturday Northern California will mostly sunny with some high cloudiness from the storms moving by to our north and east.  Temperatures will be 5 to 10 degrees above normal through Friday and then cool a little on Saturday.  Winds will be light until Saturday afternoon when southwest to northwest winds will increase. 

Late Saturday and Sunday a low pressure area will drop  southward along the California/Nevada border and end up over Southern California (see map below).  We will see a few clouds from this system with isolated light showers over the higher elevations.  Temperatures will drop back to below normal Sunday.  Gusty north to northeast winds expected Sunday.

Monday will be sunny with below normal temperatures.  Gusty north to northeast winds will continue.  Tuesday afternoon and Wednesday another low pressure area will drop southward across the north state.  This system will also bring a few showers to the  higher elevations.  Temperatures will cool and gusty north winds are expected.

This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring

Not much change in our weather pattern for the next 7 to 10 days.  A high pressure ridge is off the coast.  The jetstream is moving over the ridge and then dropping southward along the Canadian coast and then into the Great Basin.  Systems riding along this flow pattern will not have much moisture with them but will bring colder air into Northern California as they pass through.

The low that went through late Saturday and Sunday is now to our east.  Today through Saturday the north state will be mostly sunny.  Temperatures will start to warm....although wind sheltered areas of the north valley cold see freezing temperatures tonight.   Daytime temperatures will be back to 5-10 degrees above normal by midweek and should hold there through Saturday.  Gusty north winds will occur in some areas through Tuesday afternoon. with light winds Wednesday through Friday.

Late Saturday the next low pressure area will be dropping southward along the Canadian coast (see map below).  This system will bring a isolated showers to the higher elevations late Saturday and Sunday.  Temperatures will be back below normal by Sunday.  Gusty southwest to northwest winds will occur Saturday with gusty north winds Sunday.  Monday skies will clear with gusty north winds.

This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring

Clouds will begin increasing later today as the low pressure area now entering Western Canada drops southeastward toward the Great Basin.  This system will bring clouds to Northern California later today and Sunday with showers over the higher elevations Sunday.  The main affect of this system will be colder temperatures.  Today we will have temperatures several degrees above normal with several degrees below normal  on Sunday.  Freezing temperatures will occur in some part of the north valley Monday morning.  Gusty north winds will move into the area Sunday.  Skies will be clearing late Sunday.

Monday through Saturday high pressure will be along and over the west coast (see map below).  The north state will have mostly clear skies.  Temperatures will be back above normal by midweek.  The gusty north winds will continue until Tuesday afternoon. 

Longer range weather models show the high pressure ridge along or over the coast through mid February.
