The persistent high pressure ridge is still just off the coast.   Today through Friday we will see mostly sunny skies with temperatures 7 to 15 degrees above normal.  Gusty north winds will occur in some areas today through midday Tuesday.  Winds will be light Wednesday through Friday.

Saturday a low pressure trough will be approaching the coast (see map below).  This system will have limited moisture.  We will see some clouds Saturday afternoon through Sunday afternoon with light showers over the foothills and mountains with a chance of a light shower in the north end of the valley.  Gusty southwest to northwest winds will occur Saturday afternoon with gusty north winds by Sunday afternoon.  

Monday the high pressure ridge will be off the coast and we will see clear skies and gusty north winds.

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.

Normal high/ low temperatures for Feb 17-Feb 24 (high/low) Redding 60/41, Chico 61/40, Quincy 53/26, Chester 47/24, Susanville 47/26, Grass Valley 56/35, Weaverville 55/30, Mt. Shasta 48/30, Yreka 52/28, Alturas 47/21

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.

Normal high/ low temperatures for Feb 10-Feb 17 (high/low) Redding 60/40, Chico 61/38, Quincy 51/26, Chester 47/23, Susanville 46/24, Grass Valley 56/35, Weaverville 54/30, Mt. Shasta 48/28, Yreka 50/27, Alturas 46/20

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.
