"Who Stopped the Rain" was a CCR song from the  70's.  The answer to this question is shown in the map below...a huge high pressure ridge that extends from off the Baja coast northward to the Arctic.  This ridge is building along the coast today and will be a full strength by the weekend and should hold there through mid February.  

This means mostly sunny skies with a few high clouds.   Daytime temperatures above normal...this weekend and early next week we see record temps for this time of year.  There will be periods of gusty north winds.

I am not sure of the cause of this ridge in December and again now.  Could be linked to the Arctic Oscillation.

Weather Discussion for Monday January 29, 2018

Normal high and low temperatures for Jan 29-Feb 4  (high/low) Redding 58/37, Chico 57/37, Quincy 48/24, Chester 43/21, Susanville 43/22, Grass Valley 54/31, Weaverville 51/28, Mt. Shasta 48/ 27, Yreka 47/24, Alturas 44/17

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.

 We will see a few clouds today and Tuesday as frontal systems move through the Pacific Northwest and brush the north end of California.  There could be a few light showers over the northwest corner of the state.  

Starting Wednesday and for the next 10 days and possibly through mid February there will be a strong high pressure ridge along the west coast (see map below).   This means a return of dry weather with mostly sunny days, above normal daytime temperatures and periods of gusty north winds.

Weather Discussion for Saturday January 27, 2018

Normal high and low temperatures for Jan 22-Jan 29  (high/low) Redding 57/38, Chico 57/37, Quincy 47/24, Chester 43/22, Susanville 42/23, Grass Valley 55/33, Weaverville 49/28, Mt. Shasta 46/ 27, Yreka 46/24, Alturas 43/17

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.

A weak frontal system is brushing the north end of the state today.  This system will bring clouds and a few light showers to the north coast, Trinity, Siskiyou, Shasta, Lassen, and Modoc counties.  Snow levels will be 2500 to 3000 feet.  The rest of the north state will be partly sunny.

High pressure is slowly building along the west coast.  This will push the jetstream northward.  Sunday through Tuesday will be partly sunny to partly cloudy with light winds.  Tuesday there could be a few showers over the northwest corner of the state from a storm moving by to our north.  

Wednesday through next weekend a strong high pressure ridge will be along the west coast (see map below).  This will bring mostly clear skies to our area with above normal daytime temperatures.  Winds will be light.

Weather Discussion for Wednesday January 24, 2018

Normal high and low temperatures for Jan 22-Jan 29  (high/low) Redding 57/38, Chico 57/37, Quincy 47/24, Chester 43/22, Susanville 42/23, Grass Valley 55/33, Weaverville 49/28, Mt. Shasta 46/ 27, Yreka 46/24, Alturas 43/17

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.

This morning's satellite picture (below) shows an impressive frontal system moving onto coast.  This system will bring moderate to locally heavy precipitation to Northern California today along with gusty south winds.  Snow levels will be 3500 to 4500 feet.   The rain will taper off this evening as the front moves east.  Thursday the upper level low pressure trough will be over our area.   This system will bring scattered showers to the north state with snow levels 1500 to 2500 feet north and a little higher south.   The showers will end Friday morning.

Saturday high pressure begins to build northward over California (see map below).   This will push the jetstream or storm track northward.   Saturday through Monday we will have partly cloudy to cloudy skies.   Saturday and Monday frontal system will pass by to north.  These systems will bring light showers to the north coast, coastal and northern mountains and the Sierra Cascades north of Plumas county.   There could be a light sprinkle in the valley north of Red Bluff.  Snow levels will be around 5000 feet.  

Tuesday through the end of next week the high pressure area will be along the coast and we will have mostly clear skies with above normal temperatures.

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 cold storm that brought rain and snow to the area yesterday is moving eastward.  There will be a few light showers this morning but they will end by afternoon.  Partly cloudy Tuesday and then the low pressure area that is is currently in the Gulf of Alaska (see satellite picture below), arrives Wednesday.  This system will bring moderate rain to the area Wednesday with snow levels 2500 to 3000 fee north and slightly higher south.  Thursday the north state will see showers with snow levels 1500 to 2000 feet north and 3000 feet south. 

A weak high pressure ridge will be along the coast Friday.   Skies will be partly cloudy to  partly sunny with temperatures remaining below normal.   Saturday a weak low pressure trough will brush the north end of the state (see map below).   This system will bring light precipitation to the foothills and mountains with a chance of showers in the north end of the valley.  Snow levels will be 4000 to  5000 feet.   Another weak front will move through late Monday.
