Partly to mostly sunny today with near normal temperatures and light wind.  Tuesday through the weekend we will be under a weather pattern like the one shown on the map below.  The jetstream will run across the Pacific and enter the coast just north of our area.  Fast moving frontal systems will ride along the jetstream and as they move through will bring clouds and light rain or showers.  The first system will move through late Tuesday and early Wednesday.  Snow levels will be 4000 to 5000 feet.  There will be a brief break and then another frontal system Thursday and Friday.   Snow remain 4000 to 5000 feet. 

At this time it looks like the weekend will be partly cloudy with a isolated showers possible Saturday morning.

Normal high/ low temperatures for Dec-2-Dec 9  (high/low) Redding 59/38, Chico 60/38, Quincy 51/26, Chester 46/24, Susanville 47/25, Grass Valley 56/34, Weaverville 51/31, Mt. Shasta 47/28, Yreka 49/27, Alturas 48/21
  
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 low off the coast is moving slowly eastward.  This low is similar to the last one but will take a more northeastward track as in moves inland late today and earlier Sunday.  Northern California will receive light to moderate rain today, with gusty south winds.  Snow levels will be 5000 feet north and 6000 feet south.  The precipitation turns to showers Sunday morning and then decreases during the day.  

Next week will be caught between a high pressure ridge to our south that will be trying to push northward and an active jetstream that will be running across the Pacific and into the coast.  The effect of the ridge will be to push storms a little northward as they hit the coast.  Monday and early Tuesday we will be partly to mostly sunny.   Tuesday night and Wednesday a weak frontal system will brush the north state (see map below). This system will bring showers to the north coast and northern mountains.   It will be followed by another weak frontal system moving through Thursday and Friday.

The low pressure area is moving eastward and is now over Nevada.  There are a few showers east of the valley this morning but they will dissipate during the day.  The next low pressure area will spread precipitation of the area Saturday and the rain will continue through Monday afternoon.   Because of trapped cold air the snow levels will start out 500 to 1500 feet from Redding northward and 2000 to 3000 feet to the south.  Snow levels will rise Sunday to 4000 feet north and 6000 feet south.  The rain will turn to showers Monday.

Tuesday and Wednesday we will have partly cloudy skies with a few showers mainly over the foothills and mountains.

Thursday another low pressure trough will reach the coast (see map below).   This will bring more rain and snow to the area Thursday and Friday.  Snow levels will be 5000 to  6000 feet.

Weather Discussion for Wednesday Nov. 27, 2019



Normal high/ low temperatures for Nov 25-Dec 2  (high/low) Redding 59/38, Chico 60/38, Quincy 51/26, Chester 46/24, Susanville 47/25, Grass Valley 56/34, Weaverville 51/31, Mt. Shasta 47/28, Yreka 49/27, Alturas 48/21
  
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 blog will issue this Friday due to incoming Saturday storm.

The low pressure area is now over Southern Oregon and Northern California.  It will wobble around that area and just off the coast through Thursday morning and them move eastward.  Today through Thursday morning there will be scattered showers over the foothills and mountains, with isolated showers in the valley.  Snow levels will be 1000 to 1500 feet Redding northward and 2000 to 2500 feet to the south.  Gusty south winds will continue in some areas until late afternoon.  Thursday afternoon the showers will be mostly over the areas east of the Sacramento Valley. Tonight freezing temperatures will occur in some areas of the north valley.  Colder weather is expected Thursday night and Friday morning   The north valley will be in the mid to upper 20s.

Friday skies will be partly sunny with a few clouds over the mountains.  There could be a few snow flurries east of the Sierra Cascade Crest.

Saturday the next low pressure area approaches the coast (see map below).  This low is coming from the west but will be pulling moisture up from the southwest ahead of it.  This means it will be a much warmer storm.  However, once again we might be dealing with cold trapped air from Redding northward and in the mountain valleys.  This means snow levels very low initially then rising rapidly Sunday.  Look for precipitation to start late Saturday afternoon and continue on and off through Tuesday.  Snow levels Saturday night and early Sunday 500 to 1000 feet Redding northward and 2000 to 3000 feet elsewhere.  Snow levels rising to 5000 to 6000 feet by midday Sunday.

Special Weather Discussion for Tuesday Nov. 26, 2019

***LOW SNOW LEVELS...STRONG WINDS TONIGHT***

Normal high/ low temperatures for Nov 25-Dec 2  (high/low) Redding 59/38, Chico 60/38, Quincy 51/26, Chester 46/24, Susanville 47/25, Grass Valley 56/34, Weaverville 51/31, Mt. Shasta 47/28, Yreka 49/27, Alturas 48/21
  
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 is a Tuesday morning update for the incoming storm.   The low pressure area is rapidly developing along the Oregon coast and is dropping southward.  The low will move into Northern California tonight and then move slowly eastward late Wednesday and Thursday.  

Clouds will increase today with precipitation spreading over Northern California later today and tonight.   Winds will also increase.   Strongest winds will be on then north coast and exposed areas north of Redding.  Although just about all areas will see fairly strong winds  South winds over the exposed areas north of Redding will gusty to  80+ mph tonight.  Winds in the valley will gust to 60 mph in the north end with light winds in the Sacramento area.  Winds over the Sierra will gust to 65 to 75 mph.. Precipitation will turn to showers by Wednesday afternoon and will end Thursday. 

Now about snow levels.  Snow levels overall will be 1500 feet north and 2500 feet south. The exception will be the Redding area and Sacramento River canyon north of Redding.   Currently there is a large area of cold dry air trapped in the north valley.   The south winds will tend to push that air out as they increase today.  However, sometimes the cold air is so stable the winds ride over the top of it and this results in lower snow levels in the north end of the valley.   So Redding will either have not much wind and snow tonight and early Wednesday or snow this evening and windy and rainy later tonight with showers Wednesday.  At this time I think the snow levels start out at 500 feet this afternoon and evening and rise up to 1000 to 1500 feet tonight when the south winds move in.

Friday we will have a break and then another low pressure area Saturday through Monday.  Once again we will be dealing with cold trapped air so snow levels may be low in the north.

***COLDER AND LOW SNOW LEVELS
VERY STRONG SOUTH WINDS TUESDAY NIGHT***

Normal high/ low temperatures for Nov 25-Dec 2  (high/low) Redding 59/38, Chico 60/38, Quincy 51/26, Chester 46/24, Susanville 47/25, Grass Valley 56/34, Weaverville 51/31, Mt. Shasta 47/28, Yreka 49/27, Alturas 48/21
  
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 south end of a frontal system is brushing Northern California this morning with clouds and isolated showers near the Oregon border. 

Tuesday things get interesting.  It now looks like the cold low pressure area will rapidly intensify as it approaches Northern California.  This will make the storm wetter and windier.  Clouds will increase Tuesday with precipitation spreading southward over the north state during the afternoon and evening.  Snow levels will start out at 500 to 1000 feet from Redding northward and 2000 to 2500 feet in the Tahoe area.  Snow levels will rise up slightly Tuesday night and early Wednesday.  Winds will increase Tuesday afternoon with wind gusts to 60 mph in the north end of the valley and 70 mph over the higher elevations Tuesday night.  The low will be over Northern California Wednesday (see map below) and will be moving eastward.  The precipitation will turn to showers by Wednesday afternoon.  The winds will decrease by midday Wednesday.

Thursday we will have partly cloudy skies with showers over the foothills and mountains with a chance of an isolated shower in the valley.  Snow levels will continue low. 

Friday looks mostly sunny and cool and then another low pressure area will spread more rain over the area late Saturday through early Monday.  Due to cold trapped air the snow levels could be low in the north end of the valley.

The low pressure area is now over the California/Nevada border and is dropping southeastward.  The low be will off the Southern California coast later today and them move eastward late Thursday and Friday.  There will be some clouds today and Thursday along and east of the Sierra Cascade Crest with a few light showers possible in the Tahoe area.  The rest of the north state will be mostly clear through Friday.  Temperatures will be cooling but still a little above normal.  Strong and gusty northeast winds will occur today and tonight but will begin to decrease Thursday morning and should be gone by afternoon.  Winds will be light Friday.

Saturday and Sunday we will have sunny skies with temperatures a few degrees above normal.  Winds will be light.

Monday and early Tuesday a low pressure trough will move through the Pacific Northwest (see map below).  The southern end of this system will bring clouds to the north state with a few light showers over the areas north of Redding and Modoc and Lassen counties.  Temperatures will cool with gusty southwest to northwest winds Monday afternoon.

The models show a stronger a colder low pressure trough moving through our area late Tuesday and Wednesday.  This system could bring showers to much of the north state.
