Weather Discussion for Tuesday Jan. 26, 2021

 Normal high/ low temperatures for Jan 25-Feb 1  (high/low) Redding 56/36, Chico 57/37, Quincy 47/23, Chester 43/20, Susanville 42/21, Grass Valley 54/31, Weaverville 50/28, Mt. Shasta 45/26, Yreka 46/24, Alturas 43/16

  
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 very strong and cold low pressure area is headed toward Northern California.  Moderate to heavy precipitation will start late this afternoon and evening and continue through Wednesday.  Periods or rain or showers will occur Thursday as the low moves east of our area.  The two main features of this storm are the low snow levels and strong winds.  It looks like the snow level starts our at 500 to 1000 feet in the north and 1500 to 2000 feet south and will rise to 2500 to 3000 feet north and 3000 to 3500 feet south by Wednesday afternoon.  Southeast to southwest winds will increase later today and strong winds are expected tonight and early Wednesday. Gust in the north valley will be 50 to 55 mph with higher gusts over the ridges.

A weaker frontal system will move across Northern California Friday afternoon and Saturday with light to moderate rain.  Snow levels will be 1500 to 2500 feet north and 3500 feet south.  

Another low pressure area will be off the coast by midday Sunday (see map below).  This system will bring more rain to the north state Sunday afternoon through early Tuesday.  Snow levels will be 3000 to 4000 feet.

Weather Discussion for Monday Jan. 25, 2021

Normal high/ low temperatures for Jan 25-Feb 1  (high/low) Redding 56/36, Chico 57/37, Quincy 47/23, Chester 43/20, Susanville 42/21, Grass Valley 54/31, Weaverville 50/28, Mt. Shasta 45/26, Yreka 46/24, Alturas 43/16

  
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 blog will be updated Tuesday due to the incoming storm.

The main part of the storm has moved east or our area.  There will still be a few residual snow showers over the mountains through mid afternoon.  Skies will be clearing this evening and tonight will be cold with freezing temperatures in many areas in the north valley.  

Clouds begin to increase Tuesday as a strong cold low pressure area approaches the coast.  The low will be over Northern California Wednesday and then east of the state Thursday (see map below).  Precipitation starts Tuesday night with heavy rain and strong and gusty southeast to southwest winds Tuesday night and early Wednesday.  Light to moderate rain will occur Wednesday afternoon with showers Wednesday night and Thursday.  Snow levels will be low.  Normally in Redding you don't see strong south winds and snow.  I have only seen it a couple of times in 45 years.  This may be one of those events.  Tuesday night and early Wednesday the snow level will be 500 to 1000 feet in the north and 2000 feet south. The snow level will start to rise late Wednesday morning and by Wednesday night be 2500 to 3000 feet north and higher south.

Friday a weaker frontal system will bring light rain or showers to the north state.  Saturday looks partly cloudy with showers mainly over the foothills and mountains and then another storm system will bring rain late Sunday and Monday.

Weather Discussion for Saturday Jan. 23, 2021

***COLD STORMS COMING***


Normal high/ low temperatures for Jan 18-Jan 25  (high/low) Redding 57/36, Chico 56/36, Quincy 46/23, Chester 43/20, Susanville 41/21, Grass Valley 55/33, Weaverville 49/28,  Mt. Shasta 46/27, Yreka 45/24, Alturas 42/17

  
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.

Today will be partly to mostly sunny and cool with light to moderate north winds.   Sunday another cold low pressure trough moves across Northern California with light precipitation.  Snow levels will be 500 to 1000 feet north and 2000 to 3000 feet south.  Monday skies will be partly cloudy with a few snow flurries over the higher elevations.  

Tuesday a cold and strong low pressure area will move to just off the coast and the will move slowly eastward across Northern California Wednesday and early Thursday (see map below).  This system will bring heavy precipitation and strong southeast to southwest winds to the north state.  Snow levels will be low....it is a cold storm and there will probably be cold air trapped in the north end of the Sacramento Valley.  Snow levels will be 500 to 1500 feet in the north and 2000 to 3000 feet south. I am leaning more toward the 1000 to 1500 foot level around Redding.  This is because I think the south winds will scour our much of the trapped cold air.  If the cold air stays in place then the snow levels will be near 500 feet in the Redding area.  Snow levels will rise a little Wednesday afternoon and Thursday. The precipitation will taper off during the day Thursday with just a few mountain snow showers Friday.

Another storm will bring more rain and snow to the area Saturday and Sunday.  This will be another cold storm but snow levels will be a little higher.

Normal high/ low temperatures for Jan 18-Jan 25  (high/low) Redding 57/36, Chico 56/36, Quincy 46/23, Chester 43/20, Susanville 41/21, Grass Valley 55/33, Weaverville 49/28,  Mt. Shasta 46/27, Yreka 45/24, Alturas 42/17

  
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.

The high pressure ridge that is off the coast is moving slowly back to the west. This will bring in colder weather with possibly heavier precipitation next week.  Today will be sunny and cooler with the north winds will be ending this morning.  Clouds will begin to increase Thursday afternoon as a low pressure area drops southward along the Canadian coast.  The low will move through Northern California Friday with scattered light showers.  Snow levels will be 1500 to 2500 feet north and higher south.

Saturday we will see clearing skies with cool temperatures.  Late Sunday and early Monday another cold low pressure area will move through with light precipitation.  Snow levels will be 1000 to 1500 north and 2500 to 3000 feet south.  The map below shows the weather pattern for next Tuesday afternoon and Wednesday.  Note the low is further off the coast.  This would be a wetter system.  Snow levels will be low.  The caveat is that the models are not in agreement on location and strength of this pattern.

Weather Discussion for Monday Jan. 18, 2021

 Normal high/ low temperatures for Jan 18-Jan 25  (high/low) Redding 57/36, Chico 56/36, Quincy 46/23, Chester 43/20, Susanville 41/21, Grass Valley 55/33, Weaverville 49/28,  Mt. Shasta 46/27, Yreka 45/24, Alturas 42/17

  
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.

The high pressure ridge that is along and over the west coast is beginning to move back to the  west.   This will allow temperatures to slowly cool.  Skies will be clear through Wednesday.  Strong and gusty northeast winds will occur today and Tuesday with lighter north winds Wednesday.  

As the high pressure ridge moves back to the west is allows colder air to drop southward from Alaska.  Friday a low pressure area will be off the Northern California coast (see map below).  This low will have limited moisture but will bring light showers to Northern California with snow levels 2000 to 3000 feet.  

Saturday and Sunday look mostly sunny and cool with north winds.  Another storm will bring showers to the area late Sunday and Monday.

Weather Discussion for Saturday Jan. 16, 2021

Normal high/ low temperatures for Jan 11-Jan 18  (high/low) Redding 56/36, Chico 54/35, Quincy 45/23, Chester 43/20, Susanville 41/21, Grass Valley 54/33, Weaverville 48/28,  Mt. Shasta 45/27, Yreka 45/24, Alturas 42/18

  
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.

High pressure is along the west coast.  Today and Sunday will be mostly sunny with daytime temperatures 10 to 15 degrees above normal.  North winds will be increasing in some areas.  Strong and gusty north winds will occur over Northern California Sunday.  

Monday the high will begin to shift slowly westward.  Skies will be clear through early Thursday with daytime temperatures cooling back to near normal by Thursday.  Gusty north winds will continue through Thursday morning with strongest winds Monday and early Tuesday.

Friday the high will have moved far enough westward that the jetstream is dropping from Northern Alaska (see map below).  This is not a very wet pattern...but it will bring very cold air into Northern California.  The models indicate the high could shift a little further westward next weekend which would bring moisture into the cold airmass.
