 Normal high/ low temperatures for April 12-April 19 (high/low) Redding 72/47, Chico 73/44, Quincy 65/32, Chester 57/28, Susanville 63/34, Grass Valley 62/39, Weaverville 67/35, Mt. Shasta 59/35, Yreka 64/35, Alturas 60/29

  
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 continues just off the west coast.  Today through Monday Northern California will be mostly sunny with above normal temperatures.  Some areas in the north end of the valley will reach the upper 80s to 90 degrees.  Moderate north winds will occur today and Sunday.  

Late Monday a weak upper level low pressure area will drop southward out of Western Canada.  The low will be over Northern California Tuesday afternoon and Wednesday (see map below).  This system will bring a few clouds to the north state with isolated light showers over the foothills and mountains. 

Thursday through the weekend high pressure is back along and over the west coast.  We will see a return of sunny skies and above normal temperatures.  Gusty north winds will occur late Wednesday through midday Friday.  

One ray of hope is that the models are now showing at least light precipitation around the 25th to the 27th.

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 pressure area is over Nevada.  Today the areas along and east of the Sierra Nevada Crest will be partly cloudy to cloudy with isolated showers.  Temperatures will be below normal and gusty northeast to east winds will occur.  The areas west of the crest will see mostly sunny skies with a few clouds.  Temperatures will be near or a little above normal and gusty northeast winds are expected.

Thursday the low will begin to move eastward and a high pressure ridge reforms over the coast.  This ridge will continue to get stronger through the weekend (see map below).  The north state will see clear skies and warmer temperatures.  The Redding and Red Bluff areas could reach the 90 degree mark by Sunday and Monday.  The northeast winds will decrease early Thursday with a return of moderate north winds Friday and Saturday.

The high will weaken little next week.  This will allow some cooling but we will still be dry.

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 start out mostly sunny but the Northern and  Eastern sections of the north state will see a few clouds in the late afternoon and evening as a low pressure area drops from Canada toward Nevada.  Temperatures today will be slightly cooler.  Gusty northwest winds are expected.

Tuesday through Wednesday the low will be over Nevada (see map below).  This system doesn't have much moisture since it formed over the inland areas of Canada.  However, the weather along and east of the Sierra Cascade Crest will be totally differed than the weather west of the crest.  Tuesday and Wednesday along and east of the crest skies will be partly cloudy to cloudy with isolated light showers.  Temperatures will be below normal.  Gusty northeast to east winds are expected.  West of the crest will be mostly sunny with scattered clouds.  Temperatures will be near normal.  Strong and gusty northeast winds are expected.

Thursday the low will be moving eastward.  Skies will be mostly sunny and warming will occur both east and west of the crest.  Gusty northeast to east winds will continue.

Friday through at least the mid part of next week high pressure will be back over the coast.  Clear skies and above normal temperatures.  Winds will be decreasing Friday and light by Saturday and weekend.

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 low pressure area is passing through the Pacific Northwest.  This system will bring a few clouds to Northern California today with isolated light showers possible this morning over the higher elevations east of the valley.

Tuesday through at least early next week we will be under a weather pattern like the one shown on the map below.  This is a normal spring pattern.  A weak high pressure ridge is over the west with jetstream (storm track) to our north.  This will bring mostly sunny skies to the north state with above normal temperatures and relatively light 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. 

Another chance of rain bites the dust.   As expected the frontal system approaching the coast is splitting apart.   A few days ago it was thought that the southern portion would get pulled eastward Sunday and Monday as a low pressure trough moves through the Pacific Northwest.  The forecast map below shows that this is not expected to happen.  The southern low will stay well off the coast.  

Partly to mostly sunny and mild today and Sunday with continued above normal temperatures and light winds.   There will be a few clouds late Sunday and early Monday with isolated showers on the north coast and near the Oregon border.  

Tuesday through next weekend look mostly sunny with above normal temperatures and light 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. 

High pressure will remain along of just off the west coast through Saturday.   Northern California will be mostly clear with continued above normal temperatures.  Winds will be light.

Saturday a low pressure trough will develop or deepen in the Gulf of Alaska.  This trough will move eastward and as it does it will split apart with the southern portion being along the Northern California coast Monday (see map below).  The low will move slowly eastward and be east of our area by late Tuesday.  Clouds will increase late Sunday.  Monday and most of Tuesday the north state will be partly cloudy to cloudy with scattered showers and possible thunderstorms.  Snow levels will be 5000 to 6000 feet.  

Skies clear out late Tuesday and Wednesday we return to sunny with near normal temperatures.

Weather Discussion for Monday March 29, 2021

Normal high/ low temperatures for March 29-April 5 (high/low) Redding 69/45, Chico 70/43, Quincy 60/31, Chester 55/27, Susanville 57/30, Grass Valley 60/37, Weaverville 64/33, Mt. Shasta 58/31, Yreka 61/32, Alturas 57/27

  
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 still off the coast.  A low pressure area and frontal system are moving through Western Canada and the Pacific Northwest.  Today will be mostly sunny and temperatures will continue above normal.  Gusty north winds will move into the area during the day.

Tuesday through Thursday skies will be clear and daytime temperatures will be 8 to 12 degrees above normal.  Gusty north winds will continue through midday Wednesday.

Friday and Saturday a low pressure trough will begin to develop or deepen off the west coast (see map below).  Temperatures Friday and Saturday will slowly cool with light to moderate south winds in the afternoon.  

It is not uncommon to see differences in the forecast models in the 7 to 10 day forecast period.  What is interesting in this case is for the past 3 to 4 days the models have had a very consistent difference.  The European model splits the offshore trough and keeps a relatively strong portion off the coast through early next week.  The GFS (US) model splits the trough and moves a weak portion through Sunday and Monday.  We will hope the European is correct but expect something closer to the GFS.   Look for light rain or scattered showers Sunday and Monday.  Snow levels above 6000 feet.
