Weather Discussion for Saturday March 31, 2018

Normal high and low temperatures for March 26-April 2  (high/low) Redding 69/44, Chico 69/43, Quincy 60/30, Chester 55/27, Susanville 57/30, Grass Valley 61/38, Weaverville 63/33, Mt. Shasta 57/ 31, Yreka 60/31 Alturas 56/26

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 Northern California will be partly sunny with high cloudiness.  Temperatures will continue above normal with light winds.   Easter Sunday will be sunny with continued above normal temperatures.  

Spring and fall are the times when the computer models seem to have the most trouble.  We are transitioning between our wet and dry weather patterns.  Starting Monday we will have one thosetimes.   The high pressure ridge that has been along the coast will weaken and the jetstream will begin to drop southward.   Where the models disagree is where the jetstream or storm track ends up.  One run it is over San Francisco by midweek.   The next run like the one shown below it stays to our north.   The one thing they do agree on is starting next week we will have a series of frontal systems move across the north state.  Probably weak systems.  

So after all the excuses here is what I think next week will bring.  One front goes through late Monday and Tuesday with clouds and isolated showers north of Redding.   The next system will be late Wednesday and Thursday and will be just a little stronger with clouds and showers over the mountains with maybe a sprinkle in the north valley.  The best chance of widespread rain and showers will be the system late Friday and Saturday.

Weather Discussion for Wednesday March 28, 2018

Normal high and low temperatures for March 26-April 2  (high/low) Redding 69/44, Chico 69/43, Quincy 60/30, Chester 55/27, Susanville 57/30, Grass Valley 61/38, Weaverville 63/33, Mt. Shasta 57/ 31, Yreka 60/31 Alturas 56/26

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 and over the west coast.  Today and Thursday we will see sunny skies with daytime temperatures 10 to 15 degrees above normal.  Gusty north winds will occur in some areas today.  

Friday the high pressure ridge will begin to slowly weaken.  This will allow temperatures to slowly cool.  We will continue to have partly to mostly sunny skies with a few high clouds from frontal systems moving by to our north.  Winds will be light. 

The ridge will have weakened enough by next Tuesday to allow the jetstream drop close to Northern California (see map below).   Tuesday and early Wednesday a weak frontal system and low pressure trough will move through the north state.  This system will bring showers to the higher elevations and a chance of a sprinkle in the valley.

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 building along the west coast and will hold there for the next 5 to 7 days (see map below).   Today through Thursday we will see mostly sunny skies with temperatures 10 to 15 degrees above normal by Wednesday.  This means some north valley locations will be over 80. Gusty north winds will occur in some areas through Wednesday. 

The high will begin to weaken a little on Friday.  This will cool temperatures slightly.   Saturday afternoon and again Monday weak fronts will brush the north end of the state with a few clouds.  There could be isolated showers near the Oregon border.

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 just off the coast and is moving eastward.  This system will move across Northern California today with showers and possible thunderstorms.  Snow levels will be 2000 feet north and 2500 to 3000 feet south.  Sunday there will be some lingering showers over the mountains which will end by late afternoon.

Monday high pressure begins to build along and over the west coast and will hold there for the next 5 to 7 days (see map below).  Skies will be mostly sunny with a few high clouds.  Temperatures will be warming and by mid week will be 12 to 18 degrees above normal which means some north valley locations will break the 80 degree mark.  Gusty north winds will occur in some areas Monday through Thursday.

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.

Two different low pressure areas will move through Northern California during the next several days.   The first system is to our west and the second is currently in the Gulf of Alaska (see satellite picture below).  The first system will spread rain over the area today through Thursday afternoon.  This is a warm system and snow levels will be 6000 feet or higher.  There will be a short break Thursday afternoon through early Friday.  

Friday the colder system will be along the coast and will remain there through Saturday (see map below).  The first shot of precipitation from this system will move through Friday.  This will be a colder storm and snow levels will be 3000 feet north and slightly higher south.  Gusty south winds will precede this storm. 

Another brief break late Friday and early Saturday and then the next band of rain moves through.  Snow levels will be 2000 feet north and 3000 feet south.  The precipitation will end early Sunday with decreasing clouds Sunday afternoon. 

High pressure will be along the coast by Monday should hold there for at least 5 to 7 days.  This means a return to spring weather next week.

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 a large low pressure area to our west.  This system is moving slowly eastward and will move across Northern California Tuesday and Wednesday.  A colder low pressure trough will drop southward from the Gulf of Alaska and be along the coast Thursday afternoon and Friday (see map below) and will move across the north state Saturday. 

Clouds will increase tonight with rain Tuesday through Wednesday evening.  Wednesday night and part of Thursday we will have scattered showers and then more rain Thursday night and Friday with showers on Saturday.  The first storm is warm so snow levels will start out at 5000 feet and rise to above 6000 feet.  The second storm is cold so snow levels will start dropping Thursday and be down to around 3000 feet by Thursday afternoon and Friday. 

Late Sunday and Monday a frontal system will brush the north state with showers mainly over the higher elevations.
