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 off the coast and is generating bands of rain and sending them across Northern California.  The low will move slowly eastward and should be east of our area by late Thursday.  Expect rain heavy at times today through midday Thursday.  Snow levels will be 4500 north and 5500 south lowering to 3000 north and 4000 south by late tonight and Thursday.  Gusty south winds will occur today and early Thursday.  The precipitation will turn to showers late Thursday and taper off during the night.   Friday we will have partly cloudy skies with a few showers mainly over the foothills and mountains. 

Saturday we will see partly cloudy skies and then more rain Sunday as a low pressure trough moves through (see map below).  Snow levels will be 3500 to 4500 feet.  

Monday through most of next week high pressure will be along the coast.  The north state will be mostly clear with above normal temperatures and periods of gusty north 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.

This morning's satellite picture (below) shows a low pressure area off the Central California coast. This system is moving slowly north-northeastward and will pass across Northern California Tuesday.  Late tonight and Tuesday Northern California will  see light rain with snow levels 3000 to 4000 feet.

Wednesday and Thursday a stronger low pressure trough will move through the area (see map below).  This system will bring light to moderate rain to the north state with snow levels 3500 to 4500 feet.   Gusty south winds are expected Wednesday.  The precipitation will turn to showers late Thursday and end early Friday.  Late Friday and Saturday we will see partly cloudy to partly sunny skies and then a weak frontal system will pass through Sunday with rain on the coastal and northern mountains and showers elsewhere.  Snow levels will 5000 to 6000 feet. 

A high pressure ridge will be along the coast Monday and should hold there for several days.

Weather Discussion for Saturday January 12, 2019

Normal high/ low temperatures for Jan 7-Jan 14  (high/low) Redding 55/36, Chico 53/35, Quincy 45/23, Chester 42/19, Susanville 40/21, Grass Valley 54/32, Weaverville 47/28, Mt. Shasta 44/27, Yreka 44/24, Alturas 41/17

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 be dealing with a split jetstream for the next couple of days.   The system that I thought would bring a few showers late yesterday and today is now moving inland over southern California.   The frontal system you see on the satellite picture below, out to our west will split apart later today and the southern portion will move slowly toward the coast.  Monday it will be off the Central California coast and then Monday night and Tuesday it will lift northward over Northern California.   Today and Sunday the north state will be partly to mostly sunny with above normal temperatures.  Clouds increase Monday and then Tuesday we will have light rain or showers with snow levels will be around 5000 feet.

Wednesday and Thursday a couple of fast moving storms will move across Northern California (see map below), bringing light to moderate rain to our area with snow levels 3500 to 4500 feet north and 5500 feet south.  These systems will be preceded by gusty south winds.   

Friday and part of Saturday there will be a break and then a weak front will bring showers to the coast and northern mountains.

Weather Discussion for Wednesday January 9, 2019

Normal high/ low temperatures for Jan 7-Jan 14  (high/low) Redding 55/36, Chico 53/35, Quincy 45/23, Chester 42/19, Susanville 40/21, Grass Valley 54/32, Weaverville 47/28, Mt. Shasta 44/27, Yreka 44/24, Alturas 41/17

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 main band of precipitation went through last night.  However, the low pressure trough is still along the coast and moving slowly eastward.   This low will send bands of showers across Northern California today.  Snow levels will be 5000 to 6000 feet north and higher south.  

Thursday and most of Friday we have partly cloudy skies.   A weak low pressure area will move through Central California late Friday and Saturday with another weak system moving through late Saturday and Sunday. These systems will bring scattered light showers to the north state.  Snow levels will be 5000 to 6000 feet.

It still looks like a stronger low pressure trough will move into the area late Tuesday and Wednesday (see map below).

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 shows another frontal system headed toward the coast.  This pattern of a low pressure trough and frontal system every couple of days will continue for the next 7 to 10 days (see map below).

Today Northern California will be partly cloudy to cloudy with a few light showers mainly over the higher elevations.  Snow levels will be 5000 feet.  Tuesday afternoon the next front moves inland.   We will see locally moderate rain with snow levels 5000 feet north and 6500 feet south.  Gusty south winds are expected late Tuesday and Wednesday.

Thursday and early Friday the north state will be partly cloudy to cloudy.   Late Friday and Saturday another storm will move through with gusty winds and more rain.  Snow levels will be around 4000 feet north and 5000 feet south.  Another frontal system will come through  late Saturday and Sunday with more rain and snow levels 4000 north and 5000 feet south.   These fronts will preceded by gusty south winds.

Weather Discussion for Saturday January 5, 2019

***LOW SNOW LEVELS IN THE NORTH TODAY.  WET AND WINDY THIS WEEKEND***

Normal high/ low temperatures for Dec 31-Jan 7  (high/low) Redding 54/34, Chico 52/34, Quincy 44/22, Chester 40/18, Susanville 38/19, Grass Valley 52/30, Weaverville 45/27, Mt. Shasta 42/25, Yreka 43/24, Alturas 40/14

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 first in a series of frontal systems is moving into Northern California today.  Expect locally heavy rain today.  Due to the cold trapped air in the north snow levels will locally 1000 to 1500 feet from Redding northward.  Elsewhere snow levels will be 3000 to 4000 feet.   Areas where the cold air isn't trapped will see southerly winds with gusts to 40 to 45 mph in the valley and 55 to 60 mph over the higher elevations.  

Sunday another low pressure trough will move through with moderate to heavy precipitation.  Snow levels will be 2000 to 3000 feet north and around 4000 feet south.   More strong gusty south winds will precede this system.

The precipitation will end by early Monday with partly cloudy skies by afternoon.  Late Tuesday and Wednesday another fairly strong storm system will move through.   We will see more rain with snow levels 4000 feet north and 5000 feet south.   Another round of gusty south winds will precede this storm.

We will see a break Thursday and early Friday.   Late Friday another low pressure area will be off the coast (see map below).  This will send more storms through the area next weekend.

Short version....wet and windy for the next week.
