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.

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.

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.
