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.
