Weather Discussion for Wednesday Dec. 16, 2020

 Normal high/ low temperatures for Dec 14-Dec 21  (high/low) Redding 53/36, Chico 54/35, Quincy 45/24, Chester 41/21, Susanville 41/21, Grass Valley 52/31, Weaverville 46/29, Mt. Shasta 41/25, Yreka 44/25, Alturas 42/18

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 and frontal system are approaching the coast and will spread rain over Northern California later today.  The rain will end late tonight.  Snow levels will be near 5000 feet lowering to 3500 to 4000 feet tonight.  Thursday there will be a few showers over the mountains in the morning with decreasing clouds during the day.

Friday through the weekend a weak high pressure ridge will be over the west coast (see map below).  The north state will be mostly sunny with a few clouds at times from fronts moving by to our north.  Temperatures will be a few degrees above normal and winds will be light. 

Early next week the high will shift westward.  This will allow temperatures to cool to normal.  However, it will still be dry.

  1. Does this rather poor rain season remind you of any other? An analogue?

  2. Not yet. Weak La Nina does not have good correlation with our precip. No monster high pressure area to our north. Jetstream is just to our north and we are close but no rain. I would think we would see a change in Jan but still be below normal for the rain year.
