Weather Discussion for Wednesday January 10, 2018

Normal high and low temperatures for Jan 8-Jan 15  (high/low) Redding 55/36, Chico 54/36, Quincy 46/23, Chester 42/21, Susanville 41/21, Grass Valley 53/33, Weaverville 46/27, Mt. Shasta 44/ 26, Yreka 44/25, Alturas 41/16

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 beginning to rebuild along and off the west coast.  There is still a lot of moisture over Northern California and this will result in a few light showers this morning over the areas east of the valley.  Skies will be partly cloudy to partly sunny by afternoon.   Thursday a low pressure trough and frontal system will move through the Pacific Northwest.  The southern end of this system will bring clouds to the north state with scattered light showers north of Redding.

Friday through Sunday high pressure will be over the west coast.   We will see partly to mostly sunny skies with above normal daytime temperatures and light winds.

Still looking for a return of winter weather next week.  The jetstream will increase across the Pacific and the high pressure ridge will weaken (see map below).   The first storm will reach the coast Monday night and Tuesday.  This system will bring light precipitation to Northern California with snow levels 5000 to 6000 feet.  A stronger system will move in late Wednesday and Thursday with another storm on the weekend.
