Normal high and low temperatures for Feb 11-Feb 18  (high/low) Redding 60/40, Chico 61/39, Quincy 52/26, Chester 46/23, Susanville 46/24, Grass Valley 56/35, Weaverville 55/30, Mt. Shasta 48/ 2730, Yreka 51/28, Alturas 46/20

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 along the Canadian and Pacific Northwest coasts.  This system is moving southeastward and its southern portion will move across Northern California late tonight and Sunday.   This system does not have a lot of moisture but it is cold and will bring showers to the foothills and mountains with snow levels around 2000 feet.  Gusty southwest to northwest winds will occur Sunday.  The showers will end by early Monday.   Monday and Tuesday the north state will be partly cloudy to partly sunny with gusty north winds on Monday.  A very cold airmass will still over the area and Monday night and Tuesday night will be the coldest nights so far this winter....especially in the wind sheltered valleys.  Some areas in the Northern Sacramento Valley will be in the upper 20s.  

Wednesday through next weekend we will be under a weather pattern like the one shown on the map below.  The jetstream or storm track will continue to run from off the Canadian coast into the Central U.S.   We will see partly to mostly sunny skies with daytime temperatures a few degrees above normal.
