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.

 Another relatively dry low pressure trough is moving through the area today.  The low is currently over the Pacific Northwest and is moving southeastward.  This system will bring a few light showers to the foothills and mountains with snow levels 1000 to 1500 feet north and 2500 feet south.  This system will be east of our area by tonight.

Clouds will increase again Sunday afternoon as another low pressure area drops southward.  This system will be a little wetter and will bring showers to most of the area Sunday night and early Monday.  The precipitation in the valley will be light and mainly in the north.  Snow levels will be 1500 to 2000 feet north and 2000 to 3000 feet south.  However, due to trapped cold air the canyons the snow levels from Redding northward will be locally 500 to 1000 feet.   This system will be east of our area by Monday afternoon.

Tuesday looks sunny but clouds will increase Wednesday as a low pressure trough deepens along the coast.  Thursday through Saturday a large low pressure trough will be along the west coast (see map below).  Northern California will have periods or rain Wednesday night through early Saturday.  Snow levels will start out 2000 to 3000 feet north....locally 500 to 1500 feet due to trapped cold air...and 3000 to 4000 feet south.  Snow levels will drop to 1500 to 2000 feet north and 2000 to 3000 feet south by Thursday night and Friday.   Gusty south winds are expected late Wednesday and Thursday. Saturday we will have partly cloudy skies with showers mainly over the higher elevations. 

Sunday looks like a short break with more wet weather the next week.
