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.

The low pressure area approaching the Pacific Northwest will brush Northern California later today as it drops southeastward.  Not much moisture for our area but there will be a few light showers over the higher elevations late this afternoon and tonight.  Snow levels will be 5000 to 6000 feet.  

Skies will be clear by Tuesday morning with mostly clear skies through Thursday afternoon.  Temperatures will be above normal.  Gusty north winds will occur in some areas Tuesday with light winds Wednesday and Thursday.

Clouds start increasing Thursday afternoon.  Friday a low pressure trough will extend from the Gulf of Alaska to off the west coast (see map below)..  This will drop the jetstream over Northern California and open the door for frontal systems to move through.  The first system will bring rain to the north state Friday with another storm due in Sunday and Monday.  Snow levels with the Friday storm will be near 5000 feet but lower with the Sunday storm.
