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 still over the western U.S.  However, changes in the large scale weather pattern are beginning.  Over the next 5 days the high pressure ridge will shift westward and be off the coast.  Northern California will still be mostly sunny with a few clouds from fronts passing by to our north.  Temperatures today will be 12 to 16 degrees above normal but will slowly cool to near normal by Saturday.  Gusty north will occur today then decrease Tuesday morning, but then increase again Wednesday.  The north winds will end late Thursday.

Late Saturday the jetstream will sag southward and this will allow a low pressure trough to move through the area Sunday (see map below).  This trough will bring light rain to the north state Sunday and early Monday.  Snow levels will start out high by lower to 5000 feet by Sunday afternoon.
