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.

Fairly significant changes in the large scale weather pattern may occur over the next 7 to 10 days.  Map 1, below, shows the upper air weather pattern for today.  The jetstream is to our north.  This means just the southern end of the storm systems brush Northern California.  Map 2, below, shows the upper air weather pattern for next Tuesday and Wednesday.  There is a strong jetstream running across the Pacific and right over Northern California.  This means the main part of the storms would affect our area.  We will have low pressure troughs and frontal systems moving through the north state every couple of days.  The systems start out fairly weak but will become better precipitation producers by next week.  

The first front comes through tonight and early Thursday with light precipitation and snow levels 3500 feet north and 4500 feet south.  Thursday night and early Friday there will be a break and then another weak system will move through late Friday and Saturday bringing light rain or showers our area with snow levels near 4000 feet.   Saturday afternoon and part of Sunday look partly cloudy to cloudy with the chance of showers.

A stronger storm will move in Sunday night and Monday and then a stronger system Tuesday night and Wednesday. Snow levels look to be about 4000 feet north and higher south.  Gusty south winds will precede these storms.
