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 south end of a frontal system is brushing Northern California this morning with clouds and isolated showers near the Oregon border. 

Tuesday things get interesting.  It now looks like the cold low pressure area will rapidly intensify as it approaches Northern California.  This will make the storm wetter and windier.  Clouds will increase Tuesday with precipitation spreading southward over the north state during the afternoon and evening.  Snow levels will start out at 500 to 1000 feet from Redding northward and 2000 to 2500 feet in the Tahoe area.  Snow levels will rise up slightly Tuesday night and early Wednesday.  Winds will increase Tuesday afternoon with wind gusts to 60 mph in the north end of the valley and 70 mph over the higher elevations Tuesday night.  The low will be over Northern California Wednesday (see map below) and will be moving eastward.  The precipitation will turn to showers by Wednesday afternoon.  The winds will decrease by midday Wednesday.

Thursday we will have partly cloudy skies with showers over the foothills and mountains with a chance of an isolated shower in the valley.  Snow levels will continue low. 

Friday looks mostly sunny and cool and then another low pressure area will spread more rain over the area late Saturday through early Monday.  Due to cold trapped air the snow levels could be low in the north end of the valley.
