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.

Quick update this morning...The discussion below still pretty good on timing and the fact that we are entering a very wet patten.   The fly in ointment is once again "trapped cold air".  It now looks like the precipitation for the first system will start sometime after midnight.  Snow levels from Redding north will start out at 500 to 1000 feet and there could be several inches of snow down to that level before the cold air is broken up.   Snow levels still expected to rise to 5000 to 6000 feet Saturday night.  I will update this blog late this afternoon or this evening.

The low pressure area and frontal system are slowly moving east.  Today the north state will see partly cloudy to cloudy skies with showers, mainly over the higher elevations.   Snow levels will be 1500 to 2500 feet north and 3000 to 3500 feet south.  The showers will end by evening and skies will be clearing.  Thursday and most of Friday Northern California will be partly to mostly clear with light to moderate north winds.   

Clouds will begin increasing late Friday as a low pressure trough develops off the coast.  This trough will be along the coast Saturday and Sunday (see map below), during this time the north state will see periods of moderate to heavy precipitation with snow levels rising to 5000 to 6000 feet by Saturday afternoon. night.  Gusty south winds will occur Saturday and early Sunday.  

Monday we will see a brief break as the low moves east.   However, by Tuesday another low pressure trough will be along the coast and this system will bring more rain to our area Tuesday and Wednesday.  Snow levels will be 3500 to 4500 feet.

The 7 to 10 day forecast models continue a wet pattern for Northern California with more low pressure troughs expected to move through.
