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 weather across Northern California is quite varied today. This morning's satellite picture (below) shows the sub tropical moisture streaming northward into the Pacific Northwest. The northwest corner of the state is cloudy with rain. The valley has locally dense fog which will burn off in the next few hours. The rest of the state is partly to mostly sunny.
Thursday a weak frontal system will move across our area with clouds and a few showers. Snow levels will be high. Friday there will be a brief break, but clouds will increase Saturday as a low pressure trough approaches the coast (see map below). Rain will spread over the area during the day and continue through Sunday. Snow levels will start out at 6000 feet or higher but will drop to 4500 to 5000 feet by Sunday afternoon.
Skies will be clearing Monday with mostly sunny skies and slightly above normal temperatures expected Tuesday and Wednesday.
