Most of the showers have tapered off across Northern California but there is still some scattered shower activity lingering in portions of the foothills and Sierra this evening. Fog was a factof for your morning commute today and is expected to be an issue for drivers again late tonight and early Tuesday. Visibility issues are expected to be the biggest impact to travel on Christmas eve but the fog should clear out by mid to late morning. Temperatures will become chilly overnight tonight. Valley areas will dip into the high 20's to mid 30's, and mountain areas will end up in the teens to 20's tonight. Mostly mild weather is expected for your Tuesday. Skies will start out mostly clear but will become mostly cloudy for your afternoon. There will be a chance for some showers as early as tomorrow evening, but that does not look very likely at this point. High temepratures will end up in the mid 40's to low 50's in the valley on Tuesday afternoon, and mountain areas will mostly end up in the mid 30's to low 40's.

Rain and snow showers are expected to return to Northern California late Tuesday night, and then spread through all of our region on Christmas Day. Snow levels will be down to as low as 2000' on Tuesday night, but will lift to around 3000' to 3500' on Christmas morning. Temperatures will be warmer for the morning on Wednesday, but slightly cooler in the afternoon. Showers are expected to be light. Valley areas could potentially see up to a half an inch of rain, and mountain areas could see a few inches of snow. Those estimates are a little high for this fast moving system. We'll be drying out again for your Thursday forecast, and skies will be sunny. Dry and mid weather will conitnue on Friday and last into your Saturday. Temepratures will not change much during that time. Low temperatures will end up in the low to mid 30's in the valley and in the teens to 20's in the mountains. High temperatures will top out in the mid 50's in the valley for the end of the week, while mountain areas end up in the 30's to 40's.

There will be cloudy skies and the potential for wet weather returning as we head into your Sunday forecast. The chance for showers on Sunday is currently sitting at around 20 percent. Temperatures will become cooler for the latter part of your weekend. Monday currently looks to be dry, mostly sunny, and a little warmer than Sunday.
