Storm Tracker Forecast - Valley Frost Advisory, Then Rain, Snow And Wind Ahead

The small storm which brought a little rain and snow to northern California has already exited the area, and we'll be left with much colder weather Friday morning: Valley Frost Advisory, with heavier rain, snow and wind ahead! We're rapidly losing the clouds we had early today, and everyone will be much colder tomorrow morning. Patchy fog will also be possible. A Frost Advisory is in effect for the valley through 10AM. Tonight will be mostly clear with patchy fog. Lows will range from the 10s and 20s in the mountains to the 30s in the valley and foothills. Friday will be mostly sunny with a few more clouds late in the day. Highs will be close to seasonable, ranging from the 40s in the mountains and foothills to the 50s in the valley. A large trough of low pressure will push southward along the West Coast this weekend. We can expect increasing clouds Saturday with a chance of rain and snow, but much more rain and snow will arrive Sunday and will last through a good portion of next week. A Winter Storm Watch has already been issued for the mountains, lasting from Saturday night through Tuesday night. Lower mountain elevations will receive several feet of snow, with 5-6+ feet possible in the highest elevations. The valley will receive between 2-5 inches of rain through next Thursday. Mountain travel will be discouraged. Prepare for the heavier rain and snow now. Valley lows will be in the 30s and 40s with valley highs falling from the 50s to the 40s.
