A cool upper level trough is moving through the area this am in a Northwest flow aloft. Wet snow is falling in the valley this am. A weak offshore ridge will bring mostly sunny skies by this afternoon, but will be short lived as a strong Westerly flow will bring cloudy skies to the area on Saturday, followed by moist warmer weather Sunday into Monday. The freezing level will rise to above the local peaks before descending on Tuesday as there is a lull prior to some cool Pacific storms rolling through Wednesday into Friday. The FL for this series of frontal waves will slowly drop and we should see some significant snowfall accumulation below mid station. Perhaps we will be getting a taste of an early winter!!

    Moist this am with some breaks on the way.

    Break for today followed by clouds Saturday.

    High weakens and the low will send cloud our way for Saturday.
