   As of 07:00 Hours X-Mas day we have broken cloud and unlimited visibility.



For the forecast, a weak short lived ridge will bring unsettled conditions this am with more sun by the afternoon in a Northwest flow aloft. A weak front will move through on Saturday with very light snow and overcast conditions. Sunday will be similar with a bit more snowfall. Medium range models are in disagreement for early next week so there may be some changes by then. We will likely see a weak ridge for Monday and unsettled conditions for Tuesday in a slit flow. Standby!! The freezing level should hover around the valley with the exception of a brief spike to around 800 meters on Sunday afternoon. Guesstimates: 1-3 cm by Sunday morning, 4-8 cm by Monday morning.


    High pressure building for Christmas Day.

    Low to the Northwest will spin some cloud our way on Saturday into Sunday.

    Low on Sunday has potential for some precipitation.
