    As of 07:00 hrs this am we have overcast skies, variable visability and it is snowing lightly.


FORECAST:

A weak trough in a Westerly flow aloft will bring mostly overcast skies and intermittent snow flurries for today. A strong Pacific front will arrive Saturday night into Sunday with strong winds and moderate to heavy snowfall. The freezing level will hover in the 800 meter range.  The brunt of the energy seems to be heading south but there is some disagreement in the models, more is better. A series of Pacific fronts are slated to push through next week with seasonable temperatures. A carousel of snow producers would be awesome.
Guesstimates:15-30 cm by Sunday morning depending on how far South the front ends up, 30-45 cm by Monday morning, 5-10 cm by Tuesday morning, 15-30 cm by Wednesday morning.
