FORECAST:

An upper level trough with a weak cold front will bring periods of light snow for today in a Westerly flow aloft. The freezing level will rise to around 1000 meters. A series of weak Pacific frontal bands will bring periods of light snow into Friday. As of now Friday night into Saturday looks to be the biggest precipitation event with 15-25 cm, still too early to get an accurate amount. Wednesday is looking like the nicest day this week with sunny breaks around noon as we get some weak ridging. A weak warm front for Thursday will bring more light precipitation. Another weak ridge for Friday with unsettled weather, before a more vigorous cold front arrives Friday night into Saturday.
 Guesstimates: 2-6 cm by Wednesday morning, 2-5 cm by Thursday morning, 4-6 cm by Friday morning.
