FORECAST:
A cold broad upper trough moves through our zone today with unsettled weather in a Westerly flow aloft. The FL will remain below surface for the entire week. We can expect periods of light snowfall for today. A frontal band will bring overcast skies and light-moderate snowfall to the area Tuesday as the low moves through our zone. Breaks by Wednesday with unsettled weather and the possibility of some intermittent snow flurries. A brief ridge builds for Thursday with sunny skies possible for the morning into the afternoon. A weak front approaches the area for Friday with overcast conditions and very light snowfall. Models are not consistent about the weekend yet but the ECMWF is showing a winter storm by Saturday night, the Nam mostly sunny skies by Saturday. Standby on that outcome.
Guesstimates: 6-10 cm by Tuesday morning, 10-15 by Wednesday morning, 1-4 cm by Thursday morning., trace-1 cm by Friday morning.
