A warm front with a trailing cold front will push through today in a Westerly flow aloft. The FL will slowly fall from 1500 meters this am to around 1000 meters by tonight. We can expect an increase in cloud cover with some periods of light snow today, with an impulse of moderate snow tonight into Saturday morning, depending on how the cold front tracks. The front will switch to a dry upper level trough for Saturday with periods of light snow in the morning, becoming unsettled in the afternoon with a ridge of high pressure bringing clear skies by Saturday night.  The FL will rise to 1500 meters on Saturday. The ridge builds Sunday with mostly sunny skies and warming temperatures. The FL on Sunday will reach 1800+ meters with a trend to reach 3800 meters by Wednesday. No change expected until next Thursday.
Guesstimates: 5-15 cm by Saturday morning, 1-3 cm by Sunday morning, 0 cm expected Monday thru Wednesday. Sunscreen will be needed!!!
