FORECAST:

A weak frontal band and associated low will leave the area this am with some lingering flurries and a drying trend. A Northwest flow aloft will gradually bring some cooler air into the area with the FL dropping to surface by tonight. For today we can expect some breaks in the morning with some intermittent snow flurries. Unsettled for most of the day with increasing breaks this afternoon. The arctic front will bring some cooler temperatures to the area Friday, some lingering cloud likely in the morning with sunny skies in the afternoon. This pattern will continue into next week with a mix of sun and cloud. The FL will remain near the surface Friday then bounce up and down over the weekend with it dropping to surface in the evenings and hovering at around 1200 meters with day time heating.
Guesstimates: Trace-1 cm for today, no snow after that until sometime next week depending how the high and arctic front react. Models are not agreeing with respect to next week. Standby.
