General Discussion: As anticipated, a strong warm front with a significant amount of moisture will lift north through the state today. This will bring snow changing to rain for the next 24 -36 hours.
Long-term: The faucet is expected to turn off late tomorrow evening. The silver lining is that a nice looking winter storm, with cool NW flow, will slide in on Tuesday bringing back the snow.

Storm totals look like this: .75-1” by midnight tonight – possibly +12” of snow depending when the east flow gives in.
