Update- Sunday night
The NAM and GFS have come together tonight with about 0.08 inches of water (QPF)falling as snow tonight. This translates into about 1 inch or so.
Temperatures will be dropping considerably. Expect icy conditions in the morning, even with a coating to an inch of snow.

Update- Sunday Afternoon
Once again, there is low confidence with the forecast, because the GFS and NAM disagree about rain/snow for us this afternon and night and neither correctly captures the precipitation on radar this early afternoon.
The GFS is predicting nothing, while the NAM-WRF is showing about 1 inch of snow tonight. I wouldn't hang my hat on either solution, but the radar trends suggest that the NAM may be underestimating the potential for 1-2 inches and the GFS is certainly missing the boat.

Sun 1/28: Cloudy the balance of the afternoon, with light rain showers possible this afternoon, changing to light snow this evening. Possibly 1 inch of snow potential by Monday morning, although confidence in this forecast is lower than usual.
