Assignment: Predict the 24 hr minimum temperature (deg F) for Bangor, ME (KBGR)

Tuesday should be an active day in Maine, with snow early in the day, changing to rain later. The MOS forecasts from the two main U.S. numerical models, GFS and NAM, are mostly in agreement, except that the GFS MOS has Tuesday morning low temperatures about 10 F colder than NAM MOS for many sites in Maine. So let's predict Tmin for Bangor and see which model gets it right.

What Happened?

The low in Bangor ended up at 13, so between the GFS and NAM MOS predictions. They gradually moved toward each other for the more recent runs.
