    Winter Weather Update- Mon 9 PM
    Tonight's NAM model data has just rolled in. (Those supercomputers keep getting faster.) For PHL airport grid point, the NAM is showing about .55 inches water falling as snow which is about 8-9 inches snow, starting about 6 PM Tuesday and ending by daybreak Wed morning.

    The GFS has been consistent with much lower amounts, about 4 inches. (That's why the commercial Forecasts have been saying 4-8 inches.). The average of 6 inches is most likely.

    The GFS data will be available later.
