Friday Winter Weather Update

Latest afternoon model runs maintain the likelihood of snow starting around 8 AM and ending between 6 and 8 PM.

Here are the model trends: Both the NAM and GFS have a QPF of  0.65 inches water equivalent.  The NAM (which did so well with the last storm) has trended colder, with the heavier precip in the afternoon. The GFS is still a bit warmer, but still supports snow.

4 inches  (maybe 5) of snow just outside of the city is likely on grassy and shaded surfaces.  Significantly less on dark asphalt roadways.

With the change to Daylight Savings Time, the next NAM data will become available after 10 PM with final data about 10:40 PM.  The GFS early data doesn’t start rolling out until 11:25 PM DST.  (That’s an hour later for us  than winter forecasts on Eastern standard time.)

I’ll update about 10:45 PM
