Given the small amount of snow we’re predicting, it’s debatable whether a SchoolCast and FedCast is even necessary for this event. But some of our colder areas north and west of town could see just enough snow for a few delays early Wednesday morning.

SchoolCast

The counties that have the highest chance to see delays are in the zone under a winter weather advisory, including Montgomery, Frederick, Howard, Loudoun and Fauquier. We also see a slightly elevated chance of a delay in Prince William County due to the higher terrain and colder temperatures in the western part, and the tendency for that school system to alter operations more easily than do many others.


We actually think counties in Southern Maryland (Charles, Calvert and St. Mary’s) have a somewhat higher chance of a delay than those in the immediate metro region because the snow may last longer there, into the early part of the morning commute. Some computer models also indicate precipitation will be a little heavier east and southeast of Washington.

Overall, however, we wouldn’t be totally surprised if most, if not all, schools open on time Wednesday. The snow will be moving through quickly, ending before sunrise in most areas, and warm ground temperatures will make it hard for it to stick (unless there’s a localized heavy burst). Do your homework …

FedCast

It’s unlikely enough snow will fall for any change to the operations of the federal government. FedCast is provided here simply as a formality.
