December 11 2019

Early Report: The snow has fallen overnight and left a coating on the grass for many. While roads have appeared wet in most areas, there have been reports of icy spots in the colder counties. The concern is that a few hours of temps near or just below freezing can still allow untreated wet pavement to ice up.  The temperatures are reported at 5 feet above the ground. The surface can be a little colder… Just be aware that there cold still be some icing.

Final Burst of Snow

Harford and Cecil Counties made the call to delay schools last night. They have snow this morning, so this will put a lot of parents (and teachers) at ease.  The wet versus icy road set up is spotty. As temps continue to remain near or drop below freezing, the chance for ice to develop remains through 8 AM. But this is the final burst of snow.

Eastern Shore getting a moderate clip of snow and their coating to 1 inch.  The best chance for any icing on roads will be away from the water of the Bay. Snow showers through mid morning.

Forecast Temps

This afternoon





Ravens Game: It will be chilly (in the dark of night) at the stadium, Prepare for temps near or below freezing in Baltimore.


Looking Ahead:

  • Rain returns Friday evening and will be heavy into Saturday morning.
  • The Army Vs. Navy game in Philadelphia should get a break in the rain with mild temps, but it will be windy.
  • The next even could bring inland ice or snow Monday into Tuesday. Remember that models have been slow with long range…. So This timing could speed up a little and change the dynamic of where it could be icy or wet.
