The snow is all but over in the Washington area, but temperatures will drop tonight, posing a risk for icy roads by the morning commute.

We suspect the road crews will be able to handle the main thoroughfares, getting them into good shape by tomorrow morning. The side roads and sidewalks, on the other hand, will probably be icy, especially in our north and west areas where temperatures will be coldest. For that reason, we’re predicting a pretty high chance of delays for places such as Montgomery and Fairfax counties.

The other notable thing in this SchoolCast is our far southern and eastern areas have a much higher chance of closing than they usually do. St. Mary’s and Calvert had five inches on the ground as of late afternoon Wednesday. Annapolis was up over six inches at that point, and it was still snowing there.

At any rate, take it easy on the side streets tonight and tomorrow morning. Conditions will improve after the sun comes up. Temperatures should be above freezing by 9 a.m. in the Beltway and 10 a.m. in the colder suburbs.
