Original post, 6:52 a.m.:

Snow and rain have moved out of the area, but cold temperatures are creating icy conditions on many Washington area roads.

Two accidents on northbound I-270, near Montrose Road and Tuckerman Lane in Maryland, may be due to icy conditions. Patchy ice has also been reported on Rockville Pike in North Bethesda and parts of Patuxent Freeway (MD 32).

Patches of black ice are a hazard for drivers and pedestrians alike, especially in areas north and west of the District where temperatures are at or below freezing this morning.

The Capital Weather Gang predicts that temps will rise to the mid-40s, but light rain and snow showers are not out of the question.
