3:45 PM Tuesday Update

Steady snow, and in some locations, moderate to heavy at times, will continue across central Maryland into the evening hours. Roads are already becoming slush covered in many areas and will continue to deteriorate. Once temperatures fall below freezing early this evening, any untreated surfaces will freeze very quickly. Temperatures will stay below freezing throughout the night and icy conditions will persist into the morning especially on side streets, sidewalks, ramps, and bridges.

During the day tomorrow, models show that an intrusion of arctic air will be preceded by a snow squall. Timing looks to be around noon, and if you’re out during this time, expect a period of very heavy snow, high winds, and extremely reduced visibilities. I’ll send an update out tomorrow morning on the expected intensity and timing.
