More Snow, Hazardous Conditions, for Tuesday Rush

By Laura L Thornton

UPDATED AT 10:30 P.M.—Had enough of the snow this week? 

Well, it's not over yet. The National Weather Service issued a winter storm warning for Montgomery County for Tuesday, from 3 a.m. to 2 p.m. 

Heavy snow is expected, the National Weather Service advised.

Precipitation could start as sleet, particularly south of Montgomery County, and the potential exists for 5 or more inches of snow. Temperatures will be in the upper 20s to lower 30s, with winds blowing out of the north at 5 to 10 miles per hour, the National Weather Service stated in a weather alert.

The snow is likely impact Tuesday’s morning rush with the potential for accumulation rates of 1 to 2 inches per hour over the course of 2 to 4 hours between dawn and mid-to-late morning, the National Weather Service advised.

A snow prediction map from the National Weather Service (posted online by The Washington Post's Capital Weather Gang) predicts 4 to 6 inches of snow for most of Montgomery County, and 2 to 4 inches for the District and nearby neighborhoods to the north.

But, the Capital Weather Gang doesn't entirely agree with the prediction.

"We think this [winter storm] watch may be a bit aggressive and that 5 or more inches of snow is a low probability (not out of the question)," The Gang's Jason Samenow wrote on Monday morning after the watch was issued.

The 5-plus-inches snowfall prediction is a " 'boom' (high-end) scenario," rather than "the most likely scenario," but with the snow slated to fall during the morning rush, it "could have a high impact," Samenow wrote.

The Gang's webpage will keep the region updated.
