Don't put the snow shovels and sidewalk salt away yet.

Had enough of the snow this week? 

Well, it's not over yet. On Monday morning, the National Weather Service issued a winter storm watch for Montgomery County for Tuesday, from 5 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 mph, the National Weather Service stated in a weather alert.

"The snow will likely impact the morning rush Tuesday with the potential for accumulation rates of 1 to 2 inches per hour," for 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.

"A winter storm watch is issued when there is the potential for significant snowfall and hazardous winter weather within 48 hours," the National Weather Service stated.
