Significant snow unlikely Sunday night, forecasters say

Baltimore area residents can expect some precipitation, possibly including small amounts of snow, overnight Sunday, with the greatest likelihood of wintry weather occurring in the predawn hours Monday, according to Greg Schoor, a meteorologist with the National Weather Service in Sterling, Va.

"We're expecting a mix of snow and rain in periods [overnight Sunday]. We don't have an official prediction on accumulation at this point, but our current track of thinking suggests it would be light in both the Baltimore and Washington, D.C., areas," said Schoor, who was monitoring conditions early Friday evening.

According to current NWS weather models, there's a 70 to 80 percent chance of precipitation in Baltimore City and surrounding counties late Sunday and into Monday.

Earlier forecasts had called for likely snow. Meteorologists are now expecting temperatures to hover in the mid- to upper 30s during the period, though, meaning the storm front will mostly take the form of rain in central Maryland.

"This looks similar to the pattern that happened last weekend," Schoor said in reference to a prediction that a cold front would move through Maryland last Sunday.

This weekend's storm has its origins in a weather system expected to drop about 6 inches of snow from Colorado to Ohio and to retain enough force to deposit perhaps a foot of snow on portions of the central Appalachians late Sunday and into Sunday night.

Schoor said warm conditions over the Chesapeake Bay could change things before Sunday night and Monday, but that any effects would likely be manageable.

"Sometimes [weather systems] do slow down and drop a band of snow in the wrong place. We'll keep monitoring that," he said.
