Forecasters are predicting some snow accumulation around the Baltimore area Saturday, but just how much and how far south it could fall will remain somewhat of a mystery for perhaps another day. As of Thursday afternoon, though, it was looking like a snowy Saturday is likely.
Models are suggesting a storm system will move up from the Gulf Coast through the mid-Atlantic to the Northeast over the weekend. But they are still mixed on what type of precipitation will affect Maryland.
"Our corridor, the mid-Atlantic, is typically where the rain/snow line sets up, and this storm is no different," said Nicole Listemaa, a forecaster with the National Weather Service's Baltimore/Washington office in Sterling, Va.
"The models we have that help us try and resolve these issues, there’s a lot of difference between the solutions right now," Listemaa continued. "Some models are cooler, some models are right in between with more of a mix, and some models aren't predicting much of an impact at all."
A clearer picture of how the system is expected to behave could come late Friday, she said.
The weather service's Hydrometeorological Prediction Center in College Park expects a 40-70 percent chance of at least 4 inches of snow for the northwestern parts of Central Maryland, including parts of Baltimore, Carroll and Howard counties. Further south, forecasters expect at least a 10 percent chance of that much snow along the Interstate 95 corridor.
The local weather service forecast office is calling for 2-4 inches for Carroll County and across northern parts of Baltimore, Howard and Harford counties, with 1-2 inches further south, including Baltimore City and nearly all of Anne Arundel County.
WBAL-TV's meteorologists suggest that, given the surprise snow accumulation in the previous two storms, models showing heavier snowfall across Maryland may deserve more credence. That could mean 1-3 inches of snow as far south as Calvert and Somerset counties, with 3-6 inches in northern Carroll and Baltimore counties possible.
More cold air could be in place than with previous storms come Saturday, according to WJZ-TV's Bernadette Woods. Models are in agreement that the precipitation will at least start off Saturday morning as snow, according to the other Maryland Weather blog.
AccuWeather.com's Henry Margusity predicts 1-3 inches of snow on the northwest side of a line that could fall 10 or so miles south of I-95, placing the snow's reach into northern Anne Arundel County and across Harford and Cecil counties.
Foot's Forecast does not expect the storm to intensify like Wednesday's, but predicts it could still drop 2-4 inches of snow across Central Maryland.
