Forecasters are calling for a third wintry weather system to pass through Baltimore in less than a week to drop 1-2 inches across Baltimore and areas close to the water, with 2-4 inches further inland, according to the National Weather Service.
Carroll, Harford, Howard and northern Baltimore counties are under a winter weather advisory from 3 a.m. through 6 p.m. Saturday, issued by the weather service's Baltimore/Washington forecast office. The advisory could later be extended southward, but as of Friday morning, there was still disagreement in forecast models predicting where the rain/snow line could fall, according to a forecast discussion.
While snow could fall throughout the day in northern and western parts of the state, to the southeast, temperatures are expected to warm enough for rain to mix in with the snow during the day, according to the weather service.
Chances of a more significant snowfall appear to have waned, according to the weather service's Hydrometeorological Prediction Center in College Park. Chances of at least 4 inches of snow are smaller than 10 percent in most of the state, whereas forecasts Thursday called for up to a 70 percent chance of at least 4 inches of snow in some parts of Central Maryland.
AccuWeather.com's Henry Margusity writes that 1-3 inches are possible on the northwest side of Interstate 95. Former TV meteorologist Justin Berk is more bullish on the storm, calling for at least 3 inches for Annapolis, Washington, D.C., and points north.
Foot's Forecast predicts 2-4 inches across most of Central Maryland, also including as far south as Annapolis, with an inch farther south.
State Highway Administration crews started pre-treating roads in Montgomery, Prince George’s, Baltimore, Harford and Cecil counties Friday morning with a liquid salt brine solution to prevent freezing. Administration officials expect the storm to reach the Baltimore area between 6 a.m. and 7 a.m., winding down between 3 p.m. and 4 p.m.
“Fortunately, in many areas of the State, we are ahead of the game because there is still salt on the roads from our applications earlier in the week,” SHA Administrator Melinda B. Peters said in a statement. “We will supplement where necessary, and our plow operators will be standing by ready to begin clearing as soon as the storm starts tonight.”
The storm is likely to make this winter already the snowiest in two years (which isn't saying much). An inch of snow fell at Baltimore-Washington International Thurgood Marshall Airport on Wednesday; 0.8 inches more is needed to match the paltry snowfall total at the airport for winter 2011-2012.Copyright © 2015, The Baltimore Sun
