The Winter Storm Warning is in effect until 10 a.m. on Tuesday morning and replaces the Winter Weather Advisory that had previously been in effect.
Total snowfall and sleet accumulations (including snow that has fallen since Sunday night) of 3 to 7 inches are now expected, with isolated totals up to 9 inches possible along the Pennsylvania border in northern Baltimore and northwestern Harford Counties. Freezing rain accumulations of a tenth to a quarter of an inch are also expected through Tuesday morning.
The Winter Storm Warning covers north central and northern Maryland and Morgan County, West Virginia.
Travel may become extremely difficult, especially north of I-70 to near the Pennsylvania border. These conditions will likely affect the Tuesday morning commute. The combined weight of snow, sleet, and freezing rain
will likely result in scattered power outages.
A Winter Storm Warning means significant amounts of snow, sleet, and ice will make travel very hazardous or impossible.
