Wednesday December 13

The clipper on the move will arrive with some flurries and snow showers by evening. The tricky part of this forecast is plotting a fast moving upper level storm that is expected to track right along the Pennsylvania and Maryland line. This puts the classic ‘north and west’ pattern into play. You know the areas that often are colder and get more snow… That is where this is likely to snow. The hourly plots from the radar simulation are blow.

This snow is only going to amount to a coating, maybe up to 1 inch in spots. But most of us stay below freezing today while wind chills struggle to get out of the teens. The ground is sufficiently cold for stockage. The timing may impact some late day school/sport activities, but should be done overnight. WE could get some leftover snow flurries to spread farther in the morning, but no accumulation expected.

This area this evening includes the western Maryland mountains through Frederick, maybe near Mt Airy, then northern Carroll, Baltimore, Harford, and Cecil Counties… plus most of Pennsylvania.

If this has tracked a little south, along I-70 then that would have put more of metro Baltimore into play. But the topography plays a role in where the snow will want to go.

The main light snow will be north of I-70, but flurries or a light shower could fall across the rest of the region. Temps will be above freezing near the Bay and eastward.
