Wintry Weather Expected on Friday

Here is an update on the potential snowfall expected for Friday morning.

Our updated snowfall map calls for a possible dusting for areas NW of I-95. This, if verifies, would only accumulate on the grass and car tops. There will be no accumulation on the roads or sidewalks. For areas north of I-70, especially across the MD/PA state line, the Catoctin Mountains, and southern PA, 1-1.5 inches seems possible, with perhaps an isolated 2" total somewhere. Even here, paved surfaces will likely remain just wet, with accumulation being confined to grass and car tops. We expect no travel impacts to the Friday morning commute. The only exception to this would be up in northwestern Frederick county along the crest of the Catoctin Mountains. Its not out of the question that they stay colder longer, and wind up with 2-4". But that's not an especially likely scenario. If that did occur, some minor slushiness would be possible on especially backroads in that area. 

As far as timing goes, it has been pushed back a touch, starting in southern PA and northern MD between 4am and 7am. Areas along and just south of the I-70 corridor can expect snow to start between 6am and 9am. And if it happens to reach any further south than that, start times would be after 9am.

This will likely be our final call, as we do not anticipate much to change with this winter weather event. However, we will continue to monitor things and update if needed.
