1/2 An #Arctic cold front will traverse northern MD, southeastern PA & the LSV between ~3-9 AM Thurs. & be accompanied by an intense line of rain/snow showers. A coating of #snow is possible on grassy surfaces, especially N/W of Route 15/I-81. Temps will drop behind the front..
2/2 .. but roadways shouldn't turn icy due to temps >32°F ahead of the boundary & partial sunshine behind it. There may be slick spots on secondary roads in the South Mtn Range & N/W of I-81, but a brief/sharp reduction in visibility within the squall line will be the main issue.
