I can not tell how the roads will be since that depends on your local crews. But untreated roads, sidewalks, and parking lots will be slick.

  • Less snow
  • Still icy morning
  • Gradual thawing through noon, lasting longer north of Baltimore.
  • The later expiration for Maryland Counties does not mean it will thaw sooner in southern PA. I know it can confuse people who live or travel between these areas, but it is just the lack of coordination between NWS offices.
