A tricky forecast the next few days. We are in a colder pattern with a weak low pressure area moving across New England. Some cloudiness along a trailing cold front will come in later today and overnight. Enough moisture with the front that there may be some snow flurries across northern Maryland and near the Blue Ridge but the primary impact will be some reenforcing cold air over us before another wetter storm forms and moves near us Saturday. The cold dry air at the surface but with milder, moist air above us sets the stage for the dreaded "wintry mix" coming in Friday night into Saturday. As happens in these situations, the cold air will "stick" around to the north and west of DC and especially in the Shenandoah Valley. That cold air damning means any snow falling Friday night after midnight, will change to sleet and then freezing rain. Even in the immediate DC area you should expect to see ice by Saturday morning. This is not a big storm but with no strong push of mild air at the surface, the freezing rain or drizzle is likely to persist into Saturday afternoon. Sunday right now looks just cloudy and cold. More updates from the team as this situation becomes clearer.
