March 17 – The luck of the Irish may be helping the Maryland thaw but not Pennsylvania. A warm front ahead of a Mid Wester Low Pressure will arrive this evening. There may be some sleet and snow mixed in with some rain this evening, but warming should take over. But near and especially north of the boarder in PA, colder temps will allow for some icing to develop. The Winter Weather Advisory includes Adams, York, and Lancaster Counties and northbound. Deeper snow pack and colder air, plus the rugged hills and valleys will help the cold hold longer.

Some roads and sidewalks could get icy overnight and into Saturday morning. While the Advisory lasts until 11 AM, I think most areas should be fine just after sunrise. It will be a quiet day, then were watch the second part of this system drag down colder air Saturday night. This is when snow will return and extend southward into Maryland. If you have plans late Saturday night or Church plans early Sunday, this could play a role in your travels. See the Maos below.

A secondary Low will form with this pattern. It will drag in colder air and bring in snow Saturday night into Sunday. Notice the last few maps and where the freezing line is. I expect there will be some accumulation and some road problems… but it would be hard to get more than 1 inch out of this.  At this point, the snow may may be briefly moderate in Harfrod, Cecil and Kent Counties in Maryland… and northern Delaware to Philadelphia. Just consider a slight delay for your plans.
