Discussion
Quite an amazing outbreak of cold air will arrive on Friday night and the cold frontal passage may actually be accompanied by a rain-changing-to-snow event in part of the Mid-Atlantic region – perhaps even in the higher elevation locations just to the north and west of Route I-95. Saturday will turn out to be a very windy day with gusts possible to 50 mph and an unusually cold day for this time of year with temperatures perhaps 20+ degrees below normal. In addition to the wind and the cold, rain and/or snow showers will be possible on Saturday as the atmosphere will be very unstable given the extremely anomalous upper-level low pressure system that will be sitting right on top of the region. While Sunday, Mother’s Day, will remain colder-than-normal and get off to a very cold start, the afternoon will become much more bearable as there should be far less in the way of wind when compared to Saturday and some sunshine. Looking ahead, the overall weather pattern that has resulted in cold air outbreaks for the central and eastern US in recent weeks finally looks like it may break down during the third week of May.
