I expect a virtual "rinse and repeat" of this sequence on both Saturday and Sunday, except that highs will only be in the low-to-mid 50s Saturday and around 50 on Sunday. The core of the coldest air will settle over the mid-Atlantic from Saturday evening through Sunday afternoon, so don't be surprised to see some graupel or wet snowflakes mix in with the rain showers. We've already seen this happen a few times under similar conditions during the past 2 weeks, so there's plenty of reason to believe it will happen again this weekend. When disturbances combine with temperatures that rapidly decrease with increasing height above the ground, graupel (or "soft hail") is actually quite common. Graupel is simply a form of precipitation that occurs when supercooled water droplets accumulate and freeze on falling snowflakes. Add in gusty, west-to-northwesterly winds of 10-20 mph on Saturday and 20-30 mph on Sunday, and we'll have the "full course meal" of miserable weather conditions for the entire weekend (yet again ☹️). Low temperatures on Saturday night will drop into the 30s, and I'm growing more concerned about a widespread frost or freeze early Monday morning. The large-scale trough will gradually lift into northern New England and the Canadian Maritimes Sunday night into Monday, allowing an area of high pressure to build into the central Appalachians and southern mid-Atlantic region. Clearing skies and diminishing winds will create the ideal setting for radiational cooling Sunday night -- hence my concern for lows around freezing (32 degrees F) Monday morning.
