Discussion

A strong “clipper” system will drop southeastward on Friday across the Great Lakes and into the northeastern part of the nation and it’ll create lots of instability in the atmosphere around here. At the same time, the southern storm that continues to produce significant rainfall in the southern states will intensify as it moves off the east coast and out over the western Atlantic. While this storm will be well off the east coast by late Friday, there can be an inverted trough (aka “norlun” trough) extending from the low pressure center all the way back to the Mid-Atlantic region which will also contribute to some instability in the atmosphere. The combination of the “clipper” system and the inverted trough is likely to lead initially to rain on Friday and then some rain and/or snow is likely on Friday night with small grassy accumulations possible. The weekend will start off on the chilly and dry side, but a big time warm up will take place early next week. In fact, Monday will turn out to be a "spring fever" alert type of day with sunshine and afternoon highs in the 60's.
