Discussion

Surface low pressure has pulled slowly to the northeast over the past 24 hours, but genuine clearing will not occur around here as an upper level trough will linger in the Northeast US for the next few days. This instability will keep alive the threat for showers through tonight and it’ll be just cold enough tonight for the possibility of a snow shower. A gradual “step-down” cooling trend will begin today and continue through the weekend so that by Sunday our highs may be confined to the mid and upper 30’s (normal high is now 47 degrees). This weekend's cool shot will make it all the way down to Florida where spring training fans and spring break travelers will need sweaters and jackets. Looking ahead, low pressure could affect the Mid-Atlantic region by the middle of next week as an overall active weather pattern continues.

Finally, in the video I point out a forecast map for Sunday morning that features the strongest high pressure system that I've ever seen. The pressure over Greenland actually reaches 1092 millibars (32.24 inches) in this NAM model forecast for Sunday which, if accurate, is a sign that some very dense, cold air remains in the northern Hemisphere despite the turn to March that begins on Friday.
