An unsettled weather (forecast) pattern is beginning to unfold over the Memorial Day holiday weekend. A weakening cold frontal boundary may stall somewhere over the region late Sunday or early Monday. This may provide the focus, within a warm and muggy atmosphere, to provide frequent periods of showers and thunderstorms.
The late Sunday through Memorial Day weather pattern of slow-moving clusters of rain and/of storm activity will introduce the threat for both high rainfall rates leading to flooding or damaging thunderstorm winds.
Confidence in Monday rainfall is increasing with lower confidence in Tuesday and Wednesday’s rainfall. Tuesday and Wednesday’s rainfall will be highly dependent upon Monday’s activity.
