The latest radars show that the heavy rains that fell over much of central New Jersey and parts of northern New Jersey have moved away offshore. The spotty showers over Hudson Valley and Long Island will last a bit longer, but the rains will be pulling out soon, leaving us with lots of low clouds and an onshore wind Sunday night. This is going to make for rather raw, damp conditions for the rest of Sunday with temperatures settling into the upper 50s and lower 60s in most areas.
The frontal boundary lies across southern New Jersey and southeastern Pennsylvania, where temperatures were in the 70s at midday and winds have not yet shifted around to the northeast. Another downpour or thunderstorm is possible here, with some highs reaching 80.
The boundary line to the south might produce a few showers overnight in central and south Jersey. Memorial Day looks to be on the cloudy side with the risk for passing brief shower but skies could brighten up in the afternoon as dry air begins to move in from the northwest. Temperatures should be able to reach into the 70s. This will lead to sunshine and rather warm conditions on Thursday with highs reaching into the 80s.
