Week Ahead Brings Shower Chances Late Tuesday & Again Late Week
This Sunday is going to be a day of no worse than partly sunny skies. We have an onshore flow to deal with and that is going to keep temperatures in the lower 70s for the most part for highs. Along south and east facing shorelines like Long Island and the New Jersey shore, temperatures will be in the 60s. We are seeing some clouds in the Mid Atlantic and that is due to the onshore flow but that moisture should remain pinned to our south with no weather issues expected from this. Radars may show a few showers developing later today in the Central Appalachians but that’s where they will stay.

Another night of 40s and 50s looms under mainly clear skies though there may be a few clouds across southern areas of New Jersey and Pennsylvania. Monday promises to be a partly to mostly sunny day and we will see temperatures warm up a bit. We will have more of a south wind and that should allow inland temperatures to reach the mid to upper 70s but it will be cooler again along the coast. Autumn will arrive and we officially close the boo Summer 2025
The one important change in the pattern this week is that we are going to so finally see the Atlantic and Gulf of Mexico available for moisture and weather systems will be able to take advantage of that. A cold front will approach Eastern Pennsylvania and Upstate New York Tuesday with some showers and thunderstorms and we expect to see those showers and storm move east to Southern New England and Long Island.
The front will pass to the east and then stall out as energy dives southeast from Central Canada and into the Ohio and Tennessee Valley. This creates another wave that will head into the Eastern US with a north south frontal boundary and with it, the risk for rain and some thunderstorms late in the week. It should be noted that some models are taking a tropical wave which as of today is in the Eastern Tropical Atlantic and making it into a tropical storm of some sort off the Southeast US coast. The upper air set up is such that if that were to happen it could possibly be an issue. However while all models have a similar upper air set up, they all differ on whether this tropical system will develop at all. It is a bit of a wild card in the forecast outlook for the time being and we will monitor the situation carefully as we move through the new week.
Ahead of the front Tuesday it will be a warm day with partly sunny skies to start and highs reaching the lower 80s in many locations. Then showers and some thunderstorms arrive. The Storm Prediction Center is not indicating severe weather risk at the moment. Once the storms pass Wednesday looks to be a dry day before the risk for showers and storms revs up again for Thursday and Friday.
