Discussion
A heavy rain and flooding event is likely for the region from Wednesday into early Thursday. The remnants of Ida will push into the Mid-Atlantic region on Wednesday and its associated rainfall shield will actually tend to become “re-invigorated” and broaden out as it encounters a stalled-out frontal boundary zone and an upper-level jet streak. A general 2-4 inch rainfall is likely in the NYC metro region from later tomorrow into early Thursday and isolated higher amounts of up to 6 inches are even possible. Thunderstorms can mix into the picture and - as is somewhat customary with tropical systems in the middle latitudes - isolated tornadoes will be a threat to the east of the storm track. The greatest threat for severe weather during this storm will take place across southern and central New Jersey. Cool air for the beginning of September will follow the departure of the tropical storm with highs in the late week and early this weekend confined to the 70’s in much of the NYC metro region.
