3:30 PM: Heavy Rain Moves In
Earlier this afternoon, widespread heavy thunderstorms formed over interior SE NY, and are very slowly moving SE into the northern and western parts of the area. A few storms could be strong or low-end severe, with gusty winds and small hail possible, but for the main part little severe weather is expected, with heavy rain the bigger risk.
Due to the slow motion of the storms along with high precipitable water values, flash flooding is expected in some areas north/west of NYC, with amounts exceeding 1-2 inches in some areas. The storms will also get into NYC and Long Island, although the highest rain totals are expected to stay north and west of NYC.
A forecast discussion will be posted later this afternoon, including more information on the additional rain expected for this upcoming week.
