Gusty Storms, Flooding Possible in the Northeast

27 Aug 2021, 3:55 pm

With highs in the 90s, plenty of tropical moisture and upper level energy in place across the Northeast, there is a risk for severe thunderstorms with damaging winds this afternoon and evening. Storms will be isolated, but slow moving with wind gusts of 60 mph possible. The slow moving nature will also allow for flash flooding to occur in spots.

Forecast

Rain and thunderstorms are expected to continue into the evening. A frontal boundary meeting up with a hot and muggy airmass will allow for storms to develop quickly.

Toward the end of the evening, energy is forecast to diminish. Storms as a result should wind down, but a few may persist overnight.  Heavy rain will become the biggest threat but isolated 30-40 mph gusts will be possible with the strongest storms into Saturday morning.

Rainfall

Slow moving thunderstorms will continue on Saturday as energy near the front lingers and tropical moisture pools to the south. Flooding will be possible in spots where thunderstorms train over the same areas. Torrential downpours leading to urban flooding, flash flooding and river flooding are expected.

Excessive Rain Outlooks have been issued to account for the flood potential today and tomorrow. Darker green colors indicate increased chance for flooding.

Widespread rain totals should be around 1″ for most of the region, but isolated amounts of 3-6″ will be possible where the heaviest and nearly stationary downpours set up. The location of the heaviest rain could change but with tropical moisture in place rain rates could exceed 1-2″ per hour.

Heat

Heat alerts are in place for dangerously hot and humid conditions for highlighted areas. This includes the New York City metro, where heat indices could reach 100. Highs will be in the upper 80s and low 90s but high humidity levels will make it feel much hotter.

Today will be the last of the heat alerts as cooler air moves in behind the cold front tomorrow. However, the heavy rain threat will persist tomorrow near the front.
