Severe Thunderstorms Possible In The Mid-Hudson: NWS

HUDSON VALLEY, NY — A hazardous outlook has been updated for Dutchess and Ulster counties even as the threat of storms diminishes for the lower Hudson Valley and utility companies work to repair scattered outages.

The National Weather Service's Storm Prediction Center has placed the mid-Hudson in a marginal to slight risk for severe thunderstorms pretty much all day Tuesday, with the highest probability for storms in the afternoon.

The main hazard from any severe thunderstorm is damaging winds. There is also a marginal risk for excessive rainfall today due to heavy downpours from storms that may result in localized poor drainage or urbanized flooding.

Orange, Putnam, Rockland and Westchester are no longer under a hazardous outlook.

Scattered power outages existed Tuesday morning, with the most in Westchester County, where Con Ed reported 350 customers out at 8:15 a.m., most in Fleetwood.

"Once the upper level low exits... things will improve dramatically. By Wednesday, a good deal of sunshine with low humidity... and highs around 80°. Then a flow out of Canada will usher in some of the coolest air we've seen since spring," Alex Marra and Bill Potter of Hudson Valley Weather said on Facebook.
