Severe weather NYC: Impacts

What we know:

Much of New York City should expect a washout on Wednesday. The system will bring periods of rain, gusty winds and the potential for thunderstorms as a cold front approaches.

Areas of southern New Jersey have the best chance of seeing enough instability for stronger thunderstorms. If storms develop, the strong winds aloft could mix down to the surface, bringing a risk of damaging wind gusts.

Outside of thunderstorms, winds will be gusty throughout the day, with sustained winds of 25-35 mph and gusts potentially exceeding 40-50 mph. The cold front will move through Wednesday evening, bringing an end to precipitation and ushering in drier air, the FOX Forecast Center noted. Winds are likely to continue to be gusty as post-frontal winds move in.

Rain amounts will not be considerably high, with 1–2 inches expected. Some of the rain could fall in a short period, which has prompted a low-end flash flood threat across the region.

What they're saying:

"It looks like by the afternoon commute, that's when we'll start to see this line pushing in here, it's going to blossom too as it makes its approach to the Tri-State area," Puente said. "Along it, we're going to have the potential for strong to severe weather across our region. Unfortunately, the timing is at the time of the evening commute. So be prepared for that."
