Today's weather NYC: Outlooks

Much of New Jersey is under a slight risk for severe weather, while other parts of the Tri-State area, including NYC, are under a marginal risk.

Parts of central NJ have been placed in a Level 2 out of 5 risk on the NOAA's Storm Prediction Center's (SPC) 5-point severe thunderstorm risk scale.

"In either one of those, you could see some stronger storms with heavy rain, gusty winds, small hail and, every once in a while, an isolated tornado," Woods said. "Just a little more likely for you in the yellow-shaded area."

Meanwhile, NYC is under a moderate risk for excessive rainfall, which means numerous flash floods are likely, according to the NWS.
