PENNSYLVANIA – There is a high possibility of strong tornadoes sweeping through Pennsylvania this afternoon. According to the National Weather Service Storm Prediction Center, tornadoes can sweep over New York City, Jersey City, Yonkers, and Providence.
There is a risk for high-speed winds and small tornadoes in Westmoreland County, State College, Philadelphia, Washington D.C. and Baltimore.
SUPERCELLS ARE POSSIBLE TO FORM TORNADOES
Butler County, PA is in a marginal risk for today. This includes severe weather such as small hail, high winds, and extended downpours which can cause flooding.
Thunderstorms are expected to develop and grow upscale from midday
through afternoon, sweeping eastward across the region with the main
risk being severe wind. The potential for a well-organized swath of
damaging wind — including a few gusts around hurricane force —
appears greatest over the enhanced-risk area. Large hail also is
possible, especially in the first few hours of the convective cycle
when storm modes can be more favorably discrete or semi-discrete. A
few tornadoes also may occur, whether from supercells or
