A strong cold front cutting into an unusually warm, muggy airmass for early-September is setting the stage for some potentially strong t-storms in the Northeast today. As of mid-morning, the main line of storms was in Western New York and Western Pennsylvania, with some scattered strong storms developing in the super-charged atmosphere over New Jersey and Southeastern NY – including New York City.
The National Weather Service office in Taunton, MA has issued a special weather statement regarding the potential for strong to severe t-storms later today.
...SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON INTO TONIGHT ACROSS PORTIONS OF SOUTHERN NEW ENGLAND... THUNDERSTORMS MAY DEVELOP ACROSS SOUTHERN NEW ENGLAND BETWEEN NOON AND 2 PM...THEN BECOME MORE NUMEROUS DURING THE MID AND LATE AFTERNOON. SOME STORMS WILL LIKELY CONTAIN STRONG OR DAMAGING WINDS. THEY WILL ALSO CONTAIN TORRENTIAL DOWNPOURS WHICH MAY CAUSE SMALL STREAM AND POOR DRAINAGE FLOODING. THERE IS A MUCH LOWER CHANCE OF TORNADOES...BUT IT IS A CHANCE WORTH MENTIONING. ALTHOUGH SEVERE THUNDERSTORMS IN NEW ENGLAND TYPICALLY DIMINISH WITH SUNSET...THESE THUNDERSTORMS WILL LIKELY CONTINUE INTO EARLY NIGHT WITH CONTINUED CHANCE OF STRONG OR DAMAGING WINDS AND TORRENTIAL DOWNPOURS. THE GREATEST RISK FOR STRONG TO SEVERE THUNDERSTORMS THIS AFTERNOON WILL BE ACROSS CONNECTICUT...WESTERN MASSACHUSETTS...AND SOUTHWEST NEW HAMPSHIRE. THIS AREA WILL SPREAD EAST THIS EVENING AND TONIGHT.
