NWS STORM PREDICTION CENTER NORMAN OK
0349 PM CDT TUE JUN 24 2025
AREAS AFFECTED...PORTIONS OF EXTREME NORTHWEST PENNSYLVANIA INTO
EXTREME WESTERN NEW YORK
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 242049Z - 242315Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...A COUPLE OF DAMAGING GUSTS CANNOT BE RULED OUT OVER THE
NEXT SEVERAL HOURS. A SEVERE THUNDERSTORM WATCH IS NOT EXPECTED.
DISCUSSION...A FEW THUNDERSTORMS HAVE INITIATED AND INTENSIFIED OFF
OF SURFACE BOUNDARIES AND CONFLUENCE ZONES OVER THE PAST COUPLE OF
HOURS. DEEP-LAYER FLOW AND SHEAR, AS WELL AS BUOYANCY, ARE MODEST AT
BEST ACROSS THE REGION (E.G. 1000 J/KG MLCAPE AMID LESS THAN 20 KTS
OF EFFECTIVE BULK SHEAR). AS SUCH, A COUPLE OF BRIEF DOWNBURSTS MAY
CAUSE SPARSE TREE DAMAGE IN THE NEAR-TERM. RELATIVELY MORE ROBUST
STORMS ARE CURRENTLY TRACKING ACROSS EXTREME SOUTHEAST ONTARIO.
THESE STORMS MAY CROSS LAKE ERIE A FEW HOURS FOR NOW, PERHAPS WITH A
SLIGHTLY GREATER DAMAGING GUST THREAT. NONETHELESS, THE SEVERE
THREAT SHOULD REMAIN LOCALIZED, PRECLUDING THE NEED FOR A SEVERE
THUNDERSTORM WATCH.
