1154 AM CDT SUN AUG 02 2026
AREAS AFFECTED...PORTIONS OF WESTERN NY
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 021654Z - 021830Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...AN ISOLATED RISK FOR DAMAGING WIND GUSTS AND PERHAPS A
TORNADO WILL SKIRT THE INTERNATIONAL BORDER NEAR LAKE
ONTARIO/WESTERN NEW YORK THE NEXT COUPLE HOURS.
DISCUSSION...A BOWING THUNDERSTORM CLUSTER HAS DEVELOPED ALONG A
SURFACE BOUNDARY NEAR THE INTERNATIONAL BORDER/WESTERN NY. THE
DOWNSTREAM AIRMASS IS RELATIVELY COOL, BUT MOIST, RESULTING IN WEAK
INSTABILITY. HOWEVER, LOW-LEVEL SRH IS ENHANCED ALONG THE SURFACE
BOUNDARY AND IN PROXIMITY TO THE LARGER-SCALE SURFACE LOW ACROSS THE
REGION. WHILE INSTABILITY IS EXPECTED TO REMAIN WEAK, 30-40 KT
EFFECTIVE SHEAR MAGNITUDES WILL SUPPORT AT LEAST OCCASIONAL STORM
ORGANIZATION. MOST OF THE STRONGER CONVECTION WILL LIKELY REMAIN
OVER LAKE ONTARIO AND OR ACROSS THE INTERNATIONAL BORDER. HOWEVER,
THIS STRONGER BOWING CLUSTER COULD SKIRT THE WESTERN NY/LAKE ONTARIO
SHORELINE OVER THE NEXT HOUR OR TWO, RESULTING IN A LOW RISK FOR
DAMAGING GUSTS OR PERHAPS A BRIEF TORNADO.
