***A SPECIAL WEATHER STATEMENT*** A SQUALL LINE OF STRONG THUNDERSTORMS ARE CURRENTLY PUSHING EAST SOUTHEAST FROM LAKE ONTARIO/ NORTHWESTERN, NY...FROM ROCHESTER/ BATAVIA- HAMLIN AREAS TO AROUND MT. MORRIS/ DANSVILLE & THE GENESSEE VALLEY. THIS AREA OF STRONG T-STORMS CONTAIN SMALL HAIL, FREQUENT LIGHTNING & STRONG GUSTY WINDS WHICH HAS THE POTENTIAL TO BECOME SEVERE AS THE SQUALL LINE SWEEPS ACROSS THE WESTERN/ CENTRAL FINGER LAKES REGION DURING THE NEXT COUPLE HOURS WITH POSSIBLE DAMAGING WINDS, LARGE HAIL & FREQUENT/ DEADLY CLOUD TO GROUND LIGHTNING. THERE MAYBE A COUPLE OF BRIEF T-STORMS TO LOWER INTO THE CENTRAL SOUTHERN TIER, AS WELL WITH STRENGTHENING OF BOTH A LOW- LEVEL JET WIND FROM THE WEST SOUTHWEST & A WARM/ MOIST ADVECTED IMPULSE FROM THE WARM FRONT LIFTING NORTHEAST THROUGH CENTRAL, NY TO THE NY/ PA BORDER. THERE IS ALSO THE SLIGHT RISK OF AN ISOLATED TORNADO OR TWO ACROSS UPSTATE NY, AS VERTICAL WIND SHEAR INCREASES, ALONG WITH UNIDIRECTIONAL CLOUD FORMATION ALOFT FROM A SIGNIFICANT INFLUX OF WARM/ HUMID FORCING AIR RISING OVER THE TOP OF COOLER/ DRYER DOME OF AIR AT THE SURFACE. **FROM** STEVE MATTISON...VOLUNTEER SKYWARN SPOTTER FOR THE NWS.
