NWS STORM PREDICTION CENTER NORMAN OK
1151 AM CDT THU JUL 10 2025
AREAS AFFECTED...NORTHEAST OHIO INTO NORTHERN PENNSYLVANIA AND
WESTERN NEW YORK
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 101651Z - 101845Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...ISOLATED THUNDERSTORMS DEVELOPING THROUGH THE AFTERNOON
WILL BE CAPABLE OF DAMAGING WINDS. WATCH ISSUANCE IS NOT EXPECTED.
DISCUSSION...LATEST GOES IMAGERY AND LIGHTING DATA SHOW THE EARLY
STAGES OF THUNDERSTORM DEVELOPMENT ACROSS NORTHEAST OH INTO WESTERN
NY WITHIN A DIFFUSE SURFACE TROUGH AND ALONG DEVELOPING LAKE BREEZE
BOUNDARIES. THUNDERSTORM COVERAGE SHOULD SLOWLY INCREASE THROUGH THE
AFTERNOON AS TEMPERATURES WARM AND BAROCLINIC CIRCULATIONS
STRENGTHEN ALONG THE LAKE BREEZE BOUNDARIES. DESPITE WARM/MOIST
LOW-LEVEL CONDITIONS, MODEST MID-LEVEL LAPSE RATES SHOULD LIMIT
OVERALL BUOYANCY VALUES TO AROUND 1000-1500 J/KG. ADDITIONALLY,
DEEP-LAYER WIND SHEAR OVER THE REGION REMAINS FAIRLY MEAGER WITH
REGIONAL VWPS AND MORNING RAOBS SAMPLING MID/UPPER-LEVEL WINDS OF
AROUND 20-30 KNOTS. GIVEN WEAK LOW-LEVEL FLOW, THIS WILL BE ADEQUATE
FOR SOME DEGREE OF STORM ORGANIZATION AND PERSISTENCE, BUT SHOULD
MODULATE OVERALL CONVECTIVE INTENSITIES. WATCH ISSUANCE IS NOT
EXPECTED, BUT A FEW INSTANCES OF DAMAGING WINDS APPEAR POSSIBLE AS
STORMS DEVELOP THROUGH THE AFTERNOON.
