VEERING WINDS WITH HEIGHT AND FAVORABLE FLOW ALOFT INDICATE A THREAT OF SUPERCELLS CAPABLE OF HAIL…LOCALLY DAMAGING WIND AND PERHAPS A TORNADO. The Slight Risk redevelops on Sunday: AFTERNOON STORM DEVELOPMENT WILL BE MOST LIKELY TO OCCUR FIRST ALONG THE PRIMARY COLD FRONT...FROM NRN INDIANA INTO NRN OH...AND EXTENDING NEWD ACROSS WRN NY. STORMS SHOULD THEN FILL IN SWWD AROUND 00Z ACROSS KY. SUPERCELLS WILL BE THE DOMINANT STORM MODE WITH VERY LARGE HAIL AND A TORNADO OR TWO WITH THE MOST DEVIANTLY-MOVING CELLS...ESPECIALLY THOSE NEAR ANY PRE-EXISTING BOUNDARIES.
