   VALID 262045Z - 262215Z
   
   WIDELY SCATTERED LOCALLY INTENSE STORMS ARE EXPECTED TO CONTINUE IN
   A BROAD SWATH FROM THE UPPER OH VALLEY ACROSS THE CUMBERLAND
   PLATEAU/APPALACHIANS THROUGH EARLY EVENING. ISOLATED/RANDOM NATURE
   OF THE THREAT OF DAMAGING WINDS/HAIL WILL LIKELY PRECLUDE A WATCH.
   
   POCKETS OF STRONG TO SEVERE STORMS ARE ONGOING WITHIN BROAD CYCLONIC
   FLOW REGIME IN THE SERN QUADRANT OF LARGE SCALE CLOSED LOW ACROSS
   THE UPPER MIDWEST/GREAT LAKES. AN AXIS OF MODEST TO LOCALLY STRONG
   INSTABILITY ACROSS THE AREA WILL CONTINUE TO PROVIDE THE FUEL FOR A
   FEW SEVERE STORMS CONTAINING HAIL AND PERHAPS ISOLATED DOWNBURSTS.
   LACK OF WELL-DEFINED LOW LEVEL FOCUS...AND MARGINAL DEEP-LAYER SHEAR
   ACROSS MUCH OF THE REGION...SUGGEST THAT POTENTIAL FOR MORE
   WIDESPREAD SEVERE WEATHER WILL REMAIN LOW. SOMEWHAT STRONGER MID
   LEVEL FLOW OF ABOUT 30KT IS COINCIDENT WITH THE LOW LEVEL
   INSTABILITY AXIS FROM NRN KY ACROSS PARTS OF SERN OH/WRN PA. MORE
   PERSISTENT UPDRAFTS IN THIS CORRIDOR MAY HAVE SLIGHTLY GREATER
   POTENTIAL OF PRODUCING SEVERE WEATHER. HOWEVER...EVEN HERE...STORM
   DURATION/COVERAGE CURRENTLY APPEARS TOO LIMITED FOR A WATCH.
