   ...THERE IS A SLGT RISK OF SVR TSTMS FROM PARTS OF THE OH VALLEY
   INTO THE GREAT LAKES AREA...
   
   ...OH VALLEY THROUGH GREAT LAKES...
   
   VORT MAX OVER SW IL THIS MORNING WILL CONTINUE NNE INTO THE GREAT
   LAKES AREA TODAY WHILE BROADER UPPER TROUGH CURRENTLY OVER THE CNTRL
   AND WRN U.S. MIGRATES SLOWLY EWD. IN THE PROCESS...NRN PORTION OF
   COLD FRONT CURRENTLY FROM THE UPPER GREAT LAKES SWWD THROUGH SE MO
   WILL CONTINUE SLOWLY EWD AND EXTEND FROM ERN MI SWWD THROUGH WRN OR
   CNTRL KY BY LATE THIS AFTERNOON.
   
   PRIMARY CONCERN TODAY IS HOW MUCH DESTABILIZATION CAN OCCUR GIVEN
   WIDESPREAD CLOUDS ASSOCIATED WITH ONGOING CONVECTION WITHIN THE WARM
   CONVEYOR BELT ACROSS THE TN AND OH VALLEYS AND POOR LAPSE RATES PER
   MORNING RAOB DATA. MORNING VISIBLE IMAGERY SHOWS BREAKS IN THE
   CLOUDS FROM ERN KY...ERN IND...ERN MI THROUGH OH SUGGESTING THESE
   AREAS WILL RECEIVE SOME HEATING TODAY...BUT GIVEN MID LEVEL LAPSE
   RATES GENERALLY AOB 5.8 C/KM MLCAPE WILL LIKELY REMAIN AOB 1000
   J/KG.
   
   STRONG LOW-MID LEVEL WIND FIELDS WILL ACCOMPANY THE SHORTWAVE TROUGH
   THROUGH THE OH VALLEY AND INTO THE GREAT LAKES AREA TODAY. LOW LEVEL
   JET FROM 40 TO 50 KT IS EXPECTED TO PERSIST IN WARM SECTOR FROM
   PARTS OF IND...OH AND MI. ONGOING PRE-FRONTAL CONVECTION MAY SERVE
   AS EFFECTIVE BOUNDARIES FOR ADDITIONAL STORMS TO DEVELOP. ACTIVITY
   IS EXPECTED TO GRADUALLY INTENSIFY AS THE ATMOSPHERE DESTABILIZES
   DURING THE DAY WITH POTENTIAL FOR LINES AND SUPERCELLS. SUPERCELL
   THREAT APPEARS HIGHER FROM PARTS OF NRN IND/OH INTO ERN MI WHERE
   STRONGER MID/UPPER FLOW AND DEEP LAYER SHEAR IS EXPECTED. DAMAGING
   WIND APPEARS TO BE THE PRIMARY THREAT.
   
   ...LOWER RIO GRANDE THROUGH S TX...
   
   STORMS MAY REDEVELOP IN THE UPSLOPE REGION OF NRN MEXICO THIS
   AFTERNOON AS THE ATMOSPHERE DESTABILIZES. SOME POTENTIAL WILL EXIST
   FOR THIS ACTIVITY TO MIGRATE EWD INTO PARTS OF S AND SW TX WHERE
   DESTABILIZATION MAY OCCUR S OF STALLED BOUNDARY.
   
   
   ...MID ATLANTIC AREA...
   
   STRONG SURFACE HEATING WILL LIKELY SUPPORT MODERATE INSTABILITY OVER
   PARTS OF THE MID ATLANTIC REGION. VERTICAL WIND AND SHEAR PROFILES
   ARE WEAK. HOWEVER...POTENTIAL WILL EXIST FOR ISOLATED PULSE SEVERE
   STORMS THROUGH EARLY EVENING.
