   MESOSCALE DISCUSSION 0265
   NWS STORM PREDICTION CENTER NORMAN OK
   1254 PM CDT THU MAR 24 2016

   AREAS AFFECTED...FAR ERN IL...SRN AND CNTRL IND...SW OH...WRN AND
   CNTRL KY

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 241754Z - 242030Z

   PROBABILITY OF WATCH ISSUANCE...40 PERCENT

   SUMMARY...AN ISOLATED WIND DAMAGE AND HAIL THREAT MAY DEVELOP OVER
   THE NEXT FEW HOURS FROM NEAR THE IL-IND STATE-LINE EWD ACROSS PARTS
   OF KY AND IND INTO SW OH. WW ISSUANCE MAY BECOME NECESSARY ACROSS
   THE REGION THIS AFTERNOON.

   DISCUSSION...LATEST SFC ANALYSIS SHOWS A 997 MB LOW OVER NE IL WITH
   A COLD FRONT EXTENDING FROM THE SFC LOW SWD ACROSS ECNTRL IL INTO
   FAR WRN KY. A CORRIDOR OF LOW-LEVEL MOISTURE IS PRESENT AHEAD OF THE
   FRONT ACROSS WRN TN...WRN KY AND SW IND WHERE SFC DEWPOINTS ARE IN
   THE UPPER 50S TO LOWER 60S F. ALTHOUGH SFC HEATING HAS BEEN SLOW TO
   OCCUR TODAY IN THE OH VALLEY...WEAK INSTABILITY HAS DEVELOPED ALONG
   THE MOIST CORRIDOR WHERE WIDELY SCATTERED SHOWERS AND A FEW
   THUNDERSTORMS HAVE DEVELOP EARLY THIS AFTERNOON. THE LATEST HRRR
   SUGGESTS THAT CONVECTION WILL GRADUALLY INTENSIFY ALONG SEVERAL
   BANDS AS INSTABILITY CONTINUES TO INCREASE THIS AFTERNOON. THE
   LATEST WSR-88D VWPS FROM INDIANAPOLIS AND PADUCAH SHOW 0-6 KM SHEAR
   IN THE 55 TO 60 KT RANGE WITH 40 TO 50 KT OF FLOW AT 1 KM AND
   UNIDIRECTIONAL WIND PROFILES. THIS MAY SUPPORT MULTICELL LINE
   SEGMENTS CAPABLE OF PRODUCING DAMAGING WIND GUSTS WHERE SFC TEMPS
   ARE ABLE TO WARM ALONG ZONES OF LOW-LEVEL CONVERGENCE. STEEP LAPSE
   RATES AND COLD AIR ALOFT ASSOCIATED WITH THE APPROACHING UPPER-LEVEL
   TROUGH MAY ALSO SUPPORT HAIL WITH THE STRONGER UPDRAFTS.
