   MESOSCALE DISCUSSION 0292
   NWS STORM PREDICTION CENTER NORMAN OK
   0615 PM CDT WED MAR 30 2016

   AREAS AFFECTED...ARK-LA-MISS

   CONCERNING...TORNADO WATCH 60...

   VALID 302315Z - 310045Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 60 CONTINUES.

   SUMMARY...PORTIONS OF WW 60 HAVE BEEN LOCALLY EXTENDED IN CNTRL/SRN
   AR AND A NEW TORNADO WILL LIKELY BE ISSUED ACROSS THE ARK-LA-MISS
   REGION.

   DISCUSSION...TRANSIENT ROTATIONAL SIGNATURES HAVE BEEN NOTED WITHIN
   A MESSY CONVECTIVE CLUSTER ACROSS CNTRL/S-CNTRL AR. THIS ACTIVITY IS
   EVOLVING WITHIN VERY STRONG LOW-LEVEL SHEAR CHARACTERIZED BY 50-60
   KT 1-KM AGL FLOW PER 21Z LZK RAOB AND LZK VWP DATA. DESPITE THE
   PRESENCE OF MIDDLE 60S SURFACE DEW POINTS...21Z LZK RAOB SUGGESTS
   CONVECTION NEAR/N OF THE LITTLE ROCK METRO AREA WILL LIKELY STRUGGLE
   TO HAVE APPRECIABLE STRETCHING POTENTIAL. HOWEVER...FARTHER SE WHERE
   SURFACE TEMPERATURES HAVE WARMED INTO THE LOWER TO MIDDLE 70S...THE
   RISK FOR AN EMBEDDED SUPERCELL PRODUCING A TORNADO SHOULD DEVELOP E
   INTO THE ARK-LA-MISS PORTION OF THE MS VALLEY.
