   MESOSCALE DISCUSSION 0243
   NWS STORM PREDICTION CENTER NORMAN OK
   0725 PM CDT TUE APR 01 2014

   AREAS AFFECTED...HASKELL AND THROCKMORTON COUNTIES IN NORTH TEXAS

   CONCERNING...SEVERE THUNDERSTORM WATCH 45...

   VALID 020025Z - 020100Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 45
   CONTINUES.

   SUMMARY...SUPERCELL STORMS WILL CROSS PORTIONS OF HASKELL AND
   THROCKMORTON COUNTIES IN NORTH TEXAS AND POSE SOME POSSIBILITY FOR
   SIGNIFICANT HAIL IN THE NEXT HOUR.

   DISCUSSION...UPDRAFTS ARE CONGEALING INTO A FEW SEMI-DISCRETE
   SUPERCELLS OVER THROCKMORTON AND HASKELL COUNTIES. SPACING BETWEEN
   THE SERN HASKELL COUNTY STORM AND DEVELOPING CONVECTION IMMEDIATELY
   TO THE SW SHOULD REMAIN SUFFICIENTLY LARGE IN THE SHORT TERM FOR
   VIGOROUS UPDRAFTS TO MAINTAIN A SVR POTENTIAL. THE DEVELOPING
   CONVECTION COULD ALSO FURTHER INTENSIFY AS ITS INFLOW IS
   UNDISTURBED. THERMODYNAMIC AND KINEMATIC PARAMETERS WILL REMAIN
   FAVORABLE FOR THE PRODUCTION OF SVR HAIL...SOME POSSIBLY SIGNIFICANT
   OVER SRN/CNTRL THROCKMORTON/HASKELL COUNTIES -- GIVEN MODERATE
   INSTABILITY AND 50 KT OF EFFECTIVE BULK SHEAR SAMPLED BY THE
   DOWNSTREAM 00Z FWD RAOB. NSSL WDSS-II MESH DATA AFFIRM SOME
   POSSIBILITY FOR SIGNIFICANT HAIL.
