   MESOSCALE DISCUSSION 0571
   NWS STORM PREDICTION CENTER NORMAN OK
   0616 PM CDT SAT MAY 09 2015

   AREAS AFFECTED...EXTREME SOUTHWEST NEB...EASTERN CO AND WESTERN KS

   CONCERNING...TORNADO WATCH 149...

   VALID 092316Z - 100115Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 149 CONTINUES.

   SUMMARY...A TORNADO THREAT WILL CONTINUE THE NEXT FEW HOURS ACROSS
   PARTS OF EASTERN CO AND WESTERN KS. LARGE HAIL AND GUSTY WINDS ALSO
   WILL BE POSSIBLE. THE GREATEST THREAT WILL BE OVER EAST-CENTRAL CO
   INTO WESTERN KS AS ISOLATED STORMS TRACK GENERALLY NORTH/NORTHEAST.

   DISCUSSION...THE SURFACE WARM FRONT HAS BEEN SLOWLY LIFTING
   NORTHWARD THIS AFTERNOON. THE BEST TORNADO ENVIRONMENT WILL EXIST
   FROM E-CENTRAL CO INTO WRN KS IN A NARROW WEDGE OF WARM SECTOR AIR
   EAST OF THE DRYLINE AND SOUTH OF THE WARM FRONT. MODEST SURFACE
   BASED CAPE AND 0-6 KM SHEAR NEAR 50 KT WILL BE ADEQUATE FOR
   SUPERCELL STRUCTURES. THE 23Z GLD VWP INDICATED A SMALL BUT
   FAVORABLE LOW LEVEL HODOGRAPH WITH AROUND 150 M2/S2 0-3KM SRH. GIVEN
   THE VICINITY TO THE SURFACE LOW AND THE FAVORABLE
   SHEAR/THERMODYNAMIC ENVIRONMENT WITH PLENTY OF SFC BOUNDARIES IN THE
   REGION...THE TORNADO THREAT LIKELY WILL CONTINUE FOR AT LEAST A
   COUPLE MORE HOURS. IN ADDITION TO TORNADO...HAIL AND GUSTY WIND ALSO
   WILL BE POSSIBLE.
