   MESOSCALE DISCUSSION 1209
   NWS STORM PREDICTION CENTER NORMAN OK
   0332 AM CDT MON JUN 30 2014

   AREAS AFFECTED...NE NEB...WRN AND CNTRL IA

   CONCERNING...SEVERE THUNDERSTORM WATCH 371...

   VALID 300832Z - 300930Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 371
   CONTINUES.

   SUMMARY...AN ISOLATED THREAT FOR HAIL AND WIND DAMAGE WILL LIKELY
   CONTINUE ACROSS WW 371. OTHER SEVERE STORMS WILL CONTINUE TO HAVE A
   WIND DAMAGE AND HAIL THREAT IN NWRN AND CNTRL IA. WW ISSUANCE WILL
   PROBABLY BE NEEDED TO THE EAST OF WW 371 WITHIN AN HOUR OR TWO.

   DISCUSSION...THE LATEST SFC ANALYSIS SHOWS A 1001-MB LOW OVER SE CO
   WITH A TROUGH EXTENDING NEWD ACROSS NW KS...SERN NEB INTO WRN IA. A
   CORRIDOR OF LOW-LEVEL MOISTURE EXISTS ACROSS NRN KS...SERN NEB AND
   SRN IA WITH A SHARP MOISTURE GRADIENT LOCATED FROM NRN NEB EWD INTO
   NWRN IA. SCATTERED THUNDERSTORMS ARE ONGOING NEAR THIS GRADIENT WITH
   MUCAPE ESTIMATED IN THE 1500 TO 2500 J/KG RANGE ACROSS THE MCD AREA.
   INCREASING WARM ADVECTION EARLY THIS MORNING IN THE CNTRL PLAINS AND
   MID MO VALLEY SHOULD HELP SUSTAIN THE STORMS ACROSS NERN NEB AND
   NWRN IA. THIS ACTIVITY MAY EXPAND IN COVERAGE WITH MCS DEVELOPMENT
   POSSIBLE TOWARD DAYBREAK. IN ADDITION...THE WSR-88D VWPS AT DES
   MOINES IA AND OMAHA NEB SHOW 0-6 KM SHEAR IN THE 55 TO 60 KT RANGE.
   THIS COMBINED WITH THE MODERATE INSTABILITY SHOULD SUPPORT AN
   ISOLATED THREAT FOR WIND DAMAGE AND HAIL EARLY THIS MORNING. THE
   SEVERE THREAT COULD INCREASE AS THE CONVECTION GROWS UPSCALE OVER
   THE NEXT FEW HOURS.
