   NWS STORM PREDICTION CENTER NORMAN OK
   0752 PM CDT TUE JUL 26 2016

   VALID 270100Z - 271200Z

   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE CENTRAL/NRN
   HIGH PLAINS...

   ...THERE IS A MRGL RISK OF SVR TSTMS FROM THE CNTRL HIGH PLAINS TO
   THE UPPER GREAT LAKES...

   ...THERE IS A MRGL RISK OF SVR TSTMS ACROSS THE MIDDLE ATLANTIC...

   ...SUMMARY...
   THUNDERSTORMS MAY PRODUCE SEVERE GUSTS AND LARGE HAIL THIS EVENING
   OVER PARTS OF WESTERN AND CENTRAL NEBRASKA AND SOUTH DAKOTA.

   ...NORTHERN/CENTRAL PLAINS...

   WEAK SHORT-WAVE TROUGH HAS TOPPED THE WRN US RIDGE AND IS DIGGING
   SEWD ACROSS THE BLACK HILLS REGION.  STRONG CONVECTION HAS DEVELOPED
   AHEAD OF THIS FEATURE AND MULTIPLE SUPERCELLS ARE NOW MERGING OVER
   NRN PORTIONS OF WW417.  MRMS DATA SUGGESTS VERY LARGE HAIL HAS BEEN
   NOTED WITH SEVERAL OF THESE UPDRAFTS BUT STORM MERGERS SHOULD LEAD
   TO AT LEAST ONE MCS THIS EVENING AS LLJ INCREASES OVER THE CNTRL
   PLAINS.

   FARTHER NORTH...ISOLATED STRONG STORMS WILL LINGER FROM SERN ND INTO
   CNTRL MN FOR SEVERAL HOURS BEFORE GRADUALLY WEAKENING WITH LOSS OF
   DAYTIME HEATING.

   ...MIDDLE ATLANTIC...

   REMNANT MCV FROM OLD CONVECTION HAS PROGRESSED INTO NRN WV.  THIS
   FEATURE APPEARS TO BE PARTLY RESPONSIBLE FOR SCT CONVECTION THAT
   DEVELOPED ACROSS THE CNTRL APPALACHIANS.  DOWNSTREAM...SEVERAL STORM
   MERGERS ARE ONGOING ACROSS CNTRL VA...AIDED IN PART BY CONVECTIVE
   OUTFLOW INTERACTIONS.  THIS ACTIVITY SHOULD BEGIN TO WEAKEN WITH
   LOSS OF DAYTIME HEATING.  UNTIL THEN...MARGINALLY SEVERE HAIL AND
   GUSTY WINDS CAN BE EXPECTED.
