   Areas affected...Portions of central KS...south-central into eastern
   NE...and far west-central IA

   Concerning...Severe Thunderstorm Watch 325...

   Valid 140048Z - 140215Z

   The severe weather threat for Severe Thunderstorm Watch 325

   SUMMARY...Thunderstorms that have erupted along a dryline will
   continue to pose a threat for scattered large hail and damaging
   winds through the remainder of the evening as they move
   east-northeastward across WW 325.

   DISCUSSION...A line of storms quickly developed along a dryline
   across south-central NE from 2330Z to 0045Z, with embedded
   supcercells producing multiple reports of large hail, some greater
   than 2 inches in diameter. This ongoing convection will develop
   eastward into eastern NE and more of north-central KS over the next
   several hours, where a very unstable airmass (MLCAPE around 3250
   J/kg per 00Z Omaha NE sounding) will prove more than adequate to
   maintain current severe-caliber storm intensities. Recent radar
   trends from the KOAX radar suggest a bowing segment may be forming
   across eastern NE, with strong 70+ kt inbound velocities noted
   around 7000 ft AGL. Scattered damaging winds will likely become the
   main threat across most of WW 325 though the remainder of the
   evening as this line of storms moves east-northeastward with time,
   although large hail will continue to be possible with any embedded
