   0543 PM CDT Thu May 12 2022

   Areas affected...South-central Nebraska and far northern Kansas

   Concerning...Severe Thunderstorm Watch 208...210...

   Valid 122243Z - 122345Z

   The severe weather threat for Severe Thunderstorm Watch 208, 210
   continues.

   SUMMARY...A brief large hail/damaging wind threat is possible across
   north-central Kansas and south-central Nebraska this evening.

   DISCUSSION...Storms have developed along central Nebraska this
   evening as the rapidly moving cold front has overtaken the dryline.
   Storms have been pretty weak thus far, likely due to them forming in
   an airmass which was overturned by earlier convection. Farther
   south, a more unstable airmass is in place with temperatures still
   in the upper 80s and 2000+ J/kg MLCAPE. Therefore, expect more
   vigorous storm development over the next hour or so as the cold
   front continues to overtake the dryline. 

   Additionally, a small cluster of storms has already developed along
   the dryline in southeast Grove County, Kansas. The environment
   remains favorable for this cluster to persist for another hour or
   two before the boundary layer begins to cool and the storm is
   expected to weaken. WFO DDC has expanded watch 210 to cover the
   severe threat from this cluster.
