   Concerning...Severe Thunderstorm Watch 467...

   Valid 272347Z - 280045Z

   The severe weather threat for Severe Thunderstorm Watch 467
   continues.

   SUMMARY...Severe gusts remain possible with several clusters of
   strong to severe storms ongoing across NE. Some hail is also
   possible.

   DISCUSSION...As of 2340 UTC, regional radar imagery showed several
   clusters of strong to severe storms ongoing across WW467. Mostly
   outflow dominate, these clusters should persist in an unstable
   environment (3000+ j/kg MLCAPE) supportive of strong updrafts. The
   degree of buoyancy and steep low-level lapse rates suggest damaging
   gusts and some hail will remain possible with these clusters as they
   slowly move eastward this evening. 

   The severe threat should continue this evening, though the eastern
   extent of the more robust threat remains somewhat unclear. So far
   storm organization has been limited, and MLCIHN has started to
   slowly increase from warm mid-level temperatures and weaker forcing
   ascent displaced to the north. As the storms and outflow continue
   eastward the severe threat may extended beyond the eastern edge of
   Watch 467. Some model guidance shows an uptick in convective
   coverage later as the low-level jet increases, but this remains
   unclear. A local extension of WW467 may be needed should storms show
   an increase in intensity.
