   Concerning...Severe Thunderstorm Watch 445...

   Valid 220125Z - 220300Z

   The severe weather threat for Severe Thunderstorm Watch 445
   continues.

   SUMMARY...An isolated severe hail/wind threat continues this
   evening.

   DISCUSSION...Training cells are ongoing early this evening across
   south-central into eastern NE along and south of a front. The
   downstream 00Z sounding from OAX shows generally poor mid-level
   lapse rates, with a long/skinny MLCAPE profile. Still, enough
   low-level and deep-layer shear remains present to support organized
   convection, including the potential for supercells. Any thunderstorm
   which can remain at least semi-discrete should have some hail
   threat, even with the poor lapse rates aloft and associated warm
   mid-level temperatures. An isolated threat for severe/damaging winds
   may also continue, especially if thunderstorms can congeal into a
   small bowing cluster this evening in tandem with a gradually
   strengthening low-level jet. The overall tornado threat may be
   tempered by continued messy storm modes, although low-level shear
   should gradually increase this evening. Depending on convective
   trends, a local extension in area for Severe Thunderstorm Watch 445
   may be warranted across parts of central/eastern NE.
