   Concerning...Severe Thunderstorm Watch 267...

   Valid 020414Z - 020545Z

   The severe weather threat for Severe Thunderstorm Watch 267
   continues.

   SUMMARY...Thunderstorms continue to congeal into a large complex
   across central Nebraska. The overall environment continues to become
   less favorable for large hail or damaging winds. Severe Thunderstorm
   Watch #267 may need to be canceled early.

   DISCUSSION...Thunderstorms have congealed into a large, non-severe
   mesoscale convective system this evening across central Nebraska.
   The thermodynamic environment is weaker than before, with MUCAPE
   values generally at or below 1000 J/kg across the complex, and
   should continue to decrease ahead of the northeastward moving MCS.
   Additionally, deep-layer shear has weakened from earlier to
   generally at or below 30 knots along and ahead of the MCS. Thus,
   absent any notable uptick in thunderstorm intensity, Severe
   Thunderstorm Watch #267 may need to be canceled early. Trends will
   be monitored.
