   Areas affected...the southern Nebraska Panhandle

   Concerning...Severe potential...Watch unlikely 

   Valid 032241Z - 032345Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A cluster of storms have lifted north of watch 321. While
   severe weather is possible in the southern row of NE panhandle
   counties, no additional watch is planned due to the limited area of
   the threat.

   DISCUSSION...The storm along the CO/WY/NE border currently has a
   MESH core suggestive of ping pong ball sized hail and has recently
   reported hail slightly larger than quarters. While the shear in this
   area is relatively weak, (25-30 knots per CYS VWP), the storm is
   moving toward an increasingly unstable airmass in a steep lapse rate
   environment. Therefore, this storm will likely continue to pose a
   threat for both large hail and damaging winds. In addition, the
   storm has recently started to indicate low-level mesocyclone
   strengthening over the past 15 minutes. The easterly low-level flow
   has yielded over 200 m2/s2 of 0-1 SRH which would continue to
   support some low-level rotation, however, high LCL's may act as a
   limiting factor for tornado development.

   While this storm and others within this cluster are expected to
   maintain strong to severe intensity, the limited risk area outside
   of the watch (3 counties in the southern NE panhandle), will likely
   preclude the issuance of a new watch to cover the threat.
