   Areas affected...NE Panhandle

   Concerning...Severe potential...Watch possible 

   Valid 010811Z - 011015Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Potential for isolated large hail should persist through
   sunrise with a few elevated supercells across the western Nebraska
   Panhandle vicinity.

   DISCUSSION...A trio of elevated supercells have formed as a result
   of a well-advertised overnight increase in low-level moisture
   northward over the central High Plains. The northwestern most of
   this trio, near Alliance, appears to be the deepest updraft. With
   MUCAPE having increased to about 1000 J/kg coupled with moderate
   northwesterly deep-layer shear, the threat for large hail will
   probably persist for a few hours through at least sunrise. Low-level
   flow appears to be relatively modest, yielding some uncertainty on
   how long the severe hail threat will last. 00Z HREF signal suggests
   relatively shorter-lived supercells should be expected, although the
   00Z NSSL-MPAS runs indicated potential for a longer-lived, more
   intense storm occurring.
