   Concerning...Severe Thunderstorm Watch 299...

   Valid 101118Z - 101245Z

   The severe weather threat for Severe Thunderstorm Watch 299
   continues.

   SUMMARY...An isolated large hail and damaging wind threat will
   accompany a small cluster of storms moving into central Wisconsin
   this morning.

   DISCUSSION...Warm advection over the outflow from earlier morning
   convection has promoted a few stronger/deeper thunderstorms within
   the northern Coulee region. This activity is on the fringe of the
   steeper mid-level lapse rates and effective shear (perhaps around
   25-30 kt). It is not clear how far east this complex of storms will
   progress as buoyancy and shear decrease with eastward extent and the
   low-level jet will weaken. The current thinking is that isolated
   large hail and perhaps strong/damaging winds are possible over the
   next 1-2 hours. An additional watch is not currently expected this
   morning.
