   Areas affected...eastern Minnesota and western Wisconsin

   Concerning...Severe Thunderstorm Watch 301...

   Valid 102247Z - 110015Z

   The severe weather threat for Severe Thunderstorm Watch 301
   continues.

   SUMMARY...Isolated large hail and damaging wind gusts are expected
   to persist for a few more hours.

   DISCUSSION...A cluster of supercells across eastern Minnesota and
   western Wisconsin will persist for a few more hours within an
   environment featuring 2500-3000 J/kg MUCAPE (per SPC mesoanalysis)
   and 50 knots of 50+ knots of 0-6km shear (per MPX VWP). Isolated
   large hail and damaging wind gusts will be the primary threats. As
   these storms continue east over the next 1 to 2 hours they will
   eventually encounter a much more stable environment across Wisconsin
   and should dissipate later this evening.
