   Areas affected...Upper Fox River Valley vicinity into southern Upper
   Peninsula of Michigan

   Concerning...Severe Thunderstorm Watch 203...

   Valid 260056Z - 260230Z

   The severe weather threat for Severe Thunderstorm Watch 203
   continues.

   SUMMARY...Strong to locally severe gusts possible in the near-term,
   particularly for southern portions of the Upper Peninsula.

   DISCUSSION...The 00Z GRB sounding showed mid-level lapse rates of
   around 7 C/km with 42 kts of effective shear. The portion of the
   line moving into the Upper Peninsula is moving at around 40-45 kts.
   This would suggest that even marginal enhancement of the winds by
   the convection would result in strong to perhaps locally severe
   gusts. Within the past 20-30 minutes, KIMT ASOS measured 44 kts.
   These gusts will remain possible until the line encounters greater
   MLCIN with the marine layer.
