   Areas affected...East central Minnesota and northwest Wisconsin

   Concerning...Severe Thunderstorm Watch 542...

   Valid 270140Z - 270315Z

   The severe weather threat for Severe Thunderstorm Watch 542
   continues.

   SUMMARY...The severe threat continues in the southern half of severe
   thunderstorm watch 542.

   DISCUSSION...A cluster of supercells has been persistent in the
   northern suburbs of Minneapolis for the past hour with several
   reports of 1 to 2 inch hail. There have been occasional attempts at
   convection in the northern half of the watch between this cluster of
   supercells and the line up near Lake Superior, but no convection has
   been able to persist. Given the MLCIN from the 00Z MPX sounding,
   additional convection is not anticipated outside of the ongoing
   supercells north of MPX. Even this convection will likely weaken
   below severe limits in the next 1 to 2 hours as CIN increases
   further. Some evidence of these storms struggling with the capping
   inversion has been apparent in the past 1 to 2 hours as the lead
   supercell dissipated quickly between 0030Z-0100Z.
