   Mesoscale Discussion 1949
   NWS Storm Prediction Center Norman OK
   0136 PM CST Sun Nov 21 2021

   Areas affected...Northeast Wisconsin

   Concerning...Snow Squall 

   Valid 211936Z - 212230Z

   SUMMARY...Scattered snow showers will continue across portions of
   northeast Wisconsin this afternoon. Strong winds accompanying these
   snow showers may result in visibility dropping to less than a
   quarter-mile at times.

   DISCUSSION...Atmospheric response to strong frontogenesis in the
   850-700 millibar layer is supporting bands of snow showers across
   northeast Wisconsin. These snow bands are occurring within a region
   of strong winds, gusting to between 35 and 45 mph at times. The
   combination of intense snow bands and strong gusty winds will result
   in visibility briefly falling to around or below a quarter-mile at
   times. The threat should end later this afternoon as frontogenetic
   forcing continues to progress through the region.
