   Areas affected...Southern Minnesota

   Concerning...Blizzard 

   Valid 182023Z - 190030Z

   SUMMARY...Patchy blizzard conditions are spreading southeast into
   south-central Minnesota and may persist for several hours.

   DISCUSSION...Recent surface observations from across south-central
   MN have begun to report visibility reductions of 1/2 to 1/4 mile
   under a swath of light snowfall. Traffic and snow plow cameras show
   areas of substantial visibility reductions, estimated to be down to
   1/10 mile at times. Widespread 40-60 mph wind gusts continue across
   the region and will support similar visibility reductions under any
   areas with even light snowfall rates. Recent high-res guidance
   suggests that winds may peak over the next hour before gradually
   diminishing through the evening hours; however, gusts between 30-45
   mph will likely continue for the next several hours with a
   continuation of light snowfall within the mid-level TROWAL region of
   the maturing cyclone. As such, areas of transient blizzard
   conditions will likely continue through early/mid-evening.
