   Areas affected...East-central Wisconsin into parts of
   central/southern Lower Michigan

   Concerning...Snow Squall 

   Valid 042140Z - 050045Z

   SUMMARY...Reduced visibility, moderate to heavy snow, and strong
   wind gusts are possible with a shallow convective line of snow along
   the quickly advancing cold front.

   DISCUSSION...A line of semi-organized, shallow convective snow has
   continued across eastern Wisconsin. Recent surface observations from
   Fond du Lac/Oshkosh and vicinity show moderate to heavy snowfall and
   visibility reduced to around 1/4 mile in some locations. Wind gusts
   of 40+ kts remain possible as well per surface observation and
   regional VAD wind profiles. Given the strong frontal forcing, the
   expectation is for this line to continue across Lake Michigan and
   eventually impact portions of central/southern Lower Michigan. Some
   southward expansion of the line is possible, but this should be
   limited by much warmer temperatures in northeast Illinois into
   northern Indiana.
