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.
