Areas affected...northern Minnesota

Concerning...Blizzard 

Valid 160443Z - 161045Z

SUMMARY...Near-blizzard conditions will develop tonight into
northern Minnesota, with wind gusts of 40-50 mph expected. Snow
rates may reach around 1"/hr.

DISCUSSION...As a deepening surface low tracks northeast toward Lake
Superior tonight, cooling aloft will result in increasingly
favorable profiles for heavy snow from west to east across northern
MN. Forecast soundings show the top of the boundary layer around 870
mb, with maximum boundary layer winds of 40-45 kt. Given expected
precipitation rates, these wind gusts to this magnitude appear
reasonable, resulting in blowing snow and reduced visibilities. The
heaviest snow rates are likely to occur after 06Z and across
northern into northeastern MN.
