Areas affected...Northern Wisconsin into the Upper Peninsula of
Michigan

Concerning...Winter mixed precipitation 

Valid 301907Z - 310000Z

SUMMARY...Another round of moderate to heavy snow and sleet/freezing
rain is expected to spread across northern Wisconsin into the Upper
Peninsula of Michigan.

DISCUSSION...Recent surface observations across northern WI report a
mix of sleet/freezing rain to the west/northwest of the Green Bay,
WI area and light to moderate snow across northern/northwest WI.
This precipitation is expected to increase in coverage and intensity
as it spread northeastward through early evening amid strengthening
warm advection between 925-850 mb and within the 700 mb deformation
zone. The steady warm advection will also maintain a warm nose
between 1-2 km AGL that will continue to promote sleet and freezing
rain through the afternoon. Latest guidance continues to suggest
that freezing rain rates between 0.05 to 0.1 inch/hour are probable
across far northeast WI into the southern areas of the U.P. A
gradual eastward shift of the warm nose is anticipated through late
afternoon, which should result in sub-freezing temperatures
throughout the column. This thermodynamic trend, coupled with
organized precipitation banding, should promote areas of moderate to
heavy snowfall rates between 1-2 inch/hour across northern WI into
western parts of the U.P.
