Areas affected...far southeastern Minnesota into west-central
Wisconsin

Concerning...Heavy snow=20

Valid 191548Z - 191845Z

SUMMARY...Areas of heavy snow with rates around 1" per hour to
continue through the late morning.

DISCUSSION...Bands of moderate to heavy snow are ongoing across
portions of southeastern MN into west-central WI. The heaviest snow
appears to be focused near the MN/WI/IA border where upper-level
divergence from a mid-level shortwave is leading to greater forcing
amid deep moist convergence. HREF guidance indicates that rates will
come down into the afternoon as upper-level support shifts
southward, before the backside of the low shifts across the region
later in the afternoon/evening when rates may increase again.
