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

   Concerning...Heavy snow 

   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.
