   Areas affected...eastern Minnesota...western/central Wisconsin

   Concerning...Heavy snow 

   Valid 100112Z - 100415Z

   SUMMARY...Heavy snow to continue through the evening with occasional
   1"/hr rates.

   DISCUSSION...Heavy to moderate snow continues to be reported across
   portions of eastern MN into central WI as of 01z. The surface low
   continues to shift south and eastward, currently located over
   southern MN. 750-850 mb frontogenesis is maximized across far
   eastern MN into portions of central WI. 00z sounding from MPX shows
   a nearly saturated dendritic growth zone. Moist profiles and
   continued frontal support will continue to bring potential for heavy
   bands with 1"/hr rates over the next few hours. As the surface low
   continues to shift south and east, rates will decrease through the
   late evening/overnight.
