A Potent and somewhat regionalized winter storm event will impact areas from NW Iowa to the Arrowhead of Minnesota mainly tonight through Thursday.
WRF high-res snowfall models and NAM indicate very aggressive moisture advection into cold air - resulting in snowfall accumulations mainly from 6 to 10" and potentially higher in areas from Storm Lake area and NE into SC Minnesota.
Winds will also be a factor with this winter storm. Snow type will be wet and heavy and will mix with and change to rain farther southeast.
Winter Storm Watches are in effect from NW Iowa Northeast through the arrowhead of Minnesota. There is the potential for localized 12" plus snowfall accumulations in the heaviest snowbands.
GFS is not as hard on accumulation totals. There will also be a sharp gradient on the NW side of the storm as it encounters drier air.
