Areas affected...Northeast ND...northern/central MN

Concerning...Heavy snow=20

Valid 111608Z - 112015Z

SUMMARY...Heavy snowfall with rates up to 1" per hour are possible
from northeast ND into northern/central MN over the next few hours.

DISCUSSION...A vertically stacked mid-latitude cyclone is currently
centered near the MT/ND border vicinity, with its warm conveyor
arcing from the central Plains into the Upper Midwest and back into
the Canadian Prairie Provinces. Expectation is for this cyclone to
continue eastward today, while continuing to occlude. As it does,
strong ascent will persist along and north of the
northeastward-progressing dry slot, contributing to a band of a
heavy snow from northeast ND southeastward across MN. This band is
expected to move northeastward quickly, with snowfall rates around
1" per hour possible for an hour or two within the heaviest portions
of the band.
