Areas affected...northeast MN and extreme northwest WI

Concerning...Heavy snow=20

Valid 141006Z - 141500Z

SUMMARY...Moderate to heavy snow will spread north into northeast MN
and far northwest WI through the early morning hours. Snowfall rates
near 1 inch per hour are expected.

DISCUSSION...A band of moderate to heavy snow will lift northward
from central MN into northeast MN and extreme northwest WI over the
next few hours. This area of snow is developing along an area of
increasing 700 mb frontogenesis and midlevel warm advection as a
midlevel low over eastern NE pivots northeast. Strong ascent through
a deep saturated profile and a dendritic growth layer around 2500
feet deep will result in efficient snowfall rates around 1 inch per
hour. Some localized, brief rates near 2 inches an hour will be
possible within mesoscale bands through the early morning hours.
