Areas affected...northeast North Dakota into far northwest Minnesota

Concerning...Heavy snow=20

Valid 050134Z - 050330Z

SUMMARY...Occasional instances of 1 inch/hour snow fall rates are
expected over the next few hours in association with a primary snow
band. Periods of gusty winds and reduced visibility may also promote
hazardous road conditions in the core of the snow band.

DISCUSSION...Wrap-around snowfall should continue to the north of a
700 mb low centered over eastern SD. 00Z mesoanalysis shows strong
700 mb warm-air advection grazing the northern Plains, providing
enough lift, moisture, and convergence to support periods of heavy
snow across eastern ND into far northern MN. This 700 mb warm-air
advection should gradually drift north-northeastward through the
evening, resulting in a gradual weakening of the snow band later
tonight. In the meantime, periods of 1 inch/hr snow fall rates
should continue over the next few hours, accompanied by strong wind
gusts. The wind gusts and reduced visibility with the heavier snow
rates may promote hazardous road conditions over the next few hours.
