...Northern Plains and Upper Midwest...

A powerful cyclone centered over the central Great Plains this
morning is expected to gradually weaken as it lifts farther to the
northeast toward the Great Lakes on Thursday.  As the large scale
forcing becomes more diffuse and lifts out to the north, a band of
light to moderate snow currently centered across North Dakota and
northwest Minnesota is expected to wane through the remainder of
the overnight into the early daylight hours.

Meanwhile, as cold air continues to wrap in behind the system,
expect to see a continued changeover from rain to snow in a
secondary band that has developed closer to the low center. 
Models show low to mid level frontogenesis supporting some light
snow accumulations before precipitation ends across eastern
Nebraska and South Dakota later today.

While additional widespread heavy snow accumulations are not
expected after 12Z, strong gusty winds will continue, extending
hazardous travel continues across the region on Thursday.

...Southern Rockies...

As the low over the Plains lifts out to the northeast, models
continue to show trailing energy dropping into the base of the
trough, supporting some light to moderate snows across the
southern Colorado and northern New Mexico ranges on Thursday.
