.DISCUSSION...
Issued at 150 PM CST Fri Mar 6 2026

At 2 PM CST, skies are cloudy and temperatures are in the 20s. Winds
are northwest at 15 to 25 mph with gusts up to 35 mph. A preliminary
deformation band that formed earlier this morning across western
into north central South Dakota, started producing snowfall all the
way to the ground between 10 AM and 11 AM this morning and now, a
bonafide deformation zone banded snow event is under way. The parent
low for this is still observed down across Colorado (associated
surface low has emerged and moved out to over central KS). Most
webcams are not showing much more than a half inch to an inch of
snow so far. But, much of the band of snow is occurring just outside
of webcam purview, and based off METARS underneath the heaviest
portion of the band (1/2sm to 3/4sm in snow), fully expecting this
thing to end up generating a swath of 3 or more inches of snow,
"with locally higher amounts possible". A short-fuseed Winter
Weather Advisory has been posted for this phenomenon until 8 PM CST.

Otherwise, the models/guidance continue to tighten their focus on
the rest of today`s/tonight`s winter weather event across mainly
northeast and east central South Dakota into west central Minnesota,
with slightly less snow amounts (now down to generally an inch or
less) but seeing the ice accumulation amounts coming up a little bit
(now up to between 0.10-0.20 inch of ice across parts of the Prairie
Coteau into west central Minnesota and continuing to see the timing
of all this delayed to the point that almost all of the freezing
rain, sleet and snow doesn`t get going across the eastern forecast
zones until ~23Z or later.

No noteworthy changes showing up in models/guidance for Saturday
through Friday of next week.
