.DISCUSSION...
Issued at 241 PM CST Fri Nov 28 2025

...Synopsis...

Large, positively tilted trough continues to dig down over the
Rockies, coming out into the Plains tonight. The main embedded
shortwave energy will be to the south across the Central Plains
into IA/IL. Main low will be well to the south, but inverted
trough will extend into our southern counties for a while
tonight and tomorrow. The surface high nudges in for Saturday
night, with northwesterly flow aloft. The northwesterly flow
continues into next week, with several weak reinforcing
shortwaves dropping heights and bringing cold air. The weak
shortwaves also could bring some periodic light snow, although
confidence is low on any impacts.

...Accumulating snow tonight and Saturday in the south...

Already starting to get some very light radar returns over our
far southwestern counties, but web cams show nothing reaching
the ground yet. There is decent agreement with the CAMs on
better radar returns entering after midnight. The HREF
probabilities of an inch or more are above 50 percent for most
of southeastern North Dakota into far west central MN, mainly
southwest of a Valley City to Kindred line. Think accumulating
snow is likely. Probabilities of 3 or more inches, drop down to
a small area of around 35 percent near the SD border, with
probabilities of over 4 inches around 20 percent. At this point,
best chances look to be in the 1 to 3 inch range, with just a
slight chance for advisory criteria. Still not certain enough
for headlines at this point as best chances for getting up to 3
or 4 inches are fairly limited in area. Winds will also not be
an issue, remaining under 10 mph.

...Cold temperatures and low chances for snow into next week...

ECMWF EFI has a pretty good signal for colder than average
temperatures as we move into next week, and this fits the mean
synoptic pattern. Not as strong of a signal for precipitation,
although the ensemble members do show various shortwaves moving
through, particularly towards the end of the period. Cold is
certain, any winter impacts from snow less so.

TAFs bouncing between MVFR and VFR, as well as between -SN and

the afternoon and evening. Should see more widespread MVFR
ceilings later tonight, as well as more light snow at KFAR and
KDVL. East winds under 10 kts will become light and variable,
then steady out of the north by the end of the period.
