.DISCUSSION...
Issued at 159 PM CST Sat Jan 24 2026

Clear sky conditions this afternoon, with temperatures gradually
creeping above 0 degrees across much of the area. As low clouds move
in tonight, there will be some chances for some light snow showers
as well. Confidence is low on the exact coverage and timing, but the
greatest chances to see measurable snow are over central and north
central South Dakota overnight tonight into early Sunday morning.
Areas that do see snow are not expected to receive more than a
couple of tenths of an inch in accumulation. By Sunday morning, a
high pressure center begins to build into the area, pushing the snow
chances out to the south by the end of the morning.

Cold temperatures are expected to stick around for the next couple
of days, and overnight wind chills may approach Cold Weather
Advisory status both Sunday and Monday in the early morning.
Sunday`s chances appear more marginal at this point, with high-
resolution ensembles showing chances to reach -30 degrees only at
roughly 10% over a small area along the SD/ND state line. As such,
no headline is expected for Sunday`s overnight cold. Stronger winds
gusting to 20-25 mph Sunday night into Monday morning look to
potentially provide broader coverage of Advisory criteria wind
chills, and a headline will definitely need to be considered with
future forecast packages. However, no headline will be issued at
this time.

The broad pattern of a ridge over the western CONUS and a trough
over the eastern CONUS is expected to continue through most of next
week, catching the ABR forecast area in the transition zone between
the two. This setup will support the continuation of temperatures 5-
10 degrees below late-January normals, with the exception of Monday
where a brief warm up to near-normal is expected. The extended
period looks mostly dry, with some possible snowfall coming mid-week
thanks to an upper-level jet streak riding down the front side of
the ridge. At this point, NBM probability of measurable snow reaches
about 50%, and probability of 1" sits at roughly 20% for this
clipper system. Otherwise, little of note in the extended period at
this time.

VFR conditions initially will give way to MVFR CIGs later tonight
into early Sunday morning. There may be patches of -SN with these
lower clouds as well, with potential for MVFR VSBY. Will handle
this with a PROB30 for the time being. Forecast is for a return to
VFR conditions late in the TAF period. Southeast surface winds
early this evening will gradually switch to north-northwest by
Sunday.
