.DISCUSSION...
Issued at 210 PM CST Wed Feb 25 2026

Narrow band of snow continues to make progression east-southeast
across the CWA early this afternoon. Been making adjustments to PoPs
throughout the day to account for this. Also watching another area
of rain showers across western SD, taking aim for the southwest CWA
and may have to make some adjustments there as well. Looking at web
cams where it has snowed, it would appear the most anyone received
was maybe a few tenths to a half inch as the band of snow has been
fairly progressive.

Tonight, a warm front will move eastward across the area, with
milder temperatures in its wake for Thursday and even into Friday.
925mb temps warm to as high as +5C to +10C across the area during
this time. We will also enter into some breezy/windy conditions both
days, with west-northwest winds gusting between 25 and 35 mph for
most areas. Humidity values drop to around 25 to 35 percent across
central SD Thursday and Friday afternoon, so Grassland Fire Danger
values bump up into the "Very High" category those days. For the
time being, it appears criteria for wind and/or fire wx headlines is
not met.

Focus then shifts to the snow potential Friday night into Saturday.
Colder air begins moving back southward over the region on Saturday
and lingers through the weekend as highs drop back down into the
teens, 20s, and 30s. Models still show a band of accumulating snow
running west to east across the CWA. Seems like a case (at least for
now) where most accumulations are less than 4 inches. Probability
for receiving 2 inches or greater is only about 15-35 percent from
KMBG through KATY. Current forecast shows a general 1 to 2 inches
over said region, but will be refining this in the coming days.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 521 PM CST Wed Feb 25 2026

Terminals KABR,KATY,KPIR,KMBG

There is a swath of MVFR stratus working across northeast South
Dakota (currently over KABR). This stratus may work over KATY, as
well, over the next 6 hours, as it makes its way southeast and out
of the region later this evening/overnight. Have used a
combination of satellite trends and short-term guidance to try and
time the end of MVFR conditions at KABR this evening, and the
start/end to MVFR conditions at KATY. Otherwise, all four
terminals are forecast to be VFR during the TAF valid period, as
south winds generally at or less than 10 knots switch around to
the west by morning and increase to 15 to 20 knots with gusts up
to 30 knots.
