.DISCUSSION...
Issued at 254 AM CST Mon Feb 2 2026

TODAY & TONIGHT: A slightly cooler day ahead! Taking a look across
the area, a dreary start continues as lower-level clouds (stratus)
continues to blanket the area this morning. Similar to yesterday, we
should keep overcast skies around for most of the day. However, our
surface winds will be a lot lighter than yesterday. Otherwise, the
first half of the day will remain quiet as temperatures peak in the
upper teens to mid 30s for the day with the coolest conditions north
of a Huron to Sioux Falls to Storm Lake, IA line. By the second half
of the day, we`ll see another clipper wave swing across the Northern
Plains by late afternoon promoting increased snow chances (20%-30%)
from the early evening into the overnight hours. With QPF expected
remaining below 0.10" of an inch, most areas can expect a dusting or
less with the potential for light snow to transition to pockets of
freezing drizzle and/or flurries overnight. Otherwise, most of this
activity should gradually dissipate into the start of Tuesday as
temperatures decrease into the low double digits to low 20s for the
night.

TUESDAY-THURSDAY: Looking into Tuesday, a surface high will slide
through the area keeping any developing precipitation chances
confined to the western and central portions of SD. Otherwise,
temperatures will continue to hover near to just above normal
thresholds with highs mainly in the 20s to mid 30s through
Wednesday. By Thursday, broad northerly flow aloft will help usher
in a mid-level ridge. Increasing warm air advection (WAA) on the
backside of the ridge will help temperatures approach their warmest
points for the week with highs mainly in the 40s to low 50s expected.
Otherwise, a dry cold front will swing through the region by late
Thursday slightly decreasing our temperatures into the weekend.

THE WEEKEND: Heading into the weekend, upper-level ridging over the
western conus will begin to break down shifting us back to
northwesterly flow aloft. The pattern will remain active aloft with
another weak wave swinging through between Saturday and Sunday with
limited precipitation chances (<10%). However, temperatures will
continue to hover in 30s to mid 40s through Sunday as the quieter
conditions continue.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 510 AM CST Mon Feb 2 2026

Mainly MVFR conditions will continue this TAF period. Taking a
look at satellite imagery, MVFR to IFR stratus continues to sit
over the area this morning. Not expecting much chances across
the area throughout the day with mainly MVFR cigs continuing.
Light snow will return by early evening potentially promoting
occasional IFR vsbys. However, it will be more of a quick burst
than prolonged conditions. Otherwise, lighter surface winds will
continue into Tuesday to end the TAF period.
