.DISCUSSION...
Issued at 107 PM CST Fri Nov 21 2025

Tonight through Sunday...

Water vapor imagery and objective analysis this afternoon shows a mid-
level shortwave moving across the central Plains, with an associated
surface low over central Kansas slowly drifting east. A band of
precipitation north of the low continues to bring light rain to
southeast Nebraska and southwest Iowa. Rain will steadily diminish
from north to south through the afternoon, with totals generally
topping out around 0.25-0.50" near the Nebraska-Kansas border.
Persistent cloud cover and northerly low-level flow will hold
afternoon temperatures in the chilly 40s.

Between the departing low to the south and another surface low near
the North Dakota-Canada border, a weak front will slide through
tonight into Saturday morning, shifting winds to the southwest.
Guidance does hint at the possibility for patchy fog again Saturday
morning. However, winds increase just enough behind the front with
model soundings bringing gusty winds just above the surface as
well. Therefore, any fog will likely be very patchy and
constrained to wind protected areas in southeast NE and
southwest IA.

Clearing skies and a modest pattern change will allow Saturday`s
highs to climb into the low 60s, about 10-15 degrees above the
climatological average for mid- November. Although a weak cold
front will sweep through early Sunday as the northern system
passed by, temperatures will remain largely unaffected, with
southerly flow quickly returning and highs again reaching the
low 60s. Overall, the weekend looks mild, dry and pleasant.

Monday and Beyond...

By Monday, the closed mid-level low currently positioned along the
California-Baja coast will slingshot northeast toward the region,
bringing our next chance for precipitation. PoPs move in Sunday
night and peak around 60-80% Monday morning before diminishing from
west to east through the afternoon. The bulk of the precipitation is
expected to fall as rain, with temperatures largely holding in the
40s and 50s. Cooler air arrives Tuesday on the backside of the
departing low, and a handful of EPS/EPS-AIFS ensemble members
(roughly one-eighth) suggest the potential for some light snow in
northeast NE as the system exits. At this time, the probability of
impacts appear low, but it`s something to watch. High Tuesday will
generally reach the 40s, accompanied by gusty northwesterly winds.

By midweek, a mid- to upper-level trough sweeping across the
northern Plains will send a reinforcing shot of cold air into the
region, dropping high temperatures into the 30s and low 40s through
the remainder of the work week, with overnight lows in the teens and
20s. Long-range guidance also hints at a band of light snow Thursday
into early Friday, though GEFS and EPS/EPS-AIFS members show
considerable spread in both placement and intensity. For now, PoPs
remain below 20%, but the situation will be monitored. A more robust
mid- to upper-level trough is expected to arrive next weekend,
bringing better chances for snow; however, ensemble solutions
continue to vary widely on where snowfall may set up. It will be a
period to keep an eye on.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1026 AM CST Fri Nov 21 2025

MVFR with patchy areas of IFR ceilings continue across southeast
Nebraska late this morning as rain showers persist. Impacts will
mostly be constrained to KLNK, where MVFR ceilings and rain
showers continue. While a few light rain showers may reach KOMA,
generally VFR ceilings will prevail at KOMA and KOFK. Showers
will clear from north to south through the after, with a return
to VFR conditions expected at KLNK by mid-afternoon. Lingering
clouds at 6000-9000 ft will gradually break up and improve
through the afternoon and evening. Northeasterly winds will
remain at 7-10 kts through the period, shifting to southwesterly
overnight.
