.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.
