.DISCUSSION...
Issued at 336 PM CDT Thu Sep 18 2025
Patchy fog has developed across areas primarily along and east of
the Missouri River. Visibility reductions of under one mile are
expected at times. If needing to travel, use caution.
The forecast period starts out with an active weather pattern over
the Central Plains. An upper ridge will be in place over the Bighorn
Mountains and the Rockies. An upper trough will be situated over
eastern Nebraska, eastern Kansas, western Iowa, and northwestern
Missouri. A closed upper low over the Dakotas this morning will
slide to the southeast through the day, moving across the forecast
area this afternoon. Heading into the afternoon, there will be a 20-
30% chance of showers and thunderstorms beginning west to east.
Chances increase (30-60%) heading into the evening and overnight
hours before tapering off Saturday morning. Expect some fall-like
temperatures with highs ranging from the low to mid-70s for ares
along and north of I-80 and the mid to upper 70s for areas south.
Lows will be primarily in the 50s.
A series of shortwave troughs and disturbances will drop into the
CWA through the weekend and into Wednesday. Periodic chances for
showers and thunderstorms are expected over the course of the next
several days. As we start getting into Tuesday and Wednesday, there
is some significant deviance in where models bring a storm system.
Some models track the storm down into Kansas and Oklahoma on
Wednesday morning. Contrasting this, the GFS brings a low through
the Nebraska Panhandle before having it become an open wave.
This solution also lags considerably behind the ECMWF.
Saturday begins a three-day warming trend, with highs in the 80s
returning to the forecast area on Monday. Lows will be primarily in
the 50s and 60s.
Uncertainty continues the further out in the forecast we get with
many interpretations of what will actually transpire.

A deck of MVFR ceilings remains in place over northeast NE,
grazing KOFK and KOMA, which is expected to gradually improve
this afternoon. A cluster of thunderstorms is pushing into
eastern NE and will continue into the evening. A few scattered
showers may approach KLNK (40% chance) this afternoon before
the heavier cluster pushes in this evening. The highest chance
(50-70%) of impacts is at KLNK this evening, with scattered
showers and storm possible over KOMA (40% chance) into the
evening. Storms will likely remain south of KOFK. Winds will
shift from northwesterly to southwesterly as the system pushes
into the area this evening.
Fog is expected to develop overnight across east-central
Nebraska. MVFR conditions are expected across all terminal, with
IFR and potentially LIFR at KOFK during the mid-morning hours.
Fog will gradually improve after 12-14Z.
