.DISCUSSION...
Issued at 320 AM CDT Sat Sep 20 2025
A boundary is currently stalled across south-central and
southeastern Nebraska. For the past several hours, showers have
developed along the boundary and moved east. These showers have been
training across southern Seward, central Lancaster, southern Cass
(NE), Fremont, and Page counties. Pwat values are in the
1.0-1.1" range. Rivers and creeks in the area have not shown
significant rises and the ground in these areas is not currently
saturated, so at the present time, flooding is not an immediate
concern. However, the potential for some minor flooding should
storms continue to train will be something to monitor over the
next few hours.
In addition to the potential for precipitation, fog will be a
possibility for portions of northeastern Nebraska and western Iowa.
Light winds, residual moisture, and clear skies will help with
development in these areas. Visibilities may fall below one mile or
less in some locations, with locally dense fog possible.
The forecast period starts with split flow across the western and
central U.S. The southern split has a ridge axis over Colorado and
New Mexico with a trough off the coast of southern California. The
northern split has a ridge over the PACNW and a trough over
Nebraska, Missouri, and Illinois. Over the next few days, several
disturbances will move through the broader pattern, bringing a few
chances (20%) for showers and storms. The next best chance (30-60%)
for showers/storms will be Monday evening through Tuesday with
additional chances (20-30%) on Wednesday. This will be dependent on
the track and timing of a disturbance sliding into the region from
the Rockies. Uncertainty remains in the timing of the system. Models
have come into a little better agreement with the location, bringing
the system through extreme southwestern Nebraska and north central
Kansas. Temperatures will be primarily in the 70s and 80s each day
for highs with lows in the 50s and 60s.
Heading into the latter portions of the forecast, models are showing
continued split flow over the CONUS. A ridge is expected to shift
east over Nebraska and the Dakotas. Temperatures are currently
forecasted to be in the 70s for highs and the 50s for lows.

period of temporary MVFR ceilings early this afternoon (namely
at KOFK), prevailing VFR conditions will continue into tonight.
Winds will remain light through the forecast period, which will
support fog development toward daybreak Sunday morning,
