.DISCUSSION...
Issued at 319 PM CST Mon Nov 17 2025

Cloud cover has spread across eastern Nebraska and western Iowa
as a low pressure system approaches, currently located over the
Nebraska Panhandle. Scattered showers have developed along the
warm front along the Missouri River north of Omaha. Marginal
elevated instability has led to isolated thunderstorms along
this boundary. We`ll continue to see chances for isolated
thunderstorms as showers expand across the area this afternoon.
A cold front will move through tonight shifting winds to
northerly and bringing back in seasonably cool air.

Cooler temperatures on Tuesday with highs in the mid 40s to mid
50s across our area. Dry weather returns as a ridge moves
overhead with surface high pressure in place. Ridging amplifies
over the southeastern CONUS midweek leading to strengthening
southwesterly flow across the central CONUS. A shortwave will
move through on Wednesday bringing a shift back to southerly
surface winds which will warm afternoon highs back up into the
mid 50s to low 60s Wednesday afternoon.

Late in the week we see the strong upper-level trough over the
western CONUS eject a strong Low east toward the Rockies as a
second strong Low takes its place. This Low will weaken as it
approaches, expected to pass south of our area across Kansas and
Missouri. This would be a great snow scenario if we were colder,
but with afternoon highs still in the 50s on Thursday, and 40s
on Friday, we should stay too warm for any potential snow.
Expect a cold rain to start to move in from the south on
Thursday, staying mainly south of I-80 through the afternoon.
Rain chances expand northward Thursday night into Friday, coming
to an end Friday evening before the sub-freezing temperatures
arrive.

Ridging moves back in over the weekend, with a warm front
bringing temperatures back up into the mid 50s for Saturday and
Sunday. The next significant weather system looks to arrive
around Monday next week. Ensemble still not showing any
significant chance for snow even with this system.

The Climate Prediction Center is forecasting the potential for a
Sudden Stratospheric Warming Event toward the end of November,
bringing in colder temperatures around the second half of next
week into early December. We are already seeing colder
temperatures showing up toward the end of our forecast
models/ensembles supporting this scenario. With this we could
potentially see chances of snow start to increase, with
ensembles starting to ramp up chances the weekend after
Thanksgiving.

Showers and storms will exit early in the period with MVFR
ceilings still expected to push in from the northwest overnight
and through Tuesday, though slower than previously thought. Fog
has also developed across central Nebraska and may try to sneak
eastward toward OFK, but latest guidance suggests it will stay
just west, with just ceilings falling to IFR. Some recent
guidance also suggests fog could develop early Tuesday in areas
that received rain this evening, but currently think incoming
dry air and decent winds aloft will keep it patchy if it does
develop. Finally, winds will continue to turn counter-clockwise,
settling in at northerly early in the period, with speeds on
either side of 10 kts during the day.
