.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 358 AM CST Mon Nov 17 2025

Currently, surface low pressure is located across northeastern
Colorado, with broad southeasterly flow across the area ahead of
this feature. Within this broad warm advection regime, temperatures
remain in the upper 30s to low 40s early this morning. Aloft, an
upper level shortwave is centered over northern Utah.

For today, the aforementioned upper level shortwave is expected
to eject eastward aloft across western Nebraska, becoming a
closed low by this afternoon. This upper low then tracks east
across the state by tonight, with the associated surface low
tracking along the Nebraska/Kansas state line through the day.
The evolution of precipitation today follows similar thinking of
the previous forecast, with much of the area remaining devoid
of rain through much of the day. This is due to the dry slot
translating across the area, keeping the bulk of deformation
axis precipitation off to the north across South Dakota.
Additional precipitation is expected near and ahead of a warm
front across eastern and northeast Nebraska this afternoon as
well, largely east of the area. Still, areas near and north of
Highway 20 may see scattered rain showers today, and will
maintain at least a chance mention (25-40%) of rain this
afternoon. A low chance (10-15%) exists for wraparound precip
across the Sandhills as the low begins to move east, though
confidence remains low. Regardless, amounts are expected to
remain light across the entire area today, generally ~0.10 or
less. As the low begins to exit off to the east tonight, any
precipitation will quickly end from west to east.

Quieter conditions return for Tuesday, as shortwave ridging
translates across the area in the wake of today`s low. Weak cold
advection and persistent cloudiness will keep temperatures in the
upper 40s to 50s, with the coolest highs east of Highway 83. This is
in closer proximity to cool surface high pressure dropping into the
upper Midwest.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 358 AM CST Mon Nov 17 2025

By Wednesday, a deep upper low will begin to move into the Four
Corners, with southwest flow establishing aloft across the Plains.
This leads to lee cyclogenesis Wednesday morning across eastern
Wyoming, with southerly flow returning across the area. This
increasing warm advection boosts highs on Wednesday afternoon
briefly back into the low 60s.

Attention then turns to the next system of note, as the
aforementioned upper low begins to eject across the Rockies
Thursday into Friday. A notable southward trend in the
deterministic guidance suite, more in line with both the
EPS/GEFS mean, has begun to favor the I-70 corridor across
Kansas with the greatest QPF. This unfortunately leaves much of
the area north of a sharp cutoff in precipitation amounts.
Should this evolution occur, limited accumulations near and
south of I-80 are still possible, though little to nothing would
be expected further north. Ensemble means look to be in good
agreement, with ~30-50% probabilities of >0.1" along I-80 to as
much as 60-80% along HWY 6 Thursday into Friday. Though at least
light accumulations still look possible, confidence has begun
to wane in impactful rain amounts across the area late week.
Wintry precipitation types would also be possible early Friday
morning across southwest Nebraska, though this will remain low
confidence until the track of the system becomes more clear.
Drier conditions then return into next weekend, with
temperatures remaining slightly above average in the 50s.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 525 AM CST Mon Nov 17 2025

Low stratus is expected to overspread central and northern
Nebraska this afternoon, with widespread MVFR CIGs expected.
Additional low stratus then expands into the Sandhills tonight,
with CIGs lowering to low end MVFR/IFR for terminals north of
I-80. Scattered rain showers are also possible this afternoon
and evening, with brief MVFR visibilities possible.

A frontal boundary stalls near Highway 83 today, with west-
northwest winds (Gusts of 25 to 30 kts possible across far
southwest Nebraska) west of Highway 83 and southeast winds (10
to 15kts) to the east.
