.DISCUSSION...
Issued at 334 PM CDT Mon Sep 1 2025

An area of low pressure currently sits over southeastern Nebraska,
with continued shower activity across primarily southeastern
Nebraska, although a few light returns are being picked up on radar
across western Iowa. Moderate rainfall may be possible at times,
causing some reductions to visibility. Shower activity will end
northwest to southeast late this afternoon/early evening as the
low slides southeast into northern Missouri.

Light and variable winds are expected tonight into Tuesday morning.
This, combined with cool temperatures and recent moisture will pose
a concern for some fog development across the region, but
particularly for low-lying areas.

Tuesday, will be fairly quiet with dry conditions expected as we
come under northwest flow, with a broad upper trough to the east.
Temperatures for this time of the year range from the low to mid-80s
for highs and the mid-50s to low 60s for lows. Tuesday`s expected
highs will range from the mid-70s across western Iowa and areas
along and south of the Hwy 92 corridor to the low 80s along the
NE/SD state line.

A cold front slips south into the region on Wednesday, bringing
another shot of cooler air. Expected highs will range from the mid-
60s in the north, to the mid-70s along and south of I-80. Low
temperatures Wednesday night/Thursday morning will fall into the low
to mid-40s. Shower and thunderstorm chances (20-50%) will return to
the forecast for the daytime hours, tapering off from north to south
in the evening.

Thursday brings a brief warm up and dry conditions before another
cold front arrives on Friday. The cool down back into the 60s will
be short-lived. Expect a gradual warming trend heading into the
weekend, with highs in the 60s and 70s and lows in the 40s and
50s.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 634 PM CDT Mon Sep 1 2025

MVFR ceilings should continue to exit early in the period with
clearing skies giving way to fog development overnight,
especially north of Interstate 80. The big question will be how
far south fog extends and exact timing of development and
dissipation. For now, included restrictions at OFK (2SM, TEMPO
1/2SM) and OMA (3SM) with a 6SM mention at LNK where clouds may
linger a little longer overnight. Would expect some locations
to see 1/4SM or less, but confidence in that happening at TAF
sites is low right now. Fog should start to dissipate toward 15Z
with FEW to SCT clouds 2000-3000 ft lingering through the
remainder of the TAF period. Winds should generally remain 5 kts
or less and somewhat variable overnight, but will become
southwesterly Tuesday.
