.DISCUSSION...
Issued at 200 AM CDT Tue Sep 2 2025

Nighttime microphysics satellite imagery depicted widespread
stratus over southern Nebraska into northern Kansas at midnight.
This stratus is expected to spread southwest into much of
SW KS through sunrise Tuesday. Widespread fog is not
anticipated, but this will be monitored given the continued
moist soils and boundary layer.

Once the morning stratus erodes, Tuesday promises to be a
fantastic late summer day with sunshine, mild temperatures in
the upper 70s and lower 80s, and light north winds. All of SW KS
will remain dry through Tuesday night.

Midlevel ridge axis will remain parked over the Great Basin and
Rockies Tuesday and Wednesday, maintaining NWly midlevel flow
over SW KS. An unseasonably strong 547 dm closed low is forecast
near Lake Superior 7 pm Wednesday, with the associated cold
front arriving in SW KS Wednesday afternoon. Exact frontal
timing will determine precise temperatures, but current thinking
is SWly downslope and prefrontal compression will make for a
much warmer afternoon ahead of the advancing cold front. 00z NAM
supports this warmer solution Wednesday with a slower front
advancement. Many locations south of the front at peak heating
will warm into the lower 90s, with the warmest 00z MAV guidance
suggesting highs in the mid 90s. Green vegetation and standing
water will hold temperatures down a few degrees from the warmest
guidance. Convergence along the advancing cold front is
expected to encourage thunderstorm development across/near the
southeast zones Wednesday evening, where SPC 5-15% wind/hail
probability is appropriate. CAPE/shear combination will be
supportive of at least marginal supercells over the southeast
counties Wednesday evening.

Thursday will be a few degrees cooler behind this first weaker
cold front, but south winds will return quickly Thursday, with
afternoon temperatures remaining in the lower to mid 80s. A much
stronger cold front remains consistently timed in the guidance
for Friday morning. Models depict NEly 850 mb winds of 20-30
kts, and expect post frontal northeast winds Friday to be
stronger than NBM guidance. Shower and thunderstorm generation
on this cold front is rather inconsistent in the model guidance,
but NBM pops currently align with the drier solutions. Certainly
Friday will be much cooler, the question is how much cooler,
with ECMWF cooling 850 mb temperatures to 11-13C range. NBM
continues to trend cooler Friday, now down to the lower 70s, but
60s may be more realistic if stratus holds much of the day.

A cool 1020 mb Canadian surface high is forecast to build south
into the central plains Saturday morning, delivering the coolest
temperatures of the young fall season. Lower 50s will be common
sunrise Saturday, with the typically colder locales falling to
the upper 40s.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 500 AM CDT Tue Sep 2 2025

Satellite imagery at 10z Tue depicted stratus northeast of a
GCK-DDC-P28 line, advancing slowly southwestward. Stratus will
continue to expand southwest to impact GCK/DDC over the next few
hours, while IFR ceilings continue at HYS. Stratus is not
expected to reach LBL this morning. All stratus will erode by
around 18z, with VFR/SKC expected for the remainder of this TAF
period. Light north winds prevail Tuesday, followed by light and
variable winds tonight.
