.DISCUSSION...
Issued at 147 PM CDT Tue Sep 23 2025
A 500 mb vort max over Colorado associated with a broad trough will
bring more periods of active weather across the FA through
Wednesday. The next area of rain and embedded storms is now over
SEMO and will continue to push east into western Kentucky through
this evening when the 12z CAMs show convection peaking. SPC
maintains a marginal risk of severe weather with isolated damaging
winds being the main concern. However, cloud debris associated with
morning convection has help to limit destabilization to some extent
with only 1000 to 1500 J/kg of SBCAPE now progged by the RAP13
downstream. Give 25 to 30 kts of sfc-3km shear and low level lapse
rates between 6.0 to 7.0 C/km, a brief strong to severe storm
through this evening still cannot be ruled out.
The 12z CAMs remain split on the intensity of a second round of
storms tonight, with the HRRR and 3km NAM being more robust as a
weak sfc low deepens along I-64 helping to advect in even more
moisture. Unlike the first round, these storms should be more
elevated posing mainly a heavy rain concern. Regardless, heavy
rainfall rates due to PWATs between 1.5 to 2.0 inches will be
capable of causing localized flash flooding with typical runoff
issues in low-lying locations. As a amplified longwave trough
approaches from the west Wednesday and provides robust PVA, one
final round of showers and storms will be possible Wednesday
afternoon into Wednesday evening, posing another marginal risk
of severe storms over southwest Indiana and western Kentucky.
As the aformentioned trough pushes east on Thursday, lingering
showers will remain possible before dry weather conditions settle
over the region for the upcoming weekend. Temperatures will be
slightly below normal through the remainder of the week before
turning seasonable by Saturday.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1205 PM CDT Tue Sep 23 2025
Several impacts to the terminals over the next 24 hours as a
disturbance moves across the region. Two rounds of showers and
storms will be possible this afternoon into the evening and
again tonight. Stronger storms with the first round will be
capable of causing gusty winds while heavy rainfall is the main
concern overnight. After pcpn tapers off early Wednesday
morning, low ceilings and patchy fog will be probable with
LIFR/IFR reductions. Gradual improvement to MVFR occurs towards
the end of the period.
