.SHORT TERM /THROUGH TONIGHT/...
Issued at 139 PM CDT Fri Aug 29 2025

A corridor of deeper moisture across extreme southwest Missouri
and southeast Kansas has allowed low and mid level clouds to
stick around into the afternoon. To the east, only a few high
clouds can be seen on satellite.

Overnight, models disagree on any fog potential across the
region. A minority of the guidance depicts a shallow layer of
near-surface moisture under the inversion that would promote fog
development, but most tend to show a drier, fog-free solution.
NBM probabilities of visibilities less than 5 SM are around 20%
across southwest Missouri and southeast Kansas.

.LONG TERM /SATURDAY THROUGH FRIDAY/...
Issued at 139 PM CDT Fri Aug 29 2025

Some Rain Chances Late this Weekend:
This weekend, global models depict a fairly stagnant upper-
level pattern with a ridge across the western CONUS and a trough
across the east, leaving Missouri under northwest flow aloft. A
series of shortwaves transiting the Plains will introduce some
rain chances late this holiday weekend. For Sunday, a weak
impulse looks to initiate convection across portions of
Nebraska, Kansas, and Oklahoma that will gradually approach our
CWA during the morning. This activity largely looks to stay
west of Springfield, closer to the source of lift.

On Monday, ensembles tend to show a more prominent upper-level
disturbance diving southeast out of the northern Plains, with
the corresponding surface low and attendant front translating
through southwest Missouri. This system will likely provide the
highest rain chances for most locations this weekend. With
global models showing at least a few hundred Joules of
instability, a few thunderstorms will be possible as well. No
severe weather is expected with this activity. Ensembles have
trended toward a slower solution with the progress of the
aforementioned shortwave. If the low pressure system lingers
over the area, rain chances may persist into the day Tuesday as
well, particularly across south-central and southeast Missouri.

Below-average Temperatures to Continue:
Ensemble solutions begin to diverge more significantly by
Thursday and beyond. Largely, they agree that a cooler airmass
will intrude southward over the Missouri Ozarks, but they
disagree on the exact magnitude. ENS members favor a cooler
solution and tend to dig the trough slightly farther south and
west, while GEFS members tend to be warmer and are a bit farther
east in their trough positioning.

The CPC 6-10 Day Temperature Outlook still strongly favors (80%
chance) below-average temperatures through the beginning of
September.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 647 PM CDT Fri Aug 29 2025

Fog may be possible tonight, but should be less dense and less
coverage than last night due to a layer of mid to high level
clouds over the area. Best chances are at KJLN. For KGGB, fog
potential was too low to include in this TAF issuance. Seeing
potential for 4-5 SM visibilities in the most pessimistic
guidance.

Otherwise, look for sustained broken to overcast high level
clouds on Saturday.
