.DISCUSSION...
Issued at 257 PM CDT Tue Aug 19 2025

This afternoon a boundary reside across the extreme southwestern
CWA. A cluster of storms located in Topeka is expected to travel
southeast along this boundary and may persist long enough this
evening to bring a few stronger storms capable of gusty winds and
heavy rain to the southwestern CWA. Conditions are expected to dry
out tonight into tomorrow as a surface ridge of high pressure looks
to build south into the area from the Upper Midwest. This may lead
to some light fog across the area tomorrow morning. This will also
return temperatures to nearer seasonal normals tomorrow with lower
humidity with highs in the mid 80s to lower 90s. The surface ridge
of high pressure will remain in control over the area on Thursday
with highs in the 80s. Friday, the surface ridge will slide east of
the area as a upper level ridge centered over the Four Corners
region attempts to build eastward providing subtle height rises.
This will allow highs to rise back into the mid 80s to near 90.

The next chance for precipitation will arrive in the area Friday
night as a upper level trough moving through the northern tier
states acts to flatten the upper ridge attempting to build into the
region as forces a cold front into the forecast area. Strong storms
capable of gusty winds may be possible as modest instability between
1000-1500J/Kg of MUCAPE will be available however, shear will be
weak. This frontal passage will bring cooler temperatures for
Saturday with highs in the upper 70s to mid 80s. A surface ridge of
high pressure will then to look to build into the area Saturday
night into Sunday ushering in early Fall-like temperatures for
Sunday with highs in the mid 70s to lower 80s. A reinforcing
surface ridge will build south from the northern Plains on Monday
under northwest flow aloft bringing another early Fall-like day with
highs in the mid to upper 70s.

Issued at 1053 PM CDT Tue Aug 19 2025

Currently VFR at all terminals with light ENE winds. Fog, with
the potential for areas of dense fog, may develop by around 9z
Wednesday, primarily across NW Missouri. As such, have brought
VIS down to 4SM at STJ by 9z, with a TEMPO group for 1SM between
9z and 13z Wednesday. At MCI, have a TEMPO group for MVFR VIS
also between 9z and 13z. Fog should mix out by around 14z
Wednesday, returning flight categories to VFR. Light ENE should
persist through the period.
