.SHORT TERM...(Tonight through Wednesday night)
Issued at 146 PM CDT Mon Jul 24 2023

Weak upper level shortwave visible in water vapor seems to be
inducing some weak large scale ascent producing convergence from
about Poplar Bluff to Evansville, with a cu field stretching from
current severe storms in SEMO into a pretty obvious low level vort
over west central Indiana. Mid to low 70s dewpoints and 90 degree
surface temps give us about 2500 J/kg of MLCAPE with 1100 DCAPE
and 25 degree theta-e differences. This is allowing for severe
wind gusts, with CGI gusting to 53kts about an hour ago. 0-6km
shear is weak but may just be sufficient to allow for some storm
organization and upscale growth as this complex moves southeast.
Also expecting additional convective initiation up the cu line
into EVV by later this afternoon. Surface moisture/instability is
not quite as strong there so the severe risk may be muted a bit.

Guidance likes the idea of another MCS developing overnight along
the moisture gradient produced by this mornings activity and
raised pops through the overnight and late morning. By mid-
afternoon upper level ridging is progged to have moved more
overhead which will work drier 850-700mb air into the area which
is expected to mix down and cut our available convective
instability, leading to a dry and warm afternoon. Warm and dry
conditions are forecast for Wednesday as ridging becomes more
established overhead.

.LONG TERM...(Thursday through Monday)
Issued at 146 PM CDT Mon Jul 24 2023

For the longer term period tamped winds and max temps down a
little bit. Southwest flow should eventually start to bring in
more low level moisture and added some slight chance pops Saturday
and Sunday when there is some suggestion of a bit of a east to
west boundary setting up over the area. Think based on what I'm
seeing that "more precip" will win out over "higher temperatures"
and kept the heat index values below advisory criteria despite the
500mb temps starting to nose up into range for that.

.AVIATION...
Issued at 1219 PM CDT Mon Jul 24 2023

Convection over SEMO will continue to the south at its current
rate but additional development is possible further east in the
afternoon heat, particularly for CGI/PAH. Smaller risk for
afternoon storms elsewhere but too low for TAF mention. Current
position of pooled moisture makes fog more likely tonight at sites
like MVN/OWB/EVV and vicinity but will need to watch all sites for
potential.
