.SHORT TERM...(This evening through Sunday)
Issued at 203 PM CDT Sat Jul 29 2023

A thunderstorm complex was bringing damaging wind to areas north
of the CWA early this afternoon and stretched from near Columbia
northward into north central MO as of 1 pm. Outflow from this
complex was pushing into our CWA from Morgan county to near
Pittsburg Kansas as of 1 pm. In addition to the potential of storm
redevelopment along the outflow boundary as it moves into a more
unstable environment, the outflow itself may produce wind gusts of
30 to 40 mph in central MO. Some of the storms that develop this
afternoon into this evening may be capable of producing damaging
wind gusts of 60 to 70 mph and hail to the size of quarters in
central MO where a severe thunderstorm watch is in effect until 7
pm. While 0-6km shear is not impressive in our CWA, the daytime
heating as eroded the CAP with 3000-4000 j/kg of CAPE.

Storms should weaken and erode this evening with main remnants
over the eastern CWA.

Lows tonight will remain warm from the upper 60s to mid 70s.

Another potential thunderstorm complex will be possible late
tonight to our northwest and then pushing into the area during the
day on Sunday. Still lots of uncertainty with this potential and
for now have generally kept pops on the lower side (15-40%). The
best potentiall would again be in the north and then the eastern
CWA. Temperatures and heat index values will be kept a bit lower
there on Sunday, but continued hot in the mid to upper 90s in the
southwest CWA. Will maintain a heat advisory on Sunday for the
southwest part of the CWA. The remainder of the CWA should be
below critiera and the heat headlines will be dropped there when
this evenings products expire.

.LONG TERM...(Sunday Night through Saturday)
Issued at 203 PM CDT Sat Jul 29 2023

The upper ridge will eventually build back to the east during the
week, which will keep the heat and humidity in place over the area
for much of the week. There will be some scattered thunderstorm
chances with the better chances in the eastern CWA which will be
on the edge of the ridge.

Temperatures will creep back up into the upper 90s to 103 through
the middle of next week in the west, while the east may hold back
in the upper 80s to mid 90s. Areas in the west will likely need
additional heat products through the week.

Heading into Thursday, the ridge axis will more or less be
overhead with 850mb temperatures from 25 to 31 degrees C. We
should see temperatures rise back into the upper 90s to 104 across
the area with heat index values from 105 to 110 on Thursday.

Models do show a front moving through on Friday which should bring
temperatures down to more normal readings for Friday and Saturday.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1147 AM CDT Sat Jul 29 2023

For the 18z TAFS, two main areas of convection. The first was just
east of BBG but should not affect that site as this activity
shifts east this afternoon. The second is with an ongoing
thunderstorm complex in central and northern Missouri. While the
main activity with this complex will stay north of the forecast
area, the outflow may regenerate some convection within the
unstable air mass south of the main complex this afternoon and
evening. We will keep some convection chances at SGF/BBG for the
mid afternoon through early evening to account for this. Generally
expecting VFR conditions, but could see some MVFR and brief IFR
within any convection that may develop.
