.MESOSCALE...
Issued at 837 PM CDT Tue Jun 25 2024

00z KSGF sounding measured a very moist and unstable airmass
with 4000j/kg of MU CAPE, 0 CIN and PW values of 1.80in. A
cluster of thunderstorms has continued to affect the Rolla/Vichy
area with a general southerly direction. This activity will
continue dropping south and affect areas along and east of the
Highway 63 corridor through 11pm. Overall the severe threat is
low with this activity. A lone storm has continued to move east
along the KS/OK border and may try to move into southeast
Kansas. Slightly higher shear out there could allow for it to
remain severe and will monitor that storm for the next few
hours.

Of greater concern for the overnight hours is the development of
severe storms currently across Nebraska and Iowa. These storms
are developing along a frontal boundary within a higher sheared
environment. Latest 00z HRRR and last few WOFS runs indicate
that these storms will continue to merge/conglomerate and
develop cold pools as they move south, following propagation
vectors. Therefore, expect at least a few clusters of storms or
line segments to move towards the KC metro and then into our
area generally late, after midnight. There also appears to be a
weak low level jet that develops across Kansas and Oklahoma with
some development of storms likely in a north to south corridor
on the edge of this jet. This could occur closer to the
Missouri/Kansas border area ahead of the incoming storms. Given
the high instability and weak inhibition storms just need a
trigger and other isolated storms could develop across the rest
of the CWA before the main batch of storms arrives late.

That main batch of storms look to arrive along the I-44
corridor between 3am-7am and continue to move southeast from
there in the morning. Given the amount of instability and
moisture, damaging winds of 60-70 mph is the most likely hazard.
Frequent lightning will also be a concern. The flooding threat
looks to be limited given the progressive nature of the storms
and the dry conditions lately however any areas that see slower
moving or repeated storms could see localized flooding. Those
outdoors tonight will need to remain weather aware given the
damaging wind potential.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 253 AM CDT Wed Jun 26 2024

A line of thunderstorms is currently moving SSE across northern
Missouri producing 60+ mph wind gusts and small hail. This line is
expected to stay on its current trajectory and may even accelerate,
prompting a newly issued Severe Thunderstorm Watch for much of the
area (mainly east of Springfield) until 900 a.m. CDT. Additionally,
discrete cells are beginning to initiate in eastern Kansas as a low-
level jet begins to nose into the KS/MO border. These have largely
remained sub-severe so far, but are in a favorable environment and
are starting to develop more impressive cores. These are also
moving SSE with additional development behind them into KS.
These may impact our farthest west counties before the main line
comes through and absorbs them.

A second line of storms is positioned a bit to the NW of the line in
northern Missouri, over the NE/KS border. This line is expected to
merge with the first, and the impact of this interaction is not well
anticipated. The whole system may briefly intensify before one line
becomes dominant. With MUCAPE of over 3000 and favorable orientation
of deep layer shear vectors, the atmosphere is primed for this
system to sweep through the area with notable force. Another watch
may be needed a bit later for the counties west of Springfield
initially left out of the current watch ahead of the westernmost
portion of the new mega-line. Wind gusts 60-70 mph are the primary
hazard tonight.

Rain will end from northwest to southeast through late morning and
midday. Clouds appear to clear out quickly behind the rain allowing
for highs to warm into the mid 80s (east) and low 90s (west). Heat
Index values will get into the low 90s (east) and low to mid 100s
(west). It will feel hottest in the far southwest corner of MO, but
values of 105 or greater should be sparse if present at all, so no
Heat Advisory needed today. Still, the heat may be oppressive
especially in the south and west, so continue to practice heat
safety today. Quiet night tonight with lows in the low to mid
70s.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 253 AM CDT Wed Jun 26 2024

Behind the cold front that is forcing our severe storms tonight,
temperatures will drop a bit for Thursday, with most seeing Heat
Index values in the upper 80s and those in the west and south seeing
values in the low 90s. Some transient shortwave energy may allow for
scattered showers across central Missouri Thursday into Friday
night, but the main system arrives Friday night through Saturday
night. Details on this activity are still coming through, but the
Storm Prediction Center has outlined the northern half of the area
in a Marginal (1/5) risk for severe thunderstorms Friday (Day 3).

We're still seeing heat through the weekend, but some relief can be
expected on Sunday behind this storm activity. High temperatures
look to be in the mid to upper 80s with Heat Index values largely
remaining under 90. Unfortunately, ridging appears to build back in
for the beginning of the work week, bringing oppressive heat once
again. Currently forecasted Heat Index values are pointing to more
Heat Advisories being needed, but we will have to see how this week-
out guidance changes as we get closer.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1223 AM CDT Wed Jun 26 2024

VFR conditions will generally prevail for most of the night,
however a line of thunderstorms will move through from the
northwest beginning around 10Z. This line will bring temporarily
reduced VIS/CIG around sunrise until late morning. Flight cats
may drop into IFR/LIFR if ceilings get low enough. Some moderate
LLWS is also expected as this line moves through. We will be
back to sunny skies by the end of the TAF period.
