.SHORT TERM /THROUGH SATURDAY/...
Issued at 102 PM CDT Fri May 15 2026

Water vapor imagery and upper level analysis show a fairly zonal
flow across much of the CONUS with strongest jet energy from the
Pacific northwest into the upper Great Lakes. Some embedded
upper energy associated with a subtropical jet streak was
located from the southern plains into the mid Mississippi valley
and was aiding in developing some scattered showers and a few
embedded thunderstorms over the area. There is some elevated
instability, however we have a very strong cap in place over the
region. At the surface, a warm front continues to track east
across the forecast area. Temperatures have crept into the low
80s where some breaks in the clouds have occurred but have held
in the mid to upper 70s over the western portions of the CWA.
Dew points have risen into the upper 50s to mid 60s.

Rest of the Afternoon into Saturday: Will continue with
scattered showers and a few embedded thunderstorms through the
afternoon. More robust convection will develop along a frontal
boundary to our north and west and increase in intensity as the
low level jet strengthens tonight. CAMS develop a thunderstorm
complex over northern MO and track it southeast late tonight
into our northern CWA. Energy from the southwestern upper
shortwave will also continue to track into the area late tonight
into Saturday. We`ve increased pops especially in the north on
Saturday especially in the morning to account for the remnant
MCS activity and any additional development during the day with
the shortwave energy. Most of the convection should exit the
area by 00z. We are expecting mainly general thunderstorms with
the main severe weather risk remaining to our north. Storms late
tonight into early Saturday morning in central MO may still pose
a wind risk up to 60 mph.

The clouds and rain chances will keep temperatures slightly
cooler and have dropped highs slightly from previous forecasts.

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 102 PM CDT Fri May 15 2026

We are generally expecting Saturday night and Sunday to be dry
over the area as the upper trough out west deepens and the
surface front remains to our north. Main convection should
develop to our west and north Sunday afternoon and evening,
possibly affecting our far western CWA late Sunday night with
some convection. Winds will become quite gusty Sunday into
Monday with ensemble probabilistic data showing nearly 100%
chance of winds gusting over 30 mph both days.

The western CWA will have the best chances of strong to severe
thunderstorms on Monday with the front setting up over southwest
KS into northwest MO during the day, but then shifting southeast
into the area Monday night and Tuesday which will bring the
severe risk over most of the area during the day Tuesday. PW
values increase on Monday and Tuesday to above the 90th
percentile in the 1.4" to 1.5" range. We are also expecting
storms to bring heavy rain with the potential of localized
flooding.

The main upper wave will not arrive until Wednesday night into
Thursday which should then push all rain chances to the south
and east of the area.

For temperatures, we will flirt with some record warmest lows
Sunday into Tuesday and also record highs Sunday into Monday
across the area. See climate section for the current records in
these categories.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 652 PM CDT Fri May 15 2026

Scattered to broken middle to high level clouds will move over
the region this evening and through the overnight hours. Showers
and scattered storms associated with the shortwave that is
producing the cloud cover will allow for rain potential into
Saturday morning. Coverage is expected to be limited with any
periods of showers or storms short in duration. However, during
any precipitation period, flight conditions will fall from VFR
to MVFR with impacts to visibility and lightning the main
concerns.

Winds out of the south will increase into the overnight hours
with gust up to 25 kts through the period with low level wind
shear of 40 to 50 kts this evening and continuing through the
night as a low level jet develops.

More shortwave energy and potential remnants from a thunderstorm
complex may push into the area Saturday morning, thus the
inclusion of prob30 groups.
