.SHORT TERM /THROUGH TONIGHT/...
Issued at 225 AM CDT Sat Apr 25 2026

Synoptic overview and current conditions: Upper level analysis
continues to show a closed low over southern Saskatchewan with
an active belt of mid and upper level energy from California
into the plains and MS valley. At the surface, a frontal
boundary was located from southwest to northeast across southern
Missouri with areas along and south of the front starting to see
fog development. Temperatures across the area were in the mid
50s to around 60 with dew points in the mid 50s.

Rest of the overnight into Saturday Night: HREF probs are
showing probabilities of visibilities at or below a half mile in
the 30 to 60% range overnight along the MO/AR border. Have
decided to go with a dense fog advisory through 9 AM for these
counties with a near zero dew point depression and nearly calm
wind southeast of the front. The fog should dissipate by mid
morning. Instability will begin to increase over the central and
southern plains as moisture begins to stream northward into the
region. Our forecast area will be on the northeastern fringes
of the best instability. CAMS are showing supercells developing
by the late afternoon into the evening west and southwest of the
area. A few of these storms may make it into southwestern
portions of the forecast area by mid to late evening but
anything over our area is likely to diminish by the late evening
if storms remain more scattered. If they can form more into
clusters or a line, then the risk may be maintained longer into
the overnight hours with mainly a wind risk.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 225 AM CDT Sat Apr 25 2026

A surface low will begin to strengthen over the plains as an
upper level trough begins to eject out of the Rockies into the
plains late Sunday into Sunday night. Sufficient instability and
shear will exist especially over our western half of the
forecast area for strong to severe storms with large hail and
damaging wind being the main severe weather risks.

The main upper wave and surface front will push through on
Monday. There remains considerable timing differences with this
system which will determine where the best severe weather
chances will exist over the area. A slower moving system will
favor severe storms across most of the area while a quicker
system would favor severe storms over the eastern half of the
CWA. Ample shear and instability should exist for all modes of
severe storms to develop within the severe weather risk.

There will exist a localized chance of excessive rainfall in
locations that receive repeat heavy rain over the weekend into
Monday.

Drier weather should move in behind this system through the
middle of the week with rain chances potentially moving back
into the area by late in the week.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1207 PM CDT Sat Apr 25 2026

Confidence is high that the area will remain rain/storm free for
the afternoon and evening hours however there is a 30 percent
chance of a thunderstorm across the area after 9pm with the
highest chances at JLN. Some brief MVFR ceilings at BBG will
improve to VFR late this afternoon. Winds will remain out of the
southeast around 10kts with occasional higher gusts on Sunday.
Low level wind shear is possible tonight however magnitudes are
currently too low to include.
