.SHORT TERM /THROUGH THURSDAY NIGHT/...
Issued at 131 PM CDT Wed Apr 15 2026

Synoptic overview and current conditions: Water vapor imagery
and upper level analysis show deep southwesterly flow aloft from
west Texas into New England. Upper low was located over Nebraska
with a trough extending southwest of the low into New Mexico
with another low entering the Pacific northwest. Surface front
was shifting out of central KS into eastern KS where surface
based CAPES were in the 3500-4000 j/kg and no CIN was residing.
The morning convection and low clouds have kept some CIN values
around 50-100 j/kg in the eastern half of the CWA, but this was
slowly eroding and better CAPES were spreading east into the
area. 0-6km shear values were around 50kts out of the southwest.
Still getting some scattered showers/storms over our eastern CWA
with the remnants of this mornings activity.

Severe weather this afternoon / tonight: Expecting convection to
develop along/ahead of cold front/dryline in eastern KS/OK
within the band of higher instability. This activity is expected
to initiaite slightly west of the CWA with some discrete
supercells possible which would include all modes of severe
storms. As the upper wave and surface front shift east by late
afternoon and early evening, storms may form into clusters or
qlcs segments. Damaging wind and an embedded tornado risk will
be the main severe weather risks this evening as the qlcs shifts
east. While there is some timing differences in the CAMS, the
main area of convection should exit the eastern CWA between
midnight and 3 am.

Thursday/Thursday night: Instability is expected to increase
during the afternoon in the wake of any residual precipitation
from the today/tonights shortwave. A secondary shortwave is then
expected to move through the area during the afternoon and early
evening with some of the CAMS generating additional convection
over the eastern Ozarks. We are currently in a marginal risk(1
of 5) for this activity, in which the main risk would be with
large hail. Anything that develops should move out of the area
by the early evening.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
Issued at 131 PM CDT Wed Apr 15 2026

Severe weather chances late Friday into Saturday morning: The
upper level wave currently entering the Pacific northwest will
continue to track east and into the plains during the day on
Friday. A strong upper level jet out of the southwest will be
southeast of the trough and move into the area late in the day.
strong southerly winds in the lower levels will advect Gulf
moisture into the area during the day. With temperatures and
moisture increasing in the low levels, instability will increase
ahead of an eastward moving dry line/cold front which will begin
to push into the area during the late afternoon or early
evening. Discrete supercells are expected to develop ahead of a
dryline over the central/southern plains and dryline. As the
upper wave shifts eastward, the cold front will overtake the
dryline and storms should begin to form into a qlcs with
damaging wind and spin-up tornado risks becoming the more
predominant severe weather risks. The storms and front will
continue to track east across the CWA during the night and
potentially into Saturday morning before ending. This upper wave
will finally end our persistent pattern of southwest flow aloft
with drier air moving in behind the wave and surface front for
the remainder of the weekend into early next week.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1209 PM CDT Wed Apr 15 2026

For the 18z TAFS, surface based CAPES starting to increase to
our west and should creep in here throughout the afternoon.
Could see storm initiation ahead of a dryline towards the onset
of the 18z TAFS to the west of the CWA, however some scattered
activity will be possible over the area before that main area
moves in. Have gone with prob30s until late afternoon and then a
predominant TSRA with heavier rain between 23z and 02z as the
main line moves through. Expecting MVFR conditions with brief
periods of IFR within the stronger convection. Things should
clear east of the TAF sites by 03-04z. May get some stratus in
here overnight towards morning, especially at the BBG site.
