What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Wichita, KS wrote its last area forecast discussion before this red flag warning went out at Apr 12, 12:40 PM CDT, 53 minutes earlier. Its key messages:

  • Showers and thunderstorms will linger over southeast Kansas this morning. Severe weather is not expected.
  • A severe thunderstorm or two may be possible late this afternoon into the early evening hours and again on Monday late afternoon into the evening hours with an isolated storm along the dryline.
  • Better chances for severe thunderstorms and associated severe may arrive on Tuesday, possibly lingering into Wednesday.
  • Additional thunderstorm chances possible next Friday- Saturday.

.KEY MESSAGES...

- Showers and thunderstorms will linger over southeast Kansas this
  morning. Severe weather is not expected.

- A severe thunderstorm or two may be possible late this
  afternoon into the early evening hours and again on Monday
  late afternoon into the evening hours with an isolated storm

.DISCUSSION...
Issued at 250 AM CDT Sun Apr 12 2026

Ongoing showers and thunderstorms developing over central and
northern OK will lift into parts of south central and much of
southeast Kansas late tonight while lingering over southeast Kansas
through the mid/late morning hours. This activity was associated
with a subtle shortwave trough lifting out of the Southern Plains.
Some subtle afternoon height rises/subsidence in the wake of this
trough will likely preclude deep moist convection this afternoon for
much of the area. There is a nonzero chance for a rogue storm or two
to develop along the dryline late this afternoon/early evening as
the low level winds back toward 00Z and the airmass is progged to
remain only weakly capped. Steep mid-lvl lapse rates/ML CAPE over
1500 J/KG and veering winds with height/deep layer shear around
35 knots would support some storm organization with large
hail/damaging winds assuming a storm can develop.

The dryline is progged to mix further eastward as we move into Monday
with deep vertical mixing/strong winds impacting locations in the
wake of the dryline. Deep vertical mixing will result in very dry
conditions and gusty winds with extreme fire danger anticipated for
parts of central and western Kansas. Once again, we could see an
isolated afternoon/evening storm or two develop along the
dryline late Monday as the cap weakens. If an isolated storm can
develop, steep mid-level lapse rates/MLCAPE over 2000 J/KG and
deep layer shear around 50 knots will support supercells with
all modes of severe weather possible. The window of opportunity
appears to be relatively brief along the Turnpike corridor
before the cap returns during the evening hours.

Tuesday...a mid/upper trough is progged to emerge from the Southern
Rockies late in the period. Very strong winds are progged through
the column with 0-6km bulk shear progged around 60-70 kt. Given the
magnitude of large-scale forcing for ascent, an earlier initiation
seems possible as the cap weakens around midday or possibly even
sooner. Early convection could impact the magnitude of severe
weather as we move into the afternoon hours. However, if the cap can
hold a bit longer, then we could be looking at more supercell storms
with all modes of severe weather during the afternoon/evening hours.

The threat for severe weather may begin to move east of the forecast
area as we move into Wed but there is still some uncertainty in the
progression of the mid/upper trough and some pops were maintained in
southeast KS to account for that uncertainty. Seasonably mild air is
expected in the wake of the system with highs mostly in the 70s on
Wed.

Breezy southerly winds and above normal temperatures will return to
the area on Thursday as a mid/upper ridge translates eastward across
the central CONUS. Meanwhile, the next vigorous mid/upper trough is
progged to build into the Central Great Basin area. This mid/upper
trough will move eastward into the Central and Northern Rockies on
Friday. Another round of severe storms appears possible with
activity along an advancing cold front, as well as storms developing
along a dryline. The warm sector is progged to be moist and unstable
while deep layer shear around 50 knots returns. This will bring the
potential for organized storms and severe weather once again late
Friday and Friday night.

A stable post-frontal regime will overspread the area on Saturday as
sfc high pressure settles over the area. Radiational cooling early on
Sunday could result in some frost as temperatures fall into the mid
and upper 30s. Seasonable temperatures will return in the wake of
the cold front with highs on Sunday in the mid 60s.

&&

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1237 PM CDT Sun Apr 12 2026

Low clouds and rain showers will gradually shift east of
southeast Kansas this afternoon. Meanwhile gusty south winds and
VFR conditions will prevail across the region for this afternoon
across central/south central Kansas with clearing skies. Low
level wind shear will develop over central/south central Kansas
by late evening and persist through the night time hours. Low
clouds will redevelop over southeast Kansas overnight as richer
low level moisture streams northward.

&&

.FIRE WEATHER...
Issued at 250 AM CDT Sun Apr 12 2026

Extreme grassland fire danger is expected on Monday and possibly
again on Tuesday afternoon along and west of a dryline where
afternoon relative humidity may fall into the teens. Deep vertical
mixing will also bring the potential gusty southwest winds. The area
of concern will be mainly west of Highway 14 or along and west of a
line from Lincoln to Ellsworth to Kingman to Harper. Otherwise,
spring green-up and higher humidity values should keep grassfire
danger in check for most areas, especially areas southeast of the
Kansas Turnpike.

Breezy southerly winds will return on Thursday and Friday resulting
in a very high grassland fire danger for Russell and Barton counties
in central Kansas.

This hazardous weather outlook is for portions of Central Kansas,
South Central Kansas and Southeast Kansas.

.DAY ONE...This Afternoon and Tonight

An isolated thunderstorm or two can't be ruled out late this
afternoon and evening, mainly west of Interstate 135. If a storm is
able to develop, severe weather is possible.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Similar to Sunday, an isolated thunderstorm or two can't be ruled
out late Monday afternoon and evening. If a storm is able to
develop, severe weather is possible.

Scattered thunderstorms are possible Tuesday afternoon and evening,
and possibly again Wednesday afternoon and evening over southeast
Kansas. Strong to severe thunderstorms capable of all severe
hazards are possible both days. Stay tuned as we refine forecast
details in the coming days.

Another storm system will arrive on Friday bringing the potential
for another rounds of severe storms.

Extreme grassland fire danger is possible west of a line from
Lincoln to Lyons to Harper on Monday and Tuesday during the
afternoon hours, due to very low humidity and gusty southwest winds
behind a dryline.

Spotter activation is not anticipated this afternoon or tonight.
