DISCUSSION
(THIS AFTERNOON THROUGH SATURDAY)
ISSUED AT 1252 PM CDT SUN APR 26 2026
NOT MUCH HAS CHANGED IN THE OVERALL THINKING WITH THE FORECAST
FOR THE NEXT FEW DAYS. ISOLATED CHANCES FOR A THUNDERSTORM REMAIN
IN THE FORECAST FOR OUR SW TODAY, WITH MOST OF THE REGION STAYING
DRY THOUGH MONDAY AFTERNOON DUE TO SURFACE RIDGING OFF TO THE
EAST. MORE ORGANIZED RAIN CHANCES RETURN TO THE FORECAST MONDAY
NIGHT, AS A DECAYING LINE OF STORM TO SEVERE STORMS BEGINS TO
WORK INTO THE REGION FROM THE NW.
THE STORM PREDICTION CENTER (SPC) HAS MAINTAINED THE MARGINAL
RISK (LEVEL 1 OF 5) FOR MONDAY NIGHT, AS A WEAK SHORTWAVE IS
EXPECTED TO MOVE OUT AHEAD OF THE COLD FRONT DRAPED FROM THE
MIDWEST, BACK DOWN TO THE SOUTHERN PLAINS. AN ORGANIZED COMPLEX
OF THUNDERSTORMS WILL GENERALLY DROP SE ALONG THIS COLD FRONT AND
SHORTWAVE, GRADUALLY LOSING STEAM AS IT MOVES FARTHER AWAY FROM
THE BEST FORCING. AT THIS TIME, IT LOOKS LIKE THIS COMPLEX COULD
MOVE INTO THE REGION BETWEEN 3-5 AM ON TUESDAY. IN THE EVENT IT'S
ABLE TO MAINTAIN ITS STRUCTURE, DAMAGING WINDS WILL BE THE MAIN
SEVERE WEATHER THREAT. HOWEVER, I HAVE SERIOUS RESERVATIONS ABOUT
THAT BEING THE CASE AT THE TIME OF THIS DISCUSSION. THE COMPLEX
QUICKLY MOVES AWAY FROM THE BEST FORCING, AND THE BETTER AXIS OF
INSTABILITY IS REALLY LIMITED. IN THE EVENT THESE VALUES ARE EVEN
LOWER THAN FORECAST, THE SEVERE WEATHER THREAT MAY NOT EVEN
MATERIALIZE. REGARDLESS IF THAT HAPPENS OR NOT, THUNDERSTORMS ARE
EXPECTED TUESDAY MORNING, AND EXPECTED TO LINGER INTO TUESDAY
AFTERNOON.
THE SPC HAS ALSO MAINTAINED THE SLIGHT RISK (LEVEL 2 OF 5) FOR
TUESDAY NIGHT, AS ADDITIONAL SEVERE STORM DEVELOPMENT IS EXPECTED
ALONG THE COLD FRONT TO OUR WEST. AS TIME GOES ON, THESE STORMS
WILL GO UPSCALE, BEFORE WORKING INTO OUR REGION AS ANOTHER
ORGANIZED COMPLEX. MUCH LIKE TONIGHT, THE BETTER AXIS OF
INSTABILITY SEEMS TO BE TO OUR NW, WITH VALUES QUICKLY DECREASING
ONCE THE SUN SETS. HOWEVER, INSTABILITY VALUES ARE NOT
INSIGNIFICANT, AND THE FORCING SHOULD BE BETTER TUESDAY NIGHT AS
WELL. THE MAIN THREAT WILL BE DAMAGING WINDS, BUT LOW CHANCES
ALSO EXIST FOR AN ISOLATED TORNADO.
SHOWER AND THUNDERSTORM CHANCES WILL LINGER ACROSS THE REGION FOR
THE REST OF THE DAY ON WEDNESDAY, BEFORE THE STALLED COLD FRONT
MOVES THROUGH WEDNESDAY NIGHT. FROM HERE, DRY CONDITIONS RETURN
TO THE FORECAST, WITH COOLER TEMPERATURES EXPECTED INTO THE
WEEKEND AS WELL. HOWEVER, RAIN CHANCES WILL RETURN TO THE
FORECAST BY NEXT WEEKEND, AS THE NEXT ORGANIZED SYSTEM IS
EXPECTED TO WORK THE REGION THEN.

AVIATION
(00Z TAFS)
ISSUED AT 643 PM CDT SUN APR 26 2026
NORTHERLY FLOW HAS BROUGHT DRIER AIR TO THE STATE WITH VFR
CONDITIONS EXPECTED THROUGH THE TAF PERIOD. A MID LEVEL JET WILL
MOVE ACROSS THE STATE TOMORROW BRINGING GUSTING WINDS TO EACH TAF
SITE. THERE IS A LOW CHANCE FOR CONVECTION, WITH HIGHER CHANCES
ACROSS THE NORTHWEST OF THE STATE. BECAUSE OF THE PROXIMITY AWAY
FROM ANY TAF SITE, HAVE NO MENTION OF VICINITY SHOWERS OR THUNDER
THROUGH MONDAY.
AMD NOT SKED AT KTCL DUE TO INTERMITTENT COMMS ISSUES.
NOTE: SPRING SEASONAL ISSUANCE OF THE TAF FOR KASN IS NOW BEING ISSUED
AND WILL RUN THROUGH 04/29 18Z.

FIRE WEATHER
DUE TO INCREASING MOISTURE AND RAIN CHANCES INTO MONDAY,
CONFIDENCE IS MEDIUM IN MINRH VALUES REMAINING ABOVE 50% THROUGH
WEDNESDAY. MINRH VALUES WILL DROP AGAIN ON THURSDAY BEHIND A
PASSING COLD FRONT, BEFORE INCREASING ONCE MORE BY NEXT WEEKEND.
THANKFULLY, ORGANIZED RAIN CHANCES WILL REMAIN IN THE FORECAST
THROUGH THURSDAY AS WELL, BEFORE DRYING OUT INTO THE WEEKEND.
EVEN WITH ONGOING RAIN CHANCES, FIRE WEATHER CONCERNS WILL REMAIN
ELEVATED DUE TO THE WIDESPREAD DROUGHT CONDITIONS AND CRITICALLY
DRY FUELS.
