DISCUSSION
ISSUED AT 205 PM CDT SUN AUG 9 2026
EARLY THIS AFTERNOON, A CUMULUS FIELD REMAINS FOCUSED NORTH OF THE
AREA ALONG A THETA‑E AND INSTABILITY GRADIENT OVER SOUTHEASTERN
NEBRASKA, WITH ONLY A LOW PROBABILITY THAT ANY ACTIVITY BRUSHES FAR
NORTHEAST KANSAS AS IT MOVES EAST‑SOUTHEAST WITH THE MEAN FLOW. A
CAPPED BOUNDARY LAYER AND GENERALLY WEAK LARGE‑SCALE ASCENT CONTINUE
TO LIMIT CONVECTIVE INITIATION OVER MOST OF THE AREA, THOUGH A
STRENGTHENING LOW‑LEVEL JET AND STEEP MID‑LEVEL LAPSE RATES TONIGHT
MAY ALLOW ISOLATED ELEVATED THUNDERSTORMS IF PARCELS CAN OVERCOME
LINGERING CIN. GIVEN MODEST SHEAR AND INSTABILITY, ANY STORMS THAT DO
FORM COULD BRIEFLY PRODUCE STRONG, POSSIBLY DAMAGING WINDS, BUT THE
OVERALL SEVERE THREAT IS CONSTRAINED BY THE EXPECTED SPARSE COVERAGE
AND CAPPING.
THE MAIN STORY THEN SHIFTS TO HEAT AS H85 TEMPERATURES WARM TOWARD 30
°C BENEATH AN EXPANDING SUBTROPICAL RIDGE ALOFT, SUPPORTING
AFTERNOON HIGHS IN THE UPPER 90S TO AROUND 100 ACROSS CENTRAL AND
NORTHEAST KANSAS THROUGH AT LEAST WEDNESDAY. TOMORROW’S HEAT MAY BE
MILDLY MITIGATED BY SOME HIGH LEVEL CLOUDS, BUT GENERALLY, HEAT
INDICES AROUND 100–105 DEGREE RANGE CONTINUE TO LOOK POSSIBLE THROUGH
WEDNESDAY THANKS TO PERSISTENT MOIST SOUTHERLY FLOW AND AN UPPER-
LEVEL RIDGE NEARBY.
BY MIDWEEK, GUIDANCE INDICATES THE RIDGE BEGINS TO FLATTEN AS A
FRONTAL ZONE DROPS INTO THE CENTRAL PLAINS, LEADING TO GRADUALLY
INCREASING POPS FROM WEDNESDAY NIGHT ONWARD. WITH INCREASING CHANCES
FOR PRECIPITATION AND A FURTHER SOUTH FRONTAL ZONE, SOMEWHAT COOLER
HIGHS IN THE MID 80S TO LOWER 90S ARE MORE LIKELY.
AVIATION /06Z TAFS THROUGH 06Z TUESDAY/
ISSUED AT 1222 AM CDT MON AUG 10 2026
WINDS CONTINUE FROM THE SOUTH TO SOUTHWEST OVER THE NEXT
24 HOURS AT AROUND 10 KTS. WITH A STRONG SOUTHWESTERLY LLJ, MARGINAL
LLWS WILL CONTINUE UNTIL A BIT AFTER SUNRISE. VFR CONDITIONS WILL
PERSIST THROUGH THE PERIOD, WITH BEST CHANCE OF ANY SHOWERS/STORMS
NORTH OF THE MAIN TERMINALS. CAN'T RULE OUT SOME VIRGA DURING THE
DAY THOUGH AS MID/HIGH CLOUDS THICKEN AND HIGH-BASED SHOWERS
EVAPORATE INTO THE DRY AIR BELOW.
TOP WATCHES/WARNINGS/ADVISORIES
NONE.
