DISCUSSION
ISSUED AT 350 PM CDT MON JUN 8 2026
VERY ACTIVE WEATHER PATTERN EXPECTED TO CONTINUE THIS WEEK. BROAD
LOW LEVEL WARM AIR ADVECTION EXISTS EAST OF SURFACE LOW ACROSS SOUTH
CENTRAL KS. FAIRLY WEAKLY CAPPED ENVIRONMENT ACROSS THE REGION THIS
AFTERNOON, AND COULD SEE AN ISOLATED STORM OR TWO THROUGH THE LATE
AFTERNOON/EARLY EVENING. STEEP LAPSE RATES IN THE 600-525 MB RANGE
AIDING IN DESTABILIZATION THIS AFTERNOON WITH ~2000 J/KG OF CAPE
ACROSS THE REGION. WHILE WIND SHEAR IS RELATIVELY WEAK AROUND 25
KNOTS, COULD POSSIBLY GET A BRIEF STRONG STORM THROUGH AMPLE SURFACE
HEATING LATE THIS AFTERNOON INTO THE EVENING HOURS, THOUGH THERE IS
NOT MUCH IN THE WAY OF A LOT OF UPPER LEVEL SUPPORT. STRATUS ACROSS
EASTERN KS INTO CENTRAL MO HAS LED TO
WEAK SHORT WAVE ACROSS NORTH CENTRAL KS AS OF 20Z IS EXPECTED TO
LEAD TO THE DEVELOPMENT OF SUPERCELLS ACROSS SOUTH CENTRAL NEBRASKA.
THESE STORMS COULD GROW UPSCALE INTO AN MCS AND BUILD SOUTHEAST
ALONG THE THERMAL RIDGE. HRRR AND RRFS HAVE BEEN BEEN FAIRLY
CONSISTENT WITH THIS IDEAL SINCE THE 12Z RUNS, WHILE THE
DETERMINISTIC RUNS HAVE REALLY STRUGGLED COMING UP WITH A CONSISTENT
SOLUTION. THE 18Z HRRR HAS SINCE PIVOTED TO DEVELOPING SUPERCELLS
ACROSS EASTERN KS THIS EVENING, AND BRINGS IN REMNANTS OF A COMPLEX
ON TUESDAY MORNING. THE LOW LEVEL JET IS INITIALLY FOCUSED ACROSS
OKLAHOMA, BUT BUILDS NORTH IN TIME ACROSS EASTERN KS INTO WESTERN MO
AFTER 06Z TUESDAY. 18Z SOUNDING FROM TOP IS MOIST WITH 1.7" OF
PRECIPITABLE WATER, AND WARM CLOUD DEPTHS ARE IN THE 13-14K FOOT
RANGE. POINT IS, THERE IS A QUITE A BIT OF UNCERTAINTY ON HOW
THINGS MIGHT EVOLVE TONIGHT, BUT POTENTIAL FOR DAMAGING WINDS, HAIL,
AND HEAVY RAINFALL EXISTS.
THIS UNCERTAINTY CONTINUES INTO TUESDAY WITH THE POTENTIAL FOR LOW
CLOUDS AND LINGERING STORMS TRANSITIONING TO VERY WARM AND MUGGY
CONDITIONS AS UPPER LEVEL RIDGE . DEPENDING ON HOW QUICKLY CLOUDS
CLEAR THROUGH THE DAY, SURFACE TEMPERATURES ARE EXPECTED TO WARM
INTO THE UPPER 80S AND POTENTIALLY LOWER 90S F. WITH DEW POINTS WELL
INTO THE 70S, HEAT INDICES ARE EXPECTED TO WARM INTO THE UPPER 90S
TO LOWER 100 F. TRIED TO CONCENTRATE THE HEAT ADVISORY IN AREAS
THAT SHOULD SEE CLEARING EARLIER IN THE DAY ALLOWING FOR BETTER
INSOLATION.
AIR YOU CAN WEAR CONTINUES INTO WEDNESDAY AHEAD OF A COLD FRONT
APPROACHING FROM THE NORTHWEST. WITH INCREASING CONFIDENCE, THERE
MAY BE A NEED FOR HEAT HEADLINES, ESPECIALLY WITH MOISTURE POOLING
AHEAD OF THE APPROACHING FRONT. MODELS HAVE BEEN INCONSISTENT IN THE
TIMING OF THE FRONT, BUT COULD SEE ADDITIONAL STORMS WITH THE FRONT
AND ARE OUTLOOKED FOR SEVERE POTENTIAL WEDNESDAY INTO THURSDAY.
ADDITIONAL STORMS ARE POSSIBLE ON SATURDAY INTO SATURDAY NIGHT AS
SHORTWAVE DROPS INTO THE NORTHERN PLAINS THIS WEEKEND, WITH A
POTENTIAL DEEPENING SURFACE REFLECTION. AS CAN BE EXPECTED AND WITH
MODELS NOT HANDLING THE NEAR TERM WELL, THERE IS A WIDE VARIETY OF
SOLUTIONS FOR THE WEEKEND.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1218 PM CDT MON JUN 8 2026
ACTIVE WEATHER IS EXPECTED ACROSS THE REGION FOR MUCH OF THE TAF
PERIOD. THIS AFTERNOON/EARLY EVENING, ISOLATED SHOWER/STORM
DEVELOPMENT COULD IMPACT AREAS IN EASTERN KANSAS AND WESTERN
MISSOURI. HOWEVER, CONFIDENCE IN DEVELOPMENT IN THESE AREAS IS
LIMITED, THUS HAVE OPTED FOR A BRIEF PROB30 FOR -TSRA BETWEEN
22Z AND 01Z IN THE CORRIDOR OF TERMINALS. ISOLATED/SCATTERED
DEVELOPMENT IS MORE LIKELY IN NORTHERN/EASTERN MISSOURI DURING
THIS TIME PERIOD, BUT A ROGUE SHOWER/STORM CANNOT BE RULED OUT
ALONG THE MISSOURI/KANSAS BORDER. AFTER DARK TONIGHT, AN MCS IS
EXPECTED TO ROLL THROUGH KANSAS AND POTENTIALLY INTO THE
CORRIDOR OF TERMINALS. CONFIDENCE IN TIMING, INTENSITY, AND
EASTWARD EXTENT REMAINS LOW, HENCE AN ADDITIONAL PROB30 FOR TSRA
BETWEEN 04Z AND 08Z BEING INCLUDED. THE MCS, OR ANY REMNANTS, IS
EXPECTED TO HAVE MOVED INTO CENTRAL MISSOURI BY 12Z. BEYOND TSRA
POTENTIAL, EXPECT MVFR CIGS FOR MUCH OF THE TAF PERIOD WITH
SOUTHERLY SURFACE WINDS.
