DISCUSSION
ISSUED AT 127 PM CDT MON JUN 8 2026
A WEAK FRONT HAS SETTLED INTO NORTHEAST NEBRASKA EARLY THIS
AFTERNOON. THIS FRONT WILL GRADUALLY WEAKEN WITH TIME.
TEMPERATURES WARM INTO THE 80S THIS AFTERNOON WITH PARTLY CLOUDY
SKIES FOR MOST. BACK TO THE WEST, A COMPLEX OF THUNDERSTORMS IS
BEGINNING TO DEVELOP ACROSS CENTRAL NEBRASKA. THIS COMPLEX IS
FORECAST TO GRADUALLY TURN INTO A MATURE BOWING MCS WITH TIME.
THIS ACTIVITY TRACKS SOUTHEAST, MAINLY INTO KANSAS, BUT THE
NORTHERN PORTION MAY CLIP AREAS NEAR THE KANSAS BORDER.
DAMAGING WINDS WOULD BE THE MAIN THREAT WITH THIS MCS.
ELSEWHERE, A FEW ISOLATED THUNDERSTORMS ARE POSSIBLE ALONG THE
RESIDUAL FRONT OR NORTH OF THE COMPLEX. A STRONG TO SEVERE
THUNDERSTORM REMAINS POSSIBLE WITH DAMAGING WINDS AND LARGE HAIL
THE MAIN CONCERNS. IT REMAINS MUGGY TONIGHT WITH TEMPERATURES
IN THE 70S.
THE SYSTEM THAT SPAWNED THE COMPLEX OF THUNDERSTORMS TODAY WILL
LEAVE SUBSIDENCE IN ITS WAKE. THIS IS ANTICIPATED TO KEEP THE
AREA DRY AND MOSTLY SUNNY THROUGHOUT THE AFTERNOON ON TUESDAY.
AT THE SAME TIME, MID-LEVEL RIDGING BUILDS ACROSS MUCH OF THE
PLAINS. TEMPERATURES INCREASE WELL INTO THE 90S TO NEAR 100 WITH
MUGGY DEWPOINTS INTO THE 70S. AS A RESULT, MOST THE AREA SEES
HEAT INDICES IN THE LOW TO MID 100S PROMPTING A HEAT ADVISORY.
SHOWERS AND THUNDERSTORMS REMAIN IN THE FORECAST, BUT CONFIDENCE
IN MUCH OF THIS REACHING THE AREA REMAINS UNCERTAIN. WHILE A
HEALTHY AMOUNT OF INSTABILITY WILL BE IN PLACE, SUBTLE HEIGHT
RISES AND BETTER FORCING REMAINS TO THE WEST. THE LATEST
FORECAST GUIDANCE DISSIPATES MOST THUNDERSTORMS AS THEY REACH
OUR FORECAST AREA. THAT SAID, IF THUNDERSTORMS DO REACH THE
AREA, SEVERE WEATHER WILL BE A CONCERN. DAMAGING WINDS AND LARGE
HAIL WOULD BE THE MAIN THREATS.
AS A TROUGH APPROACHES THE REGION ON WEDNESDAY, A COLD FRONT
WILL SINK INTO THE REGION. TEMPERATURES REMAIN HOT, BUT DO
DECREASE COMPARED TO TUESDAY. UNLIKE TUESDAY, MORE FORCING WILL
BE IN PLACE AND STRONG TO SEVERE THUNDERSTORMS ARE ANTICIPATED
BY AFTERNOON ACROSS THE AREA. THIS MAY END UP BEING THE DAY WITH
THE GREATEST THREAT FOR SEVERE WEATHER THIS WEEK. CONTINUE TO
MONITOR THE FORECAST FOR THE LATEST DETAILS.
TEMPERATURES COOL BACK INTO THE 80S TO CLOSE OUT THE WEEK AND
BEGIN THE WEEKEND. INITIALLY, WE WILL HAVE A LOWER CHANCE OF
SHOWERS AND THUNDERSTORMS BEHIND WEDNESDAY'S SYSTEM, BUT ANOTHER
TROUGH LOOKS TO TAKE SHAPE BY THE WEEKEND. INCREASING
THUNDERSTORM CHANCES AND SOME SEVERE WEATHER POTENTIAL MAY
MATERIALIZE. KEEP TABS ON THE FORECAST FOR YOUR WEEKEND PLANS.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1211 PM CDT MON JUN 8 2026
VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH THE TAF PERIOD. A
FRONT IS ENTERING THE REGION, BUT THIS IS NOT ANTICIPATED TO
HAVE MUCH IMPACT. THE FRONT WILL CAUSE OFK'S WINDS TO BECOME
WESTERLY AND THEN NORTHERLY AS IT STALLS TO THE EAST OF THE
TERMINAL BEFORE SOUTHEAST WINDS RETURN TONIGHT. ELSEWHERE,
LIGHT SOUTHEAST WINDS CONTINUE THROUGH THE PERIOD. A COMPLEX OF
THUNDERSTORMS IS BEGINNING TO FORM OVER WEST-CENTRAL NEBRASKA.
THIS IS FORECAST TO TRACK SOUTHEAST THROUGH THIS AFTERNOON AND
EVENING. CURRENT GUIDANCE HAS THE BULK OF THIS ACTIVITY
REMAINING SOUTH OF INTERSTATE 80. LNK MAY SEE SHOWERS OR A
ISOLATED THUNDERSTORM AS THE COMPLEX PASSES TO THE SOUTH, BUT
CONFIDENCE IS LOW ON THIS OUTCOME CURRENTLY. ISOLATED
THUNDERSTORMS MAY FORM ELSEWHERE ACROSS THE REGION THIS
AFTERNOON, BUT THE PROBABILITY OF THIS ACTIVITY IMPACTING A
TERMINAL IS LOW.
