DISCUSSION
ISSUED AT 1207 PM CDT THU JUL 2 2026
A FEW STORMS FINALLY MANAGED TO BREAK THROUGH THE CAP DURING THE
EARLY MORNING HOURS TODAY, DROPPING A FEW SWATHS OF HAIL, GUSTY
WINDS, AND HEAVY RAIN ACROSS PORTIONS OF NORTHEAST NEBRASKA. CLOUD
COVER AND SPOTTY SHOWERS HELPED KEEP TEMPERATURE RELATIVELY COOL,
SIMILAR TO YESTERDAY. BY NOON, TEMPERATURES HAD REACHED THE **UPPER
70S AND LOW 80S. DEWPOINTS IN THE LOW 70S BROUGHT HEAT INDICES INTO
THE UPPER 80S AND LOW 90S.
A REMNANT MCV ROLLED THROUGH EASTERN NEBRASKA OUT OF KANSAS THIS
MORNING. WHILE THE ATMOSPHERE WAS STILL A LITTLE TOO WORKED OVER
FROM MORNING CONVECTION, A FEW CAMS HINT AT THE POTENTIAL FOR STORMS
TO REDEVELOP LATE THIS AFTERNOON ALONG A LINGERING OUTFLOW BOUNDARY
IN FAR SOUTHEAST NEBRASKA. WHILE SHEAR WILL BE RELATIVELY WEAK,
BOUNTIFUL INSTABILITY COULD LEAD TO THE PRODUCTION OF LARGE HAIL AND
DAMAGING WINDS.
A BETTER CHANCE FOR STRONG TO SEVERE STORMS WILL MOVE THROUGH LATE
THIS EVENING AND INTO THE OVERNIGHT HOURS. MULTIPLE MODELS HINT AT
THE DEVELOPMENT OF AN MCS OVER EASTERN SOUTH DAKOTA THAT MOVES
SOUTHEAST ACROSS FAR EASTERN NEBRASKA AND WESTERN IOWA TONIGHT. THIS
INITIAL STORM MAY THEN BE FOLLOWED BY AN AMALGAMATION OF CELLS
MOVING OUT OF CENTRAL NEBRASKA. THE INITIAL STORMS THAT DEVELOP THIS
EVENING WOULD BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WINDS,
WITH A SMALL CHANCE FOR A TORNADO OR TWO. HEAVY RAIN COULD ALSO LEAD
TO ISOLATED INSTANCES OF FLOODING IF STORMS END UP TRAINING OVER THE
SAME LOCATIONS.
FRIDAY...
ONCE AGAIN, CONVECTION IS EXPECTED TO LINGER THROUGH THE MORNING
HOURS FRIDAY, BRINGING SUBTLE RELIEF FROM THE HEAT. TEMPERATURES
WILL LIKELY ONCE AGAIN TOP OUT IN THE UPPER 80S AND LOW 90S FRIDAY
AFTERNOON. ADDING IN THE HUMIDITY, IT WILL FEEL MORE LIKE THE MID
90S TO LOW 100S.
WHILE THE FORECAST MAY ONCE AGAIN BECOME MUDDLED BY STORM
INTERACTIONS THURSDAY NIGHT/FRIDAY MORNING, MACHINE LEARNING AND CAM
GUIDANCE STRONGLY SUPPORT ADDITIONAL STORM DEVELOPMENT FRIDAY
EVENING. CONVECTION LOOKS TO BLOSSOM ALONG ANOTHER OUTFLOW BOUNDARY
IN THE VICINITY OF NORTHEAST NEBRASKA. LARGE HAIL, HEAVY RAIN, AND
PERHAPS A TORNADO OR TWO WILL ALL BE POSSIBLE. HOWEVER, THE GREATEST
THREAT LOOKS TO BE STRONG DAMAGING WINDS AS THE STORMS EVENTUALLY
MELD TOGETHER INTO AN MCS AND SURGE SOUTHEAST THROUGH EARLY SATURDAY
MORNING.
SATURDAY (INDEPENDENCE DAY)...
FRIDAY NIGHT CONVECTION WILL BE THE DECIDING FACTOR IN WHETHER OR
NOT WE CAN SHOOT OFF OUR OWN FIREWORKS ON SATURDAY, OR IF WE'LL BE
FORCED TO WATCH MOTHER NATURE'S SHOW. SOME MODELS DEPICT STORMS
SURGING WELL SOUTH OF THE FORECAST AREA FRIDAY NIGHT/SATURDAY
MORNING, CLEARING THE PATH FOR A HOT BUT DRY 4TH. OTHER SOLUTIONS
DEPICT FRIDAY NIGHT'S STORMS GIVING US A GLANCING BLOW AS THEY SKIRT
ALONG THE EASTERN FRINGES OF THE FORECAST AREA. THIS WOULD LEAVE US
UNDER AN UNSPOILED ATMOSPHERE RIPE FOR THUNDERSTORM DEVELOPMENT
SATURDAY AFTERNOON AND EVENING. OVERALL TRENDS APPEAR TO BE LEANING
TOWARD THE FIRST OPTION, PUSHING STORMS JUST SOUTH OF THE FORECAST
AREA. WHILE I WOULDN'T CANCEL FIREWORKS PLANS JUST YET, IT WOULD BE
A GOOD IDEA TO KEEP AN EYE ON THE FORECAST IF YOU HAVE HOLIDAY
PLANS.
HYDRATION (WITH WATER) WILL BE KEY FOR ANY 4TH OF JULY PARTY GOERS.
TEMPERATURES WILL REMAIN IN THE UPPER 80S AND LOW 90S, WITH HEAT
INDICES IN THE UPPER 90S UP TO 100. THESE TEMPERATURES COULD CREEP
UP A LITTLE HIGHER IF SKIES CLEAR OUT BEHIND THE EARLY MORNING
STORMS.
SUNDAY AND BEYOND...
OFF AND ON STORM CHANCES LOOK TO CONTINUE THROUGH SUNDAY AND INTO
EARLY NEXT WEEK. UNFORTUNATELY, THE HEAT ALSO ISN'T ENDING ANY TIME
SOON. AFTERNOON HIGHS ARE EXPECTED TO REMAIN IN THE UPPER 80S TO LOW
90S, WITH LOWS ONLY FALLING TO THE UPPER 60S AND LOW 70S OVERNIGHT.
ADDITIONALLY, CPC OUTLOOKS CONTINUE TO HIGHLIGHT MUCH OF THE COUNTRY
LEANING ABOVE NORMAL FOR TEMPERATURES THROUGH MID-JULY.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 1214 AM CDT FRI JUL 3 2026
STRONG TO SEVERE T-STORMS HAVE DEVELOPED JUST NORTH OF KOFK
TONIGHT AND ARE EXPECTED TO BACK-BUILD OVER THE AERODROME THROUGH
ABOUT 3AM. THEY'LL FINALLY MOVE OFF TO THE EAST AND LEAVE THE
AREA DRY AFTER THAT. EXPECT OMA AND LNK TO REMAIN DRY, BUT
STORM DEVELOPMENT HAS BEEN HARD TO PIN DOWN ALL DAY AND
CONFIDENCE IS LOWER THAN NORMAL.
AFTER STORMS QUIET DOWN, PARTLY CLOUDY SKIES ARE FORECAST FOR
THE MAJORITY OF FRIDAY BEFORE MORE THUNDERSTORM DEVELOPMENT ON
FRIDAY EVENING. AGAIN, TIMING IS QUESTIONABLE, BUT CURRENT
THINKING IS MORE STORM INITIATION AROUND THE 10PM TIME PERIOD.
LOTS OF UNCERTAINTY IN PLACEMENT AND TIMING REMAINS THIS FAR
OUT. HAVE ADDED THEM TO KOMA AND KLNK, BUT KOFK COULD EASILY
SEE SOME STORMS FRIDAY NIGHT AS WELL.
