THUNDERSTORMS ARE BEGINNING TO DEVELOP ACROSS SOUTHERN NE AS THE
MAIN SHORTWAVE TROUGH APPROACHES FROM THE HIGH PLAINS. AMPLE
MOISTURE ADVECTION NORTHWARD ON A 55 KT LLJ WILL FOSTERCONTINUE
TO DEVELOPADDITIONAL STORM DEVELOPMENT FOR THE NEXT FEW HOURS
ACROSS SOUTHERN AND EASTERN NE. AS TIME PROGRESSES, SUPERCELLS
WILL CONGEAL INTO AN MCS WHILE APPROACHING IOWA AND FAR NORTHERN
MO. LARGE HAIL IS THE PRIMARY THREAT NOW, BUT AS THE TRANSITION
TO AN MCS OCCURS, DAMAGING WINDS WILL ALSO BECOME A CONCERN.
THE HIGHEST THREAT IS EXPECTED TO REMAIN MOSTLY ACROSS CENTRAL
AND SOUTHERN IA, BUT THE SOUTHERN END OF THE LINE APPEARS LIKELY
TO GRAZE FAR NORTHERN MO. SOME SUPERCELLULAR CHARACTERISTICS
MAY PREVAIL IN THIS SECTION OF THE LINE WITH THE LARGE HAIL
THREAT CONTINUING INTO THE MID MORNING HOURS. DEPENDING HOW FAR
SOUTH THE LINE REACHES WILL DETERMINE WHETHER THE ONGOING
FLOODING ACROSS NORTHERN MO IS EXACERBATED. THE FLOOD WATCH WAS
CANCELLED WITH THE THOUGHT THE HARDEST HIT AREAS WILL BE MISSED
FROM THIS MORNING'S ACTIVITY. THE MCS WILL CONTINUE TRACKING
EAST TO NORTHERN IL BY EARLY AFTERNOON.
THE LOW PRESSURE CENTER WILL BE LOCATED OVER CENTRAL/EASTERN IA
MIDDAY WITH A COLD FRONT EXTENDING SOUTHWEST INTO FAR NORTHWEST
MO AND EASTERN KS. ADDITIONAL THUNDERSTORM DEVELOPMENT WILL TAKE
PLACE ALONG THE FRONT MID AFTERNOON, LIKELY STRETCHING FROM WEST
CENTRAL TO NORTHEAST MO. NORTHWESTERN MO AND NORTHEAST KS MAY
BE SKIPPED BY THE SECOND ROUND. THE EXTENSIVE SQUALL LINE WILL
BE CAPABLE OF ALL SEVERE WEATHER HAZARDS. SOME SLIGHTLY BACKED
LOW LEVEL FLOW TOWARD NORTHEAST MO MAY AID WITH A BETTER TORNADO
THREAT THERE, OTHERWISE LARGE HAIL AND DAMAGING WINDS WILL BE
THE PRIMARY HAZARDS THROUGH LATE AFTERNOON.
THE FRONT WILL CLEAR TO THE SOUTHEAST BY EARLY EVENING AND THE
THUNDERSTORM RISK WILL END. MUCH COOLER AND DRIER AIR ARRIVES
WITH THE FRONTAL PASSAGE AND LOWS TONIGHT WILL DROP INTO THE
50S. CLEAR SKIES AND PLEASANT CONDITIONS FOR FRIDAY.
LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/
ISSUED AT 349 AM CDT THU JUN 11 2026
HIGH PRESSURE WILL SLIDE EAST LATE FRIDAY AND RETURN FLOW WILL
BEGIN FRIDAY NIGHT. LOW PRESSURE OVER THE CENTRAL PLAINS AND
STEEPENING MID LEVEL LAPSE RATES WILL FACILITATE THE
REDEVELOPMENT OF SHOWERS AND THUNDERSTORMS AS ANOTHER COLD FRONT
SINKS SOUTH. SUPERCELLS WILL BE POSSIBLE INITIALLY SATURDAY
BEFORE CONGEALING INTO CLUSTERS OR COMPLEXES AND CONTINUING INTO
SATURDAY NIGHT. ALL SEVERE WEATHER HAZARDS ARE POSSIBLE,
INCLUDING FLASH FLOODING.
THE COLD FRONT WILL PASS THROUGH AND EXIT TO THE SOUTH BY
SUNDAY. COOLER AND DRIER AIR WILL USHER IN WITH A LARGE TROUGH
ACROSS THE NORTHERN AND EASTERN U.S. WEAK SHORTWAVES COULD BRING
OCCASIONAL LOW CHANCES FOR SHOWERS AND THUNDERSTORMS, BUT
NOTHING LOOKS TOO SIGNIFICANT AT THIS TIME.
