- UNSETTLED WEATHER OVER THE WEEKEND WITH MULTIPLE ROUNDS OF
THUNDERSTORMS. HIGHEST CHANCES WILL BE THIS EVENING INTO THE
OVERNIGHT HOURS, AND AGAIN SUNDAY LATE MORNING INTO THE
AFTERNOON.
- LOW TO MEDIUM CHANCE FOR STRONG STORMS THROUGH THE WEEKEND,
STRONG WIND GUSTS WILL BE THE MAIN CONCERN ALONG WITH HEAVY
RAIN.

THE ACTIVE AND WET PATTERN WILL RETURN FOR THE SECOND HALF OF

SHORT TERM
(REST OF TODAY THROUGH SUNDAY)
ISSUED AT 1054 AM CDT SAT JUN 13 2026
CAMS CONTINUE TO STRUGGLE ON TIMING OF SHOWERS AND THUNDERSTORMS
THROUGH THE WEEKEND, BUT THEY ALL AGREE THAT A CLUSTER OF STRONGER
THUNDERSTORMS WILL IMPACT THE MID STATE THIS EVENING INTO THE
OVERNIGHT HOURS, AND A LOWER CHANCE SUNDAY AFTERNOON. LARGELY
ZONAL PATTERN ALOFT IS KEEPING MORE WIDESPREAD CHANCES FOR STORMS
AT BAY, BUT SUBTLE SHORTWAVES ARE WHAT'S DRIVING THE INCREASED
CHANCES LATE THIS AFTERNOON THROUGH SUNDAY. THE FIRST WAVE WILL
RACE EASTWARD FROM MO INTO THE OH VALLEY, AND RIGHT NOW CAM
CONSENSUS IS MID EVENING ARRIVAL OF A CLUSTER OF STRONGER STORMS
WITH DAMAGING WINDS AND HEAVY RAINFALL AS THE MAIN THREATS. LOW
CONFIDENCE ON HOW FAR EAST THE STORMS WILL MAKE IT, BUT ENOUGH
INSTABILITY IS IN PLACE TO CARRY THEM AT LEAST PAST I-65, BUT ALL
CAMS SEEM TO WANT TO WEAKEN THE STORMS AS THEY APPROACH THE
PLATEAU. THERE MAY BE A LULL IN ACTIVITY SUNDAY MORNING BEFORE
DAYTIME HEATING AND THE NEXT SHORTWAVE CAN KICK OFF ADDITIONAL
SHOWERS AND STORMS MID DAY THROUGH THE AFTERNOON SUNDAY. DAMAGING
WINDS AND HEAVY RAINFALL WOULD REMAIN THE THREATS, AND HIGHER PWAT
VALUES WILL ALLOW FOR FLOODING POTENTIAL, ESPECIALLY IN AREAS THAT
SEE MULTIPLE ROUNDS OF RAIN.
LONG TERM
(SUNDAY NIGHT THROUGH NEXT SATURDAY)
ISSUED AT 1054 AM CDT SAT JUN 13 2026
A BREAK IN THE SHOWERS AND STORMS WILL START THE WORK WEEK AS MOST
MODELS HAVE SHOWERS AND STORMS TO OUR NORTH AND SOUTH WITH A BROAD
TROUGH OVERHEAD. BUT, SHORTWAVES EMBEDDED WITHIN THE UPPER FLOW
WILL DIG THE TROUGH FURTHER SOUTH, AND ALLOW FOR STORMS TO RETURN
STARTING WEDNESDAY AFTERNOON. THE ACTIVE PATTERN WILL CONTINUE,
WITH EVEN LOW CHANCES FOR MORE STRONG TO SEVERE STORMS WEDNESDAY
AND THURSDAY. STILL TOO EARLY TO CALL ON TIMING OR INTENSITY BUT
THIS ACTIVE PATTERN WILL CONTINUE REGARDLESS. THERE COULD BE
ANOTHER BREAK IN WIDESPREAD SHOWERS AND STORMS FRIDAY AND
SATURDAY, WITH MAINLY JUST A DIURNAL THREAT FOR STORMS, BUT LONG
TERM MODELS CONTINUE TO SHOW HIGH AMOUNTS OF QPF, SUGGESTING THAT
THE OVERALL WET PATTERN WILL PERSIST INTO THE LAST WEEK OF JUNE.
STAYING IN THIS ZONAL/BROAD TROUGH PATTERN WITH EMBEDDED
SHORTWAVES WILL KEEP SHOWERS AND STORMS IN THE FORECAST.
