SHORT TERM
(THROUGH THURSDAY)
ISSUED AT 1139 PM CDT WED SEP 9 2026
THE MAIN CONCERNS FOR THE NEXT 18 TO 24 HOURS ARE TWO-FOLD,
STARTING WITH HOW MUCH SHOWER AND THUNDERSTORM COVERAGE WILL OCCUR
FROM EARLY THURSDAY MORNING INTO THE AFTERNOON AND ALSO, WHETHER
ADVISORY LEVEL HEAT INDEX VALUES WILL HANG AROUND PARTS OF
SOUTHEAST OKLAHOMA YET ANOTHER DAY.
LATE THIS EVENING, EVIDENCE OF THE OUTFLOW FROM THE AFTERNOON AND
EARLY EVENING STORMS THAT OCCURRED MAINLY ACROSS SOUTHERN KANSAS
INTO NORTHWEST AND NORTH CENTRAL OKLAHOMA REMAINS ACROSS NORTHEAST
OKLAHOMA, MAINLY NORTH OF HIGHWAY 412. THE MAIN COLD FRONT IS WELL
NORTH OF THE AREA, STRETCHING ACROSS CENTRAL KANSAS. IN THE PAST
COUPLE OF HOURS, THUNDERSTORM COVERAGE HAS EXPANDED IN BETWEEN THE
TWO BOUNDARIES TO THE NORTH OF THE KANSAS STATE LINE IN RESPONSE
TO A MODEST MID LEVEL DISTURBANCE. THROUGH THE MORNING HOURS,
EXPECT A CONTINUED EXPANSION IN THE COVERAGE ALONG WITH A SOUTHWARD
PUSH AS THE SLOW-MOVING COLD FRONT APPROACHES FROM THE NORTH AND
BEGINS TO MOVE THROUGH THE AREA. A VERY LIMITED POTENTIAL FOR
LOCALLY STRONG TO SEVERE WINDS WILL EXIST WITH THE STRONGEST
STORMS TOWARD DAYBREAK, ALONG WITH LOCALLY HEAVY RAINS GIVEN SLOW
STORM MOTIONS AND HIGH PRECIPITABLE WATER VALUES. TOWARD MIDDAY, A
DECREASE IN COVERAGE SHOULD OCCUR, WITH ANOTHER UPTICK IN THE
VICINITY OF THE BOUNDARY DURING THE AFTERNOON, LIKELY FARTHER
SOUTH THAN THE MORNING ACTIVITY. THE AFTERNOON STORMS WILL POSE
ANOTHER LIMITED RISK FOR LOCALLY STRONG TO SEVERE WIND GUSTS.
CONFIDENCE IS LOW REGARDING THE NEED FOR A HEAT ADVISORY FOR PARTS
OF SOUTHEAST OKLAHOMA TOMORROW, WITH THE CURRENT FORECAST
FEATURING HEAT INDEX VALUES THAT ARE VERY MARGINAL FOR A SMALL
PART OF AREAS NEAR THE RED RIVER. ABOVE NORMAL TEMPERATURES ARE
STILL LIKELY, HOWEVER. WILL PASS ALONG CONCERNS TO LATER SHIFTS
BUT WILL NOT ISSUE AN ADVISORY WITH THIS PACKAGE.
LONG TERM
(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 1139 PM CDT WED SEP 9 2026
LATE THURSDAY NIGHT AND INTO FRIDAY MORNING WILL FEATURE A ROUND
OF NOCTURNAL SHOWERS AND THUNDERSTORMS, PARTICULARLY ACROSS PARTS
OF FAR EASTERN OKLAHOMA AND INTO WESTERN ARKANSAS DUE TO ANOTHER
MID LEVEL DISTURBANCE AND A WEAK LOW LEVEL JET ORIENTED TOWARD
THOSE AREAS. POTENTIAL FOR LOCALLY HEAVY RAINS WILL CONTINUE WITH
PRECIPITABLE WATER VALUES AROUND 2 INCHES PERSISTING. THE
POTENTIAL FOR FURTHER DEVELOPMENT DURING THE DAY FRIDAY WILL SHIFT
SOUTH AND EAST, WITH A BRIEF DRY PERIOD BY FRIDAY EVENING. THE
RAINFALL AND RESIDUAL CLOUD COVER DURING THE DAY WILL KEEP
TEMPERATURES MUCH COOLER FRIDAY THAN WHAT THE AREA HAS EXPERIENCED
OF LATE, ALTHOUGH STILL A COUPLE OF DEGREES ABOVE SEASONAL NORMAL
HIGHS.
FOR THE WEEKEND, THE UPPER LEVEL RIDGE LOOKS TO EXPAND BACK OVER
THE REGION, ALTHOUGH BEFORE IT DOES, THERE MAY BE ONE LAST ROUND
OF MORNING SHOWERS AND THUNDERSTORMS SATURDAY MORNING DUE TO A
CENTRAL PLAINS MID LEVEL WAVE. FORECAST HIGHS ARE SOMEWHAT
UNCERTAIN FOR SATURDAY GIVEN THIS POTENTIAL, WITH LONGER LASTING
RAINFALL AND CLOUD COVER LIKELY TO LEAD TO LOWER TEMPERATURES THAN
CURRENTLY FORECAST.
WELL ABOVE NORMAL TEMPERATURES WILL EXTEND INTO THE EARLY PART OF
THE UPCOMING WORK WEEK, WITH POTENTIAL FOR ADDITIONAL HEAT
HEADLINES BOTH OVER THE WEEKEND AND NEXT WEEK. THE MIDDLE PART OF
NEXT WEEK MAY BRING ANOTHER COOLDOWN AND RAINFALL, WITH ANOTHER
COLD FRONT APPROACHING THE AREA. TIMING AND STRENGTH OF THIS FRONT
AND EVEN HOW FAR INTO THE AREA IT MAY MOVE ARE UNCERTAIN BUT IT
BRINGS SOME GLIMMER OF HOPE.
