SHORT TERM
(THROUGH TONIGHT)
ISSUED AT 1207 PM CDT SAT JUL 11 2026
CONTINUED HOT AND HUMID CONDITIONS AND INCREASING POTENTIAL FOR
LOCALIZED SEVERE WEATHER AND HEAVY RAINFALL DOMINATE THE WEATHER
CONCERNS THROUGH TONIGHT. AN OUTFLOW BOUNDARY REMAINS STRETCHED
ACROSS PARTS OF NORTHEAST OKLAHOMA JUST TO THE SOUTH OF THE KANSAS
BORDER EASTWARD INTO SOUTHWEST MISSOURI. AS EXPECTED, DEW POINTS
HAVE INCREASED ALONG AND SOUTH OF THE BOUNDARY, WITH VALUES MAINLY
IN THE MID 70S AREAWIDE AND RUNNING A FEW DEGREES HIGHER THAN THIS
SAME TIME YESTERDAY. HIGHEST CONFIDENCE IN ADVISORY LEVEL HEAT
INDEX VALUES REMAINS COVERED BY THE EXISTING ADVISORY AND NO
CHANGES ARE PLANNED AT THIS TIME. WILL HAVE TO WATCH TRENDS IN CREEK
AND OKFUSKEE COUNTIES, WHICH MAY GET CLOSE TO 105 BEFORE ALL IS
SAID AND DONE THIS AFTERNOON.
EARLY TO MID AFTERNOON THUNDERSTORM DEVELOPMENT REMAINS MOST
LIKELY ACROSS PORTIONS OF NORTHWEST ARKANSAS, PRIMARILY EAST OF
I-49, DUE TO THE CLOSEST PROXIMITY TO THE UPPER LEVEL DISTURBANCE
MOVING EAST-SOUTHEASTWARD THROUGH CENTRAL AND EASTERN MISSOURI.
MORE SCATTERED TO NUMEROUS DEVELOPMENT NEAR THE AFOREMENTIONED
BOUNDARY BECOMES MORE LIKELY LATE AFTERNOON AND INTO THE EVENING
ACROSS NORTHEAST OKLAHOMA AND INTO NORTHWEST ARKANSAS. THE TIMING
OF THIS DEVELOPMENT IS LATER THAN REFLECTED IN EARLIER FORECASTS,
WITH THE HIGHER POPS DELAYED UNTIL AFTER 00Z. LOCALLY DAMAGING
WINDS REMAIN THE PRIMARY SEVERE WEATHER THREAT, ALTHOUGH WITH THE
EXPECTATION OF A SLIGHT UPTICK IN DEEP LAYER SHEAR, THE THREAT FOR
MARGINALLY SEVERE HAIL WILL ALSO EXIST. WITH PRECIPITABLE WATER
VALUES FROM 1.75 TO 2 INCHES IN MUCH OF THE AREA, LOCALLY HEAVY
RAINFALL WILL BE A CONCERN, ESPECIALLY WHERE MULTIPLE ROUNDS OF
THUNDERSTORMS OCCUR. AT LEAST SCATTERED THUNDERSTORMS WILL PERSIST
INTO EARLY SUNDAY MORNING, MAINLY ACROSS SOUTHEAST OKLAHOMA AND
INTO WEST CENTRAL ARKANSAS, ALTHOUGH THE CHANCE FOR SEVERE WEATHER
SHOULD BE DECREASED.
LONG TERM
(TOMORROW THROUGH SATURDAY)
ISSUED AT 1207 PM CDT SAT JUL 11 2026
A FEW SHOWERS AND THUNDERSTORMS WILL LIKELY BE ONGOING SUNDAY
MORNING ACROSS AREAS ALONG AND SOUTH OF I-40. ADDITIONAL STRONG TO
MARGINALLY SEVERE STORMS WILL BE POSSIBLE SUNDAY AFTERNOON IN
AREAS NEAR THE RED RIVER NEAR A SURFACE BOUNDARY AND A SLOW MOVING
DISTURBANCE IN THE REGION. ACROSS A GOOD CHUNK OF THE AREA,
SLIGHTLY COOLER AND DRIER CONDITIONS WILL MOVE IN SUNDAY, BRINGING
AN END TO THE CURRENT STRETCH OF HEAT AND HUMIDITY. THE NEED FOR
ADDITIONAL HEAT ADVISORIES ON SUNDAY APPEARS VERY LOW AT THIS
TIME. INTO MONDAY, LOW CHANCES FOR SHOWERS AND THUNDERSTORMS WILL
REMAIN FOCUSED NEAR THE RED RIVER AND NEAR NORMAL TEMPERATURES
WILL PREVAIL DURING THE AFTERNOON. THE OVERALL DETAILS IN THE
WEATHER PATTERN TOWARD THE MIDDLE TO LATTER PART OF THE WEEK
REMAIN SOMEWHAT UNCERTAIN, WITH THE POTENT UPPER HIGH CENTERED
ACROSS THE NORTHERN PLAINS AND EASTERLY FLOW ALOFT ACROSS THE
AREA. GIVEN THE POSITION OF THE UPPER HIGH, THE AREA SHOULD REMAIN
OUT OF EXTREME HEAT FOR MUCH OF NEXT WEEK. LOW SHOWER AND
THUNDERSTORM CHANCES WILL CONTINUE, PARTICULARLY DURING THE
AFTERNOONS AND IN THE MORE FAVORED, HIGHER TERRAIN AREAS. LATE IN
THE WEEK AND INTO NEXT WEEKEND, THE UPPER LEVEL HIGH LOOKS TO
SHIFT TO THE SOUTH AND WEST, PUTTING THE REGION IN A MORE
FAVORABLE PATTERN FOR ABOVE NORMAL TEMPERATURES ONCE AGAIN.
