SHORT TERM
(THROUGH FRIDAY)
ISSUED AT 1147 PM CDT THU OCT 1 2026
SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE TO
DEVELOP ACROSS PORTIONS OF EASTERN OKLAHOMA AND WESTERN ARKANSAS
THROUGH THE NIGHT AS THE UPPER TROUGH AXIS MOVES THROUGH THE
REGION. MEAGER INSTABILITY AND SHEAR WILL KEEP AWAY THE THREAT OF
ANY SEVERE WEATHER. THE MAIN IMPACT THROUGH DAYBREAK WILL BE
LOCALLY HEAVY RAINFALL AS DEEP MOISTURE REMAINS ENTRENCHED OVER
MUCH OF THE SOUTHERN PLAINS. UPWARDS OF AN INCH TO TWO INCHES OF
ADDITIONAL RAINFALL WILL BE POSSIBLE, ESPECIALLY ACROSS SOUTHEAST
OKLAHOMA INTO WEST CENTRAL ARKANSAS. CURRENT SURFACE ANALYSIS ALSO
SHOWS A COLD FRONT CURRENTLY MOVING INTO NORTHEAST OKLAHOMA.
SHOWERS AND POSSIBLY A STORM WILL BE POSSIBLE ALONG THE BOUNDARY
TONIGHT INTO THE EARLY MORNING HOURS. MUCH OF THE RAIN BEGINS TO
EXIT THE AREA DURING THE AFTERNOON HOURS FRIDAY AS THE COLD FRONT
WORKS ITS WAY SOUTH OF THE RED RIVER BY FRIDAY EVENING.
THE COLD FRONT WILL BRING MORE FALL-LIKE TEMPERATURES ALONG WITH
GUSTY NORTHERLY WINDS, ESPECIALLY ACROSS NORTHEAST OKLAHOMA, ON
FRIDAY AS HIGHS STAY IN THE LOWER 70S FOR MOST LOCATIONS NORTH OF
I-40.

LONG TERM
(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 1147 PM CDT THU OCT 1 2026
THE MID LEVEL TROUGH WILL BEGIN TO SHIFT EAST OF THE LOCAL REGION
BY FRIDAY EVENING, THOUGH THE ELONGATED TROUGH AXIS WILL LINGER IN
THE VICINITY THROUGH THE DAY SATURDAY AS ANOTHER WEAK WAVE DROP
SOUTHEAST. THIS WILL BE ENOUGH TO SPARK MORE SCATTERED SHOWERS AND
POSSIBLY A THUNDERSTORM, MAINLY SOUTH OF I-40, THROUGH SATURDAY
AFTERNOON. RAINFALL AMOUNT WILL TEND TO BE LIGHT OVERALL WITH ANY
ACTIVITY ON SATURDAY AS DRIER AIR BEGINS TO SPILL INTO THE REGION.
A REINFORCING COLD FRONT DROPS INTO THE AREA ON SUNDAY FINALLY
CLEARING THINGS OUT THROUGH SUNDAY AFTERNOON. A MODEST CANADIAN
SURFACE HIGH WILL SETTLE INTO THE AREA THROUGH THE EARLY PART OF
NEXT WEEK, WITH SOME OF THE COOLEST OVERNIGHT LOWS WE HAVE SEEN
SINCE THE SPRING LOOKING LIKELY. WIDESPREAD LOWS IN THE 50S WILL
BE COMMON THE FIRST PART OF NEXT WEEK, WHILE SOME OF THE NORMALLY
COOLER LOCATIONS ACROSS THE NORTH COULD DIP INTO THE UPPER 40S,
ESPECIALLY TUESDAY MORNING.
TEMPERATURES BEGIN TO STEADILY TREND WARMER THROUGH THE LATTER
PART OF THE WEEK AS MID LEVEL RIDGING BUILDS BACK STRONGER OVER
THE SOUTHWESTERN CONUS. HIGHS WILL CLIMB BACK INTO THE 80S
AREAWIDE WHILE DRY WEATHER PREVAILS THROUGH THE BACK HALF OF THE
FORECAST PERIOD.
