SHORT TERM
(TODAY)

AN UPPER LEVEL DISTURBANCE MOVING THROUGH THE NORTHWEST FLOW
ALOFT WILL BRING SCATTERED SHOWERS AND THUNDERSTORMS TODAY,
MAINLY ACROSS EASTERN OKLAHOMA. SOME LOCALLY HEAVY RAINFALL WILL
BE POSSIBLE, ESPECIALLY ACROSS PARTS OF NORTHEAST OKLAHOMA.
TEMPERATURES WILL REMAIN WELL BELOW NORMAL, WITH AFTERNOON HIGHS
IN THE LOW TO MID 80S IN MOST PLACES, AND SOME UPPER 80S POSSIBLE
IN THE ARKANSAS RIVER VALLEY.
LONG TERM
(TONIGHT THROUGH SUNDAY)
ISSUED AT 1238 AM CDT SUN AUG 31 2025
A STRONGER UPPER LEVEL DISTURBANCE WILL MOVE SOUTHEAST ACROSS THE
AREA MONDAY AND MONDAY NIGHT, ACCOMPANIED BY A COLD FRONT.
SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED WITH THIS SYSTEM
AS WELL, WITH LOCALLY HEAVY RAINFALL AGAIN POSSIBLE. SHOWER AND
STORM CHANCES WILL CONTINUE INTO TUESDAY ACROSS MAINLY NORTHWEST
ARKANSAS, AND TEMPERATURES WILL REMAIN WELL BELOW NORMAL.
AFTER A BRIEF WARMUP AND A DRY DAY WEDNESDAY, SHOWER AND STORM
CHANCES WILL RETURN WEDNESDAY NIGHT AND THURSDAY AS A STRONGER
COLD FRONT MOVES ACROSS THE AREA. OVERALL, THE MODELS ARE NOT AS
AGGRESSIVE WITH THE COOLING BEHIND THIS FRONT, BUT TEMPERATURES
WILL STILL BE MUCH BELOW NORMAL, WITH MOST PLACES REMAINING IN
THE 70S FOR HIGHS THURSDAY AND FALLING INTO THE 50S FOR LOWS
THURSDAY NIGHT.
SOME MODELS, NAMELY THE GFS AND ICON, BRING A REINFORCING SHOT OF
COOLER AIR THROUGH THE AREA FRIDAY, BUT OTHERS DO NOT, SO FORECAST
UNCERTAINTY IS HIGH LATE THIS WEEK THROUGH NEXT WEEKEND. THE
CONSENSUS FAVORS A RETURN OF AT LEAST LOW RAIN CHANCES WITH TIME
AND A SLOW WARMING TREND, BUT WITH TEMPERATURES REMAINING BELOW
NORMAL FOR THE FIRST WEEK OF SEPTEMBER.
