SHORT TERM
(THROUGH TONIGHT )
ISSUED AT 1136 AM CDT MON AUG 31 2026
HOT CONDITIONS WILL CONTINUE THROUGH THE AFTERNOON AND EVENING
ACROSS THE ENTIRE FORECAST AREA. AFTERNOON HIGHS WILL AGAIN REACH
THE UPPER 90S TO LOW 100S. DUE TO ONGOING DROUGHT CONDITIONS, DEW
POINTS WILL REMAIN DEPRESSED, MOSTLY IN THE LOW TO MID 60S.
AFTERNOON HEAT INDICES WILL REACH 105-107 F WITHIN THE HEAT ADVISORY
ACROSS NORTHEAST OK AND WEST-CENTRAL AR. OTHERWISE, MOSTLY CLEAR
SKIES AND BREEZY SOUTHERLY WINDS WILL PERSIST.
TONIGHT WILL BE MILD AND QUIET WITH LIGHT SOUTHERLY WIND AND MOSTLY
CLEAR CONDITIONS. LOW TEMPERATURES WILL BE SIMILAR TO LAST NIGHT,
AND MAINLY IN THE 70S.
LONG TERM
(TOMORROW THROUGH MONDAY)
ISSUED AT 1136 AM CDT MON AUG 31 2026
THE PATTERN WILL REMAIN STAGNANT OVER THE NEXT WEEK WITH A SPRAWLING
AND STRONG UPPER LEVEL HIGH EITHER OVERHEAD OR NEARBY. TEMPERATURES
WILL REMAIN CONSISTENT, WITH HIGHS IN THE UPPER 90S TO LOW 100S EACH
DAY AND LOWS MOSTLY IN THE 70S. DEW POINTS WILL REMAIN IN THE LOW TO
MID 60S THROUGH TUESDAY, SO EVEN THOUGH TEMPERATURES WILL BE HOT,
HEAT INDICES WILL ONLY RUN SLIGHTLY HIGHER THAN THE TEMPERATURES.
THIS WILL CONTINUE TO KEEP HEAT PRODUCTS CONFINED TO THE TYPICALLY
HOTTER LOCATIONS. FOR TUESDAY, THE HEAT ADVISORY WILL SPAN THE LOWER
ELEVATIONS OF NORTHEAST OK AND WEST-CENTRAL AR.
BY WEDNESDAY AND ONWARDS, THE LOW LEVEL FLOW WILL BECOME MORE
SOUTHEASTERLY AND STRENGTHEN SLIGHTLY AS A WEAK DECAYING TROPICAL
SYSTEM MOVES INTO TEXAS, WHICH WILL HELP LOW LEVEL MOISTURE CREEP
UPWARDS. THE CHANCE FOR RAIN IS ESSENTIALLY ZERO THROUGH THE WORK
WEEK FOR MOST LOCATIONS. THE ONE EXCEPTION WILL BE PARTS OF
SOUTHEAST OK ON THURSDAY, AS THE REMNANTS OF THE TROPICAL SYSTEM
GRAZE SOUTHEAST OK, BRINGING A 10-15% CHANCE OF A FEW SHOWERS.
A SIMILAR 5-10% CHANCE OF DIURNAL SHOWERS IS POSSIBLE FOR THE
HIGHER TERRAIN OF NORTHWEST AR NEXT WEEKEND AS THE UPPER LEVEL
FLOW BECOMES NORTHWESTERLY. IN ANY CASE, MEANINGFUL PRECIPITATION
REMAINS EXTREMELY UNLIKELY FOR NOW. WITH CONTINUED HOT, DRY, AND
BREEZY WEATHER, SOME FIRE WEATHER POTENTIAL WILL EXIST EACH
AFTERNOON THROUGHOUT THE REGION.
