KEY MESSAGES
UPDATED AT 559 AM CDT THU AUG 20 2026
- SLIGHT COOLING IS EXPECTED FOR SOME AREAS THURSDAY, BUT
TEMPERATURES WILL REMAIN ABOVE AVERAGE, WITH SLIGHT WARMING
RETURNING INTO THE WEEKEND.
- ISOLATED SHOWERS MAY OCCUR AT TIMES FOR THE NEXT SEVERAL DAYS,
BUT OVERALL DRY WEATHER WILL CONTINUE.
- FIRE WEATHER CONDITIONS REMAIN A DAILY CONCERN DUE TO DRYING
FUELS AND PERIODS OF GUSTY WINDS.
SHORT TERM
(THROUGH THURSDAY)
ISSUED AT 1050 PM CDT WED AUG 19 2026
TEMPERATURES WILL REMAIN VERY MILD OVERNIGHT, BUT WITH SOME COOLING
IN THE NORTH BEHIND THE COLD FRONT. LOWS WILL RANGE FROM THE LOW 70S
IN THE NORTH TO NEAR 80 ACROSS SOUTHEAST OKLAHOMA. THE COLD FRONT
WILL GRADUALLY MOVE SOUTH, STALLING SOMEWHERE ACROSS SOUTHEAST
OKLAHOMA TO PERHAPS AS FAR AS THE RED RIVER. A FEW SHOWERS AND
STORMS MAY DEVELOP NEAR THE ELEVATED FRONTAL BOUNDARY OVERNIGHT.
THESE ISOLATED STORMS MAY PRODUCE BRIEF GUSTY WINDS AND HEAVY
RAIN, BUT TOTALS WILL LIKELY STAY MINIMAL.
THURSDAY WILL BE SEVERAL DEGREES COOLER THAN WEDNESDAY, BUT STILL
WELL ABOVE NORMAL. HIGHS WILL MOSTLY BE IN THE UPPER 90S IN THE
NORTH AND LOW 100S IN THE SOUTH. FAR SOUTHERN OKLAHOMA WILL SEE
LITTLE COOLING IMPACT SO AN EXTREME HEAT WARNING REMAINS IN EFFECT
THERE FOR THE AFTERNOON HOURS, WITH A HEAT ADVISORY EXTENDING NORTH
TO A LITTLE NORTH OF I-40. SOME CAMS INDICATE A RESURGENCE OF
SHOWERS AND STORMS NEAR THE DYING COLD FRONT DURING THE AFTERNOON
HOURS, SO RAISED NBM POPS TO MENTIONABLE IN THE SOUTH.
LONG TERM
(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 1050 PM CDT WED AUG 19 2026
THE UPPER LEVEL RIDGE WILL REMAIN TO THE WEST OF THE AREA THE NEXT
SEVERAL DAYS, BUT PLENTY CLOSE ENOUGH TO KEEP VERY HOT TEMPERATURES
IN PLACE. TEMPERATURES WILL REMAIN WELL ABOVE NORMAL THROUGH THE
NEXT WEEK, GENERALLY IN THE LOW 100S ACROSS EASTERN OK AND WEST-
CENTRAL AR, WITH UPPER 90S IN NORTHWEST AR. MID LEVEL FLOW WILL
INCREASE SLIGHTLY FRIDAY THROUGH AT LEAST MONDAY AS A SERIES OF
WEAK SHORTWAVES PASS THROUGH THE AREA. THESE SHORTWAVES WILL
PROMOTE JUST ENOUGH LIFT FOR THE RISK OF A FEW SHOWERS AND
THUNDERSTORMS, THOUGH COVERAGE WILL PROBABLY REMAIN ISOLATED AND
FOCUSED ACROSS NORTHWEST ARKANSAS.
HEADING INTO THE MIDDLE OF NEXT WEEK MOST GUIDANCE KEEPS THE RIDGE
WEST OF THE AREA, WHICH WOULD KEEP HOT WEATHER IN PLACE BUT WITH A
SLIGHT CHANCE OF SHOWERS PERSISTING AT TIMES. OTHER GUIDANCE
MOVES THE RIDGE OVERHEAD WHICH WOULD BE SLIGHTLY HOTTER AND END
ANY CHANCE OF PRECIPITATION. THE MOST LIKELY OUTCOME IS A
CONTINUATION OF THE SAME PATTERN WITH HOT AND MOSTLY DRY
CONDITIONS, BUT PERIODIC SLIGHT CHANCES OF RAIN. IN NET, THIS
MEANS A CONTINUED DRYING OF FUELS AND INCREASING FIRE WEATHER
POTENTIAL FOR MANY AREAS OVER TIME.
AVIATION
(12Z TAFS)
ISSUED AT 607 AM CDT THU AUG 20 2026
BAND OF HIGHER BASED SHOWERS AND STORMS WILL PROGRESS TOWARD KFSM
AND KMLC THIS MORNING. WENT WITH VCSH PREVAILING AND A PROB30
TSRA MENTION AT KFSM ONLY (KMLC LOWER CHANCE GIVEN PLACEMENT AND
MOVEMENT) FOR THIS ACTIVITY THROUGH MID-MORNING. LATEST CAMS
SUGGEST SOME CHANCE FOR AFTERNOON STORM DEVELOPMENT CLOSE TO KMLC
AND KFSM AS WELL SO AN ADDITIONAL PROB30 WAS ADDED TO COVER
POTENTIAL. GUIDANCE ALSO INDICATES CHANCES FOR ELEVATED SHOWERS
AND SOME THUNDER LATE TONIGHT ACROSS NORTH-CENTRAL OK. WITH
CONFIDENCE LOW, JUST INCLUDED VCSH MENTION AT THE NE OK SITES FOR
NOW. OUTSIDE OF ANY DIRECT STORM IMPACT AT A TERMINAL, VFR
CONDITIONS WILL PREVAIL WITH SFC WINDS BLO IMPACTFUL LEVELS.
