- SEASONABLE TEMPERATURES CONTINUE TODAY.
- WARM, ABOVE-NORMAL TEMPERATURES AND DRY CONDITIONS EXPECTED NEXT

NEAR TERM
(THROUGH SATURDAY)
ISSUED AT 255 AM CDT SAT OCT 3 2026
AN AREA OF RAIN ACROSS NORTH TEXAS INTO FAR SOUTHERN OKLAHOMA
WILL CONTINUE TO EXPAND TO THE NORTH AS ASCENT ASSOCIATED WITH A
SUBTLE WAVE LIFTS INTO SOUTH CENTRAL AND SOUTHEASTERN OKLAHOMA
LATER THIS MORNING.
WITH ANOMALOUSLY HIGH PRECIPITABLE WATER VALUES PRESENT (~1.8 TO
1.9 INCHES), SOME LOCALLY HEAVY RAINFALL IS POSSIBLE. THE 90TH
PERCENTILE (I.E., REASONABLE WORST CASE SCENARIO) AMONG
CONVECTIVE-ALLOWING MODELS INDICATE THE POTENTIAL FOR ~1 TO 2
INCHES OF RAINFALL NEAR THE RED RIVER. GIVEN THE MOISTURE PRESENT,
THESE POTENTIAL HIGHER-END TOTALS DO NOT SEEM UNREASONABLE.
ALTHOUGH THESE TOTALS ARE UNLIKELY FOR MOST, A FEW ISOLATED
LOCATIONS COULD POTENTIALLY RECEIVE THIS AMOUNT OF RAINFALL WITH
SOME FLOODING RISK. SCATTERED SHOWERS MAY MAKE IT AS FAR NORTHWEST
AS THE I-44 CORRIDOR LATER THIS MORNING, BUT THE HEAVIEST
RAINFALL SHOULD BE CONFINED CLOSER TO THE RED RIVER. THESE SHOWERS
MAY LINGER THROUGH THE AFTERNOON BEFORE THE WAVE EXITS TO THE
EAST.
WITH THE WAVE LIFTING NORTHWARD FROM TEXAS, ABUNDANT CLOUD COVER
WILL LIKELY PERSIST ALONG AND SOUTHEAST OF I-44 TODAY. SEASONABLE
TEMPERATURES FOR EARLY OCTOBER ARE EXPECTED ONCE AGAIN WITH HIGHS
GENERALLY IN THE 70S TO NEAR 80 DEG F.
MAHALE
SHORT TERM
(SATURDAY NIGHT THROUGH MONDAY NIGHT)
ISSUED AT 255 AM CDT SAT OCT 3 2026
SOME PATCHY FOG IS EXPECTED EARLY SUNDAY MORNING WITH WINDS
BECOMING LIGHT AND VARIABLE WITH A SATURATED BOUNDARY LAYER.
OTHERWISE, DECREASING CLOUD COVER ON SUNDAY WILL RESULT IN A
WARMER AFTERNOON WITH HIGH TEMPERATURES RANGING FROM THE MID 70S
TO THE MID 80S DEG F. SIMILAR CONDITIONS ARE EXPECTED ON MONDAY.
NORTHERLY WINDS BOTH DAYS WILL KEEP TEMPERATURES FROM RISING TOO
QUICKLY EVEN WITH MORE SUNSHINE. DRY CONDITIONS ARE EXPECTED BOTH
DAYS.
WITH THE RELATIVELY DRY AIR MASS STILL IN PLACE WITH NORTHERLY
WINDS, LOW TEMPERATURES MONDAY MORNING AND TUESDAY MORNING WILL
BE IN THE 50S DEG F FOR MOST LOCATIONS. SOME SPOTS ACROSS NORTHERN
OKLAHOMA MAY EVEN SEE LOWS IN THE UPPER 40S DEG F.
MAHALE
LONG TERM
(TUESDAY THROUGH FRIDAY)
ISSUED AT 255 AM CDT SAT OCT 3 2026
ABOVE-NORMAL TEMPERATURES AND DRY CONDITIONS ARE EXPECTED NEXT
WEEK AS THE WESTERLIES RETREAT NORTHWARD WITH A STRENGTHENING LOW-
LEVEL THERMAL RIDGE AND THE RETURN TO SOUTHERLY WINDS.
TEMPERATURE SPREAD AMONG BIAS-CORRECTED PROBABILISTIC GUIDANCE
REMAINS MINIMAL, WITH EVEN THE 10TH PERCENTILE INDICATING WARM,
ABOVE-NORMAL TEMPERATURES THROUGH THE END OF THE WEEK. BOTH
DETERMINISTIC AND ENSEMBLE GUIDANCE POINT TO AN ELONGATED MID-
LEVEL RIDGE (~585-587 DAM) AS THE PRIMARY INFLUENCE OF THE WEATHER
ACROSS THE SOUTHERN PLAINS. HIGH TEMPERATURES TOWARD THE END OF
THE WEEK ARE FORECAST TO CLIMB TOWARD OR EVEN EXCEED 90 DEG F.

AVIATION
(18Z TAFS)
ISSUED AT 1159 AM CDT SAT OCT 3 2026
A PERSISTENT STRATUS SHIELD WILL OFFER REDUCED CATEGORY AT
TERMINALS ALONG-EAST OF INTERSTATE 44 THROUGH MUCH OF THE PERIOD.
SOME TEMPORARY "IMPROVEMENT" (TO VFR) IS POSSIBLE ALONG THE
WESTERN PERIPHERY (I.E., KOKC/KLAW/KSPS) PRIOR TO SUNSET BEFORE
THE RETURN OF MORE PERSISTENT MVFR TO IFR CONDITIONS INTO SUNDAY
MORNING.
POTENTIAL FOR PREDAWN RADIATIONAL FOG DEVELOPMENT REMAINS FOCUSED
FURTHER WEST ACROSS OKLAHOMA AND NORTH TEXAS, WHERE SKIES ARE
LIKELY TO REMAIN CLEARER AND SURFACE WINDS LIGHTER INTO SUNDAY
MORNING. LOCAL VIS REDUCTIONS <1 MILE APPEAR POSSIBLE AFTER 09-10
UTC.
MOST TERMINALS ARE CURRENTLY EXPECTED TO TRANSITION BACK TO VFR
CATEGORY BY 15-17 UTC ON SUNDAY, AS FOG DISSIPATES AND ANY
REMAINING STRATUS BEGINS TO "SCATTER OUT".
SAFE TRAVELS!
