(TODAY AND TONIGHT)
ISSUED AT 133 PM CST WED FEB 25 2026
THE WEAK SURFACE LOW HAS MOVED VERY SLOWLY SOUTHEASTWARD THIS
MORNING, AND IS CURRENTLY CENTERED NEAR BOWIE TX. AS A RESULT,
OBSERVATION MAPS SHOW LIGHT SOUTHERLY WINDS OVER FAR SOUTHEASTERN
OKLAHOMA AND NORTHEAST WINDS OVER MOST OF OUR OKLAHOMA COUNTIES.
AS A RESULT, THE CYCLONIC FLOW HAS ADVECTED A MORE MOIST AIR MASS
INTO THE AREA. MESONET OBS SHOW DEWPOINT TEMPERATURES HAVE RISEN
INTO THE LOW 50'S OVER SOUTHEASTERN OKLAHOMA.
SCATTERED TO BROKEN CIRRUS WILL CONTINUE TO STREAM ACROSS THE AREA
AND AFTERNOON TEMPERATURES ARE EXPECTED TO BE IN THE 70'S. A WEAK
COLD FRONT ENTERS THE AREA THIS EVENING, MARKED WITH A BRIEF INCREASE
IN GUSTY NORTH WINDS, AND EXITS BY EARLY THURSDAY MORNING. RAIN
CHANCES WITH THIS SYSTEM HAVE DROPPED TO LESS THAN 10 PERCENT.

SHORT TERM
(THURSDAY THROUGH FRIDAY NIGHT)
ISSUED AT 133 PM CST WED FEB 25 2026
THE SURFACE HIGH THEN TRANSLATES ACROSS KANSAS AND LIGHT/MODERATE
NORTH WINDS AT 5 TO 15 MPH ALONG WITH WEAK CAA WILL KEEP HIGHS
NEAR 70 DEG OVER NORTHERN OKLAHOMA ON THURSDAY. HIGH TEMPERATURES
WILL RISE INTO THE UPPER 70'S OVER FAR SOUTHERN OKLAHOMA AND NORTH
TEXAS. AFTERNOON RELATIVE HUMIDITY (RH) WILL DECREASE TO 20 TO 25
PERCENT OVER PART OF NORTHWEST OKLAHOMA, BUT WINDS WILL BE GENERALLY
LIGHT. THEREFORE, THE FIRE WEATHER RISK HAS DECREASED AND EXPECTED
TO BE LOW.
LIGHT WINDS BEGIN TO VEER TO THE SOUTHEAST ON THURSDAY NIGHT AS THE
HIGH PRESSURE SYSTEM REACHES THE MISSISSIPPI RIVER VALLEY. WITH THE
RETURN TO SOUTHERLY WINDS, WARMER CONDITIONS ARE EXPECTED ON FRIDAY,
WITH WIDESPREAD HIGHS IN THE UPPER 70'S. RH VALUES WITHIN THE 20 TO
30% RANGE WILL BE COMMON BY FRIDAY AFTERNOON. WITH THE H500 SPEED
MAXIMA PASSING SOUTH OF OUR FA, S/SE WINDS WILL BE ON THE LIGHTER
SIDE ON FRIDAY AFTERNOON WITH WINDS UP TO 15 MPH OVER NORTHWEST AND
WESTERN OKLAHOMA. THEREFORE, THE ELEVATED FIRE RISK ON FRIDAY APPEARS
LOW AND WILL CONTINUE TO MONITOR MODEL TRENDS, IN THIS REGARD.

LONG TERM
(SATURDAY THROUGH TUESDAY)
ISSUED AT 142 AM CST WED FEB 25 2026
THE LAST DAY OF FEBRUARY WILL NOT FEEL LIKE LATE WINTER, AS
TEMPERATURES WILL RANGE FROM THE UPPER 70S TO MID 80S. NOT ONLY
WILL IT BE VERY WARM, BUT THERE WILL BE A HINT OF HUMIDITY IN THE
AIR, ESPECIALLY ACROSS SOUTHERN OKLAHOMA AND NORTHERN TEXAS.
HOWEVER, GUIDANCE HAS BEEN FAIRLY CONSISTENT IN BRINGING A COLD
FRONT INTO THE AREA LATE SATURDAY INTO SUNDAY. HOW QUICKLY THE
SHALLOW, COLDER AIR OVERSPREADS OKLAHOMA AND NORTHERN TEXAS IS
UNCERTAIN. THIS UNCERTAINTY IS PRODUCING A 40 DEGREE SPREAD IN
HIGH TEMPERATURE GUIDANCE FOR OKLAHOMA CITY SUNDAY. FOR EXAMPLE,
THE WARMER SIDE OF GUIDANCE PREDICTS A HIGH OF 85 DEGREE WHILE THE
LOWER SIDE IS 45 DEGREES. TYPICALLY, THESE SHALLOW AIRMASSES WILL
ARRIVE EARLIER THAN MODELS SUGGEST. FOR NOW WILL STICK WITH A
BLEND OF THE MODEL SOLUTIONS, BUT WOULDN'T BE SURPRISED IF LATER
FORECAST TREND COOLER SUNDAY INTO MONDAY.
THE MID AND UPPER LEVEL FLOW IS EXPECTED TO BECOME MORE WEST TO
SOUTHWEST EARLY NEXT WEEK. THIS ALONG WITH A FRONT TO OUR SOUTH
WILL INCREASE THE CHANCES OF RAIN AND PERHAPS ELEVATED STORMS. THE
GOOD NEWS IS WE ARE FINALLY MENTIONING A CHANCE OF RAIN IN THE
FORECAST.

COLD FRONT HAS ENTERED THE OKLAHOMA PANHANDLE, BUT HAS YET TO MAKE
IT TO THE FAR NORTHWESTERN AIRPORTS. THAT WILL CHANGE OVER THE
NEXT FEW HOURS, AS NORTHWEST WINDS BEGIN TO SPILL ACROSS THE AREA.
VFR CEILINGS WILL PREVAIL AT ALL SITES, EXCEPT MAYBE DUA. SOME LOW
CLOUDS MAY MAKE THEIR WAY INTO THE RED RIVER COUNTIES TOWARDS
DAYBREAK.
