UPDATE
ISSUED AT 923 AM CDT SUN MAR 15 2026
MADE A QUICK UPDATE TO FIRST PERIOD GRIDS TO BETTER SUPPORT
POTENTIAL FIRE WEATHER OPERATIONS. NUDGED GRIDS TOWARDS THE HRRR
WHICH (A) BRINGS A SHARPER INCREASE TO THE WIND SPEEDS AT THE
FRONT MOVES THROUGH, (B) BRINGS IN LOWER DEWPOINTS QUICKER, AND
(C) COOLS TEMPERATURES ARE LITTLE QUICKER, AT LEAST IN THE NORTH
AND WEST WITH THIS INITIAL SURGE OF COOLER AIR. ALTHOUGH THIS
SOMEWHAT COOLER, SOMEWHAT LOWER DEWPOINTS ACT TO OFFSET EACH
OTHER, THE NET EFFECT WAS THAT FORECAST MINIMUM HUMIDITY VALUES
ARE A LITTLE LOWER, ESPECIALLY IN THE SOUTHWEST.
NEAR TERM
(THROUGH SUNDAY)
ISSUED AT 151 AM CDT SUN MAR 15 2026
QUITE MILD CONDITIONS ARE IN PLACE EARLY THIS MORNING AS A STRONG
LOW-LEVEL JET IS KEEPING THE BOUNDARY LAYER WELL MIXED. SURFACE
ANALYSIS SHOWS A COLD FRONT ACROSS SOUTHERN NEBRASKA THAT IS
FORECAST TO RACE SOUTHWARD THIS MORNING AS A TROUGH AMPLIFIES
ACROSS THE CENTRAL US. VERY STRONG NORTH WINDS AND FALLING
TEMPERATURES ARE EXPECTED BEHIND THE FRONT TODAY. SUSTAINED SPEEDS
OF 30-40 MPH ARE LIKELY WITH GUSTS OVER 60 MPH AT TIMES,
ESPECIALLY ACROSS WESTERN OK INTO WESTERN NORTH TX. BLOWING DUST
IS ALSO LIKELY FOR THESE AREAS AS MUCH OF THE REGION UPSTREAM HAS
SEEN LITTLE RECENT RAINFALL AND VEGETATION REMAINS DORMANT. A
HIGH WIND WARNING IS IN EFFECT FOR MOST OF THE AREA OUTSIDE
SOUTHEAST OK, WHERE A WIND ADVISORY IS IN EFFECT FOR GUSTS OF 40
TO 50 MPH.
FIRE WEATHER WILL ALSO BE A CONCERN TODAY AS EVEN WITH FALLING
TEMPERATURES SUCH INTENSE WINDS AND DRY FUELS WILL MAKE IT MORE
DIFFICULT TO DEAL WITH ANY FIRES THAT START. PERHAPS THE GREATEST
OVERALL FIRE RISK WILL BE ACROSS SOUTHWEST OK AND WESTERN NORTH TX
WHERE NEAR-CRITICAL TO CRITICAL FIRE CONDITIONS ARE EXPECTED AS
TEMPERATURES WILL BE A BIT WARMER AND RELATIVE HUMIDITY A BIT
LOWER FOR THESE AREAS. A RED FLAG WARNING IS IN EFFECT FOR MOST OF
THE AREA ALONG AND WEST OF I-35.
WINDS WILL ONLY GRADUALLY DECREASE THIS EVENING AS IT APPEARS THE
BOUNDARY LAYER WILL TAKE A COUPLE HOURS TO FULLY DECOUPLE AFTER
SUNSET. STRONG COLD ADVECTION WILL MAKE FOR A CHILLY NIGHT TONIGHT
WITH LOWS DROPPING WELL INTO THE 20S FOR MOST OF THE AREA, WITH SOME
TEENS POSSIBLE IN NORTHERN/NORTHWESTERN OK. COMBINED WITH A
LINGERING NORTHERLY BREEZE, IT WILL FEEL 10-15 DEGREES COLDER IN
MOST SPOTS.

SHORT TERM
(SUNDAY NIGHT THROUGH TUESDAY NIGHT)
ISSUED AT 151 AM CDT SUN MAR 15 2026
THE AREA WILL REMAIN UNDER THE INFLUENCE OF SURFACE RIDGING MONDAY
WITH NORTH-NORTHWEST WINDS KEEPING TEMPERATURES IN THE MID 40S TO
MID 50S FOR HIGHS. WINDS WILL VEER BACK TO THE SOUTH BY TUESDAY,
HELPING BOOST HIGHS BACK ABOVE AVERAGE INTO THE 60S AND 70S. WILL
HAVE TO WATCH FOR A FIRE WEATHER RISK TUESDAY WITH POTENTIAL FOR A
DRY RETURN FLOW SETUP CREATING ELEVATED TO NEAR-CRITICAL FIRE
WEATHER.
WARE
LONG TERM
(WEDNESDAY THROUGH SATURDAY)
ISSUED AT 151 AM CDT SUN MAR 15 2026
THE WARMING TREND WILL CONTINUE IN EARNEST THROUGH THE MIDDLE TO END
OF NEXT WEEK AS STRONG UPPER RIDGING (NEARLY 600 DM AT 500 MB)
BUILDS ACROSS THE WESTERN/CENTRAL US. MODEL DATA CONTINUES TO
POINT TOWARDS THE POTENTIAL FOR RECORD HEAT ACROSS THE AREA WITH
WIDESPREAD 90+ DEGREE TEMPS LIKELY AND 100 DEGREES NOT OUT OF THE
QUESTION ACROSS SOUTHWEST OK AND WESTERN NORTH TX. REMARKABLY,
EVEN THE 50TH PERCENTILE NBM WOULD CHALLENGE THE ALL-TIME MARCH
HIGH TEMPERATURE RECORDS THURSDAY THROUGH SATURDAY, WITH 90TH
PERCENTILE VALUES WELL OVER 100 DEGREES ACROSS MUCH OF THE AREA
AND APPROACHING 110 DEGREES ACROSS OUR SOUTHWEST. ENSEMBLE SPREAD
INCREASES BY SATURDAY INTO SUNDAY AS SOME MODELS WANT TO TRY TO
BRING A COLD FRONT INTO/NEAR AND HEAT RELIEF INTO THE AREA, BUT
CONFIDENCE IS RATHER LOW IN THIS SCENARIO AT THIS TIME.
UNFORTUNATELY, WITH THE UPPER RIDGE DOMINATING THE REGION
PRECIPITATION CHANCES WILL REMAIN NEAR ZERO FOR AT LEAST THE NEXT
7 DAYS IF NOT LONGER.

VERY STRONG NORTHWEST WINDS WITH OCCASIONAL GUSTS TO 50 KNOTS WILL
CONTINUE THROUGH THE AFTERNOON AT MOST SITES. THE WIND WILL
DIMINISH SOME THIS EVENING, BUT WILL REMAIN GUSTY 30 TO 35 MPH
