KEY MESSAGES
ISSUED AT 134 PM CDT SAT MAR 21 2026

FRONT MOVES THROUGH THE REGION.

WEATHER WILL RETURN TUESDAY THROUGH MOST OF NEXT WEEK.
SHORT TERM
(THIS EVENING THROUGH SUNDAY)
ISSUED AT 134 PM CDT SAT MAR 21 2026
IT'S THE SAME TUNE, DIFFERENT DAY. THE UPPER HIGH REMAINS OVER THE
DESERT SOUTHWEST. THE UPPER HIGH HAS MOVED JUST SLIGHTLY EAST FROM
IT'S PREVIOUS POSITION ON FRIDAY. THIS IS ALLOWING FOR THE WARMER
TEMPERATURES EXPECTED THIS AFTERNOON, MID/UPPER 90S ON THE CAPROCK
AND AROUND 100 ACROSS THE ROLLING PLAINS. A SURFACE LEE TROUGH IS
SLOWLY BEGINNING TO DEVELOP PER SURFACE OBS. DESPITE THIS, WE SHOULD
ONLY SEE WINDS TOP OUT AROUND 10-15 MPH THIS AFTERNOON WITH A FEW
GUSTS TO 20 POSSIBLE AS THE SURFACE PRESSURE GRADIENT REMAINS
RELAXED. THE UPPER HIGH WILL BEGIN TO FLATTEN THIS EVENING THROUGH
TONIGHT. DURING THIS SAME TIME A COLD FRONT WILL PUSH SOUTHWARD FROM
THE NORTHERN PLAINS AND IS PROGGED TO REACH OUR NORTHERN ZONES BY
NOON SUNDAY. BREEZY CONDITIONS ARE EXPECTED BEHIND THE COLD FRONT
WITH SUSTAINED WINDS BEING JUST BELOW ADVISORY CRITERIA. DESPITE
RELATIVE HUMIDITY INCREASING TO 20 PERCENT OR HIGHER BEHIND THE COLD
FRONT, STRONGER WINDS WILL CREATE CRITICAL FIRE WEATHER DANGER AS
FUELS WILL ALREADY BE EXTREMELY DRY AND WILL BE SLOW TO RESPOND TO
THE INCREASE IN HUMIDITY. WHILE TEMPERATURES WILL BE NOTICEABLY
COOLER BEHIND THE FRONT, HIGH TEMPS WILL STILL LIKELY REACH INTO THE
MID/UPPER 90S ON THE CAPROCK AND AROUND 100 ACROSS THE ROLLING
PLAINS.
LONG TERM
(SUNDAY NIGHT THROUGH NEXT FRIDAY)
ISSUED AT 134 PM CDT SAT MAR 21 2026
MONDAY WILL BE AN AVERAGE OF 20-25 DEGREES COOLER THAN SUNDAY THANKS
TO THE COLD FRONT. COOLER TEMPERATURES WILL BE SHORT LIVED, HOWEVER,
AS THE UPPER HIGH IS EXPECTED TO BUILD ONCE AGAIN BY TUESDAY JUST AS
SURFACE WINDS VEER TO THE SOUTH. THE UPPER HIGH WILL MOVE EASTWARD
THROUGH MID-WEEK AND EVENTUALLY SETTLE OVER THE SOUTHERN PLAINS.
WHILE THIS WILL WARM HIGHS BACK INTO THE 90S, WE SHOULD AVOID HIGHS
NEAR 100 AS THE HIGH WILL BE WEAKER THAN THE CURRENT UPPER HIGH,
H588 VS H594. EVEN THIS WARM UP SHOULD ONLY LAST THROUGH THE END OF
THE WEEK. MODELS HAVE BEEN IN FAIRLY DECENT AGREEMENT WITH BRINGING
ANOTHER COLD FRONT INTO THE REGION BY LATE FRIDAY/EARLY MONDAY. THIS
FRONT WILL ALSO BE DRY WITH NO PRECIP.
AVIATION
(18Z TAFS)
ISSUED AT 1236 PM CDT SAT MAR 21 2026
VFR WILL PERSIST THIS TAF CYCLE. A 40-50 KNOT SOUTHWESTERLY LLJ WILL
DEVELOP OVERNIGHT, LEADING TO PERIODS OF LLWS. A COLD FRONT WILL
BRING A NORTHERLY WIND SHIFT TO THE TERMINALS AROUND MIDDAY SUNDAY.
OTHERWISE, GIVEN THE UNSEASONABLE HEAT, BE SURE TO CHECK THE DENSITY
ALTITUDE.
