UPDATE
ISSUED AT 755 PM CDT THU MAY 29 2025
A CLUSTER OF STORMS DEVELOPED OVER CENTRAL OK AND TRACKED ACROSS
SOUTHEAST OK LATE THIS AFTERNOON, PRIMARILY BEHIND AN ADVANCING
COLD FRONT. ON THE WESTERN END OF THE ACTIVITY, A NEARLY STEADY-
STATE SEVERE STORM HAS TRACKED ACROSS SOUTH-CENTRAL OK AND IS
APPROACHING PUSHMATAHA AND CHOCTAW COUNTIES IN SE OK, INCREASING
THE SEVERE THREAT THERE. AFTER THIS ACTIVITY LEAVES THE AREA, SOME
ADDITIONAL DEVELOPMENT IS EXPECTED NEAR THE RED RIVER LATER
TONIGHT, AND THESE STORMS MAY CLIP PARTS OF FAR SE OK NEAR THE RED
RIVER LATER TONIGHT. RAIN AND THUNDER CHANCES SHOULD EXIT THE
REGION BY 12Z FRIDAY MORNING. CLEARING SKIES, COOLER AND DRIER AIR
MOVING INTO THE REGION BEHIND THE FRONT WILL YIELD OVERNIGHT LOWS
AS MUCH AS 10 DEGREES BELOW AVERAGE FOR THIS TIME OF YEAR IN SPOTS
NORTH OF I-40.
LACY
SHORT TERM
(THROUGH TONIGHT )
ISSUED AT 209 PM CDT THU MAY 29 2025
SURFACE COLD FRONT MAKING STEADY PROGRESS SOUTHEAST THIS AFTERNOON
AND IS CURRENTLY LOCATED NEAR I-44. AIRMASS SOUTH OF THE FRONT
CHARACTERIZED BY MUCAPE IN THE 1500-2500 RANGE WITH DEW POINTS IN
THE MID/UPPER 60S. EXPECT SCATTERED THUNDERSTORMS TO EVENTUALLY
DEVELOP ALONG THE FRONT BY THIS EVENING, WITH A LOW-END THREAT OF
HAIL AND WIND WITH ANY MORE ORGANIZED CELLS. AN UPTICK IN
COVERAGE OF MAINLY ELEVATED STORMS IS POSSIBLE LATE THIS EVENING
ACROSS SOUTHEAST OK AS CONVECTION MOVES ESE OFF THE HIGH PLAINS
WITHING A FRONTAL ZONE ALOFT.
BEHIND THE SURFACE FRONT, ALMOST CHILLY CONDITIONS BY LATE MAY
STANDARDS WITH TEMPS IN THE LOW-MID 60S AND A 10-15 MPH NORTH
WIND. EXPECT TO SEE GRADUALLY CLEARING SKIES OVERNIGHT WITH TEMPS
DROPPING INTO THE 50S IN MOST OF THE AREA, WITH SOME UPPER 40S
POSSIBLE CLOSER TO THE KS AND MO BORDERS IF ENOUGH CLEARING
OCCURS.
LONG TERM
(TOMORROW THROUGH THURSDAY)
ISSUED AT 209 PM CDT THU MAY 29 2025
DRY CONDITIONS WITH CONSIDERABLY MORE SUN THAT WE HAVE SEEN
RECENTLY ARE IN STORE SATURDAY, WITH WARMER AFTERNOON
TEMPERATURES AND RELATIVELY LOW DEW POINTS MAKING FOR A PLEASANT
LATE SPRING DAY. A NOTABLE WARMING TREND BEGINS SATURDAY WITH AT
LEAST MODEST LOW LEVEL MOISTURE RETURN. A COMPACT SHORTWAVE IN
NNW FLOW IS STILL EXPECTED TO DROP INTO THE CENTRAL AND SOUTHERN
PLAINS BY LATE SATURDAY. WHILE THE NBM CONTINUES TO KEEP POPS
BELOW 15% THE PAST SEVERAL RUNS, A NUMBER OF GLOBAL ENSEMBLE
MEMBERS SHOW AT LEAST SOME QPF WITH THIS FEATURE SATURDAY NIGHT OR
EARLY SUNDAY. GIVEN THIS PLUS A TENDENCY FOR SYSTEMS LIKE THIS TO
OVERACHIEVE, WILL KEEP AT LEAST A LOW PROBABILITY OF SHOWERS AND
STORMS FOR SATURDAY NIGHT, THOUGH THE UNCERTAINTY REMAINS HIGH.
ASSUMING THIS WAVE CLEARS THE AREA IN TIME, SUNDAY WILL BE DRY AND
WARM AHEAD OF AN UNSETTLED SOUTHWEST PATTERN DEVELOPING EARLY
NEXT WEEK. BY MONDAY EXPECT TO SEE STORMS DEVELOP WELL TO OUR
WEST, POTENTIALLY MOVING INTO EASTERN OK LATE MONDAY NIGHT.
TUESDAY REMAINS THE PERIOD OF INTEREST FOR OUR AREA WITH A
SHORTWAVE EJECTING OUT OF THE SOUTHWEST BRINGING POSSIBLE UPTICK
IN SEVERE WEATHER POTENTIAL. UNSETTLED PATTERN LOOKS MORE LIKELY
FOR THE REMAINDER OF NEXT WEEK AS WELL, WITH AT LEAST PERIODIC
THREATS OF HEAVY RAINFALL AND SEVERE WEATHER.
