UPDATE

OVER EASTERN NEW MEXICO AND ARE MOVING EAST TOWARDS THE TEXAS AND
OKLAHOMA PANHANDLES. FORECAST RAIN CHANCES HAVE BEEN UPDATED
THROUGH THE MORNING BASED ON OBSERVATIONS AND LATEST HI-RES

KEY MESSAGES

BEFORE A POSSIBLE DRYING PERIOD.
SHORT TERM
(TODAY THROUGH FRIDAY NIGHT)
ISSUED AT 1236 AM CDT THU SEP 18 2025
LINGERING SHOWERS AND STORMS TONIGHT AS WE HAVE ABOUT 500-1000 J/KG
OF MLCAPE LEFT OVER. ENVIRONMENT IS MAINLY ELEVATED OVERNIGHT WITH
LOW CLOUDS LINGERING ACROSS MUCH OF THE PANHANDLES. FURTHER SOUTH
THERE IS SOME OUTFLOW THAT COULD TRIGGER SOME NEW STORMS THROUGH THE
NIGHT. TO THE NORTH, ANOTHER SHORTWAVE PUSH WILL BRING MORE ROUNDS
OF SHOWERS AND STORMS OVERNIGHT TO THE OK PANHANDLE. THESE SHOWERS
MAY LINGER OVERNIGHT INTO THE MID MORNING HOURS. AS THE ATMOSPHERE
STABILIZES MORE FURTHER SOUTH, WE'LL STILL HAVE THE OVERALL BOUNDARY
HOLDING IN PLACE ALONG THE I-40/HWY60 CORRIDOR. THE CHALLENGE WILL
BE IF WE GET ENOUGH HEATING TOMORROW TO TRIGGER MORE
AFTERNOON/EVENING STORMS ALONG THE BOUNDARY, OR IF WE'RE TOO WORKED
OVER AND THOSE MORNING SHOWERS LINGER TOO LONG FOR US TO REHEAT BACK
UP AND DESTABILIZE ENOUGH TO GET STORMS. DETERMINISTIC AND CAMS ARE
AT ODDS, WITH THE CAMS BEING MORE BEARISH ON THE STORMS DEVELOPING.
CURRENT POPS TO REFLECT THE MORE BEARISH SCENARIO FOR THURSDAY.
EITHER WAY, WITH THE FRONT THROUGH AND ALL THE MOISTURE FROM
YESTERDAY AND EARLY TODAY WE'RE LOOKING AT HIGHS IN THE 70S FOR THE
MOST PART, WITH LOWER 80S IN THE SOUTHERN PANHANDLE.
AS WE MOVE INTO FRIDAY THE TROUGH AXIS WILL START TO MOVE EAST INTO
OKLAHOMA AND WE'LL BEGIN TO GET A RIDGE BUILD OVER THE PANHANDLES,
WITH MAINLY WESTERLY FLOW TO START. OVERALL, TEMPERATURES WILL
REBOUND BACK INTO THE MID 80S, AND WITH THE AMPLE MOISTURE THAT
WE'VE RECEIVED AS WELL AS SOME INCREASED MOISTURE MOVING IN FROM NM,
WE COULD GET SOME ISOLATED TO SCATTERED SHOWERS FRIDAY EVENING AND
OVERNIGHT. THE SOUTHWEST PANHANDLES WOULD BE THE MOST FAVORED, BUT
WILL NOT RULE OUT THIS JUST ABOUT ANYWHERE.
WEBER
LONG TERM
(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 1236 AM CDT THU SEP 18 2025
OVERALL FOR THE EXTENDED WE WILL BE IN A TRANSITION PERIOD AS THE
RIDGE ATTEMPTS TO REBUILD OVER THE SOUTH CENTRAL CONUS. THIS STILL
WILL NOT BE WITHOUT CHALLENGES AS SUBTLE WAVES IN THE WEST TO
NORTHWEST FLOW CONTINUE TO PUSH ACROSS THE PANHANDLES AND COULD
TRIGGER SOME AFTERNOON SHOWERS AND STORMS. AS WE MOVE INTO MID NEXT
WEEK, IT DOES APPEAR THAT WE'LL BE LOOKING AT ANOTHER WEATHER SYSTEM
THAT MAY TRACK JUST NORTH OF OUR AREA, THEN DIVE DOWN SOUTH OVER THE
CENTRAL OK AREA, AND PROVIDE MORE OF A BACKDOOR COLD FRONT. THIS
PATTERN ALSO SUPPORTS MUCH LOWER PROBABILITY OF POPS IN THE
EXTENDED. STILL, WOULD NOT THAT AT LEAST SATURDAY AND SUNDAY HAVE
SOME LEVEL OF STORM CHANCES, ESPECIALLY IN THE EASTERN PANHANDLES.

AVIATION
(06Z TAFS)
ISSUED AT 1236 AM CDT THU SEP 18 2025
MVFR/IFR CONDITIONS TO START AS STORMS ARE APPROACHING THE TAF
SITES. AFTER 12Z THE CHANCES OF STORMS SHOULD DIMINISH, AND WE'LL
STILL HAVE LOW CIGS DUE TO TO CLOUD COVER, BUT WE SHOULD START TO
IMPROVE THE CIGS AROUND THE 12-18Z TIME PERIOD AS WE START TO GO
MORE SCATTERED IN CLOUD COVER. WITH THE FRONT THROUGH FOR THE MOST
PART, WE'RE LOOKING AT VARIABLE WINDS AROUND 5 TO 10KTS.
