SHORT TERM
(THIS AFTERNOON THROUGH SUNDAY NIGHT)
ISSUED AT 1123 AM CDT SAT AUG 15 2026
LATEST 16Z OBS IN THE MID LEVELS SHOWS 2 NOTABLE PERTURBATIONS
WITHIN THE WESTERN PERIPHERY OF THE MAIN ANTI-CYCLONIC FEATURE.
THE FIRST IS MOVING ENE ACROSS WESTERN NM AND THE SECOND IN MOVING
NNW JUST PAST THE RIO GRANDE RIVER. MAIN AREAS OF LIFT OUT AHEAD
OF BOTH PERTURBATIONS, COUPLED WITH CONVECTIVE TEMPS OF MID TO
UPPER 90S TO LIKELY BE ACHIEVED, AREAS OF SHOWERS AND
THUNDERSTORMS ALONG THE EASTERN NM PLAINS EXPANDING EAST INTO THE
WESTERN PANHANDLES IS EXPECTED. SOME OF THE LATEST CAM AND HI-RES
DATA ALSO ARE PICKING UP ON A RELATIVELY WEAK SFC CONVERGENCE
BOUNDARY SETTING UP JUST ALONG AND NORTH OF THE CANADIAN RIVER
FROM ROUGHLY ADRIAN TO CHANNING TO DUMAS TO WAKA. THIS SECONDARY
AREA OF CONVERGENCE COULD ALSO GENERATE SOME STORMS DURING PEAK
HEATING OF THE DAY. SOME OF THESE THUNDERSTORMS COULD BE STRONG TO
SEVERE IN INTENSITY, ESPECIALLY EARLY ON. NOTABLE UP-DRAFTS IN A
RATHER ANEMIC EFFECTIVE SHEAR ENVIRONMENT THAT IS MORE DISCRETE
COULD SUPPORT SOME LARGE HAIL UP TO 1-1.25", ESPECIALLY FOR THE
WESTERN PANHANDLES. AS WE CONTINUE INTO THE EVENING HOURS,
DAMAGING WIND THREAT WILL BE MORE PROBABLE AS MULTI-CELL STORM
MODE AND/OR FORWARD PROPAGATING OUTFLOW/COLD POOLS SHOULD BE THE
MAIN STORM MODE. ALONG WITH SEVERE WIND AND HAIL HAZARDS, SLOW
MOVING AND/OR TRAINING STORMS IN A PWAT ENVIRONMENT OF 75-99TH
PERCENTILE, CANNOT RULE OUT LOCALIZED FLASH FLOODING. RESIDUAL
SHOWERS AND LOW TOPPED STORMS COULD TRICKLE INTO THE EARLY
PORTIONS OF THE OVERNIGHT PERIOD BEFORE CONDITIONS IMPROVE. HIGH
TEMPERATURES THIS AFTERNOON LIKELY TO STILL RANGE FROM THE MID 90S
TO 105 IN PDC, WHERE A HEAT ADVISORY IS IN EFFECT THIS AFTERNOON.
POTENTIAL RINSE AND REPEAT FOUR SUNDAY, FAVORING THE NORTHERN
PANHANDLES ONCE AGAIN FOR DIURNALLY DRIVEN SHOWER AND STORMS,
WHERE WE CANNOT RULE OUT A STRONG TO SEVERE STORMS. BUT THIS TIME,
THE ACTIVITY HIGH TEMPERATURES TOMORROW WILL RANGE FROM THE MID
80S IN THE NW TO UPPER 90S TO NEAR 100 IN THE SE.
LONG TERM
(MONDAY THROUGH NEXT FRIDAY)
ISSUED AT 1123 AM CDT SAT AUG 15 2026
NOT MUCH OF AN EXACT ACCORD BETWEEN THE LATEST GLOBAL MODEL
GUIDANCE FOR THE LONG TERM FORECAST PERIOD. THE SLIGHT MAJORITY
HAS THE MAIN H500 HIGH AND ITS CENTER BUILDING OVER THE PANHANDLES
BY MID WEEK DRYING OUT. POTENTIAL FOR OTHER MID LEVEL DISTURBANCES
GRAZING THE NORTHERN PANHANDLES WITH RAIN CHANCES TOWARDS THE END
OF THE FORECAST PERIOD, BUT CONFIDENCE REMAIN LOW FOR RAIN
CHANCES AT THIS TIME. HIGH TEMPERATURES CONTINUE TO BE ABOVE
AVERAGE AS WE GO PAST MID AUGUST.
AVIATION
(12Z TAFS)
ISSUED AT 620 AM CDT SAT AUG 15 2026
SCATTERED STORMS ARE EXPECTED IN THE VICINITY OF KGUY AND KDHT
THIS EVENING, POSSIBLY LINGERING INTO THE OVERNIGHT HOURS, SO
PROB30 GROUPS ARE INCLUDED AT BOTH SITES. ANY STORMS COULD PRODUCE
STRONG WIND GUSTS GREATER THAN 40 KTS. PREVAILING WINDS WILL BE
PRIMARILY OUT OF THE SOUTH TODAY AT 10-15 KTS, BUT BREEZIER GUSTS
UP TO 25 KTS COULD OCCUR AT KAMA. WINDS WILL BECOME MORE LIGHT AND
VARIABLE BEHIND A BOUNDARY OVERNIGHT, BUT COULD OCCASIONALLY
SETTLE OUT OF THE NORTH AT TIMES.
