SHORT TERM
(TONIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 1235 PM CDT THU SEP 11 2025
A LARGE DOME OF HIGH PRESSURE RESTS OVER THE SOUTHERN PLAINS TODAY
WHILE GENTLE UPPER LEVEL FLOW USHERS DRY CONTINENTAL AIR FROM THE
NORTH. WINDS IN THIS REGIME ARE EXPECTED TO BE LIGHT WITH VARIABLE
SHIFTS DURING MORNINGS AND EVENINGS DURING LAND / SEA BREEZES. THIS
WILL BE TO A LESSER EFFECT FURTHER INLAND OVER CENLA. GIVEN LOCAL
HIGH PRESSURE ENVIRONMENT, CONDITIONS WILL TREND DRY WITH NO
ORGANIZED PRECIPITATION EXPECTED INTO THE WEEKEND. HIGHS FORECAST TO
RANGE IN THE LOW TO MID 90'S AND LOWS TOWARD 70°F GIVE OR TAKE A FEW
DEGREES.

LONG TERM
(SUNDAY THROUGH NEXT WEDNESDAY)
ISSUED AT 1235 PM CDT THU SEP 11 2025
SUNDAY, THE HIGH PRESSURE PATTERN BUILDS AND EXPANDS ALONG THE
MISSISSIPPI VALLEY KEEPING CONDITIONS DRY AGAIN INTO THE NEW WEEK.
WITH THE SURFACE RIDGING ADJUSTED FURTHER TO OUR NORTH AND EAST,
SOME ONSHORE FLOW MAY PERTURB THE MARINE BOUNDARY LAYER FURTHER
INLAND POTENTIALLY LEADING TO SOME WEAK COASTAL SHOWERS. BLENDED
GUIDANCE, WHILE RECOGNIZING THE COAST TO BE SUSCEPTIBLE TO SEABREEZE
ACTIVITY, HIGHLY LIMITS EVEN ISOLATED CHANCES. THAT BEING SAID, THIS
IS THE ONLY CONFIDENCE CAVEAT TO THE FORECAST, AS MORE SIGNIFICANT
WEATHER WILL BE STEERED AWAY FROM LOCAL AREA INTO THE MIDDLE OF NEXT
WEEK. HIGHS WILL MEANDER BETWEEN THE LOW TO MID 90'S WHILE EVENING
LOWS TREND INTO THE MID 60'S FOR INTERIOR LOCATIONS COMPARED TO THE
COAST WHERE LOW 70'S ARE MOST LIKELY TO MAINTAIN THROUGH THE
REMAINDER OF THE FORECAST PERIOD.

AVIATION
(00Z TAFS)
ISSUED AT 557 PM CDT THU SEP 11 2025
FEW VFR CLOUDS ARE ONGOING OVER THE REGION ALONG WITH SOMEWHAT
BREEZY EAST SOUTHEAST WINDS. OTHERWISE, NOT MUCH GOING ON. HIGH
PRESSURE WILL REMAIN IN CONTROL THROUGH THE PERIODS RESULTING IN
A FAIRLY PERSISTENCE FORECAST. EXPECT CONDITIONS TO REACH CALM AND
CLEAR OVERNIGHT. SOME AREAS OF PATCHY FOG ARE POSSIBLE, BUT
IMPACTS TO TERMINALS ARE UNLIKELY DUE TO THE DRY NATURE OF AIRMASS
OVER THE REGION.
FEW CLOUDS RETURN AFTER SUNRISE AROUND 5 KFT, BECOMING SCATTERED
CUMULUS FIELDS IN THE AFTERNOON. WINDS WILL START OUT
NORTHEASTERLY BEFORE BECOMING MORE SOUTHEASTERLY WITH DIURNAL
PROCESSES TAKING PLACE.
DRY AIRMASS AND HOT TEMPS MAY BRING ABOUT AFTERNOON WIND GUSTS AS
THE AIRMASS MIXES OUT.
11/CALHOUN
MARINE
ISSUED AT 1235 PM CDT THU SEP 11 2025
WINDS WILL GENERALLY RANGE FROM THE NE-SE THROUGHOUT THE FORECAST
PERIOD. HOWEVER, SURFACE HIGH PRESSURE RIDGING INTO THE NORTHWEST
GULF WILL ALLOW LAND / SEABREEZES TO OCCUR AS WELL. HIGHER WINDS
AND SEAS IN THE 20 TO 60 NM WATERS WILL EASE AND ABATE THROUGH
THIS EVENING. FROM TOMORROW MORNING TO AT LEAST EARLY SUNDAY,
THIS BOUNDARY WASHES OUT CREATING HOT AFTERNOONS WITH LOW SEAS
UNDER LIGHT TO GENTLE WINDS.
FIRE WEATHER
ISSUED AT 1235 PM CDT THU SEP 11 2025
HOT AND DRY CONDITIONS WITH BREEZY, VARIABLE WINDS TO BE EXPECTED
THIS EVENING THRU THE START OF NEXT WORK WEEK. HIGH PRESSURE OVER
THE REGION STRENGTHENS FROM FRIDAY THROUGH SUNDAY ALLOWING HIGH
TEMPS TO DRIVE INTO THE MID TO UPPER 90S EACH DAY. SURFACE MIXING IS
EXPECTED EACH AFTERNOON WITH DAYTIME RH MINIMUMS IN THE 30 TO 45
PERCENT RANGE.
