DISCUSSION
(THIS EVENING THROUGH NEXT FRIDAY)
ISSUED AT 128 PM CDT SAT MAY 30 2026
A MUCH MORE QUIET FORECAST IS IN STORE COMPARED TO THIS TIME LAST
WEEK. LATEST SATELLITE IMAGERY AND RAP ANALYSIS INDICATE HIGH
PRESSURE RIDGING OVER THE REGION, NEARLY PERFECTLY CENTERED DOWN
THE SABINE RIVER. THIS HAS BROUGHT ABOUT WIDESPREAD DRY WEATHER,
VERY WARM TEMPERATURES AND FAIR-WEATHER CUMULUS. WITH SUCH WARM
TEMPS COMBINED WITH THE ANOMALOUSLY MOIST AIRMASS, THE REAL-FEEL
OUT THERE HAS CREPT INTO THE MID TO UPPER 90S! IT'S SHAPED UP TO
BE A RATHER STEAMY WEEKEND!
VERY LITTLE CHANGE CAN BE EXPECTED FOR OUR SUNDAY WITH THE SAME
PATTERN IN PLACE. IN FACT, TEMPS MAY EVEN CREEP UP BY A DEGREE OR
SO BRINGING AN EVEN-WARMER FEELING DAY.
HIGH PRESSURE BACKS OFF A BIT INTO MONDAY, ERODED BY UPPER WAVE
MOVING ACROSS THE UPPER PLAINS STATES. THIS SHOULD ALLOW FOR A
WEAK BOUNDARY TO DROP INTO THE EAST GULF STATES ON ANOTHER
SHORTWAVE CURRENTLY SITUATED NEAR NEW ENGLAND. THIS BOUNDARY,
COMBINED WITH SOUTHERN ROUTE OF THE AFOREMENTIONED NE SHORTWAVE, WILL
BLOCK RIDGING FROM RETURNING. THUS, A RETURN TO DIURNAL RAIN
CHANCES (SEABREEZE INCLUDED!) CAN BE ANTICIPATED FOR AT LEAST THE
FIRST PART OF THE WORK WEEK.
RIDGING WILL REMAIN IN PLACE OVER MUCH OF TEXAS. ITS INFLUENCE
WILL STILL BE FELT IN THE VERY INTERIOR PORTIONS OF DEEP SOUTHEAST
TEXAS AND CENLA AS TEMPS CLIMB BY A DEGREE OR SO EACH DAY. AS WE
MOVE INTO THIS "HEAT WAVE" IT'S INCREDIBLY IMPORTANT TO DUST OFF THOSE
BEST PRACTICES FOR HOT AND HUMID WEATHER. MAKE SURE TO FUEL YOUR
BODY PROPERLY WITH FOOD AND HYDRATION, TAKE FREQUENT BREAKS, AND
ALSO KEEP AN EYE ON EACH OTHER!
CLOUD COVER AND SLIGHTLY HIGHER RAIN CHANCES RETURN TO THE
FORECAST TOWARDS THE MIDDLE-END OF THE WEEK WITH HIGHS BACK IN THE
UPPER 80S ONCE AGAIN. HOLD IN THERE!

AVIATION
(18Z TAFS)
ISSUED AT 128 PM CDT SAT MAY 30 2026
LOW, FAIR WEATHER CUMULUS CLOUDS WILL HANG AROUND THROUGH SUNDOWN.
OVERNIGHT, SOME AREAS OF PATCHY FOG MAY DEVELOP, BUT WIDESPREAD
DENSE FOG IS NOT ANTICIPATED. MENTIONS DOWN TO 4 AND 5 SM WAS
INCLUDED AT MOST WEST AND INLAND TERMINALS. LOWER CONFIDENCE IN
FOG AT LOWER ACADIANA AT THIS TIME.
OTHERWISE, WINDS WILL REMAIN PRIMARILY LIGHT AND VARIABLE FROM THE
SOUTH OVER THE PERIOD BENEATH RIDGING ALOFT.

MARINE
ISSUED AT 128 PM CDT SAT MAY 30 2026
RIDGING INFLUENCE OVER THE NORTH GULF WILL KEEP WINDS FROM THE
SOUTH AND LIGHT OVER THE PERIOD. SEAS WILL ALSO REMAIN RELATIVELY
LOW UNDERNEATH THIS HIGH PRESSURE RIDGE.
RIDGING BACKS DOWN FOR A BRIEF PERIOD TOWARDS THE START OF THE
WORK WEEK RESULTING IN THE RETURN OF SOME MARINE / SEABREEZE
CONVECTION MONDAY AND TUESDAY.
FIRE WEATHER
ISSUED AT 128 PM CDT SAT MAY 30 2026
RIDGING SETTLED OVER THE REGION IS RESULTING IN DRY WEATHER
ONGOING. WHILE THERE REMAINS AN ANOMALOUSLY MOIST AIRMASS ALSO SET
INTO THE NORTH GULF, DRY CONDITIONS FROM HIGH PRESSURE ARE
ALLOWING DAYTIME RH VALUES TO MIX DOWN TO THE 45 TO 60 PERCENT
RANGE.
A SLIGHT WEAKNESS IN HIGH PRESSURE WILL DEVELOP AT THE START OF
THE WORK WEEK ALLOWING FOR A WEAK BOUNDARY TO MOVE INTO THE
REGION. THIS BOUNDARY WILL THEN BECOME THE FOCUS FOR MORE
DIURNALLY DRIVEN, SEABREEZE, RAIN CHANCES TO RETURN TO THE
FORECAST.
