VERY LITTLE CHANGE FROM YESTERDAY TO TODAY. HIGH PRESSURE RIDGING
REMAINS IN PLACE OVERTOP THE NORTHWEST GULF, REALLY WORKING TO
OVERHEAT THIS ANOMALOUSLY MOIST AIRMASS ALSO STILL PRESENT FOR ITS
LATE SPRING VISIT. 18Z RAOB REPORTS A PWAT OF 1.85 INCHES WHICH IS
RIGHT AT THE 90TH PERCENTILE... TEMP OF 88 OVER A DEWPOINT OF 73,
THE REAL FEEL OUTDOORS IS ROUGHLY 96F. THE LONG AND SHORT OF THE
FORECAST, PLEASE BE MINDFUL OF HEAT'S AFFECT ON THE BODY IF YOU'RE
OUTDOORS FOR EXTENDED PERIODS.
APPEARS THE RIDGE WILL HANG ON A BIT LONGER INTO MONDAY, CAUSING
THE PREVIOUSLY SCATTERED POPS TO NOW SIT IN THE ISOLATED CATEGORY.
ONLY A FEW SEABREEZE SHOWERS/STORMS MAY BE POSSIBLE IN THE
AFTERNOON HOURS, AND PROBABLY WILL ONLY SEE THESE IN VERY COASTAL
AREAS.
UPPER SHORTWAVE SHOULD BEGIN ITS MOVE DOWN THE EASTERN SEABOARD
INTO TUESDAY, USHERING SOUTHWARD A WEAK BOUNDARY WHICH SHOULD
ARRIVE ON WEDNESDAY. IN THE MEANTIME, WITH WEAKNESS DEVELOPING
OVERHEAD ON TUESDAY, A MORE WIDESPREAD COVERAGE OF DAYTIME
CONVECTION SHOULD BE EXPECTED DURING AFTERNOON HOURS. BY WEDNESDAY
AND BEYOND, INCREASED RAIN CHANCES AND CLOUD COVER SHOULD HELP
BRING A BREAK IN THE HEAT.

DRY AND MUNDANE CONDITIONS TO PERSIST FOR MOST OF THIS FORECAST
PERIOD. THANKS TO THE HIGH MOISTURE CONTENT, WE COULD SEE SOME
PATCHY GROUND FOG AGAIN TONIGHT, HOWEVER DENSE FOG IS NOT EXPECTED
AT THIS TIME. TOMORROW AFTERNOON, WE COULD SEE SOME ISOLATED TO
SCATTERED SHOWERS AT OR IN THE VICINITY OF THE SOUTHERN TERMINALS.
MARINE
ISSUED AT 1245 PM CDT SUN MAY 31 2026
RIDGING WILL REMAIN OVER GULF WATERS TO BRING ABOUT LIGHT TO
OCCASIONALLY MODERATE ONSHORE WINDS, LOW SEAS AND NEARSHORE
DIURNAL SHOWERS. TOWARDS THE MIDWEEK, UPPER LOW PRESSURE WILL
PLACE A WEAK BOUNDARY NEAR THE NORTH GULF COASTLINE, INCREASING
RAIN CHANCES AND SEAS ON INCREASING PRESSURE GRADIENT. WINDS WILL
TURN TO THE EAST AND SEAS INCREASE LATE IN THE WORK WEEK IN
RESPONSE TO THIS BOUNDARY AND TO HIGH PRESSURE DEVELOPING OVER THE
SOUTHEAST US.
FIRE WEATHER
ISSUED AT 1245 PM CDT SUN MAY 31 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.
