DISCUSSION
(TODAY THROUGH TUESDAY)
ISSUED AT 1233 AM CDT WED APR 8 2026
TEMPERATURES MODERATED AGAIN TODAY WITH HIGHS IN THE MID TO UPPER
70S AREAWIDE. STARTING TODAY/WEDNESDAY, IT'LL PROGRESSIVELY FEEL
WORSE OUTSIDE AS A WARMING TREND DEVELOPS AND AS MOISTURE FILTERS
BACK ONSHORE. HIGH PRESSURE WHICH HAS LARGELY KEPT US DRY WILL SHIFT
EAST TODAY TOWARDS THE EASTERN SEABOARD. THIS SHIFT WILL NUDGE
SFC WINDS INTO A SOUTHEAST VECTOR AND SO THE DOOR OPENS FOR GULF
MOISTURE RETURN OVER THE REST OF THE WEEK.
SOME RAIN CHANCES WILL CREEP BACK INTO THE FORECAST FOR AREAS PRETTY
MUCH ALONG AND SOUTH OF HWY 190 TODAY THROUGH THE EARLY WEEKEND. A
SERIES OF VERY WEAK UPPER LEVEL WAVES WILL PASS FROM LATE THURSDAY
INTO SATURDAY, HELPING TO GENERATE SOME VERY MINOR LIFT. BUT EVEN
WITH INCREASING LOW LEVEL HUMIDITY, MODERATE MIDLEVEL RIDGING AND
DEEP DRY AIR ALOFT WILL LIMIT MUCH CONVECTIVE DEVELOPMENT. BEST
CHANCES ARE IN COASTAL AREAS AND ACROSS SOUTHEAST TEXAS, THE
REGION FURTHEST FROM RIDGING. ANY SHOWERS AND STORMS THAT DO
DEVELOP WILL BE ISOLATED TO VERY WIDELY SCATTERED AND LIKELY WON'T
AMOUNT TO MUCH FOR RAINFALL TOTALS SINCE PWATS LOOK TO REMAIN SHY
OF 1.00 INCHES.
SFC RIDGING SETS IN FOR THE REST OF THE WEEKEND STAUNCHING RAIN
CHANCES AND MAKING FOR STIFLING CONDITIONS.
THE NEXT WEATHER SYSTEM BEGINS TAKING SHAPE INTO THE START OF NEXT
WORK WEEK WHICH COULD BRING THE NEXT MENTIONABLE CHANCE OF RAINFALL
TO THE REGION.

AVIATION
(06Z TAFS)
ISSUED AT 1233 AM CDT WED APR 8 2026
WINDS WILL TAKE ON A MORE SOUTHEASTERLY COMPONENT OVER THE PERIOD AS
HIGH PRESSURE DOMINATING THE WEATHER PATTERN SHIFTS INTO THE EASTERN
SEABOARD. THIS GULF-ORIENTED VECTOR WILL OPEN THE DOOR FOR MOISTURE
RETURN, AND WITH IT, INCREASING CLOUD COVER IN THE LOW LEVELS.
SCATTERED FAIR-WEATHER TYPE CU FIELDS IN THE 3 TO 5 KFT RANGE CAN BE
EXPECTED DURING AFTERNOON HOURS TODAY.
THERE IS A VERY LOW END CHANCE OF AN ISOLATED SHOWER THIS AFTERNOON
FOR EXTREME COASTAL AREAS AS MOISTURE COMES ONSHORE.
WINDS WILL START THE PERIOD PREVAILING FROM THE NORTHEAST BEFORE
SHIFTING TO THE EAST AND THEN SOUTHEAST FROM SUNRISE TO EARLY
AFTERNOON. SPEEDS INCREASE WITH DAYTIME HEATING AND WILL PREVAIL 10
TO 15 KNOTS. SCATTERED INSTANCES OF VARIABLE WIND GUSTS ARE ALSO
LIKELY DUE TO DIURNAL MIXING.
MARINE
ISSUED AT 1233 AM CDT WED APR 8 2026
HIGH PRESSURE WHICH HAS BEEN DOMINATING THE FORECAST WILL SHIFT
TOWARDS THE EASTERN SEABOARD TODAY. THIS TYPICALLY RESULTS IN A
DIRECT TURN TO ONSHORE WINDS, HOWEVER, A BOUNDARY SITUATED IN THE
SOUTH GULF WILL KEEP PRESSURE FIELDS OVER THE WATERS TIGHT AND IN A
WEST TO EAST ORIENTATION TO THE COAST. STRONG EASTERLY WINDS WILL
PERSIST THROUGH THE NEXT DAYS AS THIS PATTERN PERSISTS. SEAS WILL
CONTINUE BUILDING AND SHOULD REACH THEIR MAXIMUM HEIGHTS ON THURSDAY.
CONDITIONS WILL BEGIN IMPROVING THERE AFTER AS HIGH PRESSURE BUILDS
IN ONCEMORE.
FIRE WEATHER
ISSUED AT 1233 AM CDT WED APR 8 2026
HIGH PRESSURE SHIFTS INTO THE EASTERN SEABOARD STARTING TODAY,
ALLOWING WINDS TO GENERALLY TURN TOWARDS THE EAST-SOUTHEAST AND FOR
MOISTURE TO BEGIN RETURNING TO THE REGION. DAYTIME RH VALUES WILL
VARY IN THE 30 TO 40 PERCENT RANGE TODAY, 40 TO 50 THURSDAY, AND 40
TO 60 ON FRIDAY.
THE PRIMARY WIND DIRECTION THROUGH THE REST OF THE WEEK WILL BE EAST-
SOUTHEAST. DURING DAYTIME HOURS WHEN MIXING TAKES PLACE, THERE
COULD BE SOME VARIANCE IN DIRECTIONS AT TIMES. DAYTIME 20 FT SPEEDS
WILL BE SUSTAINED AT AROUND 5 TO 13 KNOTS EACH DAY.
HIGHER TRANSPORT SPEEDS CAN BE FOUND CLOSER TO THE COASTLINE.
