DISCUSSION
(TODAY THROUGH MONDAY)
ISSUED AT 1212 AM CDT TUE APR 7 2026
LITTLE CHANGE IN OVERALL PROGRESSION OF THE FORECAST TONIGHT. DRY
CONDITIONS WITH PLEASANT LEVELS OF HUMIDITY WILL MAINTAIN THROUGH
AT LEAST WEDNESDAY AS EAST WINDS KEEP GULF MOISTURE FROM COMING
BACK INLAND TOO QUICKLY.
A COMPACT, FAST MOVING LOW PRESSURE SYSTEM DRIVES ACROSS THE SOUTH
CENTRAL CANADIAN PROVINCES ON WEDNESDAY, DEFLECTING SFC HIGH
TOWARDS THE EASTERN SEABOARD. TO RESULT, A RETURN OF GULF FLOW AND
FALLING HEIGHTS WHICH MAY ALLOW FOR SOME RETURN OF DIURNAL RAIN
CHANCES BY THE END OF THE WEEK. MOISTURE RETURN WILL NEED TO AMP
UP FOR ANY SHOWERS/STORMS TO OFFER ANY MEANINGFUL RAINFALL,
THOUGH.
AS FOR NOW, ENJOY THE ANOMALOUSLY COOL AND PLEASANT SPRING WEATHER
AS LONG AS IT LASTS THIS WEEK!

AVIATION
(06Z TAFS)
ISSUED AT 1212 AM CDT TUE APR 7 2026
VFR CONDITIONS AND LIGHTLY BREEZY NORTHEAST WINDS WILL PREVAIL
OVER THE PERIOD. DRY AIR AND HIGH PRESSURE INFLUENCE WILL CAUSE
THIS SETUP TO PREVAIL OVER THE COMING DAYS.
DAYTIME HOURS TOMORROW COULD SEE OCCASIONAL GUSTS OF 15 TO 20
KNOTS.
11/CALHOUN
MARINE
ISSUED AT 1212 AM CDT TUE APR 7 2026
EASTERLY WINDS ARE PREVAILING AND WILL MAINTAIN THROUGH THE REST
OF THE FORECAST PERIOD. WINDS WILL BE OCCASIONALLY MODERATE AT
TIMES ON A PRESSURE GRADIENT BETWEEN SURFACE HIGH OVER THE EAST US
AND GULF AIRMASS. THIS LONG FETCH WILL CAUSE A BUILDING OF SEAS
FROM TODAY THROUGH THE REMAINDER OF THE WEEK. THE CORRIDOR OF
GREATEST SEAS SHOULD SET UP ACROSS THE NORTH CENTRAL GULF WITH A
GRADUAL DECREASE IN HEIGHTS FROM THE MOUTH OF THE MISSISSIPPI TO
SABINE PASS. HOWEVER, HAZARDOUS SEA CONDITIONS CAN BE EXPECTED
TO REACH AS FAR WEST AS INTRACOASTAL CITY.
COASTAL AREAS MAY ALSO SEE A SMALL RISE IN WATER LEVELS LATER IN
THE WEEK, BUT COASTAL FLOODING IS NOT ANTICIPATED AT THIS TIME.
FIRE WEATHER
ISSUED AT 1212 AM CDT TUE APR 7 2026
ANOMALOUSLY DRY AND COOL CONDITIONS WILL CONTINUE THROUGH AT LEAST
WEDNESDAY WHEN GULF MOISTURE CAN START MOVING BACK INLAND.
DAYTIME MINIMUM RH VALUES ON TUESDAY ARE FORECAST IN THE 20 TO 30
PERCENT RANGE ONCE AGAIN, HOWEVER, WITH LOWER DAYTIME WINDS, FIRE
CONDITIONS SHOULD NOT BE AS PREVALENT.
MOISTURE RETURNS LATER IN THE WEEK AND WITH DECREASING HIGH
PRESSURE INFLUENCE, VERY LOW RAIN CHANCES TRY TO RETURN TO COASTAL
AREAS. NO NOTABLE OR MEANINGFUL RAIN TOTALS ARE ANTICIPATED
THROUGH THE REST OF THE WEEK.
