DISCUSSION

WX MAP FEATURES A LARGE HIGH PRESSURE CELL OVER THE CANADIAN / US
BORDER TODAY. MODEST RIDGING EXTENDS ACROSS THE CENTRAL PLAINS TO
THE GULF COAST KEEPING CONDITIONS HERE LOCALLY DRY AND MILD. HIGHS
WILL RANGE IN THE LOWER 80S WITH MOSTLY CLEAR SKIES- SANS A FEW
UPPER LEVEL CLOUD FROM MOISTURE WICKED UP FROM THE EASTERN PACIFIC.
OTHER THAN THAT WE ARE EXPECTING CHAMBERS OF COMMERCE WEATHER,
QUIET, SUNNY, AND PLEASANTLY NOT HUMID. HOWEVER, THE LACK OF
RAINFALL WILL PROVE TO BE PROBLEMATIC OVER THE NEXT SEVERAL DAYS
CONCERNING THE WORSENING DROUGHT AND FIRE WEATHER CONCERNS.
TEMPERATURES DO RISE THURSDAY AND FRIDAY AS A SUBTROPICAL RIDGE
STRENGTHENS THE SURFACE RIDGE EXTENDING SOUTH FROM CANADA. INCREASED
SUBSIDENCE ALOFT WILL PROMOTE HIGHS IN THE MID 80S WITH ZERO CHANCE
FOR RAINFALL. THIS PATTERN WILL ALSO KEEP WINDS LIGHT WITH PERIODS
OF NORTHEAST TO EAST BREEZES. THE RIDGE CONTINUES TO AMPLIFY THROUGH
THE WEEKEND CREATING AN OMEGA BLOCK ACROSS THE CONUS. THIS TYPE OF
PATTERN GENERALLY FAVORS PORTIONS OF THE CONTINENT TO HAVE MORE
RAINFALL WHILE OTHER AREAS OBSERVE LESS. SINCE SOUTHEAST TEXAS AND
SOUTHWEST LOUISIANA WILL BE IN THE CENTER AXIS OF THE RIDGE, THE
FORECAST WILL STAY DRY HERE INTO NEXT WEEK WHILE HIGHS RETURN CLOSE
TO NORMAL, IN THE LOW 80S. MORNINGS WILL FEEL NICE FOR THOSE WHO
ENJOY A CRISP EARLY WORKOUT. THOSE LOW TEMPERATURES OCCURRING AROUND
6-7AM WILL RANGE IN UPPER 40S ACROSS CENTRAL PORTIONS OF LOUISIANA
AND INTERIOR SOUTHEAST TEXAS TO MID OR UPPER 50S FOR THE COASTAL
COUNTIES AND PARISHES.

MARINE
ISSUED AT 1201 AM CDT WED OCT 21 2026
GENTLE TO MODERATE EAST WINDS CONTINUE ACROSS THE OFFSHORE GULF
WATERS THIS AFTERNOON INTO EVENING AS A WAVE MOVES WESTWARD ACROSS
THE CENTRAL GULF. WINDS OF 10-15 KT AND SEAS 2-4 FEET WILL BE
POSSIBLE. THEREAFTER, HIGH PRESSURE OVER THE EASTERN US WILL YIELD
EAST TO NORTHEAST WINDS AT 5-15 KT WITH LOW SEAS THROUGH THE WEEKEND
AND INTO NEXT WEEK.
FIRE WEATHER
ISSUED AT 1201 AM CDT WED OCT 21 2026
AN OMEGA BLOCK PATTERN WITH A BUILDING RIDGE OVER THE SOUTH-CENTRAL
US WILL KEEP DRY CONDITIONS IN PLACE OVER THE CWA THROUGH THE
WEEKEND AND INTO NEXT WEEK. AFTERNOON HIGHS WILL BE ON A SLIGHT
WARMING TREND, WITH NO REAL INCREASE IN MOISTURE EXPECTED, WHICH
WILL ALLOW RH TO FALL TO THE 25 TO 35 PERCENT RANGE EACH AFTERNOON.
ALTHOUGH WINDS WILL REMAIN LIGHT THROUGH THE FORECAST PERIOD, OUT OF
THE EAST AT AROUND 5-10 MPH, FIRE DANGER IS LIKELY TO BE ELEVATED
EACH AFTERNOON WITH THE COMBINATION OF THE DRY AIRMASS AND VERY DRY
FUELS DUE TO ONGOING DROUGHT.
