AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1229 PM CDT SUN APR 12 2026
..NEW UPDATE, AVIATION
KEY MESSAGES
- A FRONTAL BOUNDARY WILL STALL NW OF THE REGION TODAY PROVIDING A
FOCUS FOR A SHOWERS AND THUNDERSTORMS TO DEVELOP ACROSS SETX AND
POSSIBLY GETTING INTO WESTERN PORTIONS OF LOUISIANA OVERNIGHT.
- TEMPERATURES WILL CLIMB INTO THE MID TO UPPER 80S FOR A MAJORITY
OF THE AREA, WITH SOME LOW 90S POSSIBLE.
UPDATE
ISSUED AT 1223 PM CDT SUN APR 12 2026
WHILE LOOKING AT THE FORECAST FOR THE AVIATION FORECAST DID
REQUIRE AN UPDATE AS IT APPEARS THE MAIN CONVECTIVE COMPLEX WILL
WEAKEN FASTER THAN INDICATED EARLIER. THIS DID MUTE THE CHANCES A
BIT MAINLY FOR LOUISIANA. STILL LOOKS LIKE PORTIONS OF TYLER,
HARDIN AND JASPER COULD SEE SOME BENEFICIAL RAINS OUT OF IT.
DISCUSSION
(TODAY THROUGH SATURDAY)
ISSUED AT 1241 AM CDT SUN APR 12 2026
AT THE SURFACE, HIGH PRESSURE OFF TO THE EAST WILL MAINTAIN
SOUTHERLY FLOW FOR NEARLY THE ENTIRE DURATION OF THIS FORECAST
PERIOD. THERE IS A BIT OF A TIGHTENED PRESSURE GRADIENT, HENCE THE
ELEVATED FLOW; HOWEVER WINDS ARE EXPECTED TO STAY BELOW WIND
ADVISORY CRITERIA. A BOUNDARY WILL PUSH INTO CTRL TX OVER THE DAY
BEFORE STALLING OUT AND WEAKENING. PARTS OF OUR SETX COUNTIES COULD
SEE SOME ISOLATED TO SCATTERED SHOWERS AS A RESULT. FROM THERE
THROUGH THE REST OF THE WORK WEEK, RAIN CHANCES ARE PRACTICALLY NIL.
ALOFT, AN UPPER LEVEL HIGH PRESSURE WILL ASSIST IN KEEPING THE AREA
NEARLY RAIN FREE AND PLENTY WARM. TODAY THROUGH THE FIRST FEW DAYS
OF THE WORK WEEK, TEMPERATURES WILL BE IN THE LOWER TO MID 80S, WITH
MID TO UPPER 80S (AND POSSIBLY LOW 90S) IN STORE FROM THE MID WEEK
PERIOD. OVERNIGHT CONDITIONS WILL BE WARM AND HUMID, WITH LOW TEMPS
FORECAST TO GENERALLY BE IN THE MID TO UPPER 60S. THROUGH THE WEEK,
LIGHT GROUND FOG WILL BE POSSIBLE OVERNIGHT INTO THE CONSECUTIVE
MORNING, WITH DENSE FOG NOT EXPECTED.
AVIATION
(18Z TAFS)
ISSUED AT 1223 PM CDT SUN APR 12 2026
GUSTY WINDS ACROSS THE REGION TODAY AS A COLD FRONT STALLS TO THE
NORTHWEST OF THE AREA. A COMPLEX OF THUNDERSTORMS WILL MAKE A RUN
TOWARDS THE AREA LATE THIS AFTERNOON AND OVERNIGHT, BUT AT THIS
TIME CONFIDENCE IS TOO LOW TO INCLUDE IN THE FORECAST OF IF THIS
WILL ACTUALLY MAKE IT ANY OF THE TERMINALS.
MARINE
ISSUED AT 1241 AM CDT SUN APR 12 2026
HIGH PRESSURE OVER THE SOUTHEASTERN U.S. WILL MAINTAIN EAST TO
SOUTHEAST WINDS ACROSS THE NORTHERN GULF FOR THE NEXT SEVERAL DAYS
WITH SEAS REMAINING CONSISTENTLY BETWEEN 2-3 FEET OVER THE NEARSHORE
COASTAL WATERS AND 3-5 FEET OVER THE OUTER COASTAL WATERS. A FEW
SMALL SHOWERS WILL BE POSSIBLE ACROSS THE COASTAL WATERS OF
SOUTHEAST TEXAS TODAY AND SUNDAY, BUT NO PRECIPITATION IS EXPECTED
MONDAY THROUGH FRIDAY.
FIRE WEATHER
ISSUED AT 1241 AM CDT SUN APR 12 2026
WHILE WINDS WILL CONTINUE TO BE BREEZY AT TIMES RELATIVE HUMIDITY
VALUES WILL INCREASE AS MOISTURE CONTINUES TO BE TRANSPORTED IN FROM
THE GULF. A FRONTAL BOUNDARY WILL STALL NORTHWEST OF THE AREA, BUT
COULD PROVIDE A FEW SPOTTY SHOWERS ACROSS SOUTHEAST TEXAS.
