DISCUSSION
(TODAY THROUGH WEDNESDAY)
ISSUED AT 1200 AM CDT THU APR 30 2026
A FRONT HAS MOVED ACROSS THE REGION AND IS NOW NEAR THE COASTLINE
WHERE IT WILL STALL OUT. THE MAIN IMPACT FROM THIS FRONT WILL BE
WIDESPREAD RAIN AND THE POSSIBILITY OF FLASH FLOODING. WITH THE
FRONT STALLED ALONG THE COAST, WE WILL HAVE HIGH RAIN CHANCES
THROUGH THE END OF THE WEEK. ON FRIDAY, WE HAVE A SLIGHT RISK
(LEVEL 2 OF 4) FOR FLASH FLOODING, AS PWAT VALUES WILL BE WELL
ABOVE THE 90TH PERCENTILE, WITH VALUES AROUND 1.7 INCHES. IN
ADDITION, FORECAST SOUNDINGS SHOW AN ATMOSPHERE THAT IS SATURATED
WITH LONG SKINNY CAPE. THE RAINFALL IS A WELCOME DEVELOPMENT AS AN
ONGOING SEVERE DROUGHT CONTINUES TO IMPACT THE REGION. RAINFALL
TOTALS THROUGH FRIDAY WILL BE BETWEEN 1 TO 4 INCHES, WITH HEAVIER
RAINFALL EXPECTED ABOVE I-10.
AS WE HEAD INTO THE WEEKEND, THE FRONT WILL WASH AWAY, WITH
COOLER TEMPERATURES AND DRY AIR FOLLOWING BEHIND IT. THIS WEEKEND
WILL HAVE SPECTACULAR WEATHER, AND THERE ARE LOW-END CHANCES,
AROUND 10%, THAT PARTS OF CENTRAL LOUISIANA COULD SEE RECORD LOW
AFTERNOON HIGH TEMPERATURES ON SATURDAY, WITH FORECASTED HIGHS IN
THE LOW 70S ALONG THE COAST AND THE MID-60S FARTHER NORTH.
FOR THE REST OF THE FORECAST, WE ARE LOOKING AT DRY WEATHER AND A
SLOW WARM-UP TO MORE SEASONABLE TEMPERATURES, WITH HIGHS BACK IN
THE 80S BY THE MIDDLE OF THE WEEK.

SHOWERS AND STORMS HAVE CONTINUED THROUGH THE NIGHT ACROSS PARTS
OF CENLA. WHILE THIS IS EXPECTED TO TAPER OUT, IT WILL BE FOLLOWED
BY YET ANOTHER ROUND OF CONVECTION LATER THIS MORNING OR THIS
AFTERNOON AT THE LATEST, THEN CONTINUING THROUGH THE EVENING.
MARINE
ISSUED AT 1200 AM CDT THU APR 30 2026
A FRONT WILL STALL ALONG THE COAST TONIGHT AND ON THURSDAY,
CREATING CLOUDY AND AT TIMES STORMY CONDITIONS. A SMALL CRAFT
ADVISORY MAY BE NEEDED ON FRIDAY AS WINDS INCREASE, BUT OVERALL,
CONDITIONS ARE EXPECTED TO REMAIN BENIGN.
FIRE WEATHER
ISSUED AT 1200 AM CDT THU APR 30 2026
A SERIES OF WETTING RAINS WILL BRING BETWEEN 1 TO 4 INCHES OF RAIN
ACROSS THE REGION THROUGH FRIDAY, WITH MOST AREAS GETTING AT LEAST
0.25 INCHES. WITH THE ONGOING DROUGHT, THIS RAINFALL WILL HELP
DROP OUR KBDI. BEHIND THE DISTURBANCES, DRY AND COOL AIR WILL FLOW
IN, WITH MINIMUM RH VALUES DOWN INTO THE 30S OVER THE WEEKEND AND
INTO NEXT WEEK. THANKFULLY, WINDS WILL BE CALM THROUGH THE
WEEKEND, AND NO ENHANCED FIRE DANGER IS EXPECTED. NEXT WORK WEEK
WILL BE DRY, WITH CONDITIONS SLOWLY BECOMING MORE HUMID.
