SHORT TERM
(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 1209 PM CDT SAT AUG 23 2025
A STATIONARY FRONT IS LOCATED ALONG THE COAST WITH EXTENSIVE
SHOWERS AND THUNDERSTORMS FORMING ALONG THE BOUNDARY. SATELLITE-
DERIVED PWAT SHOWS THE LINE OF DRY AIR HAS REACHED CENTRAL
LOUISIANA, WITH GROUND OBSERVATIONS ALSO SHOWING A SLIGHT DROP IN
DEW POINTS AT THE SURFACE. THIS TREND WILL THANKFULLY CONTINUE AS
AN UPPER-LEVEL RIDGE IN THE DESERT SOUTHWEST WILL CREATE A
NORTHERLY FLOW, PUSHING THE DRY CONTINENTAL AIRMASS TO THE GULF
COAST. THIS DRY AIR INTRUSION WILL BE STRONG, WITH PWATS EXPECTED
TO BE NEAR OR BELOW THE 10TH PERCENTILE THROUGH THE MIDDLE OF THE
WEEK.
WEATHER-WISE, WE ARE LOOKING AT SOME WONDERFUL WEATHER, ESPECIALLY
FOR LATE AUGUST, WITH MOSTLY CLEAR SKIES, TEMPERATURES IN THE LOW
90S, AND DEW POINTS IN THE LOW 70S.
LONG TERM
(TUESDAY THROUGH NEXT FRIDAY)
ISSUED AT 1209 PM CDT SAT AUG 23 2025
A SECOND COLD FRONT WILL MOVE ACROSS THE CWA ON MONDAY AND
TUESDAY, BRINGING ANOTHER SHOT OF COOLER AND DRY AIR. WITH THIS
FRONT, RAIN CHANCES WILL BE ON THE LOWER SIDE, AROUND 30%. RAIN
CHANCES BEHIND THE FRONT WILL DROP AS THE DRY AIR SETTLES IN
PLACE. SOUTHERN FLOW WILL START TO PICK UP LATE IN THE WEEK AS
HIGH PRESSURE STARTS TO BUILD ALONG THE EASTERN SEABOARDS.
THE PLEASANT WEATHER WILL CONTINUE NEXT WEEK, WITH HIGHS STAYING
IN THE LOW 90S ALL WEEK. INLAND AREAS COULD EVEN SEE LOWS IN THE
MID-60S LATER IN THE WEEK.
