SHORT TERM
(TODAY THROUGH MONDAY NIGHT)
ISSUED AT 252 AM CDT SAT MAY 24 2025
CALM CURRENT CONDITIONS WITH TEMPS IN THE 70S AND AREAS OF FOG.
WINDS ARE HELPING TO PREVENT WIDESPREAD DENSE FOG. HOWEVER THERE
COULD BE AREAS OF PATCHY TO DENSE FOG OVER THE NEXT FEW HOURS.
ISOLATED TO SCATTERED SHOWERS AND STORMS WILL BE POSSIBLE, MAINLY
OVER THE AFTERNOON TO EVENING HOURS TODAY AND TOMORROW. BY MONDAY,
HEAVIER SHOWERS AND STORMS POSSIBLE. A MARGINAL RISK ERO COVERS

LONG TERM
(TUESDAY THROUGH SATURDAY)
ISSUED AT 252 AM CDT SAT MAY 24 2025
THE EXTENDED PERIOD WILL FEATURE A CONTINUATION OF THE UNSETTLED
WEATHER PATTERN ESTABLISHED DURING THE SHORT TERM. A PERSISTENT
SOUTHERLY FLOW, COMBINED WITH AMPLE DEEP LAYER MOISTURE, WILL
INTERACT WITH A SERIES OF EMBEDDED SHORTWAVE DISTURBANCES,
SUPPORTING SUSTAINED CONVECTIVE ACTIVITY THROUGHOUT THE PERIOD. AT
THE BEGINNING OF THE LONG TERM , WIDESPREAD SHOWERS AND
THUNDERSTORMS ARE EXPECTED AS A FRONTAL BOUNDARY CONTINUES TO
PROGRESS SOUTHWARD INTO THE SOUTHERN PLAINS. WHILE PRECIPITATION
WILL BE WIDESPREAD ACROSS THE FORECAST AREA, HEAVIER RAINFALL
RATES ARE ANTICIPATED FARTHER INLAND, PARTICULARLY ACROSS CENLA
AND AREAS NORTH OF THE FA. TUESDAY, THE NORTHERN HALF OF THE
CWA WILL HAVE A MARGINAL RISK OF FLASH FLOODING, WITH EVEN
GREATER POTENTIAL JUST NORTH OF THE CWA AND INTO PARTS OF CENLA.
THE AFOREMENTIONED FRONT IS EXPECTED TO GRADUALLY LOSE MOMENTUM
AND BECOME QUASISTATIONARY AS IT TEMPORARILY SETTLES ACROSS THE
GULF COAST. BY WEDNESDAY, THE THREAT FOR EXCESSIVE RAINFALL AND
ASSOCIATED FLASH FLOODING WILL EXPAND TO ENCOMPASS NEARLY THE
ENTIRE CWA. GIVEN THE ANTICIPATED SLOW MOVEMENT AND PERSISTENCE OF
THE BOUNDARY, CONTINUED ROUNDS OF CONVECTION ARE LIKELY, AND
ADDITIONAL DAYS WITH HIGHLIGHTED EXCESSIVE RAINFALL RISK CANNOT BE
RULED OUT. ALTHOUGH WIDESPREAD SEVERE WEATHER IS NOT CURRENTLY
FORECAST, ISOLATED STRONG TO MARGINALLY SEVERE STORMS REMAIN
POSSIBLE AND WILL REQUIRE CLOSE MONITORING IN THE COMING DAYS.
CLOUD COVER AND PRECIPITATION WILL HELP TO MODERATE DAYTIME
TEMPERATURES, GENERALLY KEEPING THEM NEAR CLIMATOLOGICAL NORMS FOR
THIS TIME OF YEAR.
