SHORT TERM
(TODAY THROUGH FRIDAY NIGHT)
ISSUED AT 1200 AM CST WED MAR 4 2026
QUIET BUT HUMID CONDITIONS PERSIST EARLY THIS MORNING WITH
SLIGHTLY ELEVATED SOUTHERLY TO SOUTHEASTERLY FLOW. TEMPERATURES
ARE A TOUCH WARMER TONIGHT GENERALLY IN THE 60S WITH DEWPOINTS
NEARLY MATCHING AMBIENT TEMPERATURES. PATCHY TO DENSE MARINE FOG
CONTINUES TO ADVECT INTO THE AREA, PARTICULARLY INTO AREAS SOUTH
OF THE I-10 CORRIDOR. WHILE AN INLAND DENSE FOG ADVISORY HAS NOT
BEEN ISSUED AT THIS MOMENT, IT IS ADVISED TO TRAVEL WITH CAUTION.
ALOFT, AN UPPER LEVEL RIDGE IS CENTERED OVER THE CENTRAL TO
EASTERN GULF. THE UPPER RIDGE WILL CONTINUE TO WEAKEN AND SHIFT
EASTWARD ACROSS FL AND INTO THE ATLANTIC AS A DISTURBANCE ADVANCES
INTO THE CENTRAL CONUS. AN ASSOCIATED FRONTAL BOUNDARY WILL MOVE
SOUTHWARD INTO THE SOUTHERN PLAINS BUT IS EXPECTED TO WEAKEN AND
STALL NORTH OF THE AREA. DESPITE THE WEAKENING FRONT, SUFFICIENT
MOISTURE MAY SUPPORT WIDELY ISOLATED SHOWERS THROUGH THE END OF
THE WORK WEEK.
ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH THE REMAINDER OF
THE SHORT TERM, WITH BOTH DAYTIME HIGHS AND OVERNIGHT LOWS RUNNING
APPROXIMATELY 10 TO 15 DEGREES ABOVE CLIMATOLOGICAL NORMALS. DAILY
TEMPERATURE RECORDS MAY BE TIED OR BROKEN AT SELECT LOCATIONS.
LONG TERM
(SATURDAY THROUGH NEXT TUESDAY)
ISSUED AT 1200 AM CST WED MAR 4 2026
ANOTHER FRONTAL BOUNDARY IS FORECAST TO APPROACH THE REGION THIS
WEEKEND BUT IS AGAIN EXPECTED TO STALL AND EVENTUALLY
RETREAT/BREAKDOWN. REGARDLESS, THE BOUNDARY AND DAYTIME HEATING
WILL PROVIDE A FOCUS FOR SHOWER AND THUNDERSTORM DEVELOPMENT,
PARTICULARLY ACROSS THE NORTHERN PORTIONS OF THE CWA.
ALOFT, AN UPPER TROUGH WILL PROGRESS FROM THE PACNW INTO THE
WESTERN ROCKIES WHILE A CUTOFF LOW DEVELOPS OFF THE BAJA
CALIFORNIA COAST. MOISTURE WILL REMAIN ABUNDANT ACROSS THE REGION,
AND GUIDANCE SUGGESTS THE CUTOFF LOW SHALL SLOWLY TRACK EASTWARD
INTO THE SOUTHERN PLAINS. THIS EVOLUTION WILL LIKELY SUPPORT
ANOTHER ROUND OF SHOWERS AND STORMS EARLY TO MID NEXT WEEK.
