DISCUSSION
ISSUED AT 331 PM CDT TUE MAR 24 2026
UNSEASONABLY WARM CONDITIONS ARE ONGOING TODAY, WITH TEMPERATURES
RISING INTO THE UPPER 70S TO LOWER 80S. THE WEAK FRONTAL BOUNDARY
THAT MOVED THROUGH EARLIER HAS STALLED JUST OFFSHORE OVER THE
COASTAL WATERS. THIS BOUNDARY IS EXPECTED TO GRADUALLY WEAKEN AND
DISSIPATE AS IT ATTEMPTS TO RETROGRADE INLAND ACROSS PORTIONS OF
THE CWA. IN ITS WAKE, SOUTHERLY FLOW HAS REESTABLISHED ACROSS THE
REGION IN RESPONSE TO SURFACE HIGH PRESSURE CENTERED OVER THE
CENTRAL TO EASTERN GULF.
LOW LEVEL MOISTURE ADVECTION WILL INCREASE THROUGH TONIGHT,
RESULTING IN A CORRESPONDING INCREASE IN CLOUD COVER AND THE
POTENTIAL FOR ANOTHER ROUND OF PATCHY TO LOCALLY DENSE FOG. WHILE
A DENSE FOG ADVISORY HAS NOT BEEN ISSUED AT THIS TIME, (GIVEN THAT
CURRENT MODEL GUIDANCE DOES NOT CONSISTENTLY INDICATE VISIBILITIES
FALLING BELOW A QUARTER MILE) CONDITIONS WILL CONTINUE TO BE
MONITORED CLOSELY. REGARDLESS, REDUCED VISIBILITIES ARE POSSIBLE,
AND HAZARDOUS TRAVEL CONDITIONS MAY DEVELOP DURING THE EARLY
MORNING HOURS.
LITTLE CHANGE IN THE OVERALL SYNOPTIC PATTERN IS EXPECTED THROUGH
THE REMAINDER OF THE WORK WEEK. AT THE SURFACE, PERSISTENT
SOUTHERLY FLOW WILL CONTINUE AS THE AFOREMENTIONED HIGH GRADUALLY
SHIFTS EASTWARD ACROSS THE GULF. ALOFT, RIDGING CURRENTLY
POSITIONED OVER THE DESERT SOUTHWEST WILL MIGRATE EASTWARD INTO
TEXAS, MAINTAINING ABOVE NORMAL TEMPERATURES. THIS PATTERN WILL
SUPPORT A CONTINUED “EARLY SUMMERISH” REGIME, INCLUDING MULTIPLE
OPPORTUNITIES FOR NOCTURNAL FOG DEVELOPMENT.
BY LATE WEEK INTO THE WEEKEND (FRIDAY INTO SATURDAY), A MORE
“ROBUST” COLD FRONT IS EXPECTED TO PROGRESS THROUGH THE REGION AS
THE UPPER RIDGE BECOMES SUPPRESSED AND FLATTENS. THIS FRONTAL
PASSAGE IS ANTICIPATED TO REMAIN LARGELY DRY; HOWEVER, IT WILL
USHER IN A COOLER AND DRIER AIRMASS, WITH TEMPERATURES RETURNING
CLOSER TO CLIMO NORMALS ON SATURDAY. NORTHERLY FLOW IN THE WAKE
OF THE FRONT WILL BE SHORT LIVED, AS SURFACE HIGH PRESSURE QUICKLY
SHIFTS EASTWARD TOWARD THE ATLANTIC SEABOARD. RETURN FLOW IS
EXPECTED TO BECOME REESTABLISH BY SUNDAY, ALLOWING TEMPERATURES
AND MOISTURE TO REBOUND HEADING INTO THE EARLY PART OF THE
FOLLOWING WORK WEEK.
