ISSUED AT 1144 PM CDT THU SEP 24 2026
CLOUDS LINGER ACROSS THE SOUTHEAST THIS EVENING BUT SHOULD
GRADUALLY CLEAR, THOUGH STUBBORN CLOUD COVER MAY PERSIST SOUTH OF
I-85 THROUGH FRIDAY MORNING. WITH CLEARING SKIES AND COOLER
TEMPERATURES, PATCHY FOG WILL BE POSSIBLE, ESPECIALLY NEAR
WATERWAYS, POTENTIALLY IMPACTING THE MORNING COMMUTE. MORNING
TEMPERATURES ARE EXPECTED TO BE 5 TO 10 DEGREES COOLER THAN
24 HOURS AGO. PERSISTENT NORTHERLY FLOW WILL CONTINUE ADVECTING
COOL, DRY AIR THROUGH THE WEEKEND, PUSHING LOW TEMPERATURES TO
THEIR LOWEST POINT SATURDAY MORNING, WITH MID 50S NORTHEAST TO
LOWER 60S SOUTHWEST.
THE FORECAST REMAINS DRY AND COOL THROUGH SUNDAY, WITH HEAT
INDICES CLOSE TO THE ACTUAL TEMPERATURES. MODEL GUIDANCE BEGINS
TO DIVERGE BY MONDAY, EXHIBITING A SLOWER TREND WITH THE NEXT
FRONTAL BOUNDARY. A WEAK TROUGH AND SURFACE LOW PRESSURE SYSTEM
WILL TRACK EASTWARD NEXT WEEK, BRINGING THE NEXT PRECIPITATION
CHANCES. GIVEN THE SLOWER MOVEMENT, RAIN IS EXPECTED TO ENTER THE
STATE AROUND MID- WEEK OR SLIGHTLY LATER.
SOUTHERLY BEGINS TO INCREASE SLOWLY BY TUESDAY AND WEDNESDAY.
THIS RETURN FLOW WILL DRIVE A GRADUAL WARMING TREND AND SLOW
MOISTURE RECOVERY, ALTHOUGH WE MAY REMAIN DRY AT LEAST THROUGH
THURSDAY MORNING. UNFORTUNATELY IT DOES NOT LOOK LIKE WE HAVE SEE
THE END OF THE UPPER 80S TO LOW 90S AS MODELS ARE HINTING AT
ANOTHER ROUND OF WARM TEMPERATURES TO USHER IN OCTOBER.
