DISCUSSION
ISSUED AT 137 PM EDT THU SEP 24 2026
CURRENTLY A FEW LINGERING SHOWERS ACROSS PARTS OF THE PLATEAU AND
THE SOUTHERN APPALACHIAN MOUNTAINS EARLY THIS AFTERNOON. WE SHOULD
CONTINUE TO SEE THESE SLOWLY WORK THEIR WAY THROUGH THE REGION AS
THE TROUGH ALSO SWINGS THROUGH OVERHEAD... NO MAJOR IMPACTS ARE
EXPECTED FROM THESE SHOWERS AND FEW THUNDERSTORMS.
MORE NOTABLE IS THAT IT'S TURNED MUCH COOLER TODAY AND EVEN WITH THE
SUN TRYING TO COME OUT IT'S GOING TO FEEL LIKE FALL WITH
TEMPERATURES MUCH LOWER THAN THE PREVIOUS WEEKS. THIS FALL LIKE
WEATHER WILL CONTINUE THROUGH THE WEEKEND WITH MOSTLY CLEAR SKIES
AND LOWER DEW POINTS. RAIN CHANCES DON'T LOOK TO RETURN UNTIL AT
LEAST THE MIDDLE OF THE WEEK NEXT WEEK. A LOW AND FRONT LOOK TO TRY
AND MOVE THROUGH THE US, BUT MODELS DISAGREE WITH THE TIMING AND THE
STRENGTH. BUT THAT'S A PROBLEM FOR NEXT WEEK, IN THE MEANTIME ENJOY
THE WEATHER FOR THE NEXT SEVERAL DAYS.

A COOLING AIR MASS AND MOIST GROUND FROM EARLIER RAINFALL SUGGEST
A SETUP FOR FOG AND/OR LOW CIGS TONIGHT. THE CAVEAT IS THAT LOWER
DEWPOINTS WILL BE LEAKING INTO THE AREA FROM THE NORTH, AND IF
THEY LOWER ENOUGH, FOG WON'T HAPPEN. CHA APPEARS LIKELY TO HAVE
MVFR CIGS OVERNIGHT, WITH TYS POTENTIALLY THE SAME BUT WITH LOWER
CONFIDENCE. TRI FAVORS FOG WITH CLEARING SKIES AND CALM WINDS, BUT
AGAIN, HOW LOW DEWPOINTS FALL IS UNCERTAIN.
