NATIONAL WEATHER SERVICE NASHVILLE TN
1028 PM CDT SAT SEP 5 2026
..NEW SHORT TERM, LONG TERM
KEY MESSAGES
UPDATED AT 1021 PM CDT SAT SEP 5 2026
- MAJOR HEAT RISK AND TRIPLE DIGIT HEAT INDICES CONTINUE ACROSS
SOUTHWEST MIDDLE TN WITH A HEAT ADVISORY REMAINING IN EFFECT
UNTIL 8 PM SUNDAY.
- HEAT RISK LESSENS EARLY NEXT WEEK, BUT TEMPERATURES REMAIN
ABOVE-NORMAL THROUGH THE FORECAST PERIOD.
- RAIN CHANCES ARE LOW THROUGH THIS WEEK.
SHORT TERM
(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 1021 PM CDT SAT SEP 5 2026
A WEAK DISTURBANCE IS PASSING THROUGH THE AREA THIS EVENING, AND AN
UNSTABLE ENVIRONMENT WILL CONTINUE TO SUPPORT A LOW CHANCE FOR
THUNDERSTORMS THROUGH ABOUT MIDNIGHT. MAIN CONCERN WILL CONTINUE TO
BE STRONG WINDS DUE TO INVERTED-V SOUNDINGS AND PLENTY OF DCAPE.
ONCE THUNDERSTORMS DIMINISH, A CALM NIGHT IS THEN IN STORE WITH
JUST THE DEVELOPMENT OF PATCHY FOG, PARTICULARLY ACROSS THE
PLATEAU, TO WATCH. DRY CONDITIONS EXPECTED ON SUNDAY WITH A LITTLE
BIT OF A DIP IN THE TEMPERATURES. LOOK FOR HIGHS IN THE UPPER-80S
FOR THE PLATEAU AND INTO THE MID-90S ELSEWHERE. STILL ABOVE
NORMAL, BUT CERTAINLY BETTER THAN THE THREE CONSECUTIVE DAYS OF
TRIPLE DIGITS THAT BNA HAS RECORDED. THANKS TO THE DRIER AIR, HEAT
INDICES WILL ALSO STAY BELOW 100 WITH THE EXCEPTION BEING ACROSS
THE SOUTHWEST WHERE A HEAT ADVISORY REMAINS IN EFFECT THROUGH
SUNDAY FOR THOSE COUNTIES.
TEMPERATURES COOL A LITTLE BIT MORE ON MONDAY WITH HIGHS IN THE MID-
80S FOR THE PLATEAU AND INTO THE LOW-90S WEST OF IT. MOST OF THE
AREA REMAINS DRY, BUT ANOTHER WEAK DISTURBANCE ALLOWS FOR LOW TO
MEDIUM STORM CHANCES ACROSS THE PLATEAU.
LONG TERM
(TUESDAY THROUGH NEXT SUNDAY)
ISSUED AT 1021 PM CDT SAT SEP 5 2026
UNFORTUNATELY, THE MAIN STORY CONTINUES TO BE THE HEAT. BY TUESDAY,
THE HIGH PRESSURE SHIFTS BACK OVER THE SOUTHEASTERN US, AND
TEMPERATURES WILL WARM IN RESPONSE. HIGHS WILL BE BACK IN THE MID-
90S WEDNESDAY. IT WON'T BE QUITE AS HOT AND HUMID AS WHAT WE'VE
BEEN EXPERIENCING LATELY, BUT IT'LL STILL BE UNCOMFORTABLE WITH
TEMPERATURES THAT ARE WELL ABOVE NORMAL FOR SEPTEMBER. A PATTERN
CHANGE ON THURSDAY BRINGS A FRONT INTO THE AREA WHICH INCREASES
RAIN CHANCES INTO THE WEEKEND. WHILE THIS FRONT DROPS TEMPERATURES
SOME, IT WON'T BE AS STRONG AS YOU MAY HOPE FOR AS ABOVE NORMAL
TEMPERATURES CONTINUE TO BE FAVORED.
