UPDATE
ISSUED AT 613 PM CDT THU SEP 24 2026
TODAY IS GOING TO END UP THE 29TH STRAIGHT DAY WITHOUT MEASURABLE
RAINFALL AT BNA; THE ALL-TIME RECORD IS 36. NEEDLESS TO SAY, DROUGHT
CONDITIONS HAVE QUICKLY SPREAD ACROSS THE MAJORITY OF MIDDLE
TENNESSEE, AND WE ARE STILL SEVERAL DAYS AWAY FROM OUR NEXT
APPRECIABLE RAIN CHANCES. IN THE NEAR TERM, THERE ARE A FEW SPOTTY
SHOWERS SHOWING UP ALONG THE CUMBERLAND PLATEAU, BUT THATS ALL WE
ARE GETTING TODAY. AT THE SURFACE, A PESKY TROUGH OF LOW PRESSURE
REMAINS SITUATED ALONG THE APPALACHIANS, WHILE MIDDLE TENNESSEE
FINDS ITSELF BETWEEN A DEEP UPPER LOW OVER THE CAROLINAS AND AN
UPPER RIDGE ALIGNED WEST OF THE MISSISSIPPI VALLEY. SO THE
ENVIRONMENT ACROSS THE LOCAL AREA REMAINS QUITE DRY AND STABLE, WITH
A NORTHERLY FLOW MORE OR LESS THROUGH THE ENTIRE COLUMN. OVERNIGHT,
WE DO EXPECT PATCHY FOG TO DEVELOP, MAINLY IN AREAS SOUTH OF I-40.
OTHERWISE, LOOK FOR AUTUMN-LIKE CONDITIONS TO LAST AT LEAST THROUGH
THE WEEKEND.
SHORT TERM
(REST OF TODAY THROUGH FRIDAY)
ISSUED AT 1110 AM CDT THU SEP 24 2026
IT'S BEEN ANOTHER LOW OVERCAST MORNING SO FAR ACROSS MOST OF THE
AREA. VISIBLE SATELLITE IS SHOWING SOME BREAKS DEVELOPING IN THE
STRATUS DECK AND THAT TREND WILL CONTINUE THROUGH THE AFTERNOON
ALLOWING FOR SOME SUN TO RETURN. THIS WILL HELP TEMPERATURES WARM A
LITTLE MORE THAN YESTERDAY, BUT HIGHS WERE STILL KNOCKED DOWN A
COUPLE OF DEGREES FROM NBM GUIDANCE. WE'VE SEEN SOME SHOWERS ON THE
PLATEAU THIS MORNING AND THOSE LOW TO MEDIUM CHANCES WILL CONTINUE
THROUGH THE AFTERNOON.
THE LARGE UPPER TROUGH WILL CONTINUE TO SIT OVER THE EASTERN
FOURTH OF THE CONUS ON FRIDAY WITH A REINFORCING SHOT OF COOL AIR
FILTERING IN FRIDAY NIGHT. THIS MEANS TEMPERATURES WILL BE IN THE
50S ACROSS THE AREA FOR SUNRISE ON SATURDAY. A FEW SPOTS ALONG
THE PLATEAU MAY EVEN DIP INTO THE UPPER 40S.
LONG TERM
(FRIDAY NIGHT THROUGH NEXT THURSDAY)
ISSUED AT 1110 AM CDT THU SEP 24 2026
THE WEEKEND IS LOOKING SPLENDID WITH HIGHS IN THE MID 70S TO LOW
80S. FORTUNATELY AND UNFORTUNATELY, THE WEEKEND WILL BE DRY AND THAT
WILL CONTINUE INTO EARLY NEXT WEEK. A LARGE TROUGH WILL TRY TO
PROGRESS ACROSS THE MOUNTAIN WEST AND PLAINS DURING THE MID WEEK
PERIOD BUT THERE ARE SOME DISCREPANCIES ON HOW PROGRESSIVE THIS
TROUGH WILL BE. THIS WILL AFFECT OUR RAIN CHANCES FROM WEDNESDAY
AND ONWARD. WE CERTAINLY NEED THE RAIN WITH THE NEW DROUGHT
STATEMENT SHOWING ABNORMALLY DRY TO MODERATE DROUGHT CONDITIONS
ACROSS THE MAJORITY OF THE AREA.
AVIATION
(00Z TAFS)
ISSUED AT 620 PM CDT THU SEP 24 2026
SURFACE WINDS REMAIN NORTHERLY ACROSS MIDDLE TENNESSEE AS A SURFACE TROUGH
TO OUR EAST REFUSES TO BUDGE. WE DO EXPECT A BROAD AREA OF RADIATION FOG TO
DEVELOP DURING THE OVERNIGHT AND EARLY MORNING PERIOD, WHICH WILL IMPACT THE
CUMBERLAND PLATEAU THE GREATEST. EXPECT VFR WX TOMORROW ONCE THE FOG AND LOW
STRATUS DISSIPATE.
