KEY MESSAGES
UPDATED AT 639 PM CDT WED JUL 8 2026
- SUMMER HEAT AND HUMIDITY TO CONTINUE THROUGHOUT THE WEEK AND
WEEKEND. HEAT INDICES NEAR 100 DEGREES ARE POSSIBLE THROUGH THE
END OF THE WEEK, MAINLY WEST OF THE PLATEAU.
- DAYTIME SHOWERS AND STORMS ARE EXPECTED FOR THE NEXT SEVERAL
DAYS. AT THIS TIME, THE RISK OF SEVERE STORMS REMAINS VERY LOW,
BUT HEAVY RAINFALL AND LOCALIZED FLOODING CAN BE EXPECTED WITH
STRONGER, SLOWER-MOVING STORMS.
SHORT TERM
(REST OF TODAY THROUGH THURSDAY)
ISSUED AT 1143 AM CDT WED JUL 8 2026
AS A LOW PRESSURE SYSTEM SWIRLS NEAR THE BOOTHEEL OF MO ON
SATELLITE, SHOWERS AND THUNDERSTORMS ARE BEGINNING TO KICK OFF IN
MIDDLE TENNESSEE. WE'RE EXPECTING COVERAGE TO INCREASE AS THE LOW
PUSHES EAST THIS AFTERNOON AND EVENING. WHILE SOME OF THESE
THUNDERSTORMS WILL BE LOUD, PRODUCE HEAVY DOWNPOURS, AND MAYBE
INCLUDE SOME GUSTY WINDS, WE'RE NOT EXPECTING ANY SEVERE STORMS
TODAY. SHEAR IS EXTREMELY LOW, MEANING THE STORMS WON'T BE ABLE TO
REALLY SUSTAIN THEMSELVES LONG ENOUGH TO BECOME SEVERE DESPITE A
FAIR AMOUNT OF INSTABILITY. HIGHS WILL GET INTO THE MID TO UPPER
80S, WITH HEAT INDICES IN THE 90S THIS AFTERNOON.
THURSDAY WILL BE SIMILAR FOR THE AREA, WITH WARMER HIGHS IN THE MID
80S TO LOW 90S. WAA WILL CONTINUE FOR THE AREA THROUGH SATURDAY
ALOFT, BUT THE TEMPERATURES WILL HAVE TO CONTEND WITH THE
PRECIPITATION. DESPITE THIS, WE WILL STILL HAVE HEAT INDICES IN THE
UPPER 90S TO LOW 100S BOTH THURSDAY AND FRIDAY. WHILE THE OUTLOOKED
AREA REMAINS NORTH OF THE KY/TN STATE LINE, WE'RE STILL LOOKING AT
SCATTERED SHOWERS AND THUNDERSTORMS BEGINNING AS EARLY AS THE
MORNING HOURS ON THURSDAY. GREATEST CHANCES FOR THUNDERSTORMS SEEMS
TO BE EAST OF I-65 CURRENTLY, BUT OTHER LOCATIONS COULD SEE THEM AS
WELL. AGAIN, WE ARE NOT EXPECTING SEVERE STORMS AT THIS TIME.
LONG TERM
(THURSDAY NIGHT THROUGH NEXT WEDNESDAY)
ISSUED AT 1143 AM CDT WED JUL 8 2026
INTO THE WEEKEND, AS VARIOUS RAIN CHANCES CAREEN THROUGH MIDDLE
TENNESSEE, OUR CHANCES FOR FLOODING WILL ALSO INCREASE AS HIGH PWATS
CONTINUE TO BE A THREAT. GIVEN THE ALREADY SATURATED SOILS, AND THE
RISK FOR ANOTHER 3 TO 4 INCHES THROUGH SUNDAY, A FLOOD WATCH HAS
BEEN ISSUED FOR THURSDAY THROUGH SUNDAY. WE COULD ALSO SEE SOME
ISOLATED SEVERE STORMS FRIDAY INTO SATURDAY, AS WE ARE IN A MARGINAL
(LEVEL 1 OUT OF 5) OUTLOOK FOR SEVERE WEATHER FROM SPC. MARGINAL IS
THE BEST WORD TO DESCRIBE OUR RISK, AS SHEAR REMAINS IN THE BARELY
DOUBLE DIGITS WHICH IS FAR BELOW WHAT IS NECESSARY FOR SUSTAINED
STORMS BUT CAPE IS HIGH ACROSS THE REGION. SIMILAR SETUPS TO WHAT'S
GOING ON IN THE SHORT TERM, WITH THE ADDITION OF SOME REMNANT
OUTFLOW BOUNDARIES FROM PREVIOUS STORMS. HAZARDS RIGHT NOW LOOK TO
BE MAINLY GUSTY WINDS AND HEAVY RAIN, WITH NO TORNADO RISK EXPECTED
AT THIS TIME.
INTO NEXT WEEK, THINGS LOOK WARMER, YET DRIER. I DON'T MEAN FEWER
RAIN CHANCES, I MEAN LESS HUMIDITY. WALKING OUTDOORS WILL NO LONGER
FEEL LIKE WALKING THROUGH A SWIMMING POOL, WITH HEAT INDICES
FORECASTED TO BE CLOSE TO AIR TEMPERATURE THROUGH MID-WEEK NEXT
WEEK. UNFORTUNATELY, IT DOES APPEAR AS RAIN CHANCES WILL CONTINUE AS
NW FLOW WILL SET UP OVER MIDDLE TENNESSEE AS WE FIND OURSELVES EAST
OF A STRENGTHENING RIDGE FOR THE BEGINNING OF THE WORK WEEK.
AVIATION
(00Z TAFS)
ISSUED AT 639 PM CDT WED JUL 8 2026
TO THE SURPRISE OF ABSOLUTELY NO ONE, MORE STORMS HAVE DEVELOPED
IN THE WARM, UNSTABLE AND VERY HUMID MIDDLE TENNESSEE AIR MASS AS
WE HEAD INTO THE EVENING. THE TERMINALS COULD BE IMPACTED TO
VARIOUS DEGREES DURING THE NEXT 1 TO 2 HOURS, BUT WE EXPECT THE
ACTIVITY TO REALLY NOSEDIVE AFTER SUNSET. WE'VE INCLUDED SOME
LIGHT RADIATION FOG AT A FEW OF THE TERMINALS FOR THE OVERNIGHT
AND EARLY MORNING PERIOD, BUT WINDS MAY STAY UP JUST ENOUGH TO
KEEP IT FROM GETTING TOO DENSE. OF COURSE, WE'VE MADE MENTION OF
MORE AFTERNOON CONVECTIVE POSSIBILITIES FOR THURSDAY.
