..NEW UPDATE, AVIATION
KEY MESSAGES
UPDATED AT 623 PM CDT THU SEP 10 2026
- ABOVE-NORMAL TEMPERATURES WILL CONTINUE WITH HIGHS IN THE LOW
90S FOR MOST AREAS THROUGH THE NEXT SEVEN DAYS.
- CHANCES FOR SCATTERED SHOWERS AND STORMS WILL INCREASE THROUGH
THE NEXT COUPLE OF DAYS WITH HIGH RAIN CHANCES ACROSS THE AREA
SATURDAY.
- LOW CHANCE FOR A FEW STORMS WITH STRONG GUSTY WINDS AND BRIEF
FLASH FLOODING THROUGH SATURDAY.
UPDATE
ISSUED AT 623 PM CDT THU SEP 10 2026
THUNDERSTORMS ARE DEVELOPING THIS EVENING MAINLY ACROSS AREAS
NORTH OF I-40, ESPECIALLY DUE TO THE INFLUENCE OF OUTFLOW
BOUNDARIES. THESE STORMS SO FAR HAVE A HISTORY OF PRODUCING GUSTY
WINDS AND HEAVY RAIN. A FEW SHOWERS WILL LINGER OVERNIGHT,
ESPECIALLY NORTH OF I-40 IN PROXIMITY TO A FRONT THAT IS CURRENTLY
NEAR THE TN/KY BORDER, BUT DO ANTICIPATE THAT THE LOW SEVERE
THREAT WILL WANE AFTER SUNSET. LOW CONFIDENCE IN FOG POTENTIAL
TONIGHT, ESPECIALLY WITH CLOUD COVER, BUT IF IT DOES DEVELOP, IT
WILL FAVOR AREAS THAT RECEIVED RAIN TODAY. ADDITIONAL STORMS
DEVELOP FRIDAY AFTERNOON AS THE AFOREMENTIONED FRONT TRACKS SOUTH
THROUGH MIDDLE TN.
SHORT TERM
(REST OF TODAY THROUGH SATURDAY)
ISSUED AT 1130 AM CDT THU SEP 10 2026
NORTHERN SECTIONS EXPERIENCED A FEW SHOWERS THIS MORNING WITH
REMNANTS OF STORMS THAT CAME FROM THE NORTHWEST OVERNIGHT.
ANOTHER DAY OF HOT AND HUMID CONDITIONS WILL HELP KICK OFF NEW
SHOWERS AND SCATTERED STORMS THIS AFTERNOON AND EVENING. THIS
ACTIVITY WILL OCCUR MOSTLY OVER THE NORTHWEST HALF OF OUR AREA AS
A WEAK FRONT DRAPES ALONG THE OHIO VALLEY. THERE WILL BE ENOUGH
CAPE (AROUND 2 KJ/KG) TO MAKE A FEW STRONG TO MARGINALLY SEVERE
STORMS FROM 2 PM TO 7 PM. LOCAL GUSTY WINDS AND HEAVY DOWNPOURS
WITH BRIEF FLOODING WILL BE THE MAIN CONCERNS. OTHERWISE, TEMPS
WILL REACH THE LOWER 90S FOR MOST AREAS, EXCEPT UPPER 80S PLATEAU.
MUGGY CONDITIONS WILL PUSH HEAT INDEX VALUES OVER 100, BUT MOSTLY
SHY OF HEAT ADVISORY LEVELS.
THE FRONT FROM THE OHIO VALLEY WILL DIP INTO THE MID STATE AND
STALL OUT ON FRIDAY, TRAPPING MIDDLE TN IN A MUGGY, UNSETTLED
REGIME. THE BOUNDARY ALONG WITH MID LEVEL SHORTWAVE DISTURBANCES
WILL BRING INCREASING COVERAGE OF SHOWERS AND STORMS, ESPECIALLY
FOR SATURDAY. THE INCREASED CLOUDINESS AND RAIN COVERAGE WILL
KEEP TEMPERATURES FROM BEING EXCESSIVELY HOT, BUT IT WILL STILL
BE VERY WARM AND HUMID. ENOUGH DIURNAL INSTABILITY WILL BE PRESENT
FOR ISOLATED STRONG STORM POTENTIAL, BUT PARAMETERS LIKE SHEAR
AND MID LEVEL LAPSE RATES LOOK UNIMPRESSIVE FOR ANY ORGANIZED
SEVERE STORM THREAT. PRECIPITABLE WATER VALUES WILL STAY HIGH
THROUGH SATURDAY, SO BRIEF, LOCAL FLOODING WILL BE POSSIBLE.
LONG TERM
(SATURDAY NIGHT THROUGH NEXT THURSDAY)
ISSUED AT 1130 AM CDT THU SEP 10 2026
AFTER SATURDAY, RAIN CHANCES WILL DROP OFF WITH GENERALLY LOW
CHANCES FOR SCATTERED SHOWERS AND STORMS IN THE AFTERNOON AND
EARLY EVENING HOURS EACH DAY NEXT WEEK. MODELS SHOW A STRONG MID
LEVEL RIDGE BUILDING UP AGAIN. THIS WILL PUMP UP THE HEAT WITH
SOME AREAS REACHING MIDDLE 90S AGAIN TUESDAY AND WEDNESDAY. MODELS
ARE SHOWING SIGNS OF RELIEF BY NEXT WEEKEND WITH POTENTIAL FOR A
FRONT DROPPING TEMPS DOWN TOWARD NORMAL LEVELS. THERE IS STILL A
WIDE SPREAD OF SOLUTIONS, BUT PROBABILITIES ARE TRENDING TOWARD
80S FOR HIGHS.
AVIATION
(00Z TAFS)
ISSUED AT 623 PM CDT THU SEP 10 2026
SCATTERED SHOWERS & THUNDERSTORMS HAVE DEVELOPED ACROSS MIDDLE TN
THIS AFTERNOON, BUT DO EXPECT THESE DIURNALLY-DRIVEN STORMS TO
DIMINISH AFTER SUNSET. LIGHT AND VARIABLE WINDS MAY CAUSE PATCHY
FOG RESULTING IN MVFR VIS IN SOME LOCATIONS TONIGHT. ANOTHER ROUND
OF SCATTERED STORMS DEVELOPS FRIDAY AS A FRONT MOVES INTO THE
AREA. LOW CONFIDENCE IN TIMING AND IF THERE WILL BE DIRECT IMPACTS
TO TERMINALS, BUT INTRODUCED ANOTHER PROB30 GROUP FOR MOST
TERMINALS THROUGH THE AFTERNOON WHEN STORM CHANCES ARE HIGHEST.
