..NEW UPDATE
KEY MESSAGES
UPDATED AT 728 PM CDT SUN JUL 5 2026
- OVERNIGHT, EXPECT VERY LITTLE RADAR ACTIVITY, BUT AREAS OF
RADIATION FOG ARE LIKELY TO DEVELOP OWING TO A WET GROUND, LIGHT
WIND AND NEAR-ZERO DEW POINT SPREADS.
- TYPICAL SUMMER-LIKE HEAT AND HUMIDITY ARE FORECAST FOR THE
UPCOMING WEEK. DAYTIME SHOWERS AND STORMS ARE EXPECTED FOR THE
NEXT SEVERAL DAYS, ESPECIALLY ON FRIDAY AND SATURDAY.
UPDATE
ISSUED AT 728 PM CDT SUN JUL 5 2026
EARLIER CONVECTION HAS MOSTLY DIED OFF AND VERY LITTLE ACTIVE
WEATHER IS EXPECTED THE REMAINDER OF THIS EVENING AND OVERNIGHT.
RAIN AND STORMS WILL PICK BACK UP DURING THE DAY TOMORROW, MAINLY
IN AREAS TO THE EAST AND SOUTH OF NASHVILLE, BUT THE RISK OF
SEVERE STORMS IS VERY LOW. THE ENVIRONMENT ACROSS MIDDLE TENNESSEE
THIS EVENING REMAINS MOIST AND UNSTABLE, BUT THERE IS A GREAT DEAL
LESS CONVECTION OCCURRING NOW THAN 24 HRS. AGO DUE TO THE
POSITIONING OF A SURFACE BOUNDARY THAT IS ALREADY MOST OF THE WAY
THROUGH MIDDLE TENNESSEE. SO THERE IS MUCH LESS FORCING AND
THEREFORE THE CELLS THAT ARE STILL OCCURRING SHOULD CONTINUE TO
DISSIPATE, LEAVING US WITH A HUMID NIGHT AND PLENTY OF RADIATION
FOG LATER ON, BUT REALLY NO APPRECIABLE RADAR ACTIVITY.
SHORT TERM
(REST OF TODAY THROUGH MONDAY)
ISSUED AT 1130 AM CDT SUN JUL 5 2026
WATER VAPOR IMAGERY AND RAP MESOANALYSIS DEPICT A BROAD UPPER-
LEVEL TROUGH ACROSS THE MISSISSIPPI VALLEY ALONG WITH TWO OR THREE
EMBEDDED VORTICITY MAXIMA/MCV FEATURES IN ARKANSAS AND MISSOURI
MOVING EAST. THESE DISTURBANCES WILL HELP INFLUENCE INCREASING
CONVECTIVE COVERAGE TODAY WITH UNSTABLE, MOIST AIR ALREADY IN
PLACE ACROSS MIDDLE TENNESSEE. THERE'S ENOUGH EFFECTIVE BULK SHEAR
TO HELP ORGANIZE STORMS INTO MULTICELL CLUSTERS/BOWING SEGMENTS
ALONG COLD POOLING. A DAMAGING WIND THREAT WILL PERSIST THIS
MORNING INTO THE EARLY EVENING, PARTICULARLY WITH ANY MORE ROBUST
UPDRAFTS/CORES ALOFT. THESE STRONGER STORMS WILL ALSO POSE A
THREAT FOR FREQUENT LIGHTNING AND SMALL HAIL ALONG WITH LOCALLY
HEAVY RAINFALL. ISOLATED FLOODING IS POSSIBLE WITH ANY SLOW-MOVING
STORMS DUE TO HIGH RAINFALL RATES. HIGH PWS ARE IN THE AREA,
GENERALLY 1.7" TO 2.0", NEAR AND EXCEEDING THE 90TH PERCENTILE.
DISTURBANCES ALOFT WILL REMAIN IN OUR REGION TOMORROW WITH
PERHAPS MORE AMPLIFICATION OF THE PRIMARY UPPER-LEVEL TROUGH TO
OUR WEST. THE COMBINATION OF FORCING ALOFT AND MOIST, UNSTABLE AIR
WILL LEAD TO ANOTHER DAY OF AT LEAST SCATTERED DAYTIME
CONVECTION. THERE'S NO OBVIOUS SIGNAL FOR SEVERE WEATHER, BUT ANY
MORE ROBUST STORM COULD PRODUCE DAMAGING WINDS AND FREQUENT
LIGHTNING, JUST AS TODAY. HEAT/HUMIDITY ARE BACK DOWN
INTO "TOLERABLE" LEVELS FOR SUMMERTIME TODAY AND TOMORROW.
LONG TERM
(MONDAY NIGHT THROUGH NEXT SUNDAY)
ISSUED AT 1130 AM CDT SUN JUL 5 2026
MID- TO UPPER-LEVEL TROUGHING IS FORECAST TO SLOWLY DRIFT EAST
ACROSS THE OHIO AND TENNESSEE VALLEYS TUESDAY AND WEDNESDAY.
ADDITIONAL DIURNAL CONVECTION IS FORECAST THAT WILL PERSIST INTO
MID WEEK WITH SOMEWHAT STEADY, PERSISTENT SUMMER-LIKE HEAT AND
HUMIDITY. THANKFULLY IT APPEARS SOME DRIER AIR WILL WORK INTO THE
REGION ON WEDNESDAY, SO OVERALL COVERAGE OF SHOWERS/STORMS IS
EXPECTED TO DECREASE MID WEEK. RAN/STORM CHANCE INCREASE AGAIN
LATE WEEK AS SUBSEQUENT DISTURBANCES/WEAK SURFACE FRONTS APPROACH
THE REGION IN THE LOW-AMPLITUDE PATTERN ALOFT.
AVIATION
