SHORT TERM
(THIS AFTERNOON THROUGH WEDNESDAY NIGHT)
ISSUED AT 1216 PM CDT TUE AUG 18 2026
A MUCH MORE COMFORTABLE DAY HAS PLAYED OUT ACROSS MIDDLE TN TODAY.
OUR WEATHER IS COOLER BEHIND YESTERDAY'S FRONTAL PASSAGE AS HIGH
TEMPERATURES TOP OUT IN THE 80S AND LOW 90S UNDER MOSTLY SUNNY
SKIES. TONIGHT'S LOW TEMPERATURES BOTTOM OUT IN THE UPPER 60S FOR
MOST LOCATIONS UNDER MOSTLY CLEAR SKIES. ON WEDNESDAY, SOUTHERLY
RETURN FLOW WILL ALLOW OUR TEMPERATURES TO WARM BACK INTO THE MID
90S. INCREASING HUMIDITY ACCOMPANIES THE WARMER TEMPERATURES AS OUR
SURFACE DEW POINTS CREEP BACK INTO THE 70S, TOO. OUR HEAT INDICES
WILL REFLECT THE RETURN OF WARMER, MORE HUMID WEATHER AS THEY TOP
OUT IN THE UPPER 90S AND LOWER 100S WEDNESDAY AFTERNOON. WEDNESDAY
NIGHT WILL BEGIN TO SEE A SHIFT AS AN APPROACHING SYSTEM USHERS IN
CLOUD COVER OVERNIGHT. RAIN AND STORM CHANCES RETURN BY THURSDAY
MORNING.
LONG TERM
(THURSDAY THROUGH NEXT TUESDAY)
ISSUED AT 1216 PM CDT TUE AUG 18 2026
ON THURSDAY, AN APPROACHING COLD FRONT WILL MAINTAIN RAIN/STORM
CHANCES THROUGHOUT THE MORNING HOURS. GUIDANCE SUGGESTS THE
POTENTIAL THAT A FEW STORMS COULD BECOME STRONG TO SEVERE WITH THE
PRIMARY CONCERN BEING STRONG/GUSTY WINDS AND HEAVY RAINFALL. THE
OVERALL SEVERE WEATHER CHANCES ARE LOW, BUT NON-ZERO. THE FRONT WILL
SHIFT TO THE EAST BY MID-AFTERNOON, WHICH WILL ALLOW DRIER AIR INTO
MIDDLE TN THURSDAY EVENING. TROUGHING AND NORTHWEST FLOW WILL
SUPPORT ADDITIONAL SHOWER CHANCES FRIDAY AFTERNOON. FORTUNATELY, THE
COVERAGE SHOULD REMAIN RATHER ISOLATED TO SCATTERED AT BEST. THIS
WEEKEND LOOKS PRIMARILY DRY, BUT ISOLATED SHOWERS CANNOT BE RULED
OUT. TEMPERATURES APPEAR TO STAY MUCH MORE SEASONABLE THROUGH THE
WEEKEND AND INTO EARLY NEXT WEEK. GUIDANCE SUPPORTS HIGH PRESSURE
SETTLING IN THAT SHOULD LIMIT ANY WIDESPREAD PRECIPITATION. A
WELCOMED CHANGE COMPARED TO THE RECENT WARMTH.
