SHORT TERM
(TONIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 1020 PM CDT FRI AUG 21 2026
QUIET CONDITIONS ARE EXPECTED TO PREVAIL TONIGHT WITH THE ONLY
CONCERN BEING FOG. MOSTLY CLEAR SKIES AND LIGHT WINDS WILL BE
SUPPORTIVE FOR FOG OVERNIGHT. HIGHEST CONFIDENCE IN FOG IS ACROSS
THE PLATEAU, AND SHORT-TERM MODELS SUPPORT THIS AS WELL WITH ONLY
LOW PROBABILITY OF 10-20% FOR FOG WEST OF THE PLATEAU. UPPER-LEVEL
TROUGHING REMAINS IN PLACE OVER THE EASTERN CONUS SATURDAY, AND A
WEAK FRONT WILL ALLOW FOR ISOLATED THUNDERSTORMS TO DEVELOP DURING
THE AFTERNOON, MAINLY FOR AREAS NEAR THE TN/AL BORDER AND ACROSS
THE PLATEAU. OTHERWISE, IT'LL BE A FAIRLY NICE SATURDAY WITH MOST
OF THE AREA STAYING DRY AND SEASONABLE TEMPERATURES IN THE
UPPER-80S TO LOW-90S. UPPER-LEVEL TROUGHING CONTINUES INTO SUNDAY
AND BEHIND THE FRONT, SUNDAY PROMISES TO BE A VERY NICE DAY WITH
DRY CONDITIONS AND SLIGHTLY COOLER TEMPERATURES IN THE MID TO
UPPER-80S.
LONG TERM
(MONDAY THROUGH NEXT SATURDAY)
ISSUED AT 1020 PM CDT FRI AUG 21 2026
SLIGHTLY BELOW NORMAL TEMPERATURES CONTINUE INTO MONDAY, BUT THE
AFOREMENTIONED TROUGH MOVES EAST BY TUESDAY. WITH RIDGING TO THE
WEST, NORTHWEST FLOW SETS UP OVER MIDDLE TN THROUGH THE END OF THE
WEEK. TEMPERATURES WILL WARM A FEW DEGREES, BUT WILL STILL BE
SEASONABLY NORMAL. NORTHWEST FLOW ALSO ALLOWS FOR DAILY LOW TO
MEDIUM RAIN & THUNDERSTORM CHANCES TO RETURN TUESDAY THROUGH THE
END OF THE WEEK.
