SHORT TERM
(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 1030 PM CDT SAT AUG 29 2026
AN UPPER LEVEL RIDGE THAT WAS PLACED OVER THE FOUR CORNERS REGION
HAS STARTED TO PUSH EAST. THIS WILL CONTINUE TO BUILD OVER THE
SOUTHEAST US THIS WEEK AND WILL BRING AN EXTENDED PERIOD OF MAINLY
DRY WEATHER ALONG WITH HOT TEMPERATURES. HIGHS ON SUNDAY WILL BE A
DEGREE OR TWO WARMER THAN WHAT WE SAW SATURDAY WITH MID 90S BEING
MORE WIDESPREAD ACROSS THE AREA. DEW POINTS WILL ALSO BE A BIT
HIGHER IN THE LOW TO MID 70S. SOME AFTERNOON CUMULUS CLOUDS CAN BE
EXPECTED BUT NO RAIN OR THUNDERSTORMS. THE FORECAST WON'T CHANGE
MUCH AS WE HEAD INTO THE WORK WEEK AS THE RIDGE CONTINUES TO BUILD
OVER THE REGION. HIGHS WILL BE IN THE LOW TO MID 90S WITH
AFTERNOON HEAT INDEX VALUES AROUND 100.
LONG TERM
(TUESDAY THROUGH NEXT SUNDAY)
ISSUED AT 1030 PM CDT SAT AUG 29 2026
THE RIDGE WILL BE CENTERED OVER MIDDLE TN BY THE MIDDLE OF THE
WEEK WITH HIGHS CONTINUING TO GO UP A FEW DEGREES. WE SHOULD SEE
MID TO UPPER 90S BY WEDNESDAY WITH HEAT INDEX VALUES AS HOT AS
107. WITH THE PROLONGED PERIOD OF HOT TEMPERATURES WE WILL SEE
MAJOR HEAT RISK BY TUESDAY AND MAJOR TO EXTREME HEAT RISK BY
WEDNESDAY. OVERNIGHT LOWS WILL ALSO BE MILD THROUGHOUT THE WEEK
ONLY FALLING INTO THE 70S. AN UPPER LEVEL TROUGH WILL PUSH INTO
THE NORTHEAST LATE WEEK INTO NEXT WEEKEND AND THAT WILL HELP TO
FLATTEN THE RIDGE AND BUILD IT BACK WEST BUT THERE IS SOME
UNCERTAINTY WITH THAT. THAT WILL INFLUENCE IF WE COOL OFF SOME OR
NOT. WITH THE RIDGE OVERHEAD OUR RAIN CHANCES WILL BE LITTLE TO
NONE FOR MUCH OF THE WEEK. LOW RAIN CHANCES ENTER THE FORECAST
LATE IN THE WEEK BUT WILL BE DEPENDENT ON HOW THE RIDGE BREAKS
DOWN.
