KEY MESSAGES
UPDATED AT 840 PM CDT MON AUG 31 2026
- HOT AND HUMID CONDITIONS TO PERSIST THROUGH NEXT WEEKEND, WITH
MODERATE TO MAJOR HEATRISK ALONG WITH AFTERNOON HEAT INDICES
RISING TO BETWEEN 100-106 DEGREES.
NEAR TERM
(REST OF TONIGHT AND TUESDAY)
ISSUED AT 840 PM CDT MON AUG 31 2026
THE BIGGEST FEATURE OF THE NEAR TERM WILL BE THE OVERNIGHT LOWS.
UNDER CLEAR SKIES AND CALM WINDS, TEMPS WILL DROP TO THE LOW TO
MID 70S. THESE WILL BE SOME OF THE COOLEST TEMPERATURES OF THE
ENTIRE WEEK SO MAKE SURE TO ENJOY IT NO MATTER HOW MUGGY TUESDAY
MORNING FEELS.
THROUGH THE DAY ON TUESDAY HIGH PRESSURE BOTH AT THE SURFACE AND
ALOFT WILL PROMOTE CLEAR SKIES AND CALM WINDS. OUR MID LEVEL
RIDGING WILL BUILD SLIGHTLY EAST, NEARLY CENTERING US UNDER THE
RIDGE. THIS WILL WORK TO BUMP TEMPERATURES UP A FEW DEGREES WITH
HIGHS BREAKING INTO THE MID TO HIGH 90S. DESPITE THE HIGHER TEMPS,
DEW POINTS LOOK TO REMAIN IN THE LOW 70S. THIS WILL WORK TO KEEP
HEAT INDICES SLIGHTLY LOWER WITH MOST LOCATIONS STAYING UNDER
105F. SOME URBAN LOCATIONS MAY SEE 105F+ HEAT INDICES HOWEVER
THIS IS NOT FORECAST TO BE WIDESPREAD ENOUGH TO WARRANT ANY HEAT
PRODUCT ISSUANCES. NONETHELESS, HEAT WILL BE A CONCERN WITH OR
WITHOUT HEAT HEADLINE SO PLEASE MAKE SURE TO CONTINUE TO PRACTICE
PROPER HEAT SAFETY. OTHERWISE, AS WITH THE LAST FEW DAYS, LOW
CHANCES FOR SHOWERS WILL AGAIN BE FORECAST TUESDAY AFTERNOON
ACROSS THE AREA.
SHORT TERM
(TUESDAY NIGHT THROUGH THURSDAY NIGHT)
ISSUED AT 840 PM CDT MON AUG 31 2026
THROUGH THE SHORT TERM PERIOD MID LEVEL RIDGING WILL CONTINUE TO
BUILD OVER THE TN VALLEY. THIS WILL CONTINUE OUR WARMING TREND
WITH HIGHS IN THE UPPER 90S EACH AFTERNOON. WITHOUT ANY PROMINENT
PATTERN CHANGES DEW POINTS WILL REMAIN UNCHANGED WITH EACH
AFTERNOON SEEING VALUES IN THE LOW TO MID 70S. WHILE THESE LOWER
DEW POINTS WILL KEEP US FROM WIDESPREAD OPPRESSIVE HEAT, HEAT
INDICES DO LOOK TO NUDGE OVER 105 BY THURSDAY. THERE IS CURRENTLY
UNCERTAINTY REGARDING HOW WIDE SPREAD THESE VALUES WILL BE SEEN
ACROSS THE AREA, THUS HEAT PRODUCT DECISIONS ARE LIKELY STILL
24-48 HOURS OUT. REGARDLESS OF HEAT HEADLINE DECISIONS, IT WILL BE
IMPORTANT FOR THOSE PARTAKING IN OUTDOOR ACTIVITIES TO CONTINUE TO
PRACTICE PROPER HEAT SAFETY.
LONG TERM
(FRIDAY THROUGH MONDAY) I
ISSUED AT 840 PM CDT MON AUG 31 2026
NOT MUCH CHANGE IS EXPECTED IN THE OVERALL WEATHER PATTERN AS WE HEAD
THROUGH THE LONG TERM PERIOD. DANGEROUS HEAT CONTINUES TO BE A THREAT
THROUGH AT LEAST SUNDAY WITH HEAT RISK FORECAST TO REMAIN AT MODERATE
(LEVEL 2 OF 4) TO MAJOR (LEVEL 3 OF 4). THE UPPER LEVEL RIDGE
REMAINS ENTRENCHED OVER THE CENTRAL AND SOUTHEASTERN US WITH HIGH
PRESSURE DOMINANT UNDERNEATH. AS A RESULT, HOT AND DRY CONDITIONS
CONTINUE THROUGH THE WEEKEND. WHILE WE CANNOT RULE OUT A LOW (10-20%)
CHANCE OF AN ISOLATED THUNDERSTORM EACH AFTERNOON, CONFIDENCE IS
QUITE LOW IN THIS OCCURRING AND MOST LOCATIONS WILL LIKELY REMAIN
DRY. AFTERNOON HIGHS EACH AFTERNOON WILL RISE INTO THE MID TO UPPER
90S WITH HEAT INDICES BETWEEN 100-105F. THE DOME OF HIGH PRESSURE
BEGINS TO RECEDE BACK TO THE WEST ON MONDAY, WHICH WILL PROVIDE SOME
RELIEF TO THE HEAT WITH AFTERNOON HIGHS ONLY IN THE LOWER 90S.
HOWEVER, MODELS CONTINUE TO TREND LATER WITH THIS OCCURRING AND IT
WILL BE SOMETHING WE WILL WATCH AS WE GET CLOSER IN TIME.
