KEY MESSAGES
UPDATED AT 910 AM 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 TODAY AND TONIGHT)
ISSUED AT 910 AM CDT MON AUG 31 2026
UPPER LEVEL RIDGING WILL GRADUALLY PUSH EAST OVER THE TENNESSEE
VALLEY TODAY AND TUESDAY. MEANWHILE, SURFACE HIGH PRESSURE WILL
PERSIST OVER THE APPALACHIANS THROUGH THE WEEK. THIS PATTERN WILL
MAINTAIN LITTLE TO NO CHANCES OF SHOWERS/STORMS, SO THE HOT AND
HUMID CONDITIONS WILL BE THE MAIN CONCERN. HIGH TEMPERATURES ARE
FORECAST TO REACH THE LOWER TO MID 90S FOR MOST LOCATIONS, ALONG
WITH DEW POINTS IN THE UPPER 60S TO LOWER 70S. THIS WILL RESULT IN
HEAT INDICES REACHING BETWEEN 98-104 DEGREES THIS AFTERNOON,
ALONG WITH MOST AREAS IN A MODERATE HEATRISK (LEVEL 2 OF 4) AND
WBGTS IN THE MID TO UPPER 80S. ALL THIS TO SAY - PRACTICE HEAT
SAFETY, ESPECIALLY IF YOU WORK OUTSIDE OR HAVE OUTDOOR ACTIVITIES!
STAY HYDRATED, TAKE PLENTY OF BREAKS IN THE SHADE, AND NEVER
LEAVE PEOPLE OR PETS IN VEHICLES!
FOR TONIGHT EXPECT A WARM (LOWS IN THE LOWER 70S) AND CLEAR NIGHT
WITH CALM WINDS. THIS COULD BE CONDUCIVE FOR AT LEAST PATCHY
RIVER VALLEY FOG, BUT NOT ANTICIPATING WIDESPREAD FOG CONCERNS AT
THIS TIME.
SHORT TERM
(TUESDAY THROUGH WEDNESDAY NIGHT)
ISSUED AT 910 AM CDT MON AUG 31 2026
THE AFOREMENTIONED UPPER RIDGE PERSISTS THROUGH MIDWEEK, BUT THE
APEX WILL SHIFT TOWARDS THE APPALACHIANS DURING THIS TIME. SURFACE
HIGH PRESSURE CONTINUES AS WELL, HELPING LOCK IN THE HOT AND
HUMID CONDITIONS AND LITTLE TO NO RAIN CHANCES THROUGH THE SHORT
TERM. HIGHS ARE EXPECTED TO REACH THE MID TO UPPER 90S WITH LOWS
IN THE LOWER TO MID 70S FOR MOST AREAS. THESE TEMPERATURES, ALONG
WITH PERSISTENT DEW POINTS IN THE UPPER 60S TO LOWER 70S, WILL
CAUSE NWS HEATRISK TO INCREASE TO BE MAJOR BY WEDNESDAY (LEVELS 2
AND 3 OF 4) FOR MOST OF NORTH ALABAMA AND SOUTHERN MIDDLE
TENNESSEE. FORECAST HEAT INDICES REACH BETWEEN 100-106 ALONG WITH
WBGTS IN THE UPPER 80S TO AROUND 90 DEGREES. WE'LL CONTINUE TO
MONITOR IN CASE A HEAT ADVISORY BECOMES NECESSARY ON WEDNESDAY.
REGARDLESS, CAUTION SHOULD STILL BE EXERCISED, ESPECIALLY FOR
THOSE OUTDOORS. DRINK PLENTY OF WATER, FIND AREAS WITH AIR
CONDITIONING, AND NEVER LEAVE PEOPLE OR PETS IN CARS!
LONG TERM
(THURSDAY THROUGH SUNDAY)
ISSUED AT 755 PM CDT SUN AUG 30 2026
THE LONG TERM FORECAST WILL OFFER MORE OF THE SAME. AT THE SURFACE,
HIGH PRESSURE WILL DOMINATE, KEEPING TEMPS IN THE MID TO HIGH 90S
THROUGH THE WEEKEND. WITH RIDGING REMAINING IN PLACE IN THE MID
LEVELS TOO, OUR SAVING GRACE WILL BE THE FACT THAT OUR DEW POINTS
LOOK TO REMAIN IN THE HIGH 60S TO LOW 70S. THIS WILL LIMIT HOW HIGH
OUR HEAT INDICES CAN REACH WITH UNCERTAINTY REMAINING ON IF WE WILL
MEET HEAT ADVISORY CRITERIA. INVERSELY, SINCE WE WILL BE SLIGHTLY
DRIER, THERE IS SOME CONCERN FOR OVER PREFORMING ON CURRENT HIGH
TEMPERATURE FORECASTS. SOME DETERMINISTIC MODELS FLIRT WITH TRIPLE
DIGIT HIGHS THIS WEEKEND. WHILE WE HAVE LOW CONFIDENCE IN THIS
OCCURRING, IT WILL BE A TREND WE KEEP AN EYE ON. FROM SUNDAY FORWARD
THE FORECAST BECOMES SOMEWHAT MURKY. MODELS HAVE PICKED UP ON A
PASSING COLD FRONT YET ARE IN DISAGREEMENT ON WHEN AND IF IT COMES
THROUGH. IF THE COLD FRONT DOES MAKE IT THROUGH ON SUNDAY AS THE NBM
SUGGEST, HIGHS WILL DROP BACK TO THE LOW 90S. IF THE FRONT STALLS OR
DAMPENS BEFORE IT GETS HERE, HIGHS WILL LIKELY REMAIN IN THE HIGH 90S
THROUGH THE START OF THE NEXT WORK WEEK. MAKE SURE TO CONTINUE TO
PRACTICE PROPER HEAT SAFETY AND CHECK BACK FOR UPDATES.
