KEY MESSAGES
UPDATED AT 850 PM CDT FRI AUG 28 2026
- DANGEROUS HEAT WILL RETURN EARLY NEXT WEEK AND WILL TEND TO
INTENSIFY THROUGH THE WEEK WITH HEAT INDICES APPROACHING OR
EXCEEDING 100 DEGREES.
- THERE ARE LOW CHANCES FOR THUNDERSTORMS EACH DAY MAINLY FROM
SUNDAY AFTERWARD, AND ESPECIALLY IN HIGHER TERRAIN AREAS DURING
THE AFTERNOONS.
NEAR TERM
(REST OF TONIGHT AND SATURDAY)
ISSUED AT 850 PM CDT FRI AUG 28 2026
MOSTLY CLEAR SKIES AND LIGHT WINDS HAVE PREVAILED THIS EVENING AS
CURRENT SATELLITE SHOWS AN AXIS OF HIGHER MOISTURE POSITIONED TO
OUR SOUTHEAST AND ONLY A FEW MID TO HIGH CLOUDS DRIFTING OVER THE
AREA. DRY CONDITIONS ARE FORECAST TONIGHT WITH A LOW CHANCE FOR
PATCHY FOG MAINLY IN SHELTERED AND RIVER VALLEY AREAS ACROSS NE AL
AND SOUTHERN MIDDLE TN. OVERNIGHT LOWS WILL FALL TO THE MID TO
UPPER 60S, MAKING IT THE COOLEST NIGHT IN THE 7 DAY FORECAST.
ENJOY THE "NICER" TEMPERATURES TONIGHT BEFORE OUR NEXT HEAT WAVE
MOVES IN!
HIGH PRESSURE WILL REMAIN DOMINANT AMID AN AMPLIFYING UPPER RIDGE
LEADING TO DRY BUT WARMING CONDITIONS AS WE HEAD THROUGH THE
WEEKEND. HIGHS TOMORROW WILL TOP OUT IN THE LOW TO MID 90S WITH
THE WARMEST TEMPERATURES EXPECTED WEST OF I-65. WITH LIMITED
MOISTURE, EXPECT FEW TO SCATTERED DIURNAL CU BUT STILL PLENTY OF
SUNSHINE FOR THOSE SPENDING TIME OUTDOORS. BE SURE TO WEAR LIGHT,
BREATHABLE CLOTHING AND STAY HYDRATED WHEN SPENDING TIME OUT IN
THE HEAT.
SHORT TERM
(SATURDAY NIGHT THROUGH MONDAY)
ISSUED AT 850 PM CDT FRI AUG 28 2026
THE SHORT TERM FORECAST WILL CHANGE LITTLE AS THE SYNOPTIC PATTERN
FAVORS A STRONG UPPER HIGH/RIDGING CENTERING CLOSER TO THE REGION.
AS H85 HEIGHTS RISE, SO WILL OUR TEMPERATURES EACH DAY WITH MID
90S HIGHS BECOMING MORE WIDESPREAD OVER THE AREA. THE GOOD NEWS IS
THAT THE SOUTHERLY GULF FETCH IS NOT AS STRONG WITH THIS WAVE AND
MOISTURE/HUMIDITY WILL NOT BE QUITE AS HIGH. THIS WILL KEEP
THUNDERSTORM CHANCES CAPPED AT 20-30% OR BELOW EACH DAY, MAINLY
OVER NE AL. HEAT INDICES WILL CLIMB TO THE 99-105 DEGREE RANGE
WHICH WILL POSE A RISK FOR HEAT RELATED ILLNESS ESPECIALLY FOR
THOSE MORE SUSCEPTIBLE TO HEAT. RIGHT NOW THE COVERAGE OF HEAT
INDICES AT OR ABOVE 105 DEGREES LOOKS A BIT MORE LIMITED AND WE
HAVE NO CURRENT PLANS TO ISSUE ANY HEAT ADVISORIES, BUT THAT COULD
CHANGE AS WE GET CLOSER TO NEXT WEEK. BE SURE TO STAY TUNED FOR
UPDATES AND ALWAYS FOLLOW HEAT SAFETY GUIDELINES!
LONG TERM
(MONDAY NIGHT THROUGH FRIDAY)
ISSUED AT 850 PM CDT FRI AUG 28 2026
BY THE START OF THE LONG TERM, RIDGING WILL BE CENTERED OVER THE
TN VALLEY. THIS WILL BE PAIRED WITH HIGH PRESSURE OVER THE EASTERN
CONUS AT THE SURFACE. THE HIGH PRESSURE WILL WORK TO KEEP RAIN
CHANCES LOW AND SET TEMPS ON A WARMING TREND. HIGHS LOOK TO WARM
FROM THE LOW 90S BACK TO THE HIGH 90S BY THE END OF THE WEEK.
SURFACE HIGH PRESSURE WILL INDUCE WEAK ESE FLOW WHICH WILL
GRADUALLY RETURN DEW POINTS TO THE 70S. WHILE WE WILL HAVE TO KEEP
AND EYE ON TRENDS, MODELS CURRENTLY KEEP DEW POINTS IN THE LOW
70S WHICH WILL WORK IN OUR FAVOR TO KEEP HEAT INDICES BELOW HEAT
ADVISORY CRITERIA (105F). UNDER ESE FLOW, DEW POINTS LOOK HIGHEST
IN NE AL. AS SUCH, LOW CHANCES (20% OR LESS) FOR TERRAIN ENHANCED
SHOWERS ARE FORECAST EACH AFTERNOON. WITHOUT ANY WIDESPREAD
FORCING FOR CLOUDS AND RAIN, HEAT WILL BE OUR PRIMARY CONCERN
THROUGH THE LONG TERM FORECAST. MAKE SURE TO CHECK BACK FOR
UPDATES AND CONTINUE TO PRACTICE PROPER HEAT SAFETY.
