KEY MESSAGES
ISSUED AT 1144 PM CDT SAT AUG 8 2026
- SUMMER PATTERN: SCATTERED SHOWERS AND THUNDERSTORMS WILL PERSIST
THROUGH THE WEEKEND, WITH LOCALLY HEAVY RAINFALL LIKELY UNDER
HIGH MOISTURE AND SLOW-MOVING STORMS.
- HEAT: HUMIDITY WILL PUSH HEAT INDICES INTO THE 97-104 DEGREE
RANGE THIS WEEKEND INTO NEXT WEEK, RESULTING IN A MODERATE HEAT
RISK ACROSS CENTRAL ALABAMA.
DISCUSSION
(SUNDAY THROUGH NEXT SATURDAY)
ISSUED AT 1144 PM CDT SAT AUG 8 2026
THIS EVENING, CENTRAL ALABAMA REMAINS IN A SOMEWHAT WEAK UPPER
FLOW AREA SOUTH OF THE MAIN BROAD TROUGH THAT EXTENDS OUT OF
CENTRAL CANADA AND DOWN INTO THE GREAT LAKES. AT THE SAME TIME,
ALABAMA IS SITUATED BETWEEN TWO RIDGES, ONE ACROSS THE FOUR
CORNERS AND THE OTHER IN THE WESTERN ATLANTIC OFF OF THE FL COAST
ALONG WITH A WEAK, SMALL SHORTWAVE FROM THE MAIN UPPER TROUGH JUST
TO OUR NW. THIS WILL NOT MAKE A BIG DIFFERENCE AS IT PROPAGATES
EWD ACROSS THE SE US AS IT REMAINS WEAK. OUR EMPHASIS WILL STILL
BE TYPICAL SUMMERTIME DIURNALLY ENHANCED CONVECTION OVERALL. BY
MONDAY, THE WESTERN ATLANTIC RIDGE FLATTENS AND RETROGRADES
FURTHER WESTWARD ACROSS THE NORTHERN GULF COAST. AT THE SAME TIME,
IT ALSO SHOWS THE UPPER SHORTWAVE ABSORBED BACK INTO THE LONGWAVE
TROUGH WITH CONTINUED SUMMERTIME DIURNALLY ENHANCED ACTIVITY
EXPECTED THROUGH THE REMAINDER OF THE WEEK.
AS FOR TEMPERATURES, READINGS VARY ONLY A DEGREE OR SO HERE AND
THERE THROUGH MID WEEK WITH OVERALL MOISTURE REMAINING UP. THIS
WILL RESULT IN MAX AFTERNOON HEAT INDICES PERHAPS A COUPLE OF
DEGREES HIGHER IN SPOTS. HOWEVER, GUIDANCE CONTINUES TO KEEP US
BELOW HEAT ADVISORY CRITERIA FOR NOW. WE WILL BE WATCHING AS WE
HEAD INTO THE END OF THE WEEK WITH A MEDIUM CHANCE OF THE UPPER
RIDGE BUILDING INTO AND GETTING STRONGER ACROSS THE SE US AND
TEMPERATURES WARMING FURTHER. THIS COULD INCH US BACK CLOSER TO
HEAT ADVISORY CRITERIA BY FRIDAY INTO NEXT WEEKEND.

AVIATION
(00Z TAFS)
ISSUED AT 719 PM CDT SAT AUG 8 2026
DIURNAL SHOWER AND THUNDERSTORM ACTIVITY WILL CONTINUE TO PERSIST
OVER THE NEXT FEW HOURS THANKS TO SOME OUTFLOW BOUNDARY INTERACTIONS
ACROSS THE NORTHERN HALF OF THE AREA. WILL CONTINUE TO MENTION
PROB30S FOR TCL/BHM/EET THROUGH 3Z. OTHERWISE, OUTSIDE OF CONVECTION,
WINDS ARE EXPECTED TO BE LIGHT AND VARIABLE OVERNIGHT. THERE IS A
MEDIUM CHANCE FOR MVFR VSBYS IN A FEW SPOTS. I HAVE TEMPOS FOR EET/
AUO TOWARD SUNRISE AT THIS TIME. WITH WEAK RIDGING CENTERED TO THE
EAST, WINDS WILL GENERALLY CONTINUE TO BE LIGHT AND VARIABLE DURING
THE DAY, BUT COULD BE AS HIGH AS 3-7KTS FROM THE E/SE ON SUNDAY
AFTERNOON IN A FEW SPOTS. MORE TYPICAL SUMMERTIME DIURNAL CONVECTION
IS EXPECTED ON SUNDAY AFTERNOON.
NOTE: AMD NOT SKED FOR AUO DUE TO A WEATHER OBSERVATION OUTAGE.
08
FIRE WEATHER
WARM AND HUMID CONDITIONS WILL HELP KEEP MINRH VALUES GENERALLY
ABOVE 50% THROUGH THE WEEK. ISOLATED TO SCATTERED SHOWERS AND
STORMS ARE EXPECTED DAILY. BECAUSE OF THIS, ELEVATED FIRE WEATHER
CONCERNS WILL REMAIN LOW OVER THE NEXT SEVEN DAYS.
