NEAR TERM
(TODAY)
ISSUED AT 150 AM CDT TUE OCT 13 2026
CLEAR SKIES AND CALM WINDS WILL PRESENT ANOTHER IDEAL NIGHT FOR
RADIATIONAL COOLING WITH LOWS LIKELY DIPPING INTO THE MID TO LOW
50S ACROSS THE AREA. DON'T LET THE COOL MORNING FOOL YOU, WITH
HIGH PRESSURE BUILDING BOTH AT THE SURFACE AND ALOFT, HIGH WILL
SOAR SEVERAL DEGREES ABOVE NORMAL AGAIN TODAY. IN FACT, WE HAVE A
PRETTY GOOD SHOT AT TYING OR BREAKING HIGH TEMPERATURE RECORDS
FOR OCTOBER 13TH TODAY. THE STANDING RECORD AT MSL IS 91, WITH THE
RECORD AT HSV BEING 89. CURRENTLY THE FORECAST HIGHS ARE 90 AND
89 RESPECTIVELY. FORTUNATELY THE SUMMER LIKE HEAT IS NOT MET WITH
SUMMER LIKE HUMIDITY. DEW POINTS WILL REMAIN IN THE 60S WITH A
MEDIUM CHANCE OF MIXING DOWN INTO THE HIGH 50S THIS AFTERNOON
THANKS TO VERY DRY AIR ALOFT.
SHORT TERM
(TUESDAY NIGHT THROUGH THURSDAY)
ISSUED AT 940 PM CDT MON OCT 12 2026
A LARGE AREA OF HIGH PRESSURE WILL ROTATE OVER THE DEEP SOUTH
WEDNESDAY AND THURSDAY, CONTINUED WARM/SUNNY CONDITIONS WILL
PERSIST THROUGH MUCH OF THE WORK WEEK. AMPLE SUNSHINE AND LIGHT
SOUTHERLY WINDS WILL AGAIN HELP PUSH HIGH TEMPERATURES INTO THE
UPPER 80S TO LOWER 90S IN MOST LOCATIONS BOTH DAYS, WITH LOWS
REMAINING IN THE LOW TO MID 60S. THE SOUTHERLY WINDS WILL ALSO
HELP ADVECT MOISTURE INTO THE AREA, AS EVIDENCED BY DEWPOINTS
CLIMBING INTO THE MID TO UPPER 60S. COMBINED WITH TEMPERATURES IN
THE LOWER 90S, THIS WILL PUSH HEAT INDEX VALUES IN THE LOW TO MID
90S AND POTENTIALLY CREATE SOME MODERATE (LEVEL 2/4) HEAT IMPACTS
BOTH DAYS. THESE HIGH TEMPERATURES ARE WELL ABOVE THE SEASONAL
NORM, SO CONTINUE PRACTICING HEAT SAFETY IF YOU HAVE OUTDOOR
PLANS!
LONG TERM
(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 940 PM CDT MON OCT 12 2026
A STRONG UPPER TROUGH OVER THE GREAT LAKES WILL PUSH A STRONG COLD
FRONT INTO THE OHIO AND TENNESSEE VALLEYS THURSDAY NIGHT INTO
FRIDAY. NOT ANTICIPATING MUCH IN THE WAY OF RAIN CHANCES WITH
THIS FEATURE, BUT SOME ADDED CLOUD COVER MAY ACCOMPANY IT AS IT
PASSES THROUGH THE AREA. THE MAIN IMPACT WILL BE THE BREEZY
CONDITIONS THAT WILL BE OBSERVED ON FRIDAY WITH THE PASSAGE OF THE
FRONT AND MUCH COOLER AND DRIER AIR MASS THAT WILL ADVECT INTO
THE AREA IN ITS WAKE. HIGHS ON FRIDAY (THE TRANSITION DAY) WILL
RUN ABOUT 10 DEGREES LOWER THAN WEDNESDAY/THURSDAY (HIGHS IN THE
LOWER 80S), BUT A STRONG PUSH OF COOLER AIR WILL OCCUR OVERNIGHT
AS LOWS WILL DROP LIKE A ROCK INTO THE MID TO UPPER 40S BY EARLY
SATURDAY MORNING. THIS AUTUMN-LIKE AIR MASS WILL TAKE HOLD ON
SATURDAY AS HIGHS IN THE UPPER 60S WILL BE COMMON ON SATURDAY AND
THE UPPER 60S TO LOWER 70S ON SUNDAY (WITH LOWS IN THE 40S). AS
RIDGING BUILDS IN, A GRADUAL WARMING TREND WILL TAKE PLACE AS
HIGHS RETURN TO THE MID TO UPPER 70S BY MONDAY.
