DISCUSSION
(TONIGHT THROUGH NEXT SUNDAY)
ISSUED AT 1155 PM CDT SUN JUL 26 2026
8PM RADAR IMAGERY DEPICTS A COMPLEX OF STORMS DIVING SOUTH OUT OF
KENTUCKY INTO MIDDLE TENNESSEE. THE 00Z SOUNDING OUT OF NASHVILLE
DEPICTS SURFACE CAPE GREATER THAN 4500 J/KG ALONG WITH BULK SHEAR
NEARING 30 KTS. WHILE SHEAR IS ON THE WEAKER SIDE, THE ABUNDANCE
OF INSTABILITY WILL BE ENOUGH FOR STORMS TO OVERCOME THE WEAKER
KINEMATICS. ONE THING TO NOTE ON THE SOUNDING IS A WEAK EML AT
AROUND 750 MB. THE CAMS ARE MODELING THIS WELL, DEPICTING
INCREASING CIN OVER THE NEXT SEVERAL HOURS. GIVEN THIS, STORMS
WILL STRUGGLE TO MAINTAIN STRENGTH FOR LONG AND LIKELY DIMINISH
BY MIDNIGHT. DAMAGING WINDS AND HEAVY RAINFALL ARE THE PRIMARY
CONCERNS AT THIS TIME.
HOT AND HUMID CONDITIONS RESUME ON MONDAY AS THE EASTERN FLANK OF
A 598 DAM RIDGE REMAINS OVER THE MID-SOUTH. AFTERNOON HIGHS WILL
REACH THE UPPER 90S AREAWIDE WITH HEAT INDICES IN EXCESS OF
110 DEGREES. THIS PATTERN WILL PERSIST INTO TUESDAY AS
TEMPERATURES APPROACH 100 DEGREES. AN EXTREME HEAT WARNING AND
HEAT ADVISORY ARE IN EFFECT THROUGH 8PM TUESDAY. LUCKILY, A
BACKDOOR COLD FRONT WILL SWING THROUGH THE MID-SOUTH ON WEDNESDAY
AND DECREASE DEWPOINTS INTO THE 60S. THIS WILL PRODUCE HEAT
INDICES BENEATH HEADLINE CRITERIA BY THURSDAY. UNTIL THEN, MAKE
SURE YOU MONITOR YOURSELF FOR SIGNS OF HEAT-RELATED ILLNESS IF
WORKING OUTDOORS. TAKE FREQUENT BREAKS AND REMEMBER TO DRINK
PLENTY OF WATER.
BY FRIDAY, A SHORTWAVE TROUGH WILL MOVE THROUGH THE CENTRAL
PLAINS. THIS FEATURE WILL INCREASE RAIN CHANCES IN THE MID-SOUTH
THROUGH THE WEEKEND. IT REMAINS TOO EARLY TO TELL SPECIFICS, BUT
FOR NOW EXPECT THE UPCOMING WEEKEND TO BE WET AND UNSETTLED.

AVIATION
(06Z TAFS)
ISSUED AT 1155 PM CDT SUN JUL 26 2026
TSRA REMAINED EAST OF THE TERMINALS THIS EVENING. WHILE PATCHY
FOG MAY BRIEFLY IMPACT TUP AND MKL OVERNIGHT, VFR CONDITIONS WILL
OTHERWISE PREVAIL UNDER A LIGHT SOUTH/SOUTHWEST FLOW. WINDS WILL
INCREASE SLIGHTLY DURING THE DAY BUT REMAIN UNDER 10 KTS.
CONFIDENCE IS LOW REGARDING ANOTHER MCV TRACKING SOUTH TOMORROW
AFTERNOON/EVENING, BUT IF IT DEVELOPS, MKL WOULD SEE THE HIGHEST
POTENTIAL IMPACTS FROM TSRA.

FIRE WEATHER
ISSUED AT 1155 PM CDT SUN JUL 26 2026
NO MAJOR FIRE DANGER CONCERNS FOR THE FORESEEABLE FUTURE AS MINRH
VALUES REMAIN ABOVE 40% AND 20FT WINDS STAY BELOW 10 MPH.
