DISCUSSION
(TONIGHT THROUGH NEXT WEDNESDAY)
ISSUED AT 1113 PM CDT WED JUL 23 2025
LATE EVENING TEMPERATURES ACROSS THE MIDSOUTH ARE STILL IN THE 90S
AT A FEW LOCATIONS WITH MOST OF THE REGION IN THE MIDDLE TO UPPER
80S. MOST OF US WILL SEE SUNRISE TEMPERATURES IN THE MIDDLE TO
UPPER 70S, ALTHOUGH IT IS POSSIBLE THAT PORTIONS OF THE MEMPHIS
METRO MAY NOT FALL BELOW 80 DEGREES. THE 596 DAM RIDGE WHICH HAS
BEEN PLAGUING US FOR A WEEK OR SO REMAINS IN PLACE AND WILL RESULT
IN ANOTHER VERY HOT DAY TODAY. HIGH TEMPERATURES WILL LIKELY BE IN
THE MIDDLE TO UPPER 90S ONCE AGAIN WITH DEW POINTS IN THE MIDDLE
TO UPPER 70S. AN EXTREME HEAT WARNING HAS BEEN ISSUED FOR MUCH OF
THE MIDSOUTH TODAY THROUGH EARLY EVENING. THE EXCEPTION IS NEAR
THE TENNESSEE RIVER IN WEST TENNESSEE AND IN PORTIONS OF NORTHEAST
MISSISSIPPI WHERE A BACKDOOR COLD FRONT SHOULD KEEP TEMPERATURES
SLIGHTLY COOLER. HOWEVER, THOSE LOCATIONS ARE STILL INCLUDED IN A
HEAT ADVISORY. EXPECT AFTERNOON HEAT INDICES BETWEEN 103 AND 114
ACROSS THE MIDSOUTH. HEAT PRODUCTS WILL LIKELY BE NEEDED FRIDAY
AND THROUGH THE WEEKEND FOR PORTIONS OF THE AREA. STAY AHEAD OF
THE HEAT BY HYDRATING EARLY AND OFTEN, TAKING FREQUENT BREAKS IN
THE AC, AND AVOIDING STRENUOUS ACTIVITY DURING THE HOTTEST PART OF
THE DAY.
THE RIDGE IS EXPECTED TO WEAKEN AND SHIFT SLIGHTLY EASTWARD OVER
THE WEEKEND, BUT UNFORTUNATELY IT LOOKS TO STRENGTHEN AND SHIFT
BACK OVER THE MIDDLE MISSISSIPPI RIVER VALLEY EARLY NEXT WEEK.
TEMPERATURES MONDAY THROUGH WEDNESDAY OF NEXT WEEK LOOK JUST AS
HOT, IF NOT A BIT HOTTER AS WE HAVE SEEN FOR THE PAST FEW DAYS.
EXPECT ADDITIONAL EXTREME HEAT WARNINGS AND OR HEAT ADVISORIES.
UNFORTUNATELY, WE DON'T REALLY SEE ANY CHANCE OF RAIN ABOVE ABOUT
30% OVER THE NEXT WEEK OR SO, HIGHEST OVER THE WEEKEND AND MAINLY
NEAR THE TENNESSEE RIVER AND NORTHEAST MISSISSIPPI.

AVIATION
(06Z TAFS)
ISSUED AT 1113 PM CDT WED JUL 23 2025
NO MAJOR AVIATION CONCERNS THIS PERIOD. A FEW PATCHES OF FOG MAY
DEVELOP NEAR MKL AND TUP OVERNIGHT, BUT OVERALL REDUCTION IN VSBYS

ANS
FIRE WEATHER
ISSUED AT 1113 PM CDT WED JUL 23 2025
A STRONG RIDGE AND SURFACE HIGH PRESSURE WILL KEEP FIRE WEATHER
CONCERNS MINIMAL FOR THE FORESEEABLE FUTURE. MINRH VALUES WILL
BE AROUND IN THE MID 50'S TO AROUND 60% EACH DAY. CONVECTION WILL
PROVIDE VERY SPORADIC RELIEF FROM THE HEAT AND HUMIDITY IN THE
FORM OF ISOLATED SHOWERS AND THUNDERSTORMS.
