NEAR TERM
(REST OF TODAY AND TONIGHT)
ISSUED AT 929 AM CDT WED JUN 24 2026
DENSE FOG HAS DISSIPATED IN OUR EASTERN VALLEYS THIS MORNING, THUS
THE DENSE FOG ADVISORY WAS BEEN ALLOWED TO EXPIRE. AN MCV WAS
EVIDENT IN SATELLITE IMAGERY MOVING SOUTHEAST THROUGH CENTRAL MS.
THIS WILL IGNITE NEW THUNDERSTORMS TODAY WELL TO OUR SOUTH AND
SOUTHWEST. SOME HIGH CLOUDINESS FROM ANVIL BLOWOFF MAY SPILL INTO
OUR COUNTIES, BUT OVERALL A MOSTLY SUNNY DAY IS ANTICIPATED WITH
HIGHS IN THE LOWER TO MIDDLE 80S. MORE PATCHY DENSE FOG IS
EXPECTED AGAIN TONIGHT WITH LOWS IN THE LOWER TO MIDDLE 60S.
SHORT TERM
(THURSDAY THROUGH FRIDAY)
ISSUED AT 929 AM CDT WED JUN 24 2026
YET ANOTHER MCV WILL SPILL SOUTHEAST INTO THE MID SOUTH ON
THURSDAY MORNING, WITH A FEW SHOWERS ENTERING NORTHWEST ALABAMA.
LOW CHANCES OF NEW SHOWERS AND A FEW THUNDERSTORMS RELATED TO THIS
MCV MAY REACH FURTHER NORTHEAST DURING THE AFTERNOON. NO SEVERE
WEATHER IS EXPECTED HOWEVER. THE MCV AXIS BY MID EVENING WILL BE
ALONG THE I-65 CORRIDOR, BUT LOSS OF DAYTIME HEATING MAY PRECLUDE
PRECIPITATION MUCH EAST OF THIS CORRIDOR. AFTER HIGHS IN THE
MIDDLE TO UPPER 80S, OVERNIGHT LOWS WILL ONLY DIP INTO THE UPPER
60S TO LOWER 70S.
LONG TERM
(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 936 PM CDT TUE JUN 23 2026
A FAIRLY STOUT UPPER-LEVEL RIDGE OF HIGH PRESSURE OVER TEXAS WILL
BUILD INTO THE REGION THIS WEEKEND INTO EARLY NEXT WEEK. A VERY WARM,
HUMID AIR MASS WILL SPREAD EASTWARD OVER THE TENNESSEE VALLEY
UNDERNEATH THIS RIDGE AND THE END RESULT WILL LIKELY BE MAJOR TO
POTENTIALLY EXTREME HEAT IMPACTS DURING THIS TIMEFRAME. AMPLE
SUNSHINE EACH DAY WILL PUSH HIGH TEMPERATURES INTO THE LOW TO MID 90S
SATURDAY AND SUNDAY AND THE MID TO POTENTIALLY UPPER 90S MONDAY AND
TUESDAY. THESE HOT TEMPERATURES, COMBINED WITH DEWPOINTS IN THE LOW
TO MID 70S WILL CREATE HEAT INDEX VALUES OVER 100 DEGREES EACH DAY,
AND POTENTIALLY ABOVE 105 DEGREES SUNDAY, MONDAY, AND TUESDAY. SHOULD
THESE TRENDS CONTINUE, HEAT ADVISORY PRODUCTS MAY BE NEEDED EARLY
NEXT WEEK -- ESPECIALLY FACTORING THE VERY LIMITED RECOVERIES
OVERNIGHT (LOWS IN THE MID 70S). NWS HEAT RISK VALUES HIGHLIGHT A
VAST MAJORITY OF THE REGION IN MAJOR RISK FOR THIS TIMEFRAME,
MEANING THAT THIS HEAT WILL LIKELY AFFECT ANYONE SENSITIVE TO HEAT
(ESPECIALLY THOSE WITHOUT ADEQUATE COOLING/HYDRATION) AS WELL AS SOME
HEALTH SYSTEMS AND INDUSTRIES. IF YOU HAVE OUTDOOR PLANS THIS
WEEKEND INTO EARLY NEXT WEEK, BE SURE TO PRACTICE HEAT SAFETY SUCH AS
STAYING HYDRATED AND SEEKING SHADE WHEN OUTDOORS TO AVOID HEAT
RELATED ILLNESS.
