NEAR TERM
(TONIGHT)
ISSUED AT 153 PM CDT WED JUN 24 2026
HIGH PRESSURE OVER THE OH VALLEY AND APPALACHIANS CONTINUES TO BE
THE DOMINANT INFLUENCE ON WEATHER LOCALLY, KEEPING RELATIVELY DRY
AND SLIGHTLY COOLER TEMPS IN PLACE. CURRENT TEMPS RANGE FROM THE
UPPER 70S TO LOWER 80S AND WILL TOP OUT NEAR 85 DEGREES IN SEVERAL
LOCATIONS BEFORE THE AFTERNOON IS THROUGH. WITH MOSTLY CLEAR TO
PARTLY CLOUDY SKIES FORECAST OVERNIGHT COMBINED WITH CALM WINDS,
FOG WILL BE THE MAIN CONCERN. CONDITIONS WILL BE MONITORED IN CASE
A DENSE FOG ADVISORY IS NEEDED INTO THE MORNING HOURS. OTHERWISE,
LOWS WILL RANGE FROM THE LOW TO MID 60S OVERNIGHT.
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.
