KEY MESSAGES
* HEAT ADVISORY REMAINS THROUGH WEDNESDAY DUE TO MULTIPLE DAYS OF
HEAT INDICES NEAR 100 TO 105 AND HEAT INDICES ONLY FALLING INTO
THE MID TO UPPER 70S AT NIGHT.
SHORT TERM /THROUGH THURSDAY/
ISSUED AT 352 PM EDT TUE JUN 24 2025
CURRENTLY, AN UPPER LEVEL HIGH SITS CENTERED OVER THE APPALACHIAN
MOUNTAINS NEAR THE WEST VIRGINIA VIRGINIA BORDER. SURFACE HIGH
PRESSURE OVER THE SOUTHEAST CONTINUES TO FUNNEL MOISTURE UP THE
MISSISSIPPI AND OHIO VALLEYS, RESULTING IN HIGH LOW LEVEL MOISTURE
OVER SOUTHERN INDIANA AND CENTRAL KENTUCKY. DEW POINTS REMAIN MOSTLY
IN THE LOW TO MID 70S. DIURNAL WARMING HAS PUSHED TEMPERATURES INTO
THE LOW TO MID 90S. THE KENTUCKY MESONET SHOWS HEAT INDICES ACROSS
CENTRAL KENTUCKY RANGING FROM 98 TO 105. SATELLITE IMAGERY SHOWS
CUMULUS CLOUDS MOVING IN AN ANTICYCLONIC PATTERN AROUND THE LOW.
ADDITIONAL CLOUD DEVELOPMENT CAN BE SEEN FROM DIFFERENTIAL HEATING
ACROSS AN AREA FROM WARREN COUNTY TO CHRISTIAN COUNTY TO THE WEST.
YOU CAN ALSO SEE ENHANCEMENT OVER LEXINGTON FROM THE URBAN HEAT
ISLAND. IN THE COMING HOURS SOME ISOLATED SHOWER AND THUNDERSTORM
ACTIVITY WILL LIKELY DEVELOP.
TONIGHT, ANY REMAINING SHOWERS/THUNDERSTORMS WILL COME TO AN END
WITH THE LOSS OF DIURNAL WARMING, AND EVEN WITH LIGHT WINDS AND
CLEARING SKIES, TEMPERATURES ARE ONLY EXPECTED TO FALL INTO THE 70S.
THIS WILL ALSO LEAD TO PATCHY FOG ACROSS THE AREA. THE BEST CHANCES
WILL BE TOWARDS EASTERN KENTUCKY.
TOMORROW, EXPECT MORE OF THE SAME AS STRONG SUNSHINE LIFTS
TEMPERATURES BACK INTO THE LOW TO MID 90S. WITH DEW POINTS IN THE
MID TO UPPER 70S, HEAT INDICES WILL CLIMB BACK INTO THE UPPER 90S TO
AROUND 105. BELIEVE SHOWERS AND THUNDERSTORMS WILL BE MORE LIKELY AS
A WAVE MOVES WEST BEFORE NORTHWEST AWAY FROM THE CWA. CHANCES WILL
BE BETTER ALONG AND NORTH OF INTERSTATE 64, BUT ISOLATED TO
SCATTERED CHANCES WILL ALSO BE POSSIBLE FARTHER SOUTH THROUGHOUT
CENTRAL KENTUCKY.
LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/
ISSUED AT 352 PM EDT TUE JUN 24 2025
FROM THURSDAY TO MONDAY, EXPECT LITTLE DAY TO DAY CHANGE.
TEMPERATURES ARE EXPECTED TO TREND SLIGHTLY COOLER BY THIS WEEKEND,
FALLING FROM THE LOW TO MID 90S ON THURSDAY AND FRIDAY TO THE UPPER
80S TO LOW 90S BY THE WEEKEND. THE COOLER OF THESE TEMPERATURES ARE
EXPECTED OVER THE BLUEGRASS. SURFACE HIGH PRESSURE OVER THE
SOUTHEAST WILL CONTINUE TO SENT MOISTURE UP THE MISSISSIPPI AND OHIO
VALLEYS AS THE UPPER RIDGE BECOMES MORE ZONAL, OVER THE GREAT LAKES.
MOSTLY SUNNY DAYS WITH AFTERNOON/EVENING CUMULUS THAT PRODUCE
ISOLATED TO SCATTERED RAIN CHANCES.
TUESDAY, MODEL AGREEMENT CONTINUES TO LOOK FAIRLY GOOD AS THE
GLOBAL MODELS BEGIN TO FORM A RIDGE OVER THE ROCKIES AND A TROUGH
OVER THE EAST COAST. NORTHWEST FLOW OVER THE LOWER OHIO VALLEY WOULD
PUSH A COLD FRONT TOWARDS THE CWA, BRINGING DRIER AIR AND COOLER
TEMPERATURES. HIGHS ON TUESDAY FALL INTO THE MID TO UPPER 80S.
THE HEAT ADVISORY IS IN PLACE UNTIL WEDNESDAY EVENING, BUT PART OR
ALL OF IT MAY NEED TO BE EXTENDED IN THE FUTURE, BUT WITH INCREASING
RAIN CHANCES TO THE NORTH AND EAST OVER THE NEXT COUPLE OF DAYS,
THIS COULD LIMIT THE EXTENT OF WHAT IS NEEDED.
AVIATION /06Z TAFS THROUGH 12Z THURSDAY/
ISSUED AT 143 AM EDT WED JUN 25 2025
SHOWERS AND STORMS HAVE DISSIPATED AND SKIES CONTINUE TO CLEAR.
WINDS WILL BE LIGHT TO CALM AND THAT MAY DEVELOP PATCHY FOG ACROSS
THE AREA. THERE MAY BE SOME MINOR VIS ISSUES BUT GIVEN HOW WARM WE
ARE NOT SURE WE WILL SEE FOG DEVELOPMENT. ANOTHER DAY WHERE WE COULD
SEE SCATTERED CU DEVELOP WITH ISOLATED SHOWERS/STORMS IN THE
AFTERNOON. WINDS REMAIN GENERALLY LIGHT OUT OF THE SW AND WE WILL
CONTINUE THE CYCLE AGAIN TOMORROW NIGHT INTO THURSDAY.
