NATIONAL WEATHER SERVICE LOUISVILLE KY
620 AM EDT SUN JUN 29 2025
KEY MESSAGES

* ISOLATED SHOWERS AND STORMS ARE POSSIBLE FOR INDEPENDENCE DAY, BUT
MOST OF THE DAY WILL BE DRY.
SHORT TERM /THROUGH MONDAY/
ISSUED AT 400 AM EDT SUN JUN 29 2025
EXPECT TO BEGIN THE DAY WITH AT LEAST PATCHY FOG, MAINLY IN AREAS
THAT HAD THE HEAVIEST RAIN ON SATURDAY. LOCALIZED DENSE FOG IS
POSSIBLE IN SUCH LOCATIONS, BUT NO SIGNIFICANT RESTRICTIONS TO VIS
HAVE BEEN NOTED YET. WILL CONTINUE TO MONITOR, AND LIKELY HANDLE FOG
AREAS WITH SPECIAL WEATHER STATEMENTS, AS COVERAGE WILL LIKELY NOT
BE SUFFICIENT TO JUSTIFY AN ADVISORY.
ANY FOG SHOULD BURN OFF FAIRLY QUICKLY AFTER SUNRISE, LEAVING PLENTY
OF OPPORTUNITY TO REACH CONVECTIVE TEMPS THIS AFTERNOON. MAX TEMP
FORECAST IS VERY CLOSE TO PERSISTENCE, EVEN IF IT TAKES A BIT LONGER
TO GET THERE. LOOK FOR SCATTERED STORMS TO DEVELOP, PERHAPS WITH A
BIT LESS COVERAGE THAN SATURDAY. NOT EXPECTING ANY ORGANIZED STORMS
GIVEN THE LACK OF SHEAR, BUT THIS ENVIRONMENT IS JUICY ENOUGH FOR
FREQUENT LIGHTNING, LOCALLY HEAVY RAINFALL, AND PERHAPS A PULSE WIND
THREAT.
THUNDERSTORMS SHOULD DISSIPATE QUICKLY AROUND SUNSET AS INSTABILITY
IS LOST. FOR MONDAY WE'LL HAVE AN UPPER SHORTWAVE TROF MOVING
THROUGH THE UPPER MIDWEST, AND STARTING TO PUSH A COLD FRONT
SOUTHEAST TOWARD THE OHIO VALLEY. FORECAST SOUNDINGS SUGGEST
MODERATE INSTABILITY, AND WHILE SHEAR INCREASES SLIGHTLY IT REMAINS
FAIRLY WEAK. SPC HAS PLACED A MARGINAL RISK ACROSS MUCH OF THE AREA
FOR DAY 2, WHICH ON THE SURFACE MAY BE A BIT GENEROUS. THAT SAID,
EVEN IF CONVECTION REMAINS DISORGANIZED THE INSTABILITY ALONE
SUPPORTS AT LEAST A PULSE WIND THREAT.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
ISSUED AT 400 AM EDT SUN JUN 29 2025
TUESDAY - THURSDAY...
A COLD FRONT WILL PUSH THROUGH THE REGION TUESDAY, ALLOWING DEW
POINTS TO DROP AND CONDITIONS TO BECOME MORE COMFORTABLE WED-THU.
TEMPERATURES WILL REMAIN NEAR NORMAL IN THE MID-UPPER 80S. SFC HIGH
PRESSURE OVER THE REGION, WILL KEEP CONDITIONS DRY AND SKIES MOSTLY
SUNNY.
INDEPENDENCE DAY - NEXT WEEKEND...
UPPER TROF LIFTS OUT OF THE NORTHEAST CONUS AND EASTERN CANADA,
ALLOWING FOR BRIEF RIDGING ALOFT BEFORE TRANSITIONING TO A MORE
ZONAL FLOW AGAIN. TEMPS WILL TREND BACK ABOVE NORMAL, AND HUMIDITY
WILL SLOWLY INCREASE. SLIGHT CHANCE FOR SHOWERS OR STORMS ON
INDEPENDENCE DAY, BUT MOST OF THE DAY WILL REMAIN DRY. PRECIP
CHANCES WILL SLOWLY RAMP UP NEXT WEEKEND.
AVIATION /12Z TAFS THROUGH 18Z MONDAY/
ISSUED AT 608 AM EDT SUN JUN 29 2025
FOG IS NOT REALLY IMPACTING ANY OF THE TERMINALS AT THIS TIME,
THOUGH BWG IS HINTING THAT VIS MAY DROP. THE WINDOW FOR RESTRICTIONS
TO VIS IS RAPIDLY CLOSING, SO WILL INITIALIZE VFR. HNB HAS HAD JUST
ENOUGH BREEZE TO LIFT THE MOISTURE INTO AN IFR STRATUS CIG. THAT
SHOULD SCATTER OUT AROUND 13Z.
OTHERWISE THE TAFS ARE LARGELY A PERSISTENCE FORECAST FROM THE LAST
COUPLE OF DAYS, AS SCATTERED AFTERNOON STORMS ARE EXPECTED AGAIN.
WILL COVER IT WITH A PROB30 AND INCLUDE IFR VIS WITH THE HEAVIEST
RAIN. MAIN UNCERTAINTY IS WHETHER STORMS WILL DIRECTLY IMPACT EACH
OF THE TERMINALS. AFTER SUNSET THE INSTABILITY IS LOST, WHICH WILL
LEAVE US HIGH AND DRY FOR THE NIGHT.
