UPDATE
 
 
ISSUED AT 915 PM EDT WED MAY 29 2024  
 
00Z SFC ANALYSIS SHOW HIGH PRESSURE NOSING INTO THE AREA FROM THE  
WEST BUT NOT BEFORE ONE LAST SHOT AT A COUPLE OF SHOWERS DROP  
SOUTH THROUGH EASTERN KENTUCKY THIS EVENING. THESE SHOWERS WILL BE  
DRYING OUT AND GONE WITHIN AN HOUR OR TWO WITH MOST PLACES  
REMAINING DRY. THERE IS ANOTHER BAND OF CLOUDS ACCOMPANYING THE  
SHOWERS BUT THESE SHOULD MOSTLY CLEAR OUT INTO THE EARLY MORNING  
HOURS. AS A RESULT, A SMALL RIDGE TO VALLEY TEMPERATURE SPLIT CAN  
BE EXPECTED ALONG WITH A BIT OF VALLEY FOG. CURRENTLY,  
TEMPERATURES ARE RUNNING IN THE LOW TO MID 60S MOST PLACES, BUT IN  
THE UPPER 50S FOR A FEW OF THE SHELTERED SPOTS. MEANWHILE, AMID  
LIGHT WINDS FROM THE NORTH TO NORTHWEST, DEWPOINTS HAVE DRIED  
INTO THE LOWER 50S. DID ADJUST THE POPS AND SKY COVER THROUGH THE  
REST OF THE EVENING AS WELL AS INCLUDING THE CURRENT OBS AND  
TRENDS FOR THE T/TD/SKY GRIDS. THESE ADJUSTMENTS HAVE BEEN SENT TO  
THE NDFD AND WEB SERVERS ALONG WITH A FRESHENING OF THE ZONES,  
HWO, AND SAFS.  
 

 
   
SHORT TERM
 
(THIS EVENING THROUGH THURSDAY NIGHT)  
ISSUED AT 330 PM EDT WED MAY 29 2024  
 
A SURFACE LOW IS SITTING OVER WESTERN PA FORCING A COLD FRONT  
ACROSS THE FORECAST AREA THIS AFTERNOON. POST-FRONTAL SHOWERS AND  
THUNDERSTORMS ARE MOVING SOUTHWARD ACROSS OHIO AND WEST VIRGINIA  
CURRENTLY AS FLOW BECOMES MORE WNW-NNW BEHIND THIS FRONT.  
EXPECTING THESE WILL MAKE THEIR WAY INTO EASTERN KY IN THE NEXT  
FEW HOURS. ANY THUNDERSTORMS THAT DO FORM SHOULD REMAIN SUB-  
SEVERE, AS PARAMETERS ARE NOT WORTHWHILE WITH LACK OF FAVORABLE  
INSTABILITY TODAY. MOST OF THE ACTIVITY WILL LIKELY BE WINDING  
DOWN THIS EVENING WHEN DIURNAL HEATING IS GONE.  
 
PATCHY FOG IS LIKELY AGAIN TONIGHT WITH CONDITIONS GOING CALM AND  
COOLER TEMPERATURES EXPECTED. THIS IS MOSTLY FOR THE TYPICAL  
VALLEY LOCATIONS WITH POOR DRAINAGE WINDS AND ANY AREAS THAT  
RECEIVE RAINFALL THIS AFTERNOON.  
 
OUTSIDE OF MORNING FOG IT LOOKS TO BE MOSTLY DRY FOR THURSDAY  
UNDER A BROAD AREA OF HIGH PRESSURE. BELOW NORMAL TEMPERATURES  
WILL CONTINUE WITH HIGHS IN THE LOW TO MID 70S.  
   
LONG TERM
 
(FRIDAY THROUGH WEDNESDAY)  
ISSUED AT 330 PM EDT WED MAY 29 2024  
 
ANOTHER DRY DAY WITH BELOW NORMAL TEMPERATURES IS EXPECTED FRIDAY  
UNDER CONTINUED HIGH PRESSURE. IT WILL BE RATHER COMFORTABLE,  
THOUGH ON THE DRY SIDE WITH AFTERNOON RH VALUES IN THE 20S AND  
30S ACROSS THE AREA.  
 
THE CHANGE UP COMES LATE SATURDAY AS SHOWERS AND THUNDERSTORMS  
RETURN AND TEMPERATURES REACH THE 80S FOR SOME LOCATIONS. THE  
SYSTEM RESPONSIBLE FOR THE RETURN OF PRECIPITATION WILL BE A LOW  
PRESSURE SYSTEM THAT WILL MOVE EASTWARD OUT OF MO AND OVER IN/IL.  
THE ASSOCIATED TROUGH LOOKS TO EXTEND OVER THE AREA FOR MUCH OF  
THE WEEKEND AND POSSIBLY INTO MONDAY, SUBSEQUENTLY KEEPING SHOWERS  
AND THUNDERSTORMS IN THE FORECAST THROUGH THAT TIME FRAME.  
 
LOOKING OUT A STRONG HIGH PRESSURE SYSTEM OVER BERMUDA WILL DRIFT  
WESTWARD JUST OFF THE COAST OF THE CAROLINAS. TEMPERATURES LOOK  
TO HEAT UP STARTING MONDAY INTO MID-WEEK WHERE SOME LOCATIONS  
COULD BE WELL INTO THE 80S WEDNESDAY AFTERNOON. THERE REMAINS A  
CHANCE FOR DIURNAL SHOWERS AND THUNDERSTORMS EACH AFTERNOON NEXT  
WEEK WITH DAYTIME HEATING.  
 

 
   
AVIATION
 
(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)  
ISSUED AT 820 PM EDT WED MAY 29 2024  
 
MAINLY VFR CONDITIONS WILL BE THE RULE THROUGH THE AVIATION  
PERIOD. PATCHY, TO AREAS OF, FOG WILL LIKELY DEVELOP OVERNIGHT IN  
THE TYPICAL VALLEY SPOTS. EXPECT MOST OF THE STRATUS OR FOG THAT  
COULD IMPACT THE TERMINALS TO BE FLEETING OR AT WORST AFFECTING A  
SITE OR TWO FOR JUST AN HOUR OR TWO BEFORE DAWN. HAVE LEFT THAT  
POTENTIAL OUT OF THE TAF FORECAST FOR NOW, BUT IT WILL BE  
MONITORED THROUGH THE NIGHT. WINDS WILL BE LIGHT AND VARIABLE  
THROUGH THE PERIOD.
