SHORT TERM
 
(THIS EVENING THROUGH SATURDAY)  
ISSUED AT 300 PM EDT FRI SEP 24 2021  
 
VERY PLEASANT WEATHER THIS AFTERNOON. HIGH PRESSURE JUST OFF TO OUR  
SOUTH CONTINUES TO SLOWLY SHIFT EAST, WITH SUNNY SKIES AND LIGHT  
WINDS OUT OF THE SOUTHWEST. TEMPERATURES ARE MAXING OUT IN THE LOW  
TO MID 70S.  
 
AN UPPER LEVEL TROUGH AND WEAK COLD FRONT APPROACH FROM THE  
NORTHWEST OVERNIGHT. SCATTERED CIRRUS WILL SPREAD IN FROM THE WEST  
THIS EVENING AND THICKEN OVERNIGHT. LOWER CLOUDS ALONG THE FRONTAL  
ZONE AND A BAND OF LIGHT SHOWERS WILL MOVE THROUGH THE AREA SATURDAY  
MORNING, WITH THE BULK OF THE LIGHT RAIN CONFINED TO AREAS NEAR AND  
NORTH OF THE WESTERN KENTUCKY AND BLUEGRASS PARKWAYS. RAINFALL TOTALS  
WILL BE AROUND A TENTH OF AN INCH OR LESS IN SOUTHERN IN AND THE  
NORTHERN HALF OF CENTRAL KY. ANY RAIN SHOULD BE QUITE BRIEF (2-3  
HOURS) AT ANY ONE LOCATION, WITH CONDITIONS DRYING OUT INTO THE  
AFTERNOON HOURS.  
 
WITH MORE CLOUDS IN THE MORNING, TEMPERATURES WILL CREEP THROUGH THE  
50S AND 60S IN THE MORNING, EVENTUALLY TOPPING OUT IN THE UPPER 60S  
TO LOWER 70S UNDER LATE DAY SUNSHINE.  
   
LONG TERM
 
(SATURDAY NIGHT THROUGH FRIDAY)  
ISSUED AT 307 PM EDT FRI SEP 24 2021  
 
THE LONG-TERM, STARTING SUNDAY, IS GOING TO BE A VERY NICE WEATHER  
PERIOD. HIGH TEMPERATURES ON SUNDAY, BEHIND THE COLD FRONT, WILL  
REACH INTO THE 70S, BUT AS HIGH PRESSURE SETS UP TO OUR SOUTHEAST IN  
THE FOLLOWING DAYS, RETURN FLOW WILL LIFT TEMPERATURES INTO THE  
UPPER 70S (EASTERN PARTS OF CWA) TO MID 80S THROUGH THE MIDDLE OF  
NEXT WEEK. THIS PLACES TEMPERATURES NEAR NORMAL TO SLIGHTLY WARMER  
THAN NORMAL FOR THIS TIME OF YEAR WITH LOTS OF SUNSHINE. DEW POINTS  
WILL ALSO RECOVER SLIGHTLY TO THE LOW 60S, STILL NOT TOO BAD.
