-- Changed Discussion --
(THIS EVENING THROUGH SATURDAY NIGHT) ISSUED AT 348 PM EDT FRI APR 17 2015 CLOUDS CONTINUE TO SLOWLY BREAK UP THIS AFTERNOON AS HIGH PRESSURE BUILDS INTO THE OH VALLEY REGION. THIS DRYING SHOULD ALLOW MOST OF THE REMAINING CLOUDS TO DISSIPATE TONIGHT...WITH THE EXCEPTION OF THE SOUTHERN COUNTIES WHERE SOME MID LEVEL CLOUDS COULD MOVE IN DUE A SHORTWAVE MOVING ACROSS THE TN REGION. THAT BEING SAID...SEEMS LIKE A GOOD SET UP FOR VALLEY FOG TONIGHT...ESPECIALLY IN AREAS WHERE THERE ARE CLEARER SKIES AND GOOD RADIATIONAL COOLING. SO WILL MENTION THIS IN THE HWO. BY SATURDAY...A CLOSED UPPER LOW EJECTS INTO THE CENTRAL PLAINS...AND A SHORTWAVE MOVES OUT OF THE BASE OF THE LOW...CROSSING THE LOWER MS RIVER VALLEY AND NORTHEAST INTO THE OH AND TN VALLEYS. SURFACE LOW PRESSURE AND A DEVELOPING WARM FRONT WILL BRING A SURGE OF MOIST AIR INTO EAST KENTUCKY WITH SLIGHT CHANCE POPS MAKING IT INTO POINTS SOUTH OF THE HAL ROGERS PARKWAY BY SATURDAY AFTERNOON. HOWEVER...PRECIP WILL HOLD OFF LONG ENOUGH FOR YOU TO ENJOY A WARM AND SUNNY DAY WITH TEMPERATURES REACHING THE 80 DEGREE MARK IN MOST LOCATIONS. THE BEST CHANCE FOR MEASUREABLE PRECIP WILL BE AFTER 06Z SUNDAY. .LONG TERM...(SATURDAY NIGHT THROUGH THURSDAY) ISSUED AT 348 PM EDT FRI APR 17 2015 THE LONG TERM DISCUSSION WILL BE ISSUED SHORTLY.
