AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 639 PM EDT TUE SEP 1 2015 ...UPDATED AVIATION DISCUSSION... ...FORECAST UPDATE... ISSUED AT 535 PM EDT TUE SEP 1 2015 QUICK UPDATE TO ACCOUNT FOR THE SHOWERS THAT HAVE DEVELOPED OVER BOWLING GREEN, PLUS THE SMALL CHANCE OF AN ISOLATED SHOWER EASTWARD THROUGH THE GLASGOW AREA AND UP TO AROUND CAMPBELLSVILLE OVER THE NEXT COUPLE OF HOURS. RADAR SHOWING SOME SMALL AREAS OF INCREASED REFLECTIVITIES ALOFT IN THAT REGION. .SHORT TERM (NOW THROUGH WEDNESDAY NIGHT)... ISSUED AT 312 PM EDT TUE SEP 1 2015 OVERALL PATTERN FEATURES AN UPPER RIDGE CENTERED OVER THE SE CONUS, MEANWHILE A WEAK UPPER LOW IS SPINNING OVER CENTRAL INDIANA. THIS FEATURE WILL GRADUALLY ROUND THE APEX OF THE RIDGE, SLIDING JUST NORTHEAST AND THEN EAST OF THE CWA THROUGH THE SHORT TERM. VERY ISOLATED SHOWERS AND STORMS HAVE DEVELOPED OVER SOUTHERN INDIANA THIS AFTERNOON. MOST SPOTS WILL STAY DRY, HOWEVER VERY LOCALIZED SPOTS COULD SEE BRIEF HEAVY RAINFALL, CLOUD TO GROUND LIGHTNING AND GUSTY WINDS UP TO 40 MPH. UPPER FEATURE WILL GRADUALLY SLIDE EAST OVERNGHT AND THEN SOUTHEAST TOWARD DAWN. WILL GO DRY THROUGH THE OVERNIGHT WITH THE LOSS OF DAYTIME HEATING/INSTABILITY HOWEVER WILL BEGIN TO REINTRODUCE SLIGHT CHANCE POPS ACROSS OUR FAR NE DURING THE AFTERNOON HOURS ON WEDNESDAY, LINGERING INTO WEDNESDAY NIGHT AS THE UPPER LOW BEGINS TO PUSH EAST OF THE AREA. FOR TONIGHT, AM A BIT CONCERNED ABOUT THE POTENTIAL FOR SOME PATCHY DENSE FOG, ESPECIALLY IN THE RIVER VALLEYS. OVERALL CONDITIONS WILL BE FAVORABLE FOR RADIATIONAL COOLING. THINK THE MOST LIKELY AREAS WILL BE WEST OF I-65 AND ACROSS SOUTHERN KY. OUR NE SHOULD SEE A BIT MORE CLOUD COVER INFLUENCE FROM NEAR THE UPPER LOW SO MORE OPTIMISIC THAT DENSE FOG WILL NOT FORM THERE. WILL MENTION IN THE ZONES AND IN THE HWO, BUT WILL HOLD OFF ANY ANY ADDITIONAL HEADLINES AT THIS TIME. MOST LOWS WILL BE IN THE MID AND UPPER 60S TONIGHT WITH A FEW LOCATIONS STAYING AROUND 70. WEDNESDAY HIGHS SHOULD BE A DEGREE OR TWO WARMER THAN TODAY, SO WILL GO WITH AND 88 TO 93 RANGE. AREAS WEST HAVE THE BEST SHOT AT THE 92S AND 93S. WEDNESDAY NIGHT LOWS WILL BE SLIGHTLY MILDER IN THE 68 TO 73 RANGE. .LONG TERM (THURSDAY THROUGH TUESDAY)... ISSUED AT 305 PM EDT TUE SEP 1 2015 ONLY SUBTLE CHANGES IN THE LONG TERM WITH MOSTLY A PERSISTENT FORECAST DAY TO DAY. RIDGING ALOFT IS THE REASON FOR THIS PERSISTENCE...HOWEVER LATEST GFS/EURO NOW HINTING AT A WEAK INVERTED TROUGH MEANDERING ACROSS THE REGION AT VARIOUS TIMES. THIS BOUNDARY MAY BE ENOUGH TO FOCUS ISOLATED DIURNAL CONVECTION. COVERAGE WILL BE LIMITED BY PRECIPITABLE WATERS ONLY IN THE 1.3-1.5 INCH RANGE. SUPERBLEND CAME UP WITH A COUPLE OF PERIODS IN THE SCATTERED RANGE...BUT IN KEEPING WITH A PERSISTENCE FORECAST AND THAT DRY AIR IN PLACE DECIDED TO LIMIT TO ISOLATED COVERAGE. OTHERWISE OUR TEMPERATURE FORECAST REMAINS A LITTLE ABOVE NORMAL EACH DAY. BACKED OFF FOR DAY 7 CLOSER TO NORMAL...AS THICKNESSES ARE FORECAST TO COME DOWN SOME. && .AVIATION (00Z TAF UPDATE)... ISSUED AT 639 PM EDT TUE SEP 1 2015 WITH LITTLE CHANGE IN THE OVERALL METEOROLOGICAL SET-UP, WILL GO WITH A LARGELY PERSISTENCE FORECAST FOR THIS TAF PACKAGE. SO...WILL HAVE TO CONTEND WITH THE POSSIBILITY OF MORNING FOG ONCE AGAIN, ESPECIALLY AT BWG. LEX AND EVEN SDF MAY BRIEFLY DROP BELOW 7SM AROUND DAWN (BR AT LEX, URBAN HZ AT SDF). OUTSIDE OF THAT, THIS TAF PERIOD SHOULD BE LARGELY FREE OF PROBLEMS FOR AVIATORS. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
