NWS Louisville, KY wrote its last area forecast discussion before the first event at Sep 26, 1:00 AM CST, 2 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 300 AM EDT SAT SEP 26 2009 .SHORT TERM (TODAY AND TONIGHT)... ALL SHORT RANGE AND ENSEMBLE MODELS ARE IN GOOD AGREEMENT THIS MORNING FOR THE NEXT 36 HOURS. THE MUCH ADVERTISED CLOSED UPPER LOW WILL CONTINUE TO GRADUALLY SHIFT TO THE EAST. ON THE EAST SIDE OF THE LOW THIS MORNING A SHORT WAVE WILL TRACK NORTHEAST WHICH WILL INCREASE PRECIPITATION ACROSS CENTRAL TENNESSEE AND EAST KENTUCKY. HAVE UPPED THE POPS ACROSS THE EASTERN PORTION OF THE FORECAST AREA THROUGH 18Z INTO THE CATEGORICAL RANGE... BASICALLY WHERE THE FLASH FLOOD WATCH IS IN PLACE. DRIER AIR WILL WORK INTO THE REGION THIS AFTERNOON WHICH SHOULD HELP DIMINISH THE RAIN FROM WEST TO EAST BUT MAY HELP DESTABILIZE THE ATMOSPHERE AS THE UPPER LOW MOVES OVER THE AREA. SO AFTER A PERIOD OF DIMINISHING RAIN ANOTHER ROUND OF SHOWERS AND ISOLATED THUNDERSTORMS WILL BE POSSIBLE LATE IN THE DAY AND EVENING. THE RAIN WILL END OVERNIGHT AS A DRIER WESTERLY FLOW DEVELOPS. WITH THE EXPECTED CLOUDS AND PRECIPITATION HIGHS THIS AFTERNOON WILL HOLD IN THE 70S WITH LOWS TONIGHT FALLING INTO THE MID AND UPPER 50S. AS MENTIONED THE PLACEMENT OF THE FLASH FLOOD WATCH IS IN GOOD SHAPE AND NO CHANGES ARE PLANNED. ALSO PATCHY DENSE FOG WILL BE AN ISSUE THIS MORNING ESPECIALLY ACROSS THE WESTERN PORTION OF THE FORECAST AREA AND WILL HANDLE THIS WITH SPECIAL WEATHER STATEMENTS. .LONG TERM (SUNDAY THROUGH FRIDAY)... SUNDAY THROUGH TUESDAY... UPPER AIR PATTERN SHOWS TWO SYSTEMS TO AFFECT THE REGION FOR THE EARLY PART OF NEXT WEEK. THE EASTERNMOST SYSTEM WILL BE MOVING UP THE ST LAWRENCE VALLEY SUNDAY...WITH ITS RELATED 500MB TROUGH AXIS MOVING EAST OF KENTUCKY DURING THE MORNING HOURS. THE SECOND SYSTEM WILL STILL BE IN ALBERTA CANADA SUNDAY...BUT WILL QUICKLY SCOOT SOUTHEAST TOWARDS THE GREAT LAKES BY MONDAY. ONCE THE TROUGH AXIS MOVES EAST SUNDAY...SUBSIDENCE AND DRIER AIR WILL LEAD TO CLEARING SKIES CERTAINLY BY AFTERNOON AND PROBABLY BY MORNING ACROSS OUR WESTERN COUNTIES. WITH MILD PACIFIC AIR AND LIGHT SOUTHWEST WINDS EXPECTED SUNDAY...TEMPERATURES SHOULD RECOVER INTO THE MID TO UPPER 70S FOR AFTERNOON HIGHS. A POWERFUL JET WILL DIVE SOUTHEAST ACROSS THE UPPER MIDWEST LATE SUNDAY AND WILL HELP DEVELOP A STRONG AUTUMNAL CYCLONE ACROSS THE GREAT LAKES BY MONDAY MORNING. BOTH THE 00Z NAM AND GFS ARE SIMILAR IN RAPIDLY DEEPENING LOW PRESSURE TO AROUND 980MB ACROSS NORTHERN MICHIGAN. THIS WILL BRING THE COOLEST AIR OF THIS YOUNG FALL SEASON INTO THE LOWER OHIO VALLEY BEGINNING MONDAY. EXPECT VERY MILD TEMPERATURES EARLY MONDAY AS A STRENGTHENING SOUTHWESTERLY LOW LEVEL JET AHEAD OF A SHARP COLD FRONT WILL PREVENT MUCH DECOUPLING OF THE BOUNDARY LAYER OVERNIGHT. THE FRONT ITSELF WILL MOVE SOUTHEAST OF THE OHIO RIVER AROUND DAWN. WITH A STRONG PRESSURE GRADIENT DEVELOPING AND COLD AIR ADVECTION MONDAY...EXPECT BREEZY WINDS DURING THE AFTERNOON WITH SOME GUSTS AROUND 30 MPH. WITH SCANT MOISTURE AHEAD OF THIS BOUNDARY...ONLY A FEW MID LEVEL CLOUDS WILL ACCOMPANY THE FRONT...WITH CLEARING DURING THE AFTERNOON. HIGH SURFACE PRESSURE WILL BUILD ACROSS THE MISSOURI RIVER VALLEY TUESDAY...WHILE BROAD CYCLONIC FLOW CENTERED OVER THE EASTERN GREAT LAKES WILL BRING NORTHWEST WINDS THE THE LOWER OHIO VALLEY. ALTHOUGH SOME FLAT CU MAY DEVELOP DURING THE AFTERNOON OVER THE BLUEGRASS...EXPECT MOSTLY CLEAR SKIES. WILL CONTINUE TO USE THE COOLER RAW MODEL TEMPERATURES OVER THAT OF MOS GUIDANCE. FOR MONDAY AND TUESDAY. TUESDAY WILL BE THE FIRST DAY THIS FALL WITH WIDESPREAD HIGHS IN THE 60S. .WEDNESDAY THROUGH FRIDAY... A SLOWLY PROGRESSIVE BUT AMPLIFIED PATTERN ALOFT WILL CONTINUE DRY NORTHWEST FLOW ACROSS THE COMMONWEALTH. IN THIS AMPLIFIED PATTERN THE SURFACE RIDGE AXIS...WEST OF US ON TUESDAY WILL ONLY VERY SLOWLY MOVE ACROSS EASTERN KENTUCKY BY THURSDAY AFTERNOON. CLASSIC OCTOBER-LIKE WEATHER MAY BE EXPECTED WEDNESDAY AND THURSDAY WITH LIGHT WINDS...CLEAR SKIES...MILD DAYS AND COOL NIGHTS. OUR COLDEST MORNING WITH CALM WINDS SHOULD BE WEDNESDAY. SOME OF OUR NORMALLY COOLER LOCATIONS SUCH AS MARROWBONE AND LEXINGTON INDIANA MAY FALL INTO THE LOWER 40S. && .AVIATION (06Z TAFS)... LOW LEVEL SOUTHERLY FLOW WILL CONTINUE TO BRING PLENTIFUL MOISTURE INTO THE LOWER OHIO VALLEY IN THE FIRST 12 HOURS OF THE FORECAST PERIOD. SURFACE OBS AND SATELLITE PICTURES INDICATED IFR CONDITIONS JUST TO THE WEST OF THE TAF SITES UNDER MOSTLY CLEAR SKIES. THE FEELING NOW IS THAT THE MID LEVEL CLOUDS OVER THE AREA WILL CLEAR AND CONDITIONS WILL DROP INTO THE IFR RANGE ESPECIALLY AT SDF AND BWG. BEST CHANCE FOR PRECIPITATION WILL BE OVER THE LEX TAF SITE BY 12Z AND AGAIN LATE IN THE DAY ACROSS ALL THE AREA. && .LMK WATCHES/WARNINGS/ADVISORIES...
