The episode as NWS LMK wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
110 PM EDT SUN MAY 2 2010
...UPDATED AVIATION DISCUSSION...
...FORECAST UPDATE...
THE TORNADO WATCH FOR THE EASTERN BLUEGRASS AND THE LAKE CUMBERLAND
REGIONS HAS EXPIRED. NO ADDITIONAL SEVERE WEATHER IS EXPECTED THIS
AFTERNOON.
OUR ATTENTION IS SOLELY FOCUSED ON WHAT IS DEVELOPING
INTO AN EXTENSIVE FLOODING EVENT. BOTH THE 12Z NAM AND THE 12Z GFS
HINTED AT RAIN RE-DEVELOPING TO THE WEST OF THE BACK EDGE OF THE
LINE OF CONVECTION...AND THAT IS WHAT HAS HAPPENED. EXPECT STEADY
MODERATE RAIN THROUGH AT LEAST MID-AFTERNOON TO THE EAST OF AN OHIO
COUNTY TO WASHINGTON COUNTY INDIANA LINE. ONLY A FEW COUNTIES IN
SOUTHWESTERN INDIANA WILL SEE SCATTERED PRECIPITATION.
ANOTHER INCH OR SO IS FORECAST FROM MID-MORNING ON ALONG THE OHIO
RIVER...WITH UP TO ANOTHER 2 INCHES OR MORE ACROSS CENTRAL KENTUCKY
AND THE BLUEGRASS REGION. THIS WILL EXASPERATE AN ALREADY BAD
FLOODING SITUATION. AS STEADY RAIN CONTINUES...FLASH FLOODING
EARLIER THIS MORNING WILL TRANSITION INTO A WIDESPREAD FLOODING
EVENT AS MODERATE AND MAJOR RIVERS RISE. PAY ATTENTION TO OUR LATEST
RIVER FORECASTS FOR EXPECTED CRESTS OVER THE NEXT SEVERAL DAYS.
.SHORT TERM (TODAY AND TONIGHT)...
...EXCESSIVE RAINFALL WITH LIKELY FLOODING AS WELL AS A SEVERE
WEATHER EPISODE TODAY...
LATEST RUC MESOANALYSIS AT 06Z INDICATED SURFACE LOW AT THE
CONFLUENCE OF AR/MO/IL/KY/TN AND CONTINUING TO RIDE NORTHEASTWARD
ALONG SURFACE FRONTAL BOUNDARY. WARM FRONTAL BOUNDARY WILL BE LIFTING
NORTHWARD ACROSS THE AREA OVER THE NEXT COUPLE OF HOURS...INCREASING
THE LIKELIHOOD OF SEVERE WEATHER...INCLUDING DAMAGING WINDS AND
TORNADOES. BIGGEST IMPACTS ARE STILL EXPECTED TO BE FROM FLASH
FLOODING AS THE MAIN WAVE OF RAIN MOVES IN TOWARD DAWN AND LASTS FOR
MOST OF THE DAY. FRONTAL BOUNDARY WILL FINALLY PUSH THROUGH AS A
COLD FRONT LATER TODAY WITH RAIN ENDING IN THE EAST BY TONIGHT. WITH
HEAVY RAINFALL FROM FRIDAY NIGHT THROUGH SATURDAY...AND THE EXPECTED
ADDITIONAL RAINFALL OF 2 TO 4 INCHES THE REST OF TODAY...FLASH
FLOODING SEEMS LIKELY. WITH CONTINUED MOISTURE STREAMING IN FROM THE
GULF ON A 60 KNOT LLJ...PWATS APPROACHING 2 INCHES THROUGH THE
COLUMN AND UPPER 60S TO LOWER 70S TD/S STREAMING IN THUNDERSTORMS
SHOULD BE VERY EFFICIENT WITH RAINFALL AND COULD PRODUCE RAINFALL
RATES OF 1 TO 2 INCHES PER HOUR. IN LOCATIONS THAT SEE TRAINING
THUNDERSTORMS...A PARTICULARLY DANGEROUS FLASH FLOODING SCENARIO
WILL EXIST.
CURRENT ENVIRONMENT IS ELEVATED...HOWEVER WITH THE ADVANCEMENT OF
THE WARM FRONT NORTHWARD OVER THE NEXT COUPLE OF HOURS...THE
POTENTIAL FOR MORE SURFACE BASED STORMS WILL INCREASE...ALONG WITH
DAMAGING WIND/TORNADO THREAT. ENVIRONMENT IS HIGHLY DYNAMIC WITH
GOOD SPEED AND DIRECTIONAL SHEAR CONDUCIVE FOR SUPERCELLS/BOWING
SEGMENTS/LEWP STRUCTURES. FORECAST SOUNDINGS INDICATE LARGE LOOPING
HODOGRAPHS JUST BEFORE DAWN WITH STORM RELATIVE HELICITY VALUES
ABOVE 300 M2/S2. A TORNADO WATCH IS IN EFFECT FOR THE WESTERN THIRD
OF THE CWA UNTIL 5AM...HOWEVER MONITOR THE LATEST UPDATES FOR
EXTENSIONS OR NEW TORNADO WATCH ISSUANCES.
OTHERWISE...TEMPERATURES SHOULD REMAIN FAIRLY STEADY AND ONLY RISE
INTO THE MID 70S THIS AFTERNOON ON STRONG WAA. HEAVY CLOUD COVER AND
RAINFALL SHOULD KEEP TEMPS DOWN A BIT.
THE LONG TERM PORTION OF THE FORECAST WAS NOT UPDATED WITH THIS
PACKAGE DUE TO THE ONGOING WEATHER THREAT.
.LONG TERM (MONDAY - SUNDAY)...
CONSENSUS IS BUILDING THAT THIS UPCOMING WORK WEEK WILL SEE A VAST
IMPROVEMENT OVER OUR WET DERBY WEEKEND. EXPECT A MAINLY DRY AND WARM
WEEK WITH OUR ONLY REAL CHANCES OF RAIN ARRIVING MONDAY EVENING AND
FRIDAY.
THE FORECAST UPPER AIR PATTERN ON MONDAY INDICATES A WEAKENING
POSITIVELY TILTED TROUGH CENTERED OVER THE SOUTHERN PLAINS. A STRONG
JET WILL HAVE EXITED THE BASE OF THIS TROUGH BY THIS TIME...AND WILL
EXTEND FROM TEXAS THROUGH NEW ENGLAND. MORE IMPORTANTLY...THE AXIS
OF VERY HIGH PRECIPITABLE WATER RESPONSIBLE FOR SUNDAY'S HEAVY RAINS
WILL HAVE SAGGED SOUTHEAST ACROSS EASTERN TENNESSEE AND WEST
VIRGINIA. AS DRIER AIR WORKS ITS WAY ACROSS THE COMMONWEALTH DURING
THE DAY...EXPECT AT LEAST PARTIALLY CLEARING SKIES WITH ANY
LINGERING RAIN ACROSS OUR SOUTHEASTERN COUNTIES ENDING DURING THE
MORNING HOURS. BY LATE MONDAY...SOME SCATTERED SHOWERS MAY DEVELOP
DURING THE AFTERNOON OR EVENING HOURS ACROSS SOUTHERN INDIANA AND
NORTHERN KENTUCKY AS THE AXIS OF THE ABOVE MENTIONED 500MB TROUGH
MOVES ACROSS THE OHIO RIVER.
BY EARLY WEDNESDAY...UPPER AIR FLOW WILL BECOME ZONAL ACROSS THE
CONUS AS A STRONG JET MOVES ASHORE ACROSS THE PACIFIC NORTHWEST.
MILD WESTERLY FLOW WILL MOVE ACROSS THE LOWER OHIO VALLEY WEDNESDAY
THROUGH EARLY FRIDAY. AT THE SURFACE...EXPECT LIGHT WINDS WEDNESDAY
AS HIGH PRESSURE MOVES OVERHEAD. SOUTHERLY FLOW WILL DEVELOP
THURSDAY AS HIGH PRESSURE BECOMES ESTABLISHED ACROSS OUR
SOUTHEASTERN STATES. MOSTLY SUNNY SKIES AND WARM TEMPERATURES IN THE
MID 70S TO THE LOWER 80S ARE EXPECTED WEDNESDAY AND THURSDAY.
THE ZONAL UPPER AIR PATTERN IS EXPECTED TO BEGIN TO AMPLIFY EARLY
FRIDAY AS LOW PRESSURE IS FORECAST TO DEVELOP ACROSS THE LOWER
MISSOURI VALLEY. THIS WILL DEEPEN AS IT MOVES TOWARDS THE GREAT
LAKES LATE IN THE DAY. SHOWERS AND THUNDERSTORMS MAY ACCOMPANY A
PRETTY STOUT COLD FRONT FRIDAY AS IT MOVES SOUTHEAST ACROSS THE OHIO
RIVER. HIGH PRESSURE WILL BUILD SOUTHEAST TOWARDS THE LOWER OHIO
VALLEY EARLY SATURDAY. THIS WILL BRING DISTINCTLY COLDER
TEMPERATURES FOR NEXT WEEKEND.
&&
.AVIATION (18Z TAF ISSUANCE)...
WIDESPREAD RAIN WITH EMBEDDED THUNDERSTORMS WILL KEEP ALL TAF SITES
IN MVFR VISIBILITIES AND CEILINGS THROUGH AT LEAST 22Z FOR SDF AND
CONSIDERABLY LONGER FOR LEX AND BWG.
RAIN WILL TAPER OFF AT SDF AFTER AROUND 00Z WITH CEILINGS RISING
ABOVE VFR THRESHOLDS AROUND THE 08Z TO 10Z THRESHOLD.
AT LEX...SHOWERS AND EMBEDDED THUNDERSTORMS WILL CONTINUE THROUGH
06Z...WITH VFR CIGS ARRIVING AFTER 12Z.
AT BWG...EXPECT MVFR CIGS AND VISIBILITIES IN SHOWERS AND EMBEDDED
THUNDERSTORMS THROUGH THE 02 TO 05Z TIME FRAME...WITH CEILINGS
RISING TO VFR AFTER 09Z.
CLEAR TO PARTLY CLOUDY SKIES AND SOUTHWESTERLY WINDS OF 5 TO 10 MPH ARE
EXPECTED AFTER 14Z MONDAY.
SOUTH WINDS OF 10 TO 15 MPH WILL CONTINUE UNTIL A COLD FRONT MOVES
EAST OF THE REGION EARLY THIS EVENING. AT SDF...WINDS WILL
WEAKEN...THEN SWITCH TO THE WEST AROUND 03Z. AT BWG AND LEX...THIS
WIND SWITCH WILL OCCUR A COUPLE OF HOURS LATER AROUND 05Z.
