Hail and Damaging Wind in Indiana, August 28, 2005

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
115 PM EDT SUN AUG 28 2005

...REMNANTS OF KATRINA LIKELY TO IMPACT CWA WITH HVY RAIN/WIND...

.SHORT TERM (TONIGHT-MONDAY)...
ISLTD-SCT TSRA HAVE BEEN DEVELOPING WITHIN MOIST AND UNSTABLE
AIRMASS OVER THE CWA THIS AFTN. VISIBLE SATELLITE SHOWS CLOUDS HAVE
GOOD TEXTURE TO THEM...INDICATIVE OF HEALTHY VERTICAL DEVELOPMENT. A
COUPLE CELLS HAVE BECOME SOMEWHAT STRONG. LOCALLY HVY RAINS AND
GUSTS TO 40 MPH POSSIBLE NEAR STRONGER CELLS. CELLS ARE TRAINING IN
SPOTS...WHERE A COUPLE INCHES ARE POSSIBLE. WILL CONTINUE SCT TSRA
INTO THE EVE HOURS OVER THE CWA. BEST CHANCES SHOULD BE OVER SRN/ERN
KY WHERE GFS IS INDICATING A BAND OF SLIGHTLY ENHANCED LIFT...WILL
HAVE POPS 40-50% HERE.

BOTH MODELS ARE THEN ADVERTISING A SECOND AREA OF LIFT BY 12 UTC
MONDAY...WITHIN ZONE OF SHARP ANTICYCLONIC FLOW ALOFT POLEWARD OF
HRCN KATRINA. THE NAM IS FOCUSING THIS LIFT OVER SRN/ERN KY...WHILE
THE GFS IS FURTHER NORTH CLOSER TO THE OHIO RIVER. WITH THIS IN
MIND...WILL START ANOTHER ROUND OF CHC POPS AFTER 8/9 UTC...KEEPING
THE BETTER CHANCES OVER DOWNSTATE KENTUCKY. THERE COULD BE A
RELATIVE LULL IN PCPN COVERAGE FROM LATE MORNING INTO EARLY AFTN
MONDAY...AS BAND OF SUBSIDENCE OVERSPREADS THE CWA. IF THIS FEATURE
IS REALIZED...THEN WE COULD SEE TEMPS WARM INTO THE UPPER 80S OVER
MUCH OF THE CWA (PARTICULARLY LOU/SRN IND ZONES). CURRENT FCST
HANDLES THIS WELL.

MORE APPRECIABLE RAIN ASSOC WITH ENHANCED DEFORMATION ZONE LOOKS TO
MOVE INTO THE CWA SOMETIME MONDAY EVENING. SEE LONG TERM SECTION.

FCST BUFKIT SOUNDINGS INDICATE DECENT POTENTIAL FOR FOG OVERNIGHT
AND EARLY MONDAY MORNING...WITH VERY LITTLE BOUNDARY LAYER MIXING
AND DECENT MOISTURE. RUC AND MOS GUIDANCE ARE NOT SO ROBUST IN
DEVELOPING FOG. WILL MENTION AT LEAST PATCHY FOG FOR NOW...AND TAKE
VSBYS DOWN INTO IFR RANGE AT BWG...MVFR AT SDF AND LEX. CS

.LONG RANGE (MON NIGHT-SUNDAY)...
CURRENT INDICATIONS POINTING TOWARD A HIGH IMPACT EVENT FOR THE CWA
MON NIGHT THROUGH WEDNESDAY. FOLLOWING TPC FORECAST SHOWING CYCLONE
INTERACTING WITH LARGE UPPER TROF OVER GREAT LAKES...TRANSLATING
NEWD ACROSS THE TENN/OHIO VALLEYS. GFS/ECMWF CONSISTENT IN TRACK...
THOUGH MOST RECENT ECMWF IS A FEW HOURS SLOWER THAN GFS. DEFORMATION
BAND OF TSRA EXPECTED TO MOVE NORTHWARD INTO THE CWA SOMETIME MON
EVENING...WITH A SHARP NORTHERN EDGE TO THE PRECIP SHIELD GIVEN THE
OMEGA DISTRIBUTIONS. SECOND SHOT OF INTENSE LIFT MOVES INTO THE
REGION DURING THE DAYTIME TUESDAY...LASTING INTO TUE NIGHT AND WED
MORNING GIVEN THE SLOWER SOLUTIONS DEPICTED BY TPC/ECMWF. HAVE
BUMPED POPS INTO LIKELY-CATEGORICAL LEVELS FOR THIS PERIOD.

SO BASICALLY FROM MON NIGHT-WED MORNING...HVY RAINFALL IS A GOOD
POSSIBILITY WITHIN HIGH PRECIP EFFICIENCY ENVIRONMENT. AVERAGE
RAINFALL AMOUNTS OF 2 TO 3 INCHES SEEM REASONABLE...THOUGH WE COULD
SEE LOCALLY HIGHER AMOUNTS NEAR FIVE INCHES. 6 HOUR FLOOD GUIDANCE
VALUES ARE AROUND 3 TO 3.5 INCHES...SO WE COULD SEE SOME LOCALIZED
FLOODING DURING PASSAGE OF CYCLONE. WILL ISSUE A HYDROLOGIC OUTLOOK
(ESFLMK) THIS AFTN.

SOMETHING ELSE THAT IS BECOMING MORE APPARENT IS THAT AS HRCN HAS
STRENGTHENED NOW TO CAT 5...IT WILL TAKE SOME TIME TO WIND DOWN ONCE
OVER LAND...SO WE COULD BE DEALING WITH TROPICAL STORM FORCE WIND
GUSTS MON NIGHT THROUGH TUE NIGHT TIMEFRAME. IN FACT...TPC HAS
KATRINA AT 35 KT RIGHT OVER THE CWA AT 06 UTC WED. BUFKIT DATA FROM
GFS INDICATE A BAND OF NEAR 50 KT WINDS AROUND 6KFT...WHICH COULD
ALSO TRANSLATE DOWNWARD IN HEAVIER TSRA. WILL HIGHLIGHT POTENTIAL
FOR THESE WINDS IN A SPECIAL WX STATEMENT...BUT I WOULD ADD THAT
LATER SHIFTS MAY NEED TO CONSIDER AN INLAND TROPICAL STORM WIND
WATCH FOR PARTS OF THE CWA. NEIGHBORING WFOS IN TENNESSEE HAVE
ALREADY ISSUED THEM.

AS PREVIOUS FCSTR MENTIONED AND AS IS TYPICALLY WITH LANDFALLING
TROPICAL SYSTEMS...FCST WIND FIELDS ARE FAVORABLE FOR SOME ISLTD
TORNADOES IN LOW-TOPPED CELLS TUE-TUE NIGHT. BUFKIT 1KM SRH VALUES
NEAR 295...IMPRESSIVE. BEST CHANCES FOR THIS WOULD BE TO THE
EAST/NORTH OF THE SFC CYCLONE TRACK.

AFTER REMNANTS OF KATRINA DEPART SOMETIME WED NIGHT...A GENERAL
TROFINESS WILL REMAIN OVER THE REGION. DEEP LEVEL MOISTURE IS
SCOURED OUT WITHIN A LIGHT NLY FLOW PATTERN...BUT MODELS DO SHOW
SOME RESIDUAL 850MB MOISTURE SUGGESTIVE OF AT LEAST DIURNAL CU EACH
DAY THU-SUN. TEMPERATURES WILL BE AROUND TO SLIGHTLY BELOW SEASONAL
NORMALS DURING THIS LATER HALF OF THE EXTENDED PERIOD. LOWERED FCST
DEWPOINTS AS WELL THU-SUN...CONSISTENT WITH ENSEMBLE MOS MEANS. CS

.LMK WATCHES/WARNINGS/ADVISORIES...
IN...NONE.
KY...NONE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTH CENTRAL
INDIANA AND CENTRAL KENTUCKY.

.DAY ONE...REST OF THIS AFTERNOON AND TONIGHT.

SCATTERED THUNDERSTORMS WILL CONTINUE AS A WEAK FRONTAL BOUNDARY
MOVES INTO THE OUTLOOK AREA THROUGH THE EVENING HOURS. THE BEST
CHANCES FOR STORMS WILL BE IN CENTRAL AND SOUTHERN KENTUCKY. NO
SEVERE STORMS ARE EXPECTED AT THIS TIME...HOWEVER ANY CELLS COULD
PRODUCE GUSTY WINDS TO 35 OR 40 MPH AND VERY HEAVY RAINS. ISOLATED
SPOTS COULD PICK UP A COUPLE INCHES OF RAIN.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.

NUMEROUS THUNDERSTORMS ARE FORECAST AT TIMES MONDAY THROUGH
WEDNESDAY AS THE REMNANTS OF HURRICANE KATRINA ARE EXPECTED TO MOVE
INTO THE OHIO RIVER VALLEY. STRONG GUSTY WINDS AND LOCALLY HEAVY
RAINFALL WILL BE THE BIGGEST THREATS...ESPECIALLY ON TUESDAY AND
TUESDAY NIGHT. WIDESPREAD RAINFALL AMOUNTS OF 2 TO 3 INCHES ARE
LIKELY...WITH ISOLATED AMOUNTS NEAR 5 INCHES. THIS MAY RESULT IN
LOCALIZED FLOODING. WIND GUSTS MAY REACH 40 MPH OVER MUCH OF THE
OUTLOOK AREA. ISOLATED SEVERE STORMS ARE POSSIBLE AS WELL DURING
THIS PERIOD...WITH DAMAGING WINDS THE MAIN THREAT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED TUESDAY AND TUESDAY NIGHT.
