AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
743 AM EDT WED MAY 12 2010

...UPDATED AVIATION DISCUSSION...

.SHORT TERM (TODAY AND TONIGHT)...

AT 06Z QUASISTNRY FRONT WAS POSITIONED FROM SRN INDIANA (S OF BMG)
NEWD TO NEAR CVG. TSTMS (FOCUSED ON THE BNDRY) UPSTREAM...CONTD TO
DEVELOP ACRS SCNTRL/CENTRAL MO. THESE STORMS SHUD CONTINUE TO
DEVELOP/MOVE ENE IN UPR LEVEL SW DIFFLUENT FLOW AHEAD OF WEAK SHRTWV
TROF BEING EJECTED AHEAD OF WRN U.S. TROF. AN AMBIENT RELATIVELY
MOIST/UNSTABLE AMS IS IN PLACE...ESPECIALLY UPSTREAM...WHERE AN
INCREASING MODERATE LOW LEVEL JET IS HELPING TO INITIATE STORMS.

THE GREATEST CONCENTRATION OF STORMS TDA SHUD BE FOCUSED NEAR THE
BNDRY FROM OUR NRN MOST INDIANA COUNTIES EWD INTO THE NRN BLUEGRASS
REGION OF KY...NORTH OF A LOUISVILLE TO LEXINGTON LINE. WITH THE
SFC/LOW LEVEL BNDRY PARRALLELING THE UPR FLOW...THERE SHUD BE
TRAINING/HEAVY RAIN PRODUCING CELLS.

WILL INCREASE POPS TO HIGH LIKELY ACRS OUR NRN MOST COUNTIES AND
TAPER DOWN SWD TO OUR CURRENT 30 POPS ACRS SCNTRL KY...DURG THE
MORNING HRS. WILL INSERT HEAVY RAIN IN THE NORTH AS WELL.

SCT TO NUMEROUS TSTMS SHUD BE EXITING OUR FA TO THE E/NE DURG THE
AFTN AS UPR LEVEL RIDGE BUILDS FROM THE S/SHRTWV EXITS TO OUR E.
WILL LEAVE LOW CHC POPS IN FOR TNGT ACRS PRIMARILY OUR NERN QUADRANT
WITH BNDRY STILL IN THE VCNTY.

.LONG TERM (THURSDAY - TUESDAY)...

THE LONG TERM PATTERN FEATURES SEVERAL CHANCES OF RAIN AS A
PROGRESSIVE ENERGETIC LONG WAVE PATTERN CONTINUES OVER THE CONUS.
WITH SO MANY ENERGY WAVES IN THE 7 DAY PERIOD...FORECAST CONFIDENCE
DROPS OFF QUICKLY AS MODEL TIMING DEGRADES ON DAY 4 AND BEYOND.
THEREFORE...HAVE TRIED TO MAKE MINOR ADJUSTMENTS AND TREND TOWARD
THE LATEST MODEL CONSENSUS ON TIMING ESPECIALLY FOR DAYS 4-7.

THURSDAY - SATURDAY...

THURSDAY WE/LL SIT IN THE WARM SECTOR OF A SFC LOW MOVING INTO THE
GREAT LAKES REGION.  WE/LL SEE PLENTY OF WAA AND MOISTURE ADVECTION
INTO THE REGION.  HIGHS WILL LIKELY TOP OUT IN THE MID TO UPPER
80S...WITH DEWPT APPROACHING THE MID TO UPPER 60S.  CONVECTION
SHOULD STAY FOCUSED TO OUR NORTH AND WEST BUT CAN/T RULE OUT A STORM
OR TWO OVER SOUTHERN INDIANA AND A PORTION OF THE
BLUEGRASS...THEREFORE HAVE CONTINUED THE 20% POP.

THURSDAY NIGHT PRECIPITATION CHANCES WILL INCREASE AS THE SFC LOW
MOVES ENE OVER THE GREAT LAKES REGION PUSHING A COLD FRONT THROUGH
OUR REGION. WILL RELY ON A COMBO THE 0Z OP GFS AND GFS ENSEMBLES FOR
FROPA WHICH SHOULD OCCUR DURING THE MORNING HOURS OF FRIDAY.  FELT
CONFIDENT ENOUGH WITH PRECIP CHANCES TO UP TO 55% POPS FOR FRIDAY.
ALTHOUGH DIURNAL TIMING ISN/T THE BEST FOR STORMS DUE TO LIMITED
SFC INSTABILITY...MODEL SOUNDINGS INDICATE PLENTY OF ELEVATED CAPE
AVAILABLE.  50-60 KT MID LEVEL WIND FIELDS AS WELL AS STEEP MID
LEVEL LAPSE RATES ARE IN SUPPORT OF LARGE HAIL AND POSSIBLY DAMAGING
WINDS.  THIS THREAT WILL MAINLY EXIST FRIDAY MORNING.  WEAKER
CONVECTION MAY LINGER BEHIND THE FRONT FRIDAY AFTERNOON WITH EVEN
LESSER CHANCES FRIDAY NIGHT.

THE FORECAST FOR SATURDAY AND BEYOND BECOMES QUITE TRICKY AS MODELS
DIVERGE ON TIMING FROM RUN TO RUN.  FOR NOW HAVE LEFT A SLIGHT
CHANCE FOR PRECIP IN THE SOUTH ON SATURDAY AS THE 12Z ECMWF SUGGESTS
ALONG A LINGERING BOUNDARY.  HOWEVER...THE LATEST GFS RUNS INDICATE
SFC HIGH PRESSURE AND UPPER LEVEL RIDGING WILL PUSH THE BOUNDARY
WELL SOUTH OF THE AREA AND CONDITIONS WILL BE DRY FOR SATURDAY.
WILL CONTINUE TO MONITOR OVER THE NEXT FEW RUNS.  ONE THING THAT IS
FOR SURE ON SATURDAY IS THAT HIGH TEMPS WILL BE COOLER BEHIND THE
FROPA...MID 70S FOR HIGHS.

SUNDAY - TUESDAY...

THE LATEST MODEL RUNS HAVE SLOWED THE NEXT POTENT SHRT/WV TO AFFECT
THE AREA.  THE LATEST TIMING IS MAINLY LATE SUNDAY NIGHT AND
MONDAY.  HAVE TRENDED POP TIMING BACK TO REFLECT THIS.  THE NEXT
OBSTACLE WILL BE HOW QUICK TO CLEAR OUT THE SYSTEM...THE ECMWF AND
GFS DIVERGE GREATLY ON THIS SO WILL NOT CHANGE THE FORECAST FOR
TUES...LOW POPS WILL REMAIN.  TEMPS WILL REMAIN SEASONAL FOR THIS
TIME OF YEAR FOR THE FIRST HALF OF NEXT WEEK.

.AVIATION (12Z TAF ISSUANCE)...

QUASISTNRY FRONT SET UP FROM SRN INDIANA INTO THE NRN BLUEGRASS
REGION OF KY DURG THE PERIOD. THIS IS WHERE THE MOST ACTIVE WX
(TSTMS) WILL BE. STORMS DEVELOPING UPSTREAM ALONG/JUST NORTH OF THE
BNDRY...WITH THE AID OF AN INCREASING/MODEST LOW LEVEL JET...WILL
MOVE/DEVELOP EWD THIS MORNING AND AFFECT PRIMARILY SDF AND LEX
RESULTING IN MVFR CONDITIONS. SHUD THE CORE OF A STORM MOVE DIRECTLY
OVER A SITE...BRIEF LIFR/IFR CONDITIONS ARE POSSIBLE IN HEAVY
RAIN...THOUGH THE HEAVIEST BANDS OF RAIN/STORMS SHUD SET UP NORTH OF
A SDF TO LEX LINE. MODESTLY STRONG S/SW FLOW WILL FEED INTO THE
BNDRY...THIS MOST NOTED AT BWG TDA WITH GUSTY SW WINDS.

MOST OF THE ACTIVITY SHUD BE DEPARTING TO THE EAST BY MID
