AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
120 PM EDT WED MAY 4 2011

...UPDATED AVIATION DISCUSSION...

...FORECAST UPDATE...

COMPACT SHORTWAVE CONTINUES TO MOVE ACROSS PORTIONS OF THE OHIO
VALLEY THIS MORNING.  MUCH OF OUR CENTRAL AND EASTERN SECTIONS ARE
CAUGHT IN THE DEEP THERMAL TROUGH.  THIS COMBINED WITH NORMAL
INSOLATION HAS RESULTED IN QUITE A BIT OF LOW CLOUDS...SPRINKLES AND
HAZE IN AREAS NORTHEAST OF A LINE FROM LOUISVILLE TO SOMERSET
KENTUCKY.  ALL OF THE GUIDANCE SUGGESTS THAT THIS WILL SLOWLY MOVE
EAST THIS AFTERNOON AND BEGIN TO BREAK UP.  FOR THIS FORECAST
UPDATE...HAVE INCREASED CLOUDS SIGNIFICANTLY IN THE EAST AND
NORTHEAST SECTIONS ALONG WITH ADDING SCATTERED SPRINKLES AND HAZE.
FEEL THAT MUCH OF THIS WILL END BY EARLY AFTERNOON.  ALSO HAVE
UPDATED HOURLY TEMPS TO REFLECT THE COOLER READINGS IN THE
NORTHEAST...AND TO LOWER AFTERNOON TEMPS THERE AS WELL.
TEMPERATURES IN THE BLUEGRASS WILL LIKELY STAY IN LOWER-MID 40S THIS
MORNING AND THEN BEGIN TO RISE IN THE AFTERNOON ONCE THE CLOUD DECK
BREAKS UP.

.SHORT TERM (TODAY AND TONIGHT)...

UPPER LEVEL TROF POSITIONED OVER THE OHIO VALLEY ATTM. ASSOCIATED
SURFACE TROF EXTENDS FROM NEAR CVG TO JUST WEST OF LEX TO NEAR
GLASGOW. POST TROF NW WINDS AND DRIER AIR SEEN IN OBS BEHIND TROF.
BWG DEVELOPED DENSE FOG BRIEFLY THEN QUICKY DISSIPATED WITH TROF
PASSAGE. GLASGOW SHOWING SIMILAR FOG TRENDS. DEBATED ON DENSE FOG
ADVISORY FOR OUR FAR E/SE COUNTIES BORDERING JKL AND OHX...WHERE
ADVISORIES HAVE BEEN POSTED. CURRENT WEBCAMS JUST SHOWING SOME LIGHT
FOG ACRS OUR SERN COUNTIES ATTM AND THINK WITH TROF APPROACHING...
PRE TROF FOG DEVELOPMENT WILL BE BRIEF AND ON THE WANE TOWARD
SUNRISE. WILL HOWEVER MONITOR AND MAY NEED TO ISSUE AN ADVISORY IN
THE NEXT 1-3 HRS.

LOW CLOUDS WILL DEVELOP/MOVE IN TODAY FOR MOST AREAS...WITH OUR SWRN
COUNTIES TO SEE THE MOST SUN AS HIGH PRES/UPPER LEVEL RIDGE BUILD IN
TDA AND TNGT. CLOUDS WILL HOLD TEMPS DOWN A BIT...ESPECIALLY ACRS
SERN INDIANA AND THE BLUEGRASS REGION OF KY (MID 50S). FROST
POTENTIAL THERE FOR TGNT...ESPECIALLY OVER OUR ERN KY COUNTIES/SERN
INDIANA AS HIGH PRES MOVES DIRECTLY OVERHEAD/SKIES CLEAR/WINDS GO
LIGHT TO CALM. CONCERNED HOWEVER ABOUT WARM GROUND TEMPS. WILL DEAL
WITH A POTENTIAL FOG HEADLINE IN THE NEAR TERM AND LET THE DAY SHIFT
BETTER PINPOINT THE NEED/AREA FOR A FROST HEADLINE FOR EARLY THU
MORNING.

WILL LEAVE CURRENT AREAL FLOOD WARNINGS AS IS FOR NOW...WHILE RIVER
FLOODING HAS CEASED AT DEPUTY ON THE MUSCATATUCK. WILL LIKELY BE
ABLE TO DROP MOST AREAL FLOOD WARNINGS LATER TODAY AND DROP BLUE
LICKS SPRING FROM THE RIVER FLOOD CATEGORY.

.LONG TERM (THURSDAY - TUESDAY)...

THURSDAY-FRIDAY NIGHT...

SURFACE HIGH PRESSURE WILL BE CENTERED OVER THE REGION DURING THE
MORNING HOURS THURSDAY. THIS SYSTEM WILL SLIDE OFF TO THE EAST AS
OUR NEXT WEATHER SYSTEM APPROACHES FROM THE NORTHWEST FOR FRIDAY.
UNTIL THEN...EXPECT DRY CONDITIONS AND GENERALLY CLEAR SKIES
THURSDAY AND THURSDAY EVENING. AS THE HIGH SLIDES EAST WINDS WILL
BECOME SOUTHERLY THROUGH THE DAY THURSDAY AND PROVIDE A WARM-UP INTO
THE MID AND UPPER 60S...PERHAPS 70 IN THE SOUTH AND IN URBAN AREAS.

OUR NEXT WEATHER SYSTEM WILL SWING ACROSS THE MIDWEST IN NORTHWEST
FLOW ALOFT AND DRAG A COLD FRONT ACROSS OUR FORECAST AREA LATE
THURSDAY NIGHT INTO FRIDAY. RAIN SHOWERS WILL SPREAD ACROSS THE
AREA...WITH THE BEST CHANCES ACROSS THE NORTHERN FORECAST AREA. WITH
COLD TEMPERATURES ALOFT CREATING DECENT LAPSE RATES AND SREF
PROBABILITIES INDICATING A CHANCE OF NEGATIVE LI/S....A FEW
ISOLATED STORMS MAY BE POSSIBLE. WILL KEEP LOW CHANCE POPS ACROSS
THE NORTH AND SLIGHT CHANCE POPS ACROSS THE SOUTH. EXPECT IMPROVING
CONDITIONS THROUGH FRIDAY AFTERNOON AS THE FRONT QUICKLY PUSHES
EAST. THIS IS EVIDENT IN TIME-HEIGHT PROJECTIONS...AS THEY
ILLUSTRATE CLEARING FROM WEST TO EAST FRIDAY AFTERNOON.

AS FOR TEMPERATURES...EXPECT FRIDAY MORNING TEMPS GENERALLY IN THE
MID AND UPPER 40S AND HIGHS IN THE MID TO UPPER 60S. ONCE AGAIN...A
FEW LOCATIONS COULD REACH 70 AS THE WINDS BACK TO MORE SOUTHWESTERLY
THROUGH THE AFTERNOON.

SATURDAY-SUNDAY...

THE LATEST GFS AND ECMWF CONTINUE TO DIFFER ON THE SATURDAY WEATHER
SYSTEM. THE GFS IS A LITTLE STRONGER WITH THE MID-LEVEL
TROUGH...WHILE THE ECMWF IS WEAKER. FOR NOW...WILL LEAN TOWARD THE
ECMWF...GEFS...AND NAEFS SOLUTION...WITH A LITTLE OF THE GFS TIMING
THROWN IN. THIS WILL YIELD THE BEST CHANCE OF PRECIPITATION /STORMS/
SATURDAY AFTERNOON AND EVENING. THIS IS COINCIDENT WITH THE COLD
FRONTAL PASSAGE OF THIS SYSTEM. GUIDANCE CONTINUES TO INDICATE THE
BEST RAIN CHANCES REMAIN ACROSS OUR NORTHERN FORECAST AREA SATURDAY
AFTERNOON. THE FRONT APPEARS TO STALL ACROSS SOUTHERN KENTUCKY. THIS
COULD PROLONG RAIN CHANCES INTO SUNDAY ACROSS THE ENTIRE FORECAST
AREA...BUT MORE NOTABLY ACROSS THE NORTHEAST. WILL KEEP CHANCE POPS
ACROSS MOST OF THE FORECAST AREA SATURDAY NIGHT...THEN JUST SLIGHT
CHANCE ACROSS THE NORTHEAST SUNDAY MORNING. AS PREVIOUSLY
MENTIONED...THE RAIN CHANCES MAY NEED TO BE INCREASED ACROSS THE
ENTIRE FORECAST AREA SUNDAY...WILL CONTINUE TO MONITOR MODEL TRENDS.

AS FOR TEMPERATURES...IT WILL BE WARM SATURDAY WITH HIGH TEMPS
GENERALLY IN THE MID 70S AIDED BY BREEZY SOUTHWESTERLY WINDS.
OVERNIGHT LOWS SHOULD RANGE IN THE MID TO UPPER 50S. SUNDAY MAX
TEMPERATURES WILL BE A TOUCH FORECAST. IF THE STALLED FRONT RETREATS
NORTHWARD AS A WARM FRONT...TEMPS WILL REACH THE MID AND UPPER 70S.
HOWEVER...IF THE STALLED FRONT TAKES LONGER TO PUSH THROUGH THE AREA
AND PRECIP CHANCES /CLOUDS/ LINGER INTO SUNDAY...THEN THIS WILL
LIKELY KEEP TEMPS DOWN.

MONDAY-TUESDAY...

ALL THE MODELS CONTINUE TO SHOW A STRENGTHENING RIDGE ACROSS THE
EASTERN CONUS EARLY NEXT WEEK. UNDER THESE CONDITIONS WE SHOULD
REMAIN DRY MONDAY AND TUESDAY...WITH A WARM UP INTO THE LOW TO MID
80S. MODELS DO INDICATE A GLANCING SHOT OF PRECIP MONDAY NIGHT INTO
TUESDAY...BUT WILL HOLD OFF ON INTRODUCING SHOWERS OR THUNDERSTORMS
AT THIS TIME AS MODEL UNCERTAINTY IS TOO GREAT.

&&

.AVIATION (18Z TAF ISSUANCE)...

UPPER LEVEL AND SURFACE TROUGH CONTINUES TO PULL AWAY FROM THE TAF
SITES.  CONTINUED MOIST FLOW WITHIN THE COLD THERMAL TROUGH ON THE
BACK SIDE OF THE DEPARTING SYSTEM WILL CONTINUE TO PROVIDE BKN CIGS
AT KSDF AND KLEX THIS AFTERNOON.  MVFR CIGS ARE EXPECTED AT KLEX FOR
THE NEXT FEW HOURS BUT CIGS SHOULD START TO IMPROVE AND GO TO VFR BY
04/21Z.  AS THE SYSTEM CONTINUES TO PULL OFF TO THE EAST...CLEARING
SKIES ARE EXPECTED TO MOVE IN FROM THE WEST AND SKIES ARE EXPECTED
TO BE MOST CLEAR OVERNIGHT.  SFC WINDS THIS AFTERNOON WILL BE OUT OF
THE NORTHWEST AT 8-10KTS BUT WILL DROP TO LIGHT AND VARIABLE AFTER
05/01Z.
