Hail and Damaging Winds in Kentucky, July 15, 2007

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
712 PM EDT SUN JUL 15 2007

.AVIATION...
THE TAF SITE TO BE MOST THREATENED BY PRECIPITATION IS BOWLING
GREEN. ISOLATED SHOWERS WERE SLIDING SOUTHEAST INTO SOUTHERN
KENTUCKY AT 23Z...SO WILL HAVE VCSH IN THE BWG TAF FOR THE FIRST FEW
HOURS OF THE FORECAST. LITTLE IF ANY THUNDER IS EXPECTED SO I
OMITTED SPECIFIC MENTION OF THUNDER IN THE TAF BUT DID INCLUDE A CB
CLOUD GROUP TO GIVE THE IDEA THAT A THUNDERSTORM OR TWO COULD BE
AROUND THE AREA. SDF AND LEX WILL BE THUNDER AND RAIN FREE.

BRIEF HEAVY RAIN FELL AT SDF THIS EVENING AND SOME LIGHT RAIN
OCCURRED AT LEXINGTON AS WELL. WITH LITTLE IF ANY WIND TONIGHT PLUS
CLEARING SKIES AND LOW DEW POINT DEPRESSIONS DECIDED TO THROW IN A
FEW HOURS OF MVFR FOG AROUND SUNRISE AT THOSE LOCATIONS. KEPT BWG
FOG-FREE BUT WILL NEED TO MONITOR TRENDS THERE FOR POSSIBLE
INCLUSION WITH LATER FORECASTS.

THE COLD FRONT THAT SPARKED TODAY/S SHOWERS AND THUNDERSTORMS WILL
WASH OUT EARLY TOMORROW MORNING LEAVING DRY VFR CONDITIONS IN ITS
WAKE FOR THE DAY ON MONDAY.

13

.UPDATE #2...
PREVIOUSLY MENTIONED STORMS HAVE MOVED OUT OF THE LOUISVILLE AREA OF
RESPONSIBILITY. NEW STORMS TRYING TO GO UP FROM CLARK TO GARRARD
COUNTIES IN KENTUCKY...WILL KEEP AN EYE ON THOSE.

HAVE UPDATED THE ZONES AND GRIDS TO REMOVE THUNDER FROM AREAS NORTH
OF INTERSTATE 64...BUT KEPT A CHANCE OF AN ISOLATED SHOWER THERE.
SOUTH OF INTERSTATE 64 NO REAL CHANGES WITH ISOLATED SHOWERS AND
STORMS STILL EXPECTED. INCREASED CLOUD COVER NUMBERS SIGNIFICANTLY
AS THE STORMS PRODUCE OVERCAST SKIES.

13

.UPDATE...
WILL UPDATE ZONES TO REMOVE AFTERNOON WORDING SOON...AND WILL UPDATE
GRIDS ACCORDINGLY. HOWEVER FIRST I WILL BE PAYING ATTENTION TO A
LINE OF STRONG STORMS IN BOURBON AND NICHOLAS COUNTIES AT 22Z THAT
IS LIKELY PRODUCING PEA SIZED HAIL ALONG WITH BRIEF TORRENTIAL RAIN
AND FREQUENT LIGHTNING. THE STORMS ARE MOVING TO THE EAST AND
SOUTHEAST. ONCE THESE STORMS LEAVE MY AREA OF RESPONSIBILITY OR
WEAKEN I WILL UPDATE THE ROUTINE FORECAST PRODUCTS.

.SHORT TERM (TONIGHT THROUGH MONDAY AFTERNOON)...

MAIN FEATURE IN THE SHORT TERM IS THE COLD FRONT PUSHING ACROSS THE
OHIO VALLEY TONIGHT. THE UPPER LEVEL PATTERN HAS CHANGED LITTLE
THE LAST FEW DAYS...WITH THE TROUGH REMAINING ACROSS THE EASTERN
STATES. DEWPOINTS MIXED OUT SOME THIS AFTERNOON...DROPPING INTO
THE MIDDLE AND LOWER 60S AT BWG...SDF AND LEX. ISOLD TO SCTD
CONVECTION HAS DEVELOPED AHEAD OF THE FRONT OVER SOUTHERN
INDIANA...AND IS PUSHING INTO NORTHERN KY LATE THIS AFTERNOON.
CURRENT MSAS AND LAPS DATA SHOWS THE REGION OF SOUTHERN INDIANA
WHERE THE CONVECTION IS DEVELOPING HAS LIS NEAR -7 AND CAPES MORE
THAN 2500 J/KG...THIS INSTABILITY DROPS OFF AS YOU MOVE EAST AND
SOUTH WITH ONLY AROUND -3 OR -4 LIS AND CAPES NEAR 1000-1500 J/KG
FROM LEXINGTON SOUTH TOWARDS ALBANY AND BURKESVILLE.

COLD FRONT WILL CONTINUE IS PAINFULLY SLOW PROGRESS TO THE SOUTH
TONIGHT...WITH SOME LINGERING ISOLATED ACTIVITY POSSIBLE ALONG
AND AHEAD OF THE FRONT THROUGH THE NIGHT AS IT PUSHES ACROSS
CENTRAL KY. HAVE TRENDED THE GRIDS TO SHOW A SMALLER BAND OF POPS
AND CLOUDS MOVING ACROSS THE REGION AS TO MATCH CURRENT TRENDS OF
EACH. TEMPERATURES WILL BE FAIRLY SEASONABLE FOR MID JULY
OVERNIGHT...WITH SLIGHTLY LOWER DEWPOINTS MOVING INTO THE REGION
FROM THE NORTH.

WITH THE WEAKENING BOUNDARY NEARLY STATIONARY OVER THE
AREA...ALONG WITH A WEAK SHRTWV DROPPING ALONG THE NORTHWEST FLOW
WILL KEEP THE LOW POPS IN THROUGH THE DAY MONDAY...BEST TIME WILL
BE DURING THE AFTERNOON FOR ISOLATED SHOWERS AND THUNDERSTORMS AS
HEATING WILL CREATE PLENTY OF INSTABILITY. DEWPOINTS SHOULD BE
SLIGHTLY LOWER THAN TODAY...WITH AFTERNOON TEMPERATURES JUST A
DEGREE OR TWO COOLER THAN TODAYS MAXES.

.LONG TERM (MON NGT THRU SUN)...

MON NGT THRU WED NGT...

MAINLY JUST A DIURNAL CHC OF SHWRS/TSTMS DURG THIS PD AS UPR RIDGE
EXPANDS NEWD FROM THE SRN U.S...RESULTING IN CONTD INCREASING TEMP
TREND.

GULF MOISTURE ROUNDING HI PRES OVER THE SERN U.S...FCST TO NUDGE NWD
THRU THE PD WHILE A FRONT MEANDERS ACRS THE UPR OH VLY. OUR FA
REMAINS IN A RELATIVELY DRY VOID BETWEEN HIGHER MOISTURE POOLED NEAR
BNDRY WELL TO OUR NORTH AND RETURN FLO MOISTURE CREEPING UP FROM THE
SOUTH. HOWEVER...WITH A SLY COMPONENT OF WIND/INCREASINGLY MOIST...
UNSTABLE AMS SHUD LEAD TO ISOLATED DIURNAL CONVECTION TYPICAL OF

THU THRU SUN...

A TYPICAL MID SUMMER HOT/MUGGY PATTERN EXPECTED FIRST HALF OF THIS
PD WITH MAX/MIN TEMPS AROUND 90/70 AND DEWPOINTS NEAR 70...A BIT
COOLER FOR THE WEEKEND AS CDFNT DROPS SWD THRU OUR FA LATE FRI/FRI
NGT.

THIS FCST DERIVED MAINLY FROM THE OPS ECMWF WITH AN ASSIST FROM THE
GFS ENSEMBLE MEAN. OUR FA SANDWICHED BETWEEN UPR LVL RIDGING TO OUR
SOUTH AND WEST AND LNWV TROF ACRS THE ERN GREAT LAKES INTO NEW
ENGLAND. A QUASI STATIONARY FRONT PROGGED TO EXTEND ACRS CENTRAL
PARTS OF IN/OH AT THE START OF THE PD...FCST TO MAKE A SWD PUSH LATE
THU INTO FRI AS A SHRTWV TROF DROPS FROM THE UPR GREAT LAKES INTO
THE OH VLY FRI AND NEW ENGLAND/MID ATL STATES SAT. PROGGED POSITION
OF FRONT...NEAR THE KY/TN BORDER BY SAT MORNING. TIL THEN 30/40 POPS
