AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
302 PM EDT THU JUN 9 2011

.SHORT TERM (TONIGHT AND FRIDAY)...

ISOLATED TO SCATTERED CONVECTION HAS FIRED OFF SO FAR THIS
AFTERNOON...WITH EMPHASIS NEAR WHERE OLD OUTFLOW BOUNDARY FROM
OVERNIGHT STORMS TO OUR NORTH SAT. SEEING SOME NEW ACTIVITY FIRING
IN THE NORTHWEST CWA AS WELL AND EXPECT SCATTERED STORMS ACROSS THE
EASTERN TWO-THIRDS OF THE AREA THE REST OF THE AFTERNOON. WITH
TODAY/S STORMS HAVE A FEW THAT HAVE REACHED HIGH ENOUGH AND ARE COLD
ENOUGH TO SUPPORT NICKEL-SIZED HAIL...PERHAPS A FEW QUARTER-SIZE BUT
THERE HAVE NOT BEEN REPORTS JUST YET. ON THE WIND SIDE HAVE NOT SEEN
MORE THAN 35 MPH FROM THE MESONET SITES...BUT HAVE HAD A TREE OR TWO
DOWN...SO PROBABLY GETTING UP TO 50 IS ISOLATED SPOTS.

STORMS SHOULD QUIET DOWN WITH THE SETTING SUN TONIGHT. EXPECT TO SEE
MORE FIRE OFF FRIDAY WITH FRONTAL BOUNDARY IN THE VICINITY. IT MAY
LIFT NORTH AGAIN DURING THE DAY...BUT EXPECT AT LEAST ADDITIONAL
DEVELOPMENT THROUGH THE DAY. HAVE SCATTERED COVERAGE OVER THE NORTH
HALF OF THE CWA AND ISOLATED TO THE SOUTH. COOLER HIGH TEMPERATURES
SHOULD KEEP CAPES DOWN FROM TODAY...SO NOT AS WORRIED ABOUT SEVERE
FOR NOW. GOING FOR READINGS AROUND 90 DEGREES AREAWIDE. LOWS TONIGHT
SHOULD BE SIMILAR TO LAST NIGHT...THOUGH PERHAPS A FEW DEGREES
COOLER AT KSDF...ESPECIALLY IF THEY CAN GET A SHOWER TO PASS THROUGH
THERE IN THE NEXT FEW HOURS.

.LONG TERM (FRIDAY NIGHT - THURSDAY)...

UPPER LEVEL RIDGING WILL BE SUPPRESSED DURING THIS PERIOD WITH ZONAL
FLOW THRU THE WEEKEND...BECOMING NWLY AT THE START OF THE WORKWEEK
AS RIDGE CENTER RETROGRADES TO THE SOUTHERN PLAINS. THIS WILL ALLOW
A COOL FRONT TO APPROACH OUR FORECAST AREA BY LATE FRIDAY NIGHT AND
MOVE THRU MUCH OF OUR REGION BY LATE SATURDAY. SCATTERED CLUSTERED
TSTMS WILL PRECEDE AND ACCOMPANY THE FRONT...WITH FROPA TIMING IN
THE AFTERNOON (NRN CWA) AND EVENING (SRN/ERN CWA) GIVEN AN
INSTABILITY BOOST WITH CONTINUED AMPLE LOW LEVEL MOISTURE.

WE SHOULD SEE A LULL IN ACTIVITY LATE SATURDAY NIGHT INTO EARLY
SUNDAY AS PROGRESSIVE FRONT CONTINUES SOUTHEAST INTO THE GULF STATES
AND UPPER OHIO VALLEY HIGH PRESSURE NOSES INTO OUR REGION.
AFTERWARD...WILL KEEP LOW CHC POPS MONDAY AND TUESDAY AS SUBTLE
UPPER LEVEL IMPULSES DROP SEWD IN AFOREMENTIONED NWLY FLOW. WILL
BUMP POPS UP A BIT BEGINNING TUE NIGHT INTO MID WEEK AS WINDS BECOME
MORE SLY/SELY AS HIGH REACHES VA/NC EARLY WED AND OFF THE MID
ATLANTIC COAST WED NIGHT AND THU. IT APPEARS THE BEST CHC OF
SHOWERS/STORMS WILL BE WEDNESDAY NIGHT INTO THU AS A WARM FRONT AND
INFLUX OF HIGHER MOISTURE/UNSTABLE AIR PRECEDES A COLD FRONT THAT
SHUD EXIT OUR REGION BY THU NIGHT.

TEMPS SHUD BE MODIFIED SOMEWHAT BY MORE CLOUDS/SCATTERED
SHOWERS/TSTMS SAT BUT MAXS SHUD STILL BE CLOSE TO 90.
AFTERWARD...ZONAL/NWLY UPPER LEVEL FLOW/MORE CLOUDS AND ISOLATED TO
SCATTERED SHOWERS/STORMS...SHUD HOLD MAX TEMPS IN THE MID/UPPER
80S.

&&

.AVIATION (18Z TAF ISSUANCE)...

SCATTERED CU FIELD DEVELOPING AT THIS TIME. HAVE VERY ISOLATED
STORMS POPPING THROUGH THIS FIELD...AND BOUNDARIES FROM THESE STORMS
WILL COMBINE WITH THE LARGER OUTFLOW BOUNDARY FROM EARLY TO DEVELOP
NEW STORMS THE REST OF THE AFTERNOON. NO ENOUGH CONFIDENCE TO PUT IN
PREVAILING TS AT THIS POINT...BUT HAVE EITHER CB GROUPS OR VCTS AT
KSDF AND KLEX. AFTER THE ONE CELL JUST SOUTH OF KBWG NOW MOVES
EAST...EXPECT THEM TO STAY DRY REST OF AFTERNOON.

WINDS WILL GO NEARLY CALM TONIGHT UNDER MOSTLY CLEAR SKIES AS
AFTERNOON CONVECTION DISSIPATES. LIKELY WILL SEE SOME MVFR VSBY'S
AFTER MIDNIGHT...WITH WORSE CONDITIONS POSSIBLE IN LOCATIONS THAT
RECEIVE GOOD RAINFALL TODAY.

EXPECT DEVELOPMENT AGAIN TOMORROW AS FRONTAL BOUNDARY NEAR REGION
COMBINES WITH JUST ENOUGH MOISTURE FOR A CU FIELD AND ADDITIONAL
AFTERNOON STORMS.
