AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
258 PM EDT SUN MAR 8 2009

.MESOSCALE UPDATE...

TORNADO WATCH NUMBER 50 HAS BEEN ISSUED AND IS IN EFFECT UNTIL 800
PM EDT FOR THE WESTERN HALF OF OUR SERVICE AREA.  NEW AFTERNOON
FORECAST AND DIGITAL PRODUCTS ARE COMING SHORTLY.

.SHORT TERM (TONIGHT AND MONDAY)...

...SEVERE WEATHER EPISODE LIKELY LATER THIS AFTERNOON AND THIS
EVENING...

PRIMARY FOCUS OF THE SHORT TERM WILL BE IN THE EARLY PART OF THE
FCST PD WITH POSSIBLE SEVERE WEATHER EPISODE LATER THIS AFTERNOON
AND EVENING.  RECENT SAT AND OBS SHOWING SOME THINNING OUT OF THE
CLOUD COVER OVER WESTERN KY.  PIREP REPORTS FROM AIRCRAFT IN THE
AREA REPORT A THICK CLOUD DECK THAT HAS BEEN AVERAGING AROUND 7-8KFT
THICK.  WHERE THE CLOUDS HAVE THINNED IN FAR SW KY AND SE
MO...LIFTED INDICES HAVE DECREASED FROM -1 TO -6 DEG C IN THE LAST
HOUR.  SLOW DESTABILIZATION HAS BEEN TAKING PLACE ACROSS OUR WESTERN
SECTIONS OF THE FA OVER THE LAST FEW HOURS.  DESTABILIZATION IS
LIKELY TO CONTINUE AT SLOW RATE UNTIL WE GET SOME THINNING OF THE
CLOUD COVER.  GIVEN THE STRONG ASCENT MOVING IN ALOFT AND STRONG
WIND FIELDS...ONLY A SMALL AMOUNT OF HEATING IS NEEDED TO GET THE
ATMOSPHERE PRIMED UP.  DEEP LAYER SHEAR IS STILL VERY IMPRESSIVE AND
GIVEN THE LONG LOW-LEVEL HODOGRAPHS...ISOLATED TORNADOES ARE QUITE
POSSIBLE.  IN FACT...IN THE LAST HOUR...STORMS HAVE REALLY INCREASED
IN INTENSITY ACROSS FAR SE MO AND FAR SW KY.

BASED ON CURRENT STORM MOVEMENT AND TRENDS...ACTIVITY SHOULD MOVE
INTO OUR FAR NW SECTIONS IN THE NEXT HOUR.  IF THE ACTIVITY HOLDS
TOGETHER AND MAINTAINS ITS CURRENT SPEED...ACTIVITY SHOULD REACH THE
I-65 CORRIDOR INCLUDING THE BOWLING GREEN AND LOUISVILLE AREAS BY
21-22Z (4-6 PM EDT)...AND IN THE LEXINGTON AREA AROUND 23 TO 01Z
(7-9 PM EDT).  A TOR WATCH IS IN EFFECT JUST WEST OF OUR AREA.
LATEST SWOMCD FROM SPC SUGGESTS A NEW WATCH WILL BE REQUIRED
SHORTLY.

WITH ALL THAT SAID...PREVIOUSLY UPDATED FORECAST REMAINS IN GOOD
SHAPE THIS EVENING. WILL ALLOW POPS TO RAMP UP TO CATEGORICAL THIS
EVENING AND THEN DROP QUICKLY AFTER FRONTAL PASSAGE.  PRECIPITATION
SHOULD BE OUT OF THE REGION BY MIDNIGHT TONIGHT WITH CLEARING SKIES
BUILDING INTO THE REGION.  MADE SOME SLIGHT ADJUSTMENTS FOR TEMPS
OVERNIGHT GIVEN THE NEW MODEL DATA THAT HAS COME IN.

FOR MONDAY...FRONTAL BOUNDARY WILL SAG SOUTH OF THE STATE AND THEN
RETREAT BACK NORTHWARD LATE IN THE DAY.  A MOSTLY DRY DAY IS
EXPECTED WITH PRECIPITATION LIKELY HOLDING OFF UNTIL THE THIRD
PERIOD (MONDAY NIGHT).  HIGH TEMPS WILL RANGE FROM THE UPPER 50S IN
THE NORTH TO THE LOW TO MID 60S ACROSS THE FAR SOUTH.

UPDATED FORECASTS AND MESOSCALE UPDATES WILL FOLLOW THROUGH THE
AFTERNOON AND EVENING AS THE CONVECTIVE EVENT PROGRESSES.

.LONG TERM (MONDAY NIGHT THROUGH SUNDAY)...

MON NIGHT THRU WED NIGHT...

POTENTIAL SEVERE EVENT IN THE NEAR TERM.

NORTH OF OUR FA BY 12Z TUE...WITH WIDESPREAD RAINS ALONG/AHEAD OF
BNDRY FROM SOUTHERN INDIANA...NORTHWARD. THAT PUTS OUR REGION IN THE
WARM SECTOR TUE AND EARLY TUE NIGHT TIL COLD FROPA WED MRNG.

BEST RAIN CHCS APPEAR TO BE PRE WARM FRONTAL MON NIGHT AND PRE COLD
FRONTAL TUE NIGHT. WILL CONTINUE CURRENT LIKELY POPS FOR THOSE
PERIODS. SHOWER CHCS SHOULD BE CONFINED MAINLY TO OUR ERN/SRN
COUNTIES WED WITH THE FRONT OVER THOSE AREAS AT THE START OF THE
DAY. ALL NEW GUIDANCE HAS PUSHED THE FRONT FARTHER SWD INTO THE SRN
GULF STATES WED NIGHT...RESULTING IN THE OVERRUNNING PATTERN
POSSIBLY BRINGING SOME RAIN OR SNOW TO OUR FA WED NIGHT...NOW OVER
THE TN VLY AND SWD. WILL REMOVE POPS FOR THAT PERIOD.

THU THRU SUN...

WILL MAKE SUBTLE CHANGES FOR THIS PERIOD. TEMPS SHUD BE NEAR MID MAR
NORMS WITH THE MILDEST DAY ON SUN.

WE START OFF IN A SPLIT FLOW PATTERN WITH THE LOWER OH VLY STILL IN
THE SRN STREAM IN FAST CONFLUENT FLO...THEN TRANSITION TO THE NRN
STREAM FRI NIGHT THRU SUN. HIGH PRES OVERSPREADS THE NRN PARTS OF
OUR REGION THU AND IS CENTERED OVER THE LOWER OH VLY BY SUN. THIS
