Severe Thunderstorm Warning 6, NWS Louisville, KY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
330 AM EST WED MAR 19 2003

CONCERNS FOCUS ON SEVERE THREAT THIS MORNING INTO THE AFTN.
WIDESPREAD COVERAGE OF SHOWERS AND A FEW STRONG TSTM SEGMENTS ON
MEMPHIS AND NASHVILLE RADARS ATTM. THIS ACTIVITY WILL PUSH INTO CTRL
KY THIS MORNING AND FURTHER NORTHEAST INTO AFTN. ALTHOUGH SOME
WEAKENING EXPECTED BEFORE DAYBREAK...ACTIVITY SHOULD RE-INTENSIFY
LATER THIS MORNING AS LOW/MID LEVEL LAPSE RATES STEEPEN AND
FAVORABLE UPPER LEVEL DIVERGENCE MOVES INTO AREA. EVEN SO SEVERE
THREAT MARGINAL GIVEN A LACK OF INSTABILITY.

ETA AND GFS IN GOOD OVERALL AGREEMENT. GFS BRINGS IN SOME DRYING TO
THE SOUTHWEST PORTION OF FA THIS AFTN AND SHIFTS HEAVIER PRECIP INTO
CTRL INDIANA BY THAT TIMEFRAME. MEANWHILE ETA & UKMET ARE A LITTLE
SLOWER. WILL LEAN MORE WITH THE GFS IN TERMS OF TAPERING OFF THE
PRECIP THIS AFTN ESPECIALLY IN THE SOUTHWEST AND ALLOW FOR SOME
PARTIAL CLEARING THERE. ALTHOUGH MAIN AXIS OF CONVECTION SHOULD PUSH
NORTH OF KY THIS AFTERNOON AS LOW LEVEL BOUNDARY/WARM FRONT APPROACH
AND DYNAMICAL FORCING WEAKENS...GIVEN ANY SUNSHINE THIS AFTERNOON WE
COULD HAVE ISOLATED TO SCATTERED CONVECTION FIRE UP WITH INCREASING
MODEST  INSTABILITY. AT ANY RATE WILL MENTION MAINLY THIS MORNING
WORDING IN THE SOUTH AND BUMP UP POPS TO CATEGORICAL...TIMING MAINLY
THROUGH EARLY OR MID AFTERNOON OVER NORTHERN FA.

FOR TONIGHT...WILL KEEP A LOW CHANCE POP IN FOR THE EVENING
OTHERWISE PARTLY CLOUDY. ALTHOUGH AIRMASS WILL STILL BE WARM...DRY
SLOT OF SYNOPTIC SYSTEM TAKES OVER BY EVENING. WE SHOULD HAVE SOME
MODEST RADIATIONAL COOLING GIVEN THE SKY COVER. CURRENT FCST LOWER
50S LOOKS FINE. SUBSTANTIAL WARMING INTO MID OR POSSIBLY UPPER 70S
ON THURSDAY GIVEN SUNSHINE AND AIRMASS SHOULD BECOME QUITE UNSTABLE.
IN ADDITION STRONG PVA MOVES INTO THE LOWER OHIO VALLEY IN ADVANCE
OF ANOTHER SHORTWAVE. WILL CONTINUE 50 POPS AND EXPECT MOST ACTIVITY
TO BE IN THE AFTERNOON.

FOR THU NIGHT AND FRI WILL GO WITH CHANCE SHOWERS AS UPPER TROUGH
FINALLY MOVES THROUGH WITHOUT A LOT OF ADDITIONAL FORCING AVAILABLE
TO WORK WITH. LOWER THUNDERSTORM PROBABILITY DURING THAT TIMEFRAME.
SEASONAL TEMPS THIS WEEKEND IN UPPER 50S TO LOWER 60S AND GENERALLY
DRY CONDITIONS EXPECTED.

.SDF...NONE.
