Hail and Damaging Wind in Indiana, May 24, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
210 PM CDT MON MAY 24 2004

LATEST SURFACE ANALYSIS INDICATES NEARLY STATIONARY FRONT PERCHED
OVER NORTHERN SECTIONS OF THE FORECAST AREA. SOUTHWEST FLOW ALOFT
REMAINS INTACT OVER THE SOUTHWEST 1/3 OF THE REGION WITH SFC DEW
POINTS FROM 70 TO AS HIGH AS 74 AT POF.

WIDELY SCATTERED THUNDERSTORMS JUST AHEAD OF FRONT OVER SOUTHWEST KY
EARLY THIS AFTERNOON LOOK TO BE IN ASSOCIATION WITH A DISTURBANCE
ALOFT DEPICTED WELL BY THE 12Z ETA MODEL RUN. THIS DISTURBANCE WILL
SHIFT EAST OUT OF THE REGION BY MID AFTERNOON...BUT ANOTHER WAVE OF
ENERGY DEPICTED BY THE ETA WILL MOVE IN BY LATE AFTERNOON. THIS
COULD TOUCH OFF SCATTERED THUNDERSTORMS AS WELL AS IT MOVES INTO THE
MOIST/UNSTABLE AIR OVER THE OHIO RIVER VALLEY. WILL NEED TO MONITOR
ANY STORM THAT DOES DEVELOP FOR THE POSSIBILITY OF HAIL AND DAMAGING
WIND GUSTS.

12Z MON MODEL RUNS IN AGREEMENT WITH HOLDING FRONT NEARLY
STATIONARY FOR THE NEXT 24 TO 36 HOURS AS RIPPLES OF ENERGY MOVE
QUICKLY EAST ACROSS THE MID MS VALLEY IN THE NEARLY ZONAL 500 MB
FLOW. BEST CHANCE OF THUNDERSTORMS LATE TONIGHT AND TUE SHOULD BE
OVER OUR NORTHERN COUNTIES IN IL/IN...CLOSER TO AND JUST NORTH OF
THE SFC FRONT. ACTIVITY TONIGHT WILL LIKELY BE DEPENDENT ON HOW LONG
AN AREA OF SEVERE THUNDERSTORMS DEVELOPING OVER THE CENTRAL
PLAIN/MIDWEST THIS AFTERNOON CAN MAINTAIN STRENGTH AFTER SUNDOWN. IF
THEY DO MANAGE TO MAKE IT INTO OUR AREA...IT WOULD PROBABLY BE WELL
AFTER MIDNIGHT.

ETA THERMODYNAMIC PROFILES SUGGEST DECENT CAPPING ON TUE...ESPECIALLY
SOUTH OF THE FRONT IN SE MO AND WRN KY...SO WILL DROP RAIN CHCS TO
THE SLIGHT CATEGORY IN THOSE AREA FOR TUE. HOWEVER...WILL MAINTAIN
CHC POPS IN MUCH OF SRN IL /SRN IN.

THE FRONT IS FORECAST TO SAG JUST SOUTH OF THE FORECAST AREA BY 18Z
WEDNESDAY. HOWEVER...A RATHER POTENT H50 SHORT WAVE IS FORECAST BY
BOTH ETA AND GFS TO MOVE EAST AND SLING PRECIP BACK TO THE NORTH OF
THE FRONT DURING THE DAY. WITH MODELS IN AGREEMENT IN STRENGTH AND
TIMING...THINK WED MAY END UP BEING THE WETTEST DAY OVERALL AS FAR
AS PRECIP AREAL COVERAGE. WILL BUMP POPS UP TO LIKELY ACCORDINGLY.

WILL CONTINUE WITH DAILY CHC OF PRECIP IN THE EXTENDED AS ATMOSPHERE
REMAINS UNCAPPED AT LEAST BY AFTN EACH DAY WITH 700 MB TEMPS COOLER
THAN 10C. WILL MAINTAIN DAILY MENTION OF POPS AS NUMEROUS H50
VORTICES MAXES ARE PROGGED TO PASS OVER THE REGION THROUGH THIS
FORECAST PERIOD AS THE WEST SOUTHWEST FLOW ALOFT PERSISTS.

MAIN DISCREPANCY IN MODEL TEMP FORECAST COMES ON WED. WILL SHADE
TOWARD THE COOLER AVN MOS (MAV) NUMBERS FOR NOW SINCE WE SHOULD BE
ON THE COOL SIDE OF THE SURFACE FRONT WITH QUITE EXTENSIVE PRECIP
COVERAGE EXPECTED. WILL HOLD HIGHS IN THE MID/UPPER 70S MOST AREAS.
