AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
220 PM EST SAT AUG 5 2000

PROB OF THE DAY IS SVR POTENTIAL TNGT WITH HEAVY RAIN TNGT ANOTHER
CONCERN.

LATEST SFC ANLYS HAD A WARM FNT WELL NE OF THE FA ACRS WRN PA-LK
ERIE-CNTRL LWR MI. MEANWHILE...A CD FNT WAS FM WRN WI TO CNTRL IA TO
NRN KS. THUS...THE FA IS NOW IN THE WARM SECTOR WITH WIDESPREAD LOWER
TO MIDDLE 70S SFC DEW PTS...LI'S TO -7 AND CAPES TO 3500 J/KG IN
AREAS THAT RECEIVED SS. H20 VAPOR IMAGERY WAS INDICATING A S/W TROF
MOVING INTO WRN IA WITH 06 HR MODEL PROGS IN GOOD AGREEMENT. VSBL SAT
LOOP WAS BEGINNING TO SHOW SOME BREAKS ACRS THE FA WITH EVEN MORE
BREAKS ACRS IL. FINALLY...KIND-88D WAS JUST SHOWING A FEW LGT SHOWERS
SCATTERED ABOUT THE FA.

MODELS ARE FAIRLY CLOSE AND REASONABLE EARLY ON WITH MOST OF THE SFC
AND UPR AIR FEATURES AS THEY SWING THE IA S/W ACRS THE FA TNGT WITH A
90 KT SPEED MAX AT 250 MB MOVING ACRS THE LWR GT LKS TNGT PROVIDING
VERY DECENT UPR DVRG FOR THIS TIME OF YEAR. IN ADDITION...ANOTHER LOW
LVL JET OF 35 TO 40 KTS IS PROGGED TO SET UP TNGT ACRS THE SRN FA.
ALSO...THE CD FNT WL REACH XTRM NWRN PARTS OF THE FA BY MON MRNG
BEFORE LIFTING BACK TO THE N AS A WARM FNT MON AFT AND INTO CNTRL MI
ON TUE. THE SHEAR TNGT IS UNI-DIRECTIONAL BUT STG FOR THIS TIME OF
YEAR WHICH POINTS TO A CLASSIC BOW-ECHO TYPE SETUP WITH DAMAGING
WINDS THE MAIN THREAT. SPC HAS MOD RISK ACRS ALL OF THE FA AS A
RESULT. AREA OF 2 IN PRECIP WATER ACRS THE FA TNGT AND COMBINED WITH
UPR LVL DVRG SHOULD ALLOW RN TO BE HEAVY AT TIMES TNGT ESP THIS EVE
WHEN DVRG VALUES ARE HIGHEST. HOWEVER...FFG 1 HR VALUES ARE STILL
AROUND 1.5 IN AND 3 HR VALUES 2-2.5 IN AND WITH FAST MOVEMENT OF THE
EXPECTED SQUALL-LINE...WL NOT ISSUE FFA ATTM. WL HAVE TO TWEAK UP
POPS THOUGH PROBABLY TO THE LIKELY CAT. WITH THE WARM FNT MOVING N ON
MON AND NO REAL LIFTING MECHANISMS TO KEY IN ON...WL DROP POPS BACK
TO THE LOW CHC CAT. ANY NON-RESOLVED WK S/W IN THE ZONAL FLOW COULD
POP UP A TRW OR TWO...HOWEVER. MODEL TIME SECS SHOW NICE MID LVL
DRYING ON MON AND CU DEVELOPMENT PROGS NOT INDICATING MUCH CU...SO
SHOULD SEE A GOOD DEGREE OF SS AND MIXING ALLOWING FOR VERY WARM
TEMPS. ETA/AVN BRING A S/W AND NICE UVM FIELD ACRS MON NGT AND TUE
WHICH SHOULD ALLOW FOR ADDITIONAL ROUNDS OF TRW'S.

WARMER FWC NUMBERS LOOK GOOD AT NGT AS CURRENT DEW PTS GREATER THAN
FAN LOWS AND AIRMASS WL REMAIN ESSENTIALLY UNCHANGED. WARMER FWC
HIGHS ALSO LOOK GOOD AS H8 THERMAL RIDGE NOSES INTO CNTRL IN THROUGH
THE PD WITH TEMPS AROUND 20 DEGREES CELSIUS.

.IND...NONE.
