AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
624 PM EST SAT MAR 7 2009

.AVIATION...DISCUSSION FOR 0Z TAFS.
FNT CURRENTLY LOCATED AROUND KLAF WILL SINK SOUTH A BIT AS WAVE
MOVES ALONG IT TO STALL OUT SOMEWHERE BETWEEN KLAF AND KIND TONIGHT.
THIS WILL CAUSE CONDS TO DROP SIGNIFICANTLY WITH THE WORST
CONDITIONS SHOWING UP AT KLAF FOR THE LONGEST TIME. EXPECTING TSRA
CURRENTLY JUST WEST OF KLAF TO FINALLY SHOW UP THERE BY AROUND 1Z
AND COULD SEE CONVECTIVE CELLS MOVING THRU THERE UNTIL 3Z OR SO. THE
SOUTHERN END OF THE RAIN AREA CURRENTLY OVR IL IS NOT PRODUCING ANY
LIGHTNING SO AT THIS TIME WILL INCLUDE A VCTS FOR THE OTHER SITES
BUT WILL LEAVE TSRA OUT. CIGS AT KLAF WILL DROP AS FNT HEADS FURTHER
SOUTH AND SHUD BE LIFR BY 12Z. EXPECTING IFR AT KHUF AND KIND AROUND
THE SAME TIME AS FNT SHUD BE HOVERING NR. HEAVIEST RAIN LOOKS LIKE
IT WILL BE CENTERED AROUND 12Z BASED ON BEST LIFT. EXPECTING TO SEE
SOME THUNDERSTORMS TOMORROW BEFORE/CONCURRENT WITH COLD FROPA BUT
TOO LARGE UNCERTAINTY ON TIMING TO INCLUDE AT THIS ISSUANCE SO WL
CARRY A CB UNTIL FROPA.

&&

.PREV DISCUSSION...
THE MAIN CHALLENGE TO THE FCST CONTINUES TO BE TIMING...CVRG OF
TRWS ACRS THE FA THROUGH THE WEEKEND ALONG WITH TEMPS. HEAVY RAIN A
CONCERN MAINLY ACRS OUR FAR NRN COUNTIES TNGT...WHILE SEVERE STORMS
WL ALSO BE A CONCERN ESPECIALLY SUNDAY AFTERNOON AND EVE.

EARLY AFTERNOON SFC ANALYSIS HAD A QUASI-STNRY FNT FM JUST N OF A
FWA-SPI LINE WITH THE MAIN ASSOCIATED SFC LOW NEAR THE OK PANHANDLE
AND A DRY LINE EXTENDING FM THE LOW S ACRS WRN OK AND WRN TX.
MEANWHILE...HIGH PRES HELD SWAY ACRS THE SERN CONUS. UA PATTERN
FEATURED A PERSISTANT SERN RIDGE AND A TROF ACRS WRN CO WITH FAST SW
FLOW ACRS THE OH AND TN VLYS AND GT LKS.

THE 12Z NAM HAS NOW COME INTO BETTER AGREEMENT WITH THE GFS ON THE
SPEED AND STRENGTH OF THE SW SFC LOW THAT WL BE KICKED NE BY THE WRN
CO TROF AND MOVE ACRS THE LWR GT LKS LATE SUNDAY. THE KEY TO TNGTS
FCST WL BE THE LOCATION OF THE QUASI-STNRY FNT AS THE BULK OF THE
TRW ACIVITY HAS BEEN ELEVATED ALONG AND TO THE N OF THIS FNT. THE
NAM HAS THE FNT OSCILATING S ACRS OUR NRN FA OVERNGT TNGT AND THEN
LIFTING BACK N OF OUR CWA SUNDAY AFTERNOON IN RESPONSE TO THE NEWD
MOVING SFC LOW. ASSOCIATED CD FNT THEN EXPECTED TO MOVE W-E ACRS THE
FA LATE TOMORROW AFTERNOON THROUGH TOMORROW EVE WHICH COULD BRING
SOME SVR STORMS TO CNTRL INDIANA.

WL HIT OUR NRN TWO TIERS OF COUNTIES WITH CAT POPS TNGT BEING CLOSE
TO THE QUASI-STNRY FNT AND TAPER TO ONLY CHC POPS FOR OUR SRN ZONES
BASED ON PERSISTANCE. WL KEEP HEAVY RAIN MENTION IN OUR NRN TIER
TNGT. FLOOD WATCH IS MARGINAL AFTER SEEING THIS MRNGS FFG
VALUES...SO WL KEEP IT OUT. SHOULD BE A LULL IN THE PRECIP AFT 12Z
SUN AS THE FNT IS EXPECTED TO LIFT N. HOWEVER...THAT SHOULD QUICKLY
CHG DURING THE AFTERNOON ESP IF THERE ARE ANY BREAKS IN THE CLOUD
COVER. SLGT RISK CURRENTLY GOING FOR DAY2 AND COULD EASILY BE
REALIZED WITH ANY SFC BASED INSTABILITY AS THERE WL BE STG MAINLY
DIRECTIONAL SHEAR WITH LOW LVL JET AROUND 55 KTS AND W-E 250 MB 130
KT JET ACRS SCNTRL INDIANA. SO...WL GO WITH OCCASIONAL POPS ALL
ZONES ON SUNDAY WITH CD FNT MARCHING THROUGH. FINALLY...BASED ON
FASTER NAM NOW IN LINE WITH THE PERSISTANT GFS...TOOK POPS OUT SUN
NGT. NEXT CHC OF TRWS WL BE MON NGT INTO TUE NGT AHEAD OF ANOTHER
LOW PRES SYS.

EXTENDED LOOKS DRY AND COOLER AS COOL CANDIAN HIGH PRES BUILDS IN.

MOS TEMPS ARE PRETTY CLOSE TNGT THROUGH SUN NGT AND APPEAR
REASONABLE...BUT WL MAKE A TWEEK OR TWO HERE AND THERE BASED ON
EXPECTED FRONTAL POSITION MAINLY.
