AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
240 AM EST MON JUN 11 2001

PROBLEM OF DAY WHETHER MIGHTY MCC NOW OVER MN WILL BRUSH CWA LATE
TONIGHT OR TUESDAY.

MOST MODEL FIELDS AGREE FOR NEXT SEVERAL DAYS...BUT ETA BRINGS A LOT
MORE MOISTURE FROM THE REMNANTS OF THE MCC BY LATE TONIGHT. THIS
REFLECTED IN THE FWC BUT NOT THE MAV POPS.

DO NOT TRUST AVN A LOT THIS TIME AROUND. LATEST PROFILERS SHOW WE
ARE STILL ON ERN SIDE OF HIGH ALOFT...AND ALL MODELS HAVE THICKNESS
PATTERNS THAT COULD EVENTUALLY TURN MCC VERY HARD TO SOUTH. INCRSG
HAZE OVER CWA SUGGESTS WE ARE STARTING TO CAP WHICH MAY HELP PROTECT
WRN COUNTIES...BUT CANT DENY CHC POPS FROM FWC LOOK OK FOR ERN
COUNTIES.

ONCE WE GET PAST THE MCC...ALL MODELS  HAVE AREA HAZY...HOT...AND
HUMID UNTIL LATE IN WEEK. ALSO PROBABLY DRY AS CAP DEVELOPS ALOFT AS
SUBSIDENCE UNDER HIGH CONTINUES. GUIDANCE HAS BEEN A LITTLE SPEEDY
BRINING UP TEMPS OVER LAST FEW DAYS. WITH VERY HUMID CONDITIONS
CONTINUING TEMPS NOT LIKELY TO REALLY SOAR. WILL SCALE BACK GUIDANCE
TEMPS ON HIGHS. MINS LOOK OK BASED ON HISTORY OF THIS AIRMASS.

.IND...NONE.
