AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
1227 PM EST SAT MAY 22 2004

.AVIATION...
AREA OF STORMS WILL MOVE THROUGH THE TERMINALS THIS AFTERNOON AS
UPPER VORT PUSHES INTO UNSTABLE ATMOSPHERE. AFTER THE STORMS PASS
WEATHER SHOULD BE FAIRLY QUIET. MESOETA HINTING AT A CHANCE OF TSRA
SUNDAY MORNING BUT WILL HOLD OFF ON THAT IN THE TAFS FOR NOW.
&&

.UPDATE...
DECIDED TO ADD A SMALL CHANCE OF STORMS TO THE SOUTH THIS AFTERNOON.
MESOETA DEPICTS HEALTHY 500MB VORT IN THERMAL TROF PASSING THROUGH
THIS AFTERNOON IN UNSTABLE ATMOSPHERE. SOUNDINGS SHOW CAP WEAKENING
THIS AFTERNOON AND 700MB TEMPS COOL OFF A FEW DEGREES. SMALL 850MB
JETLET REVS UP OVER NORTHN INDIANA THIS AFTERNOON AS WELL. POSSIBLE
OUTFLOW BOUNDARIES AND AREA OF THUNDERSTORMS EXTENDING FROM SOUTHERN
WISCONSIN TO CENTRAL MISSOURI AT 16Z MOVING STEADILY EAST ARE
ADDITIONAL FACTORS. ALSO NOTED THAT SPC MOVED THE SOUTHERN EDGE OF
THE SLIGHT RISK AREA SOUTH TO ENCOMPASS THE ENTIRE IWX CWFA.

ALSO EDGED HIGH TEMPS IN MICHIGAN UP A FEW DEGREES...79 DEGREES AT
COLDWATER ALREADY AT 16Z.
&&

.PREV DISCUSSION...
SHORT TERM...
A SERIES OF THUNDERSTORM COMPLEXES WILL MOVE ACROSS SOUTHWEST LOWER
MI AND NORTHERN INDIANA/NW OH TODAY. A DEVELOPING CLUSTER OF STORMS
WAS OVER EASTERN IA AND WAS ACCELERATING EAST SOUTHEAST TOWARD
NORTHERN INDIANA AND SW LOWER MI EARLY THIS MORNING. THIS SYSTEM
SHOULD REACH LAPORTE/BEH BETWEEN 830 AM EST AND 10 AM ACCORDING TO
STORM PROGS. AS WITH YESTERDAY...APPEARS DERECHO PATTERN INDICATED
WITH A STRONG POSSIBILITY OF DAMAGING WINDS.  AHEAD OF THIS
SYSTEM...OUTFLOW BOUNDARY HAD PUSHED SOUTH TO ABOUT A WINAMAC TO FWA
LINE AND HAD BECOME STATIONARY. ANOTHER OUTFLOW FROM STORMS OVER
LAKE MI SHOULD STRENGTHEN THIS LEADING BOUNDARY...AND PROVIDE AN
ADDITIONAL TRIGGER FOR STORMS TODAY. HAVE EXTENDED FLOOD WATCH FOR
TODAY OVER FAR SOUTHWEST LOWER MI AND ABOUT 2 TIERS DEEP IN N
INDIANA AND NW OH. ALTHOUGH STORMS SHOULD HAVE RELATIVELY FAST
MOVEMENT...EXPECT SOME TRAINING OVER AREAS THAT HAVE RECEIVED HEAVY
RAINFALL LAST COUPLE OF DAYS. NCEP MODELS HAVING HARD TIME HANDLING
LOCATION OF FRONT WITH MODIFICATION OF AIRMASS AND OUTFLOW
BOUNDARIES. LAST COUPLE OF DAYS...ETA WAS TRYING TO MOVE THE FRONT
TOO FAR NORTH...SO AM HESITANT TODAY TO BUY SAME PATTERN INDICATED
BY THE ETA...SO WENT IN THE NORTH...MI...WITH HIGHER POPS THERE. 00Z
ILX SOUNDING SHOWING FAIRLY SOLID CAP THAT WAS HOLDING CONVECTION
OVER SOUTHERN AREAS MORE IN CHECK. THEREFORE...SHOULD BE A TIGHT
GRADIENT OF STORM COVERAGE TODAY FROM NORTH TO SOUTH AS AREAS TOWARD
PORTLAND AND MONTICELLO SHOULD BE PRETTY WELL CAPPED. WILL CONTINUE
CHANCE OF STORMS TONIGHT...WITH BEST CHANCE IN THE NORTH...AWAY FROM
THE CAP.

LONG TERM...
FORECAST CHALLENGE IS CHANCE FOR SHOWERS AND THUNDERSTORMS SUNDAY
THROUGH WEDNESDAY.

ETA AND GFS IN REASONABLE AGREEMENT WITH BRINGING 500 MB SHORTWAVE
AND COLD FRONT ACROSS FORECAST AREA SUNDAY AND SUNDAY
NIGHT...SUPPORTING GOING CHANCE FOR SHOWERS AND THUNDERSTORMS.  MUCH
IF NOT ALL OF FORECAST AREA SHOULD BE DRY ON MONDAY AS SOMEWHAT
DRIER AND MORE STABLE AIRMASS WILL BE OVER REGION.  SOUTHERLY FLOW
WILL ONCE AGAIN BRING DEEPER MOISTURE INTO FORECAST AREA MONDAY
NIGHT AND A COLD FRONT WILL SWEEP ACROSS THE FORECAST AREA
TUESDAY...PROVIDING ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS.
HIGH PRESSURE BUILDING IN BEHIND FRONT SHOULD PROVIDE FOR A DRY
PERIOD FROM WEDNESDAY AFTERNOON THROUGH FRIDAY.

ETA AND GFS MOS NUMBERS ARE IN EXCELLENT AGREEMENT FOR SUNDAY AND
SUNDAY NIGHT AND WILL STAY CLOSE.  GIVEN INCREASING CLOUDINESS IN
ASSOCIATION WITH FRONTAL PASSAGE ON TUESDAY...PREFER COOLER GFS MOS
NUMBERS.
