AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
113 PM EDT SAT SEP 8 2007

.AVIATION...18Z TAFS
HIGH END MVFR CIGS WILL LIKELY PREVAIL THIS AFTN AT FWA AS MOISTURE WILL
CONTINUE TO OVERRIDE A SFC BDRY IN PLACE NEAR A LAF TO FDY
LINE...JUST SOUTH OF THE FWA TERMINAL. CIGS NEAR 3KFT EXPECTED AT
SBN THIS AFTERNOON...WILL CARRY A TEMPO BKN025 THROUGH 20Z TO
ACCOUNT FOR MVFR CIGS NEARBY. THERE IS THE RISK FOR SCT
CONVECTION THIS AFTN...BEST CHANCES BEING CLOSER TO THE FRONT AT
FWA. WILL ADD A VCTS GROUP FOR FWA AND KEEP SBN DRY THROUGH 02Z.
SHRA ACTIVITY IS EXPECTED LATE THIS EVENING INTO TONIGHT AS A
CONVECTIVELY-INDUCED SHRTWV OVER SW MO WILL TRACK NEWD TOWARDS THE
NRN OH VALLEY. THIS ALONG WITH A STRONG SHRTWV TRACKING THROUGH
THE UPPER MIDWEST AND NRN LAKES WILL PROVIDE PLENTY OF DEEP LAYER
MOISTURE AND LIFT FOR PRECIP TONIGHT. WILL ADD A -SHRA GROUP AFTER
03Z IN SBN AND SHRA IN FWA AFTER 02Z...ALONG WITH VCTS MENTION AT
FWA WITH THE FRONT NEAR. SOME ELEVATED CONVECTION IS POSSIBLE IN
SBN BUT WILL LEAVE THUNDER MENTION OUT FOR NOW. UPSTREAM OBS AND
FCST SOUNDINGS INDICATE IFR AND LOW-END MVFR CIGS FOR TONIGHT INTO
SUNDAY MORNING. WINDS SHOULD REMAIN BLO 10KTS THROUGH THE TAF
PERIOD.

PREV DISCUSSION...
SHORT TERM...
MAIN ISSUE FOR SHORT TERM PERIOD WILL BE POSITION OF FRONTAL
BOUNDARY.  METARS SHOWING BOUNDARY PUSHING SE INTO CENTRAL IN EARLY
THIS MORNING.  EXPECT BOUNDARY TO LINGER TO THE S OF CWA AS ITS
ASSOCIATED SFC LOW STRENGTHENS AND MOVES NE OVER SRN CANADA.  A
SHORT/WV WILL APPROACH FROM THE SW TODAY TRACKING OVER SRN IN
INTO CENTRAL OH.  THIS WAVE WILL CAUSE THE FRONTAL ZONE TO PUSH BACK
NORTH INTO LOWER MI BY TONIGHT PROVIDING A TRIGGER FOR CONVECTION.
WITH LIMITED INSTABILITY CAUSED BY CLOUD COVER AND ADJACENT STABLE
AIR MASS JUST NORTH OF THE FRONT...EXPECT ANY THUNDERSTORMS TO
REMAIN BLO SEVERE.  WITH TRACK OF SHRT/WV THROUGH CENTRAL OH AIDED
BY 30-35KT H85 LLJ TONIGHT...BELIEVE SE CWA WILL HAVE THE BEST SHOT
FOR CONVECTIVE ACTIVITY.

TEMPS EXPECTED TO BE PROBLEMATIC ONCE AGAIN WITH SKIES ACROSS THE
NORTH LIKELY HAVING A PERIOD OF PARTLY SUNNY VS THE SOUTH WHICH MAY
REMAIN MOSTLY CLOUDY MUCH OF THE DAY. EXPECTING HIGHS IN THE MID TO
UPPER 70S ACROSS THE AREA. OVERNIGHT LOWS WILL THEN DROP OFF INTO
THE LOW TO MID 60S AS MSTR INCREASING AGAIN AND EXPECTED RAINFALL
ESPECIALLY SE.

LONG TERM...
WATER VAPOR IMAGERY CONTG TO SHOW SERIES OF SHRTWVS ALONG SRN
PORTION OF BROAD MEAN TROF OVER CANADA AND TOPPING RIDGE IN ERN
PACIFIC. STRONG SHRTWV WHICH AFFECTED OUR AREA TODAY WAS MOVG
INTO THE LWR GRTLKS AND OH VALLEY WITH SUB-TROPICAL MOISTURE
PLUME CONTG TO STREAM NE-ENE AHEAD OF IT. SFC CDFNT ASSOCIATED
WITH THIS SHRTWV HAS BECOME PARALLEL TO MID LEVEL FLOW AND THUS
SHOULD MAKE LITTLE ADDITIONAL SEWD PROGRESS. NEXT SHRTWV OF
INTEREST OVER MT THIS MORNING AND IS FCST TO MOVE TO NRN MN BY
12Z SUNDAY. BACKING FLOW AHEAD OF THIS SYSTEM SHOULD RESULT IN
SOME OVERRUNNING SHOWERS/TSTMS NORTH OF THE STALLED E-W BOUNDARY
OVER CENTRAL INDIANA, WHILE SFC CDFNT ASSOCIATED WITH THIS SYSTEM
SHOULD MOVE ACROSS THE CWA SUNDAY. NAM DEPICTION OF THESE EVENTS
APPEARS MORE REASONABLE THAN GFS WHICH APPEARS TO BE TOO DEEP WITH
LOW ALONG OLD BOUNDARY... PRBLY DUE TO CONVECTIVE FEEDBACK AND TOO
WK WITH NRN STREAM SYSTEM... PSBLY AS A RESULT OF OVERDEVELOPING
SRN STREAM SYSTEM LOW. NAM SOLUTION SUPPORTS GOING CHC OF TSTMS
ACROSS ALL BUT FAR NW PORTION OF THE CWA THROUGH THE DAY SUNDAY
WITH HIGHEST POPS SE CLOSEST TO STALLED OLD BOUNDARY AND WHERE
FROPA WILL OCCUR LATEST IN THE DAY ALLOWING FOR BETTER
DESTABILIZATION.

HIGH PRESSURE RIDGE SHOULD BUILD INTO THE WRN GRTLKS REGION BEHIND
THIS FRONT SUNDAY NIGHT PROVIDING FAIR WX. NEXT SHRTWV OF INTEREST
OVER BRITISH COLUMBIA THIS MORNING IS EXPECTED TO DIG SE TO THE
GRTLKS MON/MON NGT. ALTHOUGH THIS SYSTEM MAY PROVIDE SUFFICIENT MID
LEVEL LIFT IN OUR AREA TO SUPPORT A FEW SHOWERS, APPEARS AIRMASS
WILL BE STABLE ENOUGH BY THAT TIME TO PREVENT TSTMS AND HAVE THUS
REMOVED MENTION FOR THIS PERIOD. OTRWS, NO SGFNT CHANGES MADE TO FCST
BEYOND DAY3.
