AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
1124 PM EDT WED AUG 22 2007

.UPDATE...
UPDATE WAS SENT A BIT AGO TO INCREASE POPS NW AREAS TO REFLECT
CURRENT TRENDS OF MCS EXTENDING FROM CNTRL LWR MI BACK INTO
WISCONSIN AND ILLINOIS. OUTFLOW BOUNDARY WORKING ACROSS NW PART OF
THE CWA WITH LITTLE FANFARE AT THE MOMENT...BUT EXPECTING THIS TO
BEGIN TO FIRE OVERNIGHT AS IT INTERACTS WITH NOSE OF THETA E RIDGE
INTO THE CWA. CONVECTION HAS BEEN ON THE UPSWING ACROSS NE ILLINOIS
AND NOW FORMING ACROSS SRN LK MI.

&&

.AVIATION...

VFR CONDITIONS EARLY THIS EVENING BUT UPSTREAM CONVECTIVE COMPLEX A
CONCERN FOR OVERNIGHT. BEST LOW LEVEL JET AND FORCING SUGGEST THIS
COMPLEX WILL MOVE NORTHEAST BUT APPROACHING SHORT WAVE AIDING
DEVELOPMENT TO MOVE MORE EASTERLY. SLOW EASTWARD PROPAGATION
EXPECTED. RUC40 AND NAM40 SHOW 850MB THETA E AXIS NEAR MISSISSIPPI
RIVER TO ADVECT EAST AHEAD OF THIS LINE COUPLED WITH MODEST INCREASE
IN LOW LEVEL JET TO NEAR 25KT. ENOUGH INSTABILITY OVERNIGHT TO ALLOW
THESE FEATURES TO GENERATE ADDITIONAL TSRA ACROSS IL AND INTO IN AND
MICHIGAN OVERNIGHT. HAVE INCLUDED A TEMPO TSRA AT KSBN BUT WITH KFWA
FURTHER REMOVED HAVE OPTED TO BE OPTIMISTIC AT THIS TIME BUT WILL BE
CLOSELY MONITORED. EASTERN INDIANA IN AREA OF GOOD THETA E ADVECTION
OVERNIGHT BUT FARTHER REMOVED FROM SHORT WAVE. PLENTY OF LOW LEVEL
MOISTURE FOR MVFR BR BUT WITH LITTLE MORE WIND TONIGHT NOT AS
CONFIDENT IN IFR. AMOUNT OF DEBRIS CLOUDINESS IN THE MORNING WILL
ONCE AGAIN BE DEPENDANT ON DEVELOPMENT OVERNIGHT. MIXING AHEAD OF
FRONT SHOULD ALLOW VFR CONDITIONS TO DEVELOP WITH POSSIBILITY OF
AFTERNOON SCATTERED CONVECTION ONCE AGAIN.

&&

.SHORT TERM...

TONIGHT AND TOMORROW.

LATEST SFC ANALYSIS INDICATES WARM FRONT HAS LIFTED NORTH OF THE CWA
AND IS QUITE DIFFUSE EVEN ACROSS MI. HWVR, OBJECTIVE ANALYSIS
INDICATES WK MOISTURE CONVERGENCE AND EXTREMELY UNSTABLE AIRMASS
REMAINING OVER OUR CWA. ACARS/TAMDAR DATA SUGGESTS CONVECTIVE
TEMPS ARE IN THE U80S WHICH ARE BEING APPROACHED ATTM, SO STILL
ANTICIPATE SCT TSTMS TO DVLP THIS AFTN AND PERSIST INTO THE EVE.
COUPLE OF SHRTWVS MOVG THROUGH NEB/IA THIS AFTN WITH ASSOCIATED MCS
ACTIVITY SHOULD MOVE THROUGH WRN GRTLKS LATE TONIGHT AND THU. EXPECT
AT LEAST SCT STORMS ASSOCIATED WITH THE FIRST OF THESE SHRTWVS WILL
SURVIVE TO MOVE INTO OUR CWA OVERNIGHT AND EARLY THU. SWLY FLOW WILL
BECOME BETTER ESTABLISHED DURING THE DAY THU AS CDFNT APPROACHES
FROM THE NW. STRONGER MIXING ALONG WITH WK WAA SHOULD ALLOW TEMPS TO
REACH THE L-M90S FM N-S ACROSS THE AREA. IT WILL REMAIN HUMID BUT
WITH STRONGER WINDS, EXPECT A LITTLE DRIER AIR TO MIX DOWN TO THE
SFC DURING THE DAY DROPPING DWPTS TO AROUND 70... WITH RESULTANT
HEAT INDICES CLOSE TO ADVISORY CRITERIA OF 100. AIRMASS WILL AGAIN
BECOME VERY UNSTABLE AND WITH SOME FORCING IN THE AFTN ASSOCIATED
WITH SECOND SHRTWV MOVG INTO THE WRN GRTLKS... LEFT GOING CHC OF
TSTMS ACROSS THE AREA WITH HIGHEST POPS AGAIN NW.

&&

.LONG TERM...

TOMORROW NIGHT THROUGH WEDNESDAY.

THURSDAY NIGHT THE FRONT IS PROGGED TO BE HANGING AROUND JUST TO OUR
NORTHWEST...SO WILL BE CONTINUING THE HIGHER CHANCES FOR RAIN IN THE
NORTHWESTERN PART OF THE CWA THAN IN THE SOUTHEASTERN PART. THERE
HAS BEEN SOME WOBBLING OF THE FRONT IN THE MODELS ON FRIDAY...WITH
THE LATEST RUNS SHOWING THE FRONT STAYING JUST TO THE
NORTHWEST...BUT WILL REMAIN WITH THE 40 POP ACROSS THE CWA WITH SOME
UNCERTAINTY IN THE FRONTS EXACT LOCATION. THEN A LARGER DIFFERENCE
IN THE MODELS FOR FRIDAY NIGHT INTO SATURDAY. THE GFS HAS BROUGHT
THE FRONT THROUGH THE CWA ALREADY BY 12Z SATURDAY WHEREAS THE NAM
HAS IT THROUGH NORTHERN INDIANA TO A LOW IN NORTHERN ILLINOIS THEN
DOWN TO CENTRAL MISSOURI. SO THEN BY 00Z SUNDAY THE GFS IS WELL ON
ITS WAY TO MOVING HIGH PRESSURE INTO THE CWA AND THE NAM JUST HAS
THE FRONT INTO CENTRAL OHIO. WITH TIMING UNCERTAINTY...DID NOT ALTER
THE FORECAST FOR FRIDAY NIGHT AND SATURDAY. SATURDAY NIGHT AND
SUNDAY THOUGH IS LOOKING TO BE DRY WITH A HIGH PRESSURE IN PLACE.
OUR CWA THEN LOOKS TO BE DRY INTO THE FIRST PART OF NEXT WEEK. AN
ITEM TO WATCH FOR NEXT WEEK...ESPECIALLY THE TIMING...IS A POSSIBLE
FRONT. TIMING OF THIS FRONT IS ALSO SHAKY AT THE MOMENT BUT THE
POSSIBLE TIMING OF THIS FRONT IS LOOKING TO BE TUESDAY
NIGHT/WEDNESDAY. SO HAVE INTRODUCED A SMALL RAIN CHANCE FOR
THEN...WHICH COLLABORATES WELL WITH SURROUNDING OFFICES.
