AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
738 PM EDT TUE JUN 3 2008

.AVIATION...

COMPLICATED AVIATION FORECAST ONCE AGAIN WITH NUMEROUS BOUNDARIES
AND CONVECTIVE COMPLEX DEVELOPMENT EXPECTED OVER NEXT SEVERAL HOURS.
CURRENTLY WATCHING BOUNDARY LIFTING NORTHEAST THROUGH ILLINOIS. THIS
APPEARS TO BE ON NOSE OF DEVELOPING MODEST LOW LEVEL JET AND THETA E
MAX. COMPLICATING THIS SITUATION IS LAKE BOUNDARY MOVING SOUTH OFF
OF LAKE MICHIGAN. WAITING TO SEE IF THIS INTERSECTION FIRES ANY
CONVECTION NEXT HOUR OR SO. IF IT DOES...KSBN WILL NEED UPDATE.
OTHERWISE WITH LOW LEVEL JET THROUGH THE NIGHT AND MOIST LOW LEVELS
EXPECT CONVECTIVE COMPLEX UPSTREAM SIMILAR TO LAST NIGHT.
TRAJECTORIES ONCE AGAIN FAVOR AREAS JUST TO SOUTH OF TAF SITES BUT
WITH THETA E ADVECTION COULD SEE DEVELOPMENT IN TAF VICINITIES AS
WELL. WILL HAVE TO MONITOR FOR LATER UPDATES AS UNCERTAINTY IS QUITE
HIGH. WINDS ALSO RATHER LIGHT NEAR BOUNDARY ACROSS AREA. IFR CIGS
AND MVFR VIS POSSIBLE BUT AGAIN DEPENDENT ON BOUNDARY LIFTING NORTH
AND RESULTANT WIND FIELDS.

.SHORT TERM...
MCV ROTATING INTO NW IN ATTM W/RAPIDLY DECAYING SRN EXTENT TO
STRATIFORM RAIN SHIELD IN RESPONSE TO ENLARGING WAKE DEPRESSION AND
LOSS OF SIG LL MSTR FLUX DUE INTENSE CONVN WORKING THROUGH SRN IN
ALG COMPOSITED OUTFLW BNDRY FM EARLIER MORNING/OVERNIGHT MCS AND
WHICH EXTENDS UPSTREAM INTO NE MO W/RENEWED RECENT CONV DVLPMNT
THERE
AND BEST ASSIMILATED BY 12Z GFS WHICH FIRES ANOTHER MCS ACRS WRN IL
THIS EVENING AND THEN ROLLS EWD THROUGH CNTRL/SRN IN AFT MIDNIGHT.
HWVR GROSS SHRT TERM SIGNAL AUGMENTED VIA SFC/SAT OBS SUGGESTS LTL
SPRT OVERNIGHT SAVE FAR SOUTH IN PROXIMITY TO STALLED OUTFLW AND
VEERED WSWLY LLJ DVLPMNT YET ORIENTATION OF OUTFLW BNDRY DOES NOT
LOOK VRY CONDUCIVE. WILL SCALE MENTION BACK SOMEWHAT AT THIS POINT
ALTHOUGH HESITANT TO DROP TO CHC MENTION GIVEN RUC POSITIONING OF
VRY UNSTABLE THETA-E WEDGE INTO WRN IL. OTHERWISE VAPOR SHOWS LTL
MECHANISM ALOFT UPSTREAM TO LATCH ONTO OTHER THEN MID LVL TROUGH OVR
CO WHICH LIFTS OUT INTO THE SOUTHERN LAKES WED AFTN. GIVEN OBVIOUS
POTENTIAL OF FUTURE MESOSCALE COMPLICATIONS CAN NOT SEE ANY
JUSTIFICATION FOR ANYTHING OTHER THEN MID RANGE CHC POPS WED/WED
NIGHT ESP IN LIGHT OF EXTREMELY CONFLICTED INDIVIDUAL MODEL SIGNALS.

.LONG TERM...
THURSDAY THROUGH TUESDAY

VERY MINOR CHANGES MADE TO ONGOING FORECAST. BASIC UPPER LEVEL
PATTERN WILL REMAIN LOCKED THROUGH MUCH OF THE PERIOD FEATURING
UPPER LEVEL RIDGING OVER THE EASTERN CONUS WITH MEAN TROUGHING IN
THE WESTERN CONUS. PATTERN WILL FAVOR A WARM PERIOD WITH ABOVE
NORMAL TEMPS EXPECTED THROUGH THE PERIOD. CONTINUED TO FOLLOW THE
CONSISTENT AND REASONABLE ECMWF SOLUTION WHICH AGREES WELL WITH THE
LATEST MEAN NAEFS/GEFS/MREF SOLUTIONS. GIVEN THE MAGNITUDE OF
RIDGING EXPECTED OVER THE EASTERN CONUS PER PLUS 1 STANDARD
DEVIATION MREF H85 TEMP PROGS FRI/SAT AND AGAIN MONDAY. BEST CHANCE
FOR ANY ORGANIZED PRECIP STILL FAVORS FRIDAY NIGHT INTO SAT AS A
RATHER POTENT MID LEVEL WAVE WILL TRAVERSE THE GREAT LAKES.
ALTHOUGH FORECAST MODELS CONTINUE TO TREND THIS WEAVE FARTHER NORTH
GIVEN THE INTENSITY OF THE DEVELOPING RIDGE.

THURSDAY...ALLOWED LOW CHANCE POPS TO RIDE IN THE NORTH GIVEN
CONCERN
ON SPEED OF RETREATING WARM FRONT AND ORIENTATION OF H5 FLOW. BUT
WITH CAPPING PROGGED IN GFS/NAM BUFFER DATA...ITS NOT LOOKING TOO
FAVORABLE AT THIS POINT.

FRIDAY INTO SATURDAY...MEAN ENSEMBLE RUNS AND GFS/ECMWF SOLUTIONS
CONTINUE TO SUPPORT THE EJECTION OF A DIGGING WESTERN CONUS TROUGH.
THIS FEATURE WILL QUICKLY PUSH NE INTO THE GREAT LAKES BY FRIDAY
EVENING...SUPPORTING LARGE SCALE ASCENT AND ELIMINATION OF ANY
REMAINING CAP. HOWEVER...FRONTAL FORCING AND BEST FLOW IS EXPECTED
TO
PASS NW OF THE CWA...LEAVING ONLY CONVECTIVE PROCESS AS THE THE SOLE
FORCING MECHANISM...AS THE ASSOCIATED FRONT WASHES OUT.
HENCE...WILL LEAVE 50 POP IN THE FORECAST FOR NOW...GIVEN
UNCERTAINTIES ON CONVECTIVE SYSTEM DEVELOPMENT/MAINTENANCE AND
PROPAGATION. HAVE PUSHED PRECIP LATER IN THE SE GIVEN TREND OF
LATER SYSTEM ARRIVAL. CARRIED PRECIP CHANCES INTO THE ENTIRE DAY
SAT WITH WASHED OUT FRONTAL BOUNDARY/TROUGH CONTINUING ITS SLOW
EASTWARD MOVEMENT TROUGH THE CWA UNDER DECENT CAPE/CIN PROFILES.

SAT THROUGH TUESDAY...UPPER LEVEL RIDGING WILL AGAIN FAVOR THE THE
REGION WITH WAA SUPPORTING H85 TEMPS OF 18 TO 20 C THROUGH TUES. GFS
CONTINUES TO TRY AND FLATTEN THE RIDGE WITH THE EJECTION OF A
WESTERN CONUS TROUGH IN THE MON-TUES TIME FRAME. HOWEVER...GIVEN
VERY WARM H85 TEMPS AND STRONG NATURE OF THE PROGGED RIDGE PER H85
T STANDARD DEVIATION NOTED ABOVE...HAVE RETAINED DRY FORECAST
MONDAY...AND INTRODUCED A DRY TUESDAY UNTIL FURTHER CONSENSUS IS
REACHED.
