Area forecast discussion, Jul 18, 7:43 PM EDT, 4 hours before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
743 PM EDT WED JUL 18 2012

.AVIATION...

ONCE AGAIN A LOT OF UNCERTAINTY REGARDING CONVECTION AT TAF SITES
THIS PERIOD. RADAR SHOWING ISOLATED CONVECTION TO NW OF KFWA SO HAD
TO CONTINUE A VCTS FOR A FEW HOURS AS MOVEMENT IS TOWARD AIRPORT.
NEXT FOCUS IS ON CONVECTIVE COMPLEX IN WI AT 2330Z MOVING EAST.
TRAJECTORY SCHEMES ARE SPLIT ON THIS SYSTEM MOVING EAST AND TAKING A
DIVE SOUTHEAST TOWARD OUR AREA OVERNIGHT. MODELS NOT HANDLING THIS
FEATURE WELL WITH NAM12 CLOSE BUT SEVERAL HOURS OFF IT WOULD APPEAR.
HAVE HEDGED TOWARD A VCSH FOR NOW AT KSBN AND WILL HAVE TO MONITOR
TRENDS NEXT SEVERAL HOURS FOR LATE EVENING UPDATE OR INCLUSION OF
TSRA INTO 06Z TAFS. WEAK BOUNDARY STILL IN AREA ON THURSDAY WITH
DEGREE OF CONVECTION CONTIGENT ON WHAT OVERNIGHT SYSTEM DOES.
THEREFORE JUST A VCSH AT KFWA TOMORROW AT THIS JUNCTURE.

&&

.SHORT TERM... /TONIGHT THROUGH THURSDAY NIGHT/

COMPLICATED FORECAST OVER THE NEXT 24 TO 36 HOURS WITH NUMEROUS
FEATURES TO BE CONCERNED ABOUT FOR CONVECTIVE CHANCES AND EFFECTS ON
TEMPS.

CLUSTER OF STG-SVR TSTMS HAS NOW MOVED SOUTHEAST OF THE AREA.
ADDITIONAL ISOLATED STORMS CONTINUE TO DEVELOP SOUTH OF US 30 FROM
NE ILLINOIS TOWARDS ROCHESTER AND LOCATIONS SE. WHILE SOME STRONGER
CORES HAVE BEEN NOTED...THESE ARE BEHAVING AS EXPECTED WITH MORE OF
A PULSE NATURE AT THIS TIME WITH STRONGEST SHEAR REMAINING NORTH OF
THE AREA. WHILE AREAS EAST OF I-69 HAVE STABILIZED
SOMEWHAT...NUMEROUS BOUNDARIES REMAIN AND SOME HINTS OF
CLEARING/EROSION ON THE NW FRINGES OF THE CLOUD COVER RAISE AT LEAST
SOME CONCERNS. GIVEN THESE FACTORS...WILL ALLOW SVR TSTM WATCH TO
RIDE FOR THE TIME BEING. LOCATIONS NW OF THE RECENT CONVECTION HAVE
HAD A CHANCE TO DESTABILIZE WITH MANY LOCATIONS BACK INTO THE MID
80S TO LOWER 90S. WITH BOUNDARIES MOVING INTO THESE UNSTABLE
AREAS...ADDITIONAL STORMS MAY FIRE JUST ABOUT ANYWHERE...WITH
ISOLATED STRONG WINDS POSSIBLE. HAVE WENT PRE 1ST PERIOD AND WENT
CHC/SCT WORDING FOR THE TIME BEING. AS FOR REMAINING HEAT
ADVISORY...WILL LEAVE INTACT THROUGH EXPIRATION. AREAS HAVE COOLED
EAST OF 69 AND LIKELY WON'T RECOVER MUCH...BUT WITH SOME CLEARING
POSSIBLE AND SURROUNDING OFFICES CONTINUING...WILL KEEP HEADLINES
INTACT.

FOCUS THEN TURNS TO UPSTREAM COMPLEX OF STORMS TAKING SHAPE ACROSS
MN/IA/WI. TRENDS WOULD SUGGEST THESE SHOULD CONTINUE TO DEVELOP AND
MOVE SE TOWARDS THE REGION AS STATIONARY BOUNDARY REMAINS FOCUSED
ACROSS THE AREA. THIS ACTIVITY WOULD NOT LIKELY MOVE IN UNTIL LATER
TONIGHT. HAVE PLAYED POPS CONSERVATIVE TONIGHT WITH LOW END CHC FOR
THE TIME BEING AND PASS ONTO EVE SHIFT TO MONITOR UPSTREAM TRENDS. A
MUGGY NIGHT WILL BE IN STORE WITH LOWS AROUND 70 INTO THE LOWER 70S.

CHANCES FOR RAINFALL LOOK CONSERVATIVELY PROMISING DURING THE DAY
THURSDAY AS FRONTAL BOUNDARY WILL LIE ACROSS THE FORECAST AREA WITH
AN WEAK SFC WAVE AND AT LEAST SOME UPPER LEVEL ENERGY SET TO MOVE
THROUGH DURING THE AFTERNOON AND EVENING HOURS. WHILE GUIDANCE IS
PAINTING LIKELY TO CATEGORICAL POPS...HAVE INCREASED POPS COMPARED
TO PREV FORECAST...BUT HELD IN MID TO HIGH CHC RANGE WITH CONCERNS
ABOUT EXACT LOCATION OF FRONT AND OVERNIGHT/EARLY MORNING CONVECTION
AND/OR DEBRIS. THESE SAME CONCERNS WARRANT KEEPING SOMEWHAT COOLER
FOR TEMPS WITH HIGHS IN THE MID TO UPPER 80S. HOWEVER...GIVEN THE
WARM START...IF ANY AMOUNT OF CLEARING IS IN PLACE IN THE
MORNING...TEMPS WILL TOP 90 IN SEVERAL SPOTS AGAIN.

FINALLY INTO THURS NGT...CONVECTION MAY BE LEFT OVER...BUT SHOULD BE
ON THE DECREASE. HAVE LEFT THURS NGT UNTOUCHED IN TERMS OF SENSIBLE
WEATHER.
