AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
202 PM EST MON JUL 4 2005

.SHORT TERM...
TONIGHT AND TUESDAY

VISIBLE SATELLITE IMAGERY THIS AFTN WAS SHOWING DEVELOPING
CONVECTION FROM SERN WISCONSIN...S AND SWWD INTO ERN IL...CNTRL
IL...THEN INTO SERN MO.  THIS CONVECTION WAS DEVELOPING ALONG A
PREFRONTAL TROF/BOUNDARY.  LOW LVL MSTR CONV/DEWPOINT POOLING WAS
OCCURRING AHEAD OF THIS BOUNDARY.  THIS FEATURE WILL BE THE FIRST
ROUND OF SHOWERS AND THUNDERSTORMS INTO THE REGION LATE THIS AFTN
AND EVENING.  WITH SFC TO 6 KM DEEP LAYER SHEAR EXCEEDING 30 KTS
(MODERATE SHEAR)...SBCAPES BETWEEN 2000 J/KG AND 3000 J/KG (MODERATE
INSTABILITY)...AND SOME VEERING WINDS WITH HEIGHT (LEADING TO STORM
ORGANIZATION)...SOME OF THE STORMS COULD BE SEVERE WITH DAMAGING
WINDS AND LARGE HAIL THE PRIMARY SEVERE WX THREATS.  ATTM...AM
PLANNING ON SEVERE WX WORDING IN ZONES FOR ROUGHLY THE ERN TWO
THIRDS OF THE CWFA FOR THIS EVENING.  WILL HOLD OFF ZONE ISSUANCE AS
LONG AS POSSIBLE TO SEE WHAT SPC/S NEXT MOVE WILL BE IN TERMS OF
ISSUING A WATCH BOX FOR OUR AREA.

THEN...LATER THIS EVENING AND OVERNIGHT...AN UPR LVL S/WV WILL MOVE
FROM MISSOURI INTO NRN INDIANA BETWEEN 00Z AND 09Z. THE DPVA ASSOCD
WITH THIS FEATURE WILL COMBINE WITH SUBSTANTIAL UPR DIV FROM RR QUAD
OF JET MAX OVER ONTARIO. THIS UPR LVL ASCENT WILL COMBINED WITH
LOW LVL SFC TO 850 MB CONVERGENCE AHEAD OF COLD FRONT JUST WEST OF
AFOREMENTIONED BOUNDARY.  AS A RESULT OF A GOOD LOW LVL CONV/UPR DIV
COUPLET...SHOWERS AND THUNDERSTORMS WILL INCREASE IN COVERAGE ACRS
THE WRN/SWRN CWFA BETWEEN 03Z AND 06Z...SPREADING EASTWARD DURING
THE OVERNIGHT HOURS.  WITH PRECIPITABLE WATER VALUES RANGING BETWEEN
1.5 TO 2 INCHES...WILL MENTION SOME LOCALLY HEAVY RAIN POSSIBLE.

COLD FRONT WILL BE ROUGHLY THROUGH HALF THE CWFA BY 12Z
TUESDAY...PUSHING EAST OF THE REGION BY 18Z.  SHOWERS AND
THUNDERSTORMS WILL LIKELY STILL BE ON GOING ACRS THE ERN ONE THIRD
OF THE CWFA...WHILE A FEW SHOWERS WILL LINGER BEHIND THE COLD
FRONT.  SKIES WILL GRADUALLY BECOME PARTLY CLOUDY FROM NW TO SE AS
SOME DRIER AIR FROM THE SFC TO 850 MB MOVES INTO THE FCST AREA FROM
THE NORTHWEST.

AS FOR TEMPS...CURRENT FCST OVERNIGHT LOWS IN THE MID AND UPPER 60S
LOOK GOOD...SO WILL NOT CHANGE.  HIGHS ON TUESDAY WILL RANGE FROM
THE MID AND UPPER 70S ALONG THE LAKE MICHIGAN SHORE LINE...TO THE
LOWER AND MID 80S ELSEWHERE...WHICH IS PRETTY MUCH IN LINE WITH MOST
MOS GUIDANCE...AND THIS SEEMS REASONABLE GIVEN 1000 MB-850 MB
THICKNESS SCHEMES AND 850 MB TEMPS.

&&

.LONG TERM...
TUESDAY NIGHT THROUGH MONDAY

ZONAL FLOW AT THE BEGINNING OF THE MEDIUM RANGE FORECAST PERIOD WILL
TRANSITION INTO A MORE AMPLIFIED PATTERN ACROSS NOAM BY THE END OF
THE WEEK WITH A DEEP GULF OF ALASKA TROUGH DIGGING INTO THE PAC NW
AND BRITISH COLUMBIA WITH DOWNSTREAM RIDGING BUILDING ACROSS THE
CENTRAL CONUS. A MEAN TROUGH WILL ALSO PERSIST ACROSS SOUTHEAST
CANADA THROUGH THE NEXT 7 DAYS.

SYSTEM IN THE SHORT RANGE PORTION OF THE FORECAST WILL MOVE EAST AND
EXIT BY TUESDAY EVENING WITH DRYING AND SUBSIDENCE SUPPORTING A
GENERAL DECREASE IN CLOUDINESS TUES NGT. NAM/GFS MORE AGGRESSIVE ON
TODAYS RUNS IN BRINGING A SECONDARY SHORTWAVE AND ATTENDANT SURFACE
TROUGH SOUTH THROUGH THE CWA WED PM AND EVENING. GFS LOOKS TO BE
OVERDONE IN CLOSING OFF A MID LEVEL CIRCULATION CENTER WED NIGHT AND
THURS OVER THE EASTERN GREAT LAKES. GIVEN THE CHANGE FROM CONTINUITY
ON THIS LATEST NCEP MODEL ITERATION WILL STICK WITH THE GOING DRY
FORECAST AND AWAIT FUTURE MODEL SUPPORT BEFORE ADDING ANY CHANCE
POPS.

THURSDAY THROUGH SATURDAY SURFACE HIGH PRESSURE WILL SETTLE OVER THE
GREAT LAKES AND OHIO VALLEY AND BEGIN YET ANOTHER LONG PERIOD OF DRY
WEATHER. THE INITIALLY COOL H85 TEMPS ON WEDNESDAY WILL SLOWLY CLIMB
EACH DAY WITH HIGH TEMPS BACK TO THE UPPER 80S TO NEAR 90 BY NEXT
WEEKEND. HUMIDITY LEVELS WILL STAY RELATIVELY LOW THROUGH THE REST
OF THE WEEK AND THEN BEGIN TO INCREASE NEXT WEEKEND AS DEEPER
SOUTHERLY RETURN FLOW DEVELOPS ON THE BACKSIDE OF THE DEPARTING
SURFACE HIGH. MEDIUM RANGE MODEL GUIDANCE CONTINUES TO SHOW A MORE
ROBUST SHORTWAVE DIGGING INTO SOUTHEAST CANADA THIS WEEKEND THAT MAY
DRAG A WEAK COLD FRONT THROUGH THE GREAT LAKES. WITH MODEL
UNCERTAINTIES AND THE LACK OF STRONG UPPER LEVEL SUPPORT AND DEEP
MOISTURE WILL CONTINUE WITH A DRY FORECAST FOR THE UPCOMING WEEKEND
UNTIL DETAILS BECOME MORE CLEAR. OTHERWISE MID/UPPER LEVEL RIDGING
WILL SLOWLY BUILD ACROSS THE CENTRAL CONUS THIS WEEKEND WITH HEAT
BEGINNING TO SPREAD EAST OUT OF THE PLAINS TOWARD THE MISSISSIPPI
VALLEY.

&&

.AVIATION...
18Z-18Z.

SFC ANALYSIS AND VISIBLE SATELLITE IMAGERY AT 17Z DEPICTED A
PREFRONTAL TROF/BOUNDARY FROM SE WISCONSIN INTO ERN AND CNTRL IL.
THIS PREFRONTAL TROF/BOUNDARY WILL CAUSE SHOWERS/THUNDERSTORMS TO
DEVELOP ALONG AND AHEAD OF IT.  THESE SHOWERS/STORMS MAY AFFECT THE
KSBN TAF SITE BETWEEN 20Z AND 24Z.  THEREAFTER...A COLD FRONT JUST
TO THE WEST OF THE PREFRONTAL TROF/BOUNDARY WILL MOVE TOWARD THE
REGION.  THE FRONTAL ZONE WILL INTERACT WITH A MOIST AND STABLE
AIRMASS.  NAM AND GFS 12Z MODELS ALSO CONTINUE TO PIVOT A
SUBSTANTIAL S/WV FROM MISSOURI INTO NRN/CNTRL INDIANA BY 06Z.  THE
LIFT FROM THE S/WV (AND UPR JET SUPPORT ) COMBINED WITH INCREASING
LOW LVL CONV FROM THE SFC TO 850 MB WILL CREATE A WIDESPREAD SHOWER
AND THUNDERSTORM CLUSTER ACRS ERN IL/INDIANA LATER THIS EVENING INTO
THE EARLY MORNING HOURS.  LOCALLY HEAVY RAIN WILL CREATE IFR VSBYS
WITHIN THUNDERSTORMS.  THE CLUSTER OF SHOWERS AND THUNDERSTORMS WILL
LIKELY WEAKEN SOME IN INTENSITY AS IT PUSHES EAST INTO ERN
INDIANA/WRN OHIO OVERNIGHT...BUT THE COVERAGE SHOULD STILL BE FAIRLY
SUBSTANTIAL TO INCLUDE WIDESPREAD CONDITIONS AT THE KFWA TAF SITE.

THE COLD FRONT WILL BE LOCATED ACRS SE MICHIGAN/ERN INDIANA BY 12Z
AND EAST OF THE CWFA BY 15Z. ONCE THIS FRONT PASSES...MOSTLY CLOUDY
SKIES CAN BE EXPECTED THROUGH 18Z WITH CIGS EXPECTED TO IMPROVE TO
THE VFR CATEGORY.
