AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
846 PM EDT SAT APR 9 2011

.UPDATE...

SFC BOUNDARY STRETCHING FROM NEAR VPZ TO NEAR MIE WILL LIFT
NORTHWARD TONIGHT AS LOW LEVEL WARM ADVECTION REALLY BEGINS TO
RAMP UP LATER THIS EVENING WITH 40 KNOT SOUTHWESTERLY LOW LEVEL
FLOW BRINGING WARM SECTOR NORTHWARD. STRENGTHENING LOW LEVEL
INVERSION UNDER THIS SCENARIO COULD AID IN PATCHY FOG
FORMATION...PARTICULARLY ACROSS THE FAR NORTH. VSBYS ALREADY HAVE
LOWERED INTO THE 5 TO 7 MILE RANGE ACROSS SOME LOCATIONS AND HAVE
ADDED PATCHY FOG FOR FAR NORTHERN ZONES TONIGHT. SCATTERED
THUNDERSTORMS HAVE DEVELOPED ACROSS NORTHWEST IOWA INTO SOUTHERN
MINNESOTA WITH ADDITIONAL DEVELOPMENT LIKELY OVERNIGHT SPREADING
INTO THE WESTERN GREAT LAKES REGION...BUT PRIMARILY NORTH OF WFO
IWX FORECAST AREA IN ASSOCIATION WITH A RETREATING WARM FRONT AND
A FEW LEAD IMPULSES EJECTING NORTHEASTWARD FROM WESTERN CONUS
UPPER TROUGH. DID MAINTAIN SLIGHT CHANCE POPS ACROSS THE FAR NORTH
INTO EARLY SUNDAY MORNING BUT THERMODYNAMIC PROFILES SHOULD
SUPPORT BETTER CHANCE FOR THUNDERSTORMS NORTH OF THE FORECAST
AREA. TEMPERATURES ALSO IN DECENT SHAPE AND AREAS ACROSS THE
CENTRAL AND NORTHERN PORTIONS OF THE FORECAST AREA MAY NOT SEE
TEMPERATURES DROP TOO MUCH FURTHER WITH INCREASING LOW LEVEL WARM
ADVECTION OVERNIGHT. UPDATE WILL BE SENT MAINLY TO ACCOUNT FOR
POSSIBILITY OF SOME PATCHY FOG...OTHERWISE NO MAJOR CHANGES.

.PREV DISCUSSION... /ISSUED 806 PM EDT SAT APR 9 2011/

AVIATION...

SFC WARM FRONT SITUATED FROM NORTHWEST INDIANA INTO CENTRAL
INDIANA WILL LIFT NORTHWARD TONIGHT AND MAIN AVIATION FORECAST
QUESTION DEALS WITH POTENTIAL OF LOW CLOUDS REDEVELOPING WITH THIS
NORTHWARD RETREATING BOUNDARY. THERE DOES APPEAR TO BE SOME
DIURNALLY ENHANCED CONVECTIVE CONTRIBUTION TO 2-3K FT CLOUDS ALONG
AND NORTH OF THIS BOUNDARY AND DO SEE SOME POTENTIAL OF SOME MVFR
CIGS REDEVELOPING ALONG AND NORTH OF THIS FRONT THROUGH 06Z BEFORE
FRONT LIFTS NORTH NORTHEAST OF THE AREA WHICH SHOULD EVENTUALLY
TAKE THREAT OF MVFR CIGS TO THE NORTH AND EAST OF THE AREA. OTHER
QUESTION WILL BE ON POTENTIAL FOG DEVELOPMENT WITH PERHAPS BEST
POTENTIAL IN THE 03Z- 09Z TIMEFRAME BEFORE EFFECTS OF WARM FRONT
MAY MAKE VSBY REDUCTIONS LESS PROBABLE. THIS CURRENT THINKING IS
ALREADY REFLECTED IN CURRENT TAFS AND ONLY CHANGE MADE TO PREVIOUS
TAFS WAS TO HINT AT POSSIBLE MVFR DECK REDEVELOPMENT A BIT SOONER
THIS EVENING BASED ON WARM FRONTAL POSITION AND CURRENT SATELLITE
TRENDS. LOW LEVEL HEIGHT FALLS IN THE PLAINS/UPPER MIDWEST WILL
RESULT IN A STRENGTHENING LOW LEVEL JET LATE TONIGHT AS WARM
SECTOR LIFTS NORTHWARD. WITH LOW LEVEL INVERSION BEING REINFORCED
IN THIS STRONG WARM ADVECTION...PREVIOUS INCLUSION OF LLWS ALSO
APPEARS TO BE REASONABLE AT THIS TIME...ESPECIALLY AFTER 09Z.

PREV DISCUSSION... /ISSUED 333 PM EDT SAT APR 9 2011/

SHORT-TERM...THIS AFTERNOON THROUGH SUNDAY NIGHT

SUBSIDENCE BEHIND A DEPARTING MCS AND NORMAL DIURNAL EFFECTS HAVE
ALLOWED LOW STRATUS TO THIN OUT ACROSS THE WESTERN HALF OF THE FA AS
OF 19Z. THIS TREND SHOULD CONTINUE TO SPREAD EAST...LEAVING A HAZY
SUNSHINE FOR THE REMAINDER OF THE AFTERNOON. THIS WILL ALLOW FOR A
LATE JUMP IN TEMPS WITH HIGHS RANGING FROM NEAR 60F IN THE FAR NE TO
THE MID 70S IN THE FAR SW.

STATIONARY SFC FRONT...NOW JUST SW OF THE FA...WILL FINALLY MIX NWD
LATE TONIGHT PER INCREASING LOW LVL SOUTHWESTERLY FLOW TIED TO SFC
CYCLOGENESIS OVER THE UPPER MIDWEST. LOW STRATUS MAY REDEVELOP
TONIGHT...ESPECIALLY IN THE NORTH AND EAST...JUST NORTH OF THE
BOUNDARY AS THE EVER PERSISTENT LOW LEVEL THERMAL INVERSION
LINGERS. MEANWHILE...CONVECTION WILL LIKELY FIRE ACROSS THE UPPER
MIDWEST THIS EVENING AND THEN TRACK INTO WI AND THE NORTHERN TWO
THIRDS OF LOWER MI BY LATE TONIGHT INTO SUNDAY MORNING. WITH THE
WARM FRONT NEAR...AND INCREASING ISENTROPIC UPGLIDE WITHIN THE
SURGING LOW LVL THETA-E RIDGE...OPTED TO CONTINUE WITH A SLIGHT
CHC MENTION IN THE FAR NORTH LATE TONIGHT INTO SUNDAY MORNING.

WARM SECTOR WILL BECOME FIRMLY ENTRENCHED ACROSS THE CWA ON SUNDAY
WITH AFTERNOON HIGHS PROGGED TO REACH THE LOW TO MID 80S. THIS
COMBINED WITH SFC DEWPOINTS AOA 60F WILL LEAD TO UNSTABLE
CONDITIONS WITH SBCAPE/S APPROACHING 1500 J/KG. ALTHOUGH...AM NOT
ANTICIPATING ANY AFTERNOON CONVECTION LOCALLY GIVEN NO OBVIOUS
TRIGGER AND A RATHER STRONG CAP THAT WILL BE IN PLACE.
OTHERWISE...IT WILL BE BREEZY TOMORROW WITH BUFKIT MOMENTUM
TRANSFER PROGS HINTING AT GUSTS NEAR 30 KNOTS.

HEIGHT FALLS ASSOCIATED WITH AN UPPER UPPER TROUGH EJECTING INTO THE
CENTRAL CONUS WILL OVERSPREAD THE WARM SECTOR ON SUNDAY. THIS SHOULD
HELP BREAK THE CAP ACROSS WI SOUTHWEST INTO NRN IL AND FAR EASTERN
IA...WITH SEVERE STORMS EXPECTED TO DEVELOP ALONG A PRE-FRONTAL
TROUGH IN THIS AREA LATE SUNDAY AFTERNOON INTO EARLY SUNDAY EVENING.
ADDITIONAL MID LEVEL ENERGY AND ITS ASSOCIATED 100 KT PLUS MID LEVEL
JET ROTATING THROUGH THE BASE OF THE AFOREMENTIONED UPPER TROUGH
WILL PIVOT NEWD INTO THE MID MS VALLEY/SRN GREAT LAKES SUNDAY NIGHT.
THIS WILL LIKELY ALLOW CONVECTION TO FILL IN SWD ALONG THE
PRE-FRONTAL TROUGH SUNDAY EVENING AND POTENTIALLY MOVE THROUGH THE
FA AS AN ORGANIZED QLCS LATE SUNDAY EVENING INTO THE OVERNIGHT
HOURS. A FAVORABLE SHEAR PROFILE AND INITIAL UNSTABLE LOW LEVEL
ENVIRONMENT SUPPORTS A SUSTAINABLE CONVECTIVE SYSTEM SUNDAY NIGHT
WITH WIND DAMAGE THE PRIMARY CONCERN. HOWEVER...POOR DIURNAL TIMING
AND STRONG INITIAL CAP/CIN MAY KEEP THIS FROM BECOMING A SEVERE
WEATHER MAKER THIS FAR EAST GIVEN THE STABILIZING BOUNDARY
LAYER...ESPECIALLY IF A SLOWER SOLUTION COMES TO FRUITION. WILL
CONTINUE WITH SEVERE/DAMAGING WIND WORDING IN THE GRIDS LATE
SUNDAY NIGHT.

LONG TERM...

LONG TERM CHALLENGES FOCUSED ON BEGINNING AND END OF PERIOD WITH TWO
POTENT SYSTEMS THAT WILL IMPACT OUR AREA. MODEL PREFERENCES ARE WITH
A BLEND OF MODELS IN THE EARLY PORTION OF FORECAST WITH PREFERENCE
TOWARD ECMWF IN LATTER PERIODS.

POTENTIALLY SEVERE SQUALL LINE EXPECTED TO BE MOVING THROUGH THE
AREA EARLY MONDAY MORNING. QUESTIONS REMAIN ON TIMING AS MODELS
CONTINUE TO STRUGGLE WITH TIMING AND DEVELOPMENT. EASTERN HALF OF
AREA STILL REMAINS FAVORED ON MONDAY MORNING FOR THUNDERSTORMS.
DEGREE OF SEVERE POTENTIAL REMAINS CLOUDY FOR THIS TIME PERIOD GIVEN
THE EARLY MORNING NATURE AND MODEL UNCERTAINTY ON LOCATION. STRONG
ENOUGH DYNAMICS ALOFT TO CERTAINLY SUPPORT A SEVERE THREAT WITH THIS
LINE WHEREVER IT IS ACTUALLY LOCATED.

DRY SLOT TO MOVE IN DURING THE DAY MONDAY WITH WRAP AROUND MOISTURE
AND SHOWER POTENTIAL INTO MONDAY NIGHT WITH UPPER TROUGH. TUESDAY
AND WEDNESDAY LOOKING NICE WITH HIGH PRESSURE SLIDING IN AND UPPER
RIDGE BUILDING ACROSS THE REGION AS ANOTHER WEST COAST TROUGH
DEVELOPS. THIS WILL LEAD TO ANOTHER POTENT SURFACE LOW DEVELOPMENT
IN THE PLAINS THURSDAY. GFS REMAINS FAST WITH ITS USUAL BIAS IN
MOVING UPPER LOWS EAST TOO FAST AND BRINGS SHOWERS INTO THE AREA
THURSDAY. PREFERENCE AT THIS TIME CONTINUES WITH ECMWF AND LATEST
12Z RUN CONTINUES TO BE SLOWER WITH EASTWARD PROGRESSION OF UPPER
LOW...KEEPING PCPN WEST OF THE AREA UNTIL FRIDAY. THEREFORE PREFER
NOT TO INTRODUCE POPS INTO THURSDAY PERIOD UNTIL BETTER AGREEMENT IS
SEEN.
