Area forecast discussion, May 29, 4:59 AM EDT, 43 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
459 AM EDT TUE MAY 29 2012

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT

SHOWERS AND THUNDERSTORMS THIS MORNING...AND A COOLING TEMPERATURE
TREND THROUGH THE PERIOD ARE THE MAIN FORECAST ITEMS OF INTEREST.

COLD FRONTAL ZONE HAS BECOME MORE ACTIVE DURING THE OVERNIGHT HOURS
AS LARGE SCALE FORCING FOR ASCENT HAS INCREASED WITH THE APPROACH OF
BROAD UPPER TROUGH ACROSS THE UPPER MIDWEST. A COUPLE OF CORRIDORS
OF ENHANCED LOW LEVEL MOISTURE CONVERGENCE THIS MORNING...THE FIRST
EXTENDING FROM EAST CENTRAL INDIANA INTO NORTHWEST OHIO IN WEAK
PREFRONTAL CONFLUENT ZONE AND A SECOND STRONGER AREA OF MOISTURE
CONVERGENCE ASSOCIATED WITH THE COLD FRONT. SHOWERS AND STORMS
ASSOCIATED WITH THE COLD FRONT HAVE ALSO BEEN ENHANCED BY SEVERAL
OUTFLOW BOUNDARIES. WITH A NARROW CORRIDOR OF STEEP MID LEVEL LAPSE
RATES AND MODERATE INSTABILITY SHIFTING EAST WITH THE FRONT
EXPECTING A CONTINUATION OF PULSY TYPE ACTIVITY WITH SHORT LIVED
POTENTIALLY STRONG DOWNDRAFTS. GREATEST CONCENTRATION OF SHOWERS AND
STORMS EXPECTED ACROSS THE SOUTHEAST THIS MORNING WHERE MUCAPE AXIS
OF 1500-2000 J/KG AND SLIGHTLY STRONGER LOW LEVEL CONVERGENCE/OUTFLOW
INTERACTIONS ARE LIKELY TO RESIDE.

PRECIP TO SHIFT EAST OUT OF NORTHWEST OHIO COUNTIES BY MID TO LATE
MORNING. POST FRONTAL COLD ADVECTION TODAY NOT EXPECTED TO BE
PARTICULARLY STRONG HOWEVER UNTIL LATE IN THE DAY OR BY EARLY
EVENING. POST FRONTAL WEST NORTHWEST WINDS GENERALLY EXPECTED IN THE
10 TO 15 MPH RANGE TODAY...ALTHOUGH BY MID TO LATE AFTERNOON AS THIS
LOW LEVEL COLD ADVECTION BECOMES MORE PRONOUNCED...THERE MAY BE A
PERIOD OF GUSTIER WINDS LATE IN THE AFTERNOON AS MIXED LAYER
DEEPENS. WITH THIS DELAYED STRONGER LOW LEVEL COLD ADVECTION...HAVE
NUDGED UP HIGHS A FEW DEGREES ACROSS THE AREA WITH MID TO EVEN UPPER
80S NOT OUT OF THE QUESTION ACROSS THE FAR SOUTHEAST.

SECONDARY MID LEVEL TROUGH TO DROP INTO THE SOUTHERN GREAT LAKES
REGION TONIGHT...WITH STRONGER LOW LEVEL CAA PUSH ASSOCIATED WITH
THIS TROUGH AND MUCH COOLER CONDITIONS WITH LOWS IN THE LOWER TO MID
50S. SFC ANTICYCLONE ACROSS THE UPPER MIDWEST WILL BE THE MAIN
SYNOPTIC FEATURE THROUGH THE REMAINDER OF THE SHORT TERM...SLOWLY
BUILDING SOUTHEAST INTO THE LOCAL AREA. THERMAL TROUGH SHOULD BE
ANCHORED ACROSS GREAT LAKES REGION ON WEDNESDAY PROVIDING MUCH
COOLER TEMPERATURES...AT OR BELOW SEASONABLE NORMALS.

&&

.LONG TERM...
THURSDAY THROUGH MONDAY...AN UPPER LEVEL TROF WILL TOP A WEAK UPPER
LEVEL RIDGE AND MOVE INTO THE WESTERN GREAT LAKES REGION AT THE
START OF THIS PERIOD. OVERALL...THE ECMWF...GFS AND CANADIAN GEM
WERE STILL HAVING SIGNIFICANT DIFFERENCES AMONG THEMSELVES IN THE
DEVELOPMENT AND DEEPENING OF THIS TROF OVER THE WESTERN GREAT LAKES
REGION. FOR THIS PACKAGE...FAVOR THE ECMWF WHICH IS BEST IN LINE
WITH THE CPS ANALOGS AND IS THE MOST PROGRESSIVE OF THE MODELS.
THEREFORE...HAVE KEPT LIKELY RAIN CHANCES THURSDAY AND FRIDAY...WITH
DRY CONDITIONS STARTING FRIDAY NIGHT AND CONTINUING THROUGH THE END
OF THE PERIOD. HAVE HIGHS WARMING TO AROUND 80 BY TUESDAY...BUT
TEMPS MONDAY AND TUESDAY MAY BE CONSIDERABLY WARMER DEPENDING ON THE
LOCATION OF THE WARM FRONT.

&&

.AVIATION...
06Z TAFS...SHOWERS AND THUNDERSTORMS BEGINNING TO FILL IN ALONG
ADVANCING COOL FRONT FROM EAST CENTRAL ILLINOIS INTO MISSOURI. A
BROAD UPPER LEVEL TROUGH PUSHING INTO THE UPPER MIDWEST AND AN
ASSOCIATED UPPER SPEED MAX ARE PROVIDING ENOUGH LARGE SCALE LIFT
FOR THIS INCREASED CONVECTIVE COVERAGE. SFC BASED INSTABILITY HAS
WANED ALTHOUGH STEEP LAPSE RATES JUST ABOVE THE SFC COMBINED WITH
AN AXIS OF POOLED LOW LEVEL MOISTURE MOVING INTO WESTERN
INDIANA WITH THE FRONT SHOULD CONTINUE TO SUPPORT SHOWERS AND
EMBEDDED THUNDERSTORMS. GREATEST COVERAGE IS EXPECTED TO REMAIN
SOUTH OF KSBN ASSOCIATED WITH SLIGHTLY STRONGER LOW LEVEL
CONVERGENCE TO THE SOUTH BUT DO SEE POTENTIAL OF ISOLD THUNDER AT
KSBN IN THE 07Z TO 09Z TIMEFRAME. BETTER CHANCE OF THUNDERSTORMS
FOR KFWA TERMINAL WHERE HAVE MAINTAINED TEMPO TSRA IN THE 08Z TO
11Z WINDOW. WINDS TO SHIFT WEST NORTHWEST BEHIND THE FRONT LATE
TONIGHT...WITH SOME INCREASING GUSTINESS TO 20 KNOTS BY MID TO
LATE AFTERNOON AS COOL AIR ADVECTION INCREASES DEPTH OF MIXED
LAYER. WINDS TO DIMINISH LIGHT NORTHWEST WEDNESDAY EVENING AS SFC
HIGH PRESSURE BEGINS TO BUILD IN FROM THE UPPER MIDWEST.
