AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
333 PM EDT MON APR 16 2012

.SHORT TERM.../TNGT-TUE NGT/

LOWEST GATES IN PROFILER NETWORK SHOWING GRADIENT WINDS GRADUALLY
SUBSIDING BUT STILL POTENTIAL TO REACH ADVISORY GUSTS SO WILL
MAINTAIN WIND ADVISORY THROUGH 23Z. WEAKENING GRADIENT AND LOSS OF
HEATING/MIXING SHOULD RESULT IN WINDS RAPIDLY DIMINISHING AROUND
SUNSET. RATHER STRONG CAA CONTG THIS AFTN WITH TEMPS UPSTREAM IN THE
U40S/L50S. SFC HIGH PRESSURE BUILDING INTO THE AREA ALONG WITH
CLEARING SKIES TONIGHT SHOULD ALLOW FOR GOOD RADIATIONAL COOLING.
MINS STILL EXPECTED TO BE IN THE M-U30S ACROSS THE AREA WITH PATCHY
FROST NORTH. SINCE GROWING SEASON ONGOING... WILL ISSUE A FROST
ADVISORY FOR THAT AREA.

HIGH EXPECTED TO MOVE SLOWLY EAST ACROSS THE GRTLKS TUE/TUE NGT
PROVIDING FAIR WEATHER WITH JUST SCT-BKN FAIR WX CU IN THE AREA
DURING THE DAY. SUFFICIENT SUNSHINE EXPECTED FOR GOOD MIXING WITH
HIGHS FCST TO RANGE FROM THE M50S NORTH-L60S SOUTH... WITH COOLER
TEMPS NEAR THE LAKE DUE TO LAKE BREEZE. SE RETURN FLOW SHOULD
DEVELOP TUE NIGHT BUT PRBLY STILL GOOD ENOUGH RADIATIONAL COOLING
OVERNIGHT FOR TEMPS TO FALL INTO THE M-U30S OVER MOST OF THE AREA
WITH PATCHY FROST PSBL AGAIN.

&&

.LONG TERM... /WEDNESDAY THROUGH MONDAY/

LOW PRESSURE WILL TRACK ACROSS THE NORTHERN GREAT LAKES WEDS NGT
INTO THURS WITH A COLD FRONT MAKING A RUN FOR THE FORECAST AREA.
MAJORITY OF SHORT AND MED RANGE MODELS BRING THE FRONT INTO THE
PROXIMITY OF THE AREA BUT THEN STALL IT OUT AS THE SOUTHERN
INFLUENCE OF A WEAK UPPER LEVEL WAVES SHEARS NORTH. WARM AIR WILL
RESIDE IN THE LOW LEVELS WITH 850 MB TEMPS IN THE +8 TO +12 CELSIUS
RANGE WEDS AND THURS. HOWEVER...FULL MIXING OF THIS MAY BE A
STRUGGLE DEPENDING ON AMOUNT OF CLOUD COVER ACROSS THE REGION.
WARMEST DAY WOULD APPEAR TO BE WEDS WHEN CLOUD COVER WILL STILL BE
ADVANCING IN FROM THE NORTH.

IN TERMS OF PRECIP...FRONT WILL NOT HAVE A LOT OF MSTR BEING CUT OFF
FROM GOOD RETURN FLOW FROM THE GULF. CHC POPS WARRANTED WEDS NGT
INTO THURS WITH HIGHEST VALUES NORTH CLOSER TO BETTER LIFT. SFC LOW
WILL DEVELOP AND TRACK ALONG THE FRONT FROM THE CENTRAL PLAINS INTO
THE SOUTHERN GREAT LAKES THURS NGT AND FRI. MED RANGE MODELS KEEP
THE BULK OF THE PRECIP NORTH OF THE FORECAST AREA WITH FAR N/NW
AREAS STANDING THE BEST CHANCE OF SEEING MEASURABLE RAINFALL. GIVEN
THIS TREND HAVE STILL HELD SHY OF LIKELY POPS IN THE NORTH WITH
GFS/ECMWF SHOWING BARELY A FEW HUNDREDTHS OF AN INCH.

THE TROUGH RESPONSIBLE FOR THE RAIN CHANCES INTO FRIDAY WILL RAPIDLY
DIG SOUTH AND INTENSIFY ACROSS THE GULF STATES AND EVENTUALLY CUTOFF
AND SLOWLY EJECT INTO THE APPALACHIANS BY MONDAY. THIS WILL RAISE
HAVOC WITH THE LAST FEW PERIOD OF THE FORECAST WITH MODELS SHOWING
THE UPPER LOW COMING BACK WEST FAR ENOUGH TO THROW RAIN CHANCES INTO
THE AREA. POSITION OF THE UPPER LOW WARRANTS LOW TO MID END CHC POPS
WITH HIGHEST IN THE EAST BY MONDAY. THE NE FLOW LIKELY ASSOCIATED
WITH THE UPPER LOW WILL KEEP TEMPS BELOW NORMAL AND POSSIBLY MUCH
COOLER THAN CURRENTLY DEPICTED IN THE GRIDS. SAVING GRACE MAY BE
CLOUD COVER WITH THE SYSTEM COULD HELP TO INSULATE THE REGION AND
LIMIT FROST POTENTIAL INTO NEXT WEEK.

&&

.AVIATION...

WOLCOTT PROFILER TIME/HEIGHT CONFIRMS MODEL FCSTS OF LOW LEVEL
GRADIENT GRADUALLY DECREASING AS DEEP LOW PRESSURE SYSTEM OVER
THE UPR GRTLKS MOVES NE AWAY FROM THE AREA. WIND GUSTS NEAR 40KT
AT START OF THE TAF PERIOD SHOULD SLOWLY DIMINISH THROUGH LATE
AFTN AND THEN RAPIDLY DIE DOWN WITH LOSS OF HEATING/MIXING AROUND
SUNSET. WRAP AROUND MOISTURE/LOW LEVEL INSTABILITY RESULTING IN
LOW VFR CLOUD CIGS AROUND THE AREA. SOME MVFR CIGS AND SPRINKLES
UPSTREAM ACROSS NRN IL ALONG SECONDARY CDFNT WHICH SHOULD MOVE
ACROSS NRN INDIANA THIS AFTN. CLOUD CIGS SHOULD DIMINISH THIS EVE
AS HEATING WANES AND LOW PULLS AWAY WITH JUST FEW/SCT CU/STRATO CU
EXPECTED REMAINDER OF THE TAF PERIOD.
