Area forecast discussion, May 24, 3:22 PM EDT, 3 hours 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
322 PM EDT TUE MAY 24 2011

.SHORT TERM

TONIGHT THROUGH THURSDAY MORNING...

UNSETTLED PATTERN TO PERSIST THROUGH THE PERIOD AS THE NEXT IN
SERIES OF SYSTEMS EJECTS OUT OF THE PLAINS INTO THE GREAT LAKES
REGION. IN THE NEAR TERM...SHORTWAVE OVER WISCONSIN HAS SHIFTED
ACROSS LAKE MICHIGAN AND THIS HAS TRIGGERED CONVECTION ALONG A WEAK
FRONTAL BOUNDARY.  THIS BOUNDARY IS EVIDENT IN THE SURFACE
TEMPERATURE AND WINDS WITH PRONOUNCED CONVERGENCE FROM NORTH CENTRAL
ILLINOIS INTO SOUTHERN MICHIGAN. WIND PROFILES WOULD SUPPORT SLOW
MOVING STORMS/REDEVELOPING ALONG THE BOUNDARY. SHOULD SEE THIS SHIFT
SOUTH AND END AFTER SUNSET TONIGHT.

THE NEXT SYSTEM EJECTS OUT OF THE PLAINS AND THIS WILL BE THE MORE
LIKELY TO PRODUCE STRONG TO SEVERE THUNDERSTORMS OVER THE FORECAST
AREA. MODELS ARE IN GENERAL AGREEMENT WITH THE SYSTEM EJECTING
THROUGH...BUT THE USUAL TIMING AND PLACEMENT ISSUES LEND SOME
UNCERTAINTY TO THE PLACEMENT OF THE MOST SIGNIFICANT THREAT.
PRECIPITABLE WATER AMOUNTS ARE QUITE HIGH WITH ALL THE MODELS AND
GIVEN THE RECENT ROUND OF RAINFALL THAT OCCURRED SUNDAY/MONDAY WILL
HAVE TO CLOSELY MONITOR THE RAINFALL AMOUNTS WITH THIS EVENT.

AT THIS TIME WILL CONTINUE SEVERE THREAT IN THE HAZARDOUS WEATHER
OUTLOOK AND MAINTAIN CURRENT TIMING AND PLACEMENT IN THE GRIDDED
FORECAST.

.LONG TERM.../THURSDAY THROUGH TUESDAY/

STRONG BUT OCCLUDING AND WKNG LOW WILL MOVE NE INTO OUR AREA THU.
MOIST AIRMASS SHOULD REMAIN IN PLACE OVER THE AREA THU WITH LOW
LEVEL MOISTURE CONVERGENCE ALONG OCCLUDED AND WARM FRONTS ALONG WITH
UPR LEVEL Q VECTOR CONVERGENCE PROVIDING FORCING. APCHG UPR LOW
SHOULD ALSO HELP DESTABILIZE AIRMASS... THOUGH CLOUD COVER WILL
PRBLY INHIBIT DESTABILIZATION AT LEAST SOMEWHAT. DEEP LAYER SHEAR
PROGGED AROUND 40KT MAINLY ACROSS SE 1/2 OF CWA SHOULD SUPPORT SVR
STORMS IF SUFFICIENT DESTABILIZATION IS REALIZED. SMALL MBE VECTORS
AND MOIST AIRMASS WITH PWAT NR 1.50 INCHES ALSO SUGGEST POTENTIAL
FOR BACKBUILDING STORMS WITH LOCALLY HEAVY RAINFALL.

SHOWERS/HVY RAIN/SVR THREAT WILL DIMINISH THU NGT AS LOW LIFTS NE
INTO SERN MI AND DIURNAL COOLING AND DVLPG LOW LEVEL CAA STABILIZES
AIRMASS. STILL... PROSPECTS FOR SHOWERS CONTG INTO EVE AND POTENTIAL
FOR SOME LIGHT RAIN IN THE CAA REGIME OVERNIGHT FAVORABLE ENOUGH TO
BUMP UP POPS INTO LIKELY RANGE THU NGT.

LOW WILL MOVE INTO SERN ONTARIO FRIDAY. LOW LEVEL CAA IN ITS WAKE
SHOULD RESULT IN COOLER THAN NORMAL DAY WITH CONSIDERABLE CLOUDS AND
A CHC OF OCNL LINGERING LIGHT RAIN. ANOTHER SHRTWV EXPECTED TO MOVE
INTO THE UPR GRTLKS FRI NGT. CONSIDERABLE DIFFERENCES AMONG MEDIUM
RANGE MODELS ON TIMING/STRENGTH OF THIS FEATURE REMAIN. GFS CONTS TO
BE STRONGER/FASTER WITH THE SYSTEM SUGGESTING CHC OF SHOWERS WITH
THE CDFNT EARLY SAT AND AGAIN AS THE FRONT LIFT BACK NORTH EARLY
SUNDAY WHILE SLOWER/WEAKER ECMWF INDICATES FRONT/FORCING/SHOWERS
WILL REMAIN NW OF OUR CWA. FOR NOW MAINTAINED GOING LOW CHC SHOWERS
IN GRIDS FOR FRI NGT-SAT NGT. IN EITHER CASE IN THE WAKE OF THIS
SYSTEM, SUMMERLIKE UPR RIDGE EXPECTED TO BEGIN BUILDING OVER THE ERN
U.S..  HOW FAST THIS OCCURS AND THE EXACT PLACEMENT OF THE UPR LEVEL
HIGH A MATTER OF CONTENTION BTWN MEDIUM RANGE MODELS BUT GOOD
