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..
