RUC CONTINUES TO INDICATE MLCAPE VALUES IN 500-1000 J/KG RANGE WHILE WEAK SFC TROUGH FROM EAST CENTRAL IL NORTH INTO CENTRAL WI SUPPLYING LOW LEVEL CONVERGENCE FOR CONVECTIVE INITIATION. RELATIVELY LOW FREEZING LEVELS AROUND 9.7 KFT ALREADY RESULTING IN SOME 1/2 INCH HAIL IN CRYSTAL LAKE IL...THOUGH CELLS HAVE SINCE WEAKENED. ISOLATED/SCATTERED PULSE STORMS LIKELY TO CONTINUE INTO EVENING HOURS BEFORE LOSS OF DIURNAL INSTABILITY SHUTS THINGS DOWN...WITH THE POTENTIAL FOR THE STRONGEST UPDRAFTS TO PRODUCE SOME PEA TO MARBLE SIZE HAIL AND GUSTY OUTFLOW WINDS. VORT SLIDES OFF TO THE SOUTHEAST OF THE FCST AREA OVERNIGHT TONIGHT...THOUGH NEXT IN A SERIES OF ASSORTED SPEED/VORT MAXIMA DROPS SOUTHWARD DOWN WESTERN SIDE OF DEEPENING UPPER TROUGH OVER EASTERN U.S. WHILE NAM/GFS BOTH INDICATE A LITTLE LOW LEVEL WAA INTO WRN IL LATE...AND EVEN A LITTLE LIGHT QPF IN THE 06-12 UTC TIME FRAME...TSECTS OVER FCST AREA INDICATE SUBSIDENCE WITH LOW LEVEL COOL ADVECTION. SO OTHER THAN EARLY EVENING DIURNAL RW/TRW...EXPECT PARTLY CLOUDY/DRY CONDITIONS LATER TONIGHT. SFC PARCEL TRAJECTORIES SUPPORT GUIDANCE MIN TEMPS GENERALLY IN MID 50S BY SAT MORNING. YET ANOTHER VORT DROPS SOUTH ACROSS THE WESTERN LAKES SATURDAY...WITH THE GFS MAINTAINING A SHARPER MID LEVEL TROUGH THAN THE NAM. LOW LEVELS DOMINATED BY DRY/COOL ADVECTION HOWEVER...WITH BOTH GFS/NAM SOUNDINGS INDICATING A BIT OF A CAPPING WARM BULGE IN THE 700-600 HPA LAYER...SO DESPITE INCREASING VORTICITY ADVECTION DURING AFTN APPEARS INSTABILITY AND LOW LEVEL FOCUS LACKING. AM PLANNING TO CONTINUE DRY FCST AT THIS TIME. LOW LEVEL CAA EXPECTED TO RESULT IN SLIGHTLY COOLER TEMPS NEXT COUPLE OF DAYS...GENERALLY MID/UPPER 70S FOR HIGHS THOUGH COOLER WITH NNE FLOW ALONG/OFF LAKE MICHIGAN. UPPER LOW THEN DRIFTS EAST A BIT ON SUNDAY...ALLOWING SFC RIDGE TO SLIDE INTO AREA. SOME SHEARED VORTICITY CONTINUES TO ROTATE THROUGH BACK SIDE OF DEPARTING CIRCULATION...THOUGH AGAIN COOLER LOW LEVELS RESULT IN RELATIVELY STABLE THERMAL PROFILES. SFC RIDGE THEN SHIFTS EAST ACROSS FCST AREA SUNDAY NIGHT...WITH RETURN SELY FLOW DEVELOPING ON MONDAY. ANOTHER SHORT WAVE PUSHES ACROSS UPPER MIDWEST...WITH MAIN THERMAL/MOISTURE ADVECTION AND FORCING ORIENTED TO OUR NW INTO MN AND UPPER MS VLY. SHOULD BE DRY DAY HERE WITH SOME MODERATION IN TEMPS TO AROUND 80 AS MID LEVEL SHORT WAVE RIDGE OVERHEAD. STILL SOME LAKE COOLING HOWEVER ESPECIALLY IL SHORE AS SFC GRADIENT MORE SE ON WEST SIDE OF DEPARTING HIGH PRESSURE. SOME INDICATION THAT OVERNIGHT CONVECTION TO OUR NORTHWEST MAY SLIDE INTO NRN IL/IND TOWARD TUES MORNING AS LOW LEVEL JET VEERS INTO WRN LAKES. BASED ON THIS WILL MAINTAIN CHC POPS TUES IN GOING FCST. NO BIG CHANGES TO EXTENDED RANGE AT THIS TIME...AS CONSIDERABLE SPREAD IN MODEL SOLUTIONS MID WEEK. ECMWF DEVELOPS CLOSED UPPER LOW OVER WESTERN LAKES WHILE GFS KEEPS LOW WELL TO THE NORTHEAST. HESITANT TO PULL/ADD POPS DAYS 5-7 AT THIS TIME UNTIL A LITTLE MORE CONTINUITY DEVELOPS IN MODEL RUNS. RATZER && .AVIATION DISCUSSION FOR 18Z TAFS... 1245 PM CDT... AGAIN...LITTLE CHANGE FROM THE PREVIOUS SET OF TAFS. SCT CU AND AC HAS DEVELOPED ACROSS THE REGION LATE THIS MORNING AND THE AC SHOULD CONTINUE TO INCREASE IN COVERAGE. ADEQUATE INSTABILITY AND FORCING FROM A SHORT WAVE TROUGH DROPPING THROUGH THE REGION IS TRIGGERING SOME ISOL SHRA AND MAY BECOME STG ENUF FOR A FEW TS. DO NOT EXPECT COVERAGE WIDE ENOUGH TO IMPACT THE TAF SITES...SO HAVE MAINTAINED THE VCSH...AND HAVE ADDED CB TO THE LOW CLOUD GROUP TO INDICATE THE STG VERTICAL GROWTH THAT SOME SHRA MAY EXHIBIT. BASES AND LOW CLOUD COVERAGE SHOULD REMAIN AT VFR LEVELS THROUGH THE AFTERNOON AND EARLY EVENING. APPROACHING SUNSET...THE SHRA POTENTIAL WL DIMINISH AND SKIES SHUD GO SKC BEFORE MIDNIGHT AND REMAIN SO THROUGH LATE MORNING TOMORROW. WITH A NLY PRESSURE GRADIENT AND WEAK LOW LEVEL FLOW...A LAKE BREEZE IS LIKELY...WITH WINDS TURNING NELY AT ORD/MDW/DPA AND NLY AT GYY. WINDS AT RFD SHUD REMAIN REFLECTIVE OF THE SYNOPTIC FLOW PATTERN. OVERNIGHT...EXPECTING SKC/CALM CONDITIONS TO DVLP AFTER LOOSING THE DAYTIME HEATING AND LARGE SCALE SUBSIDENCE COVERS THE REGION.
