NWS Chicago, IL wrote its last area forecast discussion before the first event at Jun 28, 6:28 PM CST, 1 hour 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 728 PM CDT WED JUN 28 2006 .DISCUSSION FOR EVENING UPDATE... 728 PM CDT UPDATED ZFP/GRIDS FOR HIGHER POPS NORTHEAST IL NEXT FEW HOURS. WATER VAPOR INDICATES FAIRLY SHARP VORT/JET STREAK DIGGING THROUGH UPR MS VLY INTO BACK SIDE OF UPPER TROUGH THIS EVENING...WITH PROFILER NETWORK SHOWING 40 KT SPD MAX AT 500 HPA. THUNDERSTORMS OCCURRING ALONG SFC TROUGH/OUTFLOW BOUNDARY ON NOSE OF VORT FEATURE...ALSO LOCATED BENEATH LEFT EXIT OF MID/UPPER LEVEL JET STREAK. INSTABILITY MARGINAL...WITH MODIFIED ACARS SOUNDINGS/RUC SPC MESO GRAPHICS SUGGESTING BETWEEN 500-1000 J/KG SBCAPE. HOWEVER...MID LEVEL FORCING STRONG ENOUGH TO MAINTAIN THREAT OF RW/TRW THROUGH EVENING UNTIL MID LEVEL TROUGH AXIS PASSES THROUGH AROUND 06 UTC. WILL LIKELY SEE WEAKENING WITH LOSS OF SUN AND DERIVED LOW LEVEL INSTABILITY...BUT HAVE BUMPED POPS TO LIKELY FOR NE IL THROUGH MIDNIGHT. RATZER .PREVIOUS DISCUSSION FOR AFTERNOON ZONES/GRIDS... MAIN FORECAST CONCERNS WILL CENTER ON PRECIP CHANCES EARLY THIS EVENING...AND THEN RETURN OF PRECIP CHANCES FRIDAY INTO THE WEEKEND. UPPER LOW CONTINUES TO SLOWLY TRACK EASTWARD THIS AFTERNOON WITH WATER VAPOR IMAGERY SUGGESTING UPPER LEVEL CYCLONIC CIRCULATION CENTERED OVER THE CENTRAL PORTION OF LAKE MICHIGAN AT 19Z. AN ASSOCIATED SURFACE BOUNDARY EXTENDS FROM NORTH CENTRAL INDIANA INTO EAST CENTRAL ILLINOIS. AFTER THIS BOUNDARY PASSAGE SFC DEW PTS HAVE DROPPED OFF INTO THE LOWER AND MID 50S ACROSS MUCH OF NORTHERN ILLINOIS WHICH HAVE LOWERED 100 MB MIXED LAYER CAPES BACK INTO THE 500 J/KG RANGE. RATHER EXTENSIVE CU FIELD FROM SOUTHERN WISCONSIN WILL CONTINUE TO MOVE/DEVELOP SOUTHWARD INTO NORTHERN ILLINOIS LATE THIS AFTERNOON AND EARLY THIS EVENING BUT REGIONAL RADAR MOSAICS INDICATING MAIN AREA OF SHOWERS/THUNDERSTORMS ACROSS NORTHEAST WISCONSIN. A COUPLE OF FORCING MECHANISMS LIKELY RESPONSIBLE FOR THIS AREA OF PRECIP. SOME DPVA IS STILL LIKELY PLAYING A ROLE ACROSS NORTHEAST WISCONSIN GIVEN STRONG UPPER CIRCULATION NOTED ON WATER VAPOR IMAGERY AND IN ADDITION...ANOTHER VORT MAX/UPPER JET STREAK CONTINUES TO TRACK THROUGH WESTERN WISCONSIN. THIS JET STREAK WILL APPROACH INTO NORTHERN ILLINOIS THIS EVENING BUT AM NOT OVERLY ENTHUSIASTIC ABOUT THE MAGNITUDE OF FORCING ACROSS NRN ILLINOIS THIS EVENING. INSTABILITY IS ALSO MARGINAL GIVEN THE DRIER LOW LEVEL AIR ACROSS NORTHERN PORTIONS OF CWA...SO AT THIS TIME FEEL THAT 30 POPS ARE APPROPRIATE. NOT MUCH EVIDENCE OF ANY LAKE BREEZE BOUNDARY TO THIS POINT...BUT IF LAKE BOUNDARY CAN DEVELOP OVER THE NEXT FEW HOURS THIS MAY PROVIDE SOME FOCUS FOR LATE AFTERNOON CONVECTION NEAR THE LAKE MICHIGAN SHORE. SKIES WILL CLEAR LATER THIS EVENING WITH LOSS OF DIURNAL INSTABILITY WHICH SHOULD SET UP A QUIET NIGHT WITH SFC HIGH BUILDING IN. MAY SEE SOME LIGHT FOG DEVELOP OVERNIGHT GIVEN LIGHT WIND FIELD/CLEAR SKIES BUT NOT EXPECTING THIS TO AMOUNT TO ANYTHING SIGNIFICANT SO WILL NOT MENTION IT IN THE ZONE FORECAST AT THIS TIME. ON THURSDAY...HIGH WILL BECOME CENTERED ACROSS NORTHERN ILLINOIS WITH POTENTIAL FOR LAKE BREEZE SETTING UP IN THE AFTERNOON GIVEN ABUNDANT SUNSHINE AND WEAK WINDS. FORECAST SOUNDINGS STILL SUGGESTING MID LEVEL SUBSIDENCE INVERSION DEVELOPING ON THURSDAY AND JUST EXPECTING FEW-SCT FLAT AFTERNOON CU DEVELOPING TOMORROW UNDER THE INFLUENCE OF THIS SUBSIDENCE INVERSION. BY THURSDAY NIGHT WARM FRONTAL BOUNDARY IS EXPECTED TO BECOME MORE DEFINED FROM THE CENTRAL PLAINS INTO CENTRAL MISSOURI AS NEXT SHORT WAVE BEGINS TO DAMPEN CENTRAL CONUS UPPER RIDGE. EXTENDED PERIOD OF ISENTROPIC LIFT THEN IN STORE FOR LATE THURSDAY INTO FRIDAY AS HIGH DEPARTS BUT MOISTURE APPEARS TO BE LACKING UNTIL POSSIBLY FRIDAY NIGHT. DID NOT CHANGE INHERITED POPS MUCH AT ALL FOR THIS PERIOD AND WILL MAINTAIN LOW CHANCE POPS FRIDAY NIGHT INTO SATURDAY AS WARM FRONT LIFTS NORTHWARD WITH MORE IMPRESSIVE LOW LEVEL MOISTURE POOLING ALONG THE BOUNDARY. FORECAST CONFIDENCE IS RATHER LOW FOR THE WEEKEND IN TERMS OF TIMING PRECIP CHANCES...ALTHOUGH STILL APPEARS AS THOUGH WARMER TEMPS ARE STILL A SAFE BET WITH BROAD WEST/SOUTHWEST LOW LEVEL FLOW SETTING UP AS SEVERAL SHORT WAVES RIDE ACROSS THE NORTHERN TIER OF CONUS. WRF/GFS/ECMWF NOT IN GOOD AGREEMENT REGARDING EVOLUTION OF AMPLIFIED NORTHERN STREAM FOR THE WEEKEND...SO HAVE OPTED FOR CONSISTENCY IN GOING WITH PRIMARILY A GFS SOLUTION. LOW LEVEL BOUNDARY WILL SLOWLY SAG INTO THE SOUTHERN GREAT LAKES THROUGH EARLY NEXT WEEK SO HAD TO MAINTAIN BROADBRUSH LOW CHANCE POPS FOR THE WEEKEND INTO MONDAY GIVEN TIMING UNCERTAINTIES...BUT THINGS SHOULD DRY OUT LATE MONDAY INTO TUESDAY. NDM && .AVIATION... 00Z TAFS...LINE OF SHOWERS AND TS MOVING SOUTHEAST ACROSS SOUTHERN WI THIS EVENING. PRECIP IS ASSOCIATED WITH A SHORTWAVE MOVING ACROSS THE LAKES REGION. EXPECT SOME WEAKENING BEFORE ARRIVING AT THE TERMINALS BUT EXPECT COVERAGE/INTENSITY TO SUPPORT TEMPO SHOWERS THRU LATE EVENING. HAVE NOT INCLUDED TS BUT THIS WILL NEED TO BE MONITORED AS ACTIVITY HEADS SOUTH. MVFR CIGS/VIS POSSIBLE WITH THE HEAVIER SHOWERS AND POSSIBLY BRIEF IFR. WNW WINDS 10-15KTS WILL DIMINISH WITH SUNSET. HOWEVER...LAKE BREEZE ACROSS SE WI NOW PUSHING SOUTHWEST ACROSS LAKE COUNTY WITH WINDS AT UGN TURNING ENE. THIS LAKE BREEZE SHOULD CONTINUE PUSHING SOUTHWEST AS PREVAILING WESTERLY WINDS DIMINISH. THUS WINDS WILL TURN NE OR ENE DURING THE EVENING HRS. PRECIP TO BE SOUTH OF THE TERMINALS OR DISSIPATED BY MIDNIGHT. LIGHT WINDS OVERNIGHT INTO THURSDAY MORNING WITH A LAKE BREEZE BY LATE THURS MORNING/EARLY THURS AFTERNOON. && .LOT WATCHES/WARNINGS/ADVISORIES... .IL...NONE. .IN...NONE. .LM...NONE. &&
