NWS Marquette, MI wrote its last area forecast discussion before the first event at Jun 19, 5:40 AM CST, 1 hour 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 740 AM EDT TUE JUN 19 2012 .SYNOPSIS... ISSUED AT 521 AM EDT TUE JUN 19 2012 WV IMAGERY AND RUC ANALYSIS INDICATED A MID/UPPER LEVEL TROUGH OVER THE NW CONUS AND A RIDGE OVER THE CNTRL MS VALLEY RESULTING IN WSW FLOW FROM THE NRN PLAINS INTO THE NRN GREAT LAKES. EXPECT THE PATTERN TO AMPLIFY AS A SHORTWAVE TROUGH OFF THE PAC NW DIGS TO THE SE AND A SHRTWV OVER MT LIFTS INTO CANADA. AT THE SFC...LOW PRES WAS LOCATED OVER N CNTRL NEB WITH A WARM FRONT EXTENDING INTO SRN MN. AN MCS FROM NE SOUTH DAKOTA INTO SRN MN AND FAR WRN WI WAS FUELED BY A 40-50 KT LLJ PROVIDING PLENTIFUL MOISTURE INFLOW INTO THE 850 MB FRONTAL ZONE. WITH LEFTOVER LOW LEVEL MOISTURE...LIGHT WINDS AND DRYING MID LEVELS...AREA OF FOG HAVE DEVELOPED OVER MUCH OF THE CWA...EXCEPT WHERE MORE DOWNSLOPE FLOW PREVAILED NEAR LAKE SUPERIOR. && .SHORT TERM...(TODAY) ISSUED AT 521 AM EDT TUE JUN 19 2012 TODAY...THE FOG WILL DIMINISH THIS MORNING AS HIGHER CLOUDS MOVE IN AND AS DAYTIME HEATING BEGINS. SATELLITE AND RADAR TRENDS ALONG WITH 850 MB MOISTURE TRANSPORT PROGS SUGGEST THAT THE STRONGEST CONVECTION SHOULD SLIDE MAINLY TO THE EAST INTO CNTRL AND NRN WI. HOWEVER...AS THE WARM FRONT GRADUALLY LIFTS TO THE NORTH...SOME SHRA AND ISOLD TSRA MAY ALSO SPREAD INTO W AND SOUTHERN PORTIONS OF UPPER MI. A FEW SHRA/TSRA MAY ALSO BE POSSIBLE OVER THE NORTH AND EAST BY LATE MORNING AND THIS AFTERNOON GIVEN THE NORTHWARD MOVEMENT OF THE SFC-850 MB FRONT. MUCAPE VALUES IN THE 1K-2K J/KG RANGE COULD SUPPORT SOME STRONGER TSRA WITH SMALL HAIL IF THE CONVECTION AS THE CONVECTION OVER WI WEAKENS AND GREATER MOISTURE TRANSPORT OCCURS INTO UPPER MI. INCREASING CLOUDS WILL KEEP TEMPS FROM CLIMBING AS FAST THIS MORNING INTO EARLY AFTERNOON...BUT SUNSHINE THROUGH THINNING CLOUDS FROM S TO N BY MID TO LATE AFTERNOON SHOULD ALLOW INLAND TEMPS TO CLIMB INTO THE MID 80S. THE BEST CHANCE FOR ANY SEVERE WEATHER WOULD BE OVER THE WEST BY LATE THIS AFTERNOON OR EARLY EVENING AS CONVECTION DEVELOPING OVER MN OR NRN WI DURING PERIOD OF PEAK HEATING/INSTABILITY SPREADS INTO THE AREA. 0-6KM BULK SHEAR TO 50 KT WOULD SUPPORT ORGANIZED CONVECTION WITH CONDITIONAL THREAT FOR DAMAGING WINDS OR LARGE HAIL AND POSSIBLY A TORNADO. TONIGHT...WITH THE WARM FRONT LIFTING TO THE NORTH AND WEST OF THE AREA...CAPPING WILL LIMIT SHRA/TSRA CHANCES OVER MOST OF THE CWA. THE BEST CHANCE FOR PCPN WILL BE OVER WRN LAKE SUPERIOR AND THE ADJOINING PORTIONS OF THE CWA WHICH WILL BE IN CLOSEST PROXIMITY TO THE 850 MB FRONT AND FORCING FROM ANY WEAK SHORTWAVES LIFTING NE FROM THE PLAINS. TEMPS WILL AGAIN REMAIN WELL ABOVE NORMAL...WITH MIN READINGS IN THE MID AND UPPER 60S. .LONG TERM...(TONIGHT THROUGH MONDAY) ISSUED AT 502 AM EDT TUE JUN 19 2012 WEDNESDAY THROUGH WEDNESDAY NIGHT... EXPECT INCREASED SW FLOW WEDNESDAY...AS THE 500MB LOW NEARS FROM LAKE WINNIPEG. THE SFC LOW SHOULD BE OVER MN/S ONTARIO/W LAKE SUPERIOR BY DAYBREAK WEDNESDAY. THERE REMAINS SIGNIFICANT DIFFERENCES ON THE TRACK OF THIS LOW WEDNESDAY INTO WEDNESDAY NIGHT...WITH THE NAM/GFS/SREF HOLDING ONTO A MORE NORTHERN SOLUTION AND THE ECMWF/CANADIAN HOVERING JUST NORTH OF LAKE SUPERIOR BY 00Z THURSDAY. THE 00Z RUNS HAVE COME INTO SLIGHTLY BETTER AGREEMENT...WITH THE 06Z NAM NOW BEING THE NORTHERN OUTLIER. PRECIPITATION AMOUNTS VARY FROM AROUND A TENTH OF AN INCH OR LESS /ECMWF WITH MUCH OF THE ENERGY SLIDING INTO CANADA/...TO A HALF IN INCH TO AROUND AN INCH /GFS WITH A MORE DISTINCT TROUGH/. WILL HOLD OFF ON ANY GREAT ASSUMPTIONS YET...ALTHOUGH MODERATE TO HEAVY RAIN WILL BE POSSIBLE SOMEWHERE ALONG THE COLD FRONT. WHILE INITIALLY ABOUT 3HRS SLOWER THAN THE GFS...THE FRONT LOOKS TO SPEED UP OFF THE ECMWF...SO THAT THEY ARE CONSISTENT WITH THE FEATURE BEING E OF UPPER MI BY 12Z THURSDAY. A FEW STRONG STORMS WILL REMAIN POSSIBLE...MAINLY CENTRAL AND E...WITH MLCAPE VALUES OVER 1K J/KG...MLLAPSE RATES 6-8C/CM /HIGHEST SOUTH CENTRAL BY EARLY AFTERNOON/. THURSDAY THROUGH FRIDAY... THE 500MB LOW WILL EJECT NE AND RESIDE OVER N ONTARIO/HUDSON BAY BY THURSDAY MORNING. THE ROTATING LOW TO OUR NORTH WILL KEEP A TROUGH ACROSS THE UPPER GREAT LAKES THURSDAY THROUGH THURSDAY NIGHT...AS HIGH PRESSURE BUILDS IN AT THE SFC. CONTINUED THE TREND OF LOWERING DEW POINTS FOR THURSDAY. MIXED DEW POINTS IN THE 30S /POSSIBLY UP TO 800MB/ COULD SPELL RH VALUES NEAR 20 TO 30 PERCENT. HIGHS WILL BE IN THE 70S...WITH W-NW WINDS GUSTING NEAR 20KTS OR GREATER OVER MUCH OF THE AREA WITH THE HIGHEST MOSTLY LIKELY ACROSS THE KEWEENAW PENINSULA. THE COOLEST AIR AT 850MB WILL BE FROM 00-18Z FRIDAY...TRANSLATING TO HIGHS IN THE 70S ONCE AGAIN...COOLEST NEAR THE GREAT LAKES AS AFTERNOON LAKE BREEZES SLIDE IN. SATURDAY THROUGH MONDAY... THE SIZABLE RIDGE OVER THE INTERIOR WEST WILL BRIEFLY PUSH A RIDGE THROUGH UPPER MI THROUGH SATURDAY...BEFORE ANOTHER TROUGH ROTATES IN FROM THE HUDSON BAY LOW SATURDAY NIGHT THROUGH SUNDAY. NW FLOW WILL REMAIN AT 500MB THROUGH MONDAY. WITH LIGHT WINDS OVERHEAD...LAKE BREEZES SHOULD BE THE BE THE RULE AGAIN SATURDAY AFTERNOON. THE NEXT CHANCE OF PRECIPITATION...ALTHOUGH MAINLY OVER N/C WI...WILL BE SATURDAY...ASSISTED BY AN UPPER LVL WAVE AS UPPER MI BECOMES STUCK BETWEEN THE SFC LOW OVER SD/NE AND ANOTHER OVER ONTARIO. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING) ISSUED AT 739 AM EDT TUE JUN 19 2012 EXPECT A WARM FNT MOVING S-N THROUGH THE AREA TO BRING SOME SCT -SHRA BUT CONDITIONS SHOULD BE VFR. THE ONE EXCEPTION MAY BE AT CMX WITH UPSLOPE ESE WIND AHEAD OF THE SFC WARM FNT. INCLUDED JUST A MENTION OF SCT LO CLDS ATTM TO ACCOUNT FOR THIS POTENTIAL. ONCE THE WARM FNT SHIFTS TO THE N OF UPR MI TNGT...EXPECT A RETURN OF DRY WX/VFR CONDITIONS AND SOME LLWS UNDER STRENGTHENING SW LLJ AT SAW/CMX...WHICH WL BE LESS EXPOSED TO THE SSW FLOW THAN IWD. && .MARINE...(FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 502 AM EDT TUE JUN 19 2012 A TROUGH OF LOW PRESSURE EXTENDING FROM W CENTRAL QUEBEC...THROUGH LS...TO SD WILL NOT MOVE MUCH. THE SD LOW WILL PUSH ACROSS W LS AND MN THIS EVENING...BEFORE MAKING IT TO N CENTRAL ONTARIO WEDNESDAY EVENING...WHILE DRAGGING A TROUGH/COLD FRONT ACROSS THE UPPER GREAT LAKES WEDNESDAY AFTERNOON INTO WEDNESDAY NIGHT. HIGH PRESSURE WILL THEN BUILD ACROSS THE UPPER GREAT LAKES THURSDAY THROUGH FRIDAY...PUTTING AN END TO ANY LINGERING FOG ACROSS E LS. EXPECT THE HIGH TO SLIDE TO THE LOWER GREAT LAKES FRIDAY NIGHT INTO SATURDAY...WITH AN ADDITIONAL HIGH SLIDING INTO THE AREA FROM S CENTRAL CANADA. && .MQT WATCHES/WARNINGS/ADVISORIES...
