NWS Marquette, MI wrote its last area forecast discussion before the first event at Aug 22, 7:05 PM EST, 2 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 805 PM EDT FRI AUG 22 2014 .SHORT TERM...(THIS EVENING THROUGH SATURDAY) ISSUED AT 252 PM EDT FRI AUG 22 2014 ...STAYING HUMID BUT ONLY ISOLD SHOWERS/THUNDERSTORMS... WV LOOP AND 12Z H7-H5 RAOBS SHOW UPPER MISSISSIPPI RIVER VALLEY INTO THE WESTERN GREAT LAKES IS WITHIN WEST/NORTHWEST FLOW ALOFT BTWN TROUGH OVER NORTHERN ROCKIES AND RIDGE CENTERED OVER SOUTHERN UNITED STATES. PRIMARY SFC FRONT IS ORIENTED FM WESTERN KS ACROSS IA AND NORTHERN ILLINOIS TO NORTHERN OHIO. AIRMASS SOUTH OF THE FRONT MORE OPPRESSIVELY HUMID WITH DWPNTS WELL INTO THE 70S. DWPNTS NORTH OF THE FRONT...INCLUDING INTO THE UPR GREAT LAKES ARE STILL HUMID WITH MAINLY 60S SEEN. MOST OF THE SHRA/TSRA ARE ONGOING ALONG THE FRONT CLOSER TO GREATER INSTABILITY. RADAR OVER THE UPR GREAT LAKES DOES SHOW ISOLD SHRA WITH SOMEWHAT BETTER COVERAGE OVER NORTHERN WI AND INTO CNTRL UPR MICHIGAN CLOSER TO A WEAK SFC-H85 WAVE AND ALSO WHERE H85-H7 THETA-E RIDGE IS MORE PRONOUNCED. VERY LITTLE IN WAY OF SHORTWAVES AND LARGE SCALE LIFT ON TOP OF THE RIDGE...BUT THERE IS A STRONGER WAVE/COLDER CLOUD TOPS SEEN OVER THE DAKOTAS. REGIONAL RADAR SHOWS SHRA/ISOLD TSRA WITH THE SHORTWAVE FM NE INTO DAKOTAS AND NORTHERN MN. REST OF AFTN INTO EARLY EVENING SHOULD REMAIN MOSTLY CLOUDY. SHRA AND PERHAPS A TSRA MAINLY WEST HALF...ESPECIALLY CLOSER TO WI BORDER...MOSTLY DUE TO THE PROXIMITY OF THE H85-H7 THETA-E RIDGE AND 1-6KM MUCAPES UP TO 200J/KG. LIMITED FORCING WILL RESULT IN ONLY ISOLD COVERAGE TO ANY SHRA...THOUGH ANY SHRA COULD PRODUCE HEAVY DOWNPOURS GIVEN PWATS OVER 175 PCT OF NORMAL. TEMPS IN THE 70S WITH DWPNTS IN THE 60S AND NOT MUCH WIND WILL KEEP CONDITIONS ON THE HUMID SIDE. LATER THIS EVENING AND ON INTO THE OVERNIGHT HOURS...SHORTWAVE OVER DAKOTAS MOVES EAST...BUT IT WILL PROBABLY WEAKEN WHILE PUSHING INTO THE BUILDING RIDGE. ALSO...EXPECT H85-H7 THETA-E RIDGE TO LIFT MORE ACROSS UPR MICHIGAN WHILE ALSO WEAKENING. SFC WAVE OVER WI WILL ALSO BE FILLING...WITH HIGHER PRESSURE DEVELOPING OVER UPR LAKES. MAIN SHORT TERM MODEL DIFFERENCE DEALS WITH HOW FAR EAST THETA-E RIDGE AXIS PROGRESSES AND THUS HOW FAR EAST SMALL CHANCES FOR SHRA WILL BE. EVEN THOUGH COVERAGE WILL REMAIN LIMITED...HEAVY DOWNPOURS...WILL STILL BE POSSIBLE WITH STEERING WINDS LESS THAN 10 KTS AND PWATS 175-200PCT OF NORMAL/K INDEX VALUES AROUND 35. TSRA CHANCES MEAGER THOUGH AS WHATEVER MUCAPE IS AROUND EARLY THIS EVENING IS NIL AFT 03Z. LOW-LEVEL INVERSION COULD RESULT IN FOG FORMING LATER TONIGHT...BUT SINCE CLOUD DEPTH REMAINS FAIRLY DEEP...THROUGH AROUND H8...SHOULD BE MORE OF A STRATUS/1-3SM VSBY SETUP INSTEAD OF WIDESPREAD DENSE FOG. INTO SATURDAY...H85-H7 THETA-E RIDGE SEEMS TO REFOCUS OVER MAINLY WESTERN CWA BY LATE MORNING. NEUTRAL TO ANTICYCLONIC LOW-LEVEL FLOW WILL BE IN PLACE AS THE SFC LOW WILL HAVE DISSIPATED. IF THERE IS ANY POTENTIAL OF SHRA ON SATURDAY AFTERNOON...EXPECT IT TO BE WITHIN THAT THETA-E RIDGE AXIS AND ALSO DUE TO LIFT AHEAD OF SHORTWAVE MODELS SHOW EMERGING OUT OF NEB THIS AFTN. MLCAPES UP TO 200J/KG AND H8-H7 WINDS FM THE SOUTH COULD ALSO ALLOW A TSRA TO AFFECT FAR WEST UPR MICHIGAN IN THE AFTN. ELSEWHERE OVER CNTRL AND EAST CWA...EXPECT MOSTLY CLOUDY SKIES TO GRADUALLY THIN OUT WITH PROBABLY MORE SUNSHINE SEEN THAN THE LAST COUPLE DAYS. MORE SUNSHINE COMBINED WITH H85 TEMPS AROUND 15C ON AVERAGE SHOULD RESULT IN TEMPS IN THE MID 70S TO AROUND 80. LOWEST READINGS WILL OCCUR OVER FAR WEST WITH MORE CLOUD COVER EXPECTED THERE. DWPNTS IF ANYTHING MAY BE SLIGHTLY HIGHER IN MID-UPR 60S...SO IT WILL CONTINUE TO BE HUMID. .LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY) ISSUED AT 347 PM EDT FRI AUG 22 2014 LOOKS LIKE A PERIOD OF WARMER...MORE HUMID WX TYPICAL OF MID SUMMER WL DOMINATE INTO EARLY NEXT WEEK AS A HI AMPLITUDE UPR RDG BLDS INTO THE GREAT LKS DOWNSTREAM OF DEEPENING TROF ACRS THE W. BEST CHC OF PCPN APPEARS WL BE ON SUN NGT/MON AS A SHRTWV RIDING OVER THE RDG DRAGS A COLD FNT INTO THE UPR LKS AND AGAIN ON TUE INTO WED AS ANOTHER SHRTWV APRCHS FM THE W. ALTHOUGH THE LONGER RANGE GUIDANCE INDICATES A MORE ZONAL FLOW WL DVLP NEXT WEEK...THERE IS POOR EXTENDED MODEL AGREEMENT AND RUN-TO-RUN CONSISTENCY ON THE DETAILS OF THIS EVOLUTION. SAT NGT/SUN...PERSISTENT UPR RDG AXIS STRETCHING FM THE SCENTRAL CONUS THRU THE GREAT LKS TO JAMES BAY WL PREVAIL THRU THIS TIME AND SUPPORT A SFC-H85 HI CENTERED NEAR MONTREAL. AT THE SAME TIME...A SHRTWV WL BE LIFTING NEWD FM THE CENTRAL ROCKIES INTO THE NRN PLAINS...WITH ACCOMPANYING SFC LO FCST TO MOVE NEAR LK WINNIPEG BY 00Z MON. ALTHOUGH THE SLY FLOW IN THE WARM SECTOR BTWN THIS LO AND THE HI TO THE E WL ADVECT WARMER...MORE HUMID AIR INTO THE UPR LKS WITH H85 TEMPS FCST AS HI AS ARND 20-23C...ABSENCE OF HGT FALLS SO FAR E OF THE SHRTWV TRACK AND H85 LLJ/HIER THETA E AXIS STILL IN MN AT 12Z SUN SHOULD MAINTAIN DRY WX OVER UPR MI. CURRENT FCST HAS SOME SCHC POPS EXTENDING AS FAR E AS THE WRN LAND CWA DURING THIS TIME... CONSISTENT WITH THE FCST E EDGE OF THE DEEP LYR QVECTOR CNVGC ACCOMPANYING THE DYNAMIC FORCING/MSTR ADVCTN TO THE W. HUMID AIRMASS WL SUPPORT PATCHY FOG DURING THE DIURNAL COOLING ON SAT NGT INTO SUN MRNG. SUN NGT THRU MON NGT...AS THE SHRTWV/SFC LO RIDE NEWD AND INTO NW ONTARIO...ATTENDANT COLD FNT IS FCST TO MOVE INTO WRN LK SUP SUN NGT AND THEN INTO UPR MI ON MON. THE 12Z GFS HAS SLOWED DOWN THE PROGRESSION OF THIS FNT WITH A MORE AMPLIFIED RDG/SW FLOW ALF PARALLEL TO THE FNT AND INDICATES THE FNT WL STALL OVER THE CWA ON MON NGNT. ON THE OTHER HAND...THE 12Z CNDN/ECMWF MODELS REMAIN CONSISTENT WITH THEIR EARLIER RUNS SHOWING THE FNT MOVING THRU THE CWA BY 00Z TUE. AS FOR POPS...WARM CONVEYOR BELT MSTR RIBBON/AXIS OF DEEP LYR QVECTOR CNVGC IS FCST TO MIGRATE SLOWLY E ACRS THE CWA WITH THE FNT. THE 12Z CNDN/ECMWF SHOW THE MOST AGGRESSIVE MID LVL DRYING/ DEEP LYR QVECTOR DVGC ON MON AFTN...AND EVEN THE SLOWER GFS INDICATES SOME MID LVL DRYING DURING THE AFTN. WL GO NO HIER THAN CHC POPS GIVEN THE TRACK OF THE SHRTWV/SFC LO/MOST VIGOROUS DPVA AND DEEP LYR FORCING SO FAR TO THE N THAT CONTRIBUTES TO 12HR H5 FALLS NO MORE THAN 30-40M DURING THIS TIME EVEN BY THE MOST AGGRESSIVE CNDN MODEL. GIVEN THE HI AMPLITUDE RDG...SUSPECT THE SLOWER GFS IS ON THE RIGHT TRACK...SO SLOWED DOWN THE FROPA TIMING/DRYING TREND... WITH HIER POPS/LESS COOLING ON MON NGT. EXPECT THE HIEST CHC POPS OVER THE E HALF ON MON AFTN AS THE ARRIVAL OF THE FNT WL COINCIDE WITH PEAK DIURNAL HEATING. EXPECT TEMPS TO RUN WELL ABV NORMAL ON SUN NGT THRU MON NGT. SUN NGT SHOULD BE PARTICULARY WARM RELATIVE TO AVG WITH A STEADY SSW FLOW AND MOISTER ENVIRONMENT WITH FCST PWAT AS HI AS 1.75 INCHES /175-200 PCT OF NORMAL/. EXTENDED...THE UPR FLOW IS FCST BY MOST OF THE LONGER RANGE MODEL GUIDANCE/ENSEMBLES TO TURN MORE ZONAL ALONG THE CNDN BORDER FOLLOWING THE PASSAGE OF THE SHRTWV THRU NW ONTARIO/UPR LKS FROPA ON MON/MON NGT. NOT SURPRISINGLY...THERE HAS BEEN POOR MODEL AGREEMENT AND RUN-TO-RUN CONSISTENCY REGARDING THE DETAILS OF THE FCST FOR NEXT WEEK. FOR INSTANCE...RECENT GFS RUNS HAVE SHOWN A MORE AMPLIFIED SHRTWV TRACKING THRU THIS FLOW AND BRINGING BETTER PCPN CHCS TO THE AREA FM LATE TUE INTO AT LEAST THU...BUT THE 12Z GFS HAS BACKED AWAY FM THIS A BIT. ON THE OTHER HAND...THE 00Z CNDN MODEL FCST ONLY A WEAK SHRTWV PASSING THRU THE UPR LKS ON WED WITH ALL PCPN REMAINING S OF THE FA. NOW THE 12Z MODEL GENERATES A FCST SIMILAR TO THE ONE SHOWN BY THE MORE VIGOROUS 06Z GFS. GIVEN THE POOR CONTINUITY AND CONSISTENCY...WL RELY ON MODEL CONSENSUS FOR THE EXTENDED FCST. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SATURDAY EVENING) ISSUED AT 752 PM EDT FRI AUG 22 2014 STRENGTHENING INVERSION TONIGHT AND PLENTY OF MOISTURE BENEATH THE INVERSION WILL ALLOW FOR MORE LOW STRATUS AND FOG TO DEVELOP LATE TONIGHT INTO SATURDAY MORNING. LIFR CONDITIONS HAVE ALREADY WORKED INTO KIWD EARLY THIS EVENING AND WOULD EXPECT THESE TO PERSIST INTO SAT MORNING. AT BOTH KCMX AND KSAW...EXPECT CONDITIONS TO LOWER FROM MVFR THIS EVENING TO IFR OVERNIGHT. ISOLD SHRA WILL BE AROUND THE AREA THIS EVENING BUT SHOULD ONLY AFFECT KSAW BRIEFLY SO INCLUDED VCSH MENTION IN TAF. WITH DIURNAL HEATING EXPECT SLOW IMPROVEMENT TO MVFR CONDITIONS AT BOTH KIWD AND KCMX AND TO VFR AT KSAW BY SAT AFTERNOON. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 252 PM EDT FRI AUG 22 2014 RELATIVELY WEAK PRESSURE GRADIENT WILL KEEP WINDS BELOW 20 KTS INTO SATURDAY.

SOUTHEAST WIND GUSTS TO 25 KTS EXPECTED SUNDAY AFTN AND EVENING AHEAD OF THE LOW...THEN ON MONDAY BEHIND A COLD FRONT...EXPECT WEST TO SOUTHWEST WINDS GUSTING TO 25 KTS.
