NWS Marquette, MI wrote its last area forecast discussion before the first event at Jun 6, 12:45 PM EST, 15 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MARQUETTE MI 145 PM EDT FRI JUN 6 2008 UPDATED AVIATION SECTION FOR 18Z TAFS .UPDATE... INITIAL BATCH OF SHOWERS AND ISOLD THUNDERSTORMS CAME THROUGH THIS MORNING WITHOUT MUCH FANFARE. CONCERNED THAT 50 KT AT 1KFT ON GRB 12Z SOUNDING AND MQT VWP COULD MIX DOWN BUT STABLE LAYER AND LACK OF REAL STRONG CORES WITH ANY CELLS PROHIBITED THIS FM OCCURRING. VIS SATELLITE AND SFC OBS INDICATE IMPROVEMENT IN LWR VIS/FOG AND LOW CLOUDS. CLEARING SLOT PUSHING INTO SCNTRL UPR MI ATTM SHOULD WORK QUICKLY TOWARD LAKE SUPERIOR BY EARLY AFTN. ADJUSTED POPS LOWER FOR NEXT FEW HOURS. TEMPS FM ECNTRL WI INTO NRN LWR MI HAVE SKYROCKETED THIS MORNING WITH H85 OF +20C. NUMEROUS SITES IN NRN LWR WERE AT 80 AS OF 10 AM. H85 TEMPS A BIT COOLER OVR CNTRL WI...BUT WITH SUNSHINE NEXT FEW HOURS...TEMPS INTO LWR 80S A GOOD BET OVER WEST HALF OF CWA...AWAY FM EAST FLOW OVR KEWEENAW. LATEST SAT SHOWS THIS IS EVADING NOW AS WELL THOUGH SINCE WINDS JUST OFF SFC ARE STRONG FM THE SOUTH. KEYING IN ON SHORTWAVE TROUGH/SFC COLD FRONT NOW PUSHING INTO FAR SE MN FOR CONVECTIVE CHANCES THIS AFTN. GRB SOUNDING LIKELY NOT REPRESENTATIVE WITH SUCH WARM H85 TEMPS. INSTEAD USED MPX AND MODIFYING THIS FOR 80/62 GAVE SBCAPE UP TO 700J/KG WITH CIN BTWN 50 AND 75 J/KG. IF TD CAN STAY UP IN THE MID 60S...THEN THE CAPE VALUES WERE BTWN 1000-1500 J/KG WITH MINIMAL NEG AREA. ML CAPES NEAR 1000 ADVECTING NORTH AHEAD OF THE FRONT SEEM GOOD AS ML DEWPOINTS ARE INTO THE LWR 60S...WHICH IS WHAT THE OBS POINT TO IN NW WI. CURRENT THINKING IS AS SHORTWAVE TROUGH/SFC COLD FRONT MOVES INTO WCNTRL WI BY 18Z...CONVECTION DEVELOPING OVR SE MN SHOULD EXPAND AND BEGIN TO TRANSLATE NORTHEAST. BASED ON 925MB-850MB WINDS OF 50KT ANY CONVECTION WILL TRANSLATE RATHER QUICKLY. 0-6KM BULK SHEAR LEVELS OFF AROUND 40KT BY LATE AFTN...WHILE 0-2.5KM SHEAR IS AROUND 20KT. THIS WOULD SEEM TO FAVOR STRONG...POTENTIALLY DAMAGING WINDS TO 50 KNOTS/60 MPH WITH ANY STORMS/LINE SEGMENTS THAT CAN BECOME ORIENTED PERPENDICULAR TO THE 210 DEGREE STORM MOTION. MINI-LOW TOPPED SUPERCELLS ALSO MAY OCCUR WITH A STILL A SLIGHT POTENTIAL OF A TORNADO...ESPECIALLY IF THERE CAN BE SOME LOCALIZED BACKING OF NEAR SFC WINDS. WINDS WILL BE STRONG IN ANY EVENT WITH STRONG WINDS JUST OFF SFC. WHERE MIXING IS OCCURRING CNTRL/ERN WI...WINDS ARE ALREADY GUSTING AT OR NEAR ADVY. SINCE WE ARE GOING TO SEE SOME SUN INTO EARLY AFTN...WIND ADVY SHOULD WORK OUT FINE. && .DISCUSSION... ...MAIN FORECAST CONCERN IS STRONG GRADIENT WINDS TODAY AND SEVERE POTENTIAL FOR THIS AFTERNOON AND TOMORROW AFTN/EVENING... FOR THIS MORNING...HEAVIEST PRECIPITATION LOOKS TO REMAIN OVER THE FAR WESTERN AREAS OF LAKE SUPERIOR. THIS LINES UP WELL WITH THE BEST DYNAMICS LOCATED ALONG THE WARM FRONT AND NORTH OF THE MAIN LOW. MODIFIED WEATHER WORDING FOR LIKELY SHOWERS AND ONLY A CHANCE FOR THUNDERSTORMS ACROSS THE WEST HALF WITH JUST A CHANCE ACROSS THE EAST. DIDN/T MAKE ANY BIG CHANGES TO THE WEATHER GRIDS FOR THIS AFTERNOON...LEFT THE GENERAL IDEA FROM INHERITED FCST WHICH IS HIGHER POPS ACROSS THE WEST...HOWEVER DID MOVE HIGHER POPS A BIT FURTHER EAST. ANY STORMS THAT WOULD DEVELOP HAVE THE POTENTIAL TO GENERATE STRONG AND PERHAPS DAMAGING WINDS. SOUNDINGS ACROSS THE AREA SHOW INVERTED V PROFILE AND ARE WELL MIXED TO 800MB. IN ADDITION...CONVECTIVE TEMPS. ACROSS THE WEST HALF OF UPPER MICHIGAN ARE ONLY IN THE MID 70S WHICH SHOULDN/T BE HARD TO REACH TODAY. STILL THINK CAP MAY BE TOO STRONG TO OVERCOME ACROSS THE EAST HALF...MAINLY EAST OF A LINE FROM MARQUETTE TO MENOMINEE. OVERNIGHT THE WARM FRONT WILL HAVE MOVED WELL NORTH OF LAKE SUPERIOR...STRONG SOUTHWESTERLY FLOW WILL ALLOW FOR MID LEVEL DRYING...THIS WARRANTED A REDUCTION IN POPS OVERNIGHT. ALSO INCREASED MIN TEMPS IN DOWNSLOPE AREAS...ONT...BIG BAY AND MQT CITY...AS STRONG SOUTHWESTERLY WINDS CONTINUE. INCREASED POPS FOR TOMORROW AFTERNOON AND EVENING. BY LATE TOMORROW MORNING STRONG STRAIGHT UPPER LEVEL JET...115KT+...WILL MOVE OVER THE UPPER GREAT LAKES AND PROVIDE SOME LIFT...WHILE MAIN FORCING IS CONFINED AHEAD OF THE COLD FRONT PROGGED TO PASS THROUGH FA TOMORROW EVENING/NIGHT. STRONG SHEAR...INSTABILITY AND 850 THETA-E RIDGING MOVING INTO THE FA DURING THIS TIME WILL LEAD TO THE FORMATION OF WELL ORGANIZED CONVECTION. MAIN CONCERN CONTINUES TO BE DAMAGING WINDS DURING THIS TIME. && .AVIATION (FOR THE 18Z TAF ISSUANCE)... S WINDS HAVE BECOME GUSTY IN WAKE OF WARM FRONT PASSING INTO SOUTHERN LAKE SUPERIOR. THUNDERSTORMS ARE FIRING OFF OVR SE WI AND OVR WESTERN WI. BEST THREAT FOR THUNDERSTORMS WILL BE AFT 20Z AT BOTH KCMX AND KSAW AS THE STORMS MOVE NORTH AT 50-60 MPH. MAIN THREAT FROM STORMS WILL BE DAMAGING WINDS CONSIDERING WINDS UP TO 60 MPH JUST ABOVE THE SFC. AS A RESULT OF THE STRONG WINDS ALOFT ...KEPT LLWS AT CMX THROUGH MID AFTN. ALL THUNDERSTORMS WILL BE DONE BY EARLY EVENING...WITH VFR CONDITIONS THROUGH THE REST OF THE TAF PERIOD. NEXT CHANCE FOR THUNDERSTORMS ARRIVES EARLY SAT AFTN. && .MARINE (FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)... DEEP LOW PRES FOR JUNE OVER NORTHEAST SOUTH DAKOTA WILL TRACK THROUGH NW MN THIS AFTERNOON AND TO HUDSON BAY SAT. AS THE WARM FRONT AND PRES FALLS LIFT N TOWARD LAKE SUPERIOR EARLY TODAY EXPECT STRONG EASTERLY WINDS ESPECIALLY OVER WRN LAKE SUPERIOR WHERE FUNNELING/CONVERGENCE PREVAIL. SUSTAINED WINDS TO 30 KT WITH A FEW GALE FORCE GUSTS TO 35 KT BTWN THE APOSTLE ISLANDS AND THE MN N SHORE WILL SPREAD INTO CNTRL LAKE SUPERIOR MIDDAY. STABLE CONDITIONS WITH FLOW OF WARM AIR OVER THE COLD LAKE WATERS WILL KEEP BULK OF STRONGER 925-950 SRLY WINDS THIS AFTERNOON AND EVENING IN THE 40-50 KT RANGE FROM MIXING THROUGH THE MARINE LAYER. ARRIVAL OF A MORE HUMID AIRMASS ALONG WITH SHOWERS/THUNDERSTORMS AT TIMES WARRANTS INCLUSION OF FOG IN FCST. AFTER COLD FRONT PASSES FRI EVENING...WINDS WILL INCREASE AGAIN OVER WRN LAKE SUPERIOR. WINDS WILL DIMINISH ACROSS THE LAKE SAT...ESPECIALLY OVER WRN LAKE SUPERIOR. WINDS WILL BE DIFFICULT TO DISCERN FOR SUN/MON TIME FRAME DUE TO UNCERTAINTY IN TIMING/LOCATION OF ADDITIONAL WAVES OF LOW PRES MOVING NE FROM THE PLAINS. && .MQT WATCHES/WARNINGS/ADVISORIES...
