The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Marquette, MI wrote its last area forecast discussion before the first event at Sep 17, 11:56 AM CST, 1 hour 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 156 PM EDT THU SEP 17 2015 .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 446 AM EDT THU SEP 17 2015 SW UPPER LEVEL FLOW CONTINUES BETWEEN AN UPPER RIDGE EXTENDING FROM TX TO THE LOWER GREAT LAKES AND E COAST AND AN UPPER TROUGH OVER THE WRN CONUS. SHORTWAVES ARE MOVING THROUGH THE REGION IN THE SW FLOW. ONE WEAK SHORTWAVE IS OVER THE MN/NWRN WI BORDER AND IS DRIVING SOME SHOWERS AND THUNDERSTORMS SW OF THE CWA AND ANOTHER IS NW OF THE CWA WITH SOME CONVECTION THERE. STEEP MID-UPPER LEVEL LAPSE RATES CONTINUES TO ALSO BE A FACTOR IN THE CONVECTION. DRY LOW LEVEL AIR OVER UPPER MI (DRIEST CENTRAL AND E AS MOISTURE MOVES INTO THE W) IS KEEPING MUCH OF THE ELEVATED SHOWERS THAT ARE ISOLATED IN COVERAGE OVER PORTIONS OF THE CWA FROM REACHING THE GROUND. THE PRIMARY WEATHER MAKER IN THE SHORT TERM IS A SHORTWAVE AND SFC LOW OVER ND EARLY THIS MORNING. THE SFC LOW WILL SHIFT ACROSS NRN MN AND INTO WRN NRN ONTARIO BY 18Z TODAY THEN TO JAMES BAY BY 12Z FRI. THE SFC TROUGH/COLD FRONT WILL MOVE INTO THE WRN CWA BY 00Z FRI AND WILL BE NEAR NEWBERRY AT 12Z FRI. EXPECT GOOD COVERAGE OF SHOWERS AND THUNDERSTORMS ALONG AND AHEAD OF THE FRONT AS IT INTERACTS WITH A MOISTURE RICH (PWATS OF 1.5-1.75 INCHES) AND UNSTABLE (MLCAPES AS HIGH AS 1000-1300 J/KG) ENVIRONMENT. BEST INSTABILITY WILL BE OVER THE W HALF OF THE CWA DURING THE AFTERNOON. LOOKS LIKE AN ADDITIONAL SHORTWAVE WILL MOVE ACROSS THIS AFTERNOON...WHICH SHOULD DEVELOP CONVECTION AHEAD OF THE FRONT. 0-6KM BULK SHEAR WILL BE WEAK AT 20- 25KTS THIS AFTERNOON WHEN CAPE IS GREATEST...AND SHEAR INCREASES TO 30-35KTS ALONG THE FRONT WHEN CAPE IS REDUCED TO AOB 1000 J/KG. THEREFORE...SEVERE POTENTIAL IS LOW...WITH THE BEST CHANCES FOR STRONG STORMS OVER THE W WHERE THE BETTER SHEAR MAY LINE UP WITH BETTER INSTABILITY EARLIER IN THE EVENING. BRIEF HEAVY RAIN IS ALSO EXPECTED. SPC RISK REDUCTION FROM SLIGHT TO MARGINAL MAKES SENSE...BUT THINK THAT MARGINAL RISK IS ONLY NEEDED OVER THE WRN CWA. BY LATE TONIGHT/EARLY FRI...THE W WILL BE DRY WITH SOME SCATTERED SHOWERS OVER THE E...ISOLATED CENTRAL. TODAY WILL SEE HIGHS IN THE 70S IN MOST LOCATIONS...WITH LOW TO MID 80S EXPECTED NEAR LAKE SUPERIOR DUE TO DOWNSLOPING. WILL SEE ANOTHER GUSTY DAY WITH GUSTS TO 20-30MPH FROM THE SSW .LONG TERM...(FRIDAY THROUGH WEDNESDAY) ISSUED AT 506 AM EDT THU SEP 17 2015 CURRENT WRN CONUS TROF AND ERN CONUS RIDGE WILL GIVE WAY TO LOWER AMPLITUDE FLOW BY LATE WEEKEND AS A PAIR OF SHORTWAVES HELP SHIFT THE WRN TROF EASTWARD WHILE DEAMPLIFYING. THE FIRST WAVE WILL LIFT INTO NRN ONTARIO TONIGHT WITH THE FOLLOWING SHIFTING ACROSS THE GREAT LAKES REGION SAT. THESE CHANGES WILL RESULT IN OUR RECENT STRING OF WELL ABOVE NORMAL TEMPS FALLING BACK TO NEAR NORMAL BY SAT. WARMING WILL BEGIN AGAIN EARLY NEXT WEEK UNDER LOW AMPLITUDE FLOW FEATURING BLO NORMAL HEIGHTS IN WRN CANADA AND ABOVE NORMAL HEIGHTS FROM THE MISSISSIPPI VALLEY TO SE CANADA. LOOKING FARTHER OUT...LONGER RANGE GUIDANCE POINTS TO ABOVE NORMAL TEMPS BEING FAVORED ON THE MAJORITY OF DAYS FOR AT LEAST THE NEXT 2 WEEKS...AND CFS RUNS HAVE BEEN INDICATING A TENDENCY FOR ABOVE NORMAL TEMPS OUT INTO EARLY OCT. AS FOR PCPN OVER THE NEXT 7 DAYS...ONE PERIOD OF PCPN WILL OCCUR TODAY/TONIGHT AS A COLD FRONT SWEEPS ACROSS THE UPPER GREAT LAKES IN ASSOCIATION WITH FIRST SHORTWAVE NOTED ABOVE. ANOTHER SHOT OF PCPN WILL OCCUR FRI NIGHT INTO SAT MORNING IN ASSOCIATION WITH SECOND SHORTWAVE AS IT SUPPORTS A SFC WAVE TRACKING NE ALONG COLD FRONT THAT PASSES TONIGHT. THE SE PORTION OF THE FCST AREA WILL HAVE THE BEST OPPORTUNITY FOR PCPN WITH THE SECOND SHORTWAVE. BEGINNING FRI...COLD FRONT WILL EXIT THE ERN FCST AREA BY MID MORNING AT THE LATEST...BRINGING AN END TO ANY LINGERING PCPN OVER THE E. OTHERWISE...DECENT COLUMN DRYING AND SFC HIGH PRES RIDGE NOSING INTO UPPER MI/LAKE SUPERIOR SUGGEST A DRY PERIOD OF WEATHER FRI. WITH SLOW COOLING BEHIND THE COLD FRONT FRI (850MB TEMPS FALL TO ROUGHLY 8C W TO 11C E BY EVENING)...MAX TEMPS WILL END UP CLOSE TO OR A LITTLE ABOVE NORMAL IN THE MID 60S TO LWR 70S. ATTENTION THEN TURNS TO NEXT SHORTWAVE THAT WILL REACH THE WRN GREAT LAKES LATE FRI NIGHT/SAT MORNING. SHORTWAVE WILL SPIN UP A SFC WAVE ALONG THE COLD FRONT THAT PASSES ACROSS THE AREA TONIGHT. THAT LOW WILL TRACK NE ACROSS LWR MI SAT MORNING. THE NAM CONTINUES TO BE A SLOW AND SOMEWHAT DEEP OUTLIER AND HAS SFC LOW TRACK AND HEAVIER PCPN FARTHER NW THAN OTHER GUIDANCE. WHILE 06Z/12Z/18Z GFS RUNS TRENDED IN THAT DIRECTION...THE 00Z 9/17 RUN IS BACK TO A LIGHTER PCPN SCENARIO AND WEAKER SFC LOW...SIMILAR TO THE MAJORITY OF GUIDANCE FROM THE 00Z 9/16 CYCLE. WITH TONIGHTS 00Z RUNS...THE GFS/CMC ARE VERY SIMILAR WHILE THE ECWMF...JUST LIKE ITS 12Z RUN...LENDS SOME SUPPORT FOR A NAM-LIKE SOLUTION...BUT WITH TIMING SIMILAR TO THE GFS/GEM. WILL DISCARD THE NAM AND USE THE GFS/GEM/ECMWF FOR THE BASIS OF THE FCST. OVERALL...THIS LEADS TO ONLY MINOR ADJUSTMENTS TO INHERITED FCST. PCPN SHOULD SPREAD NE ACROSS THE AREA FRI NIGHT WITH LOWEST POPS W AND HIGHEST POPS SCNTRL/E. IT'S QUITE POSSIBLE THE FAR W MAY NOT SEE ANY PCPN. PCPN WILL EXIT THE E SAT MORNING...FOLLOWED BY CLEARING FROM W TO E DURING THE DAY. THIS SHOULD ALLOW TEMPS TO RISE INTO THE MID 60S W. WITH LATER CLEARING...HIGHS SHOULD BE AROUND 60F TO LWR 60S E. WITH AXIS OF MIN PRECIPITABLE WATER SHIFTING E OF THE AREA SAT EVENING AND WITH CENTER OF HIGH PRES PASSING S OF THE AREA...SAT NIGHT WON'T BE AN IDEAL RADIATIONAL COOLING NIGHT. NONETHELESS... FAVORED THE LOWER SIDE OF GUIDANCE WHICH PUTS MIN TEMPS DOWN AROUND 40F IN THE TRADITIONAL COLD SPOTS. DRY WEATHER/WARMING WILL BE THE RULE SUN/MON UNDER SW FLOW AS HIGH PRES SHIFTS TO NEW ENGLAND AND A COLD FRONT EVENTUALLY MOVES OUT ACROSS THE NRN PLAINS TOWARD THE UPPER LAKES. WARMING CONTINUES TUE...AND DRY WEATHER WILL PROBABLY CONTINUE AS WELL. EACH DAY... AFTN HIGH TEMPS WILL BE A LITTLE HIGHER THAN THE PREVIOUS DAY... REACHING THE LOW/MID 70S OVER MOST OF THE AREA BY TUE. APPROACHING COLD FRONT MAY BRING THE POTENTIAL FOR SHRA AT SOME POINT TUE NIGHT/WED...BUT AN EXPLICIT MENTION OF PCPN DOES NOT APPEAR WARRANTED SINCE SHORTWAVE SUPPORTING THE COLD FRONT WILL BE PASSING WELL TO THE NW OF HERE. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON) ISSUED AT 154 PM EDT THU SEP 17 2015 SHOWERS WITH A FEW THUNDERSTORMS OVER WESTERN UPR MICHIGAN SLOWLY MOVE EAST THROUGH THE AFTN...AFFECTING KCMX AND KSAW INTO THE EVENING. WILL ALSO SEE POTENTIAL OF ADDITIONAL SHRA/TSRA LATER THIS EVENING JUST AHEAD OF COLD FRONT THAT MOVES THROUGH OVERNIGHT. EXPECT PERIOD OF LOW CLOUDS...LOW MVFR OR PERHAPS EVEN IFR...AND FOG OR DRIZZLE LATE TONIGHT INTO FRIDAY MORNING BEHIND THE COLD FRONT. CONDITIONS SHOULD IMPROVE ON FRIDAY AFTN TO VFR AGAIN AS CLOUDS BEGIN TO CLEAR OUT. && .MARINE...(FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 446 AM EDT THU SEP 17 2015 GUSTY SOUTHERLY WINDS WILL REMAIN IN PLACE TODAY INTO TONIGHT AS THE UPPER GREAT LAKES REGION IS BETWEEN HIGH PRESSURE IN THE MID ATLANTIC STATES AND A LOW THAT WILL BE MOVING NORTHEAST ACROSS ONTARIO. THESE SOUTHERLY WINDS WILL GENERALLY BE IN THE 15-25KT RANGE...BUT WITH VERY STRONG WINDS JUST ABOVE THE SURFACE...COULD SEE SOME STRONGER GUSTS TO 30KTS AT TIMES OVER EASTERN LAKE SUPERIOR. A COLD FRONT MOVING EAST ACROSS LAKE SUPERIOR TONIGHT WILL SHIFT WINDS TO THE NORTHWEST UP TO 20KTS. THE WINDS WILL DIMINISH THROUGH THE DAY ON FRIDAY AS A HIGH PRESSURE RIDGE QUICKLY BUILDS INTO THE AREA. ON FRIDAY NIGHT...A SURFACE LOW WILL DEVELOP ALONG THE COLD FRONT THAT MOVED THROUGH ON THURSDAY NIGHT AND MOVE THROUGH LOWER MICHIGAN. THIS WILL SHIFT WINDS MORE OUT OF THE NORTHERLY DIRECTION UP TO 25 KNOTS LATE FRIDAY NIGHT INTO SATURDAY MORNING. A LARGE HIGH PRESSURE RIDGE WILL BUILD OVER THE GREAT LAKES REGION SATURDAY NIGHT AND REMAIN INTO MONDAY AND KEEP WINDS BELOW 20KTS. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE.
