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 Jun 22, 5:20 PM CST, 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 720 PM EDT MON JUN 22 2015 .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 418 PM EDT MON JUN 22 2015 WV IMAGERY AND RAP ANALYSIS INDICATED A ZONAL PATTERN ACROSS THE NRN CONUS WITH A SHORTWAVE TROUGH FROM NW ONTARIO INTO NRN MN. THE RESIDUAL MCV GENERATED FROM THE LARGE MCS EARLIER TODAY WAS LOCATED NEAR NW LOWER MI. FORCING ASSOCIATED WITH THIS FEATURE AND 305K-310K ISENTROPIC ASCENT AHEAD OF THE SHRTWV SUPPORTED SOME SHRA OVER NRN UPPER MI. AT THE SFC...A COLD FRONT EXTENDED ACROSS ERN MN. SCT SHRA AND ISOLATED TS HAS ALSO DEVELOPED ALONG AND AHEAD OF THE FRONT WHERE HEIGHT FALLS AHEAD OF THE SHRTWV WERE MOVING IN. CLOUDS AND AREAS OF SHOWERS HAVE LIMITED HEATING/INSTABILITY WITH HIGHEST SB/MU CAPE VALUES ONLY UP TO AROUND 500 J/KG OVER THE WEST. EXPECT SCT SHRA/TSRA TO CONTINUE TO PUSH FROM NW WI THROUGH UPPER MI THIS EVENING. ALTHOUGH 0-6KM/0-1KM SHEAR VALUES OF 40-60KT/25-35KT WOULD BE FAVORABLE FOR SOME STRONG/SVR STORMS. EVEN WITH SOME ADDITIONAL CAPE RECOVERY...THE MARGINAL INSTABILITY WILL LIMIT THE SVR POTENTIAL. NEVERTHELESS...AN ISOLATED SVR STORM CANNOT BE RULED OUT. THE SCT SHRA/TSRA ARE EXPECTED TO MOVE OUT OF THE CNTRL AND EAST BTWN 03Z-06Z WITH DRY WEATHER THE REST OF THE NIGHT. GUSTY WINDS WILL DEVELOP BEHIND THE FRONT AND LOW PRES WITH THE PRES RISE MAX MOVING THROUGH THIS EVENING AND A TIGHT PRES GRADIENT LINGERING OVERNIGHT. TUE...HIGH PRES BUILDING FROM THE UPPER MS VALLEY INTO THE WRN GREAT LAKES WITH MUCH DRIER AIR WILL BRING MOSTLY SUNNY SKIES...BREEZY NW WINDS AND TEMPS NEAR SEASONAL AVERAGES FROM THE LOWER TO MID 70S. .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 325 PM EDT MON JUN 22 2015 SEVERAL SHORTWAVES WILL AFFECT THE UPPER GREAT LAKES REGION THROUGH THE REST OF THE WORK WEEK AND INTO THE WEEKEND...WHICH WILL SLOWLY DEVELOP AN UPPER TROUGH OVER THE GREAT LAKES REGION THIS WEEKEND. ONCE THE UPPER TROUGH BECOMES ESTABLISHED IN THE GREAT LAKES REGION...ECMWF/GFS ENSEMBLES ARE CONSISTENT ON THE UPPER RIDGE DEVELOPING OVER THE PACIFIC NORTHWEST THIS WEEKEND TO SLOWLY SHIFT TO THE NORTHWEST AND REMAIN IN PLACE THROUGH THE FIRST WEEK OF JULY. THAT WILL LEAD TO A PERSISTENT PERIOD OF NORMAL TO BELOW NORMAL TEMPERATURES FOR THE GREAT LAKES REGION. SHIFTING BACK TO THIS WEEK...THE FIRST WAVE THAT WILL AFFECT THE CWA WILL BE MOVING ACROSS FAR NORTHERN ONTARIO ON TUESDAY NIGHT...WITH SOUTHWESTERN EDGE OF THAT WAVE BRUSHING THE NORTHEAST PART OF LAKE SUPERIOR. AT THE SURFACE...A WEAK TROUGH WILL BE MOVING ACROSS THE LAKE AND EXPECT THERE TO BE SOME SHOWERS ALONG IT IN NORTHWEST ONTARIO ON TUESDAY AFTERNOON. BUT WITH THE LOSS OF DIURNAL HEATING...LIMITED MOISTURE...AND THE BEST FORCING STAYING WELL TO THE NORTHEAST OF THE CWA...WILL ONLY SHOW SLIGHT CHANCE POPS MOVING SOUTHEAST ACROSS NORTHEAST LAKE SUPERIOR. DID BRUSH THE KEWEENAW WITH THOSE SLIGHT CHANCE POPS WITH A DECENT NUMBER OF MODELS SHOWING A FEW HUNDREDTHS OF QPF. OTHERWISE...EXPECT THE REST OF THE AREA TO BE PARTLY CLOUDY TO MOSTLY CLEAR ON TUESDAY NIGHT DUE TO THE RESIDUAL EFFECTS OF THE SLOWLY DEPARTING SURFACE RIDGE. THAT SURFACE RIDGE WILL STILL BE OVER THE GREAT LAKES REGION ON WEDNESDAY MORNING...AS THE PARENT HIGH MOVES INTO THE MID ATLANTIC STATES. BUT THE NEXT SHORTWAVE WILL BE QUICKLY APPROACHING THE AREA ON WEDNESDAY AFTERNOON. MODELS CONTINUE TO DEPICT LINGERING MOISTURE ASSOCIATED WITH THE TUESDAY NIGHT SURFACE TROUGH BEING OVER THE U.P. ON WEDNESDAY AFTERNOON AND THAT WILL COMBINE WITH THE ARRIVAL OF ADDITIONAL MOISTURE/FORCING AND LAKE BREEZE DEVELOPMENT TO LEAD TO SHOWERS AND A FEW THUNDERSTORMS OVER PORTIONS OF WEST/CENTRAL UPPER MICHIGAN. WILL CONTINUE TO SHOW THE BEST CHANCE FOR SHOWERS OVER THE LAND AREAS AND INLAND FROM THE GREAT LAKES...WITH THE BEST OPPORTUNITY ALONG THE EXPECTED LAKE BREEZE FROM CENTRAL MARQUETTE COUNTY WESTWARD TOWARDS ONTONAGON COUNTY. WILL CONTINUE TO KEEP THUNDER VALUES IN THE SLIGHT CHANCE CATEGORY WITH MLCAPE VALUES GENERALLY UNDER 500J/KG (BEST INSTABILITY WELL TO THE SOUTH AND TIED TO THE STRONG STORMS LIKELY MOVING THROUGH SOUTHERN MINNESOTA/WISCONSIN LATE WEDNESDAY AFTERNOON/NIGHT). 0-6KM BULK SHEAR VALUES LOOK FAIRLY STRONG (APPROACHING 50KTS)...BUT LOOKING AT THE SOUNDINGS...THAT IS ALL TIED TO THE STRONG JET BETWEEN 5-6KM. THUS...THINK THE EFFECTIVE SHEAR VALUES AROUND 20KTS ARE MORE REASONABLE AND BELIEVE THE POTENTIAL FOR STRONG STORMS IS LIMITED AT THIS POINT. THE ONLY CONCERN WOULD BE WITH THE SLOW STORM MOTIONS LEADING TO LOCALIZED HEAVY RAIN WHERE THE THUNDERSTORMS OCCUR. WHILE THAT FIRST WAVE WILL AFFECT THE AREA WEDNESDAY AFTERNOON/EVENING...THERE ARE SEVERAL WEAK WAVES TRAILING IT THAT WILL HAVE AN INFLUENCE ON THE WEATHER FOR THE U.P. THROUGH THURSDAY NIGHT. WILL SHOW CHANCE POPS AS THESE DISTURBANCES MOVE THROUGH AND CONTINUE SLIGHT CHANCE FOR THUNDER (ALTHOUGH THAT APPEARS TO BE FAIRLY OPTIMISTIC). THOSE WAVES WILL AMPLIFY AN UPPER TROUGH OVER THE GREAT LAKES REGION THIS WEEKEND AND LIKELY CONTINUE INTO EARLY JULY. THERE IS THE POTENTIAL FOR SOME DIURNAL SHOWERS THIS WEEKEND...ALTHOUGH THE SUBSIDENCE FROM A HIGH PRESSURE RIDGE MOVING THROUGH SHOULD LIMIT THE COVERAGE...BEFORE ANOTHER STRONGER WAVE DROPS SOUTHEAST ACROSS THE AREA ON MONDAY. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY EVENING) ISSUED AT 720 PM EDT MON JUN 22 2015RAPID CHANGE AT ALL SITES THIS EVENING AS A COLD FRONT MOVES QUICKLY THROUGH. CONDITIONS WILL BE MOSTLY VFR FOR THIS FORECAST PERIOD WITH BRIEF MVFR ALONG THE FRONT THIS EVENING AS SHOWERS MOVE THROUGH. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 418 PM EDT MON JUN 22 2015 A LOW PRES SYSTEM WIL MOVE EAST OF LAKE SUPERIOR TONIGHT. A TIGHT PRES GRADIENT AND COLD ADVECTION ON THE BACK SIDE OF THIS LOW WILL SUPPORT A PERIOD OF WNW 35 KNOT GALES LATE TONIGHT INTO TUE MORNING...STRONGEST OVER THE EAST HALF OF LAKE SUPERIOR. HIGH PRES BUILDING BACK OVER THE AREA WILL THEN KEEP WINDS LIGHT AGAIN FROM LATE TUE INTO FRI. LINGERING LOW-LVL MOISTURE AND HIGH DEWPOINTS WILL SUPPORT FOG ACROSS THE LAKE...THAT COULD BE LOCALLY DENSE INTO THIS EVENING. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE. LAKE SUPERIOR... GALE WARNING FROM 1 AM TO 10 AM EDT TUESDAY FOR LSZ251-266-267. LAKE MICHIGAN...
