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 Jul 17, 2:54 PM EST, 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 354 PM EDT WED JUL 17 2013 .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 341 AM EDT WED JUL 17 2013 THE CWA IS /AND WILL CONTINUE THROUGH THE SHORT TERM/ BETWEEN A HIGH OVER FAR SRN LAKE MI AND A LOW OVER NRN HUDSON BAY...PUTTING THE CWA ON THE SRN EDGE OF THE WESTERLIES. A WEAK TROUGH JUST UPSTREAM OF THE CWA WILL SLOWLY MOVE THROUGH THE CWA TODAY...DRAGGING A WEAK FRONTAL BOUNDARY WITH IT. MIXING TO AROUND 800MB THIS AFTERNOON WILL LEAD TO HIGHS PRIMARILY IN THE 80S TO MID 90S. THIS RESULTS IN DRY LOW VERY LOW LEVELS...WITH MOISTURE AROUND 800MB. CAPE VALUES THIS AFTERNOON THEN LOOK TO BE 1500-2000J/KG...WITH NEARLY UNIDIRECTIONAL 0-6KM BULK SHEAR VALUES OF 30-40KTS. THIS WILL BE SUFFICIENT FOR A FEW STRONG TO SEVERE THUNDERSTORMS ACROSS THE REGION. EXPECT INITIAL FOCUS FOR THUNDERSTORMS OVER NCENTRAL UPPER MI ALONG THE LAKE BREEZE BOUNDARY THAT RESULTS FROM LIGHT SFC WINDS. CONVECTION WILL THEN SPREAD ACROSS MUCH OF INTERIOR UPPER MI AS THE BOUNDARY AND LAKE BREEZES MOVE INLAND. COVERAGE OF THUNDERSTORMS IS EXPECTED TO BE FAIRLY HIGH...BUT SEVERE COVERAGE IS MORE UNCERTAIN. SPC LEFT THE CWA OUT OF A SLIGHT RISK TODAY BECAUSE THEY WERE WORRIED ABOUT SEVERE STORM COVERAGE. MAIN RISKS WOULD BE HAIL AND WINDS FROM THE THUNDERSTORMS...DUE TO THE HIGH CAPE AND DRY LOW LEVELS THAT WILL ENHANCE DOWN DRAFTS. DCAPE VALUES LOOK TO BE UP TO 1000J/KG AT THE HIGHEST. ALSO...THERE IS SOME CONCERN ABOUT FLASH FLOODING TODAY GIVEN THE SLOW MOVEMENT OF THE BOUNDARIES PARALLEL WLY FLOW POSSIBLY LEADING TO TRAINING THUNDERSTORMS...ALTHOUGH THAT WILL DEPEND ON INDIVIDUAL STORM TRACK SO IT IS TOO EARLY TO TELL WHERE THAT MAY HAPPEN. PWAT VALUES SHOULD BE 1.5-1.75 INCHES...OR 150-175 PERCENT OF NORMAL. SINCE MOST OF THE CONVECTION WED AFTERNOON INTO EARLY WED NIGHT IS DIURNALLY DRIVEN...SHOULD SEE A REDUCTION IN OVERALL PRECIP COVERAGE LATE WED NIGHT. HOWEVER...MCS ACTIVITY NEARBY MAKES POPS MORE UNCERTAIN FOR LATE WED NIGHT AS IT APPEARS CONVECTIVE CLUSTER/S/ MAY MOVE THROUGH THE CWA. STILL QUITE UNCERTAIN FOR THIS PERIOD...BUT IF ANY ACTIVITY DOES MOVE ACROSS THE CWA...STRONG WINDS MAY BE A THREAT AS LOW LEVELS ABOVE THE SFC INVERSION WILL BE DRY /SIMILAR TO WED/...WHICH WILL STRENGTHEN COLD POOL PROCESSES. LOCALLY HEAVY RAIN WILL CONTINUE TO BE A THREAT...ESPECIALLY SINCE PWATS WILL INCREASE TO JUST BELOW 2 INCHES /200 PERCENT OF NORMAL/ BY LATE WED NIGHT. .LONG TERM...(THURSDAY THROUGH TUESDAY) ISSUED AT 341 AM EDT WED JUL 17 2013 THU/THU NGT...THE UPR GRT LKS WL BE ON THE SRN EDGE OF STRONG WLY FLOW OVER SRN CANADA ON THU...A FAVORABLE LOCATION FOR SVR TS OUTBREAKS IN THE SUMMER. AS A FAIRLY POTENT SHRTWV EMBEDDED IN THIS FLOW MOVES FM NEAR LK WINNIPEG AT 00Z FRI INTO NRN MN AT 12Z FRI AND ACCOMPANYING DPVA/LARGER SCALE QVECTOR CNVGC INTERACTS WITH PWAT AS HI AS 2 INCHES OVER THE UPR LKS...SHRA/TS APPEAR TO BE A GOOD BET OVER THE CWA DURING THIS TIME. WITH THE APRCH OF THIS SHRTWV...STNRY FNT OVER UPR MI EARLY THU IS PROGGED TO DRIFT N AS A WARM FNT ON THU AND INTO LK SUP ON THU NGT...INCRSG THE CHC OF MORE SUNSHINE/DAYTIME HEATING THAT WL ENHANCE THE CONSIDERABLE INSTABILITY ASSOCIATED WITH H85 TEMPS ARND 20C/SSI AS LO AS -3 TO -5C DESPITE RATHER MODEST MID LVL LAPSE RATES. WITH THE ARRIVAL OF STRONGER H5 WINDS LATER THU UNDER SLOWLY FALLING HGTS...DEEP LYR SHEAR IS PROGGED TO REACH 40-50 KTS...HIEST OVER THE NRN TIER WHERE THE WARM FNT IS MOST LIKELY TO BE LOCATED AND WHERE MORE DIRECTIONAL SHEAR WOULD BE IN PLACE. WITH VERY HUMID AIRMASS/SFC DEWPTS AT LEAST NEAR 70/RATHER LO LCLS...A RARE U.P. TORNADO MIGHT NOT BE OUT OF THE QUESTION OVER THE NRN TIER BEFORE THE FNT SHIFTS INTO THE LK ON THU NGT. NOT SURPRISINGLY...SPC HAS PLACED THE CWA IN A SLGT RISK FOR SVR WX DURING THIS PERIOD. TORRENTIAL RA/FLASH FLOODING WL ALSO BE A CONCERN WITH UPR FLOW PARALLEL TO SLOW MOVING FNT ON THU...A SETUP THAT WOULD FAVOR TRAINING OF CELLS IN VERY MOIST ENVIRONMENT WITH HI FRZG LVL NEAR 15K FT. AT THIS POINT...TIMING OF HIER POPS/TS CHCS IS PROBLEMATIC AT BEST...BUT LIKELY POPS APPEAR TO BE IN ORDER ESPECIALLY THU EVNG WHEN THE MOST IMPRESSIVE DYNAMICS ARE FCST TO REACH THE AREA IN PRESENCE OF GREATER INSTABILITY. WITH THE CWA LIKELY TO BE IN THE WARM SECTOR ON THU NGT...ADJUSTED FCST TEMPS UP A COUPLE OF DEGREES. FRI...AS UPR DISTURBANCE PASSES NW-SE THRU THE UPR LKS...SFC COLD FNT IS PROGGED TO PASS THRU THE CWA. THE THREAT FOR SHRA/TS SHOULD DIMINISH NW-SE WITH THE ARRIVAL OF DRIER AIR BEHIND THE FROPA...BUT STEEPENING MID LVL LAPSE RATES AND DRYING SHOWN ON THE GFS/NAM FCST SDNGS BEFORE THE DRIER AIR ARRIVES NEAR THE SFC MIGHT PROLONG THE TS THREAT LONGER OVER THE SE COUNTIES...ESPECIALLY IF THERE IS MRNG SUNSHINE. THE NW CWA SHOULD BE MUCH COOLER WITH NW FLOW OFF THE RELATIVE CHILLY LK WATERS. FRI NGT...ALTHOUGH VARIOUS MODELS SHOW A TRAILING SHRTWV MOVING THRU THE UPR LKS...PRIOR ARRIVAL OF DRIER/MORE STABLE CNDN AIRMASS AND NOCTURNAL COOLING WL LIMIT SHRA CHCS. OPTED TO GO WITH A DRY FCST AND JUST PCLDY SKIES AS LO TEMPS SINK BACK INTO THE MORE SEASONABLE 50S. SAT/SUN...PLEASANTLY COOL AND STABLE CNDN HI PRES WL BRING A VERY NICE WEEKEND TO THE CWA WITH H85 TEMPS AS LO AS 5C CAUSING DAILY TEMPS TO RUN BLO NORMAL. EARLY NEXT WEEK...NOT SURPRISINGLY...THERE IS CONSIDERABLE DISAGREEMENT ON THE DETAILS OF FCST WNW FLOW ALF FCST TO IMPACT THE UPR LKS. SO WL FOLLOW MODEL CONSENSUS FOR THE FCST...WHICH INDICATES SOME SHRA MAY RETURN ONCE THE WEEKEND HI PRES RETREATS TO THE E. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON) ISSUED AT 349 PM EDT WED JUL 17 2013 VFR CONDITIONS SHOULD GENERALLY PREVAIL THROUGH THE PERIOD AT ALL SITES. LOOK FOR ISOLD TO SCT SHRA/TS TO DEVELOP LATE THIS AFTERNOON AT KIWD AND KSAW ALONG LAKE BREEZE BOUNDARY AND THEN DIE OUT LATE THIS EVENING WITH LOSS OF BETTER HEATING/INSTABILITY. LOOK FOR WIDESPREAD SHRA/TSRA ON THU MORNING AS WARM FRONT LIFTS ACROSS AREA. && .MARINE...(FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 341 AM EDT WED JUL 17 2013 WITH RELATIVELY WEAK PRES GRADIENT AND HI STABILITY OVER THE RELATIVELY COOL LAKE WATERS...EXPECT WINDS NO HIGHER THAN 20 KTS THIS FORECAST PERIOD. THE MAIN WEATHER CONCERN WILL BE FOG WITH A HUMID AIRMASS DOMINATING. THIS FOG IS LIKELY TO BE MOST WIDESPREAD ON THU NIGHT FOLLOWING SOME HEAVY SHOWERS/THUNDERSTORMS THAT WILL FURTHER SATURATE THE MARINE LAYER. THE ARRIVAL OF DRIER AIR ON FRI WILL DISSIPATE THE FOG. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE. LAKE SUPERIOR... NONE. LAKE MICHIGAN...
