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 30, 11:51 AM EST, 1 hour 34 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 1251 PM EDT SAT JUL 30 2011 .UPDATE... SHOWERS AND THUNDERSTORMS AHEAD OF A CONVECTIVELY INDUCED SHORTWAVE OVER MN HAVE MOVED INTO THE WRN FORECAST AREA. WITH MODELS INDICATING 1500-2500J/KG OF SBCAPE AND LITTLE CIN...STORMS ARE EXPECTED TO MOVE/DEVELOP OVER THE CWA THIS AFTERNOON INTO THIS EVENING. WIND SHEAR IS FAIR WEAK AT 25-35KTS...SO STORMS SHOULD NOT BECOME INCREDIBLY ORGANIZED. NORTHERN BOUND FOR MOST OF THE CONVECTION WILL BE THE LAKE SUPERIOR BREEZE...WHICH WILL REMAIN FAIRLY CLOSE TO SHORE GIVEN STEADY SW WINDS...AND MAY ACT TO LOCALLY INTENSIFY STORMS. STORMS SHOULD STAY FOCUSED OVER THE WRN CWA AS LAKE MODERATION OFF LAKE MI OVER THE ERN CWA WILL NOT BE FAVORABLE FOR THE CONVECTION. GIVEN THE CURRENT LINEAR STRUCTURE OF THE STORMS...STRONG TO SEVERE WINDS APPEARS TO BE THE PRIMARY THREAT...BUT THERE IS A LARGE HAIL THREAT AS WELL. TORNADO POTENTIAL APPEARS VERY LOW GIVEN WEAK SHEAR AND LINEAR NATURE OF STORMS. STORM DEVELOPMENT/MAINTENANCE WILL BE AIDED BY WAA ONGOING OVER THE CWA...AND THETA-E ADVECTION AHEAD OF THE CONVECTIVE LINE. && PREV DISCUSSION...ISSUED AT 752 AM EDT SAT JUL 30 2011... .SYNOPSIS... WATER VAPOR IMAGERY AND RUC ANALYSIS CONTINUE TO SHOW NEARLY ZONAL FLOW ACROSS THE NRN CONUS TO THE N OF AN EXPANSIVE HIGH PRES RIDGE ACROSS THE SRN CONUS. TWO MAIN SHORTWAVES ARE EMBEDDED IN THE WRLY FLOW. ONE IS MOVING THRU SE CANADA AND NEW ENGLAND WHILE THE SECOND IS OVER SASKATCHEWAN. A MINOR SHORTWAVE OVER THE ERN DAKOTAS APPEARS TO BE BECOMING BETTER DEFINED AND IS ACCOMPANIED BY A CLUSTER OF SHRA/TSRA. CLOSER TO HOME...WEAK RIDGING AHEAD OF SASKATCHEWAN SHORTWAVE IS SUPPORTING SFC HIGH PRES OVER THE MIDWEST AND WRN GREAT LAKES. RESULT HAS BEEN A GENERALLY QUIET NIGHT ACROSS THE FCST AREA...THOUGH THERE HAVE BEEN PESKY ISOLD -SHRA OCCURRING OVER PORTIONS OF THE SW INTO SCNTRL FCST AREA. && .DISCUSSION... FCST IN THE SHORT TERM WILL REVOLVE AROUND MAIN SHORTWAVE CURRENTLY TRACKING THRU SASKATCHEWAN AND THE OTHER SHORTWAVE OVER THE ERN DAKOTAS. IN THE LONGER TERM...OVERALL PATTERN WILL CONTINUE TO SUPPORT ABOVE NORMAL TEMPS THRU THIS FCST PERIOD. BEST POTENTIAL FOR PCPN MAY OCCUR MON NIGHT/TUE WITH SHORTWAVE PASSING THRU THE UPPER GREAT LAKES. WAA AND MOISTURE ADVECTION WILL GET UNDERWAY TODAY AHEAD OF SHORTWAVE TRACKING FROM SASKATCHEWAN TO NRN ONTARIO. AHEAD OF THIS FEATURE...THE SHORTWAVE CURRENTLY OVER THE ERN DAKOTAS SHOULD TRACK ACROSS UPPER MI THIS AFTN. TIMING WILL FAVORABLY COINCIDE WITH MAX DAYTIME HEATING AND BUILDING INSTABILITY...AND SINCE WAVE APPEARS TO BE BECOMING BETTER DEFINED...CONVECTION NEEDS TO BE CONSIDERED. THERE IS SOME CONCERN THAT WAVE WILL OUTRUN THE BETTER MOISTURE RETURN...BUT FCST SOUNDINGS LOOK SUPPORTIVE OF AT LEAST A SMALL POTENTIAL OF CONVECTION. MODIFIED FOR A SFC T/TD OF UPPER 80S/AROUND 60...FCST SOUNDINGS YIELD CAPE OF 1000-1500J/KG. SW WINDS WILL NOT BE STRONG ENOUGH TO COMPLETELY HOLD OFF LAKE SUPERIOR LAKE BREEZE IN ALL AREAS...SO THERE WILL BE A LOW-LEVEL FOCUSING MECHANISM. LAKE MICHIGAN IS NOW BECOMING A SOURCE OF LOW-LEVEL MOISTURE AS WATER CONTINUES TO WARM...AND IT'S NOT OUT OF THE QUESTION THAT LOCALLY HIGHER SFC DWPTS SPREADING N WITH LAKE BREEZE COMPONENT TO PREVAILING WIND COULD ALSO TRIGGER ISOLD CONVECTION FARTHER E AS WELL. WITH THAT SAID...WILL CARRY SLIGHT CHC POPS IN THE LATE AFTN ACROSS THE AREAS WHERE IT APPEARS THERE WILL BE SOME LOW-LEVEL CONVERGENCE DEVELOPING...GENERALLY THE WRN AND NRN FCST AREA. MIXING TO 800-750MB SUPPORTS MAX TEMPS WELL INTO THE UPPER 80S AWAY FROM ANY LAKE MODERATION. IF THERE IS ANY CONVECTION THIS AFTN...IT WILL PROBABLY TEND TO DIMINISH/POSSIBLY END IN THE EVENING AS SHORTWAVE EXITS. ATTENTION THEN TURNS TO MAIN SHORTWAVE SHIFTING E ACROSS NRN ONTARIO. TAIL OF WAVE WILL JUST BRUSH BY THE FCST AREA WITH VERY LITTLE IF ANY HEIGHT FALLS NOTED HERE. AT 00Z...ASSOCIATED COLD FRONT WILL STILL BE WELL TO THE W IN MN. WITH FRONT ARRIVING DURING MIN DIURNAL HEATING TIME AND WITH BULK OF FORCING PASSING BY TO THE N...IT WOULD SEEM THAT SFC BASED CONVECTION THAT WILL BE OCCURRING IN NE MN ALONG/AHEAD OF THE FRONT LATE AFTN/EARLY EVENING SHOULD GENERALLY DECREASE IN INTENSITY/COVERAGE AS IT MOVES INTO UPPER MI DURING THE NIGHT. SO FOR NOW...NOTHING MORE THAN LOWER CHC POPS SEEMS WARRANTED. COLD FRONT WILL SLOWLY SETTLE SSE THRU THE FCST AREA SUN...EXITING MENOMINEE COUNTY IN THE EVENING. EXPECT SOME REDEVELOPMENT OF CONVECTION SUN AS STRENGTHENING LAKE BREEZE COMPONENTS TO THE WIND WILL INCREASE LOW-LEVEL CONVERGENCE INTO FRONTAL BOUNDARY DROPPING THRU THE SCNTRL AND SE FCST AREA DURING PEAK HEATING. THUS...BEST CHC OF SHRA/TSRA WILL BE OVER THE SCNTRL/SE FCST AREA... BUT EVEN THERE...NOTHING MORE THAN CHC POPS WILL BE UTILIZED AS IT APPEARS CONVECTION WILL HAVE LIMITED COVERAGE DUE TO LACK OF STRONGER FORCING AND DUE TO RATHER PRONOUNCED MIDLEVEL DRYING PUSHING INTO THE AREA. MODIFIED FCST SOUNDINGS FOR A SFC T/TD OF UPPER 80S/MID 60S YIELDS CAPE UPWARDS OF 2000-2500J/KG. RISK OF SHRA/TSRA WILL END W AND N BY AFTN IN THE WAKE OF COLD FRONT. WITH DEPARTURE OF COLD FRONT...ANY LINGERING CONVECTION OVER THE FAR SCNTRL WILL END SUN EVENING. WITH MOSTLY CLEAR SKIES...WINDS BECOMING LIGHT...AND PRECIPITABLE WATER FALLING TO 50-75PCT OF NORMAL...TEMPS SHOULD BE ABLE TO RADIATE DOWN TOWARD TYPICAL LATE JULY/EARLY AUG MINS...ESPECIALLY W WHERE SFC HIGH PRES ARRIVES LATE. TEMPS THERE SHOULD FALL TOWARD THE LOWER 50S IN THE INTERIOR. UPPER 50S/LWR 60S SHOULD PREVAIL ELSEWHERE...WARMEST ALONG THE GREAT LAKES. MON...MID/UPPER LEVEL RIDGE AXIS EXTENDING FROM SRN CONUS SUBTROPICAL HIGH WILL SHIFT INTO THE UPPER LAKES. AT THE SFC... ASSOCIATED HIGH PRES WILL SLOWLY SHIFT ACROSS THE UPPER GREAT LAKES. THERE ARE HINTS THAT A MINOR SHORTWAVE MAY EMERGE FROM SUN NIGHT CONVECTION OVER THE NRN PLAINS...AND THAT WAVE MAY TRACK ACROSS THE AREA MON AFTN. EVEN IF IT DOES...IT WILL OUTRUN MOISTURE RETURN... AND THUS SHOULDN'T POSE A RISK OF PCPN HERE MON. RIDGE WILL CONTINUE TO DOMINATE THE SRN CONUS NEXT WEEK. THIS WILL RESULT IN MOSTLY ZONAL FLOW PERSISTING ACROSS THE NRN CONUS/SRN CANADA WITH SHORTWAVES OCCASIONALLY PASSING THRU THE AREA. MODELS STILL SUGGEST NEXT SHORTWAVE WILL AFFECT THE UPPER LAKES MON NIGHT/TUE. STRENGTHENING LOW-LEVEL JET/THETA-E ADVECTION AND ADVECTION OF INSTABILITY WILL LIKELY SUPPORT SHRA/TSRA...POSSIBLY AN MCS ACROSS THE UPPER MISSISSIPPI VALLEY AND GREAT LAKES REGION MON NIGHT/TUE MORNING. PLACEMENT OF CONVECTION IS ALWAYS DIFFICULT...BUT STILL THINK MAIN PUSH OF SHRA/TSRA MAY BE JUST SW OF THE FCST AREA CLOSER TO POOL OF BETTER INSTABILITY DESPITE CONSENSUS OF LATEST ROUND OF MEDIUM RANGE GUIDANCE DRIVING MAIN PCPN AXIS FARTHER N ACROSS UPPER MI AGAIN. SOME AREAS OF UPPER MI ARE GETTING QUITE DRY...SO A WIDESPREAD RAINFALL WOULD BE WELCOME. && .AVIATION /FOR THE 12Z TAF ISSUANCE/... VFR CONDITIONS ARE EXPECTED THROUGH THE FORECAST PERIOD. WEAK UPR DISTURBANCE MOVING INTO MINNESOTA MAY TRIGGER ISOLD SHRA/TSRA THIS AFTN AT KSAW ALONG LK BREEZE IN VCNTY...BUT ONLY PUT A CB IN CLOUD GROUP TO COVER THIS. LATER TONIGHT...A COLD FRONT IS FCST TO MOVE ACROSS THE AREA. NOT QUITE CLEAR IF SHRA/TSRA WILL AFFECT KCMX OR KSAW. DOES SEEM LIKE THERE IS SOME RISK BASED ON A WEST-EAST LOW-LEVEL JET OVR THE AREA ALONG WITH SOME MOISTURE ADVECTION AT 5-10 KFT. KEPT CIGS VFR AND VSBY UNRESTRICTED BUT DID MENTION SHRA WITH A CB IN CLOUD GROUP. LATER SHIFTS CAN REFINE TO EITHER ADD TSRA IF IT STILL LOOKS WARRANTED OR TO TAKE IT OUT ALL TOGETHER IF IT LOOKS LIKE SHRA/TSRA WILL NOT AFFECT THE TAF SITES. && .MARINE /FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE/... WINDS SHOULD REMAIN AT OR BELOW 25 KTS THROUGH THE FORECAST PERIOD. HIGH PRESSURE WILL BE IN CONTROL...EXCEPT FOR WHEN LOW PRESSURE TROUGHS PASS OVER THE AREA LATE TONIGHT INTO SUNDAY MORNING...THEN AGAIN ON TUESDAY. SCATTERED THUNDERSTORMS MAY OCCUR AS THESE TROUGHS MOVE THROUGH. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE. LAKE SUPERIOR... NONE. LAKE MICHIGAN...
