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 May 30, 2:34 PM CST, 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 434 PM EDT THU MAY 30 2013 .SHORT TERM...(THIS EVENING THROUGH FRIDAY) ISSUED AT 430 PM EDT THU MAY 30 2013 UPPER FLOW FEATURES LARGE UPPER LOW OVER ROCKIES WITH RIDGING OVER MID ATLANTIC. S/SW FLOW ALOFT HAS ALLOWED WARM FRONT TO SLIDE TO NORTH OF UPR MICHIGAN OVER LK SUPERIOR. VIS SATELLITE SHOWS CU FIELD OVER WEST HALF OF UPR MICHIGAN WHILE SKIES ARE CLEAR IN STABLE LAYER OFF LK MICHIGAN ACROSS EASTERN CWA. HAVE THE WARMEST DAY OF THE YEAR SO FAR WITH MANY AREAS AT OR ABOVE 80 DEGREES. HUMIDITY TO GO ALONG WITH THE WARMTH AS DWPNTS ARE MAINLY IN THE 60S. INSTABILITY EXTENDS INTO WI AND LOWER MICHIGAN. WV LOOP/RADAR LOOP SHOWS SHORTWAVE THAT CAME OUT OF IA THIS MORNING HAS TRIGGERED CLUSTERS OF SHRA/TSRA OVER MUCH OF WI AND THESE ARE DRIFTING TOWARD UPR MICHIGAN AS MEAN WINDS ARE MORE SOUTHERLY. TSRA ARE NOW AS CLOSE AS VCNTY IWD...BUT ALONG REST OF WI BORDER ARE STILL 1-2 HOURS AWAY. THUS FAR...ISOLD SVR REPORTS HAVE OCCURRED UPSTREAM IN WISCONSIN WHERE THERE IS A TORNADO WATCH IN EFFECT. SHORTWAVE OVER WISCONSIN LIFTS NORTH THIS EVENING. EXPECT CLUSTER OF SHRA/TSRA TO IMPACT WI BORDER OF UPR MICHIGAN THROUGH 00Z...THEN AS H85-H7 WINDS VEER MORE SW...EXPECT AT LEAST SCT SHRA/TSRA TO SLIDE ACROSS REST OF WEST HALF OF CWA THROUGH 04Z AS THIS AREA WILL BE ON THE NOSE OF THE GREATEST H85 MOISTURE TRANSPORT AND THERE ARE MULTIPLE COMPLEXES OF SHRA/TSRA UPSTREAM OF INITIAL CONVECTION ALL THE WAY BACK INTO MO/IL. WILL CARRY LIKELY POPS MUCH OF THE EVENING OVER THE WEST HALF OF CWA...WITH LESSER CHANCES OVER THE EAST AS THAT AREA IS FARTHER AWAY FROM TRACK OF PRIMARY SHORTWAVE/MOISTURE TRANSPORT. CONCERNING SEVERE POTENTIAL...WILL HAVE TO WATCH WI BORDER THROUGH THIS EVENING AS THERE IS DECENT 0-1KM SHEAR UP TO 30 KTS AND THIS AREA IS IN AREA OF HIGHER DCAPE AND 1000-850MB LAPSE RATES ARE OVER 9C/KM. 0-6KM DEEP LAYER SHEAR IS LACKING THUS FAR AS DIFFERENCE BTWN H85 AND H5 WINDS IS MINIMAL SO STORM ORGANIZATION IS SCATTERED UPSTREAM. STILL THERE ARE HINTS ON RADAR THAT STORMS MAY BE TRYING TO GET BETTER ORGANIZED IN THIS ENVIRONMENT SFC BASED CAPES OVER 2000J/KG. SINCE FORWARD PROPAGATING CORFIDI VECTORS ARE AIMED INTO SCNTRL UPR MICHIGAN...CANNOT RULE OUT LINE SEGMENT TSRA PRODUCING GUSTY WINDS THROUGH 02Z FOR THE WI BORDER/SCNTRL UPR MICHIGAN. PLAN IS FOR SHRA/TSRA TO DIMINISH AFTER MIDNIGHT FOR ALL BUT SCNTRL CWA AS H85-H7 MOISTURE TRANSPORT FOCUSES MORE OVER WI INTO LOWER MICHIGAN. SEVERE POTENTIAL OVERNIGHT SEEMS LESS AS MUCAPE IS ONLY FORECAST TO BE LESS THAN 500J/KG AS AIRMASS MAY BE PRETTY WORKED OVER FROM EVENING CONVECTION. CONFIDENCE IN DEGREE OF INSTABILITY OVERNIGHT IS ON THE LOWER SIDE THOUGH. ONE LAST ITEM FOR LATER TONIGHT IS DENSE FOG POSSIBLE ALONG LK MICHIGAN. VIS SATELLITE HAS SHOWN EXPANSION OF FOG OVER LK MICHIGAN AND WEB CAMS FROM TIP OF DOOR PENINSULA HAVE SHOWN LOWERING OF VSBY. RETAINED THEME OF GOING FORECAST FOR FRIDAY AS INITIALLY DOES APPEAR FOCUS FOR MORE ORGANIZED SHRA/TSRA WILL BE EAST AND SOUTH OF UPR MICHIGAN ON NOSE OF LOW-LEVEL JET. APPROACHING SHORTWAVE IN THE AFTN ALONG WITH BUILDING INSTABILITY /MLCAPES NEARING 1500J/KG/ SUPPORT POSSIBLE REDEVELOPMENT OF SHRA/TSRA IN THE AFTN. TEMPS LIKELY A TOUCH COOLER THAN TODAY IN MOST AREAS...THOUGH WILL PROBABLY BE WARMER OVER THE KEWEENAW AS WARM FRONT WILL BE TO THE NORTH. TEMPS MOST AREAS ON FRIDAY STILL WILL STILL BE IN AT LEAST THE LOWER 80S. WILL BE ANOTHER HUMID DAY AS WELL WITH DWPNTS STAYING AROUND 60F INTO THE 60S. .LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY) ISSUED AT 430 PM EDT THU MAY 30 2013 FRI NIGHT...NAM SNDGS INDICATE MLCAPE VALUES RISING INTO THE 500-1300 J/KG RANGE BY 00Z SAT OVER THE WRN CWA ALONG AXIS OF MID TO UPPER 50S SFC DEWPOINTS AND 8H THETA-E MAXIMUM. EXPECT SOME ISOLD/SCT CONVECTION TO FIRE FRI AFTN OVER THE WRN PORTION OF THE CWA AND THEN SPREAD INTO CENTRAL CWA DURING THE EVENING HRS. DEEP LAYER SHEAR INCREASES TO 30-40KT BY EVENING SO ISOLD SVR STORMS COULD OCCUR IF THE HIGHER RANGE OF MLCAPE IS REALIZED. THE E HALF WILL BE MORE STABLE WITH MODIFIED AIR OFF LAKE MI UNDER SRLY FLOW...SO EXPECT ONLY ISOLD SHRA COVERAGE THERE FRI EVENING. BETTER CHCS FOR SHRA/TSRA COULD SHIFT INTO THE ERN FCST AREA LATER FRI EVENING AS INSTABILITY AXIS SHIFTS E. HOWEVER...PCPN CHANCES SHOULD OVERALL DIMINISH DURING THE OVERNIGHT HRS AS INSTABILITY WANES AND MID-LVL DRYING OCCURS. AXIS OF MID/UPPER TROF WILL REACH THE UPPER MISSISSIPPI VALLEY SAT AND WILL USHER IN COOLER WEATHER FOR THE FCST AREA. PCPN CHCS WILL CONTINUE SAT WITH TROF STILL W OF THE AREA. HOWEVER...HEAVIER/MORE WIDESPREAD PCPN SHOULD REMAIN SE OF THE AREA (OVER LWR MI) WHERE HIGHER THETA-E AND MOISTURE/INSTABILITY AXIS WILL BE LOCATED. THERE IS STILL A POTENTIAL FOR THUNDER...MAINLY OVER THE SOUTH CENTRAL AND ERN FCST AREA...WHERE MOISTURE CONVERGENCE AND INSTABILITY ALONG LINGERING FRONTAL BOUNDARY COULD BE ENHANCED BY DEVELOPING LAKE BREEZES. PER GFS/GEM/ECMWF SOLNS DEPICTING A SLOWER EASTWARD PROGRESSION OF THE MID-LVL TROF ACROSS THE FCST AREA HAVE DECIDED TO LEAVE SHRA CHCS IN THROUGH AT LEAST SUN MORNING UNTIL DEEPER MOISTURE DEPARTS LATER IN THE AFTERNOON WITH EXITING TROF AXIS. SUNDAY WILL TURN CHILLY AS GFS/GEM/ECMWF SHOW 850MB TEMPS FALLING TO 0-2C BY LATE AFTERNOON. IF CLOUDS/PCPN LINGER THRU THE DAY...IT WILL BE QUITE CHILLY WITH TEMPS ACROSS THE N HOLDING ONLY IN THE LOW/MID 40S. FOG WILL CONTINUE TO IMPACT LAKE SUPERIOR/NRN LAKE MI OVER THE NEXT COUPLE OF DAYS. WHERE WINDS ARE ONSHORE...MARINE FOG WILL AFFECT LAKESIDE LOCATIONS. WITH SRLY WINDS...LAKESIDE LOCATIONS NEAR LAKE MICHIGAN WILL BE MOST AFFECTED FRI. FOG WILL TEND TO SPREAD INLAND FRI NIGHT. PORTIONS OF THE WRN LAKE SUPERIOR SHORELINE INCLUDING THE KEWEENAW SHOULD BE AFFECTED AS WELL AS WINDS BECOME ONSHORE LATE FRI NIGHT. FOG MAY BE DENSE AT TIMES CLOSE TO THE LAKE. AS WINDS CONTINUE TO SHIFT N SAT/SAT NIGHT...FOG WILL CLEAR OUT OF NRN LAKE MI WHILE FOG MOVES ONSHORE NEAR LAKE SUPERIOR. ANY LINGERING FOG SHOULD FINALLY DISSIPATE FROM LAKE SUPERIOR ON SUN AS COOLER DRIER AIR WORKS ACROSS THE LAKE. WITH SFC HIGH PRES PUSHING INTO THE AREA AND A DRY AIR MASS...SUN NIGHT COULD BE QUITE COOL ESPECIALLY OVER THE WRN INTERIOR WHICH WILL BE CLOSER TO THE ARRIVING HIGH PRES RDG AXIS. WILL CONTINUE A MENTION OF PATCHY FROST OVER THESE AREAS. HIGH PRES THEN SETTLES OVER THE UPPER LAKES ON MON...PROVIDING A SUNNY BUT COOL DAY. FROST IS A DEFINITE POSSIBILITY AGAIN MON NIGHT...ACROSS THE MUCH OF THE INTERIOR CWA AS SFC HIGH PRES WILL STILL BE PARKED OVER THE AREA. ON TUE...NEXT TROF WILL BE LIFTING THROUGH THE NRN PLAINS/SCNTRL CANADA. A FEW OF THE 12Z MODELS STILL HAVE SOME SHRA ARRIVING OVER THE FAR WRN CWA LATE TUE AFTN AHEAD OF THIS SHORTWAVE TROUGH SO WILL KEEP IN SOME SLIGHT CHC POPS THERE. ALTHOUGH AS NOTED ON PREV DISCUSSION...PREVAILING SE FLOW AHEAD OF THE SHORTWAVE SHOULD HELP MAINTAIN LOW-LEVEL DRY AIR AND WILL LIKELY SLOW PROGRESSION OF PCPN EASTWARD. PCPN CHCS SHOULD INCREASE FROM WED INTO THU AS MODELS CONSISTENTLY SHOW MID-LVL TROF AXIS MOVING CLOSER TO THE UPPER GREAT LAKES. BEST INSTABILITY WILL STAY SOUTH OF THE CWA WED INTO THU SO NO THUNDERSTORMS ARE EXPECTED. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON) ISSUED AT 149 PM EDT THU MAY 30 2013 SHOWERS AND THUNDERSTORMS ARE DEVELOPING OVER SOUTHERN WISCONSIN. EXPECT THESE SHRA/TSRA TO LIFT INTO WESTERN UPPER MICHIGAN ON NOSE OF LOW-LEVEL JET THIS AFTN THEN ACROSS REST OF UPPER MICHIGAN THIS EVENING. GIVEN DEGREE OF WARM AND HUMID AIR OVERHEAD...ISOLD STORMS ARE POSSIBLE LATE THIS AFTN INTO THE EVENING HOURS MAINLY AT IWD OR SAW. GUSTY WINDS ARE THE PRIMARY HAZARD. GENERALLY EXPECT MVFR CONDITIONS AS THE SHRA/TSRA SLIDE ACROSS. SOME FOG MAY FORM LATER TONIGHT BUT THERE WILL BE ENOUGH WIND IN LOWER LEVELS TO KEEP IT FROM BECOMING TOO DENSE. CONDITIONS SHOULD BE MAINLY QUIET ON FRIDAY MORNING AS MOST OF THE SHOWERS AND STORMS WILL BE EAST OF THE AREA. PLAN ON DECREASING CLOUDS WITH STEADY SOUTH WINDS. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 430 PM EDT THU MAY 30 2013 WITH GENERALLY WEAK PRES GRADIENT AND STABLE CONDITIONS OVER LAKE SUPERIOR...EXPECT WINDS TO BE UNDER 25KT THRU THE WEEK. WIDESPREAD FOG IS LIKELY...ESPECIALLY AFTER RAINFALL OCCURS OVER THE LAKE. BEST SHOT OF DENSE FOG LATER TONIGHT WILL BE OVER EASTERN LK SUPERIOR. PATCHY DENSE FOG IS LIKELY TO CONTINUE THROUGH SAT. HIGH PRESSURE WILL MOVE INTO THE AREA SUNDAY NIGHT AND REMAIN OVERHEAD THROUGH TUESDAY NIGHT...KEEPING WINDS LESS THAN 25 KNOTS. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE. LAKE SUPERIOR... NONE. LAKE MICHIGAN... DENSE FOG ADVISORY UNTIL 6 PM EDT FRIDAY FOR LMZ248-250. && SHORT TERM...JLA LONG TERM...VOSS AVIATION...JLA MARINE...JLA
