What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jul 5, 1:04 AM EDT, 3 hours 41 minutes earlier.

Area forecast discussion, Jul 5, 1:04 AM EDT, 3 hours 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
104 AM EDT THU JUL 5 2012

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 336 PM EDT WED JUL 4 2012

PRETTY TRICKY FORECAST ON TAP FOR THE NEXT 12 TO 18 HOURS.  WEAK
FRONT THAT SAGGED THROUGH THE REGION YESTERDAY EVENING AND
OVERNIGHT HAS BECOME STATIONARY OVER NORTHERN WI AND IS NOW SLOWLY
LIFTING BACK NORTHWARD AS A WARM FRONT. THIS FRONT STRETCHED BACK TO
THE WEST TO AN AREA OF LOW PRESSURE NEAR THE ND/MN LINE. AN MCS HAS
DEVELOPED OVER NW MN WHICH CONTINUES TO PUSH EASTWARD ACROSS NRN MN.
THIS MCS IS THE BIG CHALLENGE FOR THE OVERNIGHT FORECAST AS MODEL
DEPICTION AND FORECAST EVOLUTION OF IT HAVE NOT BEEN VERY GOOD. WITH
SURFACE RIDGE AXIS STILL EXTENDING INTO THE EASTERN U.P...AIRMASS IS
DRIER AND MORE STABLE THE FURTHER EAST YOU GO.  STRONG INSTABILITY
GRADIENT EXISTS NEAR THE WI LINE EXTENDING BACK INTO NE MN INVOF THE
THE WARM FRONT. OVERALL STEERING FLOW AND CORFIDI VECTORS SUGGEST THE
MCS SHOULD CONTINUE EASTWARD TO LAKE SUPERIOR AND THEN TRACK A
LITTLE SOUTH OF DUE EAST. MCS SHOULD BEGIN TO DISSIPATE AS IT MOVES
INTO STABLE ENVIRONMENT OVER LAKE SUPERIOR.  HOWEVER...TIMING WOULD
PUT THE REMNANTS ACROSS WESTERN AND CENTRAL SECTIONS IN THE 00Z-04Z
RANGE...WHICH COULD IMPACT SOME EVENING FIREWORKS DISPLAYS.

REMNANTS OF MCS WILL CONTINUE TO DISSIPATE AS IT PUSHES EASTWARD
INTO THURSDAY MORNING AHEAD OF FRONTAL BOUNDARY/SURFACE TROUGH.
DRIER LOW LEVEL AIR WILL BEGIN TO PUSH INTO WESTERN AREAS DURING THE
DAY ON THURSDAY.  WILL KEEP LOW CHANCE POPS ACROSS THE CENTRAL AND
EAST THROUGH THE MORNING UNTIL THE TROUGH CLEARS THE AREA. DESPITE
THE WIND SHIFT TO THE WEST AND NORTHWEST AND WILL BE ANOTHER HOT DAY
ON THURSDAY WITH HIGHS AROUND 90 AWAY FROM THE LAKES.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 336 PM EDT WED JUL 4 2012

BY 00Z FRIDAY THE LARGE 500MB RIDGE WILL BECOME SUPPRESSED...AS THE
500MB LOW SWINGS ACROSS THE S HUDSON BAY SHORELINE OVERNIGHT. MUCH
OF THE ENERGY WILL REMAIN WRAPPED UP NEAR THIS LOW...AS THE NEARLY
STACKED SYSTEM KEEPS PUSHING THE SFC COLD FRONT FROM JUST E OF THE
CWA AT 00Z FRIDAY TO SE LAKE HURON BY DAYBREAK FRIDAY AS HIGH
PRESSURE NOSES BACK IN AT THE SFC AND ALOFT.

FRIDAY INTO SATURDAY...
EXPECT CLOUDS TO FILTER IN DURING THE DAY FRIDAY AS A WARM FRONT
ATTEMPTS TO NEAR FROM THE SW...ASSISTED BY A SHORTWAVE TROUGH
SWINGING AROUND THE MAIN LOW OVER E HUDSON BAY/W QUEBEC. THERE ARE
SIGNIFICANT SMALL SCALE TIMING AND LOCATION DIFFERENCES WITH THE
04/00Z ECMWF AND CANADIAN ATTEMPTING TO PUSH PRECIP INTO THE
INTERIOR W AND CENTRAL COUNTIES DURING THE DAY/EVENING...WHILE THE
GFS AND NAM SOLUTIONS KEEP EVERYTHING TO OUR SOUTH OR RIGHT ALONG
AND S OF THE WI BORDER. THE 12Z SOLUTIONS CAME IN WITH A BIT MORE
MOISTURE...SO WILL GO WITH HIGH CHANCE TO LOW LIKELY POPS NEAR THE WI
BORDER WITH A QUARTER OF AN INCH OR MORE POSSIBLE FRIDAY NIGHT.
EITHER WAY...ONSHORE NNE WINDS SHOULD KEEP COOLER TEMPS SET UP NEAR
LAKE SUPERIOR /ON THE ORDER OF 5-10 DEGREES COOLER THAN THE HOT TEMPS
EXPECTED THURSDAY/. EVEN IF PRECIP DOES OCCUR...IT SHOULD SLOWLY SINK
TO OUR SE...AS A REINFORCING SFC HIGH SINKS IN FROM S CENTRAL CANADA.

WITH HIGH PRESSURE OVER THE AREA ONCE AGAIN...FROM THE SFC UP...DRY
WEATHER CAN BE FIGURED SATURDAY AFTERNOON THROUGH AT LEAST
WEDNESDAY. THE SFC HIGH WILL SLOWLY PUSH TO OUR S AND END UP ACROSS
THE OHIO VALLEY AND CENTRAL/NORTHERN APPALACHIANS TUESDAY NIGHT. DO
HAVE ISOLATED POPS MAINLY INLAND FROM THE GREAT LAKES WEDNESDAY...BUT
HAVE A LOW CONFIDENCE OF THEM AT THIS POINT.
&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 103 AM EDT THU JUL 5 2012

VFR CONDITIONS SHOULD PREVAIL THRU THE FCST PERIOD AT
KIWD/KCMX/KSAW. THERE IS THE POTENTIAL OF ADDITIONAL SHRA/TSRA
OVERNIGHT/EARLY MORNING AS MODEST LOW-LEVEL JET PUSHES ACROSS THE
AREA AHEAD OF A COLD FRONT. HOWEVER...CONFIDENCE IN
DEVELOPMENT/COVERAGE/PLACEMENT OF ANY ADDITIONAL CONVECTION IS VERY
LOW. WILL BE SOMETHING TO MONITOR. ALTHOUGH EARLIER RAINFALL COULD
LEAD TO SOME RADIATIONAL FOG DEVELOPMENT OVERNIGHT IF SKIES
CLEAR...BOUNDARY LAYER FLOW SHOULD BE STRONG ENOUGH TO PREVENT
OCCURRENCE.
&&

.MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)
ISSUED AT 336 PM EDT WED JUL 4 2012

LIGHT WINDS /LESS THAN 20KTS/ WILL PERSIST ACROSS LAKE SUPERIOR FOR
THE FORESEEABLE FUTURE. WITH LOW LEVEL MOISTURE RETURNING ACROSS THE
LAKE BRIEFLY TONIGHT THERE COULD BE A LITTLE PATCHY FOG.
HOWEVER...IT WILL BE SHORT LIVED AS SURFACE TROUGH PUSHES ACROSS THE
LAKE THURSDAY MORNING.
