The episode as NWS MQT wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
159 AM EDT SUN JUL 7 2013
.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 413 PM EDT SAT JUL 6 2013
A LITTLE MORE SUNSHINE THAN WAS EARLIER EXPECTED HAS ALLOWED FOR
ANOTHER VERY WARM DAY ACROSS UPPER MICHIGAN WITH TEMPERATURES
SIMILAR TO WHERE THEY WERE YESTERDAY IN THE MID/UPPER 80S. WEAK
SURFACE TROUGH/FRONT CONTINUES TO SAG VERY SLOWLY SOUTHWARD OUT OF
ONTARIO INTO LAKE SUPERIOR. WEAK SHORTWAVE AS SEEN IN WV IMAGERY
MOVING EASTWARD ACROSS MN HELPING TO PRODUCE A SCATTERING OF
SHOWERS AND SOME THUNDERSTORMS ACROSS NORTHEAST MN AND THE
ARROWHEAD. AS THIS WAVE MOVES EASTWARD...SCATTERED SHOWERS AND
THUNDERSTORMS WILL DEVELOP/MOVE INTO WESTERN LAKE SUPERIOR AND
PORTIONS OF WESTERN UPPER MICHIGAN. DESPITE THE WARM AIRMASS
INSTABILITY NOT ALL THAT IMPRESSIVE AND SHEAR IS LIMITED SO DO NOT
ANTICIPATE ANYTHING MORE THAN A FEW DOWNPOURS WITH ANY STORM THIS
AFTERNOON/EVENING.
AS RAINFALL CURRENTLY OVER THE ARROWHEAD MOVES ACROSS THE LAKE WOULD
NOT BE SURPRISED TO SEE THE SURFACE TROUGH SURGE SOUTHWARD...WITH THE
TROUGH DRAPING ITSELF EAST TO WEST ACROSS LAKE SUPERIOR AND THE
KEWEENAW TONIGHT. STILL SOME DISCREPANCY ON HOW FAR SOUTH THE SURFACE
TROUGH MAKES IT TONIGHT SO WILL HAVE TO KEEP AN EYE ON IT. DEPENDING
ON THE EXTENT OF THE EAST SOUTHEASTERLY WINDS INTO THE KEWEENAW
OVERNIGHT COULD SEE SOME FOG DEVELOP THERE. AS THE WEAK SHORTWAVE
MOVES ACROSS LAKE SUPERIOR THIS EVENING...THE CHANCE OF RAIN SHOULD
DIMINISH SOME FOR THE OVERNIGHT PERIOD.
STRONGER SHORTWAVE MOVING ACROSS THE NORTHERN PLAINS SHOULD HELP AID
IN THE DEVELOPMENT OF ANOTHER CLUSTER OF SHOWERS AND THUNDERSTORMS
ACROSS ND TONIGHT WHICH SHOULD THEN PUSH EAST-SOUTHEASTWARD
OVERNIGHT. AS THIS MAIN SHORTWAVE MOVES ACROSS UPPER MICHIGAN ON
SUNDAY EXPECT A SCATTERING OF SHOWERS AND A FEW THUNDERSTORMS TO
DEVELOP ACROSS THE AREA. ONCE AGAIN LIMITED INSTABILITY AND SHEAR
SHOULD LIMIT THE THUNDER INTENSITY. WITH MORE CLOUD COVER AROUND ON
SUNDAY...TEMPERATURES WILL BE SEVERAL DEGREES LOWER THAN TODAYS. AS
SHORTWAVE EXITS THE AREA...SURFACE TROUGH SHOULD BEGIN MOVING SOUTH
OF TE AREA LATE IN THE DAY ENDING THE RAIN CHANCE FROM NORTHWEST TO
SOUTHEAST.
.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 413 PM EDT SAT JUL 6 2013
A GENERALLY ACTIVE PATTERN WILL CONTINUE FOR UPPER MI THROUGH THE
UPCOMING WEEK AS IMPULSES TRACK EAST ON AN INCREASINGLY ZONAL FLOW
BEFORE RIDGING DEVELOPS AND BUILDS IN FROM THE WEST BY NEXT WEEKEND.
THE BEST CHANCE FOR PRECIPITATION CONTINUES TO BE TUESDAY NIGHT
THROUGH WEDNESDAY MORNING.
SUNDAY NIGHT...THE MID-LEVEL LOW THAT HAS BEEN STUBBORN TO DEPART
THE MID-MISSISSIPPI VALLEY WILL FINALLY BE EXITING INTO THE
NORTHEASTERN STATES BY THE END OF THE WEEKEND. A TRAILING COLD FRONT
THAT WILL BE RESPONSIBLE FOR PRECIP DURING THE DAY SUNDAY WILL
CONTINUE TO PUSH SOUTHEAST...CLEARING THE CWA BY DAYBREAK MONDAY.
SOME PATCHY FOG IS POSSIBLE ACROSS MUCH OF INTERIOR UPPER
MI...ESPECIALLY WEST...AS MID AND UPPER-LEVEL CLOUDS BEGIN TO DEPART
WITH WEAK MID-LEVEL RIDGING BUILDING INTO THE AREA. NW UPSLOPE
FAVORED AREAS ACROSS THE WEST AND KEWEENAW COULD SEE SOME PATCHY
DRIZZLE AS WELL.
MONDAY AND MONDAY NIGHT...SEVERAL MODELS ARE AGGRESSIVE AT KEEPING
PLENTY OF LOW-LEVEL MOISTURE TRAPPED UNDER INCREASING SUBSIDENCE
FROM THE MID-LEVEL RIDGE. GIVEN THE AMOUNT OF INSOLATION THIS TIME
OF YEAR...LOW CLOUDS SHOULD ERODE THROUGHOUT THE DAY ONCE MIXING
BEGINS TO TAP INTO DRIER AIR IN THE INVERSION LAYER. THE LOCAL WRF
APPEARS TO BE HANDLING THIS TREND WELL...SO WENT WITH IT FOR SKY
COVER AND TEMPS. FOCUS THEN TURNS TO POSSIBLE ISOLATED SHOWERS AND
STORMS IN THE AFTERNOON. THERE IS A HINT THAT MLCAPE VALUES COULD
SURPASS 500 J/KG...EVEN IN THE MODELS THAT DO NOT HAVE HIGHER SFC
DEW POINTS. THIS WOULD BE ENOUGH TO ASSIST ANY CUMULUS THAT CAN
BREAK THE INVERSION AND RESULT IN SOME ISOLATED SHOWERS AND STORMS.
WITH MINIMAL MID TO UPPER-LEVEL SUPPORT...ANY FOCUS SHOULD BE NEAR
LAKE BREEZE CONVERGENCE AREAS. WITH LIGHT NW FLOW...PLACED SMALL
AFTERNOON POPS ALONG LAKE SUPERIOR ACROSS THE WEST HALF...AND LAKE
MICHIGAN IN THE EAST HALF WHERE THE TWO LAKE BREEZES CONVERGE.
THE GFS AND ECMWF ARE BOTH HINTING AT LIGHT PRECIPITATION DEVELOPING
WITH WEAK WAA MONDAY NIGHT AHEAD OF LOW PRESSURE ORGANIZING IN THE
NORTHERN PLAINS. H8 THROUGH H7 MOISTURE TRANSPORT WILL REMAIN MOST
PRONOUNCED ACROSS SOUTHERN MN AND SOUTHERN WI ON THE NOSE OF A 40KT
WIND SPEED MAX. THIS IS WHERE THE SURFACE FRONT WILL HAVE
STALLED...SO THINKING IS THAT MOST IF NOT ALL PRECIP WILL BE FOCUSED
ALONG THAT FRONTAL BOUNDARY. MUCH OF THE MODELED PRECIP IS ACTUALLY
A RESULT OF FOG FROM INCREASING SFC MOISTURE AHEAD OF THE
APPROACHING SYSTEM. WILL THEREFORE KEEP POPS OUT FOR MONDAY NIGHT.
TUESDAY NIGHT AND WEDNESDAY...A STRONG SHORTWAVE TROUGH CURRENTLY IN
THE GULF OF ALASKA IS PROGGED TO TRACK EAST ALONG THE U.S. AND
CANADIAN BORDER. MODELS ARE IN GOOD AGREEMENT THAT THE TROUGH WILL
BE STRONGEST AND BECOME SLIGHTLY NEGATIVELY TILTED AS IT PUSHES OVER
THE UPPER MS VALLEY. ALSO...THE GFS SOLUTION HAS BECOME
PROGRESSIVELY STRONGER WITH EACH RUN OVER THE PAST DAY. GIVEN
SUBSTANTIAL MID-LEVEL Q-VECTOR CONVERGENCE...APPRECIABLE MOISTURE
TRANSPORT...AND MUCAPE APPROACHING 1000 J/KG...HAVE BUMPED UP PRECIP
WORDING TO LIKELY SHOWERS AND THUNDERSTORM ACROSS THE WEST TUESDAY
NIGHT. HOWEVER...HAVE KEPT ONLY CHANCE WORDING FOR THE REST OF THE
AREA AS THE BEST FORCING SURGES NORTHEAST TO NORTH OF LAKE SUPERIOR.
A FEW SHOWERS AND THUNDERSTORMS COULD LINGER WEDNESDAY MORNING AS
FORCING CONTINUES TO DEPART THE REGION.
WEDNESDAY NIGHT THROUGH SATURDAY...BOTH THE GFS AND ECMWF ARE IN
AGREEMENT THAT THE MAIN TROUGH WILL TRACK NORTHEAST OUT OF THE
AREA...BUT DISAGREE ON HOW QUICK THIS WILL HAPPEN. THE ECMWF SLOWS
THE TROUGH MUCH MORE THAN THE GFS AND KEEPS SOME LIGHT SHOWERS
ROTATING AROUND THE BACKSIDE ACROSS THE EASTERN CWA AND EASTERN LAKE
SUPERIOR. A STRONG RIDGE BUILDING IN FROM THE WEST SHOULD BE ENOUGH
TO MOVE THE TROUGH ALONG TO THE EAST...SO AM NOT TOO CONFIDENT THAT
THE SHOWERS WILL LINGER AROUND ALL THE WAY THROUGH THURSDAY.
THEREFORE...KEPT ONLY SLIGHT CHANCES OF PRECIP INTO THURSDAY. FOR
FRIDAY AND SATURDAY...THE RIDGE WILL WORK EASTWARD OVER THE CWA AND
BRING DRY CONDITIONS AND MOSTLY SUNNY SKIES.

LIKELY TO FOLLOW THE FROPA THIS EVNG WITH DIURNAL COOLING AND

.MARINE...(FOR THE 10 PM LAKE SUPERIOR FORECAST ISSUANCE)
ISSUED AT 930 PM EDT SAT JUL 6 2013
GIVEN SHIP OBSERVATION OF ZERO VISIBILITY OVER WESTERN LAKE SUPERIOR
AND VERY HUMID AIRMASS OVER CHILLY WATER FOLLOWING SOME SHOWERS...
OPTED TO ISSUE DENSE FOG ADVISORY FOR THE WEST HALF OF LAKE SUPERIOR
THROUGH SUNDAY MORNING. SOME DRYING ON SUNDAY AFTERNOON FOLLOWING A
COLD FRONTAL PASSAGE SHOULD DISSIPATE THE THICKEST FOG.
PREVIOUS DISCUSSION ISSUED AT 413 PM EDT SAT JUL 6 2013
WINDS WILL REMAIN BELOW 15 KT ACROSS LAKE SUPERIOR THROUGH TUESDAY
AS A WEAK SURFACE TROUGH DROPS SOUTHWARD ACROSS THE LAKE FOLLOWED BY
AN AREA OF HIGH PRESSURE. WITH SCATTERED SHOWERS AND THUNDERSTORMS
EXPECTED THIS AFTERNOON THROUGH SUNDAY...AREAS OF FOG WILL CONTINUE
ACROSS THE LAKE. AS ANOTHER LOW DEVELOPS OVER THE PLAINS ON TUESDAY
AND APPROACHES LAKE SUPERIOR ON WEDNESDAY....NORTHWESTERLY WINDS OF
15 TO 25 KNOTS WILL BE POSSIBLE BEHIND FOR A TIME WEDNESDAY AND
WEDNESDAY NIGHT. SURFACE HIGH MOVING OVER THE UPPER LAKES LATE IN
THE WEEK WILL ALLOW LIGHT WINDS TO RETURN.
