AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
133 AM EDT MON JUN 2 2014
.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 403 PM EDT SUN JUN 1 2014
THE HRRR LOOKS TO HAVE A PRETTY GOOD HANDLE ON THE GENERAL HANDLING
OF THE SHOWERS AND THUNDERSTORMS THROUGH AROUND 03Z. SHOWERS AND
THUNDERSTORMS CONTINUE TO GENERATE ACROSS THE E HALF OF WI...WHERE
THEY HAD FEWER CLOUDS /INCREASED DAYTIME INSTABILITY/. MLCAPES
AROUND 500-1500 J/KG ARE ABUNDANT IN THIS AREA...AND AS EXPECTED
SIGNIFICANTLY DROP OFF AWAY FROM CENTRAL UPPER MI.
GENERALLY 0.25 TO 0.5 IN OF PRECIP HAS ALREADY FALLEN OVER THE W
HALF OF UPPER MI. PW VALUES WILL REMAIN 180-220 PERCENT OF NORMAL
THROUGH MONDAY AFTERNOON...OR 1.6 TO 1.8IN. HEAVY RAIN WILL CONTINUE
TO BE THE MAIN THREAT OR ANY STRONGER SHOWERS OR THUNDERSTORMS THAT
SLIDE INTO THE CWA. STRONG WINDS HAVE ALSO BEEN REPORTED IN
WI...AROUND 45MPH. WILL CONTINUE TO MONITOR FOR THE POTENTIAL FOR A
FEW STRONGER STORMS IN OUR AREA WHERE THE SHEAR IS A BIT
STRONGER...EVEN THROUGH INSTABILITY LIMITED OVERALL DUE TO MORE
ABUNDANT CLOUD COVER.
ON THE OPPOSITE END OF THE WEATHER SPECTRUM...WE CONTINUE TO MONITOR
FAR E UPPER MI...WHERE WINDS HAVE GENERALLY BEEN 10-15KTS...TEMPS
HAVE ROSE NEAR 80F INLAND FROM LAKE MI AND LAKE HURON...AND HUMIDITY
VALUES ARE FALLING TO NEAR 30 PERCENT /MAINLY AT RACO/. THE WILDFIRE
POTENTIAL STATEMENT WILL BE ALLOWED TO EXPIRE AT 20Z...AND WAS TAKEN
OFF THE TOP NEWS EARLIER TODAY. SHOWERS CONTINUE TO NEAR THIS
AREA...BUT DRY AIR NEAR THE SFC IS KEEPING MUCH IF ANYTHING FROM
ACCUMULATING. LOOK FOR IMPROVING FIRE WEATHER CONDITIONS THROUGH THE
EVENING HOURS...NOT ONLY AS A FEW SHOWERS MAKE IT INTO THE
AREA...BUT TEMPERATURES FALL INTO THE MID 50S.
THE COLD FRONT TO OUR W WILL SLOWLY SLIDE SE OVER THE UPPER GREAT
LAKES REGION AT 12Z MONDAY...LIKELY AROUND SE LAKE SUPERIOR/E UPPER
MI. THERE MAY BE A FEW LINGERING SHOWERS/THUNDERSTORMS ALONG THE
FRONT EARLY IN THE MORNING...BUT WOULD EXPECT THEM TO LARGELY BE
SHIFTING AWAY FROM THE AREA. THE UPPER TROUGH AND ASSOCIATED
SHORTWAVES WILL BE LIFTING NORTHEAST MONDAY MORNING...STRENGTHENING
THE SURFACE LOW MOVING THROUGH THE UPPER GREAT LAKES REGION LATE
MONDAY AFTERNOON INTO MONDAY EVENING. TEMPERATURES WILL TOP OUT IN
THE MID 70S OVER THE W HALF...AND LIKELY FAR E UPPER MI ON MONDAY.
LOOK FOR MUCH OF THE THUNDERSTORM ACTIVITY TO RESIDE OF THE W HALF
OF UPPER MI THROUGH 18Z /NO SIGNIFICANT CHANGE THERE FROM THE
PREVIOUS FCST/...BEFORE EXPANDING E THROUGH THE REST OF THE
AFTERNOON.
.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 433 PM EDT SUN JUN 1 2014
AFTER MID/UPPER LEVEL TROF MOVES ACROSS THE GREAT LAKES REGION OVER
THE NEXT FEW DAYS...MID/UPPER LEVEL RIDGING WILL REDEVELOP INTO THE
GREAT LAKES REGION DURING THE MID AND LATE WEEK PERIOD. OVER THE
UPCOMING WEEKEND...FCST WILL HINGE UPON HOW FAST THE RIDGE BREAKS
DOWN OR HOW FAST IT IS FORCED E BY NEXT TROF MOVING ACROSS W AND
CNTRL NAMERICA. THIS PATTERN FAVORS WET WEATHER HERE OVER THE NEXT
COUPLE OF DAYS AS TROF MOVES INTO THE AREA...THEN DRY WEATHER MID
AND LATE WEEK AS APPROACHING MID/UPPER RIDGE SUPPORTS SFC HIGH PRES
RIDGING S FROM HUDSON BAY INTO THE GREAT LAKES REGION...A TYPICAL
SPRING/EARLY SUMMER PATTERN AS ICE FILLED HUDSON BAY AND THE CHILLY
GREAT LAKES ENHANCE SFC HIGH PRES DEVELOPMENT. IN THIS TYPE OF
PATTERN...TEMPS THIS WEEK SHOULD NOT STRAY TOO FAR FROM EARLY JUNE
NORMALS...BUT THE MAJORITY OF DAYS WILL PROBABLY HAVE TEMPS SOMEWHAT
ON THE COOL SIDE OF NORMAL WITH THE COOLEST WEATHER IN THE MIDWEEK
PERIOD.
BEGINNING MON NIGHT...SFC LOW PRES WILL LIKELY TRACK ACROSS WRN LAKE
SUPERIOR OR PERHAPS FAR WRN UPPER MI AND THEN ON INTO NRN ONTARIO BY
TUE MORNING. BEST CHC OF SHRA/TSRA WILL BE IN THE EVENING...BUT WILL
BE DIMINISHING FROM SW TO NE AS SHORTWAVE/COLD FRONT SWEEP ACROSS
THE AREA AND MIDLEVEL DRYING ARRIVES. THIS DRYING IS MORE PRONOUNCED
OVER THE E HALF OF THE FCST AREA. AS HAS BEEN THE CASE THE LAST FEW
DAYS...MODELS SHOW ADDITIONAL SHORTWAVE ENERGY OVER THE DAKOTAS/MN
MON AFTN MOVING INTO UPPER MI EARLY TUE MORNING. THIS WAVE WILL HELP
MAINTAIN DEEPER MOISTURE OVER THE W MON NIGHT. ALONG WITH APPROACH
OF THE ASSOCIATED SECONDARY COLD FRONT/SFC TROF...SOME SHRA WILL
LIKELY LINGER THRU THE NIGHT OVER THE W. AS THE SECONDARY COLD FRONT
SWEEPS E ALONG WITH DEEPER MOISTURE...SHRA CHANCES WILL SPREAD E TUE
MORNING. DAYTIME HEATING MAY FURTHER AID EXPANSION OF SHRA TUE OVER
THE E. NOT OUT OF THE QUESTION THAT THERE COULD BE SOME THUNDER OVER
THE E...DEPENDING ON HOW MUCH HEATING OCCURS EARLY IN THE DAY.
HOWEVER...WITH ALMOST NO MLCAPE INDICATED...WILL LEAVE THUNDER
MENTION OUT. BULK OF DEEP LAYER FORCING WITH THE SHORTWAVE PASSES BY
JUST N OF UPPER MI...SO STEADIER RAIN SHOULD PASS BY TO THE N.
HOWEVER...THE KEWEENAW MAY GET BRUSHED BY THE MORE PERSISTENT SHRA
TUE MORNING AND INTO THE EARLY AFTN WHICH WOULD LEAD TO A
CHILLY/MISERABLE AT LEAST FIRST HALF OF THE DAY DUE TO THE RAIN AND
BRISK WNW WINDS OFF COLD LAKE SUPERIOR. FOG THAT WILL BE EXPANDING
AND BECOMING MORE DENSE OVER LAKE SUPERIOR TONIGHT/MON AND PROBABLY
DEVELOPING ON NRN LAKE MICHIGAN AS WELL WILL AFFECT LOCATIONS NEAR
THE LAKES WHENEVER WINDS ARE ONSHORE. THE FOG WILL CLEAR OFF THE
LAKES TUE.
LINGERING SHRA SHOULD END FROM SW TO NE TUE AFTN AND TUE NIGHT AS
MID/UPPER TROF SLOWLY EDGES E. WHILE DRY WEATHER IS EXPECTED TO
SETTLE INTO THE AREA FOR WED/THU AS MID/UPPER RIDGE APPROACHES...
HAVE SOME CONCERN THAT THERE COULD BE MORE CLOUDS AND PERHAPS SOME
-SHRA/SPRINKLES AT SOME POINT LATER WED/EARLY THU DUE TO ONE LAST
SHORTWAVE DROPPING INTO THE DEPARTING TROF. THE ECMWF IS STRONGEST
WITH THIS FEATURE...FOLLOWED BY THE GEM. THE GFS IS WEAKEST AND
SHOWS NO IMPACT FROM SHORTWAVE. WITH THE 12Z ECMWF BACKING OFF ON
THIS WAVE...WILL MAINTAIN A DRY/PARTLY CLOUDY FCST. ALSO...CONCERNS
IN THE LAST COUPLE OF DAYS WITH SHORTWAVES TRACKING E ACROSS THE
CNTRL CONUS AND BRINGING A SHRA THREAT TO THE FCST AREA ARE
BASICALLY GONE NOW AS MODELS GENERALLY SHOW DEPARTING
TROF/APPROACHING RIDGE SUPPRESSING SHORTWAVES. OTHERWISE...GRADIENT
NRLY WIND DUE TO HIGH PRES BUILDING S FROM NRN MANITOBA/HUDSON
BAY/NRN ONTARIO WILL LEAD A CHILLY DAY NEAR LAKE SUPERIOR ON WED.
EXPECT 50S NEAR THE LAKE WITH MANY LAKESIDE LOCATIONS PROBABLY
HOLDING IN THE 40S FOR MUCH OF THE DAY. WELL IN THE INTERIOR...
EXPECT 60S TO LWR 70S. TEMPS ON THU SHOULD BE SIMILAR TO WED WITH
LITTLE CHANGE IN WINDS. OPTED TO LOWER MIN TEMPS TOWARD THE LOW SIDE
OF BIAS CORRECTED GUIDANCE FOR WED NIGHT AND THU NIGHT UNDER DRY AIR
MASS. THU NIGHT WILL LIKELY BE THE COLDEST NIGHT WITH HIGH PRES
RIDGE OVERHEAD. TRADIATIONAL COLD SPOTS MIGHT SLIP INTO THE UPPER
30S.
AS ALLUDED TO EARLIER...FCST FOR FRI THRU THE WEEKEND WILL DEPEND ON
HOW QUICKLY THE NEXT TROF MOVING ACROSS W AND CNTRL NAMERICA CAN
EITHER PUSH RIDGE EASTWARD OR SUPPRESS IT. USUALLY THERE IS A BIAS
TO BREAK DOWN RIDGES TOO QUICKLY IN THE LONGER RANGE...SO PLAN TO
LEAN TOWARD THE SLOWER SOLUTION WHICH HAS BEEN REPRESENTED BY THE
ECMWF FOR THE LAST FEW MODEL RUNS. AS A RESULT...EXPECT DRY WEATHER
TO LINGER FRI/SAT AS DRY AIR CONTINUES TO DOMINATE IN ASSOCIATION
WITH SFC HIGH PRES RIDGING S FROM HUDSON BAY INTO THE GREAT LAKES.
THAT SAID...THERE ARE INDICATIONS OF A STRONG SHORTWAVE LIFTING NE
TO HUDSON BAY. TRAILING...DECAYING COLD FRONT ASSOCIATED WITH WAVE
MAY BRING SOME -SHRA INTO WRN UPPER MI AS EARLY AS LATE FRI. WILL BE
SOMETHING TO LOOK FOR IN LATER MODEL RUNS. OTHERWISE...WILL
INTRODUCE CHC POPS FOR SUN AS IT APPEARS TROF WILL FORCE RIDGE
EASTWARD. CONDITIONS WILL BECOME A LITTLE WARMER FRI/SAT...BUT
OVERALL...RIGHT AROUND NORMAL FOR EARLY JUNE.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT)
ISSUED AT 133 AM EDT MON JUN 2 2014
LIGHT WINDS AND FOG/STRATUS WILL OCCUR AT ALL TAF SITES OVERNIGHT
WITH CONDITIONS DETERIORATING FROM VFR DOWN TO MVFR AT KIWD... LIFR
CONDITIONS AT KSAW AND VLIFR CONDITIONS EXPECTED AT KCMX. EXPECT THE
MAIN LOW OVER THE E MN/W WI BORDER AT DAYBREAK MONDAY TO PUSH INTO W
LAKE SUPERIOR BY 18Z MONDAY WITH RAIN SHOWERS SPREADING FROM WEST TO
EAST THROUGH THE MORNING AND AFTERNOON HRS. EXPECT SLOWLY IMPROVING
CONDITIONS AT ALL SITES IN THE AFTERNOON TO VFR.

.MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)
ISSUED AT 213 PM EDT SUN JUN 1 2014
WINDS OUTSIDE OF ANY THUNDERSTORMS WILL REMAIN LESS THAN 30KTS
THROUGH THE PERIOD. OTHER THAN A CHANCE OF THUNDERSTORMS LINGERING
INTO TUESDAY NIGHT...FOG WILL BE THE MAIN THREAT WITH THE
SIGNIFICANT MOISTURE THAT HAS OVERSPREAD THE AREA. LIGHTER WINDS
OVERNIGHT WILL HELP MUCH OF LAKE SUPERIOR FALL BELOW 3MI VIS THROUGH
MONDAY MORNING OVER THE W HALF LAKE SUPERIOR...AND THROUGH MUCH OF
THE DAY ACROSS THE E HALF. A MARINE DENSE FOG ADVISORY MAY BE ISSUED.
A TROUGH OF LOW PRESSURE OVER MN WILL SLOWLY DRIFT ACROSS W LAKE
SUPERIOR THIS EVENING. THE TROUGH WILL DEEPEN TONIGHT AS A LOW LIFTS
NORTHEAST FROM THE CENTRAL PLAINS AND CROSSES LAKE SUPERIOR MONDAY
EVENING THROUGH TUESDAY MORNING. EXPECT THE LOW TO EXIT ACROSS S
JAMES BAY TUESDAY AFTERNOON. THIS WILL ALLOW A HIGH ACROSS W HUDSON
BAY TO SLOWLY SINK ACROSS ONTARIO WEDNESDAY AND THURSDAY...WITH A
RIDGE SLOWLY BUILDING ACROSS LAKE SUPERIOR THROUGH FRIDAY.
