AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
452 PM EDT SUN JUL 17 2011

.SHORT TERM /TONIGHT AND MONDAY/...

A VERY WARM AND HUMID DAY ACROSS THE AREA...WITH AFTERNOON
TEMPERATURES IN THE UPPER 80S AND LOWER 90S IN MANY LOCATIONS AWAY
FROM LK MI BREEZE. WITH TD VALUES IN THE MID-UPPER 70S /VERY
IMPRESSIVE FOR UPPER MI/...HEAT INDICES HAVE RISEN INTO THE LOWER
100S. SELECT LOCATIONS THAT HAVE SEEN TD VALUES RISE TO 80 DEGREES
HAVE HAD INDICES NEAR 110. WITH THIS WARM/MOIST AIR MASS AND STRONG
HEATING...DIURNAL CU HAS DEVELOPED ACROSS MUCH OF THE
REGION...EXCEPT OVER MUCH OF ERN UPPER MI DUE TO THE STABLE EFFECTS
OF THE WIND OFF LK MI. THIS WARM/MOIST AIR HAS LED TO SBCAPE VALUES
APPROACHING 5K J/KG AND MLCAPE AROUND 3K J/KG PER LATEST SPC
MESOSCALE ANALYSIS PAGE. SEEING A FEW HIGHER CLOUD TOPS ON VIS SAT
OVER THE WRN CWA ASSOCIATED WITH THE LK BREEZE...WHICH IS EXPECTED
TO CONTINUE INTO THE EVENING. LATEST OB FROM MQT COAST GUARD AND
BGBM4 STARTING TO SHOW THE LAKE BREEZE TRYING TO DEVELOP FROM MQT
COUNTY EASTWARD AND EXPECT THAT TO BE THE OTHER AREA OF POTENTIAL
DEVELOPMENT HEADING INTO THE EVENING. EVEN WITH THE BEST INSTABILITY
FARTHER W...COULD SEE SOME STRONGER STORMS OVER THE ERN CWA...WHERE
THEY WILL BE AIDED BY THE CONVERGENCE BETWEEN THE LK MI AND SUPERIOR
BREEZES. IF STORMS DEVELOP...0-6KM BULK SHEAR VALUES IN THE 40-50KT
RANGE SHOULD SUPPORT TILTED UPDRAFTS...BUT MUCH OF THE SHEAR IS
UNIDIRECTIONAL. EXPECT DAMAGING WINDS TO BE THE MAIN THREAT FOR THE
AREA IF STORMS DEVELOP...AS DCAPES INCREASE ABOVE 1000J/KG AND
SFC-H700 THETAE DIFF VALUES EXCEED 30. LARGE HAIL WILL ALSO BE A
CONCERN...WITH A FAIRLY FAT CAPE AND DECENT CAPE IN THE -10 TO -30C
LEVEL. BUT WETBULB0 HEIGHTS AROUND 13KFT AND FREEZING LEVEL AOA
14KFT...WILL LIMIT THE POTENTIAL. HEAVY RAIN WILL ALSO BE A
FACTOR...AS PWAT VALUES ARE 1.5-2IN. STORMS THAT FORM ALONG THE LK
BREEZE SHOULD MOVE TO THE SE AROUND 30KTS...BUT AS THEY GET FARTHER
AWAY FROM THE STRONGER WINDS OVER THE N...COULD SEE THE STORMS SLOW
DOWN AS WINDS DECREASE.

ATTENTION FOR TONIGHT THEN TURNS TO UPSTREAM CONVECTION OVER MN AND
FARTHER NW IN ERN ND. THESE THUNDERSTORMS WERE ASSOCIATED WITH THE
WEAK WARM FRONT AND H850-700 WAA PUSHING N ACROSS THE AREA. WITH THE
INSTABILITY AND WAA EXPECTED TO CONTINUE...UNCERTAINTY ARRIVES WITH
WHERE EXACTLY THEY WILL TRACK. MODELS...06Z NAM AND 00Z NCEP WRF
ARW...SHOW MCS DEVELOPING AND SHIFTING SE ACROSS ERN MN AND THROUGH
WI. UKMET AND REGIONAL CANADIAN ON THE OTHERHAND BRING THE MCS
ACROSS THE AREA. LOOKING AT THE FORWARD PROP CORFIDI VECTORS...WHERE
THAT MCS DEVELOPS LARGELY WILL DETERMINE IT/S TRACK. IF IT DEVELOPS
N OF A LINE FROM MINOT TO GRAND FORKS ND /RIGHT WHERE THE SUPERCELL
IS CURRENTLY TRACKING AND CONV DEVELOPING IN MN/...IT WOULD LIKELY
TRACK FARTHER E AND BRUSH THIS AREA. BUT ANY FARTHER S /WHERE THE
SRN HALF OF MN CONV IS LOCATED/ AND THE VECTORS SHOW IT SHIFTING SE
EARLIER AND TRACKING SIMILAR TO PREVIOUSLY MENTIONED MODEL OUTPUT.
THIS TRACK WOULD ALSO RUN THE POTENTIAL MCS ALONG THE STRONGEST
INSTABILITY GRADIENT OVER MN AND INTO WI. AT THIS TIME...WENT WITH
THE IDEA OF IT BRUSHING THE CWA ALONG THE WI BORDER AND HAVE BUMPED
POPS UP TO HIGH CHANCES. WILL LEAVE CHANCES/SLIGHTS ACROSS THE REST
OF THE AREA TONIGHT TO ACCOUNT FOR THE POSSIBILITY OF THE FARTHER N
TRACK. IN ADDITION...COULD SEE SOME STORMS TRY TO FIRE FARTHER N AS
THE SFC TROUGH SLOWLY SAGS ACROSS THE CWA AND AIDED BY MCS OUTFLOW
AND WEAK SHORTWAVE MOVING THROUGH SRN CANADA. TEMPS WILL BE SLOW TO
FALL TONIGHT AND AS THE 70S TD VALUES REMAIN IN PLACE. HAVE FOLLOWED
RAW MODEL GUIDANCE AGAIN TONIGHT...WHICH HAS LOWS IN THE LOWER 70S
AND PRODUCES ANOTHER UNCOMFORTABLE NIGHT. ADDED IN THE MENTION FOG
AGAIN FOR TONIGHT WITH THE HIGH TD VALUES.

AT THIS TIME...EXPECTING TOMORROW MORNING TO BE DRY...WITH
PATCHY/AREAS OF FOG/HZ LINGERING OVER THE AREA. THE LIGHT NRLY FLOW
MAY TRY TO PUSH SOME LOWER VSBYS OVER THE KEWEENAW AND E OF
MARQUETTE...SO WILL NEED TO MONITOR WITH FUTURE SHIFTS. IF SKIES
CLEAR OUT SOME...EXPECT TEMPS AND INSTABILITY TO QUICKLY INCREASE
THROUGH THE MORNING. H850 TEMPS WILL BE A TOUCH COOLER BEHIND THE
WEAK FRONT...AROUND 19-20C...SO EXPECT HIGHS TO RISE INTO THE 80S.
THERE COULD BE A FEW 90S ALONG THE WI BORDER...WHERE H850 TEMPS WILL
NEAR 21C AND THERE WILL LESS LK BREEZE INFLUENCE. WITH TD VALUES
REMAINING IN THE LOWER 70S...WILL ONCE AGAIN BE NEAR HEAT ADVY
CRITERIA NEAR THE WI BORDER. DECIDED TO HOLD OFF ON EXTENDING THE
HEAT ADVISORY...AS LK BREEZES COULD LIMIT THE AREAL COVERAGE OF HEAT
INDICES AROUND 100.

MLCAPE VALUES APPROACH 2-2.5K J/KG TOMORROW...WHICH COMBINED WITH
0-6KM BULK SHEAR AROUND 40-45KTS...CREATES THE POTENTIAL FOR
STRONGER STORMS IF THEY DEVELOP. STORM MOTIONS ARE FASTER
TOMORROW...HEADING SE AROUND 35KTS...SO IT SHOULD LIMIT THE HEAVY
RAIN THREAT. WITH THE FRONT LIKELY STALLING OVER WI AND TRYING TO
SHIFT N...EXPECT BOUNDARIES TO BE PRESENT TO INITIATE
CONVECTION...ESPECIALLY WITH THE AID OF LK BREEZE BOUNDARIES. WILL
LIKELY BE SCATTERED IN NATURE DUE TO THE LIMITED UPPER LVL
FORCING...ALTHOUGH MODELS ARE HINTING AT A WEAK SHORTWAVE MOVING
JUST N OF LK SUPERIOR DURING THE AFTN. THINK BEST CHANCES WILL OCCUR
WHERE THE WINDS OF LK SUPERIOR MEET UP WITH THE LK BREEZE FROM LK
MI. THIS SHOULD BE OVER SCNTRL UPPER MI...WHICH IS ALSO WHERE THE
AXIS OF BEST INSTABILITY/TD VALUES WILL OCCUR. CMX SOUNDING VERY
CAPPED TOMORROW DUE TO THE LIGHT FLOW OFF THE LK AND POSSIBLE LOW
CLOUDS THROUGH THE MORNING...SO HAVE LEFT OUT POPS IN THAT AREA.

.LONG TERM /MON NIGHT THRU SUN/...

MON NIGHT...SLIGHTLY DRIER AIRMASS SETTLES INTO THE AREA. WITH
LIGHT/CALM WINDS...CLEAR/PARTLY CLOUDY SKIES AND PRECIPITABLE WATER
FALLING BACK TOWARD MORE TYPICAL MID JULY VALUES...EXPECT MORE
EFFECTIVE RADIATIONAL COOLING WHICH SHOULD ALLOW TEMPS TO FALL
GENERALLY INTO THE MIDDLE 60S.

HEAT OVER THE PLAINS WILL BEGIN TO BUILD BACK TOWARD UPPER MI TUE AS
WEAK SFC HIGH TO THE NE SHIFTS E. WITH INCREASING WAA AND WEAK COLD
FRONT THAT PASSED MON RETURNING NE AS A WARM FRONT...THERE MAY BE A
RISK OF CONVECTION OVER THE SW PORTION OF THE FCST AREA TUE AFTN...
BUT BETTER POTENTIAL FOR SHRA/TSRA LOOKS TO BE TUE NIGHT AS
LOW-LEVEL JET STRENGTHENS TOWARD THE UPPER MISSISSIPPI VALLEY AND
UPPER GREAT LAKES.

WED THRU SUN...POSITIVE HEIGHT ANOMALIES WITH CNTRL CONUS RIDGE/MID
LEVEL HIGH ARE CURRENTLY PEAKING. AFTER BEING HELD UP BY TROF
AMPLIFYING INTO THE NE CONUS EARLY THIS WEEK...THE RIDGE WILL
GRADUALLY WEAKEN AS IT EXPANDS EASTWARD. BY THE END OF THE WEEK...
THE RIDGE/POSITIVE HEIGHT ANOMALIES WILL EXTEND FROM THE CNTRL
PLAINS TO THE E COAST. EASTWARD EXPANSION OF THE RIDGE WILL ALLOW
THE NRN EDGE OF THE HOT DOME OVER THE CNTRL CONUS TO EXPAND INTO THE
UPPER LAKES AT TIMES. HOWEVER...WITH THE RIDGE WEAKENING SOME...HEAT
ACROSS THE NCNTRL CONUS WILL EASE LATER IN THE WEEK. THE GEFS
SHOWS 850MB TEMP STANDARD DEVIATIONS FALLING UNDER 1 BY THE WEEKEND.
IN THE MEANTIME...THE HOTTEST AIR OF THIS WARM PERIOD MAY OCCUR WED
AHEAD OF A SHORTWAVE TRACKING ACROSS SCNTRL CANADA. 850MB TEMP
STANDARD DEVIATIONS INCREASE TO AROUND 2.5 ACROSS THE FCST AREA PER
GEFS/ECMWF...A LITTLE HIGHER THAN OBSERVED TODAY. LOW/MID 90S SHOULD
BE COMMON ACROSS THE W HALF OF THE FCST AREA WED. COLD FRONT
ASSOCIATED WITH SHORTWAVE SHOULD MOVE ACROSS THE UPPER LAKES THU...
RESULTING IN SLIGHT COOLING. IT WILL BE COOLER FRI...BUT TEMPS WILL
STILL BE ABOVE NORMAL WELL INTO THE 80S. WARMING WILL OCCUR AGAIN
SAT AHEAD OF THE NEXT MORE SIGNIFICANT SHORTWAVE TRACKING ACROSS
SCNTRL CANADA. EXPECT BETTER COOLING SUN BEHIND ASSOCIATED COLD
FRONT. ON MOST DAYS DURING THE WEEK...PRES GRADIENT SHOULD GENERALLY
BE WEAK...ALLOWING FOR SOME LOCAL COOLING AT TIMES NEAR THE GREAT
LAKES. OTHERWISE...THERE REALLY WON'T BE NOTICEABLE RELIEF FROM HIGH
DWPTS/UNCOMFORTABLE HUMIDITY THRU THE WEEK. BEST OPPORTUNITY FOR
MORE SIGNIFICANT LOWERING OF DWPTS AND MORE COMFORTABLE CONDITIONS
WILL PROBABLY BE AT THE VERY END OF THE FCST PERIOD IN THE WAKE OF
THE WEEKEND COLD FRONT. AS FOR PCPN...PATTERN SUPPORTS POTENTIAL FOR
ROUNDS OF TSTMS...POSSIBLY SVR...SINCE UPPER MI WILL BE ON THE EDGE
OF FASTER WESTERLY FLOW ALOFT AND ALSO WITHIN THE INSTABILITY
GRADIENT WITH VERY STRONG INSTABILITY JUST TO THE SW OR W. ALTHOUGH
CAPPING MAY PREVENT DEVELOPMENT OVER UPPER MI WED (700MB TEMPS
12-14C)...THERE IS ALWAYS THE POSSIBILITY OF CONVECTION TO THE NW
AND N PEELING SE TOWARD GREATER INSTABILITY. WEAK COLD FRONT
ASSOCIATED WITH PASSING WAVE TO THE N SHOULD MOVE ACROSS THE UPPER
LAKES THU...PROVIDING A CONTINUED CHC OF SHRA/TSRA. MAINTAINED LOW
POPS FRI WITH START OF WAA AHEAD OF NEXT SYSTEM AND THEN SAT
WITH APPROACHING COLD FRONT. WILL SHOOT FOR DRY WEATHER FOR THE
NEW DAY 7 (SUN) WITH ASSUMPTION COLD FRONT WILL BE E OF THE AREA.

&&

.AVIATION /FOR THE 18Z TAF ISSUANCE/...

HOT MUGGY CONDITIONS TODAY...ALONG WITH FAIR AMOUNTS OF INSTABILITY
AND DIFFERENTIAL HEATING...SHOULD BE ENOUGH TO SPAWN SOME SHOWERS
AND THUNDERSTORMS THIS AFTERNOON AND EVENING. THE UNCERTAINTY LIES
IN TIMING AND LOCATION. AS LAKE BREEZE COMES THROUGH SAW...THIS MAY
PROVIDE THE LIFT NEEDED TO INITIATE CONVECTION IN THE VCNTY. AS A
RESULT HAVE INCLUDED VCSH AT SAW 20Z ALONG WITH WIND SHIFT. ALSO...A
MCS CURRENTLY IN NORTH DAKOTA SHOULD START TRACKING SOUTHEAST
OVERNIGHT. MODELS HAVE THE SYSTEM TRACKING JUST TO OUR SOUTH...SO
HAVE CHOSEN TO LEAVE OUT OF FORECAST UNLESS THE TRACK CHANGES.

THE OTHER MAIN CONCERN THIS PERIOD IS THE FOG...ESPECIALLY AT
CMX...DUE TO ALREADY MOIST AIR...LIGHT WINDS...AND POSSIBLE
AFTERNOON PRECIP. A FAVORABLE NORTHEAST WIND DIRECTION AT CMX
OVERNIGHT COULD CAUSE FOG CURRENTLY LOCATED OVER THE WESTERN LAKE TO
COME ONSHORE...SO LIFR SEEMS TO BE PRETTY CERTAIN. CHOSE TO GO MORE
CONSERVATIVE ON VISIBILITY FOR SAW AS WINDS ARE LIGHTER AND MORE
VARIABLE...BUT LIFR OR EVEN VLIFR IS STILL A POSSIBILITY.

&&

.MARINE /FOR THE 4PM LAKE SUPERIOR FORECAST ISSUANCE/...

WINDS WILL REMAIN BELOW 20KTS THROUGH THE PERIOD...WITH A NEARLY
STAGNANT PRESSURE PATTERN INFLUENCING THE REGION. AREAS OF FOG WILL
BE POSSIBLE FOR MUCH OF THE PERIOD...AS WARM AND MOIST AIR MOVES
NORTHEAST ACROSS LAKE SUPERIOR. HAVE EXPANDED THE DENSE FOG ADVY FOR
THE REST OF THE OPEN WATER ZONES THROUGH MON AFTN. THIS ADVISORY
WILL LIKELY NEED TO EXTEND INTO THE MIDDLE OF THE WORK WEEK AS WINDS
WEAKEN AND THERE IS LITTLE RELIEF FROM THE WARM/MOIST AIR.
