AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
451 PM EDT MON JUL 18 2011

.SYNOPSIS...
WV IMAGERY AND RUC ANALYSIS INDICATED MID/UPPER LEVEL HIGH CENTERED
OVER NE/KS WITH A RIDGE EXTENDING NORTHWARD INTO SASK RESULTING IN
WNW FLOW THROUGH THE UPPER GREAT LAKES. ONLY VERY WEAK IF ANY
SHORTWAVE FEATURES ARE APPARENT IMMEDIATELY UPSTREAM. FARTHER
WEST...A SHRTWV WAS MOVING INTO ERN NORTH DAKOTA. AT THE SFC...A
WEAK FRONT EXTENDED FROM WRN UPPER MI INTO WRN WI AND SW MN. TO THE
EAST...THE FRONT WAS ILL-DEFINED WITH THE LAKE BREEZE BOUNDARIES
DOMINATING. STRONG CONVECTION HAD DEVELOPED JUST SOUTH OF THE WI
BORDER ALONG THE MLCAPE GRADIENT AND ALSO WHERE A DIFFERENTIAL
HEATING BOUNDARY FROM EARLIER CLOUD AREA MAY LINGERED INTO THE
AFTERNOON AND WAS SLIDING TO THE ESE.
&&

.SHORT TERM...TONIGHT AND TUESDAY
EXPECT THE NRN WI CONVECTION TO REMAIN MAINLY SOUTH OF THE
BORDER...PERHAPS CLIPPING THE SRN PORTION OF MENOMINEE COUNTY. SOME
SHOWERS HAVE STRUGGLED TO DEVELOP ON OR JUST NORTH OF THE LAKE
SUPERIOR BREEZE BOUNDARY BUT HAVE BEEN SHORT-LIVED AND WEAK.
HOWEVER...SOME ISOLD SHRA/TSRA WILL REMAIN POSSIBLE GIVEN THE HIGH
MLCAPE VALUES OVER INLAND UPPER MI. HOWEVER...THE STRONGER
CONVECTION TO THE SOUTH SHOULD LIMIT POTENTIAL FOR TSRA OVER S CNTRL
UPPER MI.

WEAK HIGH PRES BUILDING INTO THE REGION OVERNIGHT AND INTO TUESDAY
WITH SUBSIDENCE/QVECTOR DIV WILL SHRA/TSRA OUT OF THE REGION. ENOUGH
WEAK DRY ADVECTION WILL LOWER DEWPOINTS AND MIN TEMPS INTO THE MID
60S. 850 MB TEMPS AROUND 20C SHOULD STILL ALLOW MAX READINGS TO
CLIMB NEAR 90 INLAND WITH UPPER 70S AND LOWER 80S NEAR THE GREAT
LAKES WHERE LAKE BREEZES WILL DEVELOP.

.LONG TERM /TUES NIGHT THROUGH NEXT MONDAY/...

STRONG UPPER RIDGE REMAINS IN CONTROL AT THE START OF THE PERIOD.
APPEARS THAT THERE WILL BE A SHORTWAVE RUNNING ACROSS THE TOP OF THE
RIDGE AND SE ACROSS THE CWA ON TUES NIGHT. AS THIS OCCURS...WARM
FRONT ASSOCIATED WITH A LOW IN THE NRN PLAINS AND SRN CANADA WILL
LIFT N ACROSS THE AREA. VERY STRONG WAA FROM H850-500 SHOULD LEAD TO
CONVECTION ACROSS THE AREA...WITH THE QUESTION BEING IF IT WILL
DEVELOP NEAR US ALONG THE WARM FROM OR IF THERE WILL BE AN MCS FROM
CONVECTION NEAR THE TRIPLE POINT IN NW MN. DECENT ELEVATED CAPE
VALUES...APPROACHING 1.5-2.5K J/KG UNDER INCREASING MID LVL LAPSE
RATES. EFFECTIVE BULK SHEAR LOOKS TO BE AROUND 30-35KTS WHICH SHOULD
SUPPORT SOME TILTING OF THE UPDRAFT. HEAVY RAIN WILL LIKELY BE
ASSOCIATED WITH THE STORMS WITH THE HIGH PWAT VALUES...NEAR
2IN...BUT STRONG WINDS /IF BECOMES SFC BASED/...AND HAIL ARE ALSO
POSSIBLE. WIND WILL BE ESPECIALLY POSSIBLE IF THE UPSTREAM STORMS
EXPECTED IN NW MN EVOLVE INTO AN MCS...AS FORWARD PROP CORFIDI
VECTORS WOULD PULL IT ESE ACROSS THE CWA AND RIGHT ALONG THE BEST
INSTABILITY GRADIENT /STRETCHING FROM NW MN TO THE U.P. AND WI
BORDER/.

UPPER RIDGE AXIS BEGINS TO PUSH ACROSS THE AREA ON WED...AS THE WARM
FRONT CONTINUES TO PUSH N ACROSS THE CWA. THIS SHOULD HELP KEEP
POTENTIAL CONVECTION FARTHER TO THE N ACROSS SRN CANADA AS WEAK
WAVES RUN THROUGH THE RIDGE...ESPECIALLY INTO WED AFTN. MODELS
SHOWING BEST FORCING ACROSS NRN LK SUPERIOR AS THE THERMAL RIDGE
SLIDES INTO THE WRN CWA. WILL CONTINUE THE HIGHEST POPS OVER NRN LK
SUPERIOR...BUT CONTINUED SOME CHANCES IN THE MORNING FOR POSSIBLE
LINGERING CONVECTION UNTIL THE WARM FRONT MOVES FAR ENOUGH N.
TAPERED THEM OFF OVER THE LAND AREAS TO SLIGHTS DURING THE AFTN...AS
THE STRONG WAA SHOULD CAP THE ATMO. WED WILL LIKELY BE THE WARMEST
DAY OF THIS HEAT WAVE...WITH H850 TEMPS RISING TOWARDS 24C BEHIND
THE WARM FRONT. WITH DECREASING CLOUDS BEHIND THE FRONT DURING THE
LATE MORNING AND INTO THE AFTN...EXPECT HIGHS TO RISE INTO THE MID
90S OVER MANY LOCATIONS AWAY FROM THE COOLING INFLUENCE OF LK MI. SW
WINDS SHOULD BE STRONG ENOUGH TO LIMIT ANY LK SUPERIOR BREEZES FOR
MUCH OF THE DAY...SO EXPECT LOCATIONS NEAR LK SUPERIOR TO BE AS WARM
AS INLAND. TD VALUES WILL ALSO BE BACK IN THE 70S...WHICH WILL
CREATE HEAT INDEX VALUES ABOVE 100 DEGREES. CONSIDERED EXCESSIVE
HEAT WATCH FOR WED...AS HEAT INDEX VALUES SHOULD BE NEAR THE 105
WARNING CRITERIA. OPTED TO REISSUE THE SPS DISCUSSING THE DANGEROUS
CONDITIONS ON WED AND WILL LET ANOTHER SHIFT FINE TUNE THE VALUES.

ATTENTION THEN TURNS TO COLD FRONT QUICKLY SHIFTING THROUGH THE AREA
WED NIGHT INTO THURS MORN. SHORTWAVE FROM THE UPPER TROUGH CURRENTLY
OVER THE WRN CONUS LOOKS TO RUN JUST N OF THE CWA WED NIGHT INTO
THURS MORN...BUT STILL SEE REASONABLE HEIGHT FALLS ACROSS THE AREA
IN THE MORNING. WITH BEST FORCING AND MOISTURE MAINLY N OF THE
AREA...KEPT THE HIGHEST POPS OVER NRN LK SUPERIOR AND THEN SWEPT LOW
CHANCE POPS ACROSS THE LAND AREA DURING THE OVERNIGHT HRS WITH THE
CURRENT FRONT TIMING. HAVE TRIMMED BACK POPS TO JUST THE MORNING
HOURS BASED ON THE DRY AIR AND SUBSIDENCE SHOWN ON ALL OF THE MODELS
BEHIND THE FRONT. WITH PARTLY/MOSTLY SUNNY SKIES...EXPECT TEMPS TO
STILL BE ABOVE NORMAL AS H850 TEMPS ARE AROUND 18C. THIS SHOULD
PRODUCE HIGHS IN THE UPPER 80S TO AROUND 90. HAVE LOWERED TD VALUES
FROM WHAT WE HAD GOING ON THURS BASED OF THE LATEST TIMING IN THE
MODELS. THIS SHOULD PRODUCE MUCH LOWER HEAT INDEX VALUES FOR
THURSDAY...UPPER 80S AND LOWER 90S.   THEREFORE...WILL BACK OFF SOME
ON THE DANGEROUS HEAT CONDITIONS MENTION IN THE SPS FOR THURS AFTN.

DAYS 4 THROUGH 7 /THURS NIGHT THROUGH NEXT MONDAY/...

THURS NIGHT AND FRI...WITH THE COLD FRONT EXITING THE AREA.
UNCERTAINTY COMES FROM HOW QUICKLY RETURN FLOW TRIES TO AFFECT THE
AREA. SOME HINTS AT A WEAK SHORTWAVE MOVING NE AROUND THE UPPER
RIDGE AND ACROSS THE CWA ON THE 00Z ECMWF/GEM. ELEVATED INSTABILITY
LOOKS TO INCREASE UNDER THE SW FLOW AND WAA LATE THURS NIGHT AND
INTO THE DAY ON FRI. PREVIOUS SHIFT HAD A GOOD HANDLE ON THE POPS
ALONG THE BORDER FOR THURS NIGHT AND THEN THE HIGHEST POPS ALONG THE
SW HALF OF THE CWA ON FRI. ONLY MADE MINOR TWEAKS TO PUSH THE CHANCE
POPS A LITTLE FARTHER NE TO ACCOUNT FOR WAA AND INSTABILITY
MOVEMENT. WILL NOTE THAT THE 06/12Z GFS KEEPS WAA FARTHER SW AND
PUSHES A WEAK HIGH ACROSS THE AREA...WHICH COULD LEAD TO DRY WX.
LATE ARRIVING 12Z ECMWF CONTINUED THIS TREND...SO THE NEXT SHIFT
WILL NEED TO MONITOR FOR ADJUSTMENTS. HOT CONDITIONS SHOULD REMAIN
OVER THE AREA ON FRIDAY...AS H850 TEMPS RISE TOWARDS 19C...PRODUCING
HIGHS IN THE 80S.

DETERMINISTIC AND ENSEMBLE MEMBERS OF THE 00Z ECMWF/GFS/GEM ALL
HINTING AT A STRONGER WAVE EJECTING OUT OF THE W COAST TROUGH AND
BREAKING DOWN THE RIDGE THAT HAS BEEN OVER THE AREA OVER THE LAST
WEEK. THIS...COMBINED WITH THE COLD FRONT EXPECTED TO SWEEP THROUGH
THE AREA...SHOULD LEAD TO TEMPERATURES FALLING BACK TO MORE NORMAL
VALUES FOR THE SECOND HALF OF THE WEEKEND AND THE BEGINNING OF NEXT
WEEK. THERE IS SOME UNCERTAINTY IN THE TIMING OF THE TROUGH AND
FRONT...WHICH IS TO BE EXPECTED GIVEN THE STRENGTH OF THE RIDGE THAT
HAS IN PLACE. THEREFORE...WILL HAVE THE FRONT STARTING TO MOVE
ACROSS THE AREA FROM W TO E ON SAT INTO SAT NIGHT. THERE ARE SOME
HINTS AT IT LINGERING INTO SUN...SO DID ADD CHANCES OVER THE EAST
FOR THE POSSIBLE SLOWER PASSAGE. A WEAK HIGH PRESSURE RIDGE IS THEN
EXPECTED TO SLIDE OVER THE SUN NIGHT AND INTO MONDAY BEHIND THE
SECONDARY COLD FRONT MOVING THROUGH.
&&

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

EXPECT VFR CONDITIONS THROUGH THIS EVENING WITH THE BEST CHANCE FOR
CONVECTION REMAINING SOUTH OF KSAW. LATE TONIGHT...ENOUGH LOW LEVEL
MOISTURE WILL STILL LINGER FOR FOG POTENTIAL. ANY FOG SHOULD
DISSIPATE BY AROUND 12Z.
&&

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

A HIGH PRESSURE RIDGE OVER THE UPPER GREAT LAKES WILL KEEP WINDS
BELOW 20KTS THROUGH TUESDAY. SOUTHWEST TO WEST WINDS COULD INCREASE TO
25 KTS WED NIGHT INTO THURSDAY OVER WRN AND CENTRAL LAKE SUPERIOR AS
THE GRADIENT TIGHTENS BETWEEN ADVANCING TROUGH OVER ONTARIO AND THE NRN
PLAINS AND RIDGE DEPARTING TO THE EAST. ANOTHER RIDGE BUILDING IN
BEHIND THE TROUGH FOR THU NIGHT AND FRIDAY WILL BRING WINDS BACK
DOWN BLO 20 KTS. AREAS OF FOG WILL BE POSSIBLE FOR MUCH OF THE
PERIOD...AS WARM AND MOIST AIR MOVES NORTHEAST ACROSS LAKE SUPERIOR.
&&

UPPER MICHIGAN...
NONE.
LAKE SUPERIOR...
  DENSE FOG ADVISORY UNTIL 8 AM EDT TUESDAY FOR LSZ264>267.

...HEAT AND HUMIDITY TO CONTINUE THROUGH WEDNESDAY...

HIGH TEMPERATURES WILL REMAIN IN THE UPPER 80S TO MID 90S ACROSS
INTERIOR PORTIONS OF WESTERN UPPER MICHIGAN THROUGH WEDNESDAY.
HUMIDITY VALUES ARE EXPECTED TO BE SLIGHTLY LOWER ON TUESDAY...WHICH
WILL KEEP HEAT INDEX VALUES IN THE LOW TO MID 90S. A WARM FRONT
PUSHING THROUGH THE AREA ON TUESDAY NIGHT WILL BRING A RE-ENFORCING
SURGE OF WARM MOIST AIR INTO THE REGION FOR WEDNESDAY. AT THIS
POINT...WEDNESDAY AFTERNOON LOOKS TO BE THE MOST DANGEROUS...WITH
HEAT INDEX VALUES RISING TO 100 TO 105 DEGREES AWAY FROM THE
MODERATING INFLUENCE OF LAKE MICHIGAN. A COLD FRONT SLIDING THROUGH
UPPER MICHIGAN ON WEDNESDAY NIGHT WILL BRING SLIGHTLY DRIER AIR AND
COOLER TEMPERATURES TO THE AREA ON THURSDAY. THIS SHOULD KEEP HEAT
INDEX VALUES FROM EXCEEDING 90 DEGREES.

THE HEAT AND HUMIDITY MAY ONCE AGAIN PRODUCE DANGEROUS CONDITIONS FOR
THOSE WHO ARE WORKING OR PLAYING OUTDOORS. THOSE WHO DO NOT HAVE AIR
CONDITIONING IN THEIR RESIDENCES MAY ALSO BE AT RISK...PARTICULARLY
YOUNG CHILDREN...ELDERLY PEOPLE...OR THOSE WITH RESPIRATORY PROBLEMS.
