NWS Marquette, MI wrote its last area forecast discussion before the first event at Jun 18, 1:52 PM CST, 22 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 352 PM EDT MON JUN 18 2007 .SYNOPSIS... 19Z WATER VAPOR LOOP AND RUC 500MB HEIGHT ANALYSIS SHOWED AN UPPER LEVEL RIDGE AXIS AT 500MB WITH HEIGHTS AOA 580 DAM CENTERED OVER EASTERN ONTARIO WHILE A 544 DAM LOW WAS LOCATED OVER SW MANITOBA. IN THE SW FLOW BETWEEN THESE TWO FEATURES...A SHRTWV WAS LOCATED OVER E CENTRAL MN WHILE A MUCH STRONGER SHRTWV WAS OVER THE EASTERN SOUTH DAKOTA AND WESTERN MN BORDER. HEIGHT FALLS ASSOCIATED WITH THESE SHRTWVS...COMBINED WITH 100MB MLCAPES OF 500-1000 J/KG OVER WI AND UPPER MI AND LITTLE IF ANY CIN...ALONG WITH LOW LEVEL CONVERGENCE ALONG A COLD FRONT IS SUPPORTING A SQUALL LINE STRETCHING FROM JUST NW OF THUNDER BAY ONTARIO...THROUGH SAXON HARBOR WI AND INTO NE IA. A FEW SEGMENTS WITHIN THIS LINE ARE PRODUCING SEVERE CRITERIA WINDS...WITH REPORTS OF TREE AND POWERLINE DAMAGE IN BAYFIELD AND ASHLAND WI. OTHER ISOLATED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED AHEAD OF THE SQUALL LINE OVER WI AND UPPER MI...ALSO DUE TO WEAK CAPPING AND UPPER LEVEL FORCING. TO THE WEST...AN AREA OF ISOLATED SHOWERS AND SPRINKLES EXISTS JUST SOUTH OF THE UPPER LOW OVER NORTH DAKOTA...ALONG WITH WIND GUSTS OF 35 TO 45 KT. THIS AREA OF STRONG WINDS IS ASSOCIATED WITH STRONG COLD ADVECTION (55 AT MINOT AND 62 AT BIS) AND A TIGHT GRADIENT ON THE SOUTH SIDE OF A 988MB LOW OVER LAKE WINNIPEG. ALSO TO NOTE FOR LATER IN THE FCST IS AN UPPER LOW OVER CENTRAL BRITISH COLUMBIA ON THE TOP OF A RIDGE ALONG THE WEST COAST. && .SHORT TERM (TONIGHT AND TUESDAY)... FORECAST CONCERNS INCLUDE THUNDERSTORMS TONIGHT AND WINDY CONDITIONS ON TUESDAY. THE UPPER LOW OVER SW MANITOBA IS PROGGED TO MOVE UP TO JAMES BAY BY 00Z WED...BRINGING THE SHRTWV TROUGH OVER THE DAKOTAS ACROSS THE AREA ON TUESDAY. IN THE MEANTIME...THERE IS VERY GOOD AGREEMENT AMONGST ALL MODELS SHOWING THE SQUALL LINE MAINTAINING ITSELF AS IT PUSHES EASTWARD AHEAD OF THE UPPER TROUGH. THIS SEEMS REASONABLE GIVEN THE INSTABILITY PRESENT DOWNSTREAM AND CONTINUED HEIGHT FALLS. THEREFORE...GOING 100 POPS FOR THE ENTIRE CWA TONIGHT ARE FINE. IN ADDITION...HEAVY RAIN STILL SEEMS LIKELY GIVEN STRONG LOW LEVEL MOISTURE TRANSPORT AND PRECIPITABLE WATER VALUES AS HIGH AS 1.8 INCHES PROGGED IN THE CONVECTION. KDLH RADAR SHOWS A GENERAL 0.75 TO 1.00 INCH ACROSS MUCH OF NW WI INTO WESTERN LAKE SUPERIOR...AND THESE VALUES SHOULD OCCUR ACROSS THE CWA TONIGHT. FLOODING CONCERNS ARE MINIMAL...THOUGH...GIVEN HOW DRY IT HAS BEEN RECENTLY...EVEN AFTER LAST NIGHTS RAIN. SEVERE WIND CONCERNS ARE STILL PRESENT TOO GIVEN 900MB WINDS PROGGED BETWEEN 40 AND 50 KT...THEREFORE SEVERE THUNDERSTORM WATCH REMAINS IN EFFECT FOR THE WEST HALF OF THE U.P.. HAIL NOT TOO MUCH OF A CONCERN GIVEN FREEZING LEVELS AROUND 14000 FT AND 0-6KM SHEAR AROUND 30KT (DOES SUPPORT HEAVY RAIN...THOUGH). IF WE DO END UP WITH SOME SEVERE REPORTS ACROSS THE WEST HALF...THE REST OF THE CWA MAY BE INCLUDED IN A WATCH LATER. A DRY SLOT MOVING IN BEHIND THE LINE WILL END THE PCPN WEST TO EAST BEGINNING IN THE WEST AROUND MID EVENING. SOME CONCERNS EXIST ABOUT FOG DEVELOPMENT...BUT IT APPEARS THAT THERE MIGHT BE ENOUGH WIND TO KEEP THAT FROM OCCURRING. GOING FCST LOWS LOOK REASONABLE GIVEN THE MOIST AIRMASS THAT EVEN STILL EXISTS BEHIND THE FRONT. FOR TUESDAY...WIND BECOMES THE NEXT CONCERN AS COLD AIR ADVECTION KNOCKS 850MB TEMPS DOWN TO BTWN 4C NORTH TO 8C SOUTH BY 18Z TUE. MODELS INDICATE THE SURFACE LOW STAYING FAIRLY CLOSE TO THE UPPER LOW AND LIFTING TOWARDS JAMES BAY. THEREFORE THE GRADIENT SHOULD NOT BE AS TIGHT AS OVER NORTH DAKOTA. NONETHELESS...THERE ARE INDICATIONS OF A PRESSURE RISE AREA CROSSING WESTERN LAKE SUPERIOR...WHICH ISALLOBARIC WOULD HELP OUT THE WINDS. SINCE MODELS DEPICT AT CMX 40 KT AT 1000 FT...MUCH OF THIS SHOULD MIX DOWN GIVEN THE UNSTABLE PROFILE. FOR NOW HELD OFF ON A WIND ADVISORY FOR THE KEWEENAW...SINCE IT IS MARGINAL AT THIS POINT...BUT WILL NEED TO BE LOOKED AT MORE FOR LATER SHIFTS. OTHERWISE...ADDED SOME ISOLATED SHOWERS WITH THE THERMAL TROUGH AND LOW CLOUDS COMING ACROSS. CLEARING IS EXPECTED LATE IN THE DAY AS THE TROUGH MOVES AWAY. ONLY MADE A FEW ADJUSTMENTS TO HIGHS...MAINLY TO WARM UP DOWNSLOPE AREAS ALONG LAKE MICHIGAN A FEW DEGREES. .LONG TERM (TUESDAY NIGHT THROUGH NEXT MONDAY)... RIDGING AND SUBSIDENCE WILL DRY THINGS OUT FOR TUE NIGHT...THEN ATTENTION TURNS TO A SHORTWAVE AND ASSOC 3H JET MAX MOVING ACROSS SRN ONTARIO FOR WED INTO WED NIGHT. NAM AND GFS SHOWING SOMEWHAT AGGRESSIVE MOISTURE RETURN FOR A NW FLOW SHORTWAVE. PWATS FCST TO RISE TO AN INCH OR GREATER BY WED AFTERNOON. HEATING AHEAD OF ASSOC FRONTAL BOUNDARY MODELS INDICATE SEVERAL HUNDRED J/KG OF SBCAPE WITH T/TD OF 76/53. ALTHOUGH AGGRESSIVE MOISTENING IS SOMEWHAT SUSPECT...FCST INSTABILITY BY MODELS WILL WARRANT KEEPING LOW CHC POPS IN FOR SHRA/TSRA ACROSS THE CWA FOR WED. AS FRONTAL BNDRY SAGS FURTHER SE...SCT SHRA WILL GENERALLY END NORTH AND WEST OF A CRYSTAL FALLS-MUNISING LINE BY 00Z THU AND THEN BY MIDNIGHT FOR THE REST OF THE CWA. CONFLUENT FLOW AHEAD OF BROAD 5H RDG BUILDING IN FROM THE WEST WILL PROVIDE FOR DRY WX FROM THU CONTINUING INTO THE WEEKEND. LOOK FOR A GRADUAL WARMING TREND FROM THE 70S INTO THE LOW TO MID 80S TOWARD THE WEEKEND AS 5H HEIGHTS BUILD TO 580-585 DM AND 8H TEMPS RISE TO 16-18C BY LATE SAT INTO SUN. BROUGHT IN A CHC OF SHRA/TSRA INTO WRN LAKE SUPERIOR SUN NIGHT AND THEN INTO THE WRN THIRD COUNTIES BY MON AS GFS ENSEMBLE MEAN AND OPERATIONAL ECMWF INDICATE MID-LVL RDG AXIS WILL MOVE SLIGHTLY E ALLOWING FOR WEAK COLD FRONT TO SAG SE INTO AREA. && .AVIATION (FOR 18Z TAF ISSUANCE)... COLD FRONT OVER EASTERN MN WILL CROSS UPPER MI TONIGHT. SHOWERS AND THUNDERSTORMS CONTINUE ALONG THE FRONT...THOUGH EVEN AHEAD OF THE FRONT...ISOLATED STORMS HAVE FORMED OVER WISCONSIN. SOME OF THESE ISOLATED STORMS MAY IMPACT THE TAF SITES THIS AFTN AS THEY MOVE NE. HOWEVER...BETTER CHANCES FOR STORMS...AS INDICATED BY TEMPO TS IN THE TAFS...ARE ASSOCIATED WITH THOSE ALONG THE COLD FRONT AS IT PUSHES EASTWARD. LOWERED VISIBILITIES EVEN FURTHER GIVEN REPORTS OF 1SM AT DLH. THE POSSIBILITY REMAINS OF THE LOW LEVEL FLOW TURNING BRIEFLY WEST AT KCMX BEHIND THE COLD FRONT...WHICH COULD CAUSE THE CIGS TO DROP MORE THAN CURRENTLY INDICATED DUE TO UPSLOPE. OF CONCERN TOMORROW IS STRONG WINDS AT CMX AS THE GRADIENT TIGHTENS AND STRONG COLD AIR ADVECTION OCCURS. UPSTREAM...GUSTS OF 35-40 WITH EVEN A FEW NEAR 50 KT HAVE BEEN REPORTED ACROSS NORTH DAKOTA. THE 50 KT PROBABLY WILL NOT OCCUR HERE...SINCE THE GRADIENT IS MUCH TIGHTER THERE THAN EXPECTED TOMORROW...BUT 40 KT IS NOT OUT OF THE QUESTION. && .MARINE (FOR THE 4 PM LAKE SUPERIOR FCST ISSUANCE)... GUSTS UP TO 30 KT ARE STILL POSSIBLE THIS EVENING OVER THE EAST HALF OF LAKE SUPERIOR IN THE SOUTHERLY FLOW AHEAD OF THE COLD FRONT. GRAND MARAIS MI HAS ALREADY REPORTED WIND GUSTS OF 32 KT. WINDS WILL KICK UP LATE TONIGHT OVER THE WEST HALF AND ESPECIALLY ON TUE AS THE COLD AIR MOVES IN. MAINTAINED THE GALE FORCE GUSTS TO 35 KT MENTION OVER THE TIP OF THE KEWEENAW WITH THE SPEED CONVERGENCE. 30 KT WINDS ARE LIKELY TOO NEAR STANNARD ROCK...ALSO DUE TO SPEED CONVERGENCE AROUND THE HURON MOUNTAINS. BEYOND TUE...THE WIND FIELD RELAXES TO MOSTLY UNDER 20 KT. THE ONLY ITEM OF INTEREST IS A CLIPPER TYPE SYSTEM CROSSING ONTARIO ON WED WHICH COULD GET THE WINDS BRIEFLY TOWARDS 25 KT WED MORNING IN THE WARM PUSH AHEAD OF IT. && .MQT WATCHES/WARNINGS/ADVISORIES...
