NWS Marquette, MI wrote its last area forecast discussion before the first event at Jun 12, 7:30 PM EST, 2 hours earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MARQUETTE MI 830 PM EDT THU JUN 12 2008 UPDATED FOR THE 00Z AVIATION DISCUSSION .DISCUSSION... .SHORT TERM (TONIGHT AND FRIDAY)... OVERNIGHT TONIGHT...THE SOUTHEASTERN CWA HAS BEEN PLACED IN THE MODERATE AREA FOR EXCESSIVE HEAVY RAINFALL. RAINFALL ESTIMATES FROM THE RADAR HAVE NOT BEEN TOO IMPRESSIVE THUS FAR...WITH THE MOST RAIN FALLING ALONG A THIN LINE FROM BIG BAY DE NOC ACROSS SOUTHEASTERN DELTA COUNTY TO JUST EAST OF STEUBEN IN SCHOOLCRAFT COUNTY. ESTIMATES HAVE BEEN BETWEEN AN INCH AND AN INCH AND A HALF. NO CHANGE HAS BEEN OBSERVED AT THE MANISTIQUE (MANISTIQUE RIVER) OR NAHMA JUNCTION (STURGEON RIVER) GAUGES...AS THEY WERE MAINLY UPSTREAM OR NOT QUITE IN THE CORRECT BASIN WITH THE HEAVIEST RAINFALL. ANYWAY...THE NEXT ROUND OF MODERATE TO HEAVY RAIN SEEMS TO BE DEVELOPING OVER CENTRAL WISCONSIN...MOVING NORTH-NORTHEAST AROUND 35 TO 40 MPH. SINCE THE U.P. HAS NOT RECEIVED HIGHER PRECIPITATION AMOUNTS AS OF LATE...FFG IS GENERALLY AROUND 3 TO 4 INCHES IN 6 HOURS...2.5 TO 4 INCHES IN 3 HOURS...AND 2 TO 3.5 INCHES IN AN HOUR. MODEL GUIDANCE FOR AFTERNOON HIGH TEMPERATURES HAVE ONCE AGAIN BEEN 5 TO 10 DEGREES TOO HIGH. TAKING THIS INTO ACCOUNT...WILL SIGNIFICANTLY UNDERCUT HIGH TEMPERATURES FOR FRIDAY AFTERNOON. EVEN THOUGH MANY WOULD REALLY APPRECIATE MID TO UPPER 70S...UPPER 60S TO LOWER 70S SEEM MORE REALISTIC. THIS MAY BE THE BEST THING TO DO CONSIDERING 850MB TEMPERATURES ACTUALLY FALL FROM ABOUT 15C TO 14C AS THE SFC LOW NEARS FROM THE WEST. THE ONE THING THAT COULD SIGNIFICANTLY THROW A WRENCH INTO THE TEMPERATURE FORECAST WILL BE SKY CONDITIONS. THE SURFACE LOW...CURRENTLY OVER SOUTHEASTERN SASKATCHEWAN WILL SHIFT NORTHEASTWARD TO EASTERN MANITOBA AND WEST CENTRAL ONTARIO BY 18Z FRIDAY. THIS SHOULD LEAVE CENTRAL AND EASTERN UPPER MICHIGAN IN THE DRY SLOT. THE POTENTIAL FOR CONVECTION WILL REMAIN IN THE DRY SLOT...WHERE SURFACE HEATING SHOULD CAUSE INSTABILITY IN THE COLD AIRMASS. THE FREEZING LEVELS SHOULD FALL FROM AROUND 13 KFT TODAY TO AROUND 11 KFT BY FRIDAY AFTERNOON. WITH CONVECTIVE TEMPERATURES RUNNING RIGHT AROUND 70F...THE AMOUNT AND TIMING OF CLOUD COVER WILL BE CRUCIAL. AT CMX...IT WILL BE DIFFICULT TO BREAK THE DEEP INVERSION THAT HAS SET UP. THE NAM SHOWS AN EVEN STRONGER CAP THAN THE GFS THAT WILL NEED TO BE OVERCOME FOR CONVECTION. && .LONG TERM (FRIDAY NIGHT THROUGH THURSDAY)... 500 MB TROUGH REMAINS ACROSS THE AREA WITH THE TROUGH AXIS TO THE WEST 00Z SAT WITH THE TROUGH AXIS MOVING THROUGH SAT MORNING. UPPER GREAT LAKES THEN STAY IN A BROAD 500 MB TROUGH THROUGH SUN WITH THE NAM SHOWING ANOTHER SHORTWAVE MOVING IN SUN EVENING. NAM SHOWS SOME 850-500 MB Q-VECTOR CONVERGENCE MOVING OUT OF THE CWA FRI NIGHT WITH MOISTURE AND Q-VECTOR CONVERGENCE RETURNING SAT AFTERNOON AND EVENING WITH A STRONGER SHORTWAVE...MORE MOISTURE AND DYNAMICS FOR LATE SUN AFTERNOON AND EVENING ACCORDING TO THE NAM. NAM APPEARS TO BE OVERDONE WITH THIS SHORTWAVE AND TOO FAST...SO WILL GO WITH THE GFS INSTEAD WHICH IS SLOWER. UNSETTLED WEATHER WILL CONTINUE THROUGH THE PERIOD AND DID NOT MAKE TOO MANY DRASTIC CHANGES TO THE GOING FORECAST. BASICALLY...THE BEST CHANCE FOR PCPN WILL COME WITH DIURNAL HEATING...SO THIS WOULD BE IN THE AFTERNOON AND EVENING HOURS WITH LOWER CHANCES DURING THE MORNING. TEMPERATURES LOOKED GOOD AND DID NOT MAKE TOO MANY CHANGES TO THE GOING FORECAST. IN THE EXTENDED...GFS AND ECMWF SHOW A BROAD 500 MB TROUGH ACROSS THE UPPER GREAT LAKES 00Z MON WHICH SHIFTS EASTWARD 00Z TUE AND 00Z WED WITH SFC HIGH PRESSURE BUILDING IN. UPPER RIDGING THEN MOVES IN FOR 00Z THU. WILL GO WITH SLIGHT CHANCE POPS FOR SUN NIGHT AND ALSO FOR MON WITH UPPER TROUGHING IN THE AREA AND WITH ANY HEATING OR SHORTWAVE IN THE AREA...CANNOT COMPLETELY RULE RAIN OUT. BEYOND THAT...DRY WEATHER SETS INTO THE AREA THEN. TEMPERATURES WILL ALSO SLOWLY WARM TO NEAR NORMAL TOWARDS MID WEEK. && .AVIATION (FOR THE 00Z TAF ISSUANCE)... KSAW...THUNDERSTORMS AND HEAVY RAIN OVER CENTRAL UPR MI CONTRIBUTING TO MVFR TO OCCASIONAL IFR CONDITIONS AT KSAW EARLY THIS EVENING. LOOK FOR STORMS/RAIN TO GENERALLY END BY 03Z BASED ON RADAR IMAGERY AND 18Z MODEL FCSTS AS BEST LIFT SHIFTS SOUTH AND EAST OF THE FCST AREA. MOIST LOW LEVELS AND CONTINUED SRLY WIND FLOW WILL CONTRIBUTE TO IFR CONDITIONS IN FOG INTO THE EARLY OVERNIGHT HOURS. COLD FRONT MOVING THROUGH LATE TONIGHT (AROUND 08Z) AND A WIND SHIFT TO SSW BEHIND THE FRONT SHOULD BRING IN SLIGHTLY DRIER AIR AND IMPROVE VSBYS TO MVFR OR VFR. LOOK FOR LOW CIGS TO SCOUR OUT JUST AFT 12Z WITH VFR CU DEVELOPING BY MIDDAY. KCMX...ERLY FLOW CONTRIBUTING TO IFR CIGS AND OCCASIONALLY MVFR/IFR VSBSY THERE THIS EVENING. AS FLOW BEGINS TO SHIFT AROUND MORE SRLY WITH THE FRONTAL PASSAGE...LOOK FOR VSBYS TO IMPROVE TO MVFR/VFR LATE TONIGHT INTO EARLY FRI MORNING. EXPECT LOW CIGS TO SCOUR OUT JUST AFT 12Z WITH VFR CU DEVELOPING BY MIDDAY. && .MARINE (FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)... SOUTHEAST WINDS AROUND 30 KTS WITH A FEW HIGHER GUSTS TO 35 KTS HAVE BEEN COMMON TODAY. WIND SPEEDS WILL DECREASE WILL DECREASE THIS EVENING AS THE COLD FRONT CROSSES OVERNIGHT. IN FACT...WINDS SHOULD REMAIN AT OR BELOW 25 KTS THROUGH THE REMAINDER OF THE FORECAST AS A SERIES OF LOW PRESSURE SYSTEMS SWING ACROSS LAKE SUPERIOR...AND HIGH PRESSURE FINALLY BEGINS TO ROLL IN MONDAY AFTERNOON INTO TUESDAY. IN BETWEEN THESE TWO SYSTEMS...NORTHWEST TO NORTHERLY WINDS UP TO OR AROUND 20 KTS WILL BE POSSIBLE...MAINLY ACROSS THE EASTERN HALF OF LAKE SUPERIOR MONDAY INTO EARLY TUESDAY. FROM WEDNESDAY THROUGH NEXT THURSDAY...HIGH PRESSURE IS EXPECTED TO RESIDE OVER THE LOWER OHIO VALLEY...STILL INFLUENCING LAKE SUPERIOR WITH LIGHT WINDS STILL BELOW 25 KTS. && .MQT WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...KF LONG TERM...GM AVIATION...VOSS MARINE...KF
