AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 419 PM EDT WED JUL 21 2010 .SHORT TERM /TONIGHT AND THURSDAY/... SHOWERS...AND A COUPLE OF ISOLATED THUNDERSTORMS...DEVELOPED ACROSS THE EASTERN CWA EARLY THIS AFTERNOON...BRINGING A QUICK 0.25 TO 0.75 INCHES OF WATER TO SOUTHERN SCHOOLCRAFT AND EASTERN LUCE COUNTIES. THE SHOWERS HAVE MOSTLY EXITED INTO LAKE MICHIGAN BY 1930Z. THE MAIN STORY THROUGH THIS SHORT TERM PERIOD WILL BE THE INCOMING SHOWER AND THUNDERSTORM ACTIVITY THURSDAY AFTERNOON. EXPECT THE LOW AMPLITUDE 500MB RIDGE TO BREAKDOWN ACROSS WESTERN UPPER MI THURSDAY AFTERNOON...WITH ONE SMALL WAVE NOTED IN THE OTHERWISE ZONAL FLOW. AT THE SURFACE...LOW PRESSURE ORGANIZING OFF THE CO/WY ROCKIES SHOULD SLIDE OVER SOUTHERN MN BY 00Z FRIDAY. OUT AHEAD OF THIS LOW EXPECT PLENTY OF CLOUDS TO INVADE UPPER MI DURING THE DAY...ALONG WITH SOUTHERLY WINDS RISING DEW POINTS BACK INTO THE MID 50S AND LOW 60S. FORECAST MODELS HAVE BEEN COMING INTO BETTER AGREEMENT WITH THE ONSET OF PRECIPITATION...WITH THE BEST CHANCE BEING OVER SW MENOMINEE COUNTY AND ACROSS FAR WESTERN LS. HAVE PAINTED POPS TO REFLECT THIS THINKING. LIGHTER WINDS ALOFT SHOULD KEEP THE SOUTHERLY WINDS AROUND 10KTS THURSDAY AFTERNOON...WITH FEWER GUSTS THAN TODAY. .LONG TERM /THURSDAY NIGHT THROUGH NEXT WEDNESDAY/... THURSDAY NIGHT THROUGH SATURDAY...THIS PERIOD GENERALLY FEATURES RAIN CHANCES THROUGHOUT...FIRST WITH THE WARM FRONTAL INFLUENCE THURSDAY NIGHT AND THEN LOWER CHANCES THEREAFTER AS AN UPPER LEVEL LOW SWINGS A FEW S/W TROUGHS THROUGH THE CWA. OPTED TO GO DRY FRIDAY AFTN/EVENING AS DEEPER MOISTURE IS STRIPPED OUT UNDER RISING 500MB HEIGHTS RISE/SUBSIDENCE ALOFT. THURSDAY NIGHT...DESPITE WHAT THE MAJORITY OF OPERATIONAL GUIDANCE SHOWS...PRECIPITATION CHANCES FOR THURSDAY NIGHT ARE NOT STRAIGHTFORWARD AND A SPLIT IN THE PRECIPITATION AS IT NEARS UPPER MICHIGAN APPEARS VERY POSSIBLE. THE QUESTIONS SURROUNDING THIS PERIOD HINGE ON THE EVENTUALLY LOCATION OF THE SURFACE WARM FRONT AS HEAVIEST PRECIPITATION/BEST INSTABILITY AND QG FORCING WILL BE TIED TO THIS FEATURE. BOTH THE 00Z/EC AND THE 12Z/NAM INDICATE BETTER 500MB ENERGY AND CORRESPONDING QG LIFT SKIRTS ACROSS THE WI BORDER AND THEN ACROSS NORTHERN MICHIGAN WHILE THE MAIN S/W SHIFTS OUT OF NORTH DAKOTA AND REMAINS NORTH OF LAKE SUPERIOR. WILL GO WITH THE THINKING THE WARM FRONT WILL REMAIN SOUTH OF UPPER MICHIGAN. THE FORECAST REFLECTS THIS IDEA AND MAINTAINED LIKELY POPS ALONG THE WI BORDER AND HIGH CHANCE POPS OVER THE KEWEENAW AND WESTERN LAKE SUPERIOR. FRIDAY THROUGH SATURDAY AFTERNOON...WITH THE ULJ DIRECTLY OVER UPPER MICHIGAN THINK THE BEST PRECIPITATION CHANCES WILL REMAIN NORTH OF LAKE SUPERIOR CLOSER TO THE TRACK OF THE 700MB TROUGH/MOISTURE. KEPT PRECIPITATION CHANCES GOING FRIDAY MORNING THOUGH AS 500MB HEIGHTS FALLS REMAIN OVER THE CWA. DECIDED TO GO DRY BY THE AFTERNOON AND EVENING WHEN DEEPER MOISTURE IS REMOVED PER NAM/EC RH PROGS. NEXT S/W SWINGS THROUGH THE UPPER GREAT LAKES ON SATURDAY...AGAIN THOUGH NOT IMPRESSES WITH AVAILABLE MOISTURE FOR PRECIPITATION PRODUCTION. QG FORCING ASSOCIATED WITH THIS S/W ENTERS THE WEST LATE FRIDAY NIGHT...SO BROUGHT LOW RAIN CHANCES BACK FOR THEN. SATURDAY NIGHT THROUGH NEXT WEDNESDAY...BEHIND THE SATURDAY S/W...STRONG SUBSIDENCE SHOULD ALLOW FOR CLEARING SKIES BY LATE SATURDAY NIGHT AND INTO SUNDAY MORNING. BUILDING MID LEVEL RIDGING OVER THE DAKOTAS LEADS TO RISING HEIGHTS AND DRY WEATHER OVER THE UPPER GREAT LAKES THROUGH MONDAY NIGHT. AS WITH THE PAST FEW DAYS THERE ARE STILL INDICATIONS OF A WEAK TROUGH MOVING THROUGH ON TUESDAY/TUESDAY NIGHT. UNCERTAINTY REMAINS AS TO WHERE THE SFC WARM FRONT WILL SETUP...BUT FELT CHC POPS REMAIN JUSTIFIED TO ACCOUNT FOR THIS UNCERTAINTY. && .AVIATION /FOR THE 18Z TAF ISSUANCE/... VFR CIGS AND VIS SHOULD CONTINUE THROUGH 18Z THURSDAY. SCT TO BKN FAIR WEATHER CUMULUS AND WESTERLY WINDS GUSTING NEAR 20KTS THIS AFTERNOON WILL DIMINISH LATE THIS AFTERNOON...AS HIGH PRESSURE PUSHES IN FROM THE WEST.

The national radar mosaic for the moment the first event began.
1 rip current. Local standard time, as filed.
A 62-year-old Wisconsin man drowned near Picnic Rocks on the afternoon of the 21st. A wave pushed him away from the sandbar at Picnic Rocks, and he was pulled under the water by the strong longshore current which had developed from gusty north winds of 10 to 20 mph.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
