The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jul 31, 2:46 PM EST, 3 hours 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 346 PM EDT WED JUL 31 2002 SEVERAL AREAS OF CONCERN FOR TONIGHT AND THURSDAY. FIRST IS REMNANT CONVECTION AND ASSOCIATED SHORT WAVE TROUGH MOVING ACROSS CENTRAL/ EASTERN WI LATE THIS AFTERNOON. MODIFIED APX SOUNDING FOR 85/66 YIELDS CAPES AROUND 3000 J/KG WITH NO CAP...AS SHORT WAVE TROUGH MOVES ACROSS THE STATE THIS EVENING AND INTERACTS WITH INSTABILITY ALREADY IN PLACE...EXPECT TO SEE AN INCREASE IN SHOWER/THUNDERSTORM COVERAGE ESPECIALLY ACROSS NORTHERN LOWER. SECOND AREA OF CONCERN IS ALONG BOUNDARY ACROSS EASTERN SD/SOUTHERN MN...DIVIDING COOL OUTFLOW AIR FROM THIS MORNING FROM WARM/MOIST AIR ACROSS NE/IA. LOW LEVEL JET IMPINGING UPON THIS BOUNDARY SHOULD SET OFF ANOTHER ROUND OF CONVECTION ACROSS SOUTHERN/CENTRAL MN NORTH OF MID LEVEL THERMAL RIDGE. THIS CONVECTION SHOULD WORK ITS WAY EAST ACROSS NORTHERN WI AND TOWARD THE FORECAST AREA OVERNIGHT...AND MAY STILL BE ONGOING TOMORROW MORNING OVER PARTS OF THE AREA ESPECIALLY ACROSS EASTERN UPPER/NORTHWEST LOWER...WHICH WILL COMPLICATE AFTERNOON CONVECTION EVOLUTION A BIT ESPECIALLY IF FRONT PUSHES INTO AREA PRIOR TO FRONTAL ARRIVAL. FOR TONIGHT PLAN ON GOING WITH LIKELY POPS ACROSS EASTERN UPPER/NORTHWEST LOWER...AND CHANCE POPS OVER NORTHEAST LOWER. ON THURSDAY...WITH POTENTIAL FOR SOME MORNING CONVECTION WILL GO WITH LIKELY POPS ROUGHLY NORTH OF AN MBL-APN LINE WITH NO TIMING...AND CHANCE MORNING/LIKELY AFTERNOON THUNDERSTORMS FOR THE REST OF THE AREA. BEST SEVERE THREAT MAY END UP ACROSS NORTHERN LOWER DURING THE AFTERNOON WHERE GREATEST DESTABILIZATION IS EXPECTED. WILL CONTINUE WITH LIKELY POPS THURSDAY EVENING ACROSS NORTHERN LOWER AS THE FRONT SWEEPS ACROSS...FOLLOWED BY A DRY FRIDAY WITH DIURNAL CU/SC DEVELOPMENT. TEMPERATURES...LOWS TONIGHT WILL BE HELD UP BY CLOUDS/HIGH DEW POINTS/ SOUTHERLY WINDS...GENERALLY UPPER 60S/LOWER 70S. FOR NOW WILL HOLD TEMPERATURES DOWN A BIT OVER EASTERN UPPER/FAR NORTHWEST LOWER DUE TO UNCERTAINTY ABOUT CLOUD COVER THURSDAY AFTERNOON...BUT FARTHER SOUTHEAST WILL PUSH HIGHS INTO THE 90S. EXPECT HIGHS TO COOL BACK INTO THE 70S/NEAR 80 BEHIND FRONT FRIDAY. WINDS...TONIGHT WILL SEE AN INCREASING SOUTH/SOUTHWEST GRADIENT AHEAD OF APPROACHING COLD FRONT. ALTHOUGH GRADIENT NOT PARTICULARLY STRONG...925/850MB WINDS IN THE 20-30 KT RANGE SHOULD PROVIDE FOR A GUSTY AFTERNOON THURSDAY WITH MIXING. FRONT NOT EXPECTED TO REACH WESTERN PORTIONS OF THE FORECAST AREA UNTIL EARLY THURSDAY EVENING... THEN SWEEPING EAST THROUGH LOWER MICHIGAN THURSDAY NIGHT...SO WINDS WILL SHIFT TO NORTHWEST. DECENT CAA BEHIND FRONT WILL PROBABLY RESULT IN STRONGER WINDS ALONG THE LAKE SUPERIOR/LAKE MICHIGAN/NORTHERN LAKE HURON SHORELINE AREAS THURSDAY NIGHT. SATURDAY THROUGH WEDNESDAY (EXTENDED)...SURFACE HIGH EXTENDING FROM MICHIGAN NORTHEAST INTO WESTERN QUEBEC WILL DOMINATE SATURDAYS WEATHER...WITH SUNNY SKIES AND SEASONABLE EARLY AUGUST TEMPERATURES. AS FOR THE EXTENDED MRF SHOWING A COMPLETE PHASE REVERSAL THIS RUN FROM ITS PREVIOUS RUN...NOW BUILDING A RIDGE UP INTO THE NORTHERN PLAINS AS A TROUGH DIGS INTO THE WESTERN U.S...GETTING AWAY FROM ITS GREAT LAKES TROUGH IDEA ON MONDAY WHICH WAS DISCOUNTED YESTERDAY. THIS IS A HUGE CHANGE...WITH THE MRF (SUPPORTED BY 30/12Z ECMWF RUN) NOW PUSHING 594 HEIGHTS INTO THE AREA BY MIDWEEK AND SIGNALING POTENTIAL FOR ANOTHER PUSH OF HEAT INTO THE STATE. ENSEMBLE MEANS ARE FLATTER WITH THE FLOW ACROSS THE GREAT LAKES REGION (SIMILAR TO YESTERDAYS OPERATIONS RUNS) WITH LESS DIGGING OF THE WESTERN TROUGH...ALTHOUGH THE OPERATIONAL IDEAS ARE PROBABLY NOT TOO BAD WITH THE DTX ETAXX ALSO PUMPING THE RIDGE INTO THE NORTHERN PLAINS. AT THE VERY LEAST WILL START TO TREND FORECAST HIGH TEMPERATURES UPWARD NEXT WEEK...WITH WARMER THAN NORMAL TEMPERATURES BEYOND MONDAY. AS FOR RAIN CHANCES...POSITION OF BAROCLINIC ZONE ALONG SOUTHERN EDGE OF WESTERLIES WILL BE A TOUGH CALL. HOWEVER RAIN CHANCES SUNDAY LOOKING LESS LIKELY...SO WILL PULL RAIN CHANCES OUT ALTOGETHER...AND JUST KEEP RAIN CHANCES IN FOR NORTHERN LOWER MONDAY. EVENTUALLY...SUSPECT IF HEIGHTS BEGIN TO RISE ACROSS THE WESTERN LAKES ASSOCIATED FRONTAL BOUNDARY WILL EVENTUALLY HAVE TO PUSH NORTH. IN ADDITION...WILL BE GETTING CLOSER TO POTENTIAL MCS GENESIS REGION TO THE NORTHWEST. SO PLAN ON CARRYING RAIN CHANCES BOTH TUESDAY AND WEDNESDAY. COORDINATED WITH MQT/GRR/DTX. .APX...NONE. JPB
