Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
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 Aug 26, 2:40 AM EST, 4 hours 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 340 AM EDT TUE AUG 26 2003 .SHORT TERM...SURFACE ANALYSIS REVEALING A FAIRLY JUICY ATMOSPHERE IN PLACE ACROSS NORTHERN MICHIGAN BACK THROUGH WI AND MN WITH DEWPOINTS IN THE MID TO UPPER 60S. CONVOLUTED PRESSURE PATTERN IN PLACE OVER THE STATE DUE TO A NUMBER OF CONVECTIVELY INDUCED MESOSCALE FEATURES ALONG WITH MULTIPLE SMALL SCALE BOUNDARIES LYING AROUND. MAIN PUSH OF COOLER AIR AND DRIER AIR STILL LYING ACROSS SOUTHERN ONTARIO BACK INTO NORTHERN MN AND THE DAKOTAS. SECOND LINGERING BOUNDARY LYING FROM IOWA INTO NORTHERN OHIO. POCKETS OF STRONG LOW AND MID LEVEL MOISTURE CONVERGENCE ALONG AND NORTH OF THIS BOUNDARY CONTINUE TO TRIGGER CONVECTION...INCLUDING A COMPLEX OF THUNDERSTORMS NOW PRESSING INTO CENTRAL AND NORTHERN LOWER MI ATTM. 00Z UPPER AIR CHARTS AND MODEL ANALYSIS SHOWING LOW AND MID LEVEL MOISTURE PLUME (THETA-E AXIS) EXTENDING FROM THE CENTRAL PLAINS INTO THE UPPER MIDWEST. WATER VAPOR IMAGERY REVEALING SHORTWAVE ENERGY NOW PRESSING ACROSS UPPER MICHIGAN INTERACTING WITH LOW AND MID LEVEL MOISTURE...SUSTAINING CONVECTION OVER EASTERN LAKE SUPERIOR AND E UPPER MI ATTM. MEANWHILE...NEXT SHORTWAVE MOVING THROUGH WESTERN LAKE SUPERIOR ALONG SFC TROUGH HELPING TO FORCE YET ANOTHER COMPLEX OF STORMS OVER THE WESTERN U.P. FORECAST ISSUES OF COURSE CONTINUE TO BE WITH THUNDERSTORMS ACROSS THE CWA TODAY AND ASSOCIATED SEVERE WX CONCERNS. TODAY...A COUPLE OF ROUNDS OF THUNDERSTORMS ANTICIPATED OVER THE CWA THIS MORNING. POCKET OF STRONG LOW LEVEL MOIST CONVERGENCE GENERATING FIRST COMPLEX OF STORMS WILL SLIDE THROUGH A GOOD PORTION OF CENTRAL AND NORTHERN LOWER MICHIGAN VERY EARLY THIS MORNING. THEN...NEXT ROUND OF UPSTREAM CONVECTION WILL NOT BE FAR BEHIND AS UPSTREAM SHORTWAVE OVER NORTHERN MN AND AND SFC TROUGH SLIPS THROUGH. ALL MODELS HAVING A TERRIBLE TIME WITH THE UPSTREAM FEATURE WITH THE +6 HOUR ETA SOLUTIONS NOT EVEN PICKING UP ON ONGOING CONVECTION OVER WESTERN UPPER MI. BEST INSTABILITY SUGGESTS STRONGEST STORMS WILL EVENTUALLY TRACK SE THROUGH WI. BUT WITH STRONG WESTERLIES IN PLACE OVER THE NORTHERN GREAT LAKES ALONG WITH SHORTWAVE MOVING THROUGH TO THE NORTH...COMPLEX OF STORMS SHOULD CONTINUE TO TRACK E/SE IMPACTING A GOOD PORTION OF CWA THROUGH THE MORNING HOURS. OVERALL...PLAN ON HAVING LIKELY TO CATEGORICAL POPS OVER THE ENTIRE CWA TO HANDLE THE EARLY CONVECTION. THEN...WILL SEE A BREAK IN THE ACTION BY LATE MORNING AND EARLY AFTERNOON WITH SOME SUNSHINE EXPECTED. AFTERNOON HEATING AND JUICY SFC DEWPOINTS WILL COMBINE TO PRODUCE CAPES IN THE 1500-3000 J/KG RANGE (GREATEST IN THE EAST AND SOUTH). SFC TROUGH ALONG WITH REMAINING CONVECTIVE BOUNDARIES AND MESOSCALE MARINE BOUNDARIES SHOULD BE ENOUGH TO TRIGGER ADDITIONAL STORMS THIS AFTERNOON...ESPECIALLY ALONG THE LAKE HURON SIDE WITH ADDED LAKE BOUNDARY CONVERGENCE. SO...WILL CONTINUE WITH SHOWER/THUNDERSTORM CHANCES DURING THE AFTERNOON WITH THE HIGHER POPS IN THE E/SE. SEVERE WEATHER THREAT...THUNDERSTORMS PRIMARILY ELEVATED IN NATURE THUS FAR AND WILL LIKELY REMAIN THAT WAY THIS MORNING WITH NOT A GREAT DEAL OF SURFACE BASED INSTABILITY TO WORK WITH. THUS...ORGANIZED SEVERE THUNDERSTORM WINDS SHOULD BE SOMEWHAT LIMITED. HOWEVER...WITH SFC-6KM BULK SHEAR VALUES OF 35-50 KNOTS (GREATEST NORTH) STORMS HAVE THE POTENTIAL TO BECOME ORGANIZED AND PRODUCE SEVERE HAIL. WILL HAVE BETTER SEVERE WIND POTENTIAL THIS AFTERNOON AS SFC INSTABILITY RAMPS UP. .LONG TERM...MAIN FRONT AND PUSH OF DRIER AIR COMES IN LATER TONIGHT ALONG WITH A BRIEF PERIOD OF LOW LEVEL CONVERGENCE. WITH THE LOW LEVEL MOISTURE AXIS STILL IN PLACE OVER A GOOD PORTION OF THE CWA...WILL CARRY A CHANCE OF SHOWERS/THUNDERSTORMS ACROSS A GOOD PORTION OF NORTHERN LOWER MI THIS EVENING AND OVER THE FAR SE COUNTIES OVERNIGHT. WEDNESDAY AND WEDNESDAY NIGHT...DRY WEATHER STILL LOOKS GOOD FOR THE MID PART OF THE WEEK AND WILL NOT MAKE MANY CHANGES HERE. WITH PARTLY CLOUDY SKIES/LIGHT WINDS AND LOW DEWPOINTS...HAVE LOWERED TEMPS WEDNESDAY NIGHT INTO THE LOWER TO MID 40S. NO OTHER CHANGES MADE TO THE REST OF THE FORECAST.
