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 Grand Rapids, MI wrote its last area forecast discussion before the first event at Jul 6, 12:49 PM EST, 4 hours 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 149 PM EDT SUN JUL 6 2003 LATEST VIS LOOP SHOWS WELL DEFINED SHORT WAVE JUST ENTERING SOUTHWEST WISCONSIN. SEVERAL SPOKES OF CONVECTION ARE DEVELOPING ON THE SOUTHERN SIDE OF THE WAVE. DIFFERENTIAL HEATING BETWEEN THE SPOKES IS HELPING TO MAINTAIN INSTABILITY AS THEY PCPN MOVES EAST. THIS WAVE AND ITS ASSOCIATED PCPN CHANCES WILL BE THE FOCUS OF THE FCST. THE SHORT RANGE MODELS WERE IN DECENT AGREEMENT THRU WED AM WITH THE EVOLUTION OF THE AFOREMENTIONED SHORT WAVE AS WELL AS WITH A COLD FRONT THAT IS MOVING THRU THE DAKOTAS CURRENTLY WHICH WILL MOVE THRU THE CWA ON MONDAY. FOR TONIGHT...INSTABILITY IS HIGH ACROSS THE CWA AS EVIDENT BY EHI GREATER THAN 1 ALONG WITH CAPES AROUND 2K J/KG. SFC BASES LIS ARE IN THE -5 TO -8 RANGE ACROSS THE SW CWA BUT ABOVE 0 IN THE NORTHEAST. LAPS SOUNDINGS HAVE SHOWN A SLOW INCREASE IN LOW LVL MOISTURE DURING THE PAST 6 HRS...BUT SOME DRY AIR IS STILL EVIDENT ABV 850 MB. NOT LOOKING FOR THE ENVIRONMENT TO CHANGE TOO MUCH LATER THIS AFTERNOON AND EVENING WITH THE HIGHEST INSTABILITY AND MOISTURE REMAINING IN THE SRN CWA. SINCE FREEZING LVLS ARE OVER 13K FT...GREATEST THREAT WOULD BE WIND. THERE IS SOME VEERING IN THE LOW LVLS BUT VECTORS ARE SMALL. HOWEVER, THEY ARE A LITTLE GREATER WEST OF THE LAKE. THUS THE THREAT OF ROTATION WILL INCREASE A BIT AS EVENING APPROACHES. WILL GO WITH LIKELY POPS ACROSS THE SOUTH AND CHC POPS ELESWHERE. FOR MONDAY AND MONDAY NIGHT...THE OBVIOUS CONCERN IS THE COLD FRONT THAT WILL MOVE THRU THE AREA. BY MID AFTERNOON THE FRONT WILL STRETCH FROM THE WRN UP THRU CENTRAL WI INTO ERN IA AND THEN TAKE ON A MORE EAST-WEST CONFIGURATION MONDAY EVENING AS IT BECOMES MORE PARALLEL TO THE FLOW. INSTABILITY IS MAXIMIZED ACROSS THE SRN CWA WITH LIS CLOSE TO -10C...TOTAL TOTALS IN THE MID 50S...AND SHOWALTER INDEX -6 TO -8. MOISTURE CONVERGENCE REMAINS MAXIMIZED JUST AHEAD OF THE FRONT AND DOESNT MOVE INTO THE CWA UNTIL AFTER 00Z...AFTER MAX HEATING. GIVEN THAT TONIGHT/S STORMS WILL PROBABLY BE ONGOING DURG THE MORNING WILL CARRY LIKELY POPS IN THE SOUTH FOR BOTH PERIODS. WILL CONTINUE WITH CHC POPS IN THE NORTH BOTH PERIODS. FOR TUESDAY THRU WED...THE FRONTAL BOUNDARY SINKS SOUTH WITH TIME...PUSHED BY SWD SINKING FRONTAL BOUNDARY. WILL GO WITH DRY WX THRU THE PERIOD. CU WILL BE ENHANCED ON WEDNESDAY AS WEAK TROUGHING ALOFT ADVECTS COOLER AIR SOUTHEAST ACROSS THE CWA. WILL MAINTAIN MO CLR NIGHTS AND PT SUNNY DAYS. COOLER AIR IS CERTAINLY ON THE WAY AS H85 TEMPS FALL FROM 20C ON TUESDAY TO 9C ON WED AFTERNOON. 93 EXTENDED FORECAST ZONAL UPPER FLOW PATTERN WILL FINALLY SHOW SOME CHANGES IN THE EXTENDED PERIOD AS A STRONG SHORT WAVE TROUGH DIGS INTO THE EASTERN U.S. AND ALLOWS AMPLIFICATION OF THE LONG WAVE PATTERN. THIS WILL ALLOW DRIER AND COOLER AIR TO FINALLY MAKE A STRONGER PUSH INTO THE GREAT LAKES REGION THAN HAS BEEN THE CASE RECENTLY. ON WEDNESDAY...A CANADIAN SFC HIGH WILL BE NOSING INTO LOWER MICHIGAN WITH PRECIP SUPPRESSED SOUTH INTO INDIANA. THE 12Z ETA AND GFS SHOW CONVECTION STRETCHING FROM INDIANA TO THE DAKOTAS ALONG AN AREA OF MOISTURE POOLING ON THE WESTERN EDGE OF THE SFC HIGH LATE WEDNESDAY. AS THE HIGH MOVES EAST ON THU...A SFC LOW WILL PUSH INTO THE OHIO VALLEY AND THE NORTHERN EDGE OF THE PRECIP SHIELD WILL MOVE ACROSS LOWER MICHIGAN. WILL ADD CHANCE POPS FOR THU. ONCE THIS SYSTEM GETS EAST OF LOWER MICHIGAN...THE UPPER FLOW WILL GO NW AND IT APPEARS A DRY PERIOD IS IN STORE THROUGH THE WEEKEND WITH NEAR OR SLIGHTLY BELOW NORMAL TEMPS. OSTUNO .GRR...NONE.
