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 25, 6:24 PM EST, 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 724 PM EDT FRI JUL 25 2008 .AVIATION...LINE OF STORMS AHEAD OF COLD FRONT WILL BRING IFR CONDITIONS TO PLN SHORTLY. TO THE SOUTH AND EAST...LINE IS NOT/WILL NOT BE CONTINUOUS. OCCURRENCE OF THUNDER NOT CERTAIN AT TVC/APN...BUT PROBABLY LIKELY LATE THIS EVENING. SHRA/TSRA SHOULD BE OUT OF THE PICTURE AT THE TAF SITES BY 06Z...WITH VFR CONDITIONS AFTER AS VERY DRY AIR MOVES IN. JZ && .DISCUSSION...ISSUED 356 PM FRI JUL 25... MCV IS MOVING THROUGH THE 500 MB IN N WISCONSIN AND IS INTERACTING WITH THE SFC TROUGH IN WISCONSIN. THERE IS A SLIGHTLY STRONGER VORT DIVING INTO THE 500 MB TROUGH. TONIGHT...THE MAIN CONCERN WILL BE THE SPEED OF THE COLD FRONT AND THE INTERACTION OF THE MCV. NAM12, GFS40, AND RUC13 ALL SUGGESTING THE TIMING OF THE MCV INTO TVC AROUND 00Z WITH THE TROUGH TO BE JUST BEHIND SAGGING INTO N LOWER SHORTLY AFTER. THIS WOULD BRING SHOWERS AND THUNDERSTORMS INTO PLN BETWEEN 00Z AND 03Z AND APN AROUND 03Z TO 06Z. THE FRONT ITSELF SHOULD BE EXITING THE REGION BY 12Z SO THAT E UPPER AND NW LOWER MAY SEE SOME CLEARING BY DAY BREAK. WITH TIMING OF THE FRONT THERE WILL BE SOME DIURNAL HEATING LEFT FOR NW LOWER. SO CANT RULE OUT SMALL HAIL OR WIND GUSTS TO 40 MPH, AS THE FRONT PASSES. HOWEVER, THINK THAT MOST LIKELY THERE WILL BE LITTLE IN THE WAY OF SEVERE WEATHER WITH HIGH FREEZING LEVELS AND SOME MID LEVEL CAPPING. THERE MAY BE SOME THREAT TO TRAINING AS THE 850 MB WINDS ARE 75%-80% OF THE 850-300 MB WIND SPEED. ESPECIALLY WITH THE PWAT AROUND 1.25. LUTZ SAT THRU MON...EXCEPTIONAL STRETCH OF MID SUMMER WEATHER TO CONTINUE FOR THE MID TERM...AS LOCAL AREA REMAINS DOMINATED BY LINGERING TROUGHING ALOFT BUT EXTENDED LOW LEVEL RIDGING SPANNING FROM CENTRAL MANITOBA THRU THE MIDWEST. BIGGEST CONCERN IS WITH SMALL CHANCES FOR ANY PRECIP AS WEAK SHORTWAVES DROP THRU THE MEAN CYCLONIC GYRE PARKED OVR HUDSON BAY...THOUGH OVERALL LACK OF MOISTURE (1000-500 MB RH ONLY 30-40%) LOOKS TO PRECLUDE ANYTHING SIGNIFICANT. BIGGEST CHANGE TO GOING FCST WAS TO ADD SPRINKLE MENTION ACRS SOUTHERN HALF OF THE CWA GIVEN TIGHTENING 900-800MB THERMAL GRADIENT AS GUIDANCE CONTINUES TO HINT AT POTENTIALLY MORE PRONOUNCED WAVE DROPPING THRU THE FLOW. CERTAINLY NOTHING TERRIBLE IMPRESSIVE...BUT QUICK UPTICK IN 700-600MB RH PER TIME HEIGHTS AND QUICK SHOT OF QG SUPPORT SEEM TO SUPPORT SOME SMALL POTENTIAL...THOUGH DRY DOWNSTAIRS SHOULD KEEP ANYTHING ISOLATED. TEMPS TO REMAIN NEAR CLIMO THRU THE PERIOD. LATER PERIODS (MON NIGHT THRU FRI)...RATHER BENIGN WX TO PERSIST THRU THE EXTENDED...AS PATTERN REMAINS DOMINATED BY PERSISTENT TROUGHING FROM THE GULF OF ALASKA EASTWARD TOWARD BRITISH COLUMBIA...WITH A DOWNSTREAM RIDGE PARKED ACRS THE INTERMOUNTAIN WEST/WESTERN HIGH PLAINS...AND FURTHER TROUGHING EVIDENT OVR THE EASTERN GREAT LAKES/EAST COAST. END RESULT WITH NORTHERN MICHIGAN ON THE BACKSIDE OF SAID TROUGH...AND HIGHLY CONFLUENT FLOW PATTERN ALOFT SHOULD BE AN ELONGATED ANTICYCLONE DRIFTING THRU THE REGION BASICALLY MON ONWARD. ONLY POTENTIAL PROBLEM SEEN AT THIS TIME IS SMALL POTENTIAL FOR ONE OR MORE WEAK NORTHERN STREAM SHORTWAVES TO TOP THE WESTERN RIDGE AND MAKE A RUN AT THE AREA (I.E. AIDING IN FURTHER DEEPENING EASTERN CONUS TROUGH TO THE WEST)...HOWEVER... CONFIDENCE IN ANY PARTICULAR MODEL SCENARIO LESS THAN STELLAR...AND SIMPLY PREFER TO KEEP GOING DRY FCST INTACT...WITH MAJORITY OF MOISTURE/INSTABILITY BOTTLED UP WELL SOUTH ALONG EAST-WEST ELONGATED SFC FRONT. TEMPS LOOK TO REMAIN AT OR BELOW CLIMO (NO SURPRISE THIS SUMMER) WITH TROUGHING PERSISTING JUST TO THE EAST...AND NORTHERN MICHIGAN ON THE WESTERN FRINGE OF COOLER AIRMASS.
