Property damage: $817,000

What happened

The episode as NWS MQT wrote it up.

An approaching cold front interacting with an extremely unstable airmass triggered a widespread outbreak of severe weather across west and central Upper Michigan from late afternoon on the 28th to just after sunrise on the 29th. Of the 13 counties in west and central Upper Michigan, only Alger and Keweenaw counties escaped without severe weather, as there were at least 40 individual reports of damaging wind or large hail during the event. The storms also produced torrential downpours and minor flooding over Gogebic County during the early morning hours of the 29th.

What forecasters said that day

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 Marquette, MI wrote its last area forecast discussion before the first event at Jul 28, 2:00 PM CST, 35 minutes earlier.

400 PM EDT FRI JUL 28 2006

.DISCUSSION...
.SHORT TERM...
MAIN FCST CONCERNS TONIGHT ARE SHRA/TSRA COVERAGE AND SVR POTENTIAL.

WV IMAGERY AND RUC ANALYSIS INDICATED WNW MID/UPPER LEVEL FLOW
THROUGH THE WRN GRT LAKES BTWN THE DOMINANT SUBTROPICAL RDG OVER THE
SW AND A TROF OVER HUDSON BAY. MOST SIGNIFICANT UPSTREAM SHRTWV WAS
LOCATED WELL TO THE W FROM SRN SASK INTO NRN MT. AT THE SFC(18Z)...A
SLOW MOVING COLD FRONT EXTENDED FROM NRN ONTARIO INTO NE MN. TEMPS
HAVE CLIMBED INTO THE LOWER 90S OVER MUCH OF THE W HLF OF UPR MI
WITH DEWPOINTS IN THE MID 60S LEADING TO MLCAPES AOA 2K J/KG. LAKE
SUPERIOR BREEZE BNDRY HAS ALREADY TRIGGERED TSTMS OVER N CNTRL UPR
MI WHILE ISOLD TSRA HAVE ALSO DEVELOPED BTWN KMQT AND KIMT.

IN ADDITION TO THE ONGOING TSMS OVER W AND CNTRL UPR MI
EXPECT THE COLD FRONT TO ALSO PROVIDE FOCUS FOR ADDITIONAL TSTM
DEVELOPMENT LATER THIS EVENING WITH STORMS MOVING INTO UPPER
MICHIGAN AND POSSIBLY DEVELOPING INTO AN MCS WITH GREATER COVERAGE.
FAVORABLE 0-3KM AND 0-6KM SHEAR VALUES IN THE 35-40 KT RANGE WILL BE
SUFFICIENT FOR ORGANIZED CONVECTION AND POTENTIAL FOR DAMAGING
WINDS. THE RELATIVELY HIGH FREEZING LEVEL NEAR 15K FT WILL BE
UNFAVORABLE FOR LARGE HAIL ALTHOUGH ANY SUPERCELLS THAT DEVELOP
WOULD BE CAPABLE OF PRODUCING LARGE HAIL AND EVEN ISOLD TORNADOES.

.LONG TERM...

SATURDAY THROUGH MON MORNING...WITH WARM FRONT LINGERING ACROSS THE
AREA AND AXIS OF FRONT STILL IN QUESTION COULDNT JUSTIFY CHANGING
GOING WX. ALTHOUGH GIVEN SLIGHTLY COOLER 850 HPA TEMPS I DID DROP
HIGHS A FEW DEGREES ON SAT AND SUN. CLOUD COVER WILL BE THE DECIDING
FACTOR THOUGH AS MORE CLOUDS THAN EXPECTED COULD EASILY BUST THE
FORECAST. MONDAY STILL LOOKS TO BE THE WARMEST DAY WITH HIGHS
REACHING INTO THE UPPER 90S. AGAIN CLOUD COVER ASSOCIATED WITH ANY
MCS DEVELOPMENT WILL PROVE TO DICTATE HIGHS...THOUGH GIVEN DPTS IN
MID TO UPPER 60S...90 DEGRESS VS. 95 DEGREES WILL STILL FEEL
MISERABLE AS HEAT INDEX VALUES WILL BE EASILY INTO THE 90S AND
POSSIBLY CLOSE TO 100. WILL LET FUTURE SHIFTS DECIDE WHETHER OR NOT
TO ISSUE ANY PRODUCTS TO HIGHLIGHT HEAT.

MON AFTERNOON THROUGH WEDNESDAY...LEFT WEATHER FORECAST THE SAME FOR
MON AND TUE. COOL FRONT STILL ON TRACK TO PASS THROUGH CWA SOMETIME
TUE AFTN. ON WED 850-500 HPA DIV Q FIELDS/500 MB HEIGHT FIELDS
INDICATE STRONG AREA OF LIFT ACROSS UPPER MICHIGAN ASSOCIATED WITH
STRONG LOW PRES TROUGH PASSING THROUGH THE CWA. PUT IN 30 POPS
TRAVERSING THROUGH THE AREA ON WEDNESDAY.

THURSDAY AND FRIDAY...FORECAST LOOKS DRY WITH HIGH PRESSURE RIDGE
BUILDING IN FROM THE WEST. BROUGHT DPTS DOWN A BIT AS IT LOOKS LIKE
DECENT MIXING...TO 70 TO 80 HPA...COULD TAKE PLACE PER GFS
SOUNDINGS. DIDNT GO AS DRY AS SOUNDINGS INDICATED BUT KEPT DPTS IN
THE MID 50S. CAN DEFINATELY SEE THESE GO LOWER EVEN INTO THE UPPER
40S...BUT WITH NW FLOW...NOT EXPECTING ADDTIONAL DRYING DUE TO
TOPOGRAPHY. WITH DPTS AS THEY ARE CAN GET RH VALUES IN THE UPPER 20S
AND LOW 30S...HOWEVER WITH RIDGE BUILDING IN WINDS SHOULD BE
INSIGNIFICANT.

Within this area, just behind the VFW building off of VFW Road, there was a localized area where nearly twenty trees were blown down. The wind damage continued across Highway M-28 and eastward along the entire length of old M-28.
