Location: Mc Leods Corner, Michigan

This EF0 tornado ran 0.3 miles across Luce County on July 8, 2016, touching down at 5:56 PM EDT and reaching 75 yards wide. It killed nobody, and did $5,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

EF065 to 85 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded

A low pressure trough moving through a moist and unstable air mass produced isolated severe thunderstorms over portions of central Upper Michigan, including a weak tornado near Newberry.

A weak tornado was captured on video and tree damage was later confirmed by a Michigan DNR pilot. Overhead photos from the DNR revealed that the tornado knocked down numerous trees and basically circulated in the same spot for several minutes before dissipating.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

Area Forecast Discussion
National Weather Service Marquette MI
438 PM EDT FRI JUL 8 2016

.SHORT TERM...(This evening through Saturday)
Issued at 254 PM EDT FRI JUL 8 2016

Upper low at 500 mb will continue moving across the U.P. this
afternoon and move out of the U.P. this evening. As this low
continues to move through, showers and thunderstorms will continue
to slowly diminish in coverage this evening and drier weather will
move in for Sat which is already covered in the forecast. Low levels
will remain moist through tonight and this will cause some areas of
fog which is already in the forecast. Will be dry on Sat. Did hang
on to some showers in north wind upslope areas of Marquette County
tonight. Overall, did not make too many changes to the going
forecast.

.LONG TERM...(Saturday night through Friday)
Issued at 437 PM EDT FRI JUL 8 2016

Medium range guidance remains fairly stable on the overall pattern
over N America thru next week. Underneath a strong positive height
anomaly still dominating northern Canada, a band of lower heights
extends from off the Pacific NW coast across the northern Plains to
south of Greenland. This is leading to a low amplitude/general zonal
flow across the northern CONUS. A vigorous shortwave now over the
Upper Great Lakes will continue tracking e, reaching New England
Sun. Meanwhile, a deep mid level low off the Pacific NW coast will
settle into the Pacific NW this weekend. This trof will be unusually
deep as it shifts across the northern Rockies as GEFS indicates
500mb height anomalies of 3.5 standard deviations blo the long term
July avg over WY Mon. Ahead of this feature and behind the previous
trof, a ridge will be forced to build across central N America,
resulting in a period of nw flow and less humid/more pleasant July
weather developing over the weekend. Then as the pattern progresses,
the Upper Great Lakes region will be back in a warming trend early
next week as deep sw flow develops ahead of the Rockies trof which
will be shifting ene. At least a couple very warm to hot and
uncomfortably humid days appear likely next week. Farther down the
line, arrival of the trof will bring at least another temporary cool
down and more comfortable conditions late next week. As for pcpn,
expect dry weather over the weekend and into Mon under ridging, then
developing waa/moisture advection pattern downstream of the trof
shifting e from the northern Rockies will bring shra/tsra chances
Tue/Wed. Faster trend in the pattern progression noted in recent
medium range guidance may lead to a return of dry weather Thu/Fri,
but model differences in the structure of the trof reaching the
Great Lakes and possible shortwaves moving thru it lead to low
confidence in the pcpn fcst late week.

Beginning Sat night, sfc high pres ridge will move over the area,
leading to a cool night under clear skies. Mins over the interior
should slip down into the 40s with low/mid 40s not out of the
question for traditional interior cold spots.

Sun/Sun night, as in recent days, some models indicate a potential of
-shra as shortwave energy cuts thru what is an otherwise building
ridge. In fact, more guidance indicates that potential today. The
eastern edge of the low-level jet is far enough e to possibly support
-shra reaching western Upper MI. However, with the ridge building
and with the ridge axis to the w over MN, will hold onto a dry fcst
except for western Lake Superior including Isle Royale which may be
affected before the pcpn dissipates. Away from lake breezes on Sun,
high temps will rebound well into the 70s/around 80F.

With axis of sharpening mid/upper ridge over the Upper Great Lakes
on Mon, dry weather should prevail. Temps will rise back above
normal into the low/mid 80s for the most part. Dwpts will also begin
to creep up into the uncomfortable range.

Tue thru Fri, deep trof over the central/northern Rockies Mon will
gradually weaken as it shifts ene, reaching the Upper Great Lakes
late Wed/Thu. Models show a solid faster trend with the trof. As low
level jet ahead of trof translates eastward and then as cold front
passes Wed, expect some chc of shra/tsra Tue/Wed. Capping may become
quite strong as thermal ridge arrives, so shra/tsra potential may be
limited. At this point, nothing more than chc pops are warranted. It
will be very warm/humid Tue/Wed with max temps well into the 80s for
most locations and dwpts well into the 60s, making conditions even
more uncomfortable. With the trof evolving into a mid level low over
Hudson Bay late week, there are model differences in the structure
of the flow and possible shortwaves moving across the Upper Great
Lakes, leading to low confidence in the pcpn fcst late week. Right
now, it would appear pcpn chances will be on the low side Thu/Fri.
Temps will fall back toward normal with lower dwpts making
conditions more comfortable.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1245 PM EDT FRI JUL 8 2016

Showers and thunderstorms expected during peak heating as a strong
upper low moves overhead. Best chances for additional showers/storms
will be at SAW. Confidence is low for this forecast as changeable
weather will continue. Low clouds and fog will develop tonight at
KIWD and KSAW as low levels remain moist. Expect MVFR range
conditions tonight at CMX. All sites will go to VFR Sat morning as
mixing and drying occur.
&&

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 254 PM EDT FRI JUL 8 2016

As a strong upper level low moves away, N winds will increase up to
25 kts by this evening and will last into Sat afternoon. Areas of
fog will continue into Sat morning as well before dry air mixes out
on Lake Superior. High pressure will move into the area through
Monday. Winds look to stay at or below 20 knots from Sat night
to Wed.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
