What was reported inside it

Time	Report	Where	Remark
Jul 4, 5:00 PM CDT	HEAVY RAIN 1	4 S Swanson, MI	DELAYED REPORT. THE DURATION OF THE HEAVY RAIN EVENT WAS 2 HOURS.
Jul 4, 6:00 PM CDT	HEAVY RAIN 3	1 Ese Daggett, MI	MEASURED 3.0 INCHES OF RAINFALL NEAR DAGGETT IN ABOUT A TWO HOUR PERIOD. REPORT VIA SOCIAL MEDIA. VERY HEAVY RAINFALL FROM 4:30 TO 5:30 P.M. EDT.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Green Bay/Straub, WI (KGRB), launched 12:00Z, 9.4 hours before the alert went out and 111 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this flash flood warning went out, 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 this flash flood warning went out at Jul 4, 3:38 PM CDT, 45 minutes earlier.

Area forecast discussion, Jul 4, 3:38 PM CDT, 45 minutes before

Area Forecast Discussion
National Weather Service Marquette MI
438 PM EDT Wed Jul 4 2018

.SHORT TERM...(This evening through Thursday)
Issued at 428 PM EDT WED JUL 4 2018

A scorcher for this 4th of July as heat index values are near 100
early this evening as temps are around 90F and dwpnts have surged
into the lower 70s over much of Upper Michigan. Cluster of long
lived showers and t-storms which have survived since last night
over the Dakotas are now moving across western Upper Michigan.
Turned much cooler there once these showers and t-storms worked
through. These t-storms have been gusty storms so far with peak
winds 30-40 mph. Limited deep layer shear has kept hail to a
minimum thus far. Have seen frequent cloud to ground lightning
strikes along with heavy downpours. These showers and t-storms are
well out ahead of primary cold front which is pushing into
northwest MN. Given the low 90s/low 70s temps/dwpnts there is
certainly ample instabilty to support occasionally strong
updrafts. However, deep layer shear mainly less than 25 kts with
stronger forcing lifting north of Lk Superior has thus far
restricted persistently strong updrafts and t-storms.

High res short range models have struggled with t-storm evolution
throughout the day but are starting to latch onto reality a bit
better now. Btwn that guidance and radar/satellite trends, expect
initial showers and t-storms to slowly move into cntrl Upper
Michigan by 7 pm this evening. Pocket of higher instability may
allow these storms to perk up briefly. Still though the lack of deep
layer shear will probably work against sustained stronger storms.
Also have to watch initial cluster of t-storms that are lifting into
south cntrl Upper Michigan, though shear is even weaker here so
these storms are only slowly drifting north. And later this evening
the showers and t-storms currently over wcntrl WI could lift back
into western Upper Michigan as shortwave carrying these along lifts
toward northern WI. Not clear how strong these storms will be able
to be given the current showers/t-storms ongoing over western U.P.
that are working over the atmosphere. Late tonight, attn will be on
the cold front moving in from the northwest. Expect this front to be
over cntrl Upper Michigan late tonight and sweeping past eastern
U.P. on Thu morning. Northwest winds will get gusty behind the front
which will scour out any lingering fog near Lk Superior. Still could
be a higher swim risk developing later in the day for Alger county
due to the strong/northwest winds. Cooler temps especially north
near Lk Superior. Still could reach mid 80s south central with
downsloping winds. At the least, will see a less humid day across
the board.

.LONG TERM...(Thursday night through Wednesday)
Issued at 438 PM EDT WED JUL 4 2018

Models suggest that the broad mid/upper level ridge from the mid
Atlantic to the cntrl Rockies will retrogress and become centered
from WY/CO/UT into the plains from the weekend into next week while
building. With the mean trough position over ern Canada, mainly nw
flow is expected across Upper Great Lakes. Although temperatures
will average near or above seasonal averages, humidities will be
more comfortable with dewpoints mainly in the 50s to low 60s.

For Thursday night into Saturday, high pressure will gradually slide
across the region bringing dry pleasant Summer weather. Highs in the
70s Friday will climb back into the upper 70s and lower 80s Saturday
as srly WAA advection develops.

Sun-Tue, The GFS/GEFS was slightly faster than the ECMWF in bringing
a shortwave across nrn Ontario that will drag a front and
shra/tsra chances through the northern Great Lakes Sunday night.
Dewpoints briefly climbing back into the lower 60s with PWAT
values to 1.5 inches and CAPE values into the 1000-1500 J/Kg range
may support some stronger storms as 0-6km shear values are likely to
be in the 40-50 knot range with the stronger wnw mid level flow over
the area. Some shra/tsra may linger into Monday before high pressure
and drier air again builds into the area.
&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 224 PM EDT WED JUL 4 2018

Line of showers and t-storms will move through IWD and possibly CMX
by mid aftn. VFR conditions should prevail but could be brief drops
to IFR vsby during heavier rain. Small chance that the showers and t-
storms make it to SAW after 21z. Another chance of showers and t-
storms returns to IWD and CMX around 00z and maybe into SAW by 03z.
Higher uncertainly with that chance so just went VCSH for now. Late
tonight into early Thu morning cold front will sweep through all TAF
sites so expect any clouds to clear out quickly on Thu morning. Will
become breeze at all TAF sites on Thu with strongest winds over 25
kts possible at CMX.
&&

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 428 PM EDT WED JUL 4 2018

Winds should remain below 20 knots through most of this forecast
period until increasing to 30 knots Sat night into Sun out of the
southwest as a low pressure system approaches. May see winds 25 kts
late tonight into Thu behind a cold front. Redevelopment of fog will
continue as increasingly humid air moves over the colder waters
through Thursday morning over the west half and Thursday afternoon
over the east half. Fog could become locally dense where rainfall
occurs over the Lake.
