What forecasters said that day

The local office's own words before this small craft advisory 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 small craft advisory went out at Aug 11, 4:08 PM EDT, 1 hour 19 minutes earlier.

Area forecast discussion, Aug 11, 4:08 PM EDT, 1 hour 19 minutes before
Area Forecast Discussion
National Weather Service Marquette MI
408 PM EDT Wed Aug 11 2021

.SHORT TERM...(This evening through Thursday)
Issued at 408 PM EDT WED AUG 11 2021

GOES imagery and RAP analysis show a cold front moving through Upper
Michigan right now with ongoing convection south and east. While CAM
solns are a bit scattered, add'l clearing and heating across the
west and central should aid in some more development after 4. Latest
RAP suggest MLCAPE values between 500 and 1000 J/kg, with 150 SRH
and up to 50kts of 0 to 6km bulk shear. Latest HRRR does suggest
some isolated development as well across the central with GOES-vis
showing some agitated cu, but no reflectivity yet.

Tonight, cold front will move through Upper Michigan bringing some
relief to the humidity values. Upstream in MN, Tds have quickly
fallen into the 40s, with GOES WV imagery showing broad subsidence
as well. Pressure rises and CAA will bring some gusty winds,
especially across the Keweenaw, where some values late
tonight/tomorrow morning will approach 30mph.

Tomorrow, it will be a breezy day behind the fropa tonight with
gusts to around 25 mph across the central, closer to 30mph possible
for the Keweenaw. Waves will increase through the day, leading to
some beach hazards concerns east of Marquette by the evening. Temps
may initially climb through the early aftn, but continued CAA will
begin to cool things off by the evening.

.LONG TERM...(Thursday night through Wednesday)
Issued at 128 PM EDT WED AUG 11 2021

A persistent upper level low will continue to slowly meander over
the Hudson Bay, and eventually move to th east over the north
Atlantic this coming weekend. As this does so, upper level ridging
will become appartent over the central CONUS, ecompassing the Great
Lakes in the process with warmer temperatures. Temperatures will
start off slightly below seasonal average on Friday before gradually
warming to above season normals from the late weekend toward the
middle of next week. Due to the persistent upper level ridge, we can
expect mostly dry conditions for the medium to extended forecast
period as well.

The extended forecast will begin with a cold FROPA exiting the area
by Thursday night across our eastern zones in the cwa, and CAA
beginning to swing down from the north. This will bring much needed
relief with regard to the persistent warm and humid conditions the
Upper Michigan area has observed the last several days. By Friday,
strong CAA aloft via nw flow will keep temperatures very
comfortable. 850mb temperatures will bottom out near 5C over the
Keweenaw, and warm gradually through the day to near 10C. Despite
the cool temperature aloft, the surface high pressure and mostly
sunny conditions will allow surface temperatures to warm into the
60s to lower 70s by late afternoon. This would make the daytime
highs for Upper Michigan on Friday on par with what several areas
have had as overnight lows for the past several days. This will make
it a great start to the weekend as conditions look to remain
tranquil and dry.

Gradual warming because of a building upper level ridge over the
central CONUS will spread to the east to include Upper Michigan, and
the surface high pressure will continue to keep the area dry. Expect
surface temperatures to increase daily through the middle of next
week with daytime highs reaching the upper 70s to middle 80s, and
little to no precipitation to occur.
&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 131 PM EDT WED AUG 11 2021

VFR to brief MVFR conditions are expected at all TAF sites through
the fcst period. Thunderstorm activity is expected to remain just to
the south of KSAW through this evening, but there is a chance an
isolated storm moves over the terminal. LLWS is possible late
tonight/early tomorrow morning as a cold front swings across Upper
Michigan.
&&

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 408 PM EDT WED AUG 11 2021

A cold front passing over Lake Superior tonight will bring some CAA
and pressure rises with gusty westerly winds. While there is some
question as to the stability of the air mass over the lake, there is
a chance for some gale force gusts to around 35 knots along the
Keweenaw Peninsula in north-central Lake Superior late tonight, and
then again tomorrow afternoon. The best chance for this will at the
higher observation platforms. With the cooler airmass aloft,
unstable conditions will help support winds near 20 knots across the
lake through Friday afternoon. From there, high pressure building
into the region is expected to keep winds calm and under 20 knots
into next week.
