Area Forecast Discussion
National Weather Service Marquette MI
335 PM EDT Tue Jul 6 2021

.SHORT TERM...(This evening through Wednesday)
Issued at 335 PM EDT TUE JUL 6 2021

Rain showers have made their way into parts of the west before noon
this morning and have progressed eastward into parts of the north-
central. These showers are tied to an upstream shortwave over the
Dakotas and surface cold front. Moisture convergence ahead of it in
proximity to a stalled frontal boundary to our south and right jet
entrance region will allow for these rain showers spread over the
area as they continue progressing eastward this afternoon and
tonight. With almost all of the instability to our south, fgen
appears to be the primary driver, and could be strong enough to
support a good soaking. Guidance varies through tomorrow morning,
but generally 0.5 to 1.0 inches of rain is expected across the south
half of Upper Michigan with a progressive gradient northward toward
the Lake Superior lakeshore. Tomorrow the rain will persist across
the south and parts of the east.

With the passage of the cold front, cooler temps are expected.
Overnight lows tonight should be in the upper 40s in the interior
west, mid 50s in the far south, and near 50F elsewhere; highs
tomorrow should largely be in the 60s, with some high 50s possible
near the immediate Lake Superior lakeshore.

.LONG TERM...(Wednesday through Monday)
Issued at 346 AM EDT TUE JUL 6 2021

Models suggest that the pattern will amplify slightly through the
week as ridging builds over the western CONUS into western Canada
with downstream troughing into eastern Canada, the Great Lakes and
the northeast U.S. After a cool down into Wednesday, temps will
rebound near seasonal averages by the end of the week/weekend.

Beginning Wednesday, precipitation from yesterday's system should
end with the exception of some lingering showers south central in
the morning. Skies will clear from the north in the wake of the
system. It will be chilly again with continued CAA under a fairly
stiff northeast wind off Lake Superior. Expect highs from around 60
north to the mid 60s south.

Thursday-Sunday, Recent model runs and ensembles have trended
farther south with the shortwave and associated sfc low for the end
of the week with a quasi rex block setting up by the end of the week
for the Western Great Lakes/Central Plains region. Our area will be
on the north end of the block, influenced more by upper ridging. So,
would expect the a mostly dry fcst for Upper Mi for the end of the
week/weekend. Temps will trend toward back toward seasonal normals
for the late week period.

Monday-Tuesday, Deterministic models and ensembles indicate rex
block breaking down with its weakened low lifting ne with the
prevailing upper level flow into the Upper Great Lakes. This remnant
low/shortwave could bring some isolated to scattered showers back
into the fcst area. Coverage of showers could be enhanced a bit by
diurnal heating/instability, especially by Tuesday.
&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 129 PM EDT TUE JUL 6 2021

Rain showers are expected to spread over Upper Michigan this
afternoon. Impacts are most likely expected at KIWD and KSAW, where
some moderate rain may reduce visibilities into this evening.
Guidance is a little mixed on ceilings falling to IFR, so bottomed
ceilings at low end MVFR for the time being with gradual improvement
tomorrow morning. KCMX is expected to remain VFR, with light showers
expected to end early this evening.
&&

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 335 PM EDT TUE JUL 6 2021

Northerly to northeasterly winds up to near 20 knots are expected to
persist this afternoon and evening. Tonight, northeasterly winds
across the lake will begin increasing to 20-25 knot range and begin
settling down by afternoon when a high pressure moves over the lake.
Under this high, winds should remain light through the remainder of
the week and into the weekend.
