Area Forecast Discussion
National Weather Service Marquette MI
155 PM EDT Fri Jun 5 2026

.KEY MESSAGES...

- Scattered showers and thunderstorms develop into the late
afternoon, continuing west to east into tonight. A few storms could
be strong in the afternoon and evening. Rainfall amounts will range
from a quarter to a half inch across much of the area through this
evening.

- Hotter weather returns into next week, with another round of
showers and storms Monday. Diurnally-driven showers and storms will
be possible the remainder of the week (15-30% chance each day).

&&

.DISCUSSION...
Issued at 155 PM EDT Fri Jun 5 2026

Afternoon surface analysis places broad low pressure right over Lake
Superior, with a trailing cold front exiting the Arrowhead of MN.
The UP thus remains in the warm sector. Skies have cleared out
across much of the area in the wake of morning showers, with the
exception being the eastern UP where lower stratus continues to
stream off of Lake Michigan. Still, Day Cloud RGB reveals some
agitated cu developing over the central and western UP, excluding
the Keweenaw and western Ontonagon and Gogebic counties. There, I
suspect onshore flow is leading to a more stable airmass. More
inland, RAP analysis reveals SBCAPE as high as 1500-2000j/kg and
steep lower-level lapse rates, and a few cells are already starting
to pop over the central UP. Storms should increase in coverage over
the next couple of hours, and bulk shear increasing to 20-30kts
could help sustain updrafts and lead to a stronger storm here and
there. Hail and gusty winds would be the main threat. Keep an eye on
the skies heading into your Friday evening! Given PWATs as high as
1.5in, brief, heavy downpours are not out of the question, and will
note that CAMS also indicate a potential for some training to occur
before the cold front sweeps through later tonight. A general
quarter to half-inch of rain is expected over much of the UP through
the first half of tonight, but higher totals even up to an inch are
not out of the question where heavy downpours or multiple rounds of
storms can occur (50% chance).

Most showers should exit the region by the overnight hours into
Saturday, leaving a mostly dry day except for a few lingering
showers in the far east early Saturday morning. With building 500mb
ridging over the Great Lakes this weekend, expect a warming trend as
temperatures climb back into the mid 80s inland of the Great Lakes
by Sunday, though weak surface flow under a surface high will keep
lake breezes and cooler shoreline highs in the forecast. Beyond
Sunday, ensembles struggle about the details, with various clusters
of surface features, but the broad pattern of ridging centered over
the Ontario/Quebec line and troughing over the West Coast will put
the UP in southwesterly flow aloft with various shortwave features
emerging from the base of the large-scale trough over the Rockies
providing some opportunities for diurnally-boosted minor
shower/thunder chances (~15-30%). The ridging and persistent warm
southerly flow will keep the warming trend continuing, with the NBM
suggesting some mid to upper 90s highs in the interior west in the
mid- to late-week, though raw guidance suggests highs in the mid 80s
instead, so it is to be determined whether the NBM bias correction
is overcorrecting or if the hottest airmass of the season to date
will be upon us.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 132 PM EDT Fri Jun 5 2026

Showers and thunderstorms fill back in as a front crosses the area
this afternoon and instability increases with daytime heating.
Expect -TSRA to remain south of KCMX, ending at KIWD by around 00z
Sat and KSAW by around 04z. IFR/LIFR fog and cig restrictions will
be possible at CMX and SAW, though, early tomorrow morning in the
wake of any convective activity.

&&

.MARINE...
Issued at 155 PM EDT Fri Jun 5 2026

A low pressure passing north of Lake Superior today will bring up to
35% chances of some thunderstorms, but otherwise will not be strong
enough to kick up wind gusts of 20+ kt. Otherwise, satellite and
available webcams reveal areas of fog over the western arm of the
lake, which should spread eastward into tonight with the passage of
a cold front. With high pressure reestablishing over the weekend,
winds remain light until Sunday afternoon, when east/northeast winds
pick up to around 20kts over the western portions of the lake ahead
of another approaching low pressure. Guidance takes this over the
area Monday, and brings a 50-70% chances of 20+ kt gusts especially
in the east to central portions of the lake. Winds fall back after
Monday, but may pick up again late next week as low pressure moving
out of the Rockies leads to a tightening pressure gradient over the
Great Lakes.
