.DISCUSSION...
Issued at 152 AM EDT Sat Jun 13 2026

GOES Water Vapor imagery and RAP analysis highlight a broad upper
level low rotating over northern Ontario this morning, with multiple
impulses embedded within the flow. A cold front is currently
analyzed upstream in Minnesota pressing eastward, while a swath of
isentropically forced rain is moving eastward through northern
Wisconsin and Menominee County. GOES GLM has observed a few
lightning flashes, but its been primarily flash free for the past
hour. Mild temperatures have been observed across the forecast area
so far, with most areas removed from the immediate Lake Michigan
lakeshore dipping into the 50s. Those by the lake have hovered in
the 60s so far. For the remainder of the night, shower activity will
continue moving into and through Menominee County, with perhaps an
isolated shower developing north across middle Upper Michigan. By
morning, CAMS and current trends suggest shower activity will be
focused into eastern Upper Michigan, before a break in precipitation
by mid-morning. Temperatures may dip a few degrees, but most
locations will only cool as low as the low 50s.

Today, the upstream cold front will press west to east through the
forecast area. Dinurally driven instability will help restart shower
and thunderstorm activity in eastern Upper Michigan by afternoon
while dry conditions prevail in the west half. Gusty winds will
develop with daylight and cold air advection aloft in the west half
though. Current thinking is for widespread 20-25 mph westerlies,
with winds 30-35mph in the Keweenaw. These elevated winds will
result in dangerous swimming conditions for beaches in Alger County
by afternoon and a Beach Hazard Statement has been issued.

Winds will lighten this evening while a cooler airmass settling
over the region kicks off a few days of below normal temperatures.
Latest guidance continues to suggest Sunday highs will peak in the
low to mid 60s, except closer to 70 by the Bay of Green Bay. These
daytime highs will warm into the mid 60s to low to mid 70s for a
majority of the coming week. Overnight lows in the 40s will be
widespread away from the lakeshores. A weak wave moving through
Sunday morning may support early light rain, but the next best
chance for rainfall comes Monday afternoon/evening in the west half
thanks to another shortwave rotating through the broad trough aloft.
Thereafter, daily rain chances return for the Great Lakes but
differences in the track/location of each wave suggest lower
confidence. There does continue to be indications of a widespread
moderate to heavy rainfall event moving through the Great Lakes
region Wednesday night into Thursday. Latest ensembles suggest
primary risk being to our south though.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1254 AM EDT Sat Jun 13 2026

Expect VFR conditions to prevail through the day on Saturday as mid
level cloud cover gradually increases. A weak cold front will cross
the area this afternoon and bring a slight chance of showers, but
probability is low enough as to not warrant inclusion in the TAFs at
this time. Southwest winds will pick up again after sunrise on
Saturday and eventually veer west-northwesterly while gusting to 20-
25 kt at KIWD and KSAW and 30 kt at KCMX. Ceilings will continue to
gradually lower through the end of the period and have a 70% chance
(per HREF) to reach MVFR at KIWD and a 50% chance at KCMX by 06z
Sun.

.MARINE...
Issued at 152 AM EDT Sat Jun 13 2026

Elevated winds near 30kts develop today in the vicinity of the
Keweenaw Peninsula and northward toward Isle Royale ahead of a cold
front moving through the region. After the frontal passage, winds
settle to near 20kts or less through midweek; although daytime winds
may increase to near 25 kts near the lakeshores Sunday afternoon.
