.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 223 PM EST Sat Nov 15 2025

Pattern Synopsis:

Strong troughing and accompanying embedded jet max will punch over
the Great Lakes this evening into Sunday, providing strong forcing
aloft to quickly deepen a cyclone below 990mb as it treks across far
southern Ontario and over New England by Sunday morning. Upstream
ridging will build surface high pressure down across the heart of
the continent, placing northern Michigan squarely between the two
features on Sunday with persistent northwest flow.
Aforementioned troughing and surface cyclone will work further
east Sunday night as building high pressure begins to nose into
the region by Monday morning.

Forecast Details:

Ongoing light showers will exit to the east over the next few hours,
leaving a break in precip chances later this afternoon and evening.
Strong northwest winds will continue to overspread northern Michigan
as the cold front slides out of the area, bringing much cooler
temperatures and kick starting lake effect snow showers later
this evening and tonight. Chances begin across the eastern U.P.
first, and eventually across northern lower later tonight.

The primary focus will be the potential for quick drops in
visibility and hazardous travel conditions due to the combination of
falling snow and strong winds. A relatively dry background
environment, activity beginning at night, and strong winds in place
is expected to organize activity into a few dominant bands that
focus over localized parts of the Northwoods with little snowfall
between these areas. Highest totals of 3-6 inches are expected
across western Chippewa and eastern Mackinac counties with locally
higher amounts possible should dominant banding lock in for an
extended period of time later tonight and Sunday. This band is
expected to stretch into far northeast lower, dropping around 1 to 2
inches across areas there. Lesser amounts of 1-3 inches are expected
across northwest lower where another dominant band is expected to
set up through the day tomorrow. As stated above, amounts are
expected to be secondary as the potential for quick drops in
visibility with falling snow and winds may lead to hazardous travel
conditions -- especially on roadways exposed to strong winds. A
winter weather advisory has been issued for parts of the eastern
U.P., and a future advisory may need consideration for northwest
lower should confidence in hazardous travel impacts in this area
increase -- despite lesser snowfall amounts. Snow chances will begin
to taper off heading into Monday as dry air begins to work into the
area.

.LONG TERM /MONDAY THROUGH FRIDAY/...
Issued at 223 PM EST Sat Nov 15 2025

Expansive troughing will continue to pivot over the northeast CONUS
and Canadian Maritimes on Monday as the system becomes increasingly
vertically stacked with time. Meanwhile, ridging sliding over the
Great Plains will help build the axis of surface high pressure over
the Great Lakes heading into Tuesday. This will create an
increasingly hostile environment for any ongoing lake effect snow
showers Monday morning as the low-level airmass dries out and flow
weakens, and in turn will lead to activity diminishing through the
morning and afternoon. Primarily precip-free weather appears likely
through the middle of the week as said high pressure settles in.
Temperatures also look to gradually warm throughout the week with
highs in the mid to upper 40s for most by Thursday. Rain chances
look to return to northern Michigan by Friday as the next system
begins to work into the region.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1235 PM EST Sat Nov 15 2025

Mix of IFR/MVFR CIGs will persist for the next few hours, especially
across northeast lower and eastern upper Michigan. Conditions are
expected to rapidly improve from west to east this evening as the
front slides through, bringing a return to VFR conditions across
northern Michigan. There is potential for MVFR CIGs to return to
parts of northwest lower and eastern upper late tonight and Sunday
morning as lake effect snow showers develop. Primary concern with
this activity will be significant drops in visibility due to
combination of falling snow and strong northwest winds that will
gust to 25-35 kts at times. CIU and PLN will have the best chances
to experience IFR/LIFR VSBYs for brief periods during the issuance
period, but overall worst impacts are expected away from northern
Michigan TAF sites at this time.
