Michigan’s Upper Peninsula is locked in a deep freeze this morning, where freezing fog hangs low over Lake Superior and drifts across US-41 in Marquette. Temperatures sit at 12 degrees, and visibility has dropped to a quarter mile at times. Frost clings to guardrails and bridge decks.
Freezing fog remains the main concern through mid-morning. Moisture settles onto cold pavement and may create slick patches, especially on elevated roads. Slow down and allow extra braking distance if you’re heading out early.
Skies turn mostly sunny later today, and highs climb to around 40 degrees. Southwest winds increase to 10 mph with gusts near 15 mph. That mild February rebound helps melt icy spots by afternoon.
Tonight falls to 27 under partly cloudy skies. Sunday starts with patchy fog before sunshine returns. Highs reach 36 degrees with light northwest winds.
President’s Day brings partly sunny skies and another high near 40 degrees. It feels manageable for mid-February. Monday night dips to 24 as clouds increase.
By Tuesday, highs ease back to 34 with partial sunshine. Snow showers likely develop after 1 a.m. Tuesday night. Lows settle near 27. Wednesday stays cloudy with snow showers likely and highs around 31. Additional snow chances linger into Thursday and Friday, reinforcing winter’s grip across Upper Michigan.
Meteorologists are tracking this midweek system closely. Even light snow can turn slick quickly after mild afternoons, leading to flash freezing on untreated surfaces.
Long-range trends hint at a gradual moderation later next week, but winter is not done yet in Marquette.
