Marine Weather and Tide Forecast for Two Rivers, WI

DISCUSSION
Issued at 257 PM CST Sat Dec 6 2025

Low clouds and scattered flurries were observed across the region this afternoon, except across the far north, where there was some sunshine. Temperatures were much below normal, in the middle teens to middle 20s.

Fast WNW flow aloft will continue through at least mid-week, with a series of clipper-type systems moving through. The first system arrives tonight, bringing a swatch of significant snow from Iowa into northern IL. A southward shift in the system has resulted in lower snowfall totals in the GRB forecast area. Will only carry accumulations of around an inch in our southern tier of counties, with lower amounts farther north. The snow is also expected to depart by daybreak. Parts of northern Wisconsin will not see any accumulation with this system, but developing cold NNW flow off Lake Superior will support an inch or less of powdery accumulation in northern Vilas County late tonight into Sunday morning.
Clearing skies will bring abundant sunshine on Sunday, but also lead to cold temperatures Sunday night, with sub-zero low temperatures expected west and north of the Fox Valley.

Additional Snow Chances through the middle of next week...The next clipper approaches on Monday, with increasing south winds leading to strong WAA during the day. There are differing opinions on whether there will be enough saturation for some light snow development with the WAA, but for now will keep a mainly dry forecast. The low pressure system will impact the region Monday night through early Tuesday, and should bring a swath of 1 to 2 inches of snow to the northeast two-thirds of the forecast area, with perhaps 3 inches over northern Door County. The most impactful clipper system arrives late Tuesday into Wednesday, with strong upper level forcing with a short-wave/upper low and the LFQ of a 120 knot jet streak. In addition, this low will have remnant moisture from a Pacific Northwest atmospheric river to work with. Current probabilistic forecasts show a 30-50% chance of 4+ inches of snow across the forecast area, though the axis of the heaviest snowfall is still uncertain. Headlines are looking more likely during this period.

Precipitation chances become a bit muddled later in the week, so did not budge from the model blended pops. Temperature trends seem a bit clearer. After a mid-week moderation in temperatures (highs in the mid 20s to lower 30s), there is a decent signal for a return to colder temperatures during the latter half of the week.

AVIATION
for 06Z TAF Issuance Issued at 1038 PM CST Sat Dec 6 2025

A mix of VFR/MVFR/IFR conditions late this evening as light snow starts to fall across parts of central and east-central WI.

Light snow will continue overnight, and end early Sunday morning.
Reductions to MVFR/IFR cigs and vsbys will accompany the snow. Up to an inch of accumulation is forecast, highest farthest south (KMTW in the Green Bay forecast area). Most of northern WI will miss the overnight snow, however some light lake- effect showers are possible on Sunday at KRHI.

As the snow departs early Sunday morning, VFR conditions return, with mostly clear skies through the remainder of Sunday TAF period. The exception in far north-central WI, where NNW winds off Lake Superior may keep some lower cloud around throughout Sunday.
Clouds return area wide Sunday night.

GRB WATCHES/WARNINGS/ADVISORIES
