Marine Weather and Tide Forecast for Little Sturgeon, WI

DISCUSSION
Issued at 349 PM CST Mon Dec 8 2025

Short Term...Tonight and Tuesday

Ahead of an approaching clipper system, low-level moisture moved into the area bringing low-level clouds and flurries to central and north-central WI this afternoon. Southerly winds have also allowed for low-level moisture/clouds to move inland from Lake MI resulting in scattered flurries across eastern WI this afternoon.
These conditions are expected to continue until the aforementioned clipper system moves into the area this evening and overnight.

While not very strong, this clipper system will spread snow across the region from west to east from late this evening and taper off/end by early Tuesday morning. By Tuesday morning, snowfall amounts of 1 to 3 inches are expected across the entire forecast area. The higher snowfall amounts are anticipated across far northern WI where the better forcing will be located. While there may be minor travel impacts to the Tuesday morning commute on untreated/secondary roads, there is also potential for a brief period of freezing drizzle Tuesday morning, as forecast soundings indicate the loss of ice crystals aloft as the snow is ending.
Therefore, a few spots may become slick Tuesday morning following the departure of the snow. Additionally, gusty southerly winds will accompany the clipper system with gusts to 20 to 25 mph, which will cause reduced visibility at times while the snow is falling.

There will be a lull in precipitation and winds late Tuesday morning through the late afternoon before the next clipper system arrives. During this time, a few breaks in the clouds are possible as high temperatures climb into the mid 20s to low 30s.
The next clipper system will arrive from the west late Tuesday afternoon into the evening, bringing the chance for several inches of snow. For more details, see the long term discussion.

Long Term...Tuesday Night Through Monday

The main focus for the extended will be a passing clipper system Tuesday night into Wednesday followed by much colder air temperatures around the end of the week.

Snow Tuesday into Wednesday...
A strong clipper system is expected to cross into Wisconsin Tuesday, bringing accumulating snowfall late Tuesday afternoon and Tuesday evening. The timing/location for the heaviest snowfall will likely be Tuesday evening in an area just north and east of the upper low Tuesday evening, but this will likely be a relatively narrow band compared to the overall snowfall. As a result a widespread 3-4 inches seems likely with a narrower band getting closer to 5-7 inches. As model certainty remains low on the location of this higher band, maintained the watch over the region this forecast issuance. Would expect the current Winter Storm Watch covers more counties than will ultimately see a warning, given the above info. On the backside of this system Wednesday, expect strong cold air advection to continue snowfall into Wednesday morning and stronger winds by the late morning to afternoon period. Wind gusts up to 20 to 30 mph at times will allow for some drifting snow in open areas during the day Wednesday. Drier air will ultimately bring an end to the snow for most Wednesday afternoon.

Cold...
Much colder air moves in behind this system, starting Wednesday night through the early weekend. Overnight low temperatures will see a downward trend from a few degrees above zero Wednesday night to below zero across the whole area Friday and Saturday night.
Saturday high temperatures are expected to only be a few degrees above zero for much of the area. Wind chills in the coldest parts of the weekend may also reach as low as -10F to -30F at times.

AVIATION
for 00Z TAF Issuance Issued at 538 PM CST Mon Dec 8 2025

MVFR flight conditions were observed over NC/C WI at issuance time, with VFR conditions in the east. Patchy flurries were reported in many areas. Regional radar showed a large area of light to occasionally moderate snow approaching from Minnesota, in association with a clipper low pressure system.

The quick-moving clipper system will bring accumulating snowfall, reduced vsbys, and widespread IFR conditions to the area from west to east late this evening into the early overnight hours.
General arrival times at CWA/AUW/RHI should be around 04z-05z/Tue, and around 06z-07z/Tue at the east central WI TAF sites. By early Tuesday morning, 1-3 inches of snow is forecast over the area, with the highest amounts expected along and north of Hwy 29. As the snow ends late tonight/early Tuesday, a period of light freezing drizzle and IFR conditions may occur for several hours in central and east central WI. A gradual improvement in flight conditions is expected during the late morning and afternoon, though light snow is poised to return to central WI (including AUW/CWA) toward the end of the TAF period. Widespread significant snow will overspread the area Tuesday evening as a strong low pressure system arrives.

Southerly winds will increase this evening with gusts to 15 to 20 kts. A period of LLWS is expected at AUW/CWA/GRB/ATW later this evening into the overnight hours, as southwest winds increase to 35 to 40 kts just above the surface. Surface winds will turn westerly late tonight into early Tuesday.
