Marine Weather and Tide Forecast for Egg Harbor, WI

DISCUSSION
Issued at 105 PM CST Tue Feb 10 2026

Northwest winds in the wake of a cold frontal passage this morning may produce light lake effect snow across far north-central WI through this evening, but expect any accumulation to be minimal.
High pressure building over the northern Plains will then slide east dominating the region through the end of the work week. LREF mean 500mb flow does show a subtle short-wave over the Upper Mississippi Valley Thursday which does bring a ~10% for light snow to central WI Thursday morning, however, the better chances for accumulating snow are further west along the WI/MN and WI/IA borders. Another low-end 10-15% chance for light precipitation comes Sunday as a low develops over the southern CONUS.

Temperatures will begin to trend warmer than normal Thursday and by this weekend there is a 50-80% chance for highs above 40 degrees.
There is a 30-50% chance that areas south of HWY 29 reach 50 degrees by early next week. The warming trend will lead to a quickly melting snowpack and deteriorating ice conditions which does raise the concern for ice jams next week. Additionally the melting snowpack will lead to an increase in low-level moisture increasing the possibility of periods of fog this weekend and next week.

Long-range ensembles and ML models are showing early signals for a more widespread precipitation event during the early part of next week. Forecast soundings have a large spread in temperatures at this time making it very uncertain if this would be a snow, rain, or wintry mix even.

AVIATION
for 00Z TAF Issuance Issued at 524 PM CST Tue Feb 10 2026

Strong subsidence and downsloping NW winds were eroding the low cloud deck across the central part of the forecast area early this evening. While clouds may be more persistent due to lake-enhancement across the far north, it appears that the rest of the region will scatter out this evening. Have gone more optimistic with the clearing trend and subsequent improvement to VFR over most areas.
Otherwise, northwest winds will gust to 20 to 25 kts tonight into Wednesday, with a decreasing trend expected toward sunset.
