The Perfect Storm

Like Charlie Brown waiting for the Great Pumpkin, iceboaters wait for the Great Zamboni, a rainy weather system that makes the snow disappear off the ice followed by cold that freezes the track. Keep your eyes on Thursday’s weather system because there’s a possibility that Wisconsin could have an abundance of sailable ice.
Where are they sailing this weekend?
Green Lake, WI, Lake St. Clair near Detroit, Michigan, and Ashumet Pond in Mashpee, MA on Cape Cod

From NOAA’s Forecast Discussion: for southern Wisconsin:
The models do show low pressure sliding northeast across Wisconsin
either later Wednesday night or Thursday. The GFS is quicker and
further south with the low track than the ECMWF. Both models do
bring the warm sector into at least southeast Wisconsin during
this period. Thus, it looks like good chances for mainly rain
later Wednesday night into Thursday morning, before cold air
advection brings a transition to light snow southeast across the
area Thursday afternoon into the evening.

This may change, depending on where the low tracks, and would
affect the precipitation types as well. This may have some impact
on travel in northern and western Wisconsin, and perhaps here if
the low track shifts to the south. Cold air advection behind the
low would then bring colder temperatures back into the region for
Friday into Saturday.
