Today another lead became evident, opening between Black Cat Shoals and Three Mile Island. Once it opens, it will form a water channel between Black Cat and Three Mile, with the shoals as a midpoint.

This is important because the strongest and most frequent wind in this area (NW and SE) runs perpendicular to where the lead is setting up (SW to NE). The wind will be able to widen the crack on both sides and tear the ice right out if we get a windy storm.

Also today, the surface temp at Black Cat WeatherCam went to 35 for the first time since ice-in. This was in response to the depth temp (10 feet) rising to 35 in the last 24 hours after remaining at 33/34 all winter. Both temperatures are now equal at 35. The water is quickly working its way toward its non-winter pattern in which the surface is warmer than underneath.

Tomorrow may be a minor set-back as snow falls on the water surface... this usually has a cooling effect that may result in some weak re-freezing of open areas.
