5 Day Ice Discussion...

Continued colder than average temperatures has led to continued ice growth
across the Great Lakes. On Lake Superior, fast ice exists along much of
the shoreline with ice gradually expanding into the open waters. Much of
the central and eastern portion of the lake remain ice free in the open
waters. On Lake Michigan, fast ice exists along part of the southern
shoreline, across Green Bay, and east of Beaver Island, with higher
concentrations of ice also found across most of the nearshore waters.
Much of the central portion of the lake remains ice free. Fast ice exists
on Lake Huron near the Straits, along with Saginaw Bay and across the
southern end of the lake, with high concentrations of ice in all
nearshore waters. Parts of the middle of the lake remain relatively ice
free in the open waters, though this is quickly closing as higher
concentrations of ice expand outward from all shorelines. Much of Lake
Erie is frozen, with fast ice in place across the western basin and along
the southern shoreline. Fast ice covers all of Lake St Clair.

Temperatures will remain cold for Tuesday and Wednesday, with highs in the
10s and 20s and overnight lows in the single digits and 10s, supporting
continued moderate ice growth. A brief warm-up is expected Thursday into
Friday with a period of temperatures in the 30s impacting all of the
Great Lakes, briefly halting ice growth. Colder weather returns into the
weekend, which will allow for moderate to rapid ice growth to resume. A
push of west to northwest winds in the 15-25kt range is expected across
all lakes behind a cold front tonight into Tuesday, which will push ice to
the east-southeast. Generally light winds at under 15kt are expected late
Tuesday through early Thursday. Southwest winds pick up to 10-20kt late
Thursday into early Friday ahead of a strong cold front that will cross
the Great Lakes during the day Friday. Northwest winds will increase to
20-30kt behind the front through Friday night. Shifting of ice is likely
Thursday night through Friday night, first to the north-northeast ahead of
the cold front with a more significant push to the southeast behind it.
