Winter has finally arrived in Cleveland.

Rapid ice growth is expected on Lake Erie starting Sunday, thanks to frigid temperatures. The whole weekend is looking cold, windy and snowy — unless, like me, you’re spending every day in the cheerful summer escape of the Progressive Cleveland Boat Show.

Here’s what to expect, according to the National Weather Service. See the full marine forecast, from Avon Point to Willowick, here. The Lake Erie water temperature is down to about 34 degrees in some spots.
