Rapid Ice Formation on Lake Superior

Lake Superior finally gave into the very cold weather with a notable ice shield forming on the northern shore over the past day. Temperatures dropping as low as -45F in Ontario combined with light winds allowed for this rapid formation. With another arctic shot arriving late this weekend, it is currently unclear how much impact the newly formed ice will have on persistent lake effect snow potential for the Keweenaw. More ice would mean less distance available for the cold air to pick up moisture, thus decreasing snow amounts. Stay tuned to later forecasts!
