Lake Mendota has officially frozen over, after a long warm spell that left many wondering when (and if) the lake would ever freeze.
After a cold front drove temperatures below zero over the weekend and winds died down, Lyle Anderson, office manager at the Wisconsin State Climatology Office, knew the conditions were right for “instant ice.” Residents may have noticed a “steam fog” hanging over the lakes, created when cold air moves over warmer water, also a “harbinger of freeze.”
