"Ice balls," the strange and chilly weather phenomena, have returned to Lake Michigan as frigid temperatures continue to plague the state.
This time, they were seen by Detroit News photographer Daniel Mears on the shores of Lake Michigan in Frankfort.
The balls of ice form when chunks break off from larger sheets of ice on the surface of the Great Lakes, mix with snow and slush and then are rolled around in the waves.
The ice balls were spotted during another cold winter in 2015 near South Haven.
Last week, another strange ice formation, "ice pancakes" were spotted floating through the Grand Haven channel, as captured by Visit Grand Haven:
And here at home, the Detroit River put on a ghostly show of its own last week, as Detroit News reporter Louis Aguilar captured on Instagram:
As the cold sticks around, we could be seeing more unusual and fascinating ice formations. According to the National Weather Service, subzero wind chills will be common between Tuesday and Sunday, with wind chill reading between 5 and 15 degrees below zero expected.
Tuesday will be mostly sunny with a high of 15 degrees, while lows will get down to two overnight. Wednesday could be our next chance of snow showers, with a high of 15 degrees and a low of 2.
Thursday will get even colder, with a high near 6 and a low of minus-1 overnight. The frigid temperatures continue through the weekend with highs of 4 on Friday and 8 on Saturday. Sunday brings a chance of snow but warmer temperatures, in the mid-20s. Monday will see temperatures that get up to 31 degrees, but again, snow is possible.
