It’s a frosty 3 degrees in Leland with winds whipping powdery snow around and more single digits & high winds driving wind chills far below zero coming over the next couple of days. That’s not optimal for driving, and schools across the county are cancelled. It could, however, bring to life ice formations & caves on Leelanau’s western shore like we’ve seen several times in recent years.
They’ve got past ice cave articles and will be posting updates right here! The Freep reports that Michigan is bracing for potentially record-breaking cold this week:
A polar vortex is forecast to batter the Great Lakes and Midwest regions Tuesday through Thursday, with the lowest temperatures set to occur Wednesday. Some areas of Lower Michigan could face wind chills as low as 45 degrees below zero, according to the National Weather Service.
That would mark the most bitter cold in years for the region.
…The polar vortex is the large area of cold air and low pressure near each of the Earth’s poles. The air flows counter-clockwise near each of the poles, hence “vortex.”
“Many times during winter in the northern hemisphere, the polar vortex will expand, sending cold air southward with the jet stream,” the NWS explains.
