Some organizations in the Dakotas and Minnesota are canceling holiday events as bitter cold settles over the region.
A "Christmas at the Zoo" fundraising event in Minot, ND and "Parade of Lights" events in Yankton and Sturgis are among those being called off.
The National Weather Service has issued a Wind Chill Advisory for wind chill values as low as 40 degrees below zero. Temperatures that cold can quickly freeze exposed skin and cause hypothermia. KSFY meteorologist Shawn Cable is forecasting below zero low temperatures for the next seven days. He says that this could be our longest cold spell in over five years.
The weather service says it's also keeping an eye on possible rapid rises on the Missouri River caused by ice formation.
The cold comes on the heels of heavy snowfall. 6.7 inches was reported in Sioux Falls, 4 inches in Aberdeen, 7.8 inches in Mitchell and 7.5 inches in both Pipestone and Marshall, MN.
