For the second time in nearly three weeks, winter weather has forced the cancellation of classes at the University of Northern Iowa in Cedar Falls.

A notice posted on the university's website Wednesday morning said that UNI would be closed for the remainder of the day and only essential personnel should report to campus. University officials also shared the notice on Facebook.

Several locations in northeast Iowa reported receiving snowfall amounts ranging as high as 4-6" Wednesday morning. Waterloo, Evansdale, Fayette and Randalia were among the places that had received 4" since Tuesday night. Independence and Vinton both reported 5" of snow, while 5.4" fell in Cedar Falls. The greatest totals were reported in Chickasaw County, where Ionia and New Hampton both received 6".

A Winter Storm Warning was posted for counties generally west of a Decorah-to-Oelwein-to-Cedar Rapids line until noon Wednesday. A Winter Weather Advisory continued until 6 PM for counties east of the line to the Mississippi River. An additional 2-4" of snow was expected through noon, followed by patchy freezing drizzle.

The winter weather forced most school districts across northeast Iowa to cancel classes on Wednesday. Officials at Upper Iowa University also decided to close the main campus in Fayette for the day, after initially announcing a 12:30 PM delayed opening.

Classes were held, as scheduled, Wednesday at the University of Iowa and Iowa State University. Both institutions, along with UNI, closed their campuses for all or part of three days in late January when temperatures across the state plummeted to the coldest on record in more than 20 years.
