Dallas-Fort Worth temperatures are expected to dip below freezing overnight, potentially creating icy conditions Wednesday.

With frigid weather predicted to persist into the middle of the week and roads thawing slowly, North Texas school districts, including Dallas, Denton and Fort Worth, began announcing closures for Wednesday.

Most school districts and colleges either canceled classes or shifted them online Monday and Tuesday, as roads remained slippery. Most interstates and highways had several lanes cleared, according to Texas Department of Transportation’s cameras. On most neighborhood streets, ice and snow remained a hazard.

While temperatures are expected to dip back into the low 20s overnight, potentially creating icy conditions Wednesday morning.
