While temperatures will warm up by mid-morning, refreezing remains a concern, particularly north of the Metroplex.

Much of North Texas is also under a freezing fog advisory through 9 a.m. Saturday, according to the NWS. Conditions are then expected to improve later in the morning, as the fog starts to clear and the temperatures rise, meteorologists say.

In addition to freezing fog, there is a high likelihood of black ice on roads overnight into Saturday morning, according to the National Weather Service.
