The first winter storm of the season has left North Texas, but cold temperatures have frozen the water and slush that remained on the ground. TxDOT and cities have been working to clear ice from the roads, but there are still dangerous road conditions.

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.

Any snow and ice that melts Friday is likely to refreeze overnight, and black ice could be a danger, according to the NWS.
