At 7:00 freezing temperatures have moved over all of Collin, Denton and Tarrant Counties. Any precip falling will be frozen, but will also be light.

Dallas County is still above freezing, but temperatures will fall to below 32 by 9am in Dallas
As temperatures slowly fall, any precip with changeover to frozen precip, (freezing rain, sleet or snow).

There are two factors that may keep this from being really a blockbuster event.

The ground temperatures, thanks to our recent warm spell, will keep widespread problems from developing, HOWEVER, bridges and overpasses don’t get the benefit of the warm ground helping keep them warmer than freezing.

Also, any precipitation will be light, of course, even light freezing rain can cause serious icing of bridges and overpasses.With the gusty north winds, any ice accumulating on trees can be blown into power lines, and cause power outages.
