On Saturday night, the National Weather Service issued a Winter Storm Warning for Fannin, Lamar, Hunt, Delta and Hopkins counties northeast of Dallas-Fort Worth effective from noon until 9 p.m. Sunday.
Forecasters warn that ice could accumulate up to 1/4 inch and sleet is possible up to 1/2 inch as temperatures plunge through the day.
A Winter Weather Advisory remains in effect for the rest of North Texas from 6 a.m. until 9 p.m. Sunday.
A cold front arrives in North Texas during the predawn hours of Sunday, bringing showers and a few thunderstorms, and then just a cold rain through midday.
But that rain transitions to ice during the early afternoon, ending a little before sunset. Rainfall totals should be less than a half-inch in the Dallas-Fort Worth area.
The temperature numbers are highly dependent on the rain falling at a sufficient rate throughout the morning hours. If the rain is not falling at a significant rate throughout the morning, it is possible we could reach freezing temperatures much more quickly.
Why? The temperatures about 2,000 feet above the DFW area will still be in the 50s while we are dropping into the 30s here at the ground. We desperately need that rain to bring down some of that warm air aloft and keep us from dropping into the 20s prematurely.
If the rain is not heavy enough, then temperatures will drop faster than indicated here, thus transitioning to ice sooner... leading to more significant freezing accumulations.
So with that in mind we will hold to a tenth of an inch of ice in North Texas on Sunday. There will also be some sleet mixed in.
The biggest danger is that bridges and overpasses could freeze up, leading to slippery driving conditions.
Those accumulation amounts will double to the north along the Red River.
There is no chance for snow in our area; that will stay north in Oklahoma, where several inches will fall — especially between Oklahoma City and Tulsa.
Wind chills will be in the teens for most of the afternoon and fall into the single digits late. They may even drop to zero by Monday morning.
We won't get out of the 30s for Monday. We will, however, be back to the 60s and 70s by Thursday and Friday.
