Transcript for Texas Drivers Stuck on Road in Record-Setting Lows
The other big story the weather we saw in that live shot in D.C., the endless winter. Cold blast freezing parts of the country this morning and record-setting lows leaving people stuck on the ice in Texas. ABC's Ryan Owens has that story. Reporter: Texans can only hope this morning's commute will not be a repeat of Monday's which included a 30-mile backup on interstate 45 between Dallas and Houston. Carol Williams and her dog spent Sunday night on the highway. She took this cell phone video during her nearly 16 hours of gridlock. Everyone just shut off their headlights. We all knew we were there for the night. Reporter: Ice and snow causing crashes across the country. Once we get to these 5 degree single dij hit type temperatures it's a real challenge to keep ice off the road. Reporter: In Virginia they're hoping liquid magnesium, so-called super de-icer with a freezing point of minus 26 degrees will keep ice from reforming. Overnight big cities flirting with all-time low temperatures for March. Pittsburgh's record, 1 below. Washington, d.c.'s, just 4 degrees. They get the snowplows out. Reporter: At Reagan airport outside D.C., more than 700 flights canceled in just 24 hours. More than 2900 nationwide.

You're seeing this picture, the trucks off the road freezing rain has been falling for a couple of hours and it's going to be really a wreck anywhere from Austin through Houston and they will eventually warm up but this is the radar from earlier. Just messy stuff. Now I wanted to show you the cold. It is the coldest fat Tuesday for New Orleans since 1989. The windchill this morning, subfreezing all the way south to San Antonio. It's 6 in Chicago. Pittsburgh, 7. Washington, D.C., at 5 and and that warm-up I promised you, milder air is coming. A hint of spring by the end of the week especially on the east coast. Look at Atlanta right up there at 71. Things will be improving, I promise but I told you, josh, when we were talking on the plane yesterday, March doesn't look so good. Let's talk about that.
