FORT WORTH (CBSDFW.COM/AP) – The sleet and snow have stopped falling in parts of North Texas, after a frigid wintry mix came down across the Metroplex through the lunch hour Tuesday.

The heaviest sleet and snow fell in the western sections of the Metroplex, like Tarrant County and Denton County. Roads will remain slick as the temperatures continue to fall below freezing.

The treacherous weather prompted numerous closings and delays across North Texas. The storm briefly closed Dallas-Fort Worth International Airport. After runway deicing and treatment, the airport reopened just before 8:30 a.m. As of 1 p.m. DFW Airport had cancelled some 500 flights. Airport officials are advising everyone to check flight status at

Airport spokesman David Magana says crews continue to work to keep runways clear.

American Airlines spokesman Tim Smith says about 800 flights, headed out of and going in to, DFW were cancelled. Systemwide the Fort Worth-based carrier had some 1,400 cancellations.

DART Rail service was also suspended. Officials with DART say workers were busy for much of Tuesday trying to restore service, and were hampered by continuing precipitation and high winds.

DART buses operated slowly due to road conditions.

In Fort Worth, the TRE had minor delays.

Between Midnight and 8:00 p.m. Dallas police Officers responded to 95 minor accidents and 52 major accidents. DPD referred more than a dozen other accidents to the Dallas County Sheriff’s Office. Since midnight, the Fort Worth police Department responded to 240 accidents, and Plano has handled 42 accidents. Keep in mind the number of accidents responded to by police is in no representative of the number of actual accidents that occurred on North Texas highways and byways.

The area’s largest school districts — including Dallas, Fort Worth and Arlington — canceled classes again for Wednesday.
