NORTH TEXAS (CBSDFW.COM/AP) – After struggling to dig out from snow and ice that buried North Texas just last week, rain in the Metroplex turned from sleet to snow just before 3 a.m., in some western parts. The winter blast that began February 1 and lasted nearly a week had some municipalities and school districts fearing the worse and canceling classes and events far in advance.

Dallas-Fort Worth International Airport canceled some 120 departures. Spokesman David Magana says DFW airport anticipated operating a full schedule later Wednesday.  Southwest Airlines canceled 40 flights at Dallas Love Field by 8 a.m.

Driving conditions got significantly worse beginning at about 7 a.m. Most roads did not look bad to the eye, but the roads were deceptively slick. The slippery streets caused major problems for many drivers, and by 8 a.m. traffic had slowed to a crawl on many highways.

DART’s train lines were moving slowly Wednesday morning, and its managers added buses to help relieve the congestion on parts of its Red and Blue lines.

Winter Storm Warnings remain in effect for all of North Texas until 6 p.m. Wednesday.

As of 7:15 a.m. CBS 11 Meteorologist Larry Mowry said scattered snow showers are moving into the western sections of North Texas. The activity, which will rotate across the metroplex in the next few hours, includes fine snow. Snow showers will persist through the midday hours.

By 4:30 a.m. the cold front had passed through Fort Worth and the DFW Airport area and was moving through Dallas County.

Temperatures have fallen from the 40s to the teens in both Tarrant and Dallas County. At 7 a.m. the wind chill at DFW Airport was -2. In the city of Dallas the wind chill was 2-degrees and Fort Worth had a wind chill of zero.

As the cold air arrives, there will be a changeover to sleet and snow for a brief period in some sections of Dallas County.

On the radar, the freezing drizzle that is falling in North Texas looks dry. This will create slick roads in the metroplex.

Heavier snow is falling from Jacksboro to Decatur and is now starting to develop in Denton and Cooke County. This activity will shift southeast toward the metroplex after 6 a.m. and increase chances for accumulating snow. Snowfall totals in Dallas and Fort Worth will end up being 1” to 2”, which is less than what was initially forecast, because of the dry slot. However, there may be .10” of ice on surfaces before the snow arrives. In Denton and Collin County up to the Red River, 2” to 4” of snow still looks likely.

Snow began falling late Tuesday in parts of Kansas, the Texas panhandle and Oklahoma, where up to 10 more inches of snow and brutally cold temperatures were expected.

But after the record snowfall that kept students out of school for up to three days, halted garbage pickup and kept some roads impassable, parts of North Texas fearing the worst.
