The second snowfall of the month in Dallas hardly resembles the first.

Flurries are expected until early afternoon, but there won't be much more to today's snows than that -- at least not north of Interstate 20.

Early this morning, forecasters with the National Weather Service were predicting an inch or two of snow, with more than twice that amount expected in the southern reaches of the metropolitan area.

The 30-year-old record for snow in a winter is unlikely to fall today. Dallas is within 2 inches of that record. The official recording station is at Dallas/Fort Worth International Airport.

Even though today's weather won't remotely resemble the 12-inch snowfall earlier this month, road and utility officials were taking precautions. Sub-freezing temperatures tonight could make some roads hazardous.

Crews from the Texas Department of Transportation, the North Texas Tollway Authority and area cities were out in force before dawn, loading trucks and treating roads and highways as needed.

TxDOT sent crews out between midnight and the morning rush-hour to lay magnesium chloride where snow typically builds up, spokesman Mark Pettit said.

“We have about 10,000 miles of roads to prepare, and there is no way to cover all of that,” he said. “So we put it on bridges and overpasses.”

Most of the storm is passing to the south of Dallas. Areas from Palestine to Waco are expected to see 3 to 5 inches today.

Even so, American Airlines canceled more than 100 flights today at D/FW Airport, spokesman Tim Wagner said.

The temperature in Dallas should hover around freezing through most of the day, before dropping to the upper 20s overnight.

Snowfall is not expected again for the rest of the week. High temperatures are expected to reach the 50s Wednesday and the 60s Thursday.

Oncor Electric Delivery continues to monitor the weather and has crews on standby in the event of power outages, said Jeamy Molina, an Oncor spokesman. More than 200,000 customers lost power during the Feb. 11 snowstorm.

The winter snowfall record of 17.6 inches was set in the winter of 1977-78. North Texas has seen 15.7 inches this winter, including a record 12.5 for February.
