Airport officials reported that airlines proactively canceled about 180 flights Monday, on top of 300 the day before.

That forced a tour group of about 50 travelers to split up and fly into alternative airports before linking up in New York to fly to Madrid. Still, they were grateful for the advance notice, and lack of serious icing Monday. - Reporter Jim Douglas

'It's going to be a long, long day,' they said at 3:30 a.m., waiting in Terminal C for ticket counters and the security checkpoint to open. The180 canceled flights represents about 20 percent of daily departures from DFW Airport.

4:00aIt will be mainly rain around the DFW area through the morning commute.

Most roads will simply be wet but icy spots are possible especially on bridges and overpasses. - Meteorologist Ashton Altieri

8:01p The National Weather Service has downgraded the Winter Storm Warning to a Winter Storm Advisory, effective until noon Monday. Sleet and ice accumulations will create hazardous travel conditions along streets and highways, especially on bridges and overpasses. Ice accumulation is expected to be less than a quarter-inch. - National Weather Service

6:56p More than 300 flights were canceled Sunday at Dallas-Fort Worth International Airport, representing about one-third of the scheduled departures.

5:31p It looks like the Monday morning commute could be tough in some areas; it all depends on the temperature. We won't have much in terms of precipitation on Sunday evening. At midnight, the precipitation should start to pick up. It all depends on what the temperature is it could be rain, sleet or freezing rain. Bridges and overpasses may have very slick spots during the morning commute. - Meteorologist Ashton Altieri

Areas of rain, freezing rain and sleet will re-develop across much of North Texas by late evening, and persist through daybreak on Monday. With temperatures hovering at, or slightly below freezing through daybreak, some accumulations of sleet and/or freezing rain will occur.

1:20p I have received a lot of questions about the difference between sleet and freezing rain. Sleet is an ice pellet that bounces when it hits the ground. It usually does not cause much problems unless it comes down heavily or in combination with freezing rain.

Freezing rain, on the other hand, is a totally different phenomenon. Freezing rain is ordinary raindrops that don't freeze until they actually hit something, and then they freeze on impact. This leaves a glaze of ice on objects and is much worse. Since most of our precipitation today should be sleet, that makes for better driving conditions.

But again, you never know when you might get that brief changeover to freezing rain, so be cautious on elevated surfaces like the bridges and overpasses. - Chief Meteorologist Pete Delkus

12:51p Lots of reports of rain mixed with sleet across the entire area. Only impacts so far are slick spots on elevated surfaces. - National Weather Service

12:49p In anticipation of winter precipitation, airlines at Dallas-Fort Worth International Airport have pre-canceled about 300 departures to reduce the number of stranded travelers.

12:21p Dallas prepared for the onset of ice by declaring 'Ice Force Level 1,' code for sending 30 sanding trucks to trouble shoot hazardous road conditions. Officials at Dallas-Fort Worth International Airport held a flurry of conference calls and meetings to prepare for the first wintry blast. Some flights are expected to be canceled, airport spokeswoman Cynthia Vega said. - Associated Press

12:10p The latest radar images show mixed precipitation falling over much of North Texas, including snow, sleet, freezing rain and rain. - WFAA

11:50a Many areas are already at or below freezing to the west of Fort Worth; that's where the mixed precipitation is falling. - WFAA

11:10a We're seeing some slick roads to the north and west of Dallas-Fort Worth where the mixed precipitation has started falling. - WFAA


Our first round of wintry mix is headed this way. Most of this is rain and sleet with pockets of freezing rain. Even a few snowflakes could occur.

A Winter Storm Warning issued by the National Weather Service begins at noon Sunday and continues for the next 24 hours. Travel could be severely impacted by icy roads, particularly during the Monday morning rush hour.

Temperatures were above freezing in Dallas-Fort Worth on Sunday morning, but may drop to freezing as soon as the precipitation begins. And then the temperatures should go back above freezing this afternoon with a continuation of rain and sleet and even some wet snowflakes.

The bulk of this mostly light precipitation for North Texas will occur from 10:30 a.m. through 5 p.m.

The second wave of precipitation will arrive after 9 p.m. Sunday, becoming moderate to locally heavy after midnight. This wave will be more significant in terms of amounts especially for the southeast half of North Texas.

And we will address the potential for ice accumulations with this second round in our afternoon discussion. And yes, I realize the maps I posted last night are downplaying this entire event, but please remember that a miscalculation in the temperature by 1-degree on my part is enough to cause this event to be more significant than what I posted. - Chief Meteorologist Pete Delkus
