Below is a live blog that will be updated throughout the day.

3:10 p.m.: I probably should clarify my last post. Although a patch of light snow is moving towards the Metroplex, no significant accumulation is expected as it passes since it will probably be mixed with some raindrops (not frozen) as well.

And for those of you who are weary of winter, we have one more chilly day tomorrow with highs in the upper 40s but with lots of sunshine, and then the 60s reign supreme on Thursday and Friday with 70s for the weekend and maybe even some 80-degree weather in western portions of North Texas on Sunday and Monday.

Unfortunately, there are no signs of significant precipitation to go along with the unseasonably warm weather anytime soon, but there are signals that a storm system will swing through sometime during the last weekend of the month, so stay tuned for updates. - Steve McCauley

2:55 p.m.: The National Weather Service has canceled the winter weather advisory for North Texas.

2:45 p.m.: Most locations in North Texas north of I-20 have climbed above freezing, while areas to the south are running at or slightly below freezing. There will be one more patch or precipitation - mostly in the form of light snow - that will move in from the west and should cover about 50 percent of North Texas, but temperatures should stay above freezing as it passes. - Steve McCauley

1:04 p.m.: Dallas-Fire Rescue Lt. Joel Lavender sent the below statement about the death of firefighter William 'Scott' Tanksley, who was killed by a car that skidded on a patch of ice and knocked him about 60 feet from a bridge onto Interstate 20 last night.

'The members of Dallas Fire-Rescue (DFR) are working through the sudden loss of our brother William 'Scott' Tanksley. Scott was a husband, father, brother and son to his biological family, and we are embracing them and meeting their immediate needs as we move through this sudden and unexpected loss. To the members of DFR Scott's loss is a challenging, our hearts are heavy, however we will press on providing the citizens of Dallas the best service we can.'

1 p.m.:Again, News 8 meteorologist Ashton Altieri takes the floor:

'Based on the current trends we are seeing on radar, most of the wintry precipitation around Dallas/Fort Worth will end before 3 p.m. and all of North Texas should see the precipitation end by 6 p.m. Precipitation amounts will remain extremely light thanks to a shallow but robust layer of dry air in the lowest layer of the atmosphere over DFW.'

12:52 p.m.: Northwest ISD has issued a statement regarding the death of one of its students who was killed in a car accident Monday night. The teen was identified as Katelyn ShyAnn Hooper, a basketball player on the Northwest High School Lady Texans.

'Shyann Hooper was loved by her teammates and school. She will be deeply missed and always remembered as a part of the Lady Texan basketball family,' said head coach Rusty Johnson in a prepared statement. 'Our prayers go out to the families and friends of both young ladies, and we ask for continued prayers for the both families and Brianna's recovery.'

The district was closed today because of the icy weather. Meanwhile, a counseling hotline is set up for students who need to talk about the tragedy. Another student remains hospitalized following that accident. The district did not name him or her.

'We know this is a difficult time for our students and families,' said Northwest High School Principal Jason Childress in a statement.'Shy loved her school and was a faithful part of the school community.She will be missed by many.Tomorrow, we will provide extra counseling staff on campus for students who should need assistance.'

12:38 a.m.: Addison, Burleson, Granbury and Midlothian are reporting freezing rain and freezing drizzle. This will likely continue throughout the afternoon watch out for ice-glazed bridges and overpasses as the afternoon commute gears up.

It looks like the wintry mix should be out of North Texas by 7 p.m.

11:28 a.m.: Yet another dispatch from our always-reliable meteorologist Ashton Altieri:

'Very light freezing drizzle has made a comeback in the DFW area. The radar looks a lot worse than reality because much of the precipitation that is falling from the clouds is evaporating before reaching the ground.

This phenomenon is called 'virga' and is occurring because a dry layer of air is currently sitting above the Dallas/Fort Worth area (up to around 6,000 feet). We expect this dry layer to slowly disappear through early afternoon which means more of the precipitation should be able to reach the ground by 1 p.m.'

10:44 a.m.: Mayor Mike Rawlings has issued a statement on the death of Dallas firefighter William Tanksley, who was killed when a car lost control on a patch of ice and drove into him, knocking him off a bridge and onto Interstate 20 about 60 feet below.

'Dallas mourns the loss of one of our own, Dallas firefighter William Scott Tanksley. As a member of Dallas Fire-Rescue for 14 years, Tanksley dedicated his life to serving the residents of our city in time of need. His death proves what dangerous job our firefighters are tasked with every day. On behalf of the City of Dallas, I extend heartfelt condolences to the Tanksley Family and the entire Dallas Fire-Rescue team.'

10:30 a.m.: Another fatal accident is now attributed to ice, bringing the total to four since the advisory was issued. Tarrant County Sheriff's spokesman Terry Grisham sends word that an SUV lost control on an icy bridge at 5:34 a.m. in the 5500 block of Cattlebaron Drive and hit a tree. The lone occupant died at the scene.

Traffic was closed on the road until 10:15 a.m. Deputies were there within two minutes of the accident, Grisham said.

9:56 a.m.:10 a.m. is upon us and, as the weather models predicted, precipitation will be developing over North Texas through noon. Says Ashton Altieri, News 8 meteorologist, a long band of light, freezing drizzle currently stretches just south of Mansfield out toward Stephenville.

'That long band is going to continue to move north very slowly and, just as we expected, right after 10 a.m. light precipitation is going to start developing,' he said.

Temperatures remain below freezing. There's also a long batch of snow that stretches from the Panhandle all the way to Paris, passing over Sherman and other Grayson County cities. That band will stay north and won't reach the Dallas-Fort Worth Area, Altieri said.

9:41 a.m.: Stephenville is reporting freezing rain and freezing drizzle.

9:15 a.m.: A police report details how Dallas firefighter William Tanksley died on Monday night. He was standing near an accident on 6300 Patriot Parkway, which is the bridge over Interstate 20. It was iced over and a driver heading south on the bridge lost traction on the ice 'as a result of unsafe speed.'

The vehicle, a four-door 2009 maroon Dodge, struck another vehicle and then careened into Tanksley, knocking him 56 feet onto the eastbound Interstate 20 ramp below. He died on the freeway, the report says.

Ice is also suspected of playing a role in the fatal colission on Interstate 20 at Anglin Drive in Forest Hills from overnight. According to Capt. Jerry Cozby, the driver hit a patch of ice and lost control. The vehicle then hit an 18-wheeler and a guard rail, at which point the victim was ejected and run over by a third vehicle. Cozby said the investigation is 'very preliminary' at this time and wouldn't speculate on whether speed was also a factor.

He said detectives are interviewing witnesses Tuesday morning.

8:09 a.m.:Here are some words from News 8 Meteorologist Ashton Altieri, who summed up the conditions the region is staring down heading into the late morning and early afternoon:

'Short-term weather models are coming into better agreement that wintry precipitation will redevelop over the Dallas/Fort Worth area from late this morning into this afternoon. With temperatures staying below or near freezing, we expect a mix of light freezing rain, light sleet and even some light snow.

There will be no sleet or snow accumulation but a light glaze of ice is possible. All the precipitation will end this evening. The biggest travel issues will be on bridges, overpasses, and side roads.'

7:30 a.m.: The fatal Forest Hill accident and the wreck in Dallas near Mountain Creek Parkway and I-20 mentioned in the update about an hour ago have both been cleared.

7:08 a.m.: Dallas-Fort Worth International Airport is reporting 150 total departure cancellations becuase of this weather, says spokesman David Magana. That number could increase as the day progresses, of course.

6:51 a.m.: Granbury and Weatherford Independent School Districts have both canceled classes for the day. We have a comprehensive list of closures at this link.

6:47 a.m.:Good news for folks who had a morning docket at the Dallas Municipal Court: Frank Librio, city spokesman, says jurors are not required to show up because of the inclement weather.

'This includes off docket, proof or plea, pretrial and trial dockets,' Librio says. 'Reset notices will be mailed.'

The city hasn't made a determination on whether to cancel afternoon dockets, however. Also: Dallas has activated its Ice Force Level 1 sanding operation, which dispatches 30 sanding trucks over 250 routes throughout the city.

'Street services will continue to operate ice force sanding operations throughout the morning to facilitate the safe and expeditious movement of traffic for the morning rush and as long as conditions warrant,' Librio adds.

6:27 a.m.:The Interstate 20 corridor between Tarrant and Dallas counties is dotted with accidents. The worst is in Forest Hill, where a pickup truck slammed into a propane tanker at Interstate 20 and Anglin Drive. Matt Zavadsky, the MedStar spokesman, says one person was killed and five others were hurt. The fatally wounded victim was ejected from the vehicle and died at the scene.

Two others were taken to a hospital with minor injuries and three were treated and released. Our Sebastian Robertson says the propane tanker was able to drive away. This was the third fatal accident reported in Dallas-Fort Worth since the Winter Weather Advisory was issued, the others being a Dallas firefighter and a student in the Northwest Independent School District. See the 6 a.m. update for more details on those.

There's also a wreck reported on eastbound Interstate 20 and West Loop 820 near Benbrook. That wreck was not fatal, Zavadsky said, although he was unsure whether there were any injuries. Further east, in Dallas County, a wreck at westbound Interstate 20 at Mountain Creek Parkway is causing delays of at least 10 minutes.

As always, head here to get a heads up on traffic ahead of your morning commute.

6:10 a.m.: Here's what we're working with this morning and afternoon: First of all, expect a dry commute but watch for ice left in the wake of the light rain that fell overnight.

After 10 a.m., a wintry mix looks likely to return to North Texas as an upper-level disturbance moves in from the west. Precipitation will again be light but the freezing temperatures could cause a problem, says meteorologist Greg Fields. The region will likely struggle to make it north of 32 degrees today. Its best chance won't come until 4 p.m., and even then it's not likely to top 34, Fields says.

That gives any sort of precipitation plenty of time to freeze on the roads. However, Texas Department of Transportation sanding trucks are on standby and many cities sanded roads overnight.

6 a.m.:Before 10 a.m., the primary concern for motorists is the light rain that fell overnight and froze on roadways. As always, this is especially true for bridges, overpasses and side roads so exercise caution when traveling on those.

While it didn't rain enough to really measure an accumulation, wrecks are piling up: In Fort Worth, crews have responded to 426 accidents from 4 p.m. Monday to 5 a.m. Tuesday. Plano recorded 60 wrecks overnight, said Steve Stoler, a city spokesman. MedStar, which serves Tarrant County residents, was called to 101 weather-related accidents since 6 p.m. Monday, said spokesman Matt Zavadsky.

Denton County reports no major closures or accidents due to weather.Dallas has not said how many accidents were reported overnight. We do know of two fatal incidents: Dallas firefighter William Tanksley either fell or was knocked from an icy overpass in southwest Dallas last night. The 14-year veteran was at the scene of an accident at Interstate 20 and spur 408 when he fell from the overpass to the concrete. He died from his injuries.

In Justin, a Northwest Independent School District student died and two others were injured in the 2300 block of Texan Drive. Our Todd Unger reported last night that ice was forming in that area at about 5:30 p.m.
