The region was encrusted in a 4-inch-thick layer of ice, and North Texans wanted to know why city and state leaders weren't doing more to clear the roads.
"This state needs to invest in more plows," one woman wrote on Facebook. "So disappointed in how my tax dollars are spent."
"Why the hell wasn't this done yesterday?" another woman wrote from her
But what more could have been done?
As it turns out,
In the hours before the storm hit, some forecasters worried behind the scenes that the region could be ground zero for a power outage that would affect 1 million people.
Still, the storm was one of the fiercest to hit the region in years, shutting down much of daily life. With roads buried in ice slick enough for figure skating, schools shut down, shopping malls became ghost towns, and grocery stores were emptied of bread and other perishables.
Now that much of the ice has thawed and things have returned to normal for most North Texans, officials from agencies responsible for the roads are fighting for their reputations.
Instead of once again taking the heat (pardon the pun) for their inability to manage weather-related traffic jams -- including the
"I think everybody can see, in spite of our uninformed friends in the media, that beginning Thursday evening [
Despite the complaints, they say they were aggressive in fighting the storm, even though they didn't fully understand what they were up against until just hours before the sleet began to fall.
Officials from the
"What TxDOT is facing is not a simple process," said
Loss of power, or roads?
What complicated matters during preparations was uncertainty over whether the storm would become a disaster marked by the widespread loss of electricity or of traffic mobility, Bradshaw said.
Initially, meteorologists feared that freezing rain would blanket the
"We were uncertain how deep the cold air was going to be, and that's the determining factor on whether you have freezing rain or sleet," Bradshaw said "Given the amount of liquid in the storm, we were really worried we were going to have an awful lot of ice. We thought there was the possibility of more than half an inch."
The weather service was feeling gun-shy, he said, after forecasting an ice event the week before that failed to materialize.
"People get desensitized to forecasts, particularly if you whiff. You have got to hit these things, so we wanted to be very careful," he said.
So, beginning three days before the bad weather arrived, Bradshaw pulled together 10 to 15 fellow meteorologists for a wide-ranging group discussion on issuing a forecast. During that week, the
"We really drilled down on things to reach a better consensus on where we were going," he said. "The two hardest things to predict in weather are winter precipitation types and how much precipitation you are going to have. How much liquid equivalent is going to fall is something we struggle with year-round."
The winter issue is what form the liquid will take: rain, freezing rain, snow or sleet.
"The problem is, our observations and our models aren't accurate enough to give us that ironclad distinction between one or the other," Bradshaw said. "We continue to have a heck of a time nailing those. Is it going to be sleet or freezing rain?"
Ultimately, it was sleet, not freezing rain. And that quickly overwhelmed local and state road crews.
"Sleet makes a deeper accumulation than freezing rain. That really compounded the problem for road crews who thought we were going to get a half-inch of ice, but we had as much as 4 inches of sleet," Bradshaw said.
"When that compacts, that stuff, especially combined with freezing rain, is extremely difficult to remove," he said. "Once you drive on it, it just polishes down to a layer that grabs onto asphalt. It's tough to crack off."
Graders, not plows

But two things were tricky. For starters, the storm stretched from
Also, the precipitation was falling as sleet, which is dense and sticks to roads like glue, so it typically can't be removed solely with snowplows. Instead, the agency put into service as many road graders as it could get its hands on.
The graders must make multiple passes on a sleet-covered bridge because sleet is far denser than fluffy snow.
As the ice melted and refroze, potholes formed within the thick layers of ice -- creating an extraordinarily rocky driving condition that became widely known as " cobblestone ice."

What did we learn?
There's always room for improvement.
Officials from various agencies that responded to the storm will debrief one another and will probably learn how to handle weather emergencies better in the future, said
Heck, they might get another crack at it sooner rather than later. Winter officially arrives this week, and the
And there may be an economic justification for the state to devote more resources to opening roads as quickly as possible after an ice storm.
Businesses that deal in perishable products or just-in-time inventory simply can't get their goods to market when their trucks are parked alongside ice-covered highways for days.
Also, residents with hourly jobs may lose wages because they can't get to work -- dollars that may never be made up.
"Nobody was starving, but the whole cycle of transportation was goofed up, and it will probably take a week for it to get back up," said
For transportation planners, the weather service has to do a better job communicating with its emergency partners, Bradshaw said.
"We need to give them some better alternate scenarios," he said. "The challenge for them, if I tell them there's a 25 percent chance of sleet, they have to decide the cost benefit" of bringing in equipment for an event that might not happen.
The alternative is to save the money and deal with the public relations consequences if weather shuts down the region.
"People want to hear a 'yes' or 'no,' " Bradshaw said. "The weather just confounds that. It doesn't fall into a neat category."
