Whatever charm winter weather may have held with North Texans, much of it has melted away with the last standing neighborhood snowman.

For weather forecasters, street crews and other workers who have tried to keep roads safe, homes heated and people informed, the crummy weather has meant long hours and extra shifts.

“I’m tired of it,” said Dale Long a spokesman for the city of Dallas. “Over the weekend our emergency operations center was open 24 hours. I worked two overnight 12-hour shifts and I can’t sleep during the day. I’m still trying to get caught up.”

Road crews have been busy sanding streets and sanding them again. Other city departments such as police, fire and environmental health have also been clocking extra hours. And with more bad weather in the forecast, it could be another long sleepless weekend.

“We have to do what we have to do,” Mr. Long said. “The city of Dallas doesn’t shut down. We want everyone to be safe.”

At the National Weather Service in Fort Worth, meteorologists have been working extra hours to prepare forecasts and warn North Texans about impending storms and icy conditions.

“Over the weekend they brought in extra people but that’s not uncommon during any sort of weather event,” meteorologist Jessica Schultze said.

The Fort Worth office has 15 meteorologists who handle forecasts for 46 counties across north Texas and into portions of central Texas.

At the Texas Department of Transportation, crews were growing weary of 12-hour shifts.

“We’ve been working 12-hour shifts for five days,” spokeswoman Kelli Petras said. “Then we had one day where we went home to sleep and we got called in at 5 a.m. We are all tired and want this storm to be over.”

Despite the long days and nights, employees were in good spirits because they know their jobs of making streets safe is important, Ms. Petras said.

“We realize a little bit of sacrifice on our part helps out greatly and that give us a little pride,” she said.

Bill Shannon and other staffers at the Dallas/Fort Worth International Airport prepared to work more long hours this weekend as the region braced for more dicey weather.

A duty manager at the Airport Operations Center, Mr. Shannon said his staff had been working 12-hour shifts during the recent storms, assisting airlines with de-icing efforts and monitoring weather conditions. Mr. Shannon had worked four such shifts since Saturday. A couple of staffers even slept at the airport, he said.

“It is tiring,” he admitted. “But as long you can get your sleep and food, you’re okay.”
