(cnn news las vegas) - No matter how you spell it, ice is a four-letter word Friday. Just ask folks living anywhere from Texas to Tennessee.
Across this swath of America, birthday plans have been canceled, long-awaited reunions have been put on hold, and weekend plans have become uncertain.
To put some perspective on the scope of the storm, consider that Hot Springs, Arkansas, experienced a record high of 75 on Wednesday. By Friday morning, the city was in the middle of an ice storm.
On Friday, it was colder in Dallas (26 degrees) than in Anchorage, Alaska (34 degrees), prompting the cancellation of the Dallas Marathon and spurring Dallas/Fort Worth International Airport to cancel almost 700 flights, about 80% of those scheduled.
Those areas are in the bull's-eye of a treacherous ice storm, threatening to coat everything in its path with up to an inch of frozen water.
Ice is slippery but also heavy. It tends to bring down tree limbs and power lines when accumulations get thick.
Storm deaths
In some cases, the weather has been deadly. At least four deaths have been attributed to the storm.
In Texas, a passenger in a car was killed Thursday in Hockley County when the vehicle lost control and crashed into another car, Sgt. Bryan Witt of the Texas Department of Public Safety said.
An Arkansas man was killed late Thursday when a tree fell on his camper in Pope County, Tommy Jackson, an Arkansas Department of Emergency Management spokesman, said Friday. Jackson said the death was related to the weather but couldn't provide details about the weather at the time. Rain and freezing rain were reported in the area Thursday night.
Highway Patrol officials in Oklahoma blamed two deaths on the weather - a 24-year-old man in Owasso and another unidentified person in Muskogee - but did not release details of those incidents.
Officers have responded to 106 weather-related crashes since Thursday morning.
About 116 storm-related injuries have been reported in Oklahoma, including 48 falls, the state health department said.
The storm struck fear in residents.
In Dallas, iReporter Earl Wallace IV said he was on the front porch of his home Friday morning when he heard a loud crack and a rush of wind. A large tree had fallen on two nearby homes.
"One of the homeowners emerged crying and talking on the phone," said the 32-year-old creative director. "The tree had crashed down into her dining room. I felt nervous, shocked and scared for the families inside."
Two homes were damaged - one with a giant hole in the roof - but no one was injured.
Getting ready
In Tennessee, Memphis Light, Gas and Water has 426,000 customers and is preparing for the worst. As of early Friday afternoon, about 5,000 customers were without power.
"MLGW employees have been monitoring this winter storm situation, and we have all of our resources in place should the winter weather hit Memphis and Shelby County," said Jerry Collins Jr., the company's president and CEO. "If indeed a significant storm blankets our city, we are ready to respond."
The ice also makes travel messy - real messy.
Road crews in Memphis are ready to throw down 4,000 tons of sand to give drivers traction, CNN affiliate WMC reported.
The governors of Tennessee and Arkansas declared states of emergency ahead of the worst of the storm.
"The most unsettling aspect about Arkansas' weather for most of us is its looming uncertainty," Gov. Mike Beebe said.
"During severe weather season, we know when conditions are ripe for tornadoes but never exactly where and when they could strike. In winter, that uncertainty takes a different form but can still create widespread anxiety," he said.
"Often, only a few degrees above or below the freezing mark can make the difference between a cold rain, a blanket of snow, an ice storm or a mixture of all of the above."
In the Dallas-Fort Worth area, roads were passable overnight, but it was a fine line as temperatures slipped below freezing. The slushy mess slowly turned into crunchy, bumpy ice.
Police urged caution for anyone on the road and reported 21 major car accidents and 32 minor ones Friday.
According to energy provider Oncor, more than 200,000 customers were without power in the Dallas-Fort Worth metro area as of Friday morning. This is the largest concentration of outages, with scattered outages elsewhere in the state.
Nearly 30,000 were without power in Arkansas, energy companies reported.
A dark cloud over Dallas events
The National Weather Service predicts a wintry mix of precipitation through Sunday.
That forecast prompted the cancellation of a downtown Dallas holiday parade scheduled for Saturday for the first time in 26 years. The city also called off its annual marathon slated for Sunday and the accompanying Health & Fitness Expo scheduled for Friday and Saturday.
"We regret that the race will not go on as planned, but are confident this decision is in the best interest of our runners, volunteers, spectators and the general public," A Dallas Marathon statement said.
While the focus Friday was on the ice storm stretching from Dallas to Memphis, Mother Nature looked ready to throw another punch.
A wintry mix was forecast for Washington beginning about noon Sunday. The National Weather Service said it has the potential to be an ice storm from late Sunday afternoon through the evening hours, but temperatures are expected to rise above freezing by rush hour Monday.
A new storm entered the West, bringing snow to the Pacific Coast on Friday. The storm brought significant snowfall to Portland, Oregon, and there is a chance for rare snow in Las Vegas on Saturday. This storm will bring another round of wintry weather to the East by late in the weekend.
Little competition for cameras in its price range

Image: The new battery, which is backwards compatible with the D5200, offers a longer life. There is no low-pass filter on the sensor, for extra resolution 
In addition to the D5300, Nikon has also announced a new pro-level prime lens, the AF-S Nikkor 58mm f/1.4G. Carrying the legacy of popular Noct Nikkor 58mm f/1.2 lens, this fixed 58mm focal length (35mm/FX equivalent; 87mm DX/cropped format) is ideal for shooting portraits, landscapes, and street photography, Nikon says, but it's all about achieving bokeh - that artistic background blurring - with the nine-blade diaphragm. Made for low-light capture, the lens has Nikon's Nano Crystal coating to avoid ghosting and flare. The Silent Wave Motor operates quietly when autofocusing, which is key for recording video.
