(CNN) -- Another band of frigid weather will blanket the eastern two-thirds of the nation Wednesday, battering states already dealing with record-low temperatures that have been blamed for at least five deaths.



The system will bring blistering cold weather and winds across the country, including many states not used to such temperatures.



In Florida, Gov. Charlie Crist declared a state of emergency because of the threat to the state's lucrative crop industry. His order aims to help farmers across the state salvage what they can by lifting weight limits on trucks and allowing them to get already harvested crops out of the cold.



In other areas of the country, low temperature records are being broken and are likely to continue to fall.



Later this week, the temperature could drop below zero for the first time in St. Louis, Missouri, since 1999, according to the National Weather Center.



Little Rock, Arkansas, could see an actual temperature of 10 degrees and wind chill of 20 below zero on Friday morning, according to the National Weather Service.



The high temperature will be in the 20s on Thursday and Friday in Dallas, Texas, where consecutive days that cold have not happened since 1998, the weather service said.



The northern Plains could see wind chills of 20 to 30 below zero through Wednesday, CNN meteorologist Chad Myers said.



"Some locations could see temperatures 30 to 40 degrees below normal" on Thursday across parts of the Plains, upper Midwest and Ohio River Valley, CNN meteorologist Sean Morris said. By Friday morning, afternoon highs will struggle to make it above zero, he said.



"What's unusual about this is the length of the cold snap," CNN meteorologist Rob Marciano said.



"Typically across the South, you'll get a two- to three-day cold snap, and then temperatures will moderate," he said. "But we're getting reinforcing shot after reinforcing shot, and that pattern doesn't look like it wants to break down until at least next week."



Some states were still dealing with the aftermath of the first cold snap. In Atlantic, Iowa, a record set in 1958 was broken when the temperature dropped to minus 29 degrees Monday, according to the National Weather Service.

A homeless man was found frozen to death in Kansas City, Missouri, where the temperature was 1 degree Tuesday morning, and Salvation Army officials said they desperately need donations of hats, gloves and socks, CNN affiliate KCTV reported.



The temperature is not expected to rise above zero in Kansas City on Friday.



A winter storm watch is in effect for Kansas City, where 2 to 4 inches of snow and near-blizzard conditions will be possible on Wednesday afternoon, CNN meteorologist Sean Morris said. A winter storm watch has also been issued for Memphis, Tennessee, where 2 to 4 inches of snow will be possible from late Wednesday evening into Thursday morning.



The northern Plains could see wind chills of 20 to 30 below zero through Wednesday, Myers said.



"Some locations could see temperatures 30 to 40 degrees below normal" on Thursday across parts of the Plains, upper Midwest and Ohio River Valley, Morris said.



A winter storm warning for moderate to heavy snowfall was in effect into Tuesday afternoon in parts of northwestern Washington state, northern Idaho, Montana and northern Wyoming, the weather service said.



Moderate to heavy snowfall also is possible in much of North Dakota from Tuesday to Wednesday, the weather service said.



A dusting of snow will be possible in Atlanta, Georgia, on Thursday, Morris said.



At least four cold-related deaths have occurred in Tennessee. One was an 81-year-old Alzheimer's patient who apparently wandered outside during the night wearing nothing but a bathrobe, police said. John Anderson's body was found in his driveway Monday morning.
