( CNN ) -- Much of the country has turned up the heat during the deep freeze this week , but for some , the icy chill is on its way out . The Deep South joined most of the rest of the nation with sub-zero temperatures Friday as a fast-moving cold front knifed its way down to Florida . Combined with moisture from the Gulf of Mexico , the frigid air dumped a dangerous mix of ice and snow throughout the Southeast Thursday night and Friday morning , coating roadways with a slick glaze . At least nine deaths around the country were blamed on this week 's round of winter weather . Relief is in sight for the Midwest this weekend , however , as higher temperatures make their way eastward , according to CNN meteorologist Chad Meyers . But the cold will tighten its grip before warmer air takes hold . An Arctic air mass over the Plains will cause severe wind chills through Saturday morning , the National Weather Service reported . The weather service has issued wind chill advisories for northwestern Missouri , northeastern Kansas , eastern Nebraska and southwestern Iowa , meaning the wind chill could be severe enough to cause frost bite or hypothermia . The South will also experience higher temperatures by the end of the weekend but that region , too , will shiver a while longer . Floridians braced for a second surge of Arctic air that promised to dip well into the southern parts of the state . Key West already set a record low temperature on Thursday , bottoming out at 47 degrees -- shattering the previous low set back in 1897 . Temperatures on Sunday and Monday are expected to be in the low-to-mid-40s . The citrus growing regions in Florida and Texas will have to keep an eye on their crops as the cold air remains in the area , Meyers said . In southern Texas , the National Weather Service has issued a hard freeze warning through late Saturday morning , saying that the conditions `` will kill temperature-sensitive vegetation and could cause widespread damage or destruction to crops . '' The East might not feel the warmth until Tuesday , Meyers said , and will continue to feel temperatures that are 10 to 20 degrees below average . Residents in New York City and the surrounding area , including northeastern New Jersey and southern Connecticut , wo n't feel temperatures above 30 degrees this weekend , the weather service reported . Saturday night is expected to be the coldest , with lows in the teens and below in some areas , the weather service said . iReport : Show CNN how how the cold is affecting you . While forecasts do n't predict snow east of the Rocky Mountains in the coming days , Meyers said , a storm system in the far west could drop as much as 10 feet over the Canadian site of the 2010 Winter Olympics . Flakes are expected Saturday and may fall in the coming days on a swath of land ranging from British Columbia to the northern Sierras of California , Meyers said . The most snow -- about 10 feet -- is expected to fall in Canada 's Whistler Blackcomb , the venue for the Olympic Alpine skiing event . The heavy snow is a plus for the event but could also bring threats of avalanches , Meyers said . 29-car pileup near Atlanta airport . Vancouver , British Columbia , hosts the 2010 Games , which begin with the opening ceremony on February 12 . Alpine skiing begins the following day .
