Earth Changes
Temperatures on Sunday and Monday at the tip of the Sunshine State are expected to be in the low-to-mid-40s.
The fast-moving cold that gave Florida the chills had combined with moisture from the Gulf of Mexico to dump a dangerous mix of ice and snow throughout the Southeast, coating roadways with a slick glaze.
Numerous school systems throughout the region shut down.
At least nine deaths around the country have been blamed on the round of winter weather this week.
Whatever happened to global warming?
Such weather doesn't seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn't disprove global warming at all, it's just a blip in the long-term heating trend.
"It's part of natural variability," said Gerald Meehl, a senior scientist at the National Center for Atmospheric Research in Boulder, Colo. With global warming, he said, "we'll still have record cold temperatures. We'll just have fewer of them."

Vehicles travel in white out conditions caused by blowing snow on Interstate 80 west of Omaha, Neb.
The tractor-trailer jackknifed on Interstate 70, crossed the highway median and swerved into oncoming traffic, colliding with a small bus transporting adult disabled passengers, the Ohio Highway Patrol said.
The driver of the 17-passenger bus was among those killed, said Sgt. Raymond Durant. One person was in critical condition and six others were injured and taken to hospitals, he said. Six of the injured were on the bus, and the tractor-trailer driver was also injured.
Durant said the bus was carrying 11 people at the time of the crash.
Methane is about 20 times more potent than CO2 in trapping solar heat.
The findings come from measurements of carbon fluxes around the north of Russia, led by Igor Semiletov from the University of Alaska at Fairbanks.
With millions of Britons battling through snow and ice to get to work today, scientists claim that the cold conditions should not be used as evidence against man-made climate change.
Blizzards, ice and sub-zero temperatures that have gripped the UK for almost a month in a record deep freeze are not "robust" indicators of global weather patterns, they say.

Dead octopuses have been washing up on shore in Vila Nova de Gaia, Portugal
Twelve hundred pounds is a lot of dead cephalopod, especially when no one seems to know for sure what killed them. Local biologists have ruled out pollution or contamination because no other species were affected. And although some suggest that perhaps a boat, illegally fishing the multilegged creatures, threw them overboard in a panicked attempt to avoid detection, that possibility also seems unlikely. "The sea has been very rough," says Oliveira. "No one has been out fishing for days."
A week before Christmas, Magnus Bladh of the Ottenby bird station, located on Öland's southern cape, was strolling along the beach with a colleague when he saw something he'd never seen before.
"Temperatures were below freezing and there was a light wind, but it was very cold! In the seaweed we noticed at least 200 large ice balls," he said in a report to Swedish meteorological agency SMHI.
"The balls varied in size but the biggest ones were quite large, some larger than a football."
From head to toe there is barely a patch of land not blanketed by the heaviest snowfall in 50 years.
It was taken at 11.15am on Thursday by the NASA satellite Terra and transmitted to the University of Dundee Satellite Receiving Station.
The image gives an impression of just how deep with snow has been across most parts, including the southern belt of England: parts of Hampshire received more than 16 inches in just a few hours earlier this week.
Only the western coastal extremes, such as Dorset's Isle of Purbeck in the south and more surprisingly Jura and Islay in the Inner Hebrides, have escaped widespread coverage.
The picture also demonstrates how little thawing has taken place, as most of the snow lying across lowland parts fell on Tuesday and Wednesday.
Up to 5cm of snow fell in Dublin yesterday and, at one point, the capital was hit with a thunder storm.
Met Eireann issued a severe weather warning last night after temperatures were forecast to fall to as low as -8C.
Forecaster Vincent O'Shea said driving conditions would become even more hazardous over the coming days, with no respite in the freezing temperatures expected.
Factories in the north-west of England and east Midlands are today having their energy supplies cut off for the first time in years as the severe weather and creaking power infrastructure lead to 1970s-style rationing.
In the first tangible sign that fears over energy shortages are translating into supply disruption, the National Grid has withdrawn gas via suppliers such as British Gas from 94 industrial customers who have signed up to interruptible contracts in a bid to safeguard power to domestic homes.
The Grid, which operates the UK transmission networks for both electricity and gas, told guardian.co.uk that the gas transmission network in certain parts of the country was operating at 96% capacity and it was not possible to go beyond this.
