Snow expected from Mississippi to Maine; Florida inspects storm damage

(CNN) -- A quick-hitting storm is expected to coat most of the Northeast and parts of the South with snow Wednesday, forecasters said.

In Florida, the National Weather Service has dispatched survey teams to investigate damage caused by storms that moved across the state Tuesday evening. They found that a tornado near Boca Raton had snapped and uprooted trees, CNN meteorologist Sean Morris said.

A tornado near Alva, Florida, destroyed and damaged six mobile homes, and straight-line winds between 60 and 90 mph damaged several homes near Groveland, Florida, Morris said.

In St. Petersburg, Florida, 90 mph straight-line winds damaged a gas station and injured one person, Morris said.

The National Weather Service issued winter storm warnings and advisories that stretched from Maine to northern Mississippi. Continue ►

Yes, again -- forecast calls for up to a foot of snow

Light snow dusted much of the region today, a prelude to a bigger storm arriving Wednesday, a nor'easter that, according to forecasters, could dump 8 to 12 inches of snow on some areas of Massachusetts.

The National Weather Service warned that the coastal storm could drop more than 6 inches of snow in Western, Central, and Northeastern Massachusetts, including Boston; drop 4 to 8 inches on the Cape and islands; and drop 8 to 12 inches on Southeastern Massachusetts.

The snow is expected to begin late afternoon or early evening. On the Cape and islands, it's expected to begin as rain, then change to snow by late Wednesday night.

Forecasters warned of slippery roads on Wednesday night. In Southeastern Massachusetts and on the Cape and islands, they said, the heavy wet snow may bring down tree limbs and power lines.

The unpleasant weather news comes as the state is emerging from a bitter cold snap -- the temperature, which had dipped to 2 below zero on Sunday night, rose to 30 by midafternoon at Logan International Airport -- and with the state already far ahead of the average in terms of snowfall for the year.

Meanwhile, Accuweather.com, the private forecasting service said today that persistent cold is expected through at least the middle of February across much of the eastern part of the country. The colder-than-normal weather could break in late February, but cold and storms could return from mid- to late March into April, the service said.

The New York Times reports today that the cold weather has been caused by the weakening of a pattern of atmospheric circulation that normally keeps cold air penned farther north. The weakening has allowed tongues of cold air to move south, while warm air moves north. Continue ►

Is the Surging Yellowstone Caldera -the World's Largest Supervolcano- Poised to Erupt?

With some 80% of airports in Europe shut down last summer due to the lingering ash cloud created by Iceland’s Eyjafjallajökull volcano, we thought it would pay to take an updated look at the possibility of the world's most massive volcano -the Yellowstone Plateau- erupting and the potential consequences. Recent earthquakes on the west side of Yellowstone caldera were part of the intense January/February 2010 earthquake swarm of ~2,350 earthquakes.



Yellowstone National Park's caldera, which covers a 25- by 37-mile (40- by 60-kilometer) swath of Wyoming, is an ancient crater formed after the last big blast, some 640,000 years ago. The simmering volcano has produced major eruptions—each a thousand times more powerful than Mount St. Helens's 1980 eruption—three times in the past 2.1 million years. The supervolcano has recently caused miles of ground to rise dramatically, scientists report beginning in 2004, which saw the ground above the caldera rise upward at rates as high as 2.8 inches (7 centimeters) a year.Is it poised for yet a fourth major explosion?

Some 600,000 years ago there was a colossal cauldron of magma, a supervolcano, that exploded with such violence that it left an ash layer almost ten feet deep a thousand miles away in eastern Nebraska killing all plant life and covering almost all of the United States west of the Mississippi. Modern geological surveys have shown that this supervolcano erupts catastrophically every 600,000 years, and the land that supervolcano is trapped in was called by Blackfoot Indians 'the land of evil spirits' -what we call today, Yellowstone National Park.

A report from scientists at the University of Utah shows that the “supervolcano” underneath Yellowstone has risen at a record rate since mid 2004. Apparently, a “pancake-shaped blob” of molten rock he size of Los Angeles was pressed in to the slumbering volcano, some six miles down.

“There is no evidence of an imminent volcanic eruption or hydrothermal explosion. That’s the bottom line,” says seismologist Robert B. Smith, lead author of the study and professor of geophysics at the University of Utah. “A lot of calderas [giant volcanic craters] worldwide go up and down over decades without erupting.”

The journal Science however reported that the caldera floor of the massive volcano has risen 3 inches, per year, for the past three years. This is a rate of growth three times more rapid than ever observed, since records were first kept back in 1923.




“Our best evidence is that the crustal magma chamber is filling with molten rock,” Smith says. “But we have no idea how long this process goes on before there either is an eruption or the inflow of molten rock stops and the caldera deflates again,” he adds. Continue ►

A Total Eclipse at the End of the World

Explanation: Would you go to the end of the world to see a total eclipse of the Sun? If you did, would you be surprised to find someone else there already? In 2003, the Sun, the Moon, Antarctica, and two photographers all lined up in Antarctica during an unusual total solar eclipse. Even given the extreme location, a group of enthusiastic eclipse chasers ventured near the bottom of the world to experience the surreal momentary disappearance of the Sun behind the Moon.

One of the treasures collected was the above picture -- a composite of four separate images digitally combined to realistically simulate how the adaptive human eye saw the eclipse. As the image was taken, both the Moon and the Sun peaked together over an Antarctic ridge. In the sudden darkness, the magnificent corona of the Sun became visible around the Moon. Quite by accident, another photographer was caught in one of the images checking his video camera. Visible to his left are an equipment bag and a collapsible chair. Continue ►

Snow-covered Mass. lifts state of emergency

(Reuters) - Massachusetts lifted its state of emergency on Thursday as New England dug out from under deep snow following a winter storm that blasted the region with high winds and chilly temperatures.

The storm blanketed eastern New York and western New England with anywhere from 8 inches to unofficial reports of 38 inches of snow in Berkshire County in Massachusetts, said meteorologist Brian Frugis with the National Weather Service in Albany, New York.

Despite the snow from Wednesday's storm, Massachusetts emergency management teams and state police reported no major accidents.

"The road clean-up was excellent," said Peter Judge, spokesman for the Massachusetts Emergency Management Agency. "We attribute that to the fact that folks stayed off the roads yesterday."

Massachusetts lifted the state of emergency it had declared at noon on Wednesday, at the height of the storm. Such declarations are typically made in order to gain access to emergency funding and to mobilize certain resources, such as the National Guard, to cope with the storm's impact.

Power outages that affected more than 100,000 homes at the peak of the storm were reduced to just 3,500, said Judge.

Traffic patterns at Boston's Logan International Airport also were returning to normal.

Two active runways were available at Logan, with airlines operating at about 90 percent of a typical schedule, said Logan spokesman Phil Orlandella.

Winds that were a major factor in Wednesday's storm were likely to linger in the 10 to 25 mph range, which may cause snow to blow and drift, say meteorologists.

The winds were creating a significant chill in the air throughout the Northeast that was likely to keep the snow from melting, according to Accuweather.com meteorologists.

Wednesday's blizzard-like conditions did set some records, including a new snowstorm record in Hartford, Connecticut of 24 inches and a new snowiest day in Worcester, Massachusetts with 21.1 inches, according to The Weather Channel.

The heavy snow did not cause major outages or accidents in Vermont, said Mark Bosma, spokesman for Vermont Emergency Management.

In fact, Bosma said the state's ski industry "is doing backflips right now" over the fresh snow ahead of the three-day holiday weekend.

The latest storm to batter the Northeast came on the heels of separate weather systems that wreaked havoc across the South and Midwest.

"The potency of Wednesday's snowstorm came to be after two separate storm systems merged together," said Accuweather.com senior meteorologist Kristina Pydynowski. Continue ►
