Earth Changes
Lancaster County is getting own March Madness today, courtesy of Mother Nature.
The county awoke to rain, which turned to slushy sleet, which turned to snow, which was supposed to accumulate 4 to 8 inches by midnight in most areas of the county.
Northern and higher areas of the county could get more snow, maybe close to a foot, said Eric Horst, Millersville University meteorologist.
This late-season snow surge comes, of course, on the heels of near 80-degree weather earlier this week, and ahead of 60-ish weather that's supposed to return next week.
"Whatever snow we get, most of it is gone after the weekend," Horst said. "That's a hallmark of spring storms. It doesn't last."

A catastrophic collapse of the Arctic sea ice could lead to radical climate changes in the northern hemisphere according to scientists who warn that the rapid melting is at a "tipping point" beyond which it may not recover.
The scientists attribute the loss of some 38,000 square miles of sea ice - an area the size of Alaska - to rising levels of carbon dioxide in the atmosphere as well as to natural variability in Arctic ice.
The December 2006-February 2007 U.S. winter season had an overall temperature that was near average, according to scientists at the NOAA National Climatic Data Center in Asheville, N.C. Precipitation was above average in much of the center of the nation, while large sections of the East, Southeast and West were drier than average. The global average temperature was the warmest on record for the December-February period.
U.S. Temperature Highlights
The winter temperature for the contiguous United States (based on preliminary data) was 33.6 degrees F (0.9 degrees C). The 20th century average is 33.0 degrees F (0.6 degrees C). Statewide temperatures were warmer than average from Florida to Maine and from Michigan to Montana. Cooler-than-average temperatures occurred in the southern Plains and areas of the Southwest.
The 11th warmest December on record occurred in 2006.

Geophysicists in Australia think they may have solved the long-standing enigma of how the Andes mountain range was formed. Using computer simulations that model the fluid dynamics and mechanics of tectonic plates, they reckon that the Andes were formed when one tectonic plate in the Pacific slides or "subducts" under a neighbouring plate beneath South America in an uneven fashion. The existence of the Andes has baffled researchers because most other large mountain ranges, such as the Himalayas, have emerged where two plates collide head-on.
All tectonic activity on Earth is driven by subduction zones, where one plate is sucked underneath another into the Earth's mantle. Now, for the first time, a team led by Wouter Schellart at the Australian National University in Canberra has created the first genuine 3D model of how plates move at subduction zones over time.
WILKES-BARRE - A one-two punch by Mother Nature will bring moderate flooding along lowlands of the Susquehanna River on Friday and anywhere from six to 12 inches of snow by Saturday afternoon.
Light snow began falling in the Wyoming Valley just before 7:30 a.m. and is expected to increase in intensity throughout the day.

Winter is going out with a mid-March roar.
After a few days spring temperatures, the city awoke Friday to a wintry mess of snow, icy roads, treacherous commutes and a winter storm warning with forecasts of an angry Nor'easter on the way.
Fears of severe flooding in Vermont have finally ebbed, but the National Weather Service in Burlington has posted the latest weather concern - another significant snow storm.
A storm warning has been issued for much of the state, beginning tonight at 6 p.m and extending through 8 p.m. on Saturday. A heavy snow warning was issued for the southern part of Vermont, just south of Rutland.
ANCHORAGE -- Perhaps instead of "Big Wild Life," Anchorage should consider the motto "Really Really Cold." The city has seen unseasonably frosty temperatures for an unusually long period, according to the National Weather Service.

The December 2006-February 2007 winter season temperature was marked by periods of unusually warm and cold conditions in the U.S., but the overall seasonal temperature was near average, according to scientists at NOAA's National Climatic Data Center in Asheville, N.C. Precipitation was above average in much of the center of the nation while large parts of the East, Southeast, and Southwest were drier than average. The global temperature was the warmest on record for the December-February three-month period.

WASHINGTON -- This winter was the warmest on record worldwide, the government said Thursday in the latest worrisome report focusing on changing climate.
The report comes just over a month after the Intergovernmental Panel on Climate Change said global warming is very likely caused by human actions and is so severe it will continue for centuries.
