This year temperatures in Tajikistan reached an UNUSUAL minus-17 degrees Celsius, the lowest since 2002. The lowest temperature is usually between minus-five degrees to minus-seven degrees Celsius. Geologists say such cold weather is the result of global climate changes. UNUSUAL prolonged frost has also compounded the situation. The situation in many settlements and towns across Tajikistan is acute, with no gas or electricity.
WISCONSIN -USA, According to a professor of atmospheric and oceanic sciences, the snow was UNUSUAL throughout the weekend in both its type and accumulation. “This is wildly out of the ordinary. We don’t get storms like this very often.” Nearly 18 inches fell from Friday evening to Sunday morning. With temperatures hovering around 32 degrees, the snow was an uncharacteristically wet mix when it arrived in the city. “That’s not common around here. Usually that’s the type that shows up in New England, with that concrete, mashed potato type of snow.” The irregular weather developed Friday from an upper-level disturbance over California. This past weekend's storm SET A RECORD for the first time more than four inches of snowfall has been recorded on three consecutive days - the historical records date back to 1869. The National Weather Service reports six inches of snowfall for Madison on Friday, 4.4 inches for Saturday and another 4.9 inches on Sunday, for a weekend total of 15.3 inches. The high moisture content of this weekend's heavy snows has slowed snow plowing and removal efforts - almost doubling the usual time it takes to clear the city's streets. This is the fourth snowiest February on record, and with meteorologists forecasting another inch or two between now and March 1, third or even second snowiest may yet be within reach.

PENNSYLVANIA - USA, The sleet that fell on Feb. 13 and 14 was a wild and extraordinary event. It was ONE OF THE MOST DISRUPTIVE NORTHEAST STORMS ON RECORD. People wound up stranded on I-78 for up to 24 hours. Atop an unexpectedly stubborn layer of cold air, the Valentine's Day storm created a strange and persistent atmospheric parfait. Warm air melted snow on the way down, but then cold air refroze it before it landed. What resulted was prodigious, perhaps RECORD, amounts of sleet. The models were calling for a major ice storm - with a "bull's-eye" of up to 2.5 inches of precipitation in northeastern Pennsylvania. That's the water equivalent of up to three feet of snow. The best estimate is that 4 of the 7 snow and ice inches measured at the Allentown station consisted of sleet. That is a phenomenal amount. Typically, it takes a forecast of a mere half-inch to trigger a "heavy sleet warning." So 4 inches would be eight times the warning criterion. Sustained sleet is at the very least UNUSUAL. Sleet suggests an atmosphere in transition. Ordinarily it occurs when warm air aloft is entering or exiting, as rain is changing to snow or vice versa. Rarely is it a main event.
