An extreme early spring storm will spread a potentially crippling blanket of snow over eastern Europe to western Russia.
Snowfall of 1, 2 and even 3 feet will impede, if not immobilize, travel over parts of Ukraine, Poland, Belarus and western Russia. Strong winds and drifting will magnify the difficulty for residents.
The snowstorm will get underway Friday in western Ukraine, southeastern Poland and southern Belarus, continuing Saturday. Meanwhile, snow will spread across northern Ukraine and into western Russia, where heavy snowfall will last until Sunday.
Some cities along the forecast path of heavy snow are Lviv, Ivano-Frankivsk and Kiev in the Ukraine, Homyel in Belarus and Bryansk and Orel in Russia.
Moscow, still mantled beneath 2 feet of snow as of the first day of spring, is expected get the northern edge of the storm Sunday into Monday, when about 6 inches of snow could fall.
Snow is forecast to stay south of the Belarus capital, Minsk.
What is to trigger the massive falls of snow is low pressure, fairly innocuous as it crossed Italy on Wednesday. However, this low will wrap up a strong late-winter storm as it reorganizes east of the Transylvania Alps early Friday.
The winter of 2012-2013 has been outstanding for snowfall over parts of central and eastern Europe, including land in the direct path of the coming blizzard. Winter snowfall is thought by AccuWeather.com meteorologists to have reached about 200 percent of normal in areas from Kiev to Moscow, for instance. Last week, a blizzard unleashed heavy windswept snowfall from Hungary and northwest Ukraine, Belarus and central Russia, including Moscow and Minsk.

The plum rains are known as "meiyu" in China, the "baiyu" or "tsuyu" in Japan, and the "jangma" in the Koreas. The heart of the plum rain season stretches from early June to mid-July, with a tendency to shift south to north across the affected area.
In the wake of the mid-June cloudbursts, most of Pakistan to northwestern India last week saw a return to dry, hot weather typical of the weeks leading up to the Monsoon onset. It was as if the Monsoon withdrew to its "normal" position for the latter half of June.
The 38.5 degree C (101 degrees F) reading Tuesday in Ajaccio, Corsica, may have been tops in Europe.
Monsoon Onset was June 13th, 2013, in Delhi, almost two weeks earlier than average. The June 15th onset at Karachi and Islamabad was more like three week ahead of schedule.
In Pakistan, hit-or-miss downpours missed the Sindh capital, Karachi. One did hit Pad Idan, where it left 60 mm of rain Wednesday. This was more than 20 times greater than the normal June rainfall.
It is still possible that this scenario is over wrought as to the intensity and spread of rain in Pakistan and northwestern India. However, it is the hunch of the present forecaster that some very unusual weather is going to unfold in the Subcontinent during the next week!
