A cold outbreak hitching with a pair of Mediterranean storms will spread a streak of snow over central and eastern Europe late this week into early next week.
These same storms will also bring the threat of excessive rainfall and flooding from Italy to the western Balkan Peninsula.
Between Friday and Sunday, travel over hilltop and mountain roadways of central Europe may be disrupted temporarily from the Alps east to the Carpathians.
Farther east, heavy, wet snowfall, potentially 6 to 12 inches, could prove disruptive in a swath from northwestern Ukraine and southern Belarus into central Russia, including Moscow.
A few of the central Europe cities likely to get at least a little snow will be Munich, Salzburg, Vienna, Ljubljana and Budapest.
In the east, the snow streak will likely reach from Lviv, Ukraine, to Moscow and Nizhniy Novgorod.
The late-week storminess will follow earlier outbreaks of snow, coinciding with the onrush of cold air, from Scandinavia and Finland to northwestern Russia and the Baltic states.
A foot of new snow blanketed Nikel, Russia, as of Thursday.
Travelers to the region may need to pack some cold-weather clothes.

Warmth will wax June-like in some capitals. Many others will experience the feel of mid summer for at least one day.
The Huntsville Mayor, Claude Doughty, said that it would take months and millions of dollars to repair road damage.
Localized severe wind gusts near 60 mph (about 95 km/h) will whip Ireland, Wales, northern England and southern Scotland.
