After a major winter storm brought feet of snow to the Olympic venues a week ago, milder weather returned earlier this week. Since then, chillier conditions have filtered back into the region with snow in the higher elevations to close the week.
Colder air began to arrive on Wednesday night causing rain to change to snow in the higher elevations while rain continued to fall in Sochi and the Olympic Village.
Snow is expected to continue through Friday night at varying intensity across the mountains giving the resorts a boost in snow conditions. In Krasnaya Polyana, located at the base of the mountain venues, 5 cm (2 inches) of snow fell Thursday into Friday with higher amounts in the mountains where many of the skiing and sliding sports will take place.

In Sochi, a cold rain fell through Friday morning before ending.
A weak storm system will bring more rain to Sochi early next week while some snow is again expected for the skiing areas.
The weather leading up the Olympics is expected to turn milder which could lead to deteriorating conditions on the slopes used for the Olympic Games.
Whether or not the weather pattern will lead to problems for the Olympics will depend on how mild and how long this pattern lasts, but the concern exists nonetheless. A prolonged stretch of cold weather leading up to the Games is not expected.
