This weekend will bring warm front to Europe on Friday and the temperatures will rise of 5°C till 10°C. The front will bring snow, which on most places will melt.
After the warm weekend, a big cyclone above the Baltic sea will bring a cold air from North to Europe, so there will be in some place bigger drop in temperature than the former rise. Again temperature below zero and snow are expected.
Be careful! In the video, the blue lines are isotherms (lines connecting places with the same temperature) and not isobars!
