Winter weather conditions will continue on. On Thursday night, a flush of icy cold continental air will reach us. This temperature decrease will prevail past the weekend. A strong, easterly wind will get up in the mountains and intensify the cold. We will need warm clothes! At least the sun will shine in the mountains, whereas low stratus will block out the sun in the valleys. So if you want to enjoy long sunny spells, you will have to spent some time in regions at higher altitudes. The temperatures, however, will be freezing cold.
