Switzerland will experience its first snowfall tomorrow, with varying amounts expected across regions. Up to 80 cm of snow is possible in the western Alps. While some areas in the eastern regions may see 10 to 20 cm, temperatures are forecasted to rise over the weekend, leading to melting snow. Jürg Zogg, a meteorologist with SRF Meteo, notes that the timing of the snowfall is slightly earlier than the average, but not unusual.
