Switzerland Weather: Polar Front Brings Snow and Arctic Blast – Latest Weather Radar
If you were out and about in Basel or Zurich on Saturday, you'll have felt it. That air mass moving in. Not just "a bit cooler", but that distinct, biting freshness that gets right into your bones. Now it’s getting serious. The polar front, which had already caused chaos in northern Germany, is now sweeping its full force into Switzerland. Anyone who thought spring was a done deal needs to tear up their plans pretty sharpish.
I was looking at the latest weather charts last night, as I’ve done for the last twenty years, and to be honest? Even the old hands among the meteorologists are tipping their hats to this change. It’s not just a minor cold snap. This is a turbulent shift we rarely see at this time of year. The models have been revised steadily downwards over the last 48 hours. What does that mean for us? It’s not just going to be wet; it’s going to be white.
Snow as low as the Central Plateau? Here’s how I see it panning out
Take a look at the current weather radar, and you can clearly see the front rolling in from the northwest. The classic 'bise' wind is showing its most unpleasant side. The key factor is the snow line. The forecasts are clear: the polar air is pushing the snow line down to around 600 metres today. By Tuesday night and into Tuesday morning, it could drop even lower. In plain English: in cities like Bern, Lucerne or St. Gallen, it’s not just rain in the air. There could well be a decent amount of snow settling. I’d wager that many people will be looking out of their windows tomorrow morning and doing a double-take.
For anyone shaking their head at this: yes, it’s unusual. But we’re used to it in Switzerland, where April does what it wants. Even so, this abrupt switch from what felt almost like summer back to winter is quite a statement. The authorities' weather warning is out there for good reason. This isn’t a “might-get-a-bit-chilly” warning; it’s a “watch-out-on-the-roads” warning.
Key points for the coming hours
- Road conditions: Icy patches and slush, especially in the morning. Summer tyres? A real risk, not just on the Gotthard.
- Temperatures: Highs of around 4°C. With the biting wind, it’ll feel comfortably below zero. Time to dig out the winter hats again.
- Snow line: Dropping to 600 metres and below. Even the Central Plateau and cities could see a white covering.
- Duration: The Arctic air will stick around until at least Wednesday. It'll only start feeling spring-like again towards the end of the week.
I’ve just had another look at the weather radar. Precipitation is really building up over the Jura and the Black Forest. That’s now heading straight for the Central Plateau. So if you have to go out this afternoon: expect a mix. Rain at first, turning to more and more snow as the cold air digs in. It’s going to get really treacherous this evening, especially in the transitional zones between 500 and 800 metres. Only one thing for it: stay calm, slow down and point the car heater at your feet – winter is making a brief comeback.
Tomorrow morning will be interesting. My bet is that the maps will be completely white by seven. Not just in the Alpine valleys, but in the conurbations too. So, folks, wrap up warm, look out for each other and maybe even enjoy the sight – after all, there’s something to be said for snow in April. But don’t forget to keep a shovel in the car if you absolutely have to drive. It’s going to be wild out there.
