Switzerland Weather: Polar Front Brings Snow and Cold Snap – Latest Weather Radar

If you were out and about in Basel or Zurich on Saturday, you would have felt it. That air moved in. Not just “a bit cooler,” but that sharp, crisp freshness that gets right into your bones. Now it’s the real deal. The polar front, which had already caused chaos in northern Germany, is now swinging its full force into Switzerland. If you thought spring was already locked in, you might want to rethink those plans pretty quickly.

I was checking the latest weather charts last night, like I've done for the past twenty years, and honestly? Even the seasoned pros among meteorologists are tipping their hats to this weather shift. It’s not just a minor cold snap. This is a turbulent changeover that we rarely see at this time of year. The models have been consistently downgraded over the last 48 hours. So what does that mean for us? It’s not just going to be wet; it’s going to be white.

Snow down to the Central Plateau? Here’s how it’s looking

If you take a look at the current weather radar, you can clearly see the front rolling in from the northwest. That classic east wind is showing its most unpleasant side. The key factor is the snow line. The forecasts are clear: the polar air mass is pushing the snow line down to around 600 metres as the day goes on. By Tuesday night and into Tuesday morning, it could even drop lower. In plain English: in cities like Bern, Lucerne, or St. Gallen, it won’t just be rain in the air. There could be a proper dump of snow that settles. I’d wager plenty of people will be looking out the window tomorrow morning, rubbing their eyes in disbelief.

For anyone shaking their heads right now: yes, it’s unusual. But we’re used to it in Switzerland – April does what it wants. Still, this abrupt switch from what felt like almost summer right back to winter is quite a statement. The official weather warning is out there for good reason. This isn’t a “maybe-it’ll-get-a-bit-chilly” warning; it’s a “watch-out-on-the-roads” warning.

Key points for the next few hours

• Road conditions: Icy patches and slush, especially in the morning. Summer tyres? A real risk, not just on the Gotthard.
• Temperatures: Highs around 4 degrees. With the icy wind, it’ll feel well 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 coating.
• Duration: The polar air is sticking 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 into the Central Plateau. So if you have to head out this afternoon: expect a mix. Rain at first, then turning more to snow as the cold air digs in. It’s going to get properly slippery this evening, especially in the transition zones between 500 and 800 metres. The only advice is: take it easy, 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 o’clock. Not just in the Alpine valleys, but in the urban areas too. So, folks, wrap up warm, look out for each other, and maybe even enjoy the sight – after all, this much snow in April has its own charm. 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.
