Amazing season flip!

Large parts of Europe saw their hottest March day on record only a few days ago. Places like Germany 🇩🇪 recorded +27.2°C on 31 March 🥵

Now it is snowing with a bitter wind-chill 🥶

For reference, it wasn't just Germany that was setting heat records at the end of March.

Summer-style heat followed by winter cold like this is extremely tough on nature.
And this is why...

Arctic air had the express ticket to Europe.

Incredible setup for delivering the widespread and sudden cold plunge.

One extreme to another in less than one week!

Beauvais, France 🇫🇷 broke its monthly heat record on March 31 with a baking +24.8°C and then went on to beat its monthly cold record on April 6 with a chilling -6.9°C.

This violent season flip is brutal for flora and fauna. ImageImage
'But we can't just compare maximum temperature from one day to the minimum of another'

I hear ya. That is bad practice. This is how the maximum temperature from 31 March compares to maximum temperature of today (6 April).

Mot places AT LEAST 20°C colder - awaiting finalisation. ImageImage

Arctic air pouring through Europe right now. You can trace the source pretty much all the way to the North Pole!

Very well defined on satellite. ImageImage

Brace yourself ⚠️🥶

Arctic air is engulfing almost all of Europe in the next few hours. You should notice a massive temperature drop.

Snow is falling quite widely across parts of northern Europe as we speak.
This animation shows the wind chill temperature, a calculation accounting for strength of wind and air temperature.

Short story: it is going to feel extremely cold for April.
We can't be too surprised by cold and snow and April. This is not rare - it is actually common.

However, this level of cold is impressive. I would say this is a particularly strong Arctic outbreak. Overnight lows will fall below zero widely across Europe.

Arctic blast imminent for Europe ⚠️

This will come as a massive shock after record-breaking heat a few days ago.

One of the most impressive cold air outbreaks I have seen for a while.
April weather in Europe: 'I will do what I want'

Check this out, daytime temperature will be more than 20°C colder compared to the March heatwave from a few days ago.
Snow is expected. Could look quite impressive locally while it is falling.

Arctic blast incoming ⚠️ A huge temperature shock is on the way for Europe.

From record heat at the end of March, temperatures are going to tumble well below normal early next week. Yes, there will also be snow for some ❄️
The contrast from this week to next is almost a joke. One of the reasons I didn't make this post yesterday - nobody would believe it! 😅
A nice wave in the jet stream and the Arctic floodgates are open.

Very efficient transport of cold, perfect setup.
