Today’s weather: A blustery, rainy day could end with hail – here’s what to expect on election day

I'm sitting here looking out the window, and I can almost guarantee there are already a few of you out there who've popped an umbrella in your bag. We're in for a classic, fickle April day today, and if you're planning to head out – maybe to cast your vote – you'll need to be ready for just about anything. This isn't one of those days where you can assume the weather will stay the same as when you woke up.

From grey skies to westerly winds: how the day will unfold

It's typical to wake up to a morning that might even have a bit of sun. But don't get too comfortable. It won't last. I've been keeping an eye on the local forecasts this morning, and there's no doubt we're in for a pretty windy afternoon. It all starts with a front moving in over Jutland and slowly making its way east. Through the morning, most places can expect a spell of steady rain, and by the afternoon, things get interesting. That's when the wind swings to the west, and the temperature drops a few degrees.

I know we all have our favourite apps. Some swear by the precision you get with the newer weather apps, while others stick with the trusty old portals. But whichever service you use, all the warnings point the same way: it'll be cold enough that this driving rain could change its tune at some point.

Election day weather: Funen and Zealand, keep an eye out for sleet

Let me cut to the chase, because I know plenty of you are heading out to vote today. If you live on Funen or in the capital area, this is especially relevant for you. The models show that when this front hits the eastern parts, the air gets cold enough that this rainy day could end with hail and sleet. I've had a look at a few of the local advisories, and the risk of seeing that white stuff falling is highest around 4 to 6 pm. So if you find yourself queuing outside a polling station, it's probably a good idea to have a beanie on – or at the very least, a solid windproof jacket.

I remember an election a few years back, where the weather was exactly like this: half damp, half cold. Back then, people thought it was just a passing shower, but ended up standing there freezing for half an hour. Don't make that mistake.

• Central and West Jutland: You guys get it relatively early. Rain in the morning, but clearing up in the afternoon. Those wind gusts will still be noticeable, though.
• Funen: You're in the tricky zone. Expect rain turning to sleet. This will be the coldest part of the country this afternoon.
• Zealand & Lolland-Falster: Try to get your errands done before late afternoon. It's going to be wet, windy, and sleety in the evening.

Can we trust the long-range forecasts?

Whenever I chat with people at the supermarket or out on the street, someone always asks: "Morten, can you really trust those 14-day forecasts?" And my answer's always the same: they give you a good idea of the overall trend, but the last 24 hours are what really matter. Right now, it looks like we're in for a bit of a calmer weekend, but we've got to get through this change first. I can promise you one thing: you're going to need your umbrella today. That's not even a question – it's an order from someone who's had to change their shoes three times in a single day before.

Keep an eye on the weather radars around midday, because that's where you'll get the precise minute-by-minute picture. But until then: dig out the big umbrella, pack an extra jumper, and remember, even though it looks gloomy now, it's only weather after all. We'll get through it.
