Today's Weather: A blustery, rainy day that 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 a few of you out there who've already popped your brolly in your bag. We're in for a classic, fickle Danish April day, and if you're planning to head out – perhaps to cast your vote – then you'll need to be prepared for a bit of everything. This isn't one of those days where you can rely on it staying the way it started.

From grey skies to a westerly wind: how the day will shape up

It's typical to wake up to a morning that might even have a glimmer of sun. But steady on. 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 rather blustery afternoon. It all starts with a front moving in over Jutland and slowly working its way east. Through the morning, most can expect a spell of persistent rain, and by the afternoon, things get properly interesting. The wind switches to the west, and the temperature starts to drop 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 still stick with the good old portals. But whichever service you use, all the warnings point the same way: it's going to get cold enough that the driving rain could change character at some point.

Election Day weather: Funen and Zealand need to watch out for sleet

Let me be straight with you, because I know lots of you are heading out to vote today. If you live on Funen or in the capital area, this is especially relevant. The models show that when the front reaches the eastern parts, the air gets so cold that this rainy day could end with hail and sleet. I've read a few of the local updates, and the risk is highest between about 4pm and 6pm. So if you're queueing outside a polling station, it's well worth having a hat with you – or at least a sturdy windproof jacket.

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

• Central and West Jutland: You'll get it relatively early. Rain in the morning, but it'll clear up in the afternoon. You'll still feel the wind gusts, though.
• Funen: You're caught in the tricky bit. Expect rain turning to sleet. It'll be the coldest part of the country this afternoon.
• Zealand & Lolland-Falster: Get any 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 to people in the supermarket or out and about, someone always asks: "Morten, can you trust those 14-day forecasts?" And my answer is always the same: they give you a good idea of the trend, but the last 24 hours are what really decide things. Right now, it looks like we can expect a slightly quieter weekend, but we've got to get through this change first. I can promise you one thing: you will 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: get the big umbrella out, pack an extra jumper, and remember, even though it looks grey now, it's only weather. We'll get through it.
