Today's weather: A windy rainy day could end with hail – here's how election day will shape up

I'm sitting here looking out the window, and I can almost guarantee there are a few of you out there who've already thrown 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 a bit of everything. This isn't one of those days where you can count on things staying as they started.

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

It's the kind of morning where you might wake up to a bit of sun. But don't get too comfortable. It won't last. I've been keeping an eye on the local weather services this morning, and there's no doubt we're in for a pretty windy afternoon. It all starts with a front sweeping in over Jutland and slowly making its way east. Through the morning, most of us can expect a spell of steady rain, and by the afternoon, things get more interesting. That's when the wind swings around to the west, and temperatures drop a few degrees.

I know we all have our favourite apps. Some swear by the precision you get from the newer weather apps, while others stick with the trusty old portals. But whichever service you use, all the forecasts are pointing in the same direction: it'll get cold enough that the driving rain might turn into something else.

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

Let me cut straight to it, because I know a lot of you are heading out to vote today. If you live on Funen or in the greater Copenhagen area, this is especially relevant for you. The models show that when the front reaches the eastern parts, the air will be cold enough that this rainy day could end with hail and sleet. I've been looking at a few local reports, and the risk of that white stuff coming down is highest around 4–6pm. So if you're queuing outside the polling station, a hat – or at least a solid windproof jacket – wouldn't be a bad idea.

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

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

Can we trust the long-range forecasts?

Whenever I'm chatting with people in the supermarket or out and about, someone always asks: "Morten, can you really trust those 14-day forecasts?" And my answer is always the same: they give a good sense of the trend, but the last 24 hours are what really decide it. Right now, it looks like we're in for a slightly calmer weekend, but first we have to get through this changeover. I can promise you this – you'll 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 one 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 if it looks gloomy now, it's only weather. We'll get through it.
