Is a hot spell about to send temperatures soaring in Denmark?

A high-pressure front, which was responsible for the weekend’s summer weather, could be about to push temperatures even higher.

Although the midsummer weekend, which Danes mark with traditional Sankt Hans Aften bonfires, proved to be a dry and sunny one this year, temperatures remained comfortably cool.

But the front system, which is comprised of warm air, and strong sunshine could combine to make things feel a lot hotter in coming days.

That is because the high-pressure front which was over the country on Saturday and Sunday has now moved to the northeast, bringing wind from the southeast and east – and subsequently hot weather from those parts, TV2 reports.

Up to 30 degrees Celsius is predicted in some areas, according to the broadcaster and meteorological agency DMI.

Southern Jutland in particular is expected to see mercury rising towards 30 degrees on Tuesday afternoon, before the hot weather moves east, reaching Zealand and Lolland on Wednesday.

Wednesday is forecast to be the hottest day of the week, with the Copenhagen area, northern Zealand and Falster in particular likely to be in for a sweaty day.

The west coast of the country will have cooler weather on Wednesday, however, with colder air moving across the country from the west. Depending on how quickly that air reaches the eastern part of Denmark, the heat may not be as marked as is currently forecast.

Theoretically, the coming hot air could feel as warm as 35 degrees Celsius – but wind and cloud cover will temper that to some degree, TV2 writes.

DMI defines a heatwave (hedebølge) as a period of at least three days in which the average maximum temperature recorded in more than fifty percent of the country exceeds 28°C.

That is different to the standard used by the World Meteorological Organization, which defines it as five or more consecutive days during which the daily maximum temperature surpasses the average maximum temperature by at least 5°C.

However, the coming hot spell of weather is not currently forecast to last long enough to meet either definition.

How much will it snow in Denmark this weekend?

Winter weather arrived in spectacular fashion to coincide with the beginning of December this week. The weekend could bring more snow to parts of the country but probably less disruption than recent days.

Recent snowstorms disrupted North Jutland in particular and Denmark in general, and more cold weather can be expected this weekend albeit severe, according to forecasts.

“We won’t see the Ragnarok-like weather we’ve seen in some places recently again this weekend, but it’s now winter weather and it has also snowed in several places overnight,” said meteorologist Frank Nielsen of the Danish Meteorological Institute (DMI).

Cold weather on Friday and a low front across the North Sea will bring clouds and precipitation across Denmark from the west, Nielsen said.

That will materialise as cold rain or sleet in many areas but probably snow in North Jutland, he said.

“There could be between five and ten centimetres of snow north of the Limfjord,” the meteorologist said, referring to the waterway that cuts across the northern part of Jutland, including main regional city Aalborg.

“In the southern part of the country, an equivalent five to ten centimetres of rain could fall,” he added.

Friday’s temperature will be between freezing point and five degrees Celsius, with the north of the country falling in to the lower end of that range and the south the warmer end.

Mist and fog is forecast this evening, caused by various weather fronts moving over Denmark.

That could still be felt on Saturday morning, though it is likely to be a little warmer at 2-6 degrees Celsius. Mild winds could make that fell chiller, but snow is unlikely.

Sunday will see the temperature drop again, to 0-4 degrees Celsisu. Snow is possible, particularly on eastern coasts.

Strong winds in the east of the country and along the coasts will result in a “rather cold 24 hours,” Nielsen said.

Nighttime temperatures are expected to drop below zero throughout the weekend. Motorists are therefore warned to be alert to icy road surfaces.
