Also today 30 degrees in Uccle: heat wave is a fact and can certainly last until next weekend with peaks of up to 37 degrees | Weather & Science

Everyone knows that it is hot, but now that 30 degrees were measured in Uccle today, we are officially experiencing a heat wave. That reports our weatherman David Dehenauw.

The heat wave is expected to last until next weekend. According to Dehenauw, we are facing the “warmest week since the measurements started”.

Some P trains will be canceled on Monday and Tuesday due to the heat. This is what the railway company NMBS says. Travelers are advised to plan their trip before departure via the website or the NMBS app.

P trains run during peak hours. They complete one trip in the morning and the next one in the evening. They are parked outside for the rest of the day. At high temperatures it becomes in these trains too hot to drive safely. In addition, the oldest train sets are used for some P trains, which are: do not have air conditioning.

By reducing the number of trains mainly during peak hours, the risk of defective trains disrupting traffic on an entire line is reduced.

The maximums for next week have been adjusted slightly upwards by the RMI. The weather maps now show 37 degrees on Thursday and Friday.

This afternoon the mercury rises to 24 degrees near the sea, 31 degrees in the center and 33 degrees in Belgian Lorraine. Tomorrow we add a degree, with maximums of 25 degrees at the sea and 29 to 34 degrees inland.

And that trend continues for the rest of the week: Tuesday we go to 27 degrees at the sea, 30 degrees in the High Ardennes and 33 degrees in most other regions. In some cities and in Belgian Lorraine it can reach 35 degrees.

Wednesday there is 36 degrees as the highest temperature on the maps, and Thursday and Friday that is even 37 degrees. On Saturday we have to make do with 35 degrees again.

HLN weatherman David Dehenauw reports that we are in sight of the hottest week ever, with one next week predicted average temperature of around 27 degrees. “That would be between tomorrow and Sunday,” he says. “So far, the warmest week was the week from August 6 to 12, 2020, with an average temperature of 25.3 degrees. From August 6 to 13, the maximum temperature did not drop below 30 degrees in Uccle. It will be a dime on its side.”

We may also get the warmest night (measured between 8 p.m. and 8 a.m.). “The minimum temperature on Friday morning would be around 26 degrees lie. That is also a bit of a turn on its side, because the average margin of error for such a period is 2 degrees. And the warmest night to date was July 4, 2015, with 24.4 degrees in Uccle.“

Also remarkable: everything indicates that we will break three daily records from the legendary summer of 1976. On June 24 (32.8 degrees), on June 25 (33.6 degrees) and on June 26. The hottest June day ever was June 27, 1947. It was 36.8 degrees. 36 degrees are forecast for Uccle on Thursday (with margin of error). “It is not impossible that we will also break that record, but it is not a basic scenario at the moment,” Dehenauw added.

There are between 8am yesterday and 8am today 26,006 lightnings (flashes) observed. This was reported by HLN weatherman David Dehenauw. This involved 21,210 cloud-to-cloud lightnings and 4,796 cloud-to-ground lightnings. Quite a few, though no record. “We are certainly not in the top five,” said Dehenauw.

There were a total of 12,195 lightnings observed in Flanders13,758 in Wallonia and 53 in Brussels.

An active thunderstorm caused a lot of nuisance in various parts of the country last night. There were heavy rain, fierce lightning strikes and large hailstones reported from West Flanders to Limburg. The storm caused some damage, especially in South-West Flanders and at the Graspop festival campsites in Dessel (Kempen).

Also Graspop Metal Meeting in Dessel did not escape the thunderstorms that passed over our country last night.

Nearly 10,000 lightning discharges were recorded during last night’s thunderstorm. This is evident from preliminary figures reports our weather woman Jill Peeters.

Last night’s thunderstorms produced a total of 60mm of rainfall in the West Flemish Beitem54 mm in Ghent (Campus Sterre) and 49 mm in Roeselare. Our weatherman David Dehenauw reports this.

This morning the last showers and cloud fields will move away to the northeast, after which it will be sunny and very warm again. The RMI predicts temperatures of more than 30 degrees at least until Saturday. Code yellow for the heat will be in force throughout the country until at least Thursday, with the exception of the coast.

Today are the maximums around 24 degrees at the sea, 31 degrees in the center and 33 degrees close to the French border. Local thunderstorms may occur again in the late afternoon and evening. Tonight and tonight the chance of showers and thunder will decrease again and it will become partly cloudy. The minimum temperatures are between 17 and 21 degrees.

Tomorrow It will be very warm again with maximum temperatures around 25 degrees at the sea and between 30 and 35 degrees inland. It will be sunny with some cloud fields at times. There is a small chance of a thunderstorm in the evening.

Tuesday it will be sunny with fields of high cloud. The maximum temperatures are between 29 and 33 degrees. Also Wednesday and Thursday it is sunny with high clouds. The maximum temperatures are then between 31 and 36 degrees.

Friday it will be sunny and sultry, with temperatures of 36 degrees or even more in many places. Cumulus clouds will gradually appear and thunderstorms may appear in the afternoon or evening. Saturday we get an alternation of sun and clouds, with sometimes rain or showers. The maximum temperatures are around 32 degrees in the center.

It will be over the next fourteen days gradually less hot, with early July more pleasant temperatures around 25 degrees in the center. It will probably remain dry most of the time with plenty of sun.

The thunderstorm that will pass over the country on Saturday night will cause flooding in several places in South-West Flanders. Read more here.

In West Flemish Sint-Baafs-Vijve the RMI recorded no less than 42 millimeters of rain in just one hour. That is the highest intensity in the measurement network.

Lightning struck the roof of a house on the Ouburg in Dendermonde during the night from Saturday to Sunday. This immediately caused a roof fire, which forced the fire brigade to arrive on site. The damage to the home is significant. The family was present at the time of the impact, but was able to leave the home in time. Read more here.

“The scattered thunderstorm with locally high precipitation intensities is moving northeastward. There is enough momentum in the showers to avoid flooding in most places, but locally it cannot be ruled out,” reports our weatherman David Dehenauw.

“Hail of up to 1-2 cm may occur very locally, but not in most places. It will become drier from the southwest and it will become dry in many places in the late night or early morning,” it said.

In Zandbergen, East Flanders, beautiful lightning bolts can sometimes be seen, as the photo below from a reader clearly shows.

The heavy thunderstorm may have caused a power outage in the municipality of Heers (Limburg). Kristof Pirard, the mayor of that place, reported this on Facebook.

Fluvius is now aware of the power outage and is investigating the cause.

The thunderstorm is here and there accompanied by hail showers, as in Dadizele (West Flanders). This sometimes produces large hail, as one of our readers shows.

The storm has now also reached East Flanders, as images from our readers from that province show.

In Wingene, West Flanders, a beautiful bolt of lightning illuminates the sky this night. We received this image from a reader.
