After the summer phase, a cold front brings about the changes in air mass that many are expecting. However, a sharp cooling cannot be expected from this – nor is the end of the drought.
The beginning of this week was also extremely hot in many parts of Switzerland. A daily high was also recorded at Stabio near Chiasso in Mendrisioto, with 36.4 degrees, reports the SRF. New annual heights were also measured in the eastern Föhne regions. The thermometer in Chur and Bad Ragaj climbed up to 35.1 degrees. Temperatures rose even higher in the west, although no records were set there.
In addition, during the scorching summer, the zero-degree limit reached hitherto unknown heights: on Monday night it climbed 5,184 meters above sea level and thus was 550 meters higher than Dufourspitz, the highest point in Switzerland. Also, according to MeteoSwiss and MeteoNews, the previous record of July 20, 1997 was replaced by a zero degree limit of 5117 metres.
the weather is hot
This Tuesday, with a cold front, there will be a change in air mass, which was already indicated yesterday evening – and was expected by many. However, it did not make it much cooler at night. With a cold front, there was hardly any rain in the low-lying areas, and “the clouds lay like a warm blanket over Switzerland,” tweeted MeteoSwiss. As a result, the morning temperature remained above 20 degrees.
It was sunny during the day and then it was dry. According to SRF, the temperature is 7 degrees lower than the previous day. In the north it could be up to 28 degrees today, in the south it could still be 35 degrees. According to the weather services, there should not be much change in the mix of weather with lots of sun, cumulus clouds and isolated showers at temperatures up to 30 degrees by Thursday.
Furthermore, it should continue to warm into August, the SRF forecast: a high temperature of 35 degrees is possible, but unlikely as of the current situation.
very little rain
MeteoNews reports that there were occasional large amounts of rain on Monday and the previous night, especially on the northern slopes of the Alps and in the Alps. The highest rainfall occurred in the Bernese Oberland, Alpstein and the Northern Grissons. According to the Meteorological Service, the region received more than 40 mm of rain at the local level.
Sometimes violent thunderstorms also had an effect: due to landslides, the Offen Pass, which connects Engadin with Val Müstair, had to be closed from Monday evening. The fault was rectified at around 12.30 pm on Tuesday.
However, MeteoNews predicts that large and widespread rain is not expected before August 1. It is most likely that there will be significant rainfall on Friday, but this should give a “temporary exemption” regarding the drought.
high wildfire risk
Due to the extreme drought, Alert Level 4 remains at “Greater Threat” over large parts of Switzerland. The highest alert level 5, “Very Great Danger”, is present at Fully (VS), Nikolai (VS), Reids (VS), Saas (VS), Simplon North (VS), Sitten-Siders (VS), Lottsburg Sudrampe. Area (VS) and Wisper Valley (VS).
