Weather Temperature difference of over 20 degrees in some places over a small area

On Monday morning, there were sometimes massive temperature differences over a small area in Switzerland. In some cases, they amounted to more than 20 degrees, as MeteoSwiss announced.

"On a journey from Grenchen via the Jura to Delsberg, you start in a cold lake of air at minus five degrees and end in a foehn south-westerly wind at plus 17 degrees," wrote MeteoSwiss on the short message service X. As the crow flies, the distance between the two locations is less than 20 kilometers.

In the Föhn valleys with strong Föhn winds, up to 18 degrees were expected on Monday, in the lowlands between nine and 13 degrees in the afternoon. At an altitude of 2000 meters, MeteoSwiss forecast a temperature of around nine degrees.

But by Monday evening, temperatures below zero and snow were expected again at altitudes above 2,200 meters. By Tuesday morning, five to 15 centimetres of fresh snow were expected on the northern slopes of the Alps and up to 20 centimetres in places towards the west.
