The disturbance that will cross the north of the Alps Wednesday night could dump four to eight cm of fresh snow on the Plateau Romand, according to a forecast by Federal Office of Meteorology and Climatology (Meteosuisse).
Then the snow will give way to a particularly cold wind.
The plains should be covered with a snowpack of a few centimetres. The northern Plateau could receive up to eight cm of fresh snow due to a cold draft in the region.
La perturbation qui a traversé nos régions cette nuit a saupoudré la plaine de quelques #flocons : 2 à 7 cm de #neige fraîche ont été mesurés à 7h ce matin selon les régions. #MétéoSuisse #meteo pic.twitter.com/qe29VpeSZK

On the other hand, on the shores of Lake Geneva below 500 m, as well as in the Rhône valley, the snow should not exceed three cm. It is more likely to rain or rain-snow at lower elevations, Meteosuisse reports.
The rest of the week will also be significantly colder due an influx of polar air.
On the plateau, the temperature could drop to -8 to -12 degrees Centigrade.
