The extensive low pressure system with its core over northwestern Europe, which also influences our weather, is now expanding towards the Iberian Peninsula. On its front, very warm air is being brought from the southwest from Spain and the western Miterranean to Switzerland.

30 degrees on Tuesday
The temperature in the free atmosphere at 850 hPa, or at around 1600 m above sea level, is often us as a measure of the temperature of the air mass – unaffect by the warming and cooling of the earth’s surface. Around 20 degrees is forecast for Tuesday. You can find a detail classification of this in the report publish here yesterday.
Contribution
.
The temperature in the lowlands will also rise accordingly. Since the maconia mobile database air mass is still relatively dry at first and – despite high cloud fields – the sun’s rays can heat things up, temperatures of 28 to 30 degrees are expect in the lowlands, and locally even over 30 degrees. In the Alps, a moderate foehn current will also develop.
Thunderstorms and Sahara dust from Wnesday
From Wnesday, two “disturbing factors” come into play, which also cause an increase in uncertainty in the forecast:
On the one hand, the air being suppli is becoming increasingly humid and the risk of thunderstorms is increasing. In the unstable and very warm air mass, strong thunderstorms are also to be expect in some places.
On the other hand, the air mass suppli is increasingly coming personaliz email: how to optimize your campaigns? from North Africa and is likely to be enrich with Saharan dust at higher altitudes. It is difficult to prict how much and how strongly this will affect sunshine and cloud development. As a result, the temperature forecast is also subject to certain uncertainties.

And what happens next?
Between Thursday evening and Friday evening, a cold front will cross Switzerland from west to east. On the one hand, it will bring widespread showers or thunderstorms, and on the other hand, less warm air will flow in behind it. According to the current model forecasts, however, the cooling will only last for a short time. It is becoming apparent that a high pressure area will
