New rinsing in the middle of the mountain, and new softness!

This Thursday, the sunny moments are replaced by increasingly thick high cloud periods. After 23.00 and around By 04:00 to 05:00 the disturbance passed over the Hautes-Alpes, while the weather remained dry elsewhere. The rain-snow line is close to 1400/1600 meters from east to west. We generally expect 2 to 5 cm of snow higher up or even 10 cm at high altitude in Champsaur/Dévoluy.

Friday, the weather remains dry but temporarily cloudy over the Alpes-Maritimes. Further north, broader clouds dominate. Precipitation resumed in the Hautes-Alpes and the north-eastern part of the Alpes de Haute-Provence in the late morning and continued in the afternoon. They are limited at the end of the day to the Hautes-Alpes, after which the weather dries up everywhere at the beginning of the evening.

The rain-snow line rises pretty quickly everywhere towards 1800/2000 meters, but rather 1600 meters around Briançon, or even 2300 meters at the end of the episode at Dévoluy.

We expect during this disruption:
– 15 to 20 cm of snow above 2300 meters west of Ecrins, 5 to 10 cm elsewhere or even 3 to 5 cm in Ubaye.
– 5 to 10 cm of snow around 1800 meters east of Ecrins, 1 to 3 cm before the rain everywhere else.

The sun fully dominates Saturday. The softness is exceptional as we will reach +11 to +16 degrees around 1000 meters and +5 to +10 degrees around 2000 meters. This type of weather continues Sunday, despite some cloudy patches around Ecrins, with temperatures remaining equally high.

The Pyrenees:

This Thursday, the weather is increasingly cloudy, but showers are practically absent during the day. At the end of the day, there will be unrest in the Basque Country. It concerns the Pyrénées-Atlantiques in the evening and the border ridges on the Hautes-Pyrénées side during the next night. Elsewhere, rainfall is anecdotal. Fortunately, because the rain-snow line will go from 1800/2000 to 2200/2300 meters quite quickly. We expect 5 to 10 cm higher in the aforementioned sectors.

Friday, we still have some cloudy periods at the start of the day (especially at the bottom of the chain) then they become more and more rare during the morning. The weather is nice in the afternoon and the sweetness is already there.

This softness will increase significantly Saturday. As proof, the map below of the 0 degree isotherm (elevation where zero degrees is reached) is modelled. It will reach … 4000 meters! A value worthy of an entire summer. Under a beautiful sun, sometimes obscured by high clouds, the temperatures will fly away up to +14/+18 degrees against 1000 meters and +7/+12 degrees against 2000 meters. We will keep these values ​​very high Sunday in weather that remained very sunny despite still some high clouds.
