7 October 2019

The second week of October opens with a first weak autumn snowfall that has reached the mid-mountain (lower limit at around 2,000 meters in the Upper Valley) whitening the landscape. Let's see in detail the weather evolution.

The high pressure on the Middle Atlantic tends to strengthen until Friday with a rise in temperature to a decidedly warmer climate tomorrow, but with a probable incursion disrupted on Wednesday. After the snowfall of this night, today the day will be sunny with some initial residual cloudiness, located in particular on the ridges. The strong winds at altitude are attenuated until they become weak in the afternoon; also the foehn in the valleys is expected to be attenuated. Thermal zero from 2100 meters up to 3300 meters.

On the TMB and on the medium altitudes, the snow fallen above 2,000 meters, should quickly melt, but beware of the shady slopes (north) where it will be possible, especially early in the morning, to find ice on the ground. It could therefore better to prefer sunny routes and paths, at least for the days of today and tomorrow
