Weather report Wednesday
Fast development of cumulus, but the valley should be sunny, at least partially. Maybe around 2 more cloud-cover and congestus
The models show rain from 11h on, on certain spots.
Valley brise, moderate
1000m, 1500m easterly flow, especially along the ridges
2000m still easterly, or northerly
3000m north, 10kn
Probably the wind will enter from NW to Sedrun at 12h, and later North in the "North-South-Channels"
I think, that we can fly until 2 or later, but we have to stay very local. Local showers can kill the valid task...
