Hole Switzerland is in a strong SW airflow, but our valley should be covered pretty good.
It looks like the unstable airmass produces overdevelopment from 14h on, starting little bit east of us (Gotthard). These overdevelopment could arrive Disentis at 15h, probably later.
Normal valley brises
2000m: The SW Wind will be noticeable, especially along the relief
3000m: 15kmh SW
4000m: 20-30kmh SW
Moderate-good thermals with nice cloud base (3200m)
