Soaring Weather Forecast Aetheria pre PWC Aug 21st 2024

 

Summary of the day - General Weather

After the front passing, a better competition day is expected.

However, the unstable air has not left yet and will give a lot of showers all around us in the North (50km) at 14:00h in the West mountains of Pindos at 15.00 and in the east mountain ridges of Edessa, Vermio and Olympos which will be visible from our area but will not affect us directly. But after 15.00 we expect to have shadow in our valley and conditions will weaken.

The very wet ground in our valley combined with the increased solar radiation of 800w/m2 will start the day early at 11.00 with the first Cu clouds appearing around 12.00. as the day evolves, more clouds will develop in the valley and after 15.00 we will have increased coverage (60%) and horizontal overdevelopment. We expect a second cloud cycle after 15.00 and the conditions will start declining after 16.30.

The temperatures will drop and Winds will be light North at all levels, colder but with 40% humidity.
