36th British & Dutch Championships 2025 Krusevo - Weather Forecast 14th July

 

Summary of the Day forecast

Light west winds above 2200m, and light ESE winds in the Valley. 

West wind drops by 5kph and moves higher.

Convergence line across the mountains of Krusevo.

High pressure drops, and Humidity drops, and temperatures increase further comparing to the previous day, meaning that we will have stronger thermals than yesterday and easier to be broken inversion (ecpected at 2200).

At first Cu appear above high ground, half an hour later than yesterday and with higher cloudbase. At this time there will be spreadout and Cu Congestus clouds in the west and NW with top of clouds at 5.500m that may create shadow in the valley and have impact weakening the conditions after 16.00h.

After 14.00 we have Cu clouds in the valley with cloudbase 3500m+. To the south the Cloudbase will be lower, as more humidity is expected in the area of Bitola, and thermals there will be smoother in the south side of the hills in the middle of the valley.
