36th British & Duch Championship, Krusevo 2025, Weather Forecast 19th July

Summary of the Day forecast

Tomorrow seems a slightly better day, as thermals are expected stronger and the max lift will reach 2200m

It seems that yesterday thermals did not break the first inversion of 1400-1500m, at least during the competition task. The sun energy was not enough for fast ground warming and there was a delay in thermal conditions and thermals developed slowly with big cycles. Tomorrow seem better on this matter, as thermals will be stronger faster in the day, with more regular cycles and peak at least one and a half hour earlier.  

Comparing basic parameters, barometer is stable, humidity is dropping 5% and temperatures increase with a contrast of 13 C. Triggering is better than yesterday and it seems that the first inversion of 1400-1500 will not exist tomorrow.

 The day seems more regular for Krusevo, as frontal impact has left to the east and we have NW winds above 2200m and light ENE winds in the valley.

Temperature range DT: 18-31 = 13C suggesting good triggering of thermals to the ground and more organised to a lower altitude.

Dewpoint / time: 6,5 C in the valley 

Humidity: at 20% dropping by 5%. This will increase air density and thermals will be stronger.
