Flymaster Open 2024 Krusevo Soaring Weather Forecast Sat July 13th

 

Summary of the day

• Similar day to yesterday maybe with slightly less powered thermals
• Barometric Pressure drops 1mb and humidity drops 2% 
• Small increase of higher NW winds
• More dust in the low level <1000m will delay the day to start by half an hour. (13.30h) and less sun energy to the ground - long thermal cycles.
• Ideal Take off 13.30h
• Peak of the day 14.00-17.00h
• 3h duration of potential Task

More Details

Barometer

The barometer will drop to 1003mb by 1 mb, tendency to break inversions but air less dense and possible increase of local winds

Temperatures

low T =26 C(higher than yesterday)

High T = 37-38C (higher than yesterday by 1 degree)

DT=12 C enough instability at higher altitude but less temperature contrast on the ground, meaning thermal cycles will last more.

Dewpoint

in the valley the DP=8,5 C similar to yesterday. 

Humidity -2%
