Hi Filip. My results were from the same run, but on NOAA website I'm using the first sounding option.
GFS Model (1 degree, 0-240h, 3 hrly, Global pressure)

Now I know what is causing the difference

The fun thing is that @cloudy_ is writing in russian and is also trying to translate it in russian, which seems correct. The russian term is Атмосферное зондирование.

But the right term in bulgarian is аерологичен сондаж, атмосферен сондаж or simply сондаж. The word звук which now stands for sounding on the site is meaning sound in both russian and bulgarian.

Here is a material about the soundings written by the National hydrological and meteorological institute in Bulgaria:

Great to know we were able to pinpoint the reason. 1 degree model has very coarse grid (around 100km), I wouldn't recommend it much.

Only in this mode there is visualisation of the predicted superadiabatic layer on ground level. And it is quite accurate, especially in low wind situations and also in western Bulgaria in general.

Today I checked the forecast for tomorrow and again there is difference in the GFS soundings in NOAA and Windy for the same place and time. The displayed soundings are from the run at 00:00Z

And also the sounding in the bulgarian version of Windy is translated as звук, but the correct word is сондаж.

Best regards and thank you for the reply!

Now it's much closer, but still differrent. Especially the dew point line near the surface

Hi there! There is a huge difference between wednesday 22 may GFS sounding foreast for Sopot, BG displayed here and on the NOAA website.
