Today, same temperature inversion in the morning. With a comparison of temperature at Geneva airport weather station.
The 9km resolution of the ECMWF model does not allow to show this local effect.
Sorry there are 30 minutes between these 2 screenshots which explains the 2°C difference at WS.
@Gkikas-LGPZ @csabatatar Yes this happens often, it's a configuration error. The routine that draws those light gray circles does not know anything about the underlying radar data (over which it draws the circles). Sometime radar sites have incorrect range in the configuration (e.g. off by several kilometers), or the data can change. Plus, very probably I will be reworking the central/south american radar so probably this will be fixed to a degree :-), but still you can find these things often.
