Weather fronts

[Kel]

The weather model in the game is very good.
In the following screenshot the northernmost cold front is finely figured. However there seem to be an awkard situation with the two other, in the middle
As far as I know, it is not possible that two weather fronts overlap like here. (If I remember well), the atmospheric pressure at a given place can not be at the same time both High and Low. As far as I know Depressions tend to be pushed around (+modified by coriolis effect) by the HP zone.
Am I right? Could something be done to avoid this - and what is more important, the underlying effects (humidity, temperature, air & ground quality und so weiter) ? thank you.
