Windy collects data from weather provider. They don’t do any calculation. They put in one place all data from IFS, GFS, etc... If there is somewhere an institute which can provide for free global front maps coming from their calculation, Windy could think to integrate potentially this map in their app,...
So far, front maps are available from a lot of weather national institutes, like IRM, MET, DWD, Meteo France,... They prepare them manually and then they propose an forecast of this map using models like DWD using ICON to forecast the front map evolution. Issue : starting point is done manually and it is a local front map, not global front map
