@wxgeek This is available, here with wind layer and isolines at 500hPa level, but they can overlay most maps. Adjust level and select More layers > Geopotential isolines Only Wind, Temperature, Humidity, Dew point are shown at this level, the other like Rain, Clouds, Pressure, Waves... are not modified, of course, by the altitude slider but can be overlaid by 500hPa isolines. With customized colors

@jhnelson24 Hi, this is not a bug, since on Radar layer you don't even have an option to have isobars turned on. Instead there is Lightning and sound, please see below - Isobars are not in settings, so they cannot be saved as default.

@Evil Isolines should disappear, because it is forecast for "some hour in future". Radar is history. So we decided to turn them off when you change to radar.

@Ftaute Yes a very very small bug. You can see it only with a microscope

Technically impossible at the moment
