When looking at 500 hpa wind and geopotential height layer turned on, the GFS model does not display the isolines correctly. Most times the lines are not updated when selecting a new time. However, it appears everything works correctly when using the ECMWF model. I see this on my computer using Edge or Firefox as well as on my ipad app.

I often compare ECMWF and GFS models but have to go back and forth between the two. It would be extremely advantageous if the capability to place two models side by side that shows the same data, same coverage area, and same time.
