I have the same issue. Running Windows 10 on a desktop, Chrome, IE and Edge. When I close any of these browsers and come back to it later, the isolines I had previously set to display appear for about 1/2 sec then revert to "None". I have to go back into settings every time to reselect.

Re: Option to turn off the weather radar forecast
Please reconsider your approach to this. The future radar is inherently inaccurate and is by far the most annoying feature of your service. If you insist on keeping this feature, please add an option to turn it off. I have begun using a different radar app because of this. I like your graphical presentation and would return if this annoyance was addressed. On these threads, I have not seen anyone supporting the future radar, only complaining about it. Not sure why you added it.
