when on the weather the bottom right softkey text changes 2 setup. Click on it then select radar. From there click the option to change the url you just need to input your radar url. I tried it and it only works for the first time. My url would be
http://sirocco.accuweather.com/nx_mo.../inmSIRVA_.gif and it shows up fine the first time i load it but it never changes it always shows the time i first load it. I don't know if its a bug in the weather or not bc if i load the url in pie or opera it shows the updated pic.
I.E. i put the url in @ 6:45 on monday and check it it will always show the 6:45 radar status no matter if i try and refresh it hours later. Loading the same url outside the weather pannel shows the correct updated version. So i don't know if i am doing it wrong or not but thats supposed to be how to set it up.
If i set this pic up as my radar url it will always just show the time i first set it up I.E. 2:45am
