I've just completed a major rewrite of the Interactive Forecast Map at
http://www.geoffschultz.org/weather_map.php . The web site can now display many of the charts, radar images, satellite photos, etc within a GoogleMaps pop-up window. You can still display the information in separate browser tabs if you want to be able to quickly compare charts. I think that most people will really like this new interface.
I've also highlighted the selected chart as you move the cursor over it. This is quite helpful when there are multiple charts in 1 area and it's not easy to determine which chart will be selected.
As this was a major rewrite and your browser is now doing a lot more work, there's a great chance that things will break depending upon the browser that you use, the version of the browser and which operating system you're using. I've checked it out on the majority of browsers on a Windows 7 system and an iPad, but there are lots of other combinations that I haven't checked. As a result I'd really like to get feedback from people as to how they like it and if they have problems.
