Doppler Radloop

Doppler Radloop is a gadget that you can use to easily monitor a weather radar right on your desktop in real time, which gathers information from a selected website. It is quite simple to install and set up.
The interface is based on a small frame that you can move to any location on the screen with the help of the mouse cursor.
In order to view the radar, you are required to accept the EULA from the Options panel available through the context menu. To get a better view of the map, the frame size can be increased.
The gadget provides a wide range of radar websites to choose from, together with several radar products, such as base reflectivity, base velocity, one-hour precipitation, and storm total precipitation. In the map you can toggle the real-time mode.
As far as customization goes, users may pick the default map overlays (typography, rivers, cities, counties, highways, warnings), enlarged image width, background color, and zip code (optional for local forecast). Furthermore, you can set the real-time mode to automatically activate at startup, and select the maximum number of frames to loop.
Thanks to the Windows built-in features, it is also possible to make the frame stay on top of other windows and adjust its opacity level. This way, Doppler Radloop becomes unintrusive when working in other applications, while allowing you to easily get a glimpse of the radar.
As expected, the widget uses a very low amount of CPU and RAM. It has a good refresh rate and does not cause the OS to hang, crash or pop up error dialogs. All in all, Doppler Radloop proves to be a nifty little application for getting weather information on the fly.
