As we all know that XWidget uses AccuWeather service to get weather information. AccuWeather icons are different from the rest other weather service icons (Yahoo Weather, Weather.com etc.). But most icons available from artists on sites such as DeviantArt publish icons based on Yahoo Weather or Weather.com. Moreover these services are very widely used. So I collected some data on Icons and compiled them into a reference. This will be helpful for anyone using AccuWeather core with icons from other sources or those attempting to port a Rainmeter weather widget to XWidget. Hope it helps!
