weather module adjustments for rain and snow

CHANGELOG.md

@@ -42,6 +42,7 @@ This project adheres to [Semantic Versioning](http://semver.org/).
 - Weather forecast now works with openweathermap for both, `/forecast` and `/forecast/daily`, in new weather module. If you use the `/forecast`-weatherEndpoint, the hourly data are converted to daily data, see issues [#1504](https://github.com/MichMich/MagicMirror/issues/1504), [#1513](https://github.com/MichMich/MagicMirror/issues/1513).
 - Added fade, fadePoint and maxNumberOfDays properties to the forecast mode [#1516](https://github.com/MichMich/MagicMirror/issues/1516)
 - Fixed Loading string and decimalSymbol string replace [#1538](https://github.com/MichMich/MagicMirror/issues/1538)
