A weather system will bring a chance for rain showers to the region from late Saturday through early Sunday. The rain will develop across northwest Montana Saturday evening and night, then spread towards southwest Montana by Sunday morning. The best chance for rainfall amounts greater than a tenth of an inch happen to be along and just west of the Continental Divide. Further west towards Idaho, lesser amounts of rain are expected. It will be a chilly and wet morning across western Montana, but clearing is expected by Sunday afternoon or evening. There is a slight chance of a thunderstorm and the impact with that would be an isolated lightning strike and a period of heavy rain.
