Potential Storm System Late Week

Active weather continues through the week, including potential for severe thunderstorms beginning Thursday. Make sure to monitor the forecast if you have outdoor or travel plans.

A strong weather system looks increasingly likely from late Friday through the weekend and possibly into Monday. This is a strong slow moving system that has the potential to produce widespread precipitation for multiple days, strong winds in some locations, and even mountain snowfall (Beartooth Highway impacts). Severe thunderstorms are possible Friday and Saturday. There is still time for the track of this system to change. Make sure to stay up to date with the latest weather forecast this week, especially if you have outdoor or travel plans late this week into the weekend.
