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.
There is a risk of strong to severe thunderstorms this afternoon into the evening over portions of southeast MT and northeast WY. Large hail, strong wind gusts and very heavy rainfall rates are the primary threats.
A strong weather system is expected to move into the region by late Friday and impact the weather through the weekend and possibly into early next week. This system 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. Still plenty of uncertainty with how this system will play out. Stay tuned to the forecast, especially if you have outdoor or travel plans late this week into the weekend.
