The same system that spawned a severe thunderstorm in Helena moves out east today bring some gusty and and large hail.

Storms have already formed and will continue through the overnight hours in eastern Montana. Thunderstorms could pose the greatest threat to communities on the eastern border of the state, where we have already seen large hail with some of the more robust severe storms.

The Storm Prediction Center upgraded areas from Billings eastward into a level 2/5 (slight risk) for today. Gusty Winds are the main concern for the newly upgraded area.

Strong west wind will affect most of the state into Thursday. Wind gusts of over 45 MPH are possible for areas adjacent to the mountains.
