Severe thunderstorms are forecast to develop this afternoon and intensify across western portions of the Watch. An initial linear cluster of severe thunderstorms is forecast to evolve into a bow echo as it matures and moves into the western Dakotas this evening. A corresponding intensification of the severe-wind threat is expected with widespread severe gusts expected and 80 to 100 mph gusts likely in localized swaths. Large to very large hail may also occur with storms that can develop ahead of the squall line. A tornado is possible with the squall line.
