More Strong Storms Forecast for the Holiday Weekend

More thunderstorms are expected this holiday weekend, this time in western South Dakota. Thunderstorms are possible this afternoon, with an isolated strong to severe storm not ruled out. Then, by this evening and into tonight (Saturday night), storms in Montana and Wyoming are expected to push eastward, bringing the primary threat of damaging winds with isolated hail. The tornado threat looks to be mainly in Montana, but you cannot rule out an isolated tornado spin-up. The best chance for severe storms will be across west-central and northwest South Dakota.
