Tornado Watch. SPC has issued a new watch (meaning conditions are ripe for isolated tornadoes) effective until 10 pm Tuesday night - including Breckenridge, Wheaton, Moorhead and Thief River Falls. This watch does NOT include the greater St. Cloud area. Storms should weaken later tonight, sweeping across northern and central MN (St. Cloud stands a better chance of strong storms/downpours than the Twin Cities later tonight).
