NEBRASKA, IOWA, AND MINNESOTA — A Mesoscale Discussion has been issued indicating a Tornado Watch is likely soon for portions of Nebraska, Iowa, Minnesota, Kansas, and Missouri, with an 80% watch probability already assigned to the discussion.
The Mesoscale Discussion covers a large red zone stretching from southern Minnesota through Iowa and into eastern Nebraska and northern Missouri, with the severe potential including EF-2 tornadoes with winds of 100 to 125 MPH, hail up to 3.50 inches in diameter, and wind gusts of 55 to 70 MPH across the outlined area.
80% Watch Probability Signals Imminent Tornado Watch Issuance
Mesoscale Discussion 501 carries an 80% probability of a Tornado Watch being issued, making the formal watch issuance essentially a near certainty across the outlined zone. The discussion cites increasing thunderstorm development across the region as the primary driver for the imminent watch, with conditions rapidly becoming favorable for organized severe storm activity across the multi-state corridor.
Communities within the red Mesoscale Discussion zone including Omaha, Sioux City, Des Moines, Fort Dodge, Storm Lake, Mankato, Minneapolis, Mason City, Lincoln, and Saint Joseph should treat a Tornado Watch as already in effect and take immediate preparedness steps.
