After a round of moderate thunderstorms moved across Minnesota on Wednesday morning, another wave of more intense thunderstorms is expected to roll across the Northland starting Wednesday afternoon and continuing into the evening.
The National Weather Service in Duluth said there is an enhanced risk of widespread severe storms that are likely to be destructive, including hail up to baseball size in some areas and winds to 75 mph — similar to storms that felled trees and powerlines Monday evening across the region.
Isolated tornadoes and localized flash flooding, especially in areas that received heavy rain on Monday, also are possible.
The storms are expected to develop in far northern Minnesota and move southeast into Wisconsin by evening. They are expected to spread across Koochiching, Itasca and northern St. Louis counties, including the Iron Range, from 1-4 p.m. Wednesday; hit Aitkin and Carlton counties, as well as the Twin Ports, North Shore and Northwestern Wisconsin, from 3-6 p.m.; then move into central and northeastern Wisconsin through 9 p.m.
