Severe thunderstorms, flash flooding possible Wednesday

Severe thunderstorms are possible in the Northland from late Wednesday afternoon through Wednesday night.

The National Weather Service is predicting that heavy rainfall is possible, leading to flash flooding during the storms. The storms are expected to develop as a cold front moves eastward through the region. Once the storms develop, they are expected to quickly become severe. All of northern Minnesota and northwest Wisconsin could be affected, with the greatest risk occurring over central and north central Minnesota.

A flash flood watch is in effect from 10 p.m. Wednesday through Thursday morning in Carlton, St. Louis, Lake, Pine, northern Cook, Aikin, Cass, south Itasca and Crow Wing counties as well as northwest Wisconsin counties of Bayfield, Burnett and Douglas. 

Hail larger than 1 inch is likely and hailstones larger than golf balls are possible, according to the Weather Service. Damaging wind gusts of 60 miles per hour or stronger are possible and there is a small risk of tornadoes, mostly before 11 p.m.

The storms will move east or southeast with time, but may linger through early Thursday morning, according to the Weather Service.
