Minnesota Storm Alert: Severe Weather Looms Friday
12 Sep
Summary
- Severe storms most likely across northern Minnesota Friday.
- Tornado threat peaks around 6-7 p.m. Friday.
- Hail and damaging wind threats are centered in central MN.
Severe weather is expected to impact northern Minnesota on Friday, with the potential for tornadoes, damaging winds, and large hail. The Storm Prediction Center has adjusted its outlook, downgrading southern parts of the state to a marginal risk while maintaining a slight risk across northern areas.
Initial supercells may produce large hail, with a possibility of isolated hail of 2 inches or more. The storm mode is predicted to transition to clusters, increasing the threat of scattered strong winds. Tornado probabilities are not high but are forecast to peak around 6-7 p.m. Hail probabilities are highest between 4-9 p.m., particularly from Fergus Falls southwest to Bemidji.
Damaging wind threats are more likely between Alexandria and Grand Rapids, with this risk peaking around 8 p.m. This aligns with forecasts from models like StormNet and HRRR, and the National Weather Service in Grand Forks, which indicates the severe threat is centered between Grand Rapids and Bemidji, extending southwest to Park Rapids, Wadena, and Alexandria.
