GOES-16 GLM Lightning detection over Minnesota

May 12th, 2022 |

Wednesday, 05-11-2022, brought storm damage and copious amounts of lightning over Minnesota and parts of South Dakota, Iowa, and Wisconsin. The GOES-16 Geostationary Lightning Mapper (GLM) detected the flash extent density over these areas. A NEXRAD radar composite shows a large bow echo signature around 05-12-2022 01:25Z that spanned the entire lower half of Minnesota. Storms are still currently pushing through eastern Minnesota and northern Wisconsin and forecast to bring severe thunderstorms throughout the afternoon. There are also continuing threats of flooding in the Twin Cities and surrounding areas.
