Swarms of Storms. NWS Doppler at 6:09 PM shows the first wave of storms pushing into Wisconsin, but more heavy storms are lining up over central and western Minnesota. Plan on a noisy night, with T-storms spilling over into much of Sunday as a slow-moving cool frontal boundary limps across the state.
Flash Flood Watch Central Minnesota. NOAA has issued a watch for central Minnesota into Sunday morning, where the ground is waterlogged from 1-3" rains, and more heavy showers and "training" T-storms will increase the risk of flash flooding overnight. Details:
