| episode_narrative | Multiple rounds of thunderstorms impacted portions of Southeast Michigan on June 18, 2025. The first round consisted of sub-severe pop-up thunderstorms during the morning hours. These produced pockets of heavy downpours but otherwise brought some relief to areas that had seen relatively dry conditions in recent days. Showers expanded in coverage across the southern part of the state by late morning to early afternoon as a disturbance aloft ushered in a more organized cluster of thunderstorms. These were also sub-severe, but the presence of environmental vorticity caused a weak tornado to quickly develop as several outflow boundaries collided near Fraser in Macomb County. These storms also produced torrential downpours. Nearly stationary storms dumped 3 to 5 inches of rain over a localized area in central Macomb County where flash flooding occurred early in the afternoon, closing roads and leading to several water rescues. A lull in activity occurred during the mid afternoon before a third round of thunderstorms arrived in the evening as a low pressure system approached from Indiana. This line of storms caused isolated occurrences of wind damage across southern parts of the state. |
