A cold front currently extending from central Iowa to the Texas Gulf Coast will continue moving slowly east this afternoon and evening. A very moist air mass continues to be in place across the lower Great Lakes region. This front will provide the focus for the development of showers and thunderstorms this afternoon and evening. Severe thunderstorms are possible with damaging winds being the main threat. There is a threat of flooding as well which will be caused by heavy rains expected late afternoon and tonight with the showers and storms.
Localized flooding is also possible in urban areas such as streets and underpasses.
Spotter activation may be necessary tonight. A large area of rain moved into northern Indiana and southwest Michigan late this afternoon and will move into northwest Ohio this evening. Rainfall amounts could exceed two inches tonight in parts of the area. People living near streams or other low lying areas should listen to NOAA Weather Radio for later statements and possible flood warnings tonight. Ponding of water on roadways will likely result in hazardous driving conditions.
