Flood watches are in effect through Tuesday morning, and the Storm Prediction Center has all southern Michigan under a "slight risk" area for severe storms Monday night. All of metro Detroit is at least under a "marginal risk" area.
We've had several rounds of rain over the past 3 days due to multiple pulses of energy riding along the northern edge of a stalled-out frontal boundary that's been sitting just to our south. Tonight, the front begins to lift north.
Upper-level dynamics, in combination with the front lifting north, will give us the chance of stronger thunderstorms returning tonight. The biggest concerns for impacts are damaging wind gusts and flooding. Some areas have had over 3 inches of rain since Friday, so any additional rain could lead to further flooding. A rain-soaked ground can also make it easier for trees to be uprooted from thunderstorm wind gusts.
Most of the computer models show storms arriving after sunset. However, a few isolated strong storms may develop well-ahead of that time frame, so be sure to check the radar on the WXYZ app before (or while) you're outside.
Additional showers are possible throughout Tuesday morning and afternoon, but shouldn't be severe.
We'll keep you updated on social media, our app, and on Channel 7.
