What is a 4Warn Weather Alert?
We issue a 4Warn Weather Alert when we’re expecting weather conditions that will be inconvenient to our viewers.
Why did we issue alerts for Monday and Tuesday?
Monday
A Slight Risk for severe weather covers nearly all of southeast Michigan on Monday as an approaching disturbance interacts with unstable air and increasing humidity. Scattered thunderstorms could develop later this afternoon and evening.
These storms will have the potential to produce:
- Damaging wind gusts
- Large hail
- Locally heavy rainfall
- Isolated tornadoes
The primary window for severe weather is expected between 4 p.m. and 8 p.m., although a few isolated storms could develop earlier in the afternoon.
Rain and thunderstorms may also linger into the late evening hours.
Tuesday
The severe weather pattern is expected to continue Tuesday with another Slight Risk (Level 2 out 5) covering all of southeast Michigan.
Warm, unstable conditions will clash with an approaching cold front and once again support thunderstorm development during the afternoon and evening hours, especially between 2 p.m. and 8 p.m.
Tuesday’s storms may again be capable of producing:
- Damaging wind gusts
- Large hail
- Heavy downpours
- Isolated tornadoes
Make sure to monitor our forecasts closely and have multiple ways to receive weather warnings during both days.
