Metro Detroit weather: Severe weather chances continue this week

Severe weather could arrive in next 24 hours

DETROIT – Garden-variety thundershowers have popped up in Tuesday's muggy atmosphere, but severe weather could arrive in 24 hours.

The 4 Live Radar has been showing several small, short-lived but intense downpours across the heart of the area this afternoon. A few lightning strikes have been noted, too. Otherwise, expect any storm activity to fade closer to sunset. Overnight lows will drop to near 70 degrees, with humidity staying with us.

An organized round of thunderstorms will move in during the morning commute on Wednesday. These storms should stay below severe limits, but expect to be slowed down on the morning drive.

Then, we get a bit of a break through early evening. A few thunderstorms will form as temperatures soar to near 90 degrees. Heat index readings will reach the mid-90s. Any of these storms could have damaging winds and large hail, and flash flooding and an isolated tornado are also not out of the question.

Events such as these are why we have Severe Weather Alert Radio Days throughout the spring. A NOAA weather radio is one of the best tools to alert you to overnight severe weather. If you have a radio, make sure it’s powered up with fresh batteries and programmed to your county. Be ready to execute your severe weather safety plan if the alert tone sounds. Then follow developments with our Local 4Casters app on your smartphone.

Expect a line of strong storms to move in from the northwest just after midnight to keep the severe threat going through the early hours of Thursday morning. We should be dry by daybreak, but weaker thunderstorms are still possible during the day on Thursday. Highs Thursday will reach the low to mid-80s, still with high humidity levels.

Check out the remainder of the 10-day forecast for a heads-up on the weekend.
