Isolated tornadoes, damaging winds possible


DETROIT – We’re tracking a severe storm threat in Southeast Michigan on Wednesday and Thursday, with the chance for isolated tornadoes, high winds, hail and downpours.

Here’s what you need to know from Local4Caster Brandon Roux:

Skies will be partly sunny to partly cloudy later today, with highs near 90°F feeling more like 97°F in the shade. The oppressive humidity will keep those crazy heat indices in the upper 90s today and tomorrow. That peak heat of the afternoon may spark a few storms, but most of the wicked weather will be in Wisconsin and western Michigan later this afternoon. Isolated tornadoes are possible along with damaging winds and large hail.

Our severe threat for SE lower Michigan and southern Ontario will be more in the early or mid-evening, so be on your toes. There’s heat stress and storm threats later Wednesday evening with isolated flooding downpours and rough winds. Again, isolated tornadoes are possible.

We have a similar set up again Thursday, but the risk of a severe storm threat is marginal.

A series of weak disturbances passing over Pure Michigan in this unstable air over Metro Detroit keeps the problems of heat and storms around one last day. Keep those eyes to the skies with highs near 90°F, feeling closer to triple digits, with hazy sunshine coming and going. Spotty morning storms are possible Thursday, but more likely in that heavy heat of the mid-afternoon.
