Storm threat Wednesday, Thursday
We’re also tracking a severe storm threat in Southeast Michigan on Wednesday and Thursday, with the chance for isolated tornadoes, high winds, hail and downpours.
From Local4Caster Brandon Roux: Skies will be partly sunny to partly cloudy Wednesday, 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 Wednesday and Thursday. The peak heat of the afternoon may spark a few storms, but most of the wicked weather will be in Wisconsin and western Michigan later Wednesday 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.
