DETROIT -

Thursday morning will be comfortable and mild, but heat and humidity will be building in the afternoon.  Low temps will be in the 60s at dawn.  Daytime highs rise to 90 degrees with partly sunny skies and higher humidity.  Added moisture means increased instability.  Thursday evening may have a few spotty showers and thunderstorms.

Scattered storms will be a pattern Friday and Saturday with highs remaining near 90.  Some storms will have heavy downpours and gusty winds.  A weekend cold front will bring more organized, widespread thunderstorms and showers by Sunday with highs in the middle 80s at the end of the weekend.
