While most of the storms look to just put down some heavy rainfall, there could be a couple of storms that produce damaging wind gusts. That will be the main risk as the storms move through on Wednesday afternoon and evening.

On the Fourth of July, areas of rain and storms will linger. We all have storm chances early on the 4th of July and late evening. Likely dry weather returns Friday through the weekend.

Thursday's severe weather chances aren't as clear. Rain and thunder will be ongoing as the day starts. The morning rain and thunder is expected to diminish toward lunchtime. More thunderstorms may develop during the evening as a cold front approaches from the west. The timing of the storms may impact some fireworks displays with the best chance of rain by 9pm and afterwards. Only spotty storms are expected before that, during the day, mainly west of St. Louis.
