This is typical when you have humid weather like this. The atmosphere becomes fairly unstable due to the “fuel” from the heat and humidity. It certainly won’t be raining all day Tuesday and Wednesday, but you may want to keep an eye on the sky during the afternoons.
As we head on for the end of the week, it looks like the strongest heat will begin to subside, as highs will likely be in the low to mid 80s by Friday.
