The oppressive humidity will last for one more day: today. But as it leaves it will do so with a “bang” as in thunderstorms, strong gusty winds and heavy to torrential rainfall. I would expect around .75" to 1.25" rain on average, meaning some get less, some could get a quite a bit more. Mostly beneficial rains with some runoff of course.
Most of the storms and rain will occur between Noon and 8 pm. The front is slow moving, so the showers and storms could linger for a while this evening. The day will start off really nice with sunshine but the clouds build and increase. It will feel rather hot this morning. If the clouds hold off until around noon (which I doubt at this time), then temperatures could soar to the upper 80s. Right now middle 80s seems reasonable given at least partly sunny skies and very warm temperatures in the 70s to start. It doesn’t take long to warm things up 10 degrees, and we will get enough sunshine to do just that.
Once the front moves through tonight, the showers end and we have 2 really nice days ahead for Tue and Wed. Thu may end up being nice, but warmer/humid air will try to return, so the chance for some showers or a thunderstorm will be present, esp. the further SW you go.
Friday, another frontal system approaches bringing a chance for showers/storms, but Sat looks mainly dry right now, and Sun a strong cold front approaches our area, with potential for strong to severe storms possible. It will be warm and very humid over the weekend. But behind this Sun cold front will be much cooler and refreshing air.
Monday: Partly sunny then showers and storms. Some could be strong to severe. Heavy rain. Very warm and very humid.

Wednesday: Beautiful with sunshine and some clouds.
Thursday: Mostly sunny then chance for a shower or storm. Warmer.
Friday: Partly sunny. Very warm and humid. Chance for showers and a thunderstorm.
Saturday: Sun and clouds. Warm.
Sunday: Partly sunny then showers and storms likely. Very warm and humid.
