It was ten days ago I first did a blog about the models showing hope for the end of the heat wave and it still looks like they were right.
The big upper level jet stream heat ridge of high pressure that has been parked over the Southeast U.S. for over a month is finally expected to flatten with its core moving out West as upper-level troughs move from West to East between now and early next week:
Meanwhile, at the surface the hot dry high pressure will be replaced by a “back-door Wedge” moving in from the Northeast down the Appalachians during the weekend and that is followed by a cold frontal passage on Monday from the Northwest followed by a cooler less humid air mass and fair weather high pressure bringing in more Fall-like temperatures at long last.
In the transition a stray shower possible on the weekend but most of us stay dry, better chance of a shower or thundershower Monday:
Rain chance only about 20% on the weekend and 40-50% Monday.

The drought has worsened over the past week with 100% of the state abnormally dry and areas of EXTREME DROUGHT in parts of Metro Atlanta:
