A change in the upper-level pattern will lead to a noticeable cooldown for the Southeast by mid-week, which will continue into the upcoming weekend. This pattern change has been consistently advertised on the global models, thus, confidence is high in this scenario.
The upper-level changes will send a cold front through the Southeast by mid-week. Behind the front, drier and cooler air will advect into the Southeast; temperatures will be 5-10 degrees Fahrenheit below average from Thursday through the weekend. Highs will drop into the low to mid 80s, with lows dipping into the 60s–a few 50s are possible across the Tennessee Valley by Friday morning. Along with cooler temperatures, humidity levels will decrease, which will make for very comfortable afternoons. The only exception is for areas closest to the coast and Florida. The cool front’s momentum will slow and will struggle to provide much relief for these areas.
Enjoy the break from the heat!
