Boundary Pushing Through, Getting Cooler Soon: Southeast Weather Forecast – 8/17/22

Over the next couple of days, we have a cool and wet pattern set to take hold across the Southeastern US. Today, we have a boundary set up across the area, with warmer weather to the South, cooler to the North.

With a cold front sagging across the Southeast, rainfall is forecasted for a good chunk of the area, seen in the green markings on the above map.

In addition, since the boundary shows us where we have a difference in temperature, we can see the strong difference on the anomaly map.

Significantly cooler weather will be observed today in the Northern half of the region, while the Southern half or so will still see average or above average temperatures.

Heat will be an issue for some, with heat indices hitting around 105F in some of the red areas in the Southeast. We don’t expect to see any heat advisories today, but it’s a possibility.

The map for tomorrow is very different, and as the boundary pushes South, pretty much the whole area is going to be under a cooler than average spell.

With the exception of far Southern Georgia and Florida, we’re all finally going to see some cooler weather. Significantly below average, as a matter of a fact. Some portions of AR could see around 20F below average!

Areas with heavy rain during the day will struggle to hit 80F, while most in the region should see mid to upper-80s.

The GEFS mean rainfall is around 1-2” during the next couple of days, and that’s an average between the extreme members. Some people will see more, up to 4” as an extreme, while some may stay dry. Ultimately, a wet, soaking pattern is forecast to occur later this week across most of the Southeast.
