The Southeast will have near- to slightly above-normal warmth this summer, according to the AccuWeather.com 2012 Summer Forecast. Meanwhile, some rain relief is in store, especially for Florida.
Cities such as Atlanta, Charlotte and Raleigh will be among those forecast to have near- to above-normal temperatures this summer.
It has been a very dry spring for the Southeast, which has allowed a strong dome of high pressure to set up over Florida. The worst drought conditions, exceptional drought, are gripping portions of Georgia and northern Florida.
With the pattern transitioning to El Niño, the ridge of high pressure should gradually break down this summer, according to AccuWeather.com Expert Senior Meteorologist Dan Kottlowski.
Near-normal precipitation is in store for much of the Southeast as a result.
While the most active severe weather is anticipated for the Great Lakes to the mid-Atlantic, AccuWeather.com Lead Long-Range Forecaster Paul Pastelok said, "Any fronts that manage to make it as far south as northern Georgia and the Carolinas could spark active storms."
In fact, near- to above-normal rainfall may be in store for interior portions of the Southeast, including far northern Georgia and upstate portions of the Carolinas.
Steering currents in the tropics will also be directed toward the East Coast at times, particularly late in the summer. This may leave the Atlantic Seaboard open to a tropical system hit.

Farther south, the pattern will change around for Florida with the return of showers and storms this summer that could help gradually cut into the drought gripping the state. Pastelok said that the Gulf of Mexico is warmer than normal, which should promote a typical, humid summer for the Sunshine State that will help support thunderstorm development.
There may even be a tropical system hit in Florida this season that could supply beneficial rain.
"If Florida remains dry through May and into June, then statistics would suggest a tropical hit in central or southern Florida," Kottlowski added.
As July draws to a close, a storm system swinging up from the Deep South will bring downpours to the northeastern U.S. and break the back of an extended heat wave.
Repeating and slow-moving storms will raise the risk of flash flooding and damaging winds over northern and central High Plains into Thursday night.
The F1 season continues this weekend with the German Grand Prix in Hockenheim with disruptive showers and thunderstorms in the forecast.
Highs will run between 10 and 15 degrees Fahrenheit above average across much of the western United States into the upcoming weekend.
Repeating downpours will raise the risk for flash flooding along the Gulf coast and lower Mississippi Valley through the middle days of the week.
The heat felt across the United Kingdom during the middle of July has faded and is not expected to return through at least the first week of August.
