AccuWeather reported that the Northeast and mid-Atlantic will experience above-normal temperatures this summer, marking a noticeable difference from the cooler-than-average summer of 2014.

"I'm not expecting extreme heat, but periods of warmer-than-normal temperatures will come and go during the course of the summer," AccuWeather.com Expert Long-Range Forecaster Paul Pastelok said.

After a cooler-than-normal summer of 2014, the East overall is forecast to be hit by more 90-plus degree days this summer.

In Philadelphia and New York City, there may be as many as 10 more than last summer.

For much of the summer, the central and southern mid-Atlantic will come alive with showers and thunderstorms.

Washington, D.C., Baltimore and Philadelphia will be in the line of fire.
