Weather Underground Forecast for Tuesday, May 08, 2012. Active weather will remain in the eastern third of the country on Tuesday as a strong storm will move through the region. The associated cold front will drape itself from the Southern Plains through the Southeast and eastern seaboard. This front will produce scattered rain and thunderstorms throughout this region.
