The Storm Prediction Center has outlined the Northeast and the Midwest severe chances for Tuesday. A cold front moving through the Midwest and Ohio Valley and eventually the Northeast will bring some much-needed relief from the hot and humid conditions, especially for the East Coast.  The threat of severe thunderstorms will exist all along the cold front as well.  Thunderstorms that reach severe limits Tuesday afternoon and evening will bring the risk of damaging wind gusts in excess of 60 mph. Closer to an area of low pressure, the state of Maine may also experience hail and an isolated tornado risk as thunderstorms rumble through the region on Tuesday. Thunderstorm coverage will be spotty in nature through the evening, with the potential for lingering thunderstorms after midnight in the lower Great Lakes region and lower Ohio Valley. Cities such as New York, Pittsburgh, and Richmond will hang onto the chance for showers and thunderstorms on Wednesday.  A few storms may reach severe limits.
