Scorching temperatures, humidity making life miserable for millions from Midwest to Maine

A blistering heat wave stretching from the Midwest to the tip of Maine is leaving millions of people sweltering through the Juneteenth holiday. Many cities have issued heat warnings and several places canceled activities planned for the holiday commemorating the end of slavery in the United States. Some places closed cooling centers due to the holiday, forcing those who rely on them find other places to seek relief. The dangerous temperatures are expected to peak in the eastern Great Lakes and New England on Wednesday and Thursday, and in the Ohio Valley and Mid-Atlantic on Friday and Saturday.
