A record-breaking heat wave is intensifying across much of the central and eastern U.S., pushing temperatures to what officials are calling "dangerous" levels. More than 200 million Americans were under alerts on Tuesday for extreme heat. Temperatures felt well above 100 degrees across much of the Midwest. And soon, that same sweltering heat will peak in places like New York. As we look ahead to the July 4 weekend, forecasters say that, starting Wednesday, it's going to get worse before it gets better for large portions of the Midwest, including Chicago, Cleveland and Detroit. The "heat dome," as it's known, shifts east by the end of the week, threatening record temperatures across New York, much of the Mid-Atlantic and even New England.
