PHILADELPHIA – The heat that blanketed much of the U.S. began to ease up from unbearable to merely very hot Sunday as temperatures from the Midwest to the East Coast dropped from highs above 100 degrees down to the 90s.

Cooler air swept southward in the eastern half of the country, bringing down some temperatures by 15 or more degrees from Saturday’s highs, which topped 100 in some cities.

The heat of the past several days has been blamed for at least 35 deaths across the U.S, including the death of a 4-month-old girl and a 16-month-old girl that was hospitalized in suburban Indianapolis after both were found trapped in cars during 105-degree heat Saturday.
