With clear skies and not quite the breeze of yesterday, temperatures were expected to climb to about 100 degrees in Baltimore today.
And with 55 percent relative humidity, it could feel like as much as 110 degrees, said Ken Shaver, a National Weather Service forecaster at Baltimore-Washington International Airport.
"It looks like today is going to be the hottest of the week," Mr. Shaver said. It was 98 degrees at noon, the weather service said. The record high in the city for this date, set in 1954, is 101 degrees.
