Eastern half of U.S. braces for more long days of dangerous heat

Sunday marked the second straight day of extreme heat across the Midwest and East Coast.

Cities across the Midwest and eastern U.S. were preparing for another day of extremely high temperatures on Sunday as an unusual June heat wave persisted in the region.

By 7:30 a.m. on Sunday, the temperature had already reached 80 degrees Fahrenheit (26.6 degrees Celsius) in the Chicago area, as reported by the National Weather Service. Forecasts indicated that heat indices could range between 100 and 105 degrees F (37.7 to 40.5 degrees C).

In Pittsburgh, the heat index was projected to exceed 105 degrees F. Meanwhile, Columbus, Ohio, recorded a temperature of 77 degrees Fahrenheit (25 degrees Celsius) at 8:30 a.m., with expected highs of 97 degrees F (36 degrees C) and a heat index around 104 degrees F (40 degrees C).

Sunday marked the second straight day of extreme heat across the Midwest and East Coast. Heat indices on Saturday hit 103 degrees F (39.4 degrees C) in Chicago and 101 degrees F (38.3 degrees C) in Madison, Wisconsin, turning that city’s annual naked bike ride into a sticky and sweaty affair. Minneapolis baked under a heat index of 106 degrees F (41.1 degrees C).

The heat is expected to persist into the coming week, with the hottest temperatures shifting eastward. New York City is expected to see highs around 95 degrees F (35 degrees C) on Monday and Tuesday. Boston is on track for highs approaching 100 degrees Fahrenheit (37.7 degrees Celsius) on Tuesday, and temperatures in Washington, D.C., were expected to hit 100 degrees F on Tuesday and Wednesday.
