Maryland officials said Sunday that 13 people have died from heat-related causes since July 2. The 11-day heat wave continued Sunday, as the temperature hit a record 104 degrees. National Weather Service officials said Sunday that relief is coming soon in the brutal heat, and temperatures are expected to fall by the end of the day. Strong storms neared the Washington area early Sunday evening, and there’s a severe-thunderstorm watch for the area through 10 p.m. Sunday night. The relief had already come to the Midwest—where temperatures last week had reached record highs—with Chicago residents enjoying 77-degree temperatures.
