For those who are longing for summer, be careful what you wish for.
The season's first heat wave has much of the East Coast sweating, with temperatures expected to top 90 degrees in many places, including the nation's capitol.
Unseasonably hot temperatures set records in at least a dozen cities.
"We had 90 degrees in Chicago. We had 96 degrees in Washington, D.C.," Accuweather meteorologist Jim Dickey said. "It climbed to 94 in Raleigh, which tied a record all the way back from 1953."
Monday, Baltimore, Md., hit a scorching 98 degrees. Schools in the city are now operating on a half-day schedule because of the weather.
While many flocked to beaches to soak up the rays over the holiday weekend, the blazing temperatures are being blamed for a number health-related incidents.
In Washinton, D.C., more than 20 members of an Ohio marching band were treated for heat exhaustion and dehydration during the Memorial Day parade.
Police shut a beach down near Chicago after four people suffering from exhaustion were rushed to a nearby hospital.
"We just heard a lot of ruckus," one witness recalled. "It was like a riot and everybody was just everywhere. Then the police came and they shut it down."
Hot temperatures have also reached Philadelphia, Pa.
"I just stay hydrated, keep my Vitamin Water, eat light, and stay hydrated," one resident said.
Forecasters have issued heat advisories for Virginia and Maryland. The heat index in those states is expected to top 100 degrees.
