After a visit to the doctor at the Heartland Medical Clinic, 1 Riverfront Plaza, 48-year-old Marsha Brown wheeled all of her belongings in a cart Wednesday afternoon along Seventh Street.

The diabetic who says she experiences frequent seizures was looking for some air conditioning and headed toward the Lawrence Senior Center, 745 Vt. After a recent bad luck streak, Brown has spent nights during the past month at shelters in the city and trying to find shade during the day.

“Yesterday I ended up passing out,” she said.

Brown was among the many Lawrence residents seeking respite from the 107-degree heat Wednesday afternoon.

High temperatures forced organizers to cancel the Lawrence City Band’s Grand Finale concert Wednesday evening at South Park. The city will announce possible rescheduling later.

And forecasters predicted triple-digit temperatures again today, with the National Weather Service extending its heat advisory until 7 p.m. Matt Sayers, 6News meteorologist, predicted some relief Friday with temperatures in the high 80s and a chance of rain.

Joe Mauler, a construction worker with B.A. Green, shades himself from the sun with a wet towel Wednesday as Chris Ousdahl finishes a brick wall at the entrance to Kansas University. With virtually no breeze for relief, the workers braved 107-degree temperatures as they hurried to complete the Docking Family Gateway near 13th Street and Jayhawk Boulevard.

Meanwhile, there are some public refuges from the heat. The Community Building, 115 W. 11th St., and the Holcom Park Recreation Center, 2700 W. 27th St., open at 7 a.m. The East Lawrence Recreation Center, 1245 E. 15th St., opens at 8 a.m.

The Outdoor Aquatic Center, 727 Ky., and the Indoor Aquatic Center, 4706 Overland Drive, open at 1 p.m., and the South Park Wading Pool, 1131 Mass., will be open from 1:30 p.m. to 7 p.m.

Lawrence Memorial Hospital has only reported one emergency room patient suffering a heat-related ailment, which was during the weekend. The patient was treated and released, said Janice Early-Weas, a hospital spokeswoman.

Several Lawrence charities have requests for house fans. Donors with spare fans can deliver them during the day to the Salvation Army, 946 N.H., the Ballard Community Center, 708 Elm St., or Penn House, 1034 Pa.

Chris Stewart, the city’s acting utilities director, said residents were using about 23 million gallons of water per day last week – normal for the summer. Last week’s rainfall had caused usage to decrease, he said.

After Westar Energy customers in Kansas burned a one-day record of 4,893 megawatts of electricity on Monday, they used a little less on Tuesday: 4,855 megawatts, Westar spokeswoman Karla Olsen said.

The heat wave has kept air conditioner repairmen busy.

“We’ve been extremely swamped. Everybody waits until the last minute,” said Ronnie Homer, service manager for Cloud Heating and Air Conditioning Inc. in Lawrence.

Homer said residents should make sure their air-conditioning filters are clean and use a garden hose to spray down and clear off the coil on their units.

Wednesday, case managers with Bert Nash Community Mental Health Center were handing out bottled water to homeless people as part of an outreach program funded by a city grant, said Scott McMichael, a Bert Nash spokesman.
