OKLAHOMA CITY (AP) — Forecasters say the heat wave gripping the central U.S. is “unrelenting” and sweaty residents shouldn’t expect any relief soon.

Heat advisories and warnings are in place in 17 states, from Texas to Michigan, as temperatures and humidity combine to make being outside uncomfortable for millions.

In Oklahoma City, forecasters expected another day of 100-degree heat Sunday, which would be the 27th day this year the city has reached 100 or above. The city’s record is 50 such days, set in 1980, and it’s on pace to break it this year.

National Weather Service forecaster Daryl Williams in Norman, Okla., says much of the central U.S. is under a so-called “heat dome” that isn’t moving much. He describes the heat as “unrelenting” and says the trend is for more hot weather.

DES MOINES, Iowa (AP) — A home invasion at Rep. Leonard Boswell’s Iowa farm ended when his 22-year-old grandson fetched a shotgun and aimed it at the intruder, according to a statement from the congressman’s office. No one was seriously injured.

The incident started about 10:45 p.m. Saturday when an armed man came in through the front door, attacked Boswell’s daughter, Cindy Brown, and demanded money, the statement said. Boswell, 77, heard his daughter’s screams, came into the entryway and attempted to disarm the intruder.

As they struggled, Boswell’s grandson, Mitchell Brown, got a shotgun from another room. When he pointed the shotgun at the intruder, the man fled into the fields around the house outside Lamoni.

Boswell’s wife, Dody Boswell, 75, also was home during the attack. His spokesman Grant Woodard said the whole family is safe and unhurt, aside from some scrapes and bruises.

The family is shaken up, but “they’re dealing with it pretty well,” Woodard said Sunday morning.

He deferred other questions to the Decatur County Sheriff’s Office, which is investigating along with the FBI and other agencies. Sheriff Herbert Muir wasn’t available for comment Sunday morning.

Boswell, a Democrat, has represented Iowa’s 3rd District for eight terms in Congress. He is expected to face a challenge next year from Republican Rep. Tom Latham, who is moving into the district to avoid running against Republican Rep. Steve King after their territories were merged during once-per-decade redistricting that follows each census.

Iowa is going from five to four congressional seats because its population growth hasn’t kept pace with the rest of the nation. The new 3rd District will include Des Moines and 16 counties in southwest Iowa.

Day tours of the famous Villisca Ax Murder House will not be held this week, so that the staff, family and friends of the museum’s operator can mourn his death. Darwin Linn owned the house where eight people were killed on June 10^th, 1912. Linn died Friday. He’d purchased the home in 1994 and restored the building to its near original condition in 1912.

Joshua B. Moore, his wife Sarah, and their four children lived in the home nearly a century ago. The family and two neighbor girls who were staying with them were found bludgeoned to death with an ax. To this day, their deaths remain unresolved.

Darwin Linn also operated the Olson-Linn Museum in downtown, Villisca, which features pictures and artifacts about the town’s history. He offered tours of the museum and the Ax Murder House, which was added to the National Register of Historic Places, in 1998. He eventually opened the house to overnight stays.

A woman and child riding on a personal watercraft were injured Friday evening, when their vessel was hit by another PWC on Carter Lake. Authorities say a 5-year old boy and a 42-year old woman were struck as they were on the craft, at around 5-p.m.

A private boat brought the victims to the shore. The woman and child were then transported to the Nebraska Medical Center, where they were being treated for what were believed to be non-life threatening injuries.

No other injuries were reported, and additional details about the accident are not yet available.
