DALLAS (AP) _ The southern Plains sweltered through another day of triple-digit heat Monday, although cloudy skies and scattered showers brought relief to some areas.

North Texas endured its 29th consecutive day of temperatures above 100 degrees.

``Oh, Lord, I don't know how long it's been since it rained last,'' said Deidre Roberson, a motel clerk in Tyler, about 100 miles east of Dallas. ``It's been so long.''

Tyler got about 10 minutes of rain while parts of Fort Worth got heavy downpours, the first measurable rain in the area since July 5.

``The rain! It came!'' said Tony Panibiknci, interviewed by a TV crew while parked under a highway overpass to escape the rain.

However welcome, the showers didn't cool most areas. Record high temperatures were reported in Corpus Christi (99), College Station (106) and San Antonio (103).

Nationwide, at least 161 people have died from the heat, including 31 people in Louisiana, 19 in Oklahoma and seven in Alabama. The Texas heat-related death toll rose to 103 with the addition of four more deaths.

In Oklahoma, temperatures near the Red River border with Texas easily topped 100 degrees, but temperatures were mainly in the 80s and 90s over the rest of the state as clouds and a cool front helped bring change.

In California, temperatures soared into the triple digits and Southern California Edison asked millions of customers to conserve electricity.
