More Extreme Heat In Oklahoma's Forecast

Heat advisories are in effect across Oklahoma as another day of triple-digit heat grips the state.

The National Weather Service said more hot, dry weather is forecast after the state recorded afternoon temperatures on today as high as 109 degrees in Alva and Ardmore.

The high temperature in Oklahoma City reached 106, tying a record set 78 years earlier.

Forecasters said the state's weather pattern is expected to change toward cooler and wetter conditions late in the week as an upper low pressure system now over central Canada drops south. The front could arrive in Oklahoma as early as Wednesday.

Showers and thunderstorms are possible as early as Wednesday night and may last through the weekend.
