LITTLE ROCK, Ark. (AP) - Another day of extreme temperatures is expected in Arkansas on Saturday, but some relief could be on the way.

The National Weather Service has issued a heat advisory for 50 counties in the state. Faulkner, Benton, Crawford, Franklin, Pulaski, Sebastian and Washington counties are included in the advisory.

Forecasters say temperatures will approach and could exceed 100 degrees on Saturday. That could make people who work or spend an extended amount of time outside more susceptible to heat-related illnesses.

The weather service says a frontal boundary approaching from the north may provide some relief Saturday night, Sunday and Monday.
