Thunderstorms are expected to develop in the western region of Arkansas during the afternoon and evening hours Monday, and bring showers and thunderstorms to other parts of the state throughout Tuesday, the National Weather Service said.

Meteorologist John Robinson said rain chances in northwest Arkansas should subside Tuesday evening, and are expected to decrease Wednesday afternoon in the southeast corner of the state. Chances of severe weather are not substantial.

Rainfall totals are expected to range from 3/4-inch in the northern half to the state to more than 2 inches in the souther half. Robinson said totals from southwest to central Arkansas could reach 3 to 4 inches due to high level moisture from Pacific Tropical Storm Octave.
