Winter’s first sign is about to appear in parts of New Brunswick.

A snowfall warning has been issued for northwestern regions, including Grand Falls, Edmundston and Campbellton.

Environment Canada says snow is expected to move in Sunday night and continue into Monday morning.

Forecasters are calling for between 20 and 25 centimetres of snow by the time it ends.

Meanwhile, warmer temperatures in southern New Brunswick mean that precipitation will fall as rain.

Between 10 and 15 millimetres are forecasted in places like Moncton, Sussex, Saint John, and Charlotte County.
