Lesser amounts are forecast over northern coastal sections and along the Strait of Belle Isle. On Sunday the snow will change to rain or freezing rain over southeastern sections as a strong warm southeasterly flow develops. Over Western Labrador a brisk flow combined with bitterly cold temperatures will cause extreme wind chills Sunday morning.
