Brief, intense snowfall is expected to develop. Under the snow squall, visibilities will be significantly reduced due to the heavy snow.

A cold front near Kapuskasing will continue to move southeastward this morning and snow squalls with low visibilities are possible along the front.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
