We had the warmer air the last few days associated with a low pressure system, now we cool down and the risk of snowsqualls for most of the day. March is definitely a weather roller coaster.

Snow squall warning in effect for: Sault Ste. Marie – Superior East Agawa – Lake Superior Park
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls are expected. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
Snow squalls have developed over the area and are expected to continue tonight. Snowfall accumulations of 15 cm per 12 hours are possible.
The snow squalls will weaken early Thursday morning.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Travel is expected to be hazardous due to reduced visibility in some locations. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop.
Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
