Snow squall warning in effect for:

  • Mount Forest - Arthur - Northern Wellington County

Snow squalls developing this morning.

In the wake of a sharp cold front, lake effect snow will develop this morning, intensifying into stronger snow squalls late this morning or this afternoon. The most intense snow squalls are likely this afternoon and evening.

Local snowfall accumulations near 20 cm will be possible under the most intense snow squalls by Wednesday morning. Gusty winds will accompany these snow squalls at times resulting in periods of blowing snow.

Winds will become southwesterly by Wednesday morning, shifting the snow squalls northward to mainly affect Bruce County and northern Grey County on Wednesday. Additional snowfall accumulations of 15 cm are expected in these regions on Wednesday.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel is expected to be hazardous due to reduced visibility. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop. Road closures are possible. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.
