   Mount Forest - Arthur - Northern Wellington County, Ont. (046410)

Current details:
Multi-day lake effect snow squall event beginning Thursday night.

Hazards:
Locally heavy snowfall with accumulations possibly exceeding 20 cm by Friday night.
Significantly reduced visibility at times in heavy snow and blowing snow.
Additional locally heavy snowfall through the weekend and into early next week.

Timing:
Beginning Thursday night and continuing through the weekend.

Discussion:
Lake effect snow off Lake Huron is forecast to develop Thursday night and will persist through the weekend and into early next week.

As is common with lake effect snow, snowfall amounts will be highly variable. Some areas may receive well in excess of 50 cm by the end of the weekend.

Road closures are possible this weekend especially over areas that receive multiple snow squall bands.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel may be hazardous due to sudden changes in the weather.

Consider postponing non-essential travel until conditions improve.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to [email protected] or tweet reports using #ONStorm.
