An additional 10-25 cm of snow is expected for the hardest hit areas, with intense snowfall rates of 2-4 cm per hour greatly impacting travel conditions through the day on Wednesday.

Temperatures will drastically fall as a strong cold front advances through, so icy surfaces are likely across the region, with a bitter wind chill kicking in, as well.

A strong low pressure system brought snow into northwestern Ontario on Tuesday, with it picking up in intensity across the northeast on Wednesday. By the time all is said and done, snowfall totals will top 10-20 cm for northwestern sections of the region, with as much as 40 cm in the northeast towards James Bay. This snow will be falling at a rapid rate through Wednesday, before gradually weakening into the evening hours.

"Visibility will suddenly be reduced to almost zero at times in heavy snow and blowing snow. Evaluate the possibility of delaying any non-essential travel until conditions improve," says Environment and Climate Change Canada in the winter storm warning posted for the northeast.

The wintry mix will include freezing rain and ice pellets through areas including, Sault Ste. Marie, Timmins and New Liskeard.

While intense, this blast of Arctic air will be brief, and will be followed by much milder weather during the weekend and early next week. Double-digit temperatures should reach all the way to Moosonee on Monday.

A strong cold front will then track across the region once again, and bring much colder temperatures from west to east by mid-week.
