Snow/Rain for Ontario and Southern Quebec

February 26, 2009 — The system affecting Eastern Canada will be a weekend spoiler for many!

Northeastern Ontario has seen the bulk of the snow already but that does not mean conditions are going to improve just yet. Gusty winds are dominating the region behind the low pressure system and with so much freshly fallen snow on the ground, this means blowing snow. The winds will ease Saturday morning, but the cold weather is here to stay for the weekend!

The spring-like temperatures felt over Southern Ontario will be pushed out by a cold front. Temperatures will drop across the region, and with the wind, it will feel like the minus teens. Flash freeze is a big concern because the roads are still wet from the rain that has just fallen. Areas such as the Niagara Peninsula will see a transition of rain to snow starting this afternoon before the moisture tapers off. For the Ottawa Valley and the St. Lawrence Seaway, the transition will happen this evening. However, no major snow accumulations are expected.

By tonight, the cold front will push rain into the Maritimes. On Saturday, Halifax, Moncton and Charlottetown will wake up to rain. However, the rain will change to snow starting Saturday morning in Northeastern New Brunswick as the arctic air mass continues its way eastward. This changeover will occur later in the day for Southeastern New Brunswick, Nova Scotia and PEI.

The same cold front continues the journey to Newfoundland, bringing rain around Saturday morning on the west coast and reaching St. Johnís by Saturday night on the east coast. As the cold air drapes the island, the rain will switch over to snow around Saturday night in the west and sweeping towards the Avalon Peninsula by Sunday morning.
