Strong westerly winds have ushering in much colder air and flurries in the wake of a sharp Arctic cold front that swept across Southern Ontario into Quebec and New York State yesterday.
While most areas will receive only a coating to perhaps a couple centimetres of fresh snow today, the strong winds will whip up the freshly fallen snow and result in local reduced visibility in blowing snow in exposed areas, especially in Southern Ontario and in parts of Eastern Ontario close to Lake Ontario.
Brief episodes of blowing snow are also possible later today in the rest of Eastern Ontario as gusty westerly winds develop.
Snow squall watches and warnings are in effect for the Southern Ontario snow belts to the southeast of Lake Huron and Georgian Bay.
Dangerous driving conditions are expected and travel into these regions is not recommended.
In this type of situation with strong winds, the lake effect snow bands may extend quite far inland at times, giving flurries and local blowing snow in many areas, and resulting in suddenly difficult driving conditions.
Motorists are urged to exercise caution and be prepared for sudden hazardous driving conditions from blowing snow and brief bursts of heavier flurries.
