..Heavy snow and blowing snow threatening Saturday.. An area of light to moderate snow is currently affecting the area giving a few centimetres. The snow should taper off this evening before a more significant low pressure area from Texas brings significant amounts of snow starting overnight as it moves towards Southern Ontario. Snow amounts of 15 to 20 cm are likely with this storm. In addition strong northerly winds ushering in much colder air will also result in very low visibility in blowing snow in exposed areas. There is also a risk of freezing rain overnight. Conditions should improve by Saturday evening. Travelling conditions may become quite hazardous as a result on Saturday. People should be prepared to adjust travel plans as required.
