DETAILS
A Texas low will track northeast across Oklahoma to Illinois today then follow a path near the south shore of Lake Erie on Friday. Snow associated with a trough ahead of this system has spread into Southern Ontario from Michigan with a couple cm of light snow possible by this evening in a swath of regions extending from Lake Huron to Western Lake Ontario. This low will intensify into a major winter storm as it approaches Southern Ontario. An expanding area of heavy snow is expected to move into western parts of Southern Ontario near Lake Huron beginning this evening then spread east across remaining regions overnight. The heaviest snow will occur during the Friday morning rush hour along the highway 401 corridor from London to the Greater Toronto area to Kingston and through the Golden Horseshoe. The snow, quite heavy at times is expected to continue well into Friday as the Texas low storm centre passes just south of the Great Lakes. Strong and gusty northeasterly winds will also result in local blowing snow in many areas tonight and Friday. Many parts of Southern and Eastern Ontario will receive 15 cm to 25 cm of snow from this storm before it ends Friday night. Total snowfall amounts will be lower over areas to the north of Lake Erie due to warmer temperatures giving rain or wet snow at times. Please consult the special weather statement there for more details. Areas along the western shore of Lake Ontario will receive near 25 cm of snow due to some enhancement in the cold easterly flow off of Lake Ontario. Additionally these winds will result in blowing snow which may produce prolonged periods of very low visibilities. A winter storm warning is thus in effect for these regions. Travelling conditions will quickly become hazardous in the snow and blowing snow tonight and Friday. There will be a major impact on the commute to work on Friday morning and possibly Friday afternoon in heavy snow and blowing snow. Please refer to your local public forecast for further details.
