The system moving through the States which has had a special weather statement issued for all of Southern Ontario previously has now forced that to be upgraded to a Winter Storm Watch for large areas including Hamilton, Burlington, Oakville, Guelph, and the GTA.
The concern is over the potential for large amounts of precipitation which could include snow, ice pellets, and freezing rain. The Winter Storm Watch reads;
Winter storm with a combination of 15 to 20 cm snow and ice pellets, possible freezing rain, and strong winds expected Tuesday and Tuesday night.
Snow will begin early Tuesday morning. Snow will mix with or change to ice pellets later Tuesday. Strong easterly winds gusting to 80 km/h will cause reduced visibility in blowing snow. Total snowfall and ice pellet amounts of 15 to 25 cm are possible before ending Wednesday. There is also a risk of freezing rain.
Localized power outages possible.
This weather is associated with a Colorado low that will cross Southern Ontario Tuesday and Wednesday.
Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Poor weather conditions may contribute to transportation delays. There may be a significant impact on rush hour traffic in urban areas.
There is also still a Special Weather Statement in effect for Brantford, Kitchener-Waterloo, St. Catharines, and Niagara Region.
Several hours of freezing rain Tuesday.
Precipitation will begin as snow overnight. Snow will change briefly to ice pellets, with 4 to 8 cm accumulation, before changing to freezing rain. Freezing rain will continue for several hours before changing to rain Tuesday afternoon. Travel is likely to be affected.
Additionally, strong easterly winds gusting up to 70 km/h are expected Tuesday.
This freezing rain is associated with a Colorado low that will cross Southern Ontario Tuesday and Wednesday.
Freezing rain warnings are likely required as this event draws closer.
If this forecast weather does come in it will make travel on Tuesday difficult at best, dangerous at worst, it is recommended that if you can reschedule any planned trips that you do so. Otherwise keep an eye out for updates which will make their way to this place, our twitter feed, and our Facebook page as well as on air.
