Late winter storm with freezing rain Saturday night into Sunday morning then strong winds with snow and blowing snow Sunday night into Monday morning.
Precipitation associated with a strong low pressure system may begin as snow overnight Saturday night or early Sunday morning but is expected to quickly transition to freezing rain or ice pellets and then to rain by Sunday afternoon.
Surfaces such as highways, roads, walkways and parking lots may become icy and slippery.
The precipitation is then expected to change back to snow late Sunday afternoon or Sunday evening. The latest analysis suggests total snow and ice pellet accumulations in the 5 to 10 cm range by Monday morning.
In addition, strong winds will develop Sunday evening with gusts to 70 km/h possible Sunday night into Monday afternoon resulting in very poor visibility in blowing snow.
Visibility may be significantly and suddenly reduced to near zero making travel dangerous.
There is still some uncertainty regarding the track of this low pressure system originating in Texas. Environment Canada meteorologists will continue to monitor this developing situation closely.
