Snowy weekend


It amazes me some times just how influential the Great Lakes can be to our weather here in North Grenville. The picture above was taken around 8:20 this morning and shows a steady plume of snow in our area caused my a streamer off Lake Ontario. Theses bands of snow are occurring ahead of the main area of precipitation associated with an Alberta Clipper racing east. The bulk of the snow, 5-10cm, will fall tonight and Sunday. Roads will be snow covered and slippery this morning and again late tonight and Sunday. Plan your travels accordingly. The snow will affect mainly eastern Ontario this morning but the clipper system will provide the 5-10cm area wide including Montreal. In addition to the snow, strong gusty winds from the southwest and then northwest will lower visibilities on Sunday. Temperatures will plummet Sunday night to near -18C as the coldest air this season moves in.
