Messy Weekend Storm Jan. 9-11, 2016


A few systems will come into play this weekend for parts of Eastern Canada and will make their way into Atlantic Canada at the start of next week.



As the main system comes in late Friday, I expect mainly snow for Central Ontario with mixing through Cottage country and rain for Southwestern Ontario. Some freezing rain / ice pellets will be possible at the onset of precipitation from Dufferin / Barrie, along and North of the Hwy. 7 corridor, and South of Algonquin. I would also like to point out the potential for some freezing drizzle over Southern parts of the Ottawa Valley at the end of Friday. 




Saturday should see rain across Southern Ontario with some mixing through the Nickel Belt and snow for Northern Ontario. Along the warm front through Southeastern Ontario and the ON/QB border some freezing rain is possible Saturday morning and early afternoon before changing to rain as temperatures continue to slowly rise.



By Sunday I am looking at rain gradually changing to a rain-snow mix and eventually transitioning to snow for most of Ontario and Southern Quebec as the cold arctic air filters South. Another period of lake-effect snow is possible on Monday, as snow squalls develop East of the Great Lakes. Atlantic Canada will see rain for the most part late Sunday into Monday. Parts of New Brunswick may see a brief occurrence of freezing rain / ice pellets late Sunday, before changing over to rain.
