If you slept a little late this Sunday morning then you missed our brief return to winter overnight. A frontal boundary slipped across the St. Lawrence Valley with several hours of snow showers in both Montreal and Kemptville. Some areas received as much as 1-2cm with roads becoming slick in places. It has since cleared and the spring sun is shining brightly again. It will be a colder 24 hours ahead of us then yesterday with temperatures struggling to reach 3C today and dropping off to as cold as -12 tonight.

Big changes are underway for Manitoba and Saskatchewan and this may, and I say may set the stage for a late winter storm here in the east towards the end of the month. Portions of Manitoba and the Dakotas are preparing for heavy snow and blizzard conditions by late Monday with wind and arctic cold in Saskatchewan. This will be thanks to low pressure moving from Colorado to northwest Ontario. Heavy rain and thunderstorms will change to snow by late Monday with conditions deteriorating quickly by days end. It will snow well into Tuesday with very strong winds and impossible travel conditions in that area.

Here in the east this week will be just as calm as last week with no major systems in sight.
