Cold Arctic air has combined with moisture moving over the Rockies to give Alberta a taste of winter in late summer.
Forecasters say northern Alberta including Edmonton could receive at least 8 cm snow with up to 15 cm in Jasper.
Temperatures are hovering near or slightly below freezing with a plunge to -6 C in northern British Columbia.
Environment Canada says more seasonable weather is not expected to return until early next week.
It may have been the warmest summer in the Maritimes in almost a century but some parts of the region woke up to below freezing temperatures and frost this morning!
That means some areas had a growing season which barely lasted 100 days since the last spring frost for many was 04 June.
Greater Moncton was definitely chilly with an early morning low of 3.0 C which was close to the record low of 1.1 C from 1956.
Here are some of the nippy overnight lows:
- Edmundston, NB -2.0 C
- Woodstock, NB -0.8 C
- Red Pines, NB -0.7 C
- Fredericton, NB 0.1 C
- Upper Stewiacke, NS -0.4 C
- Maple Plains, PEI 1.4 C

Greater Moncton has endured the coolest June in recent memory and while daytime highs were close to normal – with a few exceptions – overnight lows were cold, even frosty at times during the first half of the month.
A hard frost on 04 June with a record breaking low of -3.2 C was devastating for agriculture across New Brunswick especially in the Southeast.
Farmers suffered major damage – in some cases 50 to 80 percent losses – to crops such as grapes, strawberries and blueberries.
Oddly enough, the temperature had not been that low in all of May and not since 16 April had it been at least that cold.
Rainfall was about 60 percent above normal and was confined to a handful of major rain events with nine days being completely dry.

When it snows in June it might as well be January which gives us a new month called Juneuary!
