Can you feel the eerie chill in the air? It's not just because Halloween is a mere 24 hours away. The wicked witch that is Mother Nature is casting a chilling spell over Ontario, wrapping us in cold temperatures and ghostly snow.
Come Halloween morning, some regions might find so much snow that it'll take more than a mere broomstick to clear those tombstones. Lake effect snow around Lake Superior, Huron, and Georgian Bay might pile up a ghastly 5-15cm by daybreak. The Sault Ste Marie area might even see a haunting 25cm!
As noon approaches, the snow will retreat into the shadows. Expect temperatures to peak in the low single digits in Southern Ontario and plunge a few degrees below freezing in the North.
But don't be fooled! The lake effect snow bands will rise again, zombie-like, by late afternoon, driven by a southwesterly flow. This could ensnare the Grey-Bruce and Parry Sound regions in heavy wet snow and blinding conditions by dusk.
Late in the evening, the winds will change course, pushing snow bands from Lake Huron and Georgian Bay southwards. There might be a sudden, frightful burst of snow between 9 PM - 2 AM in Simcoe County, Exeter, and the Grand Bend area.
Some accumulation is possible overnight into Wednesday in Grand Bend, Meaford, and Collingwood. We'll have more on that in an upcoming forecast!

If any ghosts and goblins are venturing out for treats, they'll face bone-chilling temperatures across Ontario.
Early evening temperatures will range from -5°C in the northwest to 5°C around Lake Erie and the Niagara region. In Southwestern Ontario and the GTA, temperatures will hover just above freezing.
It'll be equally bone-chilling further north in Central and Eastern Ontario, with temperatures near freezing. Higher elevations in Central Ontario and throughout Northern Ontario will see below-freezing temperatures.
Northwestern Ontario might even experience -5°C, the night's coldest spot.
From the Instant Weather team, we wish you a thrilling (yet safe) Halloween! Bundle up and keep cozy!
