Temperatures across Ontario range from –22 °C in the northwest to –1 °C along the lower Great Lakes this morning, with a sharp cold front draped from Hudson Bay to Lake Erie. The live conditions above show the province split: a band of lake-effect snow off Lake Huron and Georgian Bay, and mostly clear skies east of Kingston.
What do the colours on the Ontario weather map mean?
The ontario weather map satellite layer uses infrared and visible imagery to show cloud cover — white/grey indicates thick cloud, dark blue or black means clear skies. The radar overlay, which provides ontario weather radar 24 hours loop, uses green for light precipitation, yellow/orange for moderate rain or snow, and red for heavy rates (5+ mm/hr liquid equivalent). A canada weather map live view combines both, letting you track the cold front’s eastward speed of roughly 40 km/h.
Where are the active weather warnings in Ontario today?
The ontario weather warnings today map highlights snowfall warnings from Sault Ste. Marie to North Bay (15–25 cm expected by evening) and extreme‑cold warnings in the northwest, where wind chill values drop below –40. A freezing‑drizzle advisory is posted for the Niagara corridor. For the full list, check the Weather Warning page.
How often is the Ontario weather map updated?
Environment Canada refreshes the radar composite every 10 minutes; the ontario weather map live view on this page updates automatically. Satellite imagery is typically 15–30 minutes old due to orbital pass times.
What’s the difference between radar and satellite on the map?
Radar measures precipitation hitting the ground (rain, snow, hail) in real time. Satellite shows cloud tops from space — useful for seeing the full extent of a storm system before precipitation reaches the surface.
