Analyses

Understanding current conditions is the starting point, and the most critical part, of any weather forecast.

Hundreds of weather stations, ships, and aircraft across Canada, the US, and the rest of the world report readings of temperature, pressure, wind, moisture and precipitation. These reports are received at the CMC, and used to improve our picture of the current state of the atmosphere. The analyses made available four times daily on this page provide the latest snapshots of the state of the atmosphere over Canada and the Northern Hemisphere.
