Weather, in plain English

Weather data is public, taxpayer-funded, and genuinely readable once someone explains the vocabulary. Almost nobody does, because confused people are easier to sell subscriptions to. These guides fix that: how the instruments work, what every number means, how forecasts are made and where they fail, and what actually keeps you safe when the weather turns.

No signup. No paywall. No ads. Not ever. The same principle as the app. You already paid for this data, and understanding what's happening outside shouldn't cost anything. Read one, read all 27, send them to whoever needs them.

Six sections, twenty-seven guides. Open whichever one you need, or expand everything and read straight through.
