Where the models disagree
temperature and rain, judged separatelyThe models often agree on temperature and still split on rain — and rain is usually what decides whether a plan survives. A wide rain range means the shower is genuinely uncertain, not that the forecast is wrong.
Common questions
Will it rain tomorrow?
At least one model puts the chance of rain as high as 43% tomorrow. When the models disagree on rain the shower is genuinely uncertain, which is exactly what a single blended percentage hides from you.
How accurate is a one-day forecast?
A one-day-ahead forecast is the most reliable one you will get — in our own testing, temperature error at 24 hours is well under half what it is at seven days. That is why tomorrow's forecast is worth trusting when the models agree, and worth questioning when they do not.
