Weather with the context missing from every forecast: what's unusual today, what changed overnight, why — in the forecaster's own words — and how it compares to decades of records. Any US location.

Every weather tool can tell Claude it'll be 85° with a 40% chance of rain. Anecast answers the questions that actually matter: What's unusual? Today's forecast against the nearest long-record station's normals and records — "8° above average, two shy of the 1987 record" instead of just a number. What changed? Anecast snapshots forecasts several times a day, so it can show the diff: "Saturday's rain chance jumped from 20% to 60% overnight." No other weather source remembers what the forecast said yesterday. Why? The National Weather Service forecaster's own discussion for your exact area — the mechanism, the uncertainty, what they're watching — not a generated guess. What's the record? Averages and extremes for today's date, with the years they were set, from stations with up to a century of history. Plus the forecast itself: live conditions, five days out, and the active watches and warnings generic tools omit. (In testing during Hurricane Isaias, a generic weather tool described landfall day as "85% chance of rain." Anecast returned the Hurricane Watch.) Works for any US point, honestly: major cities carry full history and daily editorial notes; anywhere else gets live forecast, alerts, and forecaster reasoning immediately — and asking about a place starts its change-tracking, so coverage deepens exactly where people are curious. Every response says which it's giving you. All data is primary-source NOAA / National Weather Service. All tools are read-only. No account, no setup.
