Start with live guidance
Atmosight pulls provider forecast guidance, recent weather context, 15-minute nowcast data, nearby point samples, air quality, and official NWS context when it is available.

What Atmosight is
A decision engine wrapped around a weather forecast.
Your grandpa's weather app and The Weather Channel are optimized for a quick answer: current condition, hourly icons, and a daily high/low. Atmosight is optimized for the second-order questions that matter when weather affects a plan: what evidence supports this, where might it fail, how fast is it changing, and when should I check again?
Source-backed Locally post-processed Verification-aware Recheck-oriented
Run a local transformer pass
A deterministic transformer looks back over the last 96 hours, adjusts hourly temperature, precipitation, wind, confidence, and hazard signals, then exposes what it paid attention to.
Temper it with history
Historical residual buckets and nearest analog windows keep the model honest about where it tends to miss, how wide intervals should be, and which regimes are thinly tested.
Blend the near-term nowcast
The first six hours are corrected with source-backed 15-minute precipitation, temperature, snow, condition, and gust signals so the immediate runway can change quickly.
Compare against outside evidence
Atmosight cross-checks provider guidance, NWS hourly forecasts, current station observations, official discussions, neighborhood spread, and historical verification before calling a forecast settled.
Translate weather into action
The output becomes a decision readout, watchlist, bust-risk score, recheck cadence, planning windows, departure guidance, and a phone-ready brief instead of just icons and highs.
Not just a prettier forecast feed.
It treats uncertainty as the product
Lower, expected, and higher-impact paths, timing spreads, reliability scores, and lead-time error budgets stay visible when the forecast is not settled.
It asks whether the forecast can bust
Model drift, regime coverage, source consensus, observation disagreement, and neighborhood volatility are promoted before a pretty hourly chart can become false confidence.
It shows provenance and disagreement
Source freshness, official alerts, NWS forecast discussions, station checks, and model-vs-guidance deltas are part of the readout, not hidden in the machinery.
It learns from analogous misses
Backtests, analog replay, residual calibration, and pass/watch/fail quality gates connect today's forecast to the kinds of events where the model has helped or hurt.

Important boundaryAtmosight does not replace official warnings.
It keeps National Weather Service alerts and forecast discussions in the evidence layer, then uses the local model, analogs, and verification context to explain how much confidence to place in the next few hours and days.
