Minute-level airport weather intelligence
Airport sensors report every minute. METARs don't. Pro turns that minute-by-minute signal into a live nowcast of where the next METAR is heading — across 30+ airports worldwide: China's eight majors plus live beta coverage spanning Asia, Europe, the Middle East and the United States.

What you get
📡
Minute-by-minute runway temps
The same sensors behind the official METAR — sampled every minute, not every 30–60. Watch the trend form before the METAR prints.
🚦
Decision light
A live trust read: stable / changing / rapid regime × per-city data health. It tells you when the signal is solid — and when to sit out.
🎯
Next-METAR nowcast
A backtested estimate of the next METAR's rounded temperature — adjusted for known biases — with the regime and slope behind it.
📈
Today's-high tracking
The running daily-high METAR number per city, with the peak timestamp.
🛰️
Model forecast high (Pro)
Today's expected high from an ECMWF/GFS/ICON consensus — with the hour it peaks, afternoon cloud, and the per-model spread one click away. Context for the live nowcast, not a replacement.
📊
Day context — free
Every city also shows today vs yesterday, observed current conditions (wind, sky, visibility, pressure, dew point), a cloud-driven daily-high cap risk and a plain-language quick read.
🌏
30+ airports worldwide
Eight China majors plus live beta across Asia, Europe, the Middle East and 10 US cities — full list below.

Where the edge comes from
We didn't start with a paywall — we started with a question: can a short-term runway-temperature trend help forecast the next METAR? We built the model, backtested it across cities, and kept only what held up.
~77%
next-METAR hit rate
across 6 cities in backtest — about +15 points over the naive “same as the last reading” baseline.
⚠ Honest about what it is
It's a nowcast, not an oracle. It reads where the next 30–60 minutes are heading — it does not predict a market's daily-high outcome, and nothing here is betting advice. The decision light exists precisely to flag when the signal isn't trustworthy, and a per-city health monitor auto-disables a feed when it goes bad.

FAQ
What am I actually paying for?
Real-time decision signals (decision light, next-METAR nowcast, regime & hit-rate), a model forecast high (ECMWF/GFS/ICON consensus, peak time & cloud), full real-time runway data, and CSV export. The free tier still gives current conditions, today-vs-yesterday and a quick read — it just delays runway data by 10 minutes and locks the decision signals and model forecast.
I'm already on the $9.99 plan — will my price go up?
No. If you have a card subscription at $9.99/mo, you keep that rate for as long as it stays active — the $39.99 rate applies to new members only. (Crypto is pay-as-you-go with no auto-renewal, so each new purchase is at the current price.)
Is this betting or financial advice?
No. It's view-only data and decision support. You make your own calls — see the “view only” note on every city.
Can I cancel?
Yes, anytime, from your account. Billing is handled by Stripe via Clerk.
