WHY OUR TEMPERATURES GOT SLOWER — AND WHY WE'RE FINE WITH IT

Our data provider ended its trial and quoted $1,200 a year for numbers the government publishes free. I said no — the dashboard now runs straight from the National Weather Service. Same stations, same readings; here's the one tradeoff, stated plainly.

WHAT HAPPENED

Since launch, this dashboard's live temperatures arrived via Synoptic Data, a company that republishes the ASOS station readings — the exact stations Kalshi settles on — within a couple of minutes. This week Synoptic told us the trial was over: API access would be $1,200 a year, $50 per station, on a sales contract. I declined. Good service, wrong economics for a small self-funded project renting back public data.

THE HONEST PART

Every temperature here has always been a public observation — published by the National Weather Service, feeding the same official climate reports these markets settle on. Synoptic never owned the data; they sold speed. So we rebuilt the feed to pull directly from NWS: same 24 settlement stations, same official readings, same accuracy.

The one real cost is the clock. NWS releases readings in batches, so our cards trail a station's newest print by roughly 25 minutes — during a fast climb, that can be a degree or two (Miami printed 86° this week while our card showed 84°). It's disclosed in a source line under the grid, and every city card opens the station's live official prints in one click. When you're trading into a peak, the prints are the ground truth — and they were never behind.

WHAT'S NEXT: PRO

A trader in the chats nailed it this week: "Use something to project — otherwise I may as well just use NWS and Gemini." Right. Readings are free for everyone; data was never the product. So the Pro tier in the works is an interpretation layer: a projected daily high for every station — the day's pace, the remaining heating window, the official forecast — shown next to the observed prints, with its projected-vs-actual track record kept public. The research fuel is Iowa State's IEM archive: decades of these stations' records — when each peaks, how it runs against its forecast.

No price, no date. Pro stays "Coming Soon" until it's genuinely worth paying for — and this blog will show its homework first.

Thanks to everyone in the market chats who caught the slow cards within the hour and said so. The site is more honest because of it.
