What this is

A weather forecast that tries to be right for reasons you can inspect. On your iPhone and in your browser.

Most weather apps pick a model and show you its output. Some average a few of them. WeatherMeld combines five independent forecast models using a methodology we've been building and validating against years of real observations. Disagreements are shown and produce a Meld Forecast. Leave the spaghetti on a plate.

Every forecast carries a Meld Score, 0 to 10, that says how much to trust it. It's built from named parts you can open and read, not a gut feeling dressed up as a number.

There is no AI in the forecast. The methodology is classical statistics, chosen because every step of it can be written down, checked, and explained.

Tap a number and you see the reasoning. Tap the reasoning and you see the underlying data. Most users will never do either, and that's fine. The answer on the first screen is the same either way.

Coverage

Continental US only. Alaska, Hawaii, and US territories aren't supported; the methodology isn't tuned for those regions, and serving them would mean serving them poorly.

Full CONUS from launch. Open the app in Nashville or Missoula or Green Bay and it works.

More than the forecast

Weather is more than just temperature and rain. The app carries the rest; one place for the whole picture and, for people whose plans live closer to the water, the snow, or the sky, layers that go deeper than others.

Those numbers aren't ours. Air quality comes from federal monitoring networks, tides from NOAA, and so on. Anything we pass through shows its issuer and issue time, is never blended into the forecast, and never becomes a number we made up ourselves. The same tap-to-inspect rule, applied to work that isn't ours.

What it won't do

WeatherMeld does not produce its own severe weather forecasts. Warnings for dangerous conditions come from the National Weather Service, passed through unaltered and clearly attributed. When lives are at stake, the answer should come from the people whose job that is; not from an app trying to differentiate itself.

Feels-like temperature

Feels-like is shown as a short qualitative banner: feels cooler, feels about right, feels much hotter; with safety flags at extremes. It isn't a specific number because it isn't one. Apparent temperature is a modeled estimate with real uncertainty; displaying it as 42°F implies a measurement precision that doesn't exist. Tap the banner to see the estimated range.

Free and paid

The free tier is a complete weather app, not a demo. The forecast is the real thing, the Meld Score is visible, and current safety information is never behind the paywall. No ads, no selling your data, no nagging you to upgrade. If it scratches your itch, use it forever: Free

The paid tier exists for people who want more; the reasoning behind every score, every model side by side, more places, deeper layers. It's expansion, not ransom. One subscription, one price, phone and web. Details closer to launch.
