Why SevereWX

Not another weather app

Apple Weather and the rest read one model and show you a rain icon at 3 PM. SevereWX reads the latest high-resolution model runs for your coordinates, the Storm Prediction Center outlook, and your local NWS forecasters' discussion, then tells you whether that storm can produce hail, damaging wind, or a tornado, and how sure the models are.

Your location, exactly

Not the county. Not the metro area. The threat level for your specific coordinates — updated every time new model data arrives.

The data meteorologists use

HRRR and GFS model data, SPC categorical outlooks, NWS forecast discussions, and NadoCast ML tornado probabilities — synthesized into plain language.

7-day extended outlook

Days 4–7 use extended GFS runs and ECMWF IFS cross-checks, cross-referenced against SPC Day 4–8 probabilistic outlooks. Lower confidence than Day 1–3, but useful for planning ahead.

AI analysis, SPC authority

Our AI analyzes the data and explains what it means for your area. SPC outlooks are treated as authoritative — the AI never downgrades them.

What does "WX" mean?

WX is meteorologist shorthand for "weather" — a two-letter brevity code from Morse telegraph operators, standardized in the late 1800s and still used in NWS forecasts, aviation METARs, and storm spotter reports today.

Threat alerts in your inbox

When a Slight risk or higher is forecast for your location, you get an email before the storms arrive — not after the tornado warning is already issued.
