About this app

Threshold is a precision weather intelligence app built for people who need to know what's actually happening with the weather — not just a number on a screen.

KNOW BEFORE IT ARRIVES
Threshold analyzes live NOAA MRMS radar data to detect precipitation approaching your location and sends you a push notification when rain is on the way. No manual checking. No vague forecasts. Just a clear alert when it matters.

SEVERE WEATHER MONITORING — ALWAYS ON
Threshold polls the Storm Prediction Center every 15 minutes and sends you a push notification the moment tornado, hail, or wind risk escalates — or clears — at your location. You'll know the second the outlook changes.

SHORT-RANGE FORECAST
See what's coming in the next 6-48 hours powered by NOAA's High-Resolution Rapid Refresh model. Temperature, precipitation, and wind at 3km resolution.

WHAT-IF ENSEMBLE FORECASTING
Most weather apps show you one forecast. Threshold shows you the range. The What-If tab analyzes 31 NOAA ensemble model runs to surface distinct forecast scenarios for days 3-5 and explains what conditions lead to each outcome.

BUILT ON REAL DATA
- MRMS — the same live radar mosaic used by the National Weather Service
- SPC Day 1 Outlook — official Storm Prediction Center severe weather probabilities
- NOAA HRRR — high-resolution short-range forecast model
- NOAA AIGEFS — 31-member AI ensemble for medium-range scenario analysis

CONDITIONS AT A GLANCE
Sky conditions, wind speed, and temperature highs and lows for today and tonight — always current, always cached for instant loading.

MULTIPLE LOCATIONS
Save home, work, and any other location. Switch between them instantly with pre-loaded weather data for each.

HIGH CONTRAST MODE
White background mode for maximum legibility in direct sunlight outdoors.

What’s new

Clearer current conditions and forecasts: the Now tab shows a real live station observation instead of forecast data, short-range forecasts show their true coverage window, and every card is labeled with its source so it's easier to tell what's happening now versus what's expected later.
