Description
RexWeather is the most complete tornado and severe weather app on iOS. Whether you are chasing records, researching history, or watching the sky right now, everything you need is in one place.
HISTORICAL TORNADO DATABASE
Over 70 years of verified NOAA tornado records from 1950 to the present day, including current-year data from NOAA NCEI updated monthly. Search near any location with a customizable radius. Filter by date range and EF rating. Jump to famous outbreaks like the 2011 Super Outbreak with one tap. Tornado detail maps show real NOAA surveyed damage path polygons with per-segment EF intensity coloring when available, so you see exactly where each rating began and ended on the ground.
TORNADO POTENTIAL SCORE
A real-time 1-to-10 score showing how favorable atmospheric conditions are for tornado development at your location. It draws from active NWS warnings, NOAA SPC tornado probability outlooks, and GFS model data including CAPE, wind shear, 0-6km bulk shear, Lifted Index, and Convective Inhibition. Every factor is explained in plain language. When instability and shear are both elevated, the app warns you the atmosphere is loaded even before storms fire.
LIVE NWS SEVERE WEATHER ALERTS
Active National Weather Service alerts for your exact location appear on the home screen the moment they are issued. Purple for Particularly Dangerous Situation tornado warnings. Red for active tornado warnings. Amber for watches. Tap to read the full NWS text.
SPC CONVECTIVE OUTLOOKS
Day 1, Day 2, and Day 3 NOAA Storm Prediction Center outlook maps with categorical risk, tornado probability, wind, and hail layers. See your exact location risk and read the SPC forecaster discussion.
WEATHER AND MORE
Check weather and tornado risk for any city in the world, not just where you are. The app works fully offline with cached weather and tornado data when you need it. Customize your units, map style, and appearance. Canadian locations are fully supported with regional tornado potential scoring built in.

What's new (v1.4.1)
Version 1.4.1
The Tornado Potential score is significantly more accurate in this update.
The scoring engine now checks real-time storm spotter reports. If a tornado, funnel cloud, or wall cloud has been reported near your location in the last few hours, the score reflects that and a chip shows you exactly what was reported, how far away, and how long ago.
Rotation scoring has been upgraded. The app now reads pressure-level wind data from the GFS model to calculate Storm Relative Helicity, the same metric professional meteorologists use to assess tornado rotation potential. Previous versions used a rough approximation.
The Significant Tornado Parameter (STP) has been added. Rather than scoring each ingredient in isolation, STP checks whether all the key tornado ingredients are aligned at the same time. A strong STP means the atmosphere is truly loaded. A near-zero STP tells you the pieces are not coming together even if one or two individual values look elevated.
The score now adjusts for time of day. Tornado development peaks in the late afternoon and early evening. A Peak Window chip appears when you are in that window and contributes a point to the score.
Several bugs were also fixed. The rotation chip was frequently missing in previous builds due to a data decoding issue. It now appears reliably across all US locations. Switching locations no longer briefly shows the previous city's score while new data loads.
