WeatherAI 2026.02.1: HRRR Forecasts on Radar, UK Alerts, and Himawari-9

What's New

WeatherAI 2026.02.1 is a feature-packed release that brings HRRR forecast model data to the radar map, weather alerts for UK users, Himawari-9 satellite imagery, expanded space weather tools, new MRMS layers, and improvements across the board.

Here's everything in this release.

HRRR on Radar (Beta)

This is a big one. Pro users can now view HRRR (High-Resolution Rapid Refresh) model data directly on the radar map. This brings forecast model visualization right alongside your existing radar layers, letting you see what conditions are expected in the hours ahead.

Available HRRR layers include:

• Precipitation — Forecast precipitation coverage
• Precipitation Rate — Expected rainfall intensity
• Precipitation Type — Rain, snow, sleet, or freezing rain
• Accumulated Precipitation — Total expected accumulation
• Temperature — Surface temperature forecasts
• Wind Speed — Forecast wind speeds
• CAPE — Convective Available Potential Energy for storm potential

You can view forecasts out to 48 hours for some model runs and up to 18 hours for others, depending on the run time selected. Tap the run time label above the radar slider to switch between different model runs.

This imagery is generated by WeatherAI using HRRR model data and updates every hour. This is a beta feature undergoing constant improvements — please reach out with any feedback.

UK Weather Alerts

UK users can now receive weather alerts from the Met Office. These alerts integrate fully into WeatherAI:

• Push notifications when alerts are issued for your area (if notifications are enabled)
• Home screen display when you're in an affected area
• Radar overlay showing alert boundaries (enable in radar settings)

If you're in the UK and run into any issues or have feedback, please let us know through Settings → Send Feedback.

RTMA Observed Conditions Card

For US users, a new Home screen card displays the last observed conditions from RTMA (Real-Time Mesoscale Analysis) data. RTMA typically updates every hour and provides a more accurate representation of recent conditions compared to other data sources that may have longer update intervals.

The card also includes charts showing how various conditions have changed over the past 48 hours.

Himawari-9 Satellite Imagery

Satellite imagery now includes Himawari-9, Japan's geostationary weather satellite. This provides high-resolution coverage of the Asia-Pacific region, including Japan, Australia, and surrounding areas — a significant expansion of our satellite capabilities beyond the Americas.

Space Weather Updates

Space weather gets several notable additions:

• Updated Kp source — Current planetary Kp and storm levels now use a more up-to-date data source for improved accuracy
• CCOR-1 Diff visualization — The newly released CCOR-1 Diff imagery from the Space Weather Prediction Center is now available
• Solar wind charts — New solar wind speed and density charts for monitoring space weather conditions
• Aurora visibility card — See the likelihood of auroras at your location based on current space weather and local weather conditions
• Sharing — Easily share space weather data via a share button at the bottom of most cards

Home Screen Insights Card

A new Insights card on the Home screen provides context-aware weather guidance based on current conditions. For example, when the feels-like temperature is high, the card explains why and offers tips for staying cool. The card adapts to different weather situations and will continue to evolve, especially as you configure your Interests & Preferences in the Settings tab.

You can reorder or remove this card like any other Home screen section.

Sunrise and Sunset Notifications

Never miss a beautiful sunrise or sunset again. You can now enable sunrise and sunset notifications in the app settings to receive alerts at the right moment. Requires a Standard subscription.

USGS Earthquake Updates

Earthquake details get a significant upgrade when using the USGS data source:

• ShakeMap data — View shaking intensity and impact areas for earthquakes
• Fault line data — Detailed earthquake fault lines are now available across the US
• Earthquake Insights card — Additional context about what might be expected based on the intensity and location of an earthquake

More MRMS Layers

MRMS gets a major expansion with eleven new layers, offering comprehensive analysis across the US:

• Vertically Integrated Liquid (VIL)
• VIL Density
• Probability of Severe Hail
• Azimuthal Shear (3–6 km AGL)
• Low-Level Rotation Track (2hr)
• Mid-Level Rotation Track (2hr)
• Precipitation Type
• Echo Top (50 dBZ)
• 3-Hour Precipitation
• 48-Hour Precipitation
• 72-Hour Precipitation

Combined with existing MRMS layers, WeatherAI now offers one of the most complete MRMS product suites available on mobile.

Bug Fixes and Improvements

• Fixed an issue where radar could return to your location automatically even with "Remember map position" enabled
• Fixed detailed red flag warnings causing performance issues on the Radar screen
• NWS home view and details now show observations from another station when the nearest station's data is stale
• Continued UI polish and visual design improvements
• Backend improvements for scalability, reliability, and performance

Get the Update

WeatherAI 2026.02.1 is available now on the App Store for iPhone, iPad, and Vision Pro. If you have automatic updates enabled, you may already have it.
