WeatherAI 2026.04.3: Severe Weather Hub, Redesigned SPC Outlooks, and Wildfire Perimeters
A new Severe Weather Hub for active threats, a rebuilt SPC convective outlook map, surface fronts on radar, wildfire perimeter polygons, and more.
What's New
WeatherAI 2026.04.3 introduces a brand new Severe Weather Hub, a redesigned SPC convective outlook map, surface fronts and pressure centers on radar, wildfire perimeter polygons, and several improvements across the app.
Here's everything in this release.
Severe Weather Hub (US only)
A new Severe Weather Hub brings everything you need during active severe weather into one dedicated place. The hub is organized into three sections:
- Near Me — Active threats near your location, recent storm reports, the SPC convective outlook timeline, and excessive rainfall risk
- National — National severe weather alerts and a nationwide storm reports map
- Preparedness — Educational content covering hazard types, what watches and warnings mean, and how to stay safe
You can open the hub from a new card on the Home Screen. If you'd prefer not to see it, the card can be hidden from Home Screen customization.
Redesigned SPC Outlook Map
The SPC convective outlook map has been rebuilt from the ground up. You'll notice:
- Cleaner rendering with sharper lines and legends
- Improved hatched-area visuals for significant tornado, wind, and hail risks
- More responsive day and product switching
Surface Fronts and Pressure Centers on Radar
Radar can now display the WPC national forecast chart — including surface fronts (cold, warm, stationary, occluded) and high/low pressure centers — directly over the map. It's a great way to see the synoptic picture alongside what's happening in real time.
Toggle it on from the radar layer settings.
Wildfire Perimeters
Active wildfire perimeters are now drawn directly on the wildfires map as shaded polygons, in addition to the existing point markers. This makes it easy to see the true footprint of large fires at a glance instead of relying on a single pin.
Improved WPC Rainfall and Winter Precipitation Views
The Excessive Rainfall and Winter Precipitation forecast views now share a unified legend with clearer risk levels and color coding. The map controls have also been tightened up for easier day switching.
Radar Alerts List Overhaul
The list of active alerts on the radar screen has been reworked with better grouping, richer alert details, and faster navigation between alerts — especially helpful during widespread severe weather events.
Bug Fixes and Improvements
- Smoother, more consistent detail views across earthquakes, METARs/TAFs, wildfires, storm reports, and weather alerts
- Improved local LLM responses for daily weather summaries
- Cleaner sharing footers and share cards across the app
- Fixed SPC categorical and probabilistic outlook color rendering for significant-risk areas
- Fixed several small issues across the severe weather and SPC views
- Various performance and memory improvements from behind-the-scenes code cleanup
