| 2026-09-28 | New Atmospheric River Forecasting Tools are Available Integrated Water Vapor Transport maps are available on StormVista: https://www.stormvistawxmodels.com/sv/model-maps/model-ecmwf-suite/cycle-current/region-westernusa/image-388-integrated-water-vapor-transport And now, new difference maps (Euro minus GFS) are available: https://www.stormvistawxmodels.com/sv/model-maps/model-ecmwf-suite/cycle-current/region-westernusa/image-389-ecmwf-gfs-integrated-water-vapor-transport-difference | |
| 2026-09-10 | AI-WEATHERNEXT3 is now generally available through our API starting with the 00z cycle on 2026-09-10. Product suite matches ai-weathernext2, except for hourly data and bias corrected data which needs time to build. For exampke, see ai-weathernext3 WDD here. | |
| 2026-09-09 | With the retirement of the NAM nearing, we've expanded our HRRR and RRFS offerings to match, where possible, output from the NAM. | |
| 2026-09-09 | Tropical track density plots are now based on distance, instead of pixels, to provide a consistent experience across zoom levels. See on our Active Plotter and Genesis Plotter. | |
| 2026-09-09 | Significantly expanded WeatherNext3 graphics to match WeatherNext2; API data, coming soon. See WeatherNext3 images here and on various composite pages. | |
| 2026-09-04 | Initial Images for WeatherNext3 Now Available We have a first batch of maps now running: https://www.stormvistawxmodels.com/sv/model-maps/model-ai-weathernext3/cycle-00/region-na/image-29-500-mb-height-anomaly https://www.stormvistawxmodels.com/sv/model-maps/model-ai-weathernext3/cycle-00/region-na/image-30-2-m-temperature-anomaly https://www.stormvistawxmodels.com/sv/model-maps/model-ai-weathernext3/cycle-00/region-na/image-18-2-m-temperature Please see our front page article about the situation and new challenges with this model: https://www.stormvistawxmodels.com/googles-shiny-new-toy | |
