2026-01-29	For the regional population-weighted HDDs for Russia, we need to remove Omsk, UNOO and are recalibrating the other station weights in response. These changes will take effect over the weekend. New normal and history will be available via the api this weekend too. Sorry for any inconvenience this may cause.
2026-01-28	New Spain and UK solar generation forecasts are added to website and api. See examples here: https://www.stormvistawxmodels.com/sv/solargen/2026012806z/uk https://www.stormvistawxmodels.com/api#/paths/model-data-model---date---cycle-z-renewables--region--solargen-forecast.csv/get
2026-01-27	SV histograms for city temperatures now include AI models and options to choose which models you want in the calculation (choose the Custom button to pick your models). https://www.stormvistawxmodels.com/sv/ensemble-histograms
2026-01-27	New snow and ice change maps (compared to prior cycle) now available on NOAA NBM model. Changes are very small frequently, but some cycles, like the 7z linked here, show bigger changes. https://www.stormvistawxmodels.com/sv/model/nbm/07z/ma/304-1-hr-snow-total-change Seems like the 1z, 7z, 13z, and 19z cycles show the most changes as new data are included.

2026-01-14	European weekly wind generation outlooks now available about 100 minutes faster on website and API (around 730am ET). https://www.stormvistawxmodels.com/sv/windgen-weekly
2026-01-07	Beta testing power/load forecasts on StormVista now has multilinear regression outputs for 15, 30, and 45-day periods. Website here: https://www.stormvistawxmodels.com/sv/power-load API here: https://www.stormvistawxmodels.com/api#/paths/model-data-model---date---cycle-z-power-load--reg--hourly-load-forecast.csv/get

2025-12-30	New AI Teleconnection Round Up Emails Available on StormVista. You can add it to your distribution here. This is similar to the regular model teleconnection roundup that is updated on the 0z and 12z cycles: https://www.stormvistawxmodels.com/sv/custom-email-builder/additional AI Teleconnection Round-up: 0z and 12z summary of AI teleconnection values and trends
2025-12-29	You can now share custom emails on StormVista with other users. https://www.stormvistawxmodels.com/sv/custom-email-builder/ A new button option called share code will allow you to send a code to colleague that they can import (import option at top of page). You can also click multiple emails and choose "bulk share code" to send more than one.
2025-12-18	Added Daily Verification page for Power/Load here: https://www.stormvistawxmodels.com/sv/power-load-daily-verification/ercot/00/5 The 30-day hourly verification is now updated as well: https://www.stormvistawxmodels.com/sv/power-load-verification/ercot/00/mae/30 We are continuing to work on this new feature. Thanks for your great feedback.
2025-12-17	German solar generation forecasts added to StormVista. See example here: https://www.stormvistawxmodels.com/sv/solargen/current-00z/germany And available on API here: https://www.stormvistawxmodels.com/api#/paths/model-data-model---date---cycle-z-renewables--region--solargen-forecast.csv/get Side note: this is based on weather model forecasts for available generation; they tend to do a lot of curtailment
2025-12-12	New page allows you to edit/update/delete custom SV regions created for on-demand composites, clustering, and analogs: https://www.stormvistawxmodels.com/sv/custom-regions Page is also found linked alongside where you save/make new custom regions on each page.
2025-12-11	48 and 72-hour change tabs now available on SV city forecast pages: https://www.stormvistawxmodels.com/sv/city-plots-max-min

Also note that the 0z cycles of the Euro and GEFS weeklies update late each day, so in most cases, you will need to pull the prior day's cycle.
2025-11-26	New Stratospheric U-Wind history page on StormVista now includes an analog calculator: https://www.stormvistawxmodels.com/sv/strato-tracker Scroll to bottom and pick the number of days to measure and the number of top correlated analogs to calculate.
