2025-02-25 The ECMWF just issued first upgraded AIFS model version for its 6z cycle. https://www.stormvistawxmodels.com/sv/model/aifs We did not receive most recent runs in past 24 hours, so the change maps will be broken initially, unfortunately. Also, they have not specified a distribution schedule, but our understanding is that it should at least be 2-3 hours faster now that is operational and not experimental. You can read more about the upgrade here: https://confluence.ecmwf.int/display/FCST/Implementation+of+AIFS+Single+v1 New variables have been added for renewables (wind/solar), and we plan to add them to SV in the near future.
2025-02-24 New Model Cluster-Analogs are available on SV to take 11-15 day and day 15 clusters, find analogs for each, and then progress them into 16-20 and 16-30 day periods. See examples here: https://www.stormvistawxmodels.com/sv/model-cluster-analogs/ecmwf-eps/00z/usa/20250224/hanom?unit1=F&unit2=in&base-period=360&trel=No
2025-02-24 European Weekly Change HDD Comparison options now available to compare 24-hour, 48-hour, 72-hour, and 96-hour changes. See example here: https://www.stormvistawxmodels.com/sv/weekly-dd-changes/ecmwf-weekly/gw_hdd/2025022300z/p24
2025-02-14 PJM, ERCOT, CAISO, and MISO solar subregions added to SV website and API Examples here: https://www.stormvistawxmodels.com/sv/solargen/2025021406z/ercotgcentereast https://www.stormvistawxmodels.com/api#/paths/model-data-model---date---cycle-z-renewables--region--solargen-forecast.csv/get
2025-02-04 6z and 18z FourCastNetV2 ensemble cycles have been added for both initializations (GEFS, ECMWF).
2025-01-28 Starting Tuesday, February 4th, the PJM wind forecasts will be updated by removing PJM East and replacing it with South and Mid-Atlantic subregions instead. Sample API files will be sent to customers who pull these files.
2025-01-22 AI ensembles added to several existing ensemble analysis products on SV: Ensemble City Max/Min Statistics: https://www.stormvistawxmodels.com/sv/ensemble-stats/tmp2m/KORD/2025012212z/fcnv2-gfs-ens/imperial Ensemble City Contingency Threshold Tables: https://www.stormvistawxmodels.com/sv/ensemble-stats/tmin/KORD/2025012212z/fcnv2-gfs-ens/imperial Ensemble City Threshold Model Progression Tables: https://www.stormvistawxmodels.com/sv/ensemble-stats-dprogdt/tmin/KORD/2025012212z/fcnv2-gfs-ens/none/imperial

2025-01-16 A new climo drop down menu is available for departure/anomaly maps throughout StormVista to toggle between the NOAA standard 30-year normal (1991-2020) and the rolling 10-year normal (currently 2015-2024). Find them on the map panels and all the various composite and daily composite pages.
2025-01-16 Starting with today's 00z cycle, 6-hourly city extraction data is available via the API for the following AI models: aifs 00z, 06z, 12z, 18z out to F360 ai-fourcastnetv2-gfs-ens 00z out to F744, 12z out to F384 ai-fourcastnetv2-ecmwf-eps 00z out to F744, 12z out to F384 ai-graphcast-gdas-ecmwf-eps 00z, 06z, 12z, 18z out to F384 Please note that AI model offerings are more limited due to the finite number of variables they are trained with. Files for the AI models currently contain tmp2m, precip, tmp850, windspeed10, winddirection10, mslp, hgt500. More variables may be added as additional columns in the future as availability permits. Precip is not available for the ai-fourcastnetv2-gfs-ens or ai-fourcastnetv2-ecmwf-eps.
