2022-09-21 Correction: New Nova Scotia Fiona floater did not update in time for start of European ensemble, but managed to get most maps of that cycle and will be all maps of future global model cycles. You can find the map projection under the Global option.
2022-09-21 Nova Scotia Fiona Floater added starting with current 12z European ensemble: We're working to get it into the menu system, but you can toggle to other models from there as they update going forward.

2022-09-08 Fire overlay options are now added to U.S. state maps for the HRRR model. These active fire locations are updated each hour.
2022-09-08 New vertically-integrated smoke maps now available for HRRR model. See example here:
2022-08-24 You can now choose to reverse the color bar on SV cloud cover maps (making clouds white vs. dark). To change that, go to My Account, Display Options, and change the menu option under Default Cloud Cover Colorbar. Make sure to hit Save at bottom of page.

2022-07-14 Wind generation forecasts added for four main cycles of HRRR model (0z, 6z, 12z, 18z) as compared here: Wind generation API data starts with HRRR model on today's 12z cycle (and then all of the four main cycles each day) as described here:
2022-07-12 Precipitable Water Anomaly maps are now available on StormVista for GFS, GFS-ENS, NAM, NAM-HIRES, and HRRR models (under precip and severe tabs). See example here:
