2021-09-16	New total QPF city forecasts are now available via the Spaghetti plots on StormVista. Find them under Features --> City/Region Plots --> Spaghetti Plots and choose Total QPF under the Variable option. You can toggle on ensemble members in the legend as well. https://www.stormvistawxmodels.com/sv/city-plots/pcptot/KIAH/2021091612z/ These data are updating with the 9/16 12z cycle going forward.
2021-09-14	ERCOT and other ISO forecast comparisons are now available via the same-cycle compare menu options (to see how the official ERCOT outlook has changed over multiple days) and prior year ERCOT actuals are now a new line addition option. Find these two new features under the SV menu via Features --> Renewables --> Wind Generation or by going here: https://www.stormvistawxmodels.com/sv/windgen/2021091412z/ercot
2021-09-13	New feature on SV found under Features --> Tropical Models allows you to track ensemble member storm positions more easily from hour to hour as well as see how the model has changed from cycle to cycle. https://www.stormvistawxmodels.com/sv/tropical-buckshot/
2021-09-02	On single image pages, we've organized overlays into groups for easier access. We've also added the ability to use multiple overlays at a time and the ability to color an overlay. See 'Overlay' button here as an example.
2021-08-31	The European parallel guidance (the future upgraded model) is now becoming available and will be showing up on StormVista over the next few weeks before the October 12th official upgrade. Please note that these runs will usually be slower than the main versions with varying delivery times. Receiving the automated composite emails will help alert you to their availability (find that under My Account upper right of page). Please also note that the higher resolution data are not available, so we cannot calculate degree days yet. You can see all the maps though and the composites compared on the composite SV pages. Maps will be available under the Medium range menu on SV under the respective ECMWF and ECMWF ensemble options.
2021-08-23	Under Features --> Model Metrics you can now find two expanded coverage grid-correction pages for American/European operational/ensemble models. Choosing by Day # allows you to go back through 15 days of models to see how different forecast days verified. Choosing by Valid Date allows you to pick one date (like yesterday) and see how models performed over the past 15 days for that date (or pick earlier anchored dates too).
2021-08-20	You can now see closer-in views of the Henri situation this weekend on SV. Here is the latest GFS model example: https://www.stormvistawxmodels.com/sv/model/gfs-suite/12z/floater/25-mslp-10-m-wind
2021-07-09	Precipitation option added to teleconnection historical composites on StormVista. See example here: https://www.stormvistawxmodels.com/sv/teleconnection-composites/07-09/na/precip/ Find this under Features ---> Telecons and Forcing --> Historical Composites
2021-06-30	All-Ensemble Mean lines added to MJO RMM charts. See example here: https://www.stormvistawxmodels.com/sv/mjo/2021063000z//
2021-06-25	New page under Features ---> Model Metrics shows how well the grid-corrected forecasts performed for the prior day (Day 1 verifications). This is helpful to see how the models are handling significant temperature events like this weekend's big Pacific Northwest heat. See examples here: https://www.stormvistawxmodels.com/sv/model-verification-day1/tmax/2021062400z
2021-06-22	New tropical cyclone tracks are available on the SV API for the American, European, and Canadian ensembles. Learn more on the SV API page: https://www.stormvistawxmodels.com/api#tropical
2021-06-16	We have made the Houston close-up map floater view a permanent new map called Houston Metro. The floater map projection has been shifted to SoCal to track current strong heat there.
2021-06-03	Zoomed view of Dakotas for wind generation and Bakken support now available: See example here: https://www.stormvistawxmodels.com/sv/model/hrrr/12z/dakotas/146-wind-power-production
2021-06-03	New zoom map for New England now available. See examples via the European model here: https://www.stormvistawxmodels.com/sv/model/ecmwf-suite/00z/newengland
2021-05-26	New all-model hourly table comparison for cities and regions now available on StormVista under the Features ---> Hourly City Forecasts: Charts ---> scrolling down below line charts See an example here: https://www.stormvistawxmodels.com/sv/hourly-forecasts/KDCA/2021052600z
2021-05-14	100-meter wind anomaly forecasts are now available for the GFS ensemble weeklies - find them under the long range menu. https://www.stormvistawxmodels.com/sv/gfs-ens-weekly#power
2021-05-11	New region is added to the clustering products called Europe Expanded for a deeper view into Asia as well. See an example here: https://www.stormvistawxmodels.com/sv/model-cluster/mega/00z/europeexp/20210511/europeexp?unit1=F&unit2=in Find Clustering products under the SV Features menu along the top.
2021-05-03	Wind generation model compare pages now update live with incoming model data (no need to reload page). See example here: https://www.stormvistawxmodels.com/sv/windgen/2021050312z/ercot/ecmwf-eps Model compare pages are found under Features -> Renewables -> Wind Generation and then choose from the Compare Cycles drop down menu in upper right.
2021-04-28	The East Atlantic (EA) teleconnection has been added to StormVista. You can find it wherever you see all the other telecon information (API, model line charts, historical composites, telecon change line charts, etc).
2021-03-22	The GFS Op model will be upgraded to version 16 today at the 12z cycle. NOAA ran the 0z parallel, so we will have apples-to-apples changes for the 12-hour maps; however, they did not run a 6z cyle this morning, so the 6-hour change maps will be against the old model. The model is expected to update slower with an 8-minute delay at the start and an 11 minute delay by the finish of the cycle. The parallel GFS Op feed has now ended with this upgrade.
