About Weather Workbench

The U.S. power industry runs on a small set of public weather data products: National Weather Service gridpoint forecasts, NWS active alerts, NOAA Climate Prediction Center 6–10 and 8–14 day outlooks, the U.S. Drought Monitor, GFS and European numerical weather prediction model output, and the National Hurricane Center advisories during hurricane season. These products are scattered across half a dozen federal websites, each with its own user interface, refresh cadence, and download format. Even people who have been in the industry for years end up bouncing between bookmarks to assemble a coherent operational picture.

Weather Workbench was built to collapse that workflow into a single ISO-organized view. The point is not to replace a paid market data subscription or a meteorology consulting contract. The point is to give a fast, credible first read on what the weather is doing across the nine major U.S. ISO regions, with the supporting context one click away. If you are a trader who wants to glance at degree day departures before opening your trading platform, an analyst writing a morning brief, an operator on call who needs to check the latest NWS alerts for a service territory, or a student trying to understand how weather translates into grid operations — this site is for you.

Every dataset on this site is sourced from federal agencies and publicly accessible APIs. No proprietary data, paid market data feeds, or licensed forecast products are republished here. Where the site computes derived values — for example, heating and cooling degree days — the formulas, base temperatures, and climatological normals are documented in full on theMethodology page.

Long-form articles in theLearn sectionare edited for accuracy and dated with their last revision. Where claims about specific historical events (Winter Storm Uri, Winter Storm Elliott, Hurricane Helene, the August 2020 derecho) are made, the underlying facts are drawn from publicly available regulatory filings, ISO event reports, and government incident summaries. Where forecasts or probabilistic outlooks are discussed, they are presented with their inherent uncertainty.

Weather Workbench is not a licensed forecast provider, a trading system, or an emergency information service. Always verify operationally critical data against primary sources — your local NWS forecast office, your ISO's official operations website, the National Hurricane Center, and your contracted weather vendor — before making operational or financial decisions.

All data displayed on this site comes from official U.S. government sources and a small number of public meteorology websites:
