What updates, and how to use it
The page requests the latest available National Weather Service forecast when you open it or choose a state. While this page remains visible, it checks again every hour. You can also refresh manually. The forecast issue time and the time of the last successful check are displayed separately.
The next four available forecast periods show the reported temperature, wind and chance of precipitation. A missing precipitation value is shown as unavailable. Older or expired data is identified; an unavailable feed is not replaced with invented conditions.
Use the forecast for a planning conversation
Ask your installer whether the forecast changes the site visit, delivery or work schedule. Check the forecast and any alerts for the actual property with NWS before a visit. This city-level overview does not determine whether roof work is safe, predict panel output or estimate system savings.
