Our AI observer runs twice daily (11:55 AM and 3:55 PM AKDT). At each run it captures a webcam snapshot, reads the live SGXA2 sensor data, and compares against the NOAA forecast for that specific hour — so instead of "NOAA said 28°F sometime today," you get "NOAA said 28°F at 11 AM vs actual 30°F at that moment." The data shown reflects conditions at the time the AI ran, not live conditions — so it may differ from the Live Conditions page which updates every 15 seconds.
