renderLayer was called during mounted() before selectedTime was seeded from the dataset, so buildWeatherTileUrl returned null and no tile layer was added. The overlay only appeared when the user clicked a forecast hour and update_weather_overlay fired. Seed selectedTime (and timelineData) from data attributes before the first renderLayer.
