The nighttime Grand eruption wait started with overcast skies and a Rift eruption. By the time Rift had quit the clouds had turned to a strong wind and some showers. But it only took a half hour for things to clear back up. When Grand did start, the moon, while dimmed by some thin clouds, was enough to illuminate a nice three burst eruption.
The Castle eruption during the wait had to be one of the more powerful it's had in a while. Or else the wind conditions really amplified the noise of the steam-phase. It was still an impressive rumble an hour after the start of the eruption.
The afternoon Grand eruption was another one of its cases of having a delay at a reasonable time, thus making sure there's another long interval.
Here's what an eruption of Old Faithful looks like when viewed from the Snowlodge. Another lost opportunity we've gotta live with for the next few decades.
