Something important to note, especially for this one which opens at 0800.

The weather changes at exactly 0000, 0800, and 1600, regardless of how long it takes for the icon and weather effects to change. If you want to log the entry at the time the window opens, it doesn't matter what the weather was before; it's the weather after the change that matters. If you get there at 0750 during a thunderstorm and wait for the clock to strike 0800, it will look like the weather is still thunderstorms for another few seconds, but your emote won't count unless the weather forecast was for the thunderstorms to continue.
