SCP Foundation

A humanoid SCP, born with an anomalously high barometric pressure surrounding him or her. Areas affected extend to about 4km (8km diameter) in either direction. The average barometic pressure around them is ~1060mb (millibars). Government weather satellites captures a hole in passing clouds at all levels of the atmosphere over the exact location of the PoI.

[Exact location of the Scip’s location is TBD, but it will reside in a remote village.]

The village where the Scip resides is experiencing a major localized drought that happens to be going on as long as the Scip has been alive. Once the Scip is found and removed by the Foundations, the viilage experiences its first rain in [X] amount of years.

Sounds pretty mundane… But wait! There’s more!

The Scip is contained by the Foundation, but weather patterns start to change on large scale. After [X] amount of months, an anomalous pattern develops, troughs and ridges go into an abnormal semi-permanent state. A large scale drought lasting [X] amount of years ensues. The area affect [TBD km²] is severely parched. Miraculously, no wildfires broke out… yet.

On TBD date, patterns unexpectedly change. Ridges and troughs shift and amplify into a pattern favourable for fire weather. The facility experiences dew points and humidity in the single digits and winds over hurricane force. Eventually a wildfire starts and heads straight towards the facility. The facility evacuates, and Scip is moved to a different facility only for the same thing to happen.

What the Foundation does not know is the reason why this is happening is simply because the Scip feels out of place. (I may have the Foundation find out eventually.)

This article will be heavily based on weather reports from facility meteorologist, and weather charts/maps.

The origin of the Scip’s anomalous properties is unknown.

I don't know if I'm all that keen on it being based on the well-being of a human SCP though. The way you describe it sounds like a cross between Douglas Adams' "Rain God" (who actually hates rain, but the clouds love him and just want to be near him) and Lauranna from Men in Black II ("You're not sad because it's raining; it rains because you're sad. You are the light of Zartha."). Cause I get the idea it's the weather being focused on the person; the person isn't controlling it. Like, what happens if the person dies, even just from old age? If they fall and break their leg is there some kind of weather related natural disaster? The containment procedure would essentially be "make sure this person is always feeling confident and optimistic about life in general" which doesn't seem to me to provide a big enough hook to hang all this science on.

I did think of another SCP that is weather-affecting: The Old Man of Crater Lake. That centers on an artifact with a badass backstory in addition to its anomalous properties.

Since you want to involve a lot of scientific descriptions of weather patterns, you'll need a narrative catalyst which makes the specifics of those weather patterns crucial to the movement of the plot. There has to be some kind of causal link between the weather patterns and something the Foundation can influence — though perhaps not easily. My advice for developing this idea is to focus on that aspect of the story. What is the exact relationship between the weather patterns and the object or person of their focus? How does the Foundation discover this relationship, and how difficult is it for them to keep either the weird weather or their efforts to control its source under the Masquerade?
