Interesting! As a contrast, I'm using historic weather data to predict future weather - couples use my free wedding weather predictor to find the perfect date for their wedding: https://dropory.com/
Cool! If you end up wanting to expand beyond just the nearest weather station (forgive me if I've misunderstood your process), you could look into ERA5 - free Numerical Weather Prediction 'reanalysis' of past weather on a regular grid. openmeteo has some open source tools for extracting time series data from it.
But, although you get good spatial coverage, the drawback is 'the map is not the territory' - the model's representarion of reality doesn't perfectly mesh with the weather on the ground.
