My friend Jeanette told me about this crazy story she heard on NPR tonight about a crazy old guy who predicts weather by looking at pig spleens. At first, I didn't believe her, but apparently, this is a system that has been used for some time. It is even in the Farmer's Almanac!!
Apparently, they look at the thickness of different parts of the spleen and can predict the average temperature and precipitation. Starting from the top to the bottom the length of the spleen represents the months of January to June. Any lumps found along the spleen means snow, rain, wind, blizzards or lightening storms.
There is a caveat: The pig spleen forecasting only works from January to June and only within a 200-mile radius of where the pigs are kept.
Don't believe me? Check out these links.
And here is a schematic of famed meteorologist Gus Wickstrom's predictions from the pig spleen in 1998.
