It may be gut-check time for groundhogs.

A Saskatchewan man says if you give him a pig's spleen, he can tell you what the weather's going to be this spring.

Jeff Woodward learned the Swedish practice of making pig spleen predictions from his uncle Gus, who gained notoriety prognosticating pig spleens for 40 years.

"It wasn't one of my career ambitions," Woodward said. "But it seems like a natural fit now." 

As pigs prepare for winter, they leave fatty signatures on their spleen. Lumps indicate precipitation, while shape and texture point to temperature.

Flying in the face of recent groundhog predictions, Woodward isn't expecting an early spring and says brace for more snow.
