I can remember my Mother using this old method of predicting the weather for the upcoming year.
On the 6th of January, late at night after everyone's gone to bed, cut an onion in half. Separate the rings and place twelve of the 'cups' in a row - January will be on the far left, then February, and so on with December ending on the far right. I personally like to place the cups on a large cookie sheet.

Place 2 tspn of salt in each onion 'cup'. Leave overnight. The next morning look at the salt. How wet or how dry the salt is predicts how wet or how dry that month will be.
** DO NOT talk to anyone from the time you cut the onion until the next morning. **

Another way some folks predict the upcoming year's weather is to make note of the weather for the first 12 days of January. What those days hold in the way of sunshine, temperatures, & precipitation foretell what the upcoming months will be like.
Wanna compare notes in June???
