I’ve been trying to work on my Weather Forecast spread, and I don’t think it’s possible to make something realistic with only 3 cards… The last one, “other stuff card”, is really way too unclear to be understood correctly.
Therefore, here’s an improved version of it, with 5 cards :
For the 2nd card, you have to ask whether the weather is going to be hot or cold according to common sense (hot during summer, cold during winter).
The 5th card is, as usual, a synthesis that you can get by summing up the value of all the arcanas that you drew.
I’m using this spread to test whether the Tarot can forecast weather, and according to my current results, it has an accuracy of more than 70% ! That’s a pretty nice result if you compare it to meteorology.
