4 Predictions On When Spring Will Come To Wyoming So far the Farmers Almanac for the winter of 2020-21 has not been too far off. Typically, the Almanac is only 25% accurate in their yearly forecasts, but the Almanac got off to a good start this year. If we stick with them we see the weather returning to mild and dry right into spring. Sorry, but I'm not trusting Punxsutawney Phil to tell me anything. As Live Science reports, the Groundhog Club's records show that Phil has predicted more winter 103 times, and an early spring just 19. Based on data from the Stormfax Almanac, that means Phil's accuracy rate is an abysmal 39 percent.
