According to “The Old Farmer’s Almanac,” which goes on sale this week, the weather forecast for winter suggests that people from the Great Lakes to northern New England can expect cold and snowy weather, while west of the Great Lakes will see warmer weather.

The almanac‘s weather formula was created in 1818 and is based on planetary positions, sunspots and lunar cycles, none of which are used today by meteorologists.

Although most people don’t rely on the farmer’s almanac for accurate weather, many read the booklet just for fun.
