I will admit that weather is hard to predict, so there's a good chance that I'm completely wrong and a dire prediction for Missouri and Illinois for the first week of December is accurate. Let's pray it's not.
Let's start by emphasizing how unpredictable weather in Missouri and Illinois is. Keep that in mind as I warn you to keep your eyes on the weather forecasts as we get closer to Thanksgiving as advanced forecasts show that could involve snow for both states right after the holiday.
It's the eternal question. How much snow will Missouri get this winter? Sure, you could follow forecasts from the National Weather Service and the Climate Prediction Center from NOAA. But, there's a more organic way and it has to do with squirrels. I'll explain.
Have you ever asked a question then immediately regretted it? That's exactly what happened to me when I asked Farmer's Almanac when Missouri would see its first real snow of the season. When I got the answer, I was very sorry for the question.
