Latest Seasonal Forecasts for Illinois – A Mild Winter?

The NWS Climate Prediction Center released their latest seasonal forecasts today. Here are the results for Illinois. The biggest news is that Illinois has an increased chance of above-average temperatures and below-average precipitation for the winter months of December, January, and February. This forecast is based largely on the developing El Niño in the Pacific Ocean.

While the forecast of a milder winter may sound appealing, I would not leave the winter coat in the closet and throw away the snow shovel just yet. Two things to consider are: 1) this is not a 100% guarantee, other factors come into play in determining our winter weather, and 2) even a mild winter can contain short periods of intense cold and abundant snowfall.

  • Increased chance of below-average temperatures in September.
  • Equal chances of above, below, and near-average temperatures and precipitation for the fall months of September, October, and November. In other words, there is not much to say for fall in Illinois.
  • Equal chances of above, below, and near-average temperatures and precipitation for the spring months of March, April, and May.
