As of today, October 4, 2023, it is too early to predict the exact date and strength of a winter storm that could hit the US.
However, the National Oceanic and Atmospheric Administration's Climate Prediction Center (CPC) has released its winter outlook, which forecasts above-average temperatures for much of the northern tier of the US and below-average temperatures for the southern tier.
La Niña: La Niña is a climate pattern that occurs when the surface waters of the tropical Pacific Ocean are cooler than average. La Niña winters tend to be colder and snowier than average in the northern tier of the US.
The Arctic Oscillation: The Arctic Oscillation is a climate pattern that describes the pressure difference between the Arctic and mid-latitudes. A positive Arctic Oscillation tends to be associated with colder and snowier winters in the US.
The jet stream: The jet stream is a band of strong winds that flows high in the atmosphere. The jet stream can influence the weather by steering storms into or away from different regions.
Based on these factors, the CPC is predicting an enhanced chance of above-average snowfall for the northern tier of the US, including the Great Lakes region, the Northeast, and the northern Rockies.
It is always a good idea to stay up-to-date on the latest weather forecast, especially if you are in an area that is at risk for winter storms.
