While much of the state is expected to see wetter-than-average conditions, areas near the Great Lakes may face more significant rain than usual. Meanwhile, temperatures are forecasted to dip below normal in certain regions, setting the stage for a challenging month ahead. The unexpected blend of wet weather and colder-than-usual temperatures is raising concerns among meteorologists and residents alike.
Above-Average Precipitation Expected Across New York
According to the National Weather Service, most of New York is set for wetter-than-normal conditions in December. The state has a 33-40% chance of receiving above-average rainfall, with the likelihood increasing further in the western and northern parts of the state, including areas near the Great Lakes. These regions are predicted to face a 40-50% chance of above-normal precipitation, which could bring heavier rains and possibly even snow in some places.
For comparison, Central Park typically receives around 4.38 inches of rain in December, based on data from the National Oceanic and Atmospheric Administration. However, with above-average precipitation expected, residents of New York City and surrounding areas may see rainfall totals surpass this average.

Experts suggest that this wet pattern could create disruptions for daily life, with potential for increased flooding, particularly in flood-prone areas. While the wetter forecast may be an inconvenience for some, it could also play a role in replenishing water reserves, particularly in areas that have experienced drought in recent months.
Colder Temperatures Likely for Upstate New York
Alongside the wet conditions, some parts of New York will also experience colder-than-average temperatures. The Climate Prediction Center’s outlook indicates that upstate New York, especially the northern and western regions, has a 33-40% probability of experiencing below-average temperatures this December. This aligns with predictions for a slightly colder winter across much of the northeastern United States.
The cold temperatures, combined with the expected precipitation, could lead to challenging travel conditions, particularly in upstate New York where snowstorms are not uncommon. The state’s snowplows and emergency services will likely need to be on high alert as the region contends with possible snow accumulation and freezing conditions.

Downstate New York, however, may experience more moderate temperatures, with no clear lean towards either above- or below-average readings. In New York City, for example, average temperatures during December usually hover around 39.1°F, and this forecast suggests that the city will likely see typical December weather.
While the overall outlook points to a colder-than-usual winter for much of upstate New York, the fluctuating temperatures and wet conditions will be a key factor for residents as they prepare for the season. Those in more southern areas can expect relatively seasonal conditions, though the increased rainfall could still cause disruptions.
New Yorkers should expect a December that’s wetter and, in some areas, colder than usual. The Climate Prediction Center’s forecasts suggest a combination of precipitation and cold that could affect daily life, particularly in upstate regions.
