NYC Winter Forecast 2023-2024: Warm start, volatile and active finish

The Winter of 2023-2024 will begin with warmer than normal temperatures and less snow than average in NYC. As the winter goes on, the weather is expected to become increasingly volatile. While temperatures may average near or slightly above normal, it is likely that NYC will see at least a few snowstorms and periods of colder than normal air. NYC’s 30 year average annual snowfall is 28.9″, and we expect slightly above average snowfall during the upcoming winter season.

Winter Forecast 2018-2019

Seasonal weather forecasting, especially when it comes to Winter, is one of the most challenging aspects of meteorology. It isn’t simply a guesstimate or an educated gamble. It is instead the product of months of research which typically begins several months prior. We’ve been piecing together ideas for this upcoming winter since Spring, and we’re excited to present our findings to you. In that respect, we are hopeful to break down the components of the forecast for you.

Instead of focusing on individual numerical indexes and values, we are going to try to paint a picture of the atmosphere and what it will be doing over the next few months – based on several global and hemispheric oscillations, conditions, and phenomena. This will lead us to the conclusions which we believe will be the guiding forces for us during the seasons ahead.

Winter Forecast 2017-2018

Seasonal forecasting is quite the challenge, but one we always look forward to. It seems every year we learn something new about the atmosphere. It is critical to have a fundamental understanding of how the atmosphere works, and the implications that changes from its base state can have on the weather pattern.

Instead of focusing on individual numerical indexes and their verbatim values, we are going to try to paint a picture of the atmosphere and what it will be doing over the next few months based on these phenomena:

  1. ENSO (El Nino Southern Oscillation) and tropical forcing
  2. High latitude behavior and blocking
  3. Analog years based on global pattern evolution

Winter Forecast 2016-2017

Seasonal forecasting is one of the most misunderstood aspects of meteorology. Not only is it a difficult task for the meteorologists themselves, but it is often difficult for readers and public viewers to understand the nature of the forecast. The root of the problem lies in the fact that seasonal forecasting is based on many different methods — all of which have tremendous variability and low percentage verification. Seasonal forecasting begins with an analysis of current conditions and atmospheric circulations, similar to any daily forecast. Beyond this point, forecasters use variables such as sea surface temperature anomalies, analogs, and comparative methodology to compile a forecast.

Some forecasters have detailed the mentality very well when they have stated that long term forecasting is very much about “What can go wrong” as opposed to “How will the forecast be correct”. Our job as meteorologists is to detail the aspects that have formed the foundation for our forecast, express our concerns and confidence in all aspects, and deliver the ideas which we have formulated as a result of our research and work in attempting to understand the patterns evolution over the next several months.

We will begin by highlighting several variables which we have researched. Each variable will be listed with a conclusion and prediction on its state during the winter, as well as the methodology and reasoning behind that forecast.
