What to expect from the post-Christmas snowstorm in the Hudson Valley

More Stories

Prepare for another round of snow for the Lower Hudson Valley. There are still uncertainties that surround this storm system, such as track, timing, and of course, how much snow will impact the region. However, here is what we can expect as of now.

Following Christmas, Friday will start cloudy and dry, with the approaching frontal system expected to bring snow to the region by Friday evening. There are signs that the snow will have periods of moderate and heavy bands during this event and will continue through Saturday.

At an early glance, we are expecting the lower Hudson Valley region to see a widespread range of 3-6" of snowfall accumulation. Comparing some long-range models, the GFS and Euro, which display two different scenarios and highlight the uncertainty of the storm tracks.

Scenario 1: The GFS model is suggesting a faster and more southerly approach. This would lead to Rockland and southern Westchester counties to see more snow accumulations, with sound residents having the chance to receive a mix of rain and snow that would lead to lower snow totals for eastern sections of Westchester County. Furthermore, this scenario would lead to lower totals in general to counties north of Westchester and Rockland, leading to more of a 2-4" of snow accumulation, while western Orange County would fall into the 3-6" range. This track would still lead to issues regarding travel from Friday night through Saturday morning. Treacherous road conditions from snow-covered roads, icy spots, and slick/wet roads and walkways as well. Plowable snow would still be expected from this scenario.
Scenario 2: The European model suggests a slower and northerly approach. This model is not only the boldest/bullish but also supports a worst-case scenario for the region. The latest data suggests the region will see more of a 6-9" snow accumulation range from this system. The system would tap into more moisture, have a slightly colder airmass, and begin more into Friday evening, and last through Saturday afternoon. There are still signals for periods of heavy and moderate snowfall, leading to rates of 0.5" to 1.0" or more per hour, which would help reach these numbers. This would absolutely lead to plowable snow and be quite the workout in regard to shoveling around your home and community.

Current takeaways

Prepare for treacherous travel back from Christmas, and for Friday into Saturday to bring treacherous conditions on the roads. At first glance, the consensus is to shoot in the middle of the two long range models. 3-6" of snow, which is still plowable snow and will require you to shovel around your place of residence.
