boston massachusetts weather december is very cold. The topic of boston massachusetts weather december is a subject of great interest among weather enthusiasts and the general public alike. With the arrival of december, the city of boston in massachusetts is bracing itself for a period of cold weather, characterized by chilly temperatures and potentially snowy precipitation patterns.
in this article, we will delve into the intricacies of boston’s december weather, exploring how the north atlantic oscillation affects temperature and precipitation patterns, the impact of cold air masses on the city’s climate, and the challenges associated with forecasting winter weather in the region.
Boston Massachusetts Weather Patterns in December Are Influenced by the North Atlantic Oscillation
Boston’s weather patterns in December are significantly influenced by the North Atlantic Oscillation (NAO), a climate phenomenon that affects the atmospheric pressure difference between the Icelandic Low and the Azores High. The NAO’s fluctuation has a profound impact on temperature and precipitation patterns in the region, shaping the city’s winter weather.
The NAO works by influencing the strength and position of the low-pressure system over Iceland and the high-pressure system over the Azores. When the NAO index is positive, the pressure difference is large, leading to strong westerly winds that bring warmer air from the Gulf Stream to the North Atlantic. Conversely, a negative NAO index results in weaker winds and cooler temperatures. Boston’s proximity to the Atlantic Ocean and its location in a region susceptible to the NAO’s influence makes it particularly vulnerable to its effects.
Impact of NAO on Boston’s Temperature and Precipitation Patterns
The NAO’s influence on Boston’s temperature and precipitation patterns is evident in the city’s climate data. When the NAO index is positive, Boston experiences milder temperatures, with average highs ranging from 43°F to 48°F (6°C to 9°C). In contrast, a negative NAO index can lead to colder temperatures, with average lows dipping as low as 24°F (-4°C). Precipitation patterns also vary, with a positive NAO index typically resulting in above-average snowfall.
Unusual Weather Patterns in Boston During December
There have been instances where the NAO’s influence has led to unusual weather patterns in Boston during December. Here are three examples:
-
The “Polar Vortex” of 2013-2014: During this period, the NAO index was persistently negative, resulting in temperatures plummeting to -22°F (-30°C) on January 6, 2014. The extreme cold was caused by a kink in the polar jet stream that allowed Arctic air to penetrate the region.
-
The “Bomb Cyclone” of 2018: On January 4, 2018, a powerful low-pressure system brought heavy snowfall and strong winds to Boston, resulting in over 10 inches (25 cm) of snow and sustained winds of up to 40 mph (65 km/h). The NAO index was positive at the time, contributing to the system’s intensification.
-
The “Wet and Warm” Winter of 2015-2016: During this period, the NAO index was predominantly positive, leading to above-average temperatures and snowfall in Boston. The city experienced a record-breaking 64.9 inches (164.8 cm) of snow, with temperatures averaging 4°F (2°C) above normal.
Historical Data and Visual Aids
To illustrate the relationship between the NAO and Boston’s winter weather, let’s examine some historical data. Figure 1 shows the NAO index and Boston’s snowfall pattern from 1960 to 2019. The correlation between the two is evident, with periods of above-average snowfall coinciding with positive NAO indices.
| NAO Index | Snowfall (_inches) | Temp (°F) |
| — | — | — |
| Positive | Above Average | Above Average |
| Negative | Below Average | Below Average |

Impact on Local Agriculture, Transportation, and Tourism
The NAO’s influence on Boston’s weather has significant implications for local agriculture, transportation, and tourism. When the NAO index is positive, above-average snowfall and warmer temperatures can lead to:
-
Increased snow removal costs for local municipalities
-
Potential disruptions to air and ground transportation due to snow and ice accumulation
-
Snow-related business closures and decreased tourist activity
However, a positive NAO index can also lead to increased opportunities for winter sports enthusiasts, such as skiing and snowboarding, contributing to the local economy. On the other hand, a negative NAO index can result in below-average snowfall, leading to increased costs for municipalities and businesses due to decreased tourism.
Understanding the NAO’s influence on Boston’s weather enables residents, businesses, and policymakers to prepare for and adapt to the varying climate conditions, ultimately mitigating the impacts of extreme weather events.
Boston’s December Weather Forecasting Challenges
Boston’s December weather forecasting is a complex process that involves various computer models, satellite and radar imagery, and expert decision-making. One of the main challenges faced by forecasters is accurately predicting the movement and intensity of winter storms that can bring heavy snowfall, strong winds, and coastal flooding to the area.
Role of computer models in predicting Boston’s December weather, Boston massachusetts weather december
Computer models play a crucial role in predicting Boston’s December weather, providing forecasters with detailed information about temperature, precipitation, and other weather conditions. However, these models have strengths, weaknesses, and limitations that can affect their accuracy. For example, high-resolution models such as the Weather Research and Forecasting (WRF) model can provide detailed information about local weather conditions, but they can be computationally expensive and may require significant amounts of data to run. On the other hand, larger-scale models such as the Global Forecast System (GFS) model can provide information about larger-scale weather patterns, but their resolution may not be sufficient to accurately predict local weather conditions.
Using satellite and radar imagery to track winter storms
Satellite and radar imagery are essential tools for tracking winter storms in Boston, providing forecasters with real-time information about the storms’ movement and intensity. Satellite imagery can provide information about the storm’s clouds, precipitation, and wind patterns, while radar imagery can provide detailed information about the storm’s trajectory and intensity. However, satellite and radar imagery have their own set of benefits and challenges. For example, satellite imagery can be affected by clouds and precipitation, while radar imagery can be affected by the resolution and frequency of the radar system.
Issuing winter weather advisories and warnings
Issuing winter weather advisories and warnings is a critical task for forecasters during Boston’s December weather. This process involves analyzing data from computer models, satellite and radar imagery, and other sources to determine the likelihood of significant weather events, such as heavy snowfall or coastal flooding. The decision to issue a warning or advisory depends on various factors, including the severity of the weather event, the potential impact on the community, and the time frame for the event.
