arkansas weather in december sets the stage for a unique and exciting narrative, offering readers a glimpse into the complexities of the state’s winter weather patterns. From the jet stream interactions to the temperature fluctuations, this topic is a treasure trove of interesting facts and figures that will keep you engaged from start to finish.
The state of Arkansas experiences a diverse range of weather conditions during the month of December, from cold fronts and rain to snow and ice. In this article, we will delve into the typical high and low-pressure systems that affect the state’s weather during this time, as well as the temperature fluctuations observed during the transition periods between cold fronts.
Weather Patterns in Arkansas in December Explained
December brings a mix of cold fronts, Arctic air masses, and moisture-laden low-pressure systems to Arkansas, resulting in diverse and dynamic weather patterns. As the state situated in the South-Central United States, Arkansas experiences a continental climate with four distinct seasons.
During the winter months, Arkansas is under the influence of the westerlies, a belt of winds that comes from the west and brings cold air from Canada and the Arctic. This sets the stage for a complex interplay between high and low-pressure systems.
Cold Fronts and Their Interaction with the Jet Stream
The jet stream, a fast-moving band of air in the upper atmosphere, plays a pivotal role in shaping Arkansas’ winter weather. The jet stream’s position and orientation determine the trajectory and intensity of cold fronts moving into the state.
One of the primary high-pressure systems influencing Arkansas weather in December is the North American cold high. This high-pressure system develops over the western United States and Canada, creating a region of sinking air that suppresses precipitation. However, when a cold front moves into the area, it can quickly replace this high-pressure system, leading to a significant drop in temperature.
Another critical factor in December weather is the subtropical jet stream, which originates from the Gulf of Mexico. This jet stream brings moisture from the warm waters of the Gulf, leading to increased precipitation chances when interacting with cold fronts. As the cold front advances, the subtropical jet stream typically intensifies the precipitation, producing a more substantial rain event.
Temperature Fluctuations During Transition Periods
When a cold front moves into Arkansas, the temperature suddenly drops, followed by a period of fluctuation as the front transitions. This period of temperature fluctuation is often the most unstable, with significant changes in temperature and precipitation.
During the transition period, temperature can oscillate by as much as 20-30 degrees Fahrenheit (10-15 degrees Celsius) over a short period of time. This rapid temperature shift contributes to the uncertainty associated with winter weather forecasting in Arkansas.
As the cold front advances, it brings a mass of cold air that spreads across the region. The cold air’s temperature and moisture content determine the type and intensity of precipitation, ranging from light snow flurries to heavy rain showers.
The interaction between cold fronts and the jet stream creates a complex weather environment, characterized by rapid temperature fluctuations, precipitation variability, and potentially hazardous conditions. Understanding these factors will help you make more informed decisions and stay prepared for the unpredictable winter weather in Arkansas.
Precipitation Expectations in Arkansas During December
In Arkansas, December marks the beginning of the winter season, and with it comes a mix of precipitation types, including snowfall, sleet, and freezing rain. As we delve into the precipitation expectations for Arkansas during December, it’s essential to examine the state’s historical data to understand the distribution of these weather phenomena.
Historical Average Monthly Precipitation in Arkansas
The National Centers for Environmental Information (NCEI) provides data on the average monthly precipitation for Arkansas from 1981 to 2010. According to the data, December sees an average precipitation of around 3.5 inches (89 mm) statewide. This value can vary across the state, with some areas receiving significantly more precipitation than others.
Comparison of Precipitation Patterns in Major Cities
To better understand the precipitation patterns in different parts of Arkansas during December, we’ll compare data from Little Rock, Fayetteville, Fort Smith, and Jonesboro. Here’s a table summarizing the average monthly precipitation for each city:
| City | Mean Precipitation (Inches) | Mean Precipitation (mm) | Percentage of Normal Precipitation |
|---|---|---|---|
| Little Rock | 3.53 | 89.8 | 96% |
| Fayetteville | 3.73 | 94.7 | 104% |
| Fort Smith | 3.28 | 83.3 | 90% |
| Jonesboro | 4.09 | 104.1 | 116% |
Prolonged Dry Spells Amidst Seasonal Rainfall
Although Arkansas experiences an average of 3.5 inches of precipitation in December, it’s not uncommon for the state to experience prolonged dry spells amidst seasonal rainfall. This phenomenon is attributed to the influence of the Southern Jet, a fast-moving weather system that can bring dry air from the Gulf of Mexico and the southern United States. When this jet stream interacts with the state’s winter weather patterns, it can lead to prolonged periods of dryness, despite the overall wetter conditions.
In terms of specifics, the NCEI data reveals that there are 4-6 days per month in December when precipitation is less than 0.5 inches across the state, indicating periods of relatively dry weather. However, these dry spells are often broken by significant snowfall or rain events, leading to a mix of precipitation types throughout the month.
This distribution of precipitation is typical of Arkansas’s weather patterns during the winter season, where the state experiences a mix of dry and wet conditions amidst the overall wetter conditions of the season.
