Weather Forecast - Snow and Low Wind Chills
Depending on where you live, snow accumulations could range from a couple of inches to six inches. The greatest accumulations will be found in areas with hills and grassy areas, such as northern Virginia, southeastern Pennsylvania, and northern New Jersey, as well as in western Connecticut. As a result, roads in urban areas could become slick, especially if the snow falls for an extended period of time. More
Temperatures will be colder than normal
The temperature will be colder than normal this winter, but there will also be plenty of rain and snowfall. Coldest periods will be in mid-December and early January, and there will be above-average snowfall in northern areas. The heaviest snowfall will fall in early January and mid-February. The chance of a snowstorm will be equal during these three months.
The winter season will be colder than normal for most of the U.S., although some areas may have slightly warmer temperatures. The weather is influenced by several major climate systems, including the continued warm phase of the Atlantic Multidecadal Oscillation (AMOC), the neutral to positive North Atlantic Oscillation, and the negative Pacific Decadal Oscillation. These patterns are connected ocean-atmosphere systems and can affect weather long-term. For the Northeast, this winter will be colder than normal because of snow, while southern areas will be warmer.
The chilly periods in New York are likely to occur in late December and early January. The wettest parts of the state will experience above-normal temperatures, while drier regions will experience above-normal snowfall. In the northern Rockies, the snowiest periods will be mid-December and early January.
Snowfall will be above normal
The forecast for the coming winter season is for snowfall to be above normal in most areas. This will be true for the east as well as parts of the west. The coldest times will be early December to mid-January. Mid-January to early February will have the most snowfall. The deep south is expected to be slightly warmer than average this winter. However, the northern portion of the U.S. will experience slightly below-normal temperatures.
This winter's winter precipitation will be above normal from Maine to southeastern Virginia. Between the eastern seaboard and the Rockies, the temperatures will be below average. From central New England through northern North Carolina, snowfall will be above normal. Snowfall will also be higher across the southern Plains, southern Rockies, and Ohio Valley.
The temperatures in the north will be colder than usual for most areas, while the coldest periods will be mid-December and early February. Snowfall will be above-normal in many regions, but will be below-average in most areas.
Wind chills could cause frostbite on exposed skin
The low wind chills can cause your body to lose heat much more quickly than the actual temperature. In a typical cold winter day, you could suffer frostbite in as little as 15 minutes if you're exposed to the wind. Fortunately, frostbite is not as common in Colorado as it is in other climates. But if you're caught in such a situation, it's important to get medical attention immediately.
The wind chill index helps determine the danger level. It takes into account the body's heat loss and uses a combination of temperature and wind speed to calculate the wind chill. For example, a minus five degree temperature with a 20-mph wind will cause a wind chill near minus 30 degrees. At that level, the risk of getting frostbite is the same as it would be if the weather was perfect.
The National Weather Service has issued a wind chill advisory for the state, including Steuben, Allegany and Ontario counties. The advisory also covers three counties in the far northwest of the state. This cold weather could cause frostbite in as little as 30 minutes, so you need to wear extra layers and limit your time outdoors.
Impacts of La Nina on winter weather
The biggest impact of La Nina is felt in the winter months. During this period, the weather tends to be warmer in the southern United States and cooler in the northern U.S. This is because the jet stream is tilted more to the east and causes more blocking high pressure systems. The result is a more active winter. Cold air from the Pacific Northwest spills into the northern Great Plains, leading to wetter, stormier conditions there.
In addition to its impacts on winter weather, La Nina is known to influence summer temperatures. It also has the potential to influence heatwaves in Texas. The current state of La Nina is expected to persist through the rest of this winter and early next spring, according to the Climate Prediction Center.
Stronger La Nina events have more influence on the winter climate pattern over western North America. On the other hand, weaker La Nina events are associated with above-average snowfall over the northern U.S. A weak La Nina indicates that Pacific forcing is weaker than usual, and it may indicate the influence of the Arctic Oscillation on winter weather.
