Brace yourself, Pennsylvania, as the winter of 2023-2024 promises to be a frigid and unrelenting one. Accuweather’s long-range forecast predicts a season marked by extreme cold and abundant snowfall, surpassing the harsh conditions of the previous winter. Prepare for treacherous icy roads, bitterly cold temperatures, and the potential for power outages as this unrelenting winter takes hold.
Furthermore, the impact of a La Niña weather pattern will amplify the winter’s severity. La Niña, a natural cooling of the Pacific Ocean, typically leads to colder and drier conditions in the eastern United States during the winter months. This year, its presence will intensify the frigid temperatures and increase the likelihood of significant snowstorms. Consequently, residents should anticipate an extended period of bone-chilling cold and hazardous driving conditions throughout the season.
As the winter progresses, the frigid grip will extend beyond January and February. Accuweather predicts that the cold and snow will linger into March, with below-average temperatures persisting well into spring. This extended period of wintery conditions will pose challenges for daily life, including increased energy consumption for heating, disruptions to transportation, and potential health risks associated with prolonged exposure to the cold.
Unusually Mild Temperatures
The winter of 2024-2025 is expected to be unusually mild in Pennsylvania. The average temperature is forecast to be 3-5 degrees Fahrenheit above normal. This is due to a combination of factors, including a strong El Niño pattern in the Pacific Ocean and a weak polar vortex in the Arctic. El Niño is a natural climate pattern that occurs every few years, and it typically leads to warmer and drier winters in the eastern United States. The polar vortex is a large area of cold air that sits over the North Pole. When the polar vortex is weak, it can allow cold air to escape into the mid-latitudes, leading to colder winters. However, the polar vortex is expected to be weak during the winter of 2024-2025, which will help to keep temperatures mild in Pennsylvania.
The following table shows the average temperature and precipitation for Pennsylvania during the winter of 2024-2025, as compared to the normal values:
| Month | Average Temperature (°F) | Normal Temperature (°F) | Average Precipitation (inches) | Normal Precipitation (inches) |
|---|---|---|---|---|
| December | 35-40 | 30-35 | 3-4 | 3-4 |
| January | 30-35 | 25-30 | 3-4 | 3-4 |
| February | 35-40 | 30-35 | 3-4 | 3-4 |
Increased Precipitation and Snowfall
The 2024-2025 winter in Pennsylvania is expected to bring above-average precipitation and snowfall thanks to a combination of factors, including a La Niña pattern in the Pacific Ocean and a strong jet stream. The jet stream is expected to be positioned further south than usual, allowing cold air from Canada to penetrate into the Northeast. This will result in more frequent and intense snowstorms.
Snowfall Amounts
Snowfall amounts are expected to vary depending on location, with higher elevations receiving the most snow. Here is a table with estimated snowfall amounts for different regions of Pennsylvania:
| Region | Snowfall (inches) |
|---|---|
| Northeast | 60-80 |
| Central | 40-60 |
| Southwest | 20-40 |
| Southeast | 10-20 |
Severe Storm Threats
Pennsylvania is no stranger to severe weather, and the 2024-2025 winter season is expected to be no exception. The National Weather Service (NWS) has issued a winter weather outlook for the state, predicting that there is an enhanced risk of severe storms, including:
Tornadoes
Tornadoes are relatively rare in Pennsylvania, but they can occur. The NWS predicts that there is a slightly increased risk of tornadoes during the 2024-2025 winter season. This is due to a combination of factors, including warmer-than-average temperatures and increased wind shear.
Severe Thunderstorms
Severe thunderstorms are more common in Pennsylvania than tornadoes. The NWS predicts that there is an enhanced risk of severe thunderstorms during the 2024-2025 winter season. This is due to a combination of factors, including:
- Warmer-than-average temperatures
- Increased wind shear
- Moist air from the Gulf of Mexico
High Winds
High winds are also a hazard during the winter season in Pennsylvania. The NWS predicts that there is an enhanced risk of high winds during the 2024-2025 winter season. This is due to a combination of factors, including:
- Strong jet stream
- Cold fronts
- Thunderstorms
The NWS urges Pennsylvanians to be prepared for severe weather during the 2024-2025 winter season. Make sure you have a plan in place for what to do if a severe weather warning is issued. You should also have an emergency kit on hand, including food, water, first aid supplies, and a battery-powered radio.
Subzero Wind Chills
Pennsylvania is expected to experience some of its coldest weather in years during the 2024-2025 winter season. Wind chills are expected to reach subzero temperatures, even in the southern and eastern parts of the state. This is due to a combination of factors, including a polar vortex and a strong jet stream.
Wind Chill and Impact
Wind chill is the temperature that your body feels when the wind is blowing. It is always colder than the actual air temperature. As the wind speed increases, the wind chill temperature decreases.
Wind chill can cause serious health problems, including hypothermia and frostbite. Hypothermia occurs when your body loses heat faster than it can produce heat. Frostbite occurs when your skin freezes. Both hypothermia and frostbite can be life-threatening.
How to Protect Yourself from Subzero Wind Chills
There are several things you can do to protect yourself from subzero wind chills, including:
- Dress warmly in layers.
- Wear a hat, gloves, and scarf.
- Cover your face with a mask or scarf.
- Avoid being outside for long periods of time.
- If you must be outside, take breaks in warm places.
- Drink plenty of warm fluids.
Wind Chill Chart
The following table shows the wind chill temperature for different wind speeds and air temperatures.
| Wind Speed (mph) | Air Temperature (°F) | Wind Chill (°F) |
|---|---|---|
| 5 | 32 | 23 |
| 10 | 32 | 13 |
| 15 | 32 | 4 |
| 20 | 32 | -6 |
| 25 | 32 | -16 |
Lake-Effect Snow and Icing
During early and mid-winter, Pennsylvania often experiences extreme lake-effect snowfall and icing. Lake-effect snow occurs when cold air from the north moves across the relatively warm waters of Lake Erie and Lake Ontario, causing the air to pick up moisture. This moisture rises into the atmosphere and condenses into clouds that produce snow and icing.
The amount of lake-effect snow can vary significantly from year to year, but it can often accumulate quickly and reach depths of several feet. Lake-effect snow is particularly common in western Pennsylvania, where the winds from the northwest can carry large amounts of moisture from Lake Erie.
Lake-Effect Snow and Icing Forecasts
The National Weather Service issues lake-effect snow and icing forecasts for Pennsylvania during the winter months. These forecasts help people to prepare for and mitigate the potential impacts of lake-effect snow, including:
- Travel disruptions

There are a number of things that people can do to prepare for lake-effect snow and icing, including:
- Stay informed about weather forecasts and warnings.
- Have an emergency plan in place.
- Stock up on food, water, and other essential supplies.
- Have a generator or other backup power source available.
- Be prepared to evacuate if necessary.
- Follow the instructions of local officials.
