NOAA's 2024-2025 Winter Weather Forecast: Snow Storm Predictions for Your Area

The National Oceanic and Atmospheric Administration (NOAA) has released its annual winter weather forecast for the 2024-2025 season, providing insights into the expected snowfall and temperature patterns across the United States. This article delves into the key predictions and what they mean for different regions, helping you prepare for the upcoming winter season.

1. **La Nia's Impact on Winter Weather**

One of the primary factors influencing this year's winter weather is the anticipated return of La Nia. According to NOAA, there is a 66% chance that La Nia will develop during September-October-November and a near 70% chance that it will persist through the winter of 2024-2025. La Nia events are characterized by cooler-than-normal Pacific Ocean surface temperatures, which can lead to heavy precipitation and snowfall in the Pacific Northwest and other northern regions.

During a La Nia event, cold waters in the Pacific push the jet stream northward, typically resulting in heavy rains and flooding in the Pacific Northwest and Canada. This also means that winter temperatures are generally warmer than normal in the South and cooler than normal in the North.

For the upcoming winter season, regions such as Washington, Oregon, northern Idaho, Montana, and parts of Colorado, Wyoming, and Utah are expected to see lower-than-average temperatures paired with higher-than-average precipitation levels. This outlook sets these regions up for an increased likelihood of snowfall and potentially incredible snow conditions.

2. **Regional Snowfall Predictions**

While La Nia's influence is significant, the specific snowfall predictions vary by region. Heres a breakdown of what you can expect:

Pacific Northwest: The Pacific Northwest is expected to experience above-normal precipitation and snowfall. This is due to the typical La Nia pattern where cold air meets moisture along the west coast of North America, delivering plenty of snow to states like Washington and Oregon.

Great Lakes Region: The Great Lakes region, including states like Minnesota, Wisconsin, and Michigan, is also predicted to see above-normal precipitation and potentially snowier-than-average seasons. However, it's noted that temperatures in these areas may be mixed and could dip below average, leading to potentially good snow conditions at ski resorts.

New England and Northeast: The Northeast and New England are expected to have above-normal temperatures but promising precipitation outlooks for skiers and snowboarders. Above-normal precipitation is favored for these regions, which could result in significant snowfall at higher elevations despite warmer temperatures affecting lower elevation snow quality.

Southwest and Southern States: In contrast, the Southwest and southern states are predicted to experience warmer-than-normal temperatures. This includes regions like Colorado, New Mexico, and parts of New England, which might see slightly above-average temperatures during the winter months.

3. **Temperature Outlook**

NOAA's temperature forecast for the upcoming winter season indicates that the majority of the southern half of the United States will experience warm temperatures. This includes states like Colorado, New Mexico, parts of the Mid-Atlantic, and well into New England.

However, there are some areas expected to see cooler-than-normal temperatures. Southeastern Alaska is likely to experience below-normal temperatures, while northwestern Alaska may see above-normal temperatures due to recent trends and observed below-normal sea ice extent.

The Temperature Outlook for December through February also shows slight differences in the American Southwest with more of Arizona, New Mexico, and Southern Colorado favored to receive slightly above-average temperatures.

4. **Precipitation Outlook**

NOAA anticipates heavy precipitation along the Pacific Northwest region as well as around Michigan up through Maine. This outlook pairs well with the below-average temperatures expected in the PNW but southeastern Alaska is expected to see below-average precipitation early in the winter.

The combination of cold temps and lots of precipitation means that if everything goes according to plan, Washington, Oregon, Idaho, and western Montana mountains should see a substantial start to winter. This would be huge for these areas as they havent had consistent snowfall in the early season for some time.

Looking at the latest precipitation outlook for the heart of winter 2025, there are slight shifts in snowfall expectations in the American Northwest. The dark green bubble of average precipitation shifts inland moving away from the western coast into interior Washington, Idaho, and Western Montana. This positions Schweitzer, Whitefish, Big Sky, and Bridger Bowl as viable cold smoke powder havens.

In addition to these regional predictions, it's important to note that long-range forecasts are rarely accurate. These forecasts cover three months but know that skiing quality improves and degrades with storm cycles lasting a few days to a week.

5. **Preparing for Winter**

While NOAA's predictions provide valuable insights into what we might expect during the upcoming winter season, it's crucial to stay informed through more frequent updates.

For those hoping for a lot of snow in the DC area this winter, NOAA forecasters suggest keeping an eye on short-term forecasts for the most accurate information. Websites like OpenSnow offer 10-day snow forecasts and expert snow forecasters to help you find the best snow conditions for your weekend trips or destination ski vacations.

Ultimately, preparing for winter involves being adaptable and staying informed about changing weather conditions. Whether you're a skier, snowboarder, or simply someone who enjoys winter activities, understanding these predictions can help you make the most out of this season.
