1. How a negative PDO affects eastern winters:
2. Temperatures: Expect warmer-than-average conditions in the southern and mid-Atlantic states, with potential for some colder outbreaks.
3. Storms: The trough over the eastern U.S. can create a breeding ground for coastal storms, especially with the potential for cold air to be dumped into the region.
4. Snowfall: Snowfall can be variable, depending on how often and how long the cold air intrusions occur. 4. The conditions are favorable for coastal storms, which could produce significant snowfall in some areas.
Regional variation:
The negative PDO pattern is not uniform across the entire eastern U.S. Some regions, like the western Great Lakes and northern Plains, may experience colder-than-average conditions, while others, like the Southeast and Mid-Atlantic, are likely to be warmer.
