Timing and breadth of cold will be critical as February approaches
Good evening! We’ve discussed for some time now the expected development (or should we say return) of anomalous cold across the Northern Hemisphere, more specifically the southward movement of this cold into Canada and the United States. In our post yesterday, we dove into the details of why we are so confident that this cold will occur, and how the seeds are already planted and growing for the change to occur.
However, while we look ahead to the cold’s development and entrance into Canada and the United States, it will become increasingly important for us to understand the timing of the pattern change – including where the cold will be most prevalent first, and how it is expected to move across the country. While pinning down these details is an inherently imperfect science at this range, we can utilize multiple long-range forecasting tools and analogs to find clues as to how things will behave.
