Part 3/8:
Significant cold air is accumulating in Canada, poised to plunge southward. While the warm weather has dominated for weeks, starting around January 5th to 7th, we can expect substantial Arctic blasts to sweep through the Midwest, the Ohio Valley, and into the Northeast. The jet stream is predicted to shift into a more northerly flow, allowing these cold fronts to persist. This pattern might lead to extended periods of below-average temperatures across the central and eastern United States.
