Analyzing Current and Upcoming Weather Patterns
Let’s dive into the current weather situation, a snapshot taken this morning and afternoon. The Mid-Atlantic and Northeast are experiencing moderate to heavy snowfall, surpassing initial expectations. Many areas are seeing 4 to 6 inches, exceeding the predicted 2 to 4 inches. As we move into the evening, the storm is progressing further into the Northeast, particularly impacting Vermont, New Hampshire, and Maine.
By tomorrow morning, Wednesday the 17th, the storm will have passed, leaving behind frigid temperatures due to an Arctic air mass settling over the eastern states. Another storm is on the horizon, gathering strength in the Northwest, leading to heavier snowfall for the Cascades and the Rockies on Wednesday, January 17th.
Transitioning into Thursday the 18th, the snowfall shifts towards the Rockies and plains, with a broad low-pressure system forming over the Ohio Valley, Mid-Atlantic, and Southern Ohio Valley. The weather pattern suggests an active period with storm systems moving in from the Northwest.
As we progress towards Friday, low-pressure areas converge, resulting in a significant snowfall event reminiscent of the recent storm. Areas like West Virginia, Virginia, Maryland, and DC are in the spotlight for Friday morning and afternoon, extending into the Del Marva and Southern New Jersey. Despite potential shifts in the storm’s path, a light to moderate snowfall event in the East seems likely, accompanied by very cold air on Saturday, January 20th.
Long-Range Weather Outlook
Looking ahead, numerous storm systems are developing over the western states, indicating a shift towards a milder pattern in the East. The Northern Jet, reaching all the way up to Canada, allows warmer, more humid air to penetrate the eastern and central states.
For cold and snow enthusiasts, there’s good news. The anticipated warmup is expected to be short-lived, spanning roughly from the 21st to the 28th. While some areas may experience milder temperatures, pockets of cold air will persist, supporting snowfall events, especially in the northern regions.
As we move into the latter part of the month, a positive Pacific North American oscillation (PNA) develops, signaling a shift in the weather pattern. The trough moves eastward, and the ridge diminishes, indicating the return of colder temperatures and potential snowfall opportunities. By the end of the month and early February, the East may experience another round of wintry weather.
Despite the temporary warmth, the long-range forecast holds promise for cold and snow lovers. Stay tuned for further updates as we navigate through these dynamic weather patterns.
