In today’s video from Direct Weather, we dive into a significant weather pattern shift affecting the U.S. Northeast and beyond. We’ll examine an ongoing snowstorm in the northeastern states, an incoming Arctic blast set to arrive tonight, and a major lake-effect snow event poised to unfold over the next few days. Additional cold air is on the horizon, with multiple snowstorm threats developing across the country. We’ll also analyze weather models, comparing the European and GFS predictions, to uncover the accuracy of current forecasts. Stick around for a detailed breakdown of what to expect as we move into early December.
Key Points
Current Weather Overview
- Ongoing Snowstorm: Heavy snowfall in northeastern states, especially Vermont, New Hampshire, and Maine, with accumulations reaching 6–10 inches in some areas.
- Arctic Blast Tonight: A powerful cold front will usher in frigid conditions, drastically changing temperatures by tomorrow morning (Thanksgiving to Black Friday).
- Lake-Effect Snow Event: Heavy snowfall bands expected for Michigan, Ohio, Pennsylvania, and New York, with rapid accumulation rates due to intense snowfall.
Weather Model Insights
- Model Comparisons:
- The European model has accurately predicted the current snowstorm’s track.
- The GFS model initially placed snowfall too far south, failing in this case.
- Future snowstorm tracking will favor the European model for higher reliability.
- Key Takeaway: Success rates of models vary over time, necessitating consistent tracking of their performance.
Upcoming Patterns and Threats
- Friday-Sunday (Nov. 29–Dec. 1): Intensifying cold with continued lake-effect snowfall; temperatures will drop further each day.
- Monday-Tuesday (Dec. 2–3):
- Expanding Arctic air impacting southern states like the Carolinas.
- Potential for continued lake-effect snow and a new synoptic snowstorm.
- December 5–7:
- Brief warm-up followed by another Arctic blast.
- New snowstorm threats along the East Coast, possibly reaching North Carolina.
Snowfall and Temperature Highlights
- Lake-Effect Snow:
- Initial snowfall could exceed 5 feet in some Great Lakes regions.
- Likely the most significant lake-effect event this season.
- Broader Snowstorm Events:
- Heavy snowfall in the Midwest, Appalachian Mountains, and Northeast.
- Synoptic storms (snowstorms driven by low-pressure systems) enhancing snowfall beyond lake-effect regions.
- Temperature Anomalies:
- Widespread below-average temperatures across the East through mid-December.
- Short warm-ups followed by extended Arctic air intrusions.
Long-Term Outlook
- December 7–13:
- More Arctic blasts anticipated.
- Coastal storm possibilities, particularly impacting states from North Carolina to Maine.
- Decreasing lake-effect snow due to cooling lake temperatures.
Impacts on Ski Resorts
- Western U.S.: Below-average snowfall continues, creating challenges for ski resorts in the Rockies and Cascades.
- Eastern U.S.: Significant snowfall in the Midwest, Great Lakes, and Appalachian regions bolsters ski opportunities.
