The heart of winter is here, and it’s bringing a significant and extended cold snap. While the exact temperatures and potential for snow remain uncertain, one thing is clear: this Arctic blast will be noteworthy both for its intensity and its duration.
Timing and Cold Outlook
The cold is expected to arrive about a week from today and will align with the climatologically coldest part of the winter, January 6–22. During this period, the average highs and lows are typically the lowest of the year. This Arctic outbreak, however, is likely to push temperatures even further below seasonal averages.
- How cold?
Current forecasts suggest temperatures will be at least 10°F below average, but how extreme the cold becomes depends on several factors, including snow cover to the north. Without sufficient snow cover, the incoming Arctic air mass could moderate slightly before reaching our region.- The spread in forecast guidance is large, so it’s important to focus on the average (mean) rather than extreme scenarios.
- How long?
Unlike some short-lived cold snaps, this one looks to stick around for 10 to 14 days, making it the longest-lasting cold spell in recent years.
Winter Precipitation: A Favorable Pattern
The pattern appears favorable for wintry weather, but not until after January 8. Specifics about snow, ice, or sleet are still too far out to predict with accuracy. It’s worth remembering that winter storms in this region can bring a mix of snow, ice, sleet, or cold rain.
Rather than relying on unreliable long-range snow maps, it’s better to watch for updates as we get closer. Think of it like a road trip: it’s easier to give an exact arrival time when you’re closer to the destination.
Key Takeaways
- Prepare for prolonged cold: Even if temperatures don’t reach the most extreme predictions, the long duration of this cold snap is a certainty.
- Winter precipitation remains uncertain: Stay updated for specific details on any snow or ice threats after January 8.
- Embrace mid-winter: This is a textbook winter pattern with cross-polar air diving deep into the eastern U.S., a reminder of what this season is all about.
A winter weather outlook vlog with updated ensemble runs is expected later today. Stay tuned and prepare for a frosty start to the new year!
