December Snow Pattern Intensifies: Direct Weather Forecasts Historic Month
The latest forecast from Direct Weather will please skiers and snowboarders as it reveals a remarkably active pattern ahead, with multiple snow systems targeting key regions across the United States over the next two weeks. According to the analysis, a clipper-dominated pattern bring frequent snowfall opportunities to the Northern Plains, Midwest, Great Lakes, Ohio Valley, and interior portions of the Mid-Atlantic and Northeast through late December. While coastal areas may see less action, interior regions are positioned to see significant snowfall.
Clipper Train Rolls Through
The pattern becomes particularly active midweek, with multiple clipper systems forecast to march across the northern tier. A significant system on Tuesday will affect the upper Midwest and Great Lakes, eventually reaching the Northeast. Another clipper follows immediately behind on Thursday, December 11th, diving slightly further south with increased energy over the Rockies, Plains, and Midwest.
The Friday timeframe shows potential for something more significant. Model guidance suggests an opportunity for a coastal low to develop, which could bring a full-scale eastern snow system. The setup appears to favor ample cold air and possible southern stream moisture tapping into Gulf moisture.
Arctic Blasts on the Way
Temperature-wise, multiple Arctic air masses will sweep across the eastern United States. The first arrived earlier this week, with a second, more intense blast arriving later this week into the following weekend. Model guidance shows very cold conditions persisting through mid-December, with frequent reinforcing shots of Arctic air.
The forecast shows below-average temperatures dominating the eastern half of the country through at least December 20th, while warmer conditions develop across the West, indicating a positive PNA pattern.
Why Not Massive East Coast Storms?
While the pattern favors frequent snow, the setup isn’t ideal for huge coastal storms. The positive PNA pattern, though present, isn’t strongly amplified, resulting in a flatter trough over the East. The southern jet stream remains positioned too far south, explaining why clippers dominate rather than major nor’easters.
However, several timeframes around December 14th-17th and again near December 20th show potential for better phasing, which could bring more significant coastal snowfall opportunities for the Mid-Atlantic and Northeast.
Bottom Line for Snow Lovers
For skiers and snowboarders eyeing resort conditions, this pattern strongly favors interior mountain locations from the Rockies through the Great Lakes and into New England’s higher terrain. Frequent systems mean consistent powder refreshes, though individual storm totals may remain modest.
European and GFS model guidance both show impressive snowfall totals for the Midwest, Great Lakes, Ohio Valley, and interior Northeast through the forecast period. The northern Rockies and Cascades will also see substantial precipitation, much of it falling as snow at elevation. While coastal areas may see periodic systems, the most reliable action remains inland where cold air is never in question and clipper systems can consistently deliver fresh snow.
