Forecast From Direct Weather: Another round of snowfall is on the horizon, with significant weather patterns setting up across the Rockies and beyond. The Rockies and Cascades continue to experience heavy snowfall driven by a mix of milder air to the west and cold air sweeping in from the east, creating instability. This pattern is expected to persist, with a potential shift into a more nor’easter-like system as we approach Monday, December 2nd.
A massive nor’easter is forecast to develop along the Carolina coast, bringing heavy snowfall to the Great Lakes, Ohio Valley, Mid-Atlantic, and Northeast. The system’s exact trajectory remains uncertain, particularly if the low-pressure center shifts offshore, which could significantly intensify impacts. Snowfall will likely be concentrated in higher elevations and interior areas, though details beyond 300 hours should be viewed with caution.
The northwest remains under a barrage of storms, with above-average precipitation spreading to the Plains, Midwest, and now much of the East. This pattern marks a significant uptick in moisture for many regions, signaling potentially substantial snowfall accumulations. The West is forecasted to receive immense amounts of snow, with three to six feet or more expected in the Cascades, Sierra Nevada, and Rockies. While models may overestimate totals, multiple feet of snow seem likely for these areas.
The Northern Plains and Upper Midwest also appear set for one to two feet of snow from successive storms, though the odds of every modeled storm materializing are low. In the Northeast and Mid-Atlantic, particularly in mountainous regions like the Catskills, Adirondacks, and White Mountains, snowfall potential is increasing but remains slightly lower than for the Plains and Midwest, which historically see more snow this time of year.
Temperatures will fluctuate, with brief warm spells followed by significant cool-downs expected to persist through the week. As the cold pattern solidifies, snowfall chances are likely to rise, especially in regions accustomed to early-season storms.
