"Northern Rockies & Pacific Northwest: Cooler than normal temperatures are favored across northern Washington, Idaho, Montana, and into the northern Great Plains. This colder pattern fits with ongoing La Niña and an active Madden-Julian Oscillation (MJO) phase that encourages cold air intrusion. Sierra Nevada & Great Basin: Forecast confidence is lower here, with models showing "equal chances" in parts of California and Nevada. An active MJO could swing early‑month temperatures cooler than average, especially in higher elevations."
"Northern Plains, Great Lakes, and Northern New England: Below‑normal temperatures likely, especially if a sudden stratospheric warming (SSW) event unfolds. Expect stronger intrusions of Arctic air in early and mid‑month. Southern Tier (California to the Southeast): Widespread warmth favored from southern California through the Gulf Coast into the Southeast and Mid‑Atlantic, with 50%+ probabilities for above‑average temperatures."
Colder-than-normal temperatures and good snow chances are favored across the Pacific Northwest, Northern Rockies, and Great Lakes, benefiting northern and high-elevation resorts. Ongoing La Ni n conditions and an active Madden-Julian Oscillation (MJO) support increased cold-air intrusions and early-month cooling in some areas. Sierra Nevada and Great Basin show lower forecast confidence with equal chances in places, though higher elevations could turn cooler briefly. The Southwest and much of the southern tier are expected to be warmer and drier overall, with only short, less-sustained cold snaps possible. North Slope and western interior Alaska are forecast warmer than normal.
