Meteorologist Danielle Noyes here with the “why” behind the forecast. The next two weeks feature a fast-changing pattern: a brief midweek warm-up, a quick blast of cold by Friday, a near-seasonable weekend (Jan 17–18), and then another, stronger push of colder-than-average air late month that likely lingers into early February.
A ridge nudges warmth into New England through midweek, then a cold shot arrives Friday. We moderate back to near normal over the weekend before a broader, longer cold stretch returns for the last week of January into early February. Expect daytime highs to swing from above average midweek to below average late month, with overnight lows frequently in the teens (and single digits at times in northern New England).
The jet stream turns a bit more amplified, then gradually flattens to a faster west-to-east (“zonal”) flow – with more classic “clipper-type” systems
Fri (lingering): Watching the departing system’s exact timing/track.
Sat night–Sun: A quick-moving wave; details still in flux but worth monitoring.
Jan 23–26: Multiple disturbances in a colder pattern; track will determine how far south meaningful snow reaches.
Over the next ~10 days, the nation looks relatively quiet outside the Pacific Northwest and the Southeast, while the Great Lakes to northern New England run nearer/slightly above normal precipitation. With colder air reasserting late month, northern New England has strong consensus for 1–2 feet of snow over the next 10 days, with lesser amounts south. South of the mountains, totals will hinge particularly on the Jan 23–26 window.
