A northern jet stream disturbance moves in Saturday bringing a minor snowfall event to the region. While this isn’t a blockbuster storm, the setup involves some fascinating meteorology worth diving into!
A developing storm will pass well south of New England, but energy from the northern branch of the jet stream will swing through, introducing light snow to much of the area. Adding intrigue, we anticipate an inverted trough—a feature where disturbances extend northwest from a storm center—helping to prolong snow showers near the coast.
Snow begins early Saturday morning, between 4 and 7 a.m., for most of southern New England and later in the morning for Maine. By midday, snow tapers off in western New England but may regenerate in eastern areas due to the trough. Snow showers could linger into Saturday evening, especially along Cape Cod and the South Shore, where ocean enhancement may boost totals slightly.
For much of the region, snow amounts will be modest:
The combination of marginal temperatures and light snow intensity will limit accumulation. However, roads could become slippery during the morning and again after a refreeze Saturday night.
