Area Forecast Discussion National Weather Service Boston/Norton MA 257 PM EST Sat Jan 17 2026

WHAT HAS CHANGED

A winter weather advisory has been issued for all of CT and into much of Eastern MA and RI. Confidence has increased for 2-5 inches of snow across the advisory areas, with localized spots up to 6 inches possible in SE MA and RI. Confidence remains too low still for NW MA and for Block Island and Nantucket to be included in the advisory at this time.

KEY MESSAGES

- Snow continues across NW MA this afternoon, ending after 5pm this evening.

- Coastal low passes just SE of the Benchmark, bringing 2-5 inches with localized areas of 6 inches, especially in SE MA and RI.

- Arctic cold front pushes through Monday night bringing well below normal temperatures and bitterly cold conditions. The peak of this cold weather will be Tuesday into early Wednesday morning.

- Milder conditions arrive later Wednesday-Thursday, with perhaps a brief period of light snow showers or even light rain showers near the coast.

DISCUSSION
KEY MESSAGE 1...Snow continues across NW MA this afternoon, ending after 5pm this evening.

Snow begins to taper off across western MA this evening after 5pm as the mid level shortwave pulls away from the region and drier air. Additional accumulations across western Mass could reach 1-2 inches this afternoon. Snow transitions to rain as precip approaches the coastal plain as temperatures are currently above freezing through midnight.

KEY MESSAGE 2...Coastal low passes just SE of the Benchmark, bringing 2-5 inches with localized areas of 6 inches, especially in SE MA and RI.

An elongated shortwave trough stretching from the northern Great Lakes down into the Gulf Coast will spin up a coastal low offshore, passing just southeast of the benchmark. Guidance continues to come into Better agreement on track with this low, but remains spread on how far NW the QPF field extends. Guidance generally ticked up total QPF across the region with 1/2 to 3/4 inches across the Cape and Islands, and a 1/4 to 1/2 inch along and south of the I-95 corridor. How this translates into snowfall accumulation will depend heavily on temperatures and mid-level forcing. Temperatures during this event will be marginal, with temperatures staying near freezing inland and at or above freezing for the Cape and Islands.
This will impact snow totals as snow will melt and compress as it falls. Even areas inland will see very wet and heavy snow. Even where temperatures are above freezing, still anticipating accumulations for temps between 32-35F as strong mid-level forcing will allow for precipitation to become heavy enough to drag down cooler air and remain as snow rather than turning to rain.

The highest confidence in snow totals across the region is in SE MA and into RI, where strong mid-level forcing and temperatures near or below freezing will overlap. Snow totals in this area will range from 3-5 inches, with localized areas reaching 6 inches. While there will be good forcing over Nantucket and Block Island, temperatures will likely be too warm for significant accumulations, but a slushy inch remains possible. Across CT and into north-eastern MA, the mid- level forcing is not quite as strong, but lower temperatures will allow for 2-4 inches, with localized spots up to 5 inches.
Uncertainty is highest across NW MA, where a lack of mid-level forcing and dry air will limit totals. Still could see 1-3 inches, but if the low moves closer to the benchmark, these totals could increase, and the advisory could be expanded NW.

Timing this system out, A band of snow showers associated with the prefrontal wave moves into CT as early as 7 am, but most likely not arriving until after 10 am. Snow spreads north and east into the rest of the region after the lunch hour. Snow will initially start light with rates of under half an inch per hour. Heaviest snow rates arrive later in the afternoon and into the early evening, with rates between 1/2 inch and 1 inch per hour through 10 pm to midnight. Snow rates could exceed 1 to 1.5 inches per hour near the Cape and Far SE MA if temperatures are able to cool below freezing.
Snow ends from west to east between 10 pm and 2 am, snow showers may linger into Monday morning. Breezy winds are expected Monday afternoon behind the system, but given the wet and heavy nature of the snow, we do not anticipate blowing snow impacts on Monday.

KEY MESSAGE 3...Arctic cold front pushes through Monday night bringing well below normal temperatures and bitterly cold conditions. The peak of this cold weather will be Tuesday into early Wednesday morning.

High pressure across the southern USA should combine with a low pressure over the Saint Lawrence Valley to funnel significantly colder air into our region towards the middle of next week. Strong signals in the ensemble data, with temperatures some 2-3 standard deviations below normal. While not quite at the minimum of climatology, still looking quite cold, especially at night. Gusty winds Tuesday should lead to minimum wind chill values in the single digits around 0F Tuesday morning.

KEY MESSAGE 4...Milder conditions arrive later Wednesday- Thursday, with perhaps a brief period of light snow showers or even light rain showers near the coast.

Not anticipating quite as much wind into Wednesday as high pressure moves offshore of the Mid Atlantic coast, so some moderation in temperatures starts Wednesday. Winds turn more southerly ahead of a cold front, which is currently expected to move through some time Wednesday night into Thursday. Some light snow or rain showers could accompany this front. Colder air should return for late next week, with another period of below normal temperatures possible.
