25 Jan '26

Good morning everyone, Here is the latest update on the winter storm that is on our doorstep. Confidence is high that this will be a high impact snowstorm for the region. While snowfall amounts have been adjusted upward in northern and higher terrain areas, the message remains the same: many locations will see the most snow they've seen in many years with a window of very hazardous travel conditions from Sunday afternoon through the predawn hours Monday. Please don't hesitate to email us or pick up the phone and give us a call if you'd like to talk to a forecaster.

by BOX Operations - NOAA Service Account 24 Jan '26

24 Jan '26

Good afternoon, Attached is our latest briefing regarding Sunday/Monday's coastal storm. The forecast has continued to hold steady for the most part, aside from totals in northern MA being reduced into the 12-18" range. Totals in NE MA may end up in the higher end of that range. Confidence remains moderate regarding snowfall amounts over the south coast and into the Islands due to the chance for mixed precipitation moving in primarily towards the end of the storm Monday. If you have any questions, please don't hesitate to reach out. Thank you, Meteorologists Candice Hrencecin, Joseph Dellicarpini, Torry Dooley, Andrew Loconto and Francis Tarasiewicz If you have any questions or would like more information, please don't hesitate to contact us.

NWS Boston EM Briefing
by BOX Operations - NOAA Service Account 23 Jan '26

23 Jan '26

Good Afternoon Everyone, Attached is the latest briefing on the upcoming winter storm Sunday into Monday. The forecast has not changed significantly and because of high confidence, we have issued Winter Storm Warnings for all of southern New England. There is still some question as to whether or not snow will mix with, or change to sleet for a time near the South Coast, which would slightly lower snowfall totals in those areas. The next briefing will be sent by email early Saturday morning. Thanks, NWS Boston If you have any questions or would like more information, please don't hesitate to contact us.

[01.23.2026 AM] NWS Boston EM Briefing for Bitter Cold and Sunday-Monday Winter Storm
by BOX Operations - NOAA Service Account 23 Jan '26

23 Jan '26

Good morning everyone, You'll find attached our latest thinking on this weekend's impactful snowstorm expected Sunday into early Monday. This includes our initial “most likely snowfall accumulation” map. Keep in mind, this can and will be refined/changed as things come into better focus over the next 24-48 hours. One of the more pressing questions is how much any mixed precipitation (ice) on the south shore might bring down snow totals. The most likely timing of heaviest snowfall (1+ inch/hour) looks to be between 5PM and 11PM. If you have any questions, don't hesitate to reach out. Thank you, Bryce Williams If you have any questions or would like more information, please don't hesitate to contact us.
