09 Feb '24

All, We wanted to provide you with our latest thoughts for a Winter Storm we expect to impact southern New England late Monday through Tuesday. There is still considerable uncertainty with the forecast track of the storm, so exactly what we get for snow and/or rain is still unknown. Please see the attached 1-Pager briefing which summarizes our current forecast. We expect to be working out the details over the weekend as we gain more clarity into how the storm will evolve. Also attached are 3 images: 1) The current probability of getting at least 3 inches of snow. 2) The current probability of getting at least 8 inches 3) The current probabilities of seeing moderate level impacts per the Probabilistic Winter Storm Index We encourage you to use these websites to access weather information over the weekend to see how the forecasts are evolving.

[2024.01.28 PM] Mixed Precipitation And Accumulating Snow Tonight into Monday
by BOX Operations - NOAA Service Account 28 Jan '24

28 Jan '24

Good afternoon everyone, No major adjustments with our latest update. The Winter Storm Warnings and Winter Weather Advisories remain the same. The same is true for the Gale Warnings. Still mainly snow across the higher terrain. Elsewhere, mixed precipitation changes over to snow late tonight into Monday. The only exception is across the Cape/Islands where we change over to snow on Monday. We've attached a model simulated loop to give a rough idea on when the transition over to snow occurs, and when precipitation ends. Barring any significant changes to the forecast, this is the last briefing for this event. Please see the attached briefing and supporting graphics for more details. Thanks, Bill Leatham, Matthew Belk and Torry Dooley If you have any questions or would like more information, please don't hesitate to contact us.

[2024.01.28 AM] Mixed Precipitation And Accumulating Snow Today into Monday
by BOX Operations - NOAA Service Account 28 Jan '24

28 Jan '24

Good morning everyone Not too many changes have been made to the going forecast. Greatest impacts today will be across the higher terrain where temps will be a few degrees colder allowing for snow to accumulate more efficiently. In the lower elevations, some snow accumulations are possible today if precipitation falls heavy enough to change mixed precipitation to a period of all snow. A lull in the activity this evening with much of the precipitation being in the form of rain except for the high terrain. Colder air moves back into the region late tonight into Monday AM...which will allow mixed precipitation to change back to all snow and continue into Monday. This is especially true across central and eastern Massachusetts. The Monday morning commute will be impacted. Winter Storm Warnings are posted for the high terrain of the northern Berkshires and the northern Worcester Hills for total snow accumulations of 4 to 8 inches through Monday. Across the lower elevations, mixed precipitation will keep snow accumulations generally in the 1 to 4 inch range through Monday. Attached is our one-pager, along with a graphical image of our expected snow accumulations through Monday and Winter Weather Headlines. Please let us know if you have any questions or concerns. Meteorologists: Hayden Frank and Kyle Pederson If you have any questions or would like more information, please don't hesitate to contact us.

[2024.01.27 AM] Coastal Storm and Accumulating Snow Potential Sunday into Monday
by BOX Operations - NOAA Service Account 27 Jan '24

27 Jan '24

Good morning, The Winter Storm Watch has been expanded to much of northern and central MA. Snow totals have been bumped up slightly across the high terrain where confidence in snow accumulations are highest. There remains uncertainty in snow accumulations in lower elevations due to marginal temperatures and potential for mixed precipitation.

[2024.01.26 PM] Coastal Storm and Accumulating Snow Potential Sunday into Monday
by BOX Operations - NOAA Service Account 26 Jan '24

26 Jan '24

Good afternoon, Following is an initial one-page weather briefing and supporting graphics regarding a coastal storm that has the potential to bring accumulating snowfall to Southern New England Sunday into Monday. Winter Storm Watches have been issued for Sunday into Monday for the Berkshires, northern Worcester County and northwest Middlesex Counties. As mentioned in a previous e-mail sent this afternoon, mainly snow is expected for the duration in the higher elevations and the greatest potential for highest snow accumulations are currently anticipated here. In the lower elevations and along the coastal plain, due to borderline temperatures and onshore winds, rain may mix in with the snow before changing over to snow as colder air returns southward. Snow accumulations are subject to further adjustment, particularly in the lower elevations due to the two above factors. Given those two sources of uncertainty - we are including the latest official snow forecast but also a reasonable worst-case snow accumulation. This provides an idea of the kind of accumulations we could see if colder air supporting a changeover from rain to snow happens sooner. We do expect impacts to travel Sunday into Monday in the higher terrain, and mainly Sunday night and Monday as rain changes over to snow for the lower elevations. Impacts to the Monday commutes are anticipated. Attached graphics include a one-page briefing, our current official snow forecast, the reasonable worst-case accumulation, and the active winter weather headlines in effect. Expect our next briefing to be sent by 6 AM Saturday. Thank You! Meteorologists: Andrew Loconto and Frank Nocera If you have any questions or would like more information, please don't hesitate to contact us.

[2024.01.26 Early PM] Update on Accumulating Snow Potential Late Sunday into Monday
by BOX Operations - NOAA Service Account 26 Jan '24

26 Jan '24

Good afternoon, With it being later on Friday, we wanted to send a short e-mail regarding our latest expectations for a storm system that has the potential to bring accumulating snows to Southern New England later Sunday into part of Monday. We expect this storm system to feature mainly snow for the interior and higher terrain, while lower elevations such as the coastal plain may feature a rain/snow mix before changing over to snow. Overall this event looks roughly similar to those winter weather events we've had to this point in the winter - where the higher snow accumulations are expected to have a significant elevational component. In lower elevations, snow amounts are more uncertain due to temperatures being more borderline. We are still in the process of finalizing the forecast and details, but we are considering Winter Storm Watches for the Berkshires, along with portions of Worcester and Middlesex Counties where the best potential for snow amounts of 6 or more inches exists. With that said, some adverse impact to the Monday morning commute - even in lower elevations - looks reasonable. There are no attached graphics with this e-mail, but expect a follow-up e-mail briefing out no later than 6 PM today. Thank You! Meteorologists: Andrew Loconto and Frank Nocera If you have any questions or would like more information, please don't hesitate to contact us.

NWS Boston EM Briefing: Freezing Rain Potential Has Diminished This AM, But Rain Changing to Accumulating Snow Remains Possible Sun into Mon
by BOX Operations - NOAA Service Account 26 Jan '24

26 Jan '24

Good morning everyone The threat for freezing rain has diminished across much of the high terrain this morning with temperatures generally above freezing. There still could be some very localized light icing in the highest terrain of the northern Berkshires...mainly above 1500 feet where a Winter Weather Advisory remains in effect. There may actually be a better chance for pockets of light freezing drizzle/black ice across the high terrain of Massachusetts later tonight into early Saturday morning as temperatures are expected to be a few degrees colder. Otherwise, the main concern continues to be the expected coastal storm bringing the potential for rain to change to accumulating snow Sunday into early Monday. Greatest risk for a plowable snowfall will be in the higher terrain where temperatures will be colder. Across the rest of the region, snow accumulations are highly uncertain and will depend upon how quickly rain changes to snow and exact temperatures. We will have more details on this potential storm later today. Please let us know if you have any questions!
