What is new: - Winter Storm Warnings are in place north of the I-90/along the I-495 corridor - Winter Weather Advisories are in place across northern CT, northern RI, and much of MA south of I-90, excluding far SE MA, Cape Cod, and the Islands - High Wind Warnings are in place for Essex and Barnstable Counties - Wind Advisories are in place along the eastern MA coast - Coastal Flood Advisories are in place for the Islands and southern RI.

Good morning, Attached is the latest one page briefing and supporting graphics regarding a winter storm that is expected to impact southern New England late tonight into tomorrow morning. Confidence continues to grow that there will be moderate impact snow accumulations north of the I-90 corridor especially along and north of route 2. Little changes have been made to the snowfall forecast since yesterday's briefing, but we have made the following headline changes. - Winter storm watch has been upgraded to a winter storm warning for the areas north of I-90 away from the coast - Winter weather advisory in effect for Suffolk, Middlesex, and Essex counties east of the I-95 corridor, as well as the areas south of I-90 and west of I-495 away from the coast - Wind advisory in effect for east coast, Cape, and The Islands Timing for the system has slowed down by about an hour two which has further enhanced our confidence that impacts will not begin until AFTER the Friday evening commute. Animations of estimated timing for snowfall rates and precipitation type are attached. We will provide a final briefing later this afternoon. If you have any questions in the meantime please don't hesitate to reach out.

Good Afternoon All, Please find the latest briefing, regarding the potential for accumulating snow Friday night into Saturday, attached. Note that confidence has increased regarding impacts north of the I-90 corridor, with the highest confidence in impactful accumulations of snow north of Route 2 where more than 6" of snow is forecast to fall. A Winter Storm Watch has been issued for portions of Massachusetts north of I-90 and west of the I-495 corridors. Wind will also be of concern along the eastern MA coastline, where winds gusting between 40-50mph are likely on Saturday. While easterly winds will be strong, coastal flooding is not a concern as we will have low astronomical tides this weekend. Confidence in snow totals is lowest across the eastern MA coastline and south of I-90 as mixed precipitation such as sleet and rain will mix in after sunrise on Saturday. We would like to emphasize that the general timing of this system has not changed, with all impacts expected AFTER the Friday PM commute. Please let us know if you have additional questions.

Little has changed since yesterday's briefing. A bulleted summary of some of the changes is listed below. - Liquid precipitation forecast has increased and thus snowfall totals have increased slightly over the high terrain - Confidence is growing in the need for winter headlines for the interior zones along and north of the I-90 corridor. - Advisory and/or watch headlines may be issued as early as this afternoon.

Good afternoon, Please find our latest update regarding the accumulating snow potential late Friday night-Saturday morning attached below. We would like to emphasize that precipitation is not expected to begin until AFTER the Friday Evening commute. Additionally, confidence in accumulating snow is highest north of the I-90 corridor, with the greatest risk for accumulations in excess of 6" most likely above 600ft in elevation north of the Rte 2 Corridor. Travel impacts are expected to be limited south of the MA Turnpike, as temperatures will remain near or above freezing overnight. Minor shifts in the exact track of the system will result in changes to the potential for accumulating snowfall. We also anticipate that winds in excess of 40 mph will affect the eastern MA coastline, with winds gusting over 50 mph possible, especially across the Cape and Islands. A gale watch is currently in place for the waters. Mariners should be aware that storm warnings may need to be considered for a large portion of Saturday. While we do not currently have winter weather headlines in place for this system, it is likely that they will be considered over the next 24 hours. Please do not hesitate to reach out with any questions.

Good morning, We wanted to begin messaging for a potentially impactful winter storm that will impact the Northeast Friday afternoon into Saturday. Attached is a one page briefing with some details on where the forecast stands at this point in time. Confidence is growing that there will be at least minor impacts for the areas north of I-90. The attached graphic represents the percent chance of 24 hour snowfall exceeding 4 inches. We'll have more details over the next 24 hours as new data becomes available. Additionally, since we are sending this email we wanted to provide a heads up that there is also a chance for some spotty freezing rain showers tonight over the high terrain of The Worcester Hills and The Berkshires. Given the expected isolated/spotty nature of these showers, there is no winter weather advisory in effect for freezing rain. There will however be the potential for a few slick spots over these areas, but little to no impacts are expected.
