Good morning everyone, The latest briefing for the weekend storm is attached. Please note the following changes: - *Minor adjustments to snow and ice totals. * - *Winter Storm Warning issued for Berkshire County MA and Litchfield County CT.* Our confidence remains moderate to high for a period of freezing rain across CT, RI, and southeast MA and for sleet (as opposed to all snow) across much of the region. Uncertainty remains with respect to how much precipitation falls as freezing rain or sleet. The window of greatest concern for sleet and freezing rain is between 2 AM and 5 PM Sunday.

[2018.01.17 AM NWS Brief] 2 Systems To Monitor Through This Weekend
by BOX Operations - NOAA Service Account 17 Jan '19

17 Jan '19

Good morning everyone, We continue to monitor two winter systems, one for early Friday, the other for the weekend. * Note that the single snowfall forecast attached to this email is for the Friday morning system only. The full set of briefing slides is for the weekend storm.* *Friday:* - Light snow begins between 1 AM and 7 AM Friday, impacting the commute for most of Southern New England. - Snowfall rates of less than 1 inch/hour are expected, with accumulations up to 2 inches across western MA, decreasing closer to the coastlines. (See attached snowfall map) - Snow changes to rain, especially across the coastal plain of MA/RI during the afternoon. - Some untreated road surfaces may be covered. *Saturday night - Sunday night:* See the slides attached to this email. Heavy snow changing to an icy mix and then to rain, mainly across the southeast, is expected, along with a risk for strong winds, inland and coastal flooding. This storm is likely to be followed by a flash freeze beginning late day Sunday into Sunday night, with bitter cold air into Monday. *Be aware*, *the snowfall totals for the weekend storm are likely to evolve over the next couple of days. Note the rather large range in accumulation between the best and worst case scenarios. These are being provided now as a first look. Sleet accumulation has been added into the "snow" total accumulation.* Overall confidence is high for a moderate to high impact storm, but confidence in exact details and timing remains low at this time. We will continue to update into this weekend. If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or at the following: National Weather Service Boston/Norton, MA 46 Commerce Way Norton, MA 02766 508.622.3280 Website <http://www.weather.gov/boston> | Facebook <http://www.facebook.com/NWSBoston> | Twitter <http://www.twitter.com/NWSBoston>

[2018.01.16 AM NWS Briefing] 2 Systems To Monitor Through This Weekend - Correction
by BOX Operations - NOAA Service Account 16 Jan '19

16 Jan '19

Good morning, all: Just a quick correction to our prior message to include the header for the Friday section for clarity. No other changes have been made. We apologize for the oversight. *Friday:* - Light snow will overspread from west to east during the morning commute. Snowfall rates should generally be light, at or below an inch an hour. - The light snow will continue, with accumulations of up to 3 inches, ending during the late afternoon and evening. Highest totals across northern and western MA/CT, lowest totals across RI and eastern MA. - A change to rain is expected across the coastal plains of MA and RI during mid day into the afternoon. - Some light accumulations possible on untreated surfaces. A preliminary graphic is attached. *Saturday night - Sunday:* - Low confidence in the details at this time. - Precipitation will begin late Saturday evening, overspreading the entire area Saturday night into mid day Sunday. - Tricky precipitation type forecast, potentially starting as period of heavy, wet snow, changing to ice then to heavy rain into the day on Sunday. Timing of these changes will likely take a couple more days to resolve well. - There is a risk for a significant, plow-able snowfall and/or icing. - There is also the low-moderate risk for some areal and river flooding given the snow to rain transition. - We are monitoring the risk of coastal flooding along the South Coast. The period of concern is short, the potential is for minor flooding at worst, and the risk remains low. We will continue to update you as this week progresses and confidence increases. If you have any questions or concerns beyond the scope of this briefing, don't hesitate to reach out to us via any of the means below. - NWS Boston/Norton If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or at the following: National Weather Service Boston/Norton, MA 46 Commerce Way Norton, MA 02766 508.622.3280 Website <http://www.weather.gov/boston> | Facebook <http://www.facebook.com/NWSBoston> | Twitter <http://www.twitter.com/NWSBoston>

Freezing Drizzle/Light Freezing Rain Threat Northwest of Boston to Providence Into This Evening
by BOX Operations - NOAA Service Account 08 Jan '19

08 Jan '19

Good morning everyone This is just a very brief outline concerning areas of freezing drizzle/light freezing rain threat to the northwest of the Boston to Providence corridor into this evening. There also is the potential for Wednesday morning snow, mainly across the interior high terrain along the east slopes of the Berkshires and Worcester Hills. *WHAT/WHERE/WHEN: * - Areas of freezing drizzle will remain possible through the afternoon to the northwest of the Boston to Providence corridor. - Steadier rain/freezing rain overspreads the region between 5 and 9 pm this evening. Greatest concern for freezing rain will be across portions of the CT River Valley, into central and northeast MA. - We will need to keep a close eye on northeast MA, especially Middlesex and Essex counties. Temperatures may temporarily rise above freezing, but fall back into the upper 20s to the lower 30s later this afternoon and evening, resulting in icy conditions developing. - *Untreated roads/walkways may already be or become icy to the northwest of the Boston to Providence corridor. Evening rush hour may be impacted.* - There is a low risk that sub-freezing temperatures move back even into the Boston metro area for a time this evening, resulting in the development of icy conditions. - Lastly, there may be a burst of snow Wednesday morning across the higher terrain of MA with an impact to the am rush hour possible. This would mainly be across the east slopes of the Berks and perhaps portions of the Worcester Hills. We will have more on this later in the afternoon, but a few inches are possible especially along the east slopes of the Berks. Please let us know if you have any questions or concerns. Thank You Meteorologist: Hayden Frank If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or at the following: National Weather Service Boston/Norton, MA 46 Commerce Way Norton, MA 02766 508.622.3280 Website <http://www.weather.gov/boston> | Facebook <http://www.facebook.com/NWSBoston> | Twitter <http://www.twitter.com/NWSBoston>
