by BOX Operations - NOAA Service Account 27 Dec '18

27 Dec '18

Good morning, We continue to forecast a wintry mix of snow, sleet and freezing rain tomorrow (Friday) morning. The Winter Weather Advisory has been expanded to include northern Connecticut, central/eastern Massachusetts, and northern Rhode Island. Highest confidence of ice accumulation continues to be focused on the Berkshires and Worcester Hills, but all of these areas could see a period of icy conditions. This system will impact the Friday morning commute and transition to an all rain event. *What:* - A mix of snow, sleet, and freezing rain changing to rain. - Light snow accumulations w/ a glaze of ice causing slippery conditions on area roadways. - Risk for impact to the Friday morning commute. *Where:* - Interior MA, CT, and RI, especially the higher terrain of western and central Massachusetts and Connecticut *When:* - 1 am to 10 am Friday. 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>

[2018.12.26 PM NWS Briefing] Wintry Mix Comprising of Freezing Rain across N/W MA Friday Morning
by BOX Operations - NOAA Service Account 26 Dec '18

26 Dec '18

Good afternoon, We continue to forecast a wintry mix of snow, sleet and freezing rain for Friday morning. With the threat of freezing rain, WINTER WEATHER ADVISORIES have been posted for northern and western portions of Massachusetts, mainly focused on the Berkshires and Worcester Hills where we have the highest confidence of ice accretion. Further details below. *What / Where / When ... * - A wintry mix of snow, sleet and freezing rain is forecast Friday morning, roughly 4 am to 10 am, before transitioning to all rain - Mainly across northern and western portions of Massachusetts - Especially at higher elevations of the Berkshires and Worcester Hills - A coating upwards of around an inch of snow and/or sleet, along with a glaze of ice is forecast - Expected impacts to the AM commute as surfaces will become slick and there will be reductions in visibility leading to hazardous travel conditions - Again, Winter Weather Advisories posted, mainly focused on the Berkshires and Worcester Hills. These may need to be adjusted with later forecasts as we continue to iron out the freezing rain threat. - Though not entirely confident, the associated storm system delivering wintry weather impacts as outlined above will also bring a decent slug of rain along with some gusty winds for S/SE portions of New England - Rainfall amounts up to around an inch, there is the localized possibility of some nuisance flooding with poor drainage issues, ponding of water along area roadways - Potential gusts up around 40 mph, can't rule out some isolated wind damage. Main focus is along the immediate S/SE coastline of Rhode Island and Massachusetts. Biggest concern is with regards to any holiday decorations becoming airborne. Should you have any questions, comments and/or concerns, please do not hesitate at any time to reach out to us. There will be later briefings leading up to the event, the next one scheduled for 5 am Thursday. Respectfully, Benjamin Sipprell Meteorologist NWS Boston / Taunton 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>

Normally the magnitude of the upcoming event wouldn't warrant an email, but since it's Christmas Eve and there's a bunch of traveling going on, thought we'd send a heads-up. A weak storm will pass well to our south early Monday. Light snow is expected to accumulate up to 1 to 1.5 inches in a portion of northern CT and in the slopes of the Berkshires beginning around 4 AM and lasting into the mid-morning Monday. Some light snow could also spread across the remainder of the region around daybreak, but it will taper off during the morning with little accumulation in RI, eastern MA, or northeastern MA. Temperatures will climb to the mid/upper 30s Monday, melting most or all of the snow. Another strong upper level disturbance will cause a chance of light snow or snow showers, mainly in northeastern and eastern MA, early Monday evening. Another dusting to less than an inch is possible there. Clearing after midnight. Much ado about a dusting to up to 1.5 or 2 inches of snow in a few spots. Happy holidays, everyone. -- Glenn Field WCM, NWS - Norton, MA 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>

by BOX Operations - NOAA Service Account 21 Dec '18

21 Dec '18

Good morning everyone, Included with this email is the latest, and possibly final briefing update for the storm expected today into this evening. Overall, the forecast remains similar regarding the expectation of heavy rain and coastal flooding. At this time, it looks like the best chance for final rainfall totals exceeding 3 inches is across W MA and CT. We have expanded the High Wind Warning and Wind Advisories further west. The High Wind Warning (risk for 50-60 mph gusts) now includes south coastal Rhode Island and Massachusetts. The Wind Advisory now includes northeastern Connecticut, northwestern Rhode Island and central-eastern portions of Massachusetts that were not included with last evening's update. The primary heavy rain for western areas will be through the afternoon, then this afternoon and evening further east. The strongest winds are expected from about mid morning into the evening, with a peak during the evening hours. The risk for south coastal flooding will occur with this evenings high tide. As always 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>

NWS Boston/Norton PM Storm Briefing
by BOX Operations - NOAA Service Account 20 Dec '18

20 Dec '18

Good afternoon everyone, The latest briefing for the upcoming storm is attached. *Changes:* - High Wind Warnings has been issued for Cape Cod and the Islands, and Wind Advisories are being issued for much of Rhode Island and eastern Massachusetts. - Coastal Flood Advisory has been issued for south coastal Rhode Island and Massachusetts for the Friday evening high tide. - Storm Warnings have been issued for most of the Massachusetts coastal waters. - The heaviest rainfall, 2 to 3 inches on average with locally as much as 4 inches, is now expected across western and central Massachusetts and northern Connecticut. This is where the highest risk of minor river flooding exists. Some of the smaller rivers in these areas could reach moderate flooding, but that is highly dependent on how much rain falls. Confidence remains high in expected impacts from heavy rain, high winds, and coastal flooding, starting late tonight and lasting into Friday night. Keep in mind flooding on main stem rivers may not occur until this weekend, especially on the Connecticut River. 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 by phone at 508.622.3280 Thanks, Joe DelliCarpini NWS Boston/Norton

[2018.12.20 AM NWS Briefing] Multi Faceted Storm Begins Late Tonight
by BOX Operations - NOAA Service Account 20 Dec '18

20 Dec '18

Good morning everyone, We continue to monitor a developing storm system which will begin to impact the region late tonight. The primary issues continue to be heavy rainfall, strong winds and a risk for minor coastal flooding, especially along the south coast. Rain will overspread the region late tonight, and winds will begin to increase. Rain and modest wind gusts will impact the morning commute Friday. The strongest winds and heaviest rainfall is expected during the day Friday and into Friday evening, impacting the evening commute. As for the coastal flood risk, the astronomical tide is highest early Friday morning, however winds and surge will be limited. The late afternoon/evening tide is lower, but surge, seas and winds will be stronger by that point. We will continue to monitor and update as we get closer. - NWS Boston/Norton If you have any questions or would like more information beyond the scope of this briefing, 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>

Strong storm system late Thursday night into Friday night
by BOX Operations - NOAA Service Account 19 Dec '18

19 Dec '18

Hi everyone, Here is the latest information for the upcoming storm. 1) A Flood Watch has been issued for all of southern New England from late Thursday night through late Friday night. Rain starts late Thursday night but the heaviest rain will occur during the day Friday and into Friday night. We are expecting a widespread 2 to 3 inches of rain except 1 to 2 inches on Cape Cod and the islands. There could be up to 4 inches in portions of western MA, northern CT, and western RI. Currently 1 to 2 inches is forecast for Cape Cod and the Islands. Urban and poor drainage flooding is expected. Small streams and creeks could also flood. There is a possibility that a few main stem rivers could rise to minor to perhaps moderate levels. 2) A High Wind Watch has been issued for Cape Cod, Nantucket, Martha's Vineyard, and Block Island from Friday morning through Friday evening. Southeast to south winds of 25-35 mph are forecast with gusts to 50 mph. However, the potential exists for gusts up to 60 mph. The latest indications are that the strongest winds may occur a bit later, perhaps in the late afternoon through midnight Friday night. Wind Advisories will likely be needed farther inland into the coastal plain and possibly atop higher elevation locations. 3) Gale Watches have been upgraded to Gale Warnings for all coastal waters from early Friday morning through much of Friday night for wind gusts to 45 knots. 4) Coastal Flooding: The south coast continues to be the main focus for possible minor coastal flooding on Friday, although with astronomically high tides we may also see at least some splashover but possibly minor coastal flooding along the eastern MA coast, too. A surge of up to 2 feet is expected. We could see minor coastal flood impacts along the south coast from Narragansett Bay to Buzzards Bay -- possibly along the rest of the south coast due to wave action. With only 1 foot of surge, the more vulnerable locations on the Massachusetts east coast, like Morrissey Blvd., could be flooded during the Friday and Saturday morning high tides. 5) Severe weather potential: A few thunderstorms are possible in RI and southeastern MA. Conditions will be quite anomalous with 60-80 knots of wind just a few thousand feet off the surface, with record high dewpoints near 60 degrees and actual temperatures reaching the lower 60s in those areas. Certain other parameters are in place to make us concerned for the possibility of an isolated waterspout or tornado in RI or southeast MA. It is a quite low probability but if it were to occur, the most likely time would be Friday afternoon. The greatest uncertainties with this event are: * timing of heaviest rain and strongest winds * location of heaviest rain This event is still more than 30-36 hours away, so stay tuned for any further updates. -- Glenn Field Warning Coordination Meteorologist NWS - 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>
