[2019.12.02 10 PM] NWS Boston EM Briefing: Weather Hazards Thru Early Tuesday
by Glenn Field - NOAA Federal 02 Dec '19

02 Dec '19

Good evening everyone, Just a quick update... No changes to warnings. We have lowered expected snowfall totals just a tad based on some of the latest model information. Still have high confidence of 4 inches in eastern MA with areas of 6 to 8 inches possible. A slight shift to the west of the track of the storm could mean higher totals and a slight shift more offshore would mean lower totals. During the past two hours, four inches have fallen in a very heavy band over Windsor Locks, CT. The potential for similar banding exists toward daybreak in eastern MA. If a heavy band were to occur there, it would most likely be between 4 AM and 10 AM. Please see attached snow total graphic, from 7 PM this evening to 7 PM tomorrow evening. -- Glenn Field Warning Coordination Meteorologist NWS - Boston/Norton, MA

Resending the briefing package to include the subject header. Good afternoon, Here is our latest thinking on the next phase of the winter storm. *Watches/Warnings/Advisories:* NEW: 1) *Winter Storm Warnings* expanded to include coastal Essex, Suffolk, Norfolk and Plymouth counties. 2) *Winter Weather Advisory* issued for Cape Cod 3) *Wind Storm Warnings converted to Advisories *for western and northern MA west of I-495 *What we expect:* *Tonight into Tuesday morning* - Rain changing to snow across eastern MA through this evening with changeover occurring on Cape Cod toward daybreak - Bands of heavy snow possible across much of eastern MA, especially from 4-10 am. Localized snowfall rates of 1-2"/hour possible - Significant impacts to morning commute across eastern MA *Strong Winds:* - Wind gusts to 40 mph expected along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA. *Snow Accumulations:* - Additional accumulations after 7 pm tonight through Tuesday morning... - Generally 2-4 inches across much of the region, but up to 4-8 inches possible across eastern MA, especially from Boston north through Essex county and the Merrimack Valley. *Confidence* : - Moderate confidence in additional snowfall of 4 inches for eastern MA. Lower risk for up to 8 inches, especially north of Boston. - If storm tracks a bit further east than expected, lower snowfall amounts would be realized for eastern MA with max snowfall around 4 inches. - If storm tracks further west, 4-8 inches would impact a larger portion of eastern MA and possibly into northern RI, with locally higher amounts north of Boston. -- Kevin Cadima 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 02 Dec '19

02 Dec '19

Good morning everyone, Here is our latest thinking on the second half of the ongoing winter storm. *Watches/Warnings/Advisories:* NEW: 1) *Winter Weather Advisory* expanded to include Washington, Kent, SW Providence, Bristol, and Newport counties in RI; Bristol and Plymouth counties in MA 2) *Wind Advisory *for Cape Cod, Nantucket, and Martha's Vineyard through 1 PM. 3) *Coastal Flood Advisory* for eastern Essex and Plymouth counties and Nantucket this afternoon *What we expect:* *Today into early Tuesday* - Continued/ongoing snow in interior western/central MA will spread into eastern MA, northern CT and RI tonight. Lighter, more manageable snows expected in central and western MA and northern CT/RI. However, snow is expected to increase in intensity tonight into Tuesday across eastern and northeast MA, with 1-2"/hr snowfall rates possible in these areas. - Impacts to the Tuesday morning commute are possible. *Winds and Minor Coastal Flood Potential:* - Winds will gust to 40-50 mph along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA. - Storm surges of up to 2 feet are expected, but astronomical tides are low. A Coastal Flood Advisory has been issued for up to a foot of inundation above ground level possible for Eastern Essex, Eastern Plymouth, and Nantucket. *Storm Total Accumulations:* - In today's briefing we are showing only new snow expected today into Tuesday. We expect an additional 3-6 inches across the interior high terrain during the day today. By Tuesday morning interior locations can expect a Monday/Tuesday total of 8-12" with lesser amounts to the south and east. The heaviest snow may come Tuesday morning over far eastern MA. *Confidence* : - Confidence is moderately high for this second round of heavy snow Monday night/Tuesday period in eastern MA. How far west these snowbands extend is still uncertain, which could affect who sees those highest snowfall totals. -- Bryce Williams and Matthew Belk 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>

01 Dec '19

Good evening everyone, Here is our latest thinking on the upcoming significant winter storm just beginning to affect Southern New England, continuing to do so through early Tuesday. *Watches/Warnings/Advisories:* 1) NEW: Winter Storm Warning expanded to include Western Essex, Southeast Middlesex and Eastern Hampshire counties in MA for this evening. *What we expect:* *Changes:* Increased snow and ice amounts. Stressing two rounds of heavy snow: tonight into overnight interior MA/northernmost CT, and Monday night into Tuesday eastern/northeast MA. Other than western and central MA where lighter snows are expected to continue, mostly rain is expected elsewhere through late afternoon Monday. *Tonight into early Monday* - Snow becomes heavy at times (1"/hour) shortly after onset and continues into the evening hours. - Precipitation changes to sleet and freezing rain in northern CT, RI, to a sleet/snow mix in northern MA, and to plain rain in southern RI and southeast MA for the overnight hours. - By daybreak Monday, snow/sleet accumulations of 6-8" possible in western and northern MA with approximately 4-6" in Springfield and interior Essex County, with 2-5" elsewhere (including MetroWest Boston), except less than an inch on Cape Cod/Islands and near the immediate coast in southeast MA and southern RI. - The snow will be very moisture-laden. This could make for compact snow but it will be heavy to shovel. - Wind gusts will increase to 25-40 mph along the south coast late Sunday night. *Monday Night into early Tuesday* - Continued/ongoing snow in interior western/central MA will spread into eastern MA, northern CT and RI Monday night. Lighter, more manageable snows expected in central and western MA and northern CT/RI. However, snow is expected to increase in intensity Monday night into Tuesday across eastern and northeast MA, with 1"/hr snowfall rates possible in these areas. - Impacts to the Tuesday morning commute are possible. *Winds and Minor Coastal Flood Potential:* - Winds will gust to 35-45 mph along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA. - Storm surges of up to 2 feet are expected, but due to low astronomical tides, only splashover is expected for east coastal MA, including Cape Cod Bay and Nantucket (with northeast winds). Will keep a close eye on this as some pockets on minor coastal flooding cannot be ruled out. *Storm Total Accumulations:* - We are still expecting a widespread 8 to 12 inches over much of interior MA with as much as a foot possible in the higher Worcester hills and 12 to 17 inches in the east slopes of the Berkshires and into areas near/north of Route 2 into northeast MA. These snow amounts are for both periods of heavy snow combined. Amounts drop off rapidly as one heads southeast, with 3 to 5 inches from southern Hartford County eastward to Providence and Plymouth and less than an inch on Cape Cod and the Islands. *Confidence* : - Confidence is highest in the warning areas of western and northern MA, where >6" of snow in a 12 hour period or 8" in a 24 hour period is likely. Confidence decreases moving into I-495 and towards the coast, where east winds contributing to temperatures near or just above freezing become offset by heavy precipitation rates. - Confidence is moderately high for the second round of heavy snow Monday night/Tuesday period in eastern MA. How far west these snowbands extend is uncertain, which could affect snowfall totals in the Monday night to Tuesday period. -- Andrew Loconto/Frank Nocera 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>

Good morning everyone, Here are our latest thoughts on the upcoming significant winter storm impacting southern New England this afternoon through early Tuesday. *Watches/Warnings/Advisories:* 1) NEW: Winter Storm Warning now includes Western Hampden, Western Hampshire, all of Franklin, northern Worcester, and northern/central Middlesex counties in MA. 2) NEW: Winter Weather Advisory now includes Hartford, Tolland, and Windham counties in CT; northwest Providence County in RI; Norfolk, eastern Hampden, eastern Hampshire, southern Worcester, Suffolk, southeast Middlesex, and Essex counties in MA. 3) NEW: Gale Warning now in effect for all coastal waters from this afternoon through Monday afternoon/night. *What we expect:* Changes: Slightly lower snowfall totals from our last update and slower onset time today. *Sunday into early Monday* - Slower onset. Snow will begin in western MA between 2 and 3 PM Sunday; CT Valley and central MA 3-4 PM Sunday; and eastern MA 4-6 PM. - Snow becomes heavy at times (1"/hour) shortly after onset and continues into the evening hours. - As warmer air intrudes aloft, precipitation changes to sleet and freezing rain in northern CT, RI, to a sleet/snow mix in northern MA, and to plain rain in southern RI and southeast MA for the overnight hours. - By daybreak Monday, snow/sleet accumulations of 6-8" possible in western and northern MA with approximately 4-6" in Springfield and interior Essex County, with 2-5" elsewhere, except less than an inch on Cape Cod/Islands and near the immediate coast in southeast MA and southern RI. - The snow will be very moisture-laden. This could make for compact snow but it will be heavy to shovel. - Wind gusts will increase to 25-40 mph along the south coast late Sunday night. *Monday into early Tuesday* - Early in the morning, rain will be occurring in RI, portions of northern CT and much of eastern MA, with a mixed bag elsewhere. However, everything will change back to snow from west to east. The changeover will reach as far east as northeast MA, central MA, and northern CT by early to mid afternoon. It will reach RI and eastern MA (except Cape Cod/Islands) by mid afternoon into the late evening. The snow will likely continue into early Tuesday morning. Less snow is expected than what occurred on the front end Sunday, but there still could be several inches in some locations. This may be dependent on where localized bands of heavier snow set up. - Winds will gust to 35-45 mph along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA. - Storm surges of up to 2 feet are expected, but due to low astronomical tides, only splashover is expected for east coastal MA, including Cape Cod Bay and Nantucket (with northeast winds). Will keep a close eye on this as some pockets on minor coastal flooding cannot be ruled out. *Storm Total Accumulations:* - We are still expecting a widespread 8 to 10 inches over much of interior MA with as much as a foot possible in the higher Worcester hills and 12 to 17 inches in the east slopes of the Berkshires. Amounts drop off rapidly as one heads southeast, with 3 to 5 inches from southern Hartford County eastward to Providence and Plymouth and less than an inch on Cape Cod and the Islands. *Confidence* : - Confidence is highest in the warning areas of western and northern MA, where >6" of snow in a 12 hour period or 8" in a 24 hour period is likely. - Our lowest confidence is in southeast sections, particularly along the I-95 corridor. This could be a situation in which there is a sharp snowfall gradient within the city of Boston, with only a slushy inch or two at the immediate coast to warning criteria amounts in western Suffolk County. -- Matt Belk/Bryce Williams 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>

Good evening everyone, This e-mail update provides the PDF attachment for this briefing. All other details in this e-mail remain unchanged from 430 pm. Here is the latest information on the upcoming significant winter storm, which will begin tomorrow afternoon and end early Tuesday morning. *Watches/Warnings/Advisories:* 1) Winter Storm Warning continues for Western Hampden, Western Hampshire, all of Franklin, northern Worcester, and far northwest Middlesex Counties in MA 2) Winter Storm Watch continues for Hartford and Tolland Counties in northern CT; eastern Hampden, eastern Hampshire, southern Worcester, Norfolk, central and southeast Middlesex, Suffolk and Essex Counties in MA 3) NEW: Winter Weather Advisory now in effect for Windham County, CT and northwest Providence County, RI. 4) NEW: Gale Watch now in effect for all coastal waters from Sunday afternoon through Monday afternoon/night. *What we expect:* *Sunday into early Monday* - Snow will begin in western MA between Noon and 1 PM Sunday; CT Valley and central MA 1-3 PM Sunday; and eastern MA 3-5 PM. - Snow becomes heavy at times (1"/hour) shortly after onset and continues in the late afternoon and evening hours. - As warmer air intrudes aloft, precipitation changes to sleet, then freezing rain in northern CT, RI, to a sleet/snow mix in northern MA, and to plain rain in southern RI and southeast MA for the overnight hours. - By daybreak Monday, snow/sleet accumulations of 6-8" possible in western and northern MA with approximately 4-6" in Springfield and interior Essex County, with 2-5" elsewhere, except less than an inch on Cape Cod/Islands and near the immediate coast in southeast MA and southern RI. - The snow will be very moisture-laden. This could make for compact snow but it will be heavy to shovel. - Wind gusts will increase to 25-40 mph along the south coast late Sunday night. *Monday into early Tuesday* - Early in the morning, rain will be occurring in RI and much of eastern MA, with a mixed bag elsewhere. However, everything will change back to snow from west to east. The changeover will reach as far east as northeast MA, central MA, and northern CT by about 3 PM. It will reach RI and eastern MA (except Cape Cod/Islands) by between 7 PM and 11 PM Monday. The snow could continue into early Tuesday morning. Less snow is expected than what occurred on the front end Sunday, but there still could be several inches in some locations. This may be dependent on where localized bands of heavier snow set up. - Winds will gust to 35-45 mph along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA. - Storm surges of up to 2 feet are expected, but due to low astronomical tides, only splashover is expected for east coastal MA, including Cape Cod Bay and Nantucket (with northeast winds).

Amounts drop off rapidly as one heads southeast, with 3 to 5 inches from southern Hartford County eastward to Providence and Plymouth and less than an inch on Cape Cod and the Islands. *Confidence* : - Confidence remains highest in the warning areas of western and northern MA, where >6" of snow in a 12 hour period or 8" in a 24 hour period is likely. - Confidence remains low enough at this point, however, to have continued the Winter Storm Watch for many interior locations. This is due to not being completely sure of the extent of the warm air intrusion, which could greatly impact snowfall totals. A colder scenario by just a few degrees would mean more snow than currently forecast. Our lowest confidence is in southeast sections, particularly along the I-95 corridor. This could be a situation in which there is a sharp snowfall gradient within the city of Boston, with only a slushy inch or two at the immediate coast to warning criteria amounts in western Suffolk County. -- Glenn Field/Rodney Chai 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>

Good morning, We'd like to let you know our latest thinking on the significant winter storm expected Sunday through Tuesday morning. A Winter Storm Watch continues for portions of north central CT, northern MA and central MA, from midday Sunday through Tuesday morning. *NEW:* a *Winter Storm Warning* has been issued for north central Massachusetts and the east slopes of the Berkshires *Sunday through Monday Night Storm* *What: *Significant snowfall with impactful accumulations possible. A wintry mix will occur over portions of southern New England, especially eastern MA, RI and northern CT. - Snowfall accumulations could surpass a foot across much of interior southern New England. - Accumulations of 4 to 8 inches are possible along the I-95 corridor in northeast MA, including the Boston area, except 2 to 5 inches of snow is possible along the immediate shoreline. A wintry mix with sleet and rain is possible at times. - Accumulations of 5 to 10 inches are possible across north central CT. A wintry mix of snow, sleet and freezing rain is possible at times, with up to 0.2 inch of icing. - While a wintry mix is also expected over northeast CT, RI and into southeast MA, lesser accumulations are expected due to mixing with or a changeover to rain. Snowfall amounts mainly 1 to 4 inches are possible. *When:* Mid-day Sunday through Tuesday morning *Where:* Much of southern New England, where Winter Storm Warnings and Watches have been issued. We will keep you updated on our latest thinking with subsequent emails.

Good evening, Sending an update regarding the potentially significant winter storm for Sunday through Monday night. A Winter Storm Watch has been issued for north central CT, northern MA and central MA, from midday Sunday through Monday night. *Sunday through Monday Night Storm* *What: *Significant snowfall with impactful accumulations possible. A wintry mix may occur over portions of southern New England, especially eastern MA, RI and northern CT. - Snowfall accumulations could range from 6 to 12 inches across much of interior southern New England. - Accumulations of 4 to 8 inches are possible along the I-95 corridor in northeast MA, including the Boston area, except 2 to 5 inches of snow is possible along the immediate shoreline. A wintry mix with sleet and rain is possible at times. - Accumulations of 5 to 10 inches are possible across north central CT. A wintry mix of snow, sleet and freezing rain is possible at times, with up to 0.2 inch of icing. - While a wintry mix is also expected over northeast CT, RI and into southeast MA, lesser accumulations are expected due to mixing with or a changeover to rain. Snowfall amounts mainly 1 to 4 inches are possible. *When:* Mid-day Sunday through Monday night. *Where:* Much of southern New England, where a Winter Storm Watch has been posted. There remains a good deal of uncertainty as to the exact track of the storm and accumulation amounts. We will keep you updated on our latest thinking with subsequent emails.
