by BOX Operations - NOAA Service Account 19 Dec '18

19 Dec '18

Good morning everyone, No significant changes to the forecast for late Thursday night into Friday. Heavy rain, strong winds and a risk for coastal flooding remain the primary concerns. At this time, only a Gale Watch for the waters has been issued beginning early Friday morning, however it is possible more headlines will be issued. *What / Where / When ...* - Heavy rainfall across all Southern New England - Rain starts late Thursday night, with heaviest rainfall expected early Friday into Friday afternoon, possibly lingering into Friday evening. - Rainfall amounts of 1.5 to 3 inches, with locally higher amounts possible. - Heavy rainfall will likely result in urban and poor drainage flooding, along with some river flooding as well. Moderate river flooding is possible if rainfall approaches 3 inches. - Strong southerly winds - The greatest risk for strong to damaging winds will be across SE New Eng, particularly RI and southeast MA and Cape/Islands during the daylight hours Friday, possibly into Friday evening. - Potential for wind gusts over 50 mph. - If strong winds are realized, tree damage and isolated to scattered power outages will be possible. - Minor coastal flooding along the south coast - Mainly during the early Friday evening high tide. - Storm surge around 2 ft possible with 12+ foot seas just offshore. - Minor flooding possible along the shores of Narragansett Bay and Buzzards Bay, as well as splashover and minor flooding along ocean exposed south coastal beaches. *Uncertainty ...* - Heavy rainfall: High confidence that heavy rainfall will occur, but there is uncertainty with respect to where the axis of heavy rainfall will set up and timing of the heaviest rainfall. - Strong winds: Uncertainty in the strength of the winds along the south coast and extent of any wind damage, and also the timing of the strongest winds. - Coastal flooding: There is uncertainty if there will be enough storm surge during the Friday evening high tide to produce minor flooding. We will continue to update over the next 48 hours.

[2018.12.16 PM] NWS Briefing #4
by BOX Operations - NOAA Service Account 16 Dec '18

16 Dec '18

Good afternoon everyone, Winter Weather Headlines remain posted for western-central Massachusetts this evening and overnight. Here are the details ... *What / Where / When ...* - *What* - rain changing to sleet/ice pellets then all snow - *Where* - western & central Massachusetts (east slopes of the Berkshires into the Worcester Hills) - *When* - this evening and overnight - *Headlines* - Winter Weather Advisories remain posted for western-central MA - *Impacts* - slippery snow covered roads especially at elevations above 1000 ft. Heaviest precipitation occurs from approximately 6 pm this evening to 2 am then diminishing thereafter with just light snow expected during the Monday morning rush hour. No impacts other than wet roads expected from Boston to Providence to Hartford. - *Uncertainty* - there is some uncertainty how quickly rain will change over to sleet then snow this evening along with how quickly will snow begin to accumulate on paved surfaces. Given the lack of cold air currently across the region combined with a slow transition expected from rain to sleet to snow our snowfall accumulations are only a coating to 2 inches with highest amounts above 1000 ft. However if the changeover to snow occurs more rapidly then more snow is possible (worst case scenario - 90 percentile forecast) with 2 to 5 inches a low probability from the east slopes of the Berkshires into the Worcester Hills. Therefore stay tuned to later forecasts and discussions to see how this weather event evolves.

by BOX Operations - NOAA Service Account 16 Dec '18

16 Dec '18

Good morning, We continue to forecast a wintry mix of snow, sleet and freezing rain across northern and western portions of Massachusetts and Connecticut for today into this evening, transitioning to mainly snow this evening, concluding into Monday morning. Winter Weather Advisories continue accordingly for the threat of ice accretion associated with freezing rain. *What / Where / When ...* - Wintry mix of sleet and / or freezing rain across northern and western portions of MA and CT - Low risk this morning across CT. - Main rain during the day across southern New England, transitioning to a wintry mix late this afternoon and evening across the higher terrain - Minor sleet/snow accumulations of a coating up to 2 inches are forecast, as well as ice accretion of a trace up to around 0.10" in spots - Greatest travel impacts will be potentially slick roadways and perhaps lower visibility across the high terrain, especially at elevations above 1000 feet - Sleet, freezing rain, even some locations observing rain change to snow this evening into Monday morning - Northern and western portions of MA & CT, possibly as far SE as the N&W I-495 beltway & I-84 corridor including NW RI - Mainly for higher elevations with temperatures at or below freezing, will see accumulations of a coating up to around an inch with the greatest travel impact - At lower elevations, not expecting much if any snow accumulations as roads will remain wet - With any snow, anticipate reductions in visibility *Uncertainty ... * Given a mixed precipitation event, there remains uncertainty with respect to precip-types at specific times over particular areas, as well as associated outcomes and impacts. As of now the greatest impact appears across the higher elevations of northern and western portions of MA and CT. However if the storms intensifies more rapidly than expected wintry precipitation may occur farther south and east. There will likely be adjustments to later forecasts so stay tuned to further emails. Should you have any questions, comments and/or concerns, please don't hesitate to reach out to us at any time.
