[2020.01.07 PM] NWS Boston EM Briefing: Scattered Snow Squalls This Afternoon, Developing Black Ice Tonight
by BOX Operations - NOAA Service Account 08 Jan '20

08 Jan '20

Good morning everyone, This e-mail is to raise awareness of scattered snow squalls for this afternoon into early tonight, with much colder air tonight contributing to the development of patchy black ice on untreated surfaces tonight. Details on each below: *Scattered Snow Squalls* *Where: *Possible anywhere in Southern New England, though greatest potential is into interior MA (near and west of I-495), northern RI and northern CT. *When:* Between noon and 6 PM today. *Impacts:* While not everyone will see snow squalls, areas that do will see short-lived heavy snow capable of brief whiteout conditions and gusty winds. A quick coating-inch of snow accumulation is possible in less than an hour's time in snow squalls. These conditions may make for difficult travel which could impact this afternoon's commute. *Uncertainty:* Coverage of snow squalls will be localized, with several areas staying dry. There is less certainty on snow squalls advancing into the coastal plain with temperatures hovering near or just above freezing. Following attachment is a Special Weather Statement sent this morning about our expectations for snow squalls this afternoon into tonight. *Black Ice/Freeze-Up* *Where: *Possible anywhere in Southern New England where snow and/or wet pavement exists. *When:* Developing tonight into the overnight. Threat should end after sunrise Thursday. *Impacts:* Wet or slushy pavement will turn slippery if untreated. Shaded locations, side streets, bridges and overpasses are most vulnerable. *Uncertainty*: Generally low with high confidence on sub-freezing temperatures. Gusty winds and drier air tonight may evaporate damp pavement in spots before freezing. Attached is a look at tonight's low temperatures based on our overnight/early morning forecast. While we are still fine-tuning these low temperatures, any change will likely be minimal. Please let us know if you have any questions or concerns! Thank You!

[2020.01.07 PM] NWS Boston EM Briefing: Accumulating Snow Overnight Across Southeast New England
by BOX Operations - NOAA Service Account 07 Jan '20

07 Jan '20

Good afternoon everyone, The only real change with this afternoon's update is a Wind Advisory which has been issued for Cape Cod, the Islands, and portions of western/central MA for Wednesday afternoon into Wednesday night (see attached). A Winter Weather Advisory remains in effect for south coastal Massachusetts, Cape Cod and the Islands for between 2 and 4 inches of snow overnight. See the attached expected Snow Accumulations/Winter Weather Headlines. *WHAT/WHERE:* - Winter Weather Advisory issued for 2 to 4 inches of snow overnight across south coastal MA as well as Cape Cod and the Islands. - Lower snowfall totals are anticipated further northwest, with a coating to 2 inches expected in the Boston to Providence corridor. *WHEN:* *- *The snow will begin after 10 or 11 pm tonight with the accumulating snow pretty much over by 5 am Wednesday morning. - The snow may begin as a period of rain across the outer-Cape/Nantucket, but will change over to snow. Snowfall rates may reach 1 inch per hour across far southeast New England for a short time overnight. - Threat for accumulating snow will have pretty much ended by the start of the Wednesday morning commute, but untreated roads may be snow covered and slippery. *UNCERTAINTY:* - High confidence that the heaviest snowfall will occur across far southeast New England, but exact snowfall amounts remain uncertain. - Current indications are for 2 to 4 inches of snow across south coastal MA, Cape Cod and the Islands. A coating to 2 inches of snow is expected further northwest into the Boston to Providence corridor. - If the storm tracks a bit further northwest, the low risk exists for 2 to 4 inches of snow further northwest across most of RI and most of SE MA with localized 5 inch amounts possible near the Cape Cod Canal - If the storm tracks a bit further to the southeast, any threat for accumulating snow would be confined to Cape Cod and the Islands and would be just an inch or two. Please let us know if you have any questions or concerns!
