[2020.01.18 PM] NWS Boston EM Briefing: Snow will continue to move across the region through
by BOX Operations - NOAA Service Account 18 Jan '20

18 Jan '20

Good afternoon. Here is this afternoon's update for the storm that will continue to impact the region into early Sunday morning. *No major changes from the late morning update.* *Overview...* Light snow has been steadily moving east across central and western areas. At 3 PM, the leading edge of the light snow had reached as far north as Worcester and Orange, though it remains spotty across western Massachusetts into northern Connecticut. *Timing...* - The steady snow has moved into *Hartford* at 315 PM, with visibility lowering to 2 miles and will reach across the remainder of northern Connecticut by 4 PM. - Arrival time for the remainder of the region: - Central Massachusetts and Rhode Island by around 5 PM - Eastern Massachusetts by around 6 PM *Duration...* - This system continues to move quickly, so the snow should only last for about 3 to 6 hours. However, there will be periods of briefly heavy snow, which may fall at up to an inch per hour, which will quickly cover roadways and lower visibility. - *Approximate timeline of the steadiest snowfall*: - --* Boston:* 7 pm to midnight -- *Worcester to Springfield *6 pm to 11 pm - -- *Providence* 7 pm to 10 pm --* Hartford *6 pm to 10 pm *Impacts:* - In those areas where locally heavy snow falls, roadways and sidewalks will quickly become snow covered, especially where they are untreated. - Travel will be difficult through early tonight with poor visibility, but improvement is expected by around or after midnight. *Snow Totals:* - Most of the region will receive around 3 to 7 inches of snow. Higher amounts are expected across north central and western Massachusetts, with lower amounts near the south coast and across Cape Cod and the islands. - Temperatures will slowly rise as the precipitation starts to taper off by around 11 PM or midnight, so expect the snow to change over to light rain or drizzle across RI and SE Massachusetts before ending. - Snow may end as a period of light freezing drizzle across portions of interior Massachusetts and northern Connecticut toward midnight. Little additional impact expected from that with that falling on top of the earlier snow. *Forecast Confidence ... * - High confidence in several inches of snow through early tonight. - High confidence that snow will stick, especially on untreated roadways with cold ground temperatures. - Localized snow banding may result in some locations getting 1 to 2 inches more or less than what is currently expected, but overall this is a rather high confident forecast. This will be the last email on this event unless conditions change.

18 Jan '20

Good morning everyone, Here is a late morning update for the storm expected to impact southern New England later today into late tonight. *What has changed ...* - Looks like we will see the lower end of the snowfall thresholds on the expected snowfall map (see attached). - Looks like it is going to take a bit longer for snowfall to begin. Things should begin approximately 1-2 hours later than previously expected. - Snow overspreading western MA and northern CT around 5 to 6 PM and reaching eastern MA by 6 or 7 PM. Everything else remains on track, but for completion sake here is additional information from the previous email sent out below. *Timing ... * - Bulk of the accumulating snow begins to taper off between 10 pm and 1 am from west to east. *Duration ... * - This is a fast moving system so the snow will be limited to roughly a 3-6 hour window, but will fall moderate to perhaps briefly heavy for a short time. - Here is an approximate timeline of the steadiest snow/precip - * Boston:* 7 pm to midnight,* Worcester to Springfield *6 pm to 11 pm, *Providence* 7 pm to 10 pm,* Hartford* 6 pm to 10 pm. *Impacts ...* - Not a block buster snow event but it will snow moderate to briefly heavy for a 3-6 hour window (times above) with snowfall rates up to an inch per hour possible during this time. - Cold roads will become snow-covered and slippery immediately after the snow commences. Travel will be difficult this evening with poor visibility too, but improvement expected after midnight. *Snow Totals ... * - Most of MA, RI & CT will receive a quick 3 to 7 inches of snow. Higher amounts towards western and northern MA with the lower amounts near the south coast and Cape. - Snow will end as light rain or drizzle towards midnight across RI/SE MA with temps rising above freezing. - Snow may ends as a period of light freezing drizzle across portions of interior MA and CT towards midnight. Little additional impact expected from that with that falling on top of the earlier snow. *Forecast Confidence ... * - High confidence in several inches of snow falling late today and this evening. - High confidence that snow sticks to roadways immediately with cold ground temperatures. - Localized snow banding may result in some locations getting 1 to 2 inches more or less than what is currently expected, but overall this is a rather high confident forecast. An additional email will be sent later this afternoon.

Good morning everyone, Very little change made to the forecast early this morning, but we did extend the Winter Weather Advisory further south onto the south coasts of RI & MA including Cape Cod. Please see the outline below for more details.

[2020.01.17 PM] NWS Boston EM Briefing: Winter Storm Warnings & Advisories Posted
by BOX Operations - NOAA Service Account 17 Jan '20

17 Jan '20

Good afternoon everyone, Here is the latest forecast update regarding the snow event Saturday afternoon & evening ... *What has changed ...* - *Winter Storm Warnings* for 4-7" of snow have been posted for western & northern portions of MA and Litchfield county of northwest CT - *Winter Weather Advisories* for 2-4" of snow have been posted for the remainder of MA/RI and CT except no headlines for south coastal MA and RI including Cape Cod and the Islands where 1-3" of snow is expected before changing over to rain before ending. *Timing ... * - Snow overspreads the area Saturday between 3 pm to 6 pm from west to east - Precipitation begins to taper off between 10 pm and 1 am from west to east *Duration ... * - This is a fast moving system so precipitation will be limited to roughly a 3-6 hour window - Here is an approximate timeline of the steadiest snow/precip - * Boston:* 6pm to midnight,* Worcester to Springfield *5 pm to 11 pm, *Providence *6 pm to 10 pm,* Hartford* 4 pm to 10 pm *Impacts ...* - Not a block buster snow event but it will snow moderately for a 3-6 hour window (times above) with snowfall rates up to an inch per hour possible during this time. - This will result in roads becoming snow covered late Saturday afternoon and evening along with poor visibility. Travel will become difficult during this time. *Snow Totals ... * - Most of MA, RI & CT will receive 2-4 inches of snow before snow briefly changes over to rain and/or a wintry mix before ending around midnight or shortly thereafter - Western & northern Massachusetts along with northwest CT will likely receive the highest totals of 4 to 8 inches while the south coast of MA and RI likely only receive 1-3 inches before changing to rain before ending. This includes Cape Cod and the Islands. *Forecast Confidence ... * - Still some uncertainty on the exact timing of the changeover from snow to rain or a brief wintry mix. Therefore three snowfall maps are included to express this uncertainty, StormTotalSnow (most likely snowfall), SnowAmt10PrcntilISC (low end amount) and SnowAmt90PrcntilISC (high end amount). Given the very cold airmass over the region late today and continuing overnight with morning lows Saturday in the single digits and teens, this may delay the changeover and result in an hour or two of additional snowfall. Therefore our most likely snowfall map is very close to the high end snow map. Given the event is still about 24 hours away the exact timing may change by an hour or two with later forecasts along with snow amounts increasing or decreasing by an inch or two. Thus stay tuned to later forecasts and discussions. The next email briefing will be issued around 4 am to 5 am Saturday.

[2020.01.08 AM] (CORRECTED Date/Time) 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, Following e-mail is a correction to one previously sent with a corrected date/time stamp. Information contained is unchanged from the previously sent e-mail and remains valid. Apologies for the error! 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!
