by BOX Operations - NOAA Service Account 23 Mar '20

23 Mar '20

Good afternoon, Here is the latest on the snow event impacting Connecticut, Rhode Island and Massachusetts. The key takeaway is snow amounts have been increased from previous forecast across northern CT into northwest RI and northeast MA. Please see the attached graphics which include: - NWS Winter Storm Warnings & Winter Weather Advisories - NWS Official Snowfall Forecast *NEW: * - Winter Weather Advisory for all of northern CT including Hartford, Windham and Tolland counties *What's Changed*: - Increased snow amounts across northern CT from Hartford to the RI border to 2-4 inches of snow before mixing with sleet and then changing over the rain 5 pm to 8 pm - Increased snow amounts across the northern portions of Middlesex and Essex counties where the Winter Weather Advisory has been posted. 2-4" expected here with highest totals likely along and near the NH border *What/Where/When: * - Western and central MA snow heavy at times continue into this evening then tapering off between 11 pm and 2 am. Snow will accumulate 4-8 inches across the high elevations with 2-4 inches in the valleys.* Locations that receive over 4 inches there is an increased risk of tree damage and isolated power outages given the heavy wet snow.* - Snow across RI and eastern MA (along and northwest of Boston to Providence) changes over to sleet and then rain between 5 pm and 8 pm with snow accumulations ranging from a coating up to 2 inches north and west of Boston to Providence. Snow accumulates mainly on the colder non paved surfaces with main roads remaining just wet - Little if any snow southeast of Boston to Providence line *Uncertainty:* - The exact timing of the changeover and resulting duration of snow is somewhat uncertain. If the changeover is delayed by an hour or two snow totals will be slightly higher. Conversely if the changeover occurs quicker than forecast snow totals will be lower.

[2020-03-23 AM] NWS Boston EM Briefing for Coastal Storm Monday into Tuesday Morning
by BOX Operations - NOAA Service Account 23 Mar '20

23 Mar '20

Good morning everyone, Here is the latest thinking about the coastal storm which will pass southeast of New England today into early Tuesday. It will bring snow to much of the area this afternoon before a change to rain Monday night. This is expected to be a minor snowfall event, with the exception of the higher elevations of western and central MA, where as much as 8 inches of snow is possible. *NEW:* - Northwest Middlesex County changed from a Winter Weather Advisory to a Winter Storm Warning *What/Where/When:* - Snow develops from west to east across much of southern New England Monday afternoon, except near the South Coast, Cape Cod, and the Islands where mainly rain is expected. - Snow is expected to be heavy at times late Monday afternoon into evening, especially in the Berkshires and northern Worcester Hills. Heavy snowfall rates could lead to snow-packed roads and difficult travel. - Snow mixes with and changes over to rain from south to north. The higher elevations of northern Worcester County and the Berkshires are expected to remain mostly snow. - The consistency of the snow will be heavy and wet. *Uncertainty:* - Snow amounts will be highly elevation-dependent, leading to potentially significant countywide differences in snow totals. - Portions of northwest Hartford County may see 3-5" with quickly diminishing amounts to the south and east. - If the coastal storm passes farther offshore, snowfall totals will be less, especially across the interior. - Conversely, if the storm tracks closer to southern New England, there would be less snow across most of the region, since the higher accumulations would shift to the northwest of MA. For more details, check out our winter page: https://www.weather.gov/box/winter Thank you Bryce Williams and Bill Babcock 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>
