[2023.02.24 PM] NWS Boston EM Briefing: Potential Winter Storm for Monday Night through Tuesday Night
by BOX Operations - NOAA Service Account 24 Feb '23

24 Feb '23

Good afternoon, We are monitoring a potential winter storm that has the potential to bring accumulating snow and/or a wintry mix to Connecticut, Rhode Island and Massachusetts Monday night into Tuesday night. The storm's track and strength, and the potential for it to bring a changeover from snow to wintry mix in parts of Southern New England is still uncertain. That uncertainty is too large to provide specifics on snow accumulations. However we wanted to provide you with snowfall probabilities of both 4 inches and 8 inches. Those images are attached, along with a one-page briefing regarding this evolving winter storm forecast. Unless there are significant changes, expect the next briefing to be issued *Saturday late afternoon*. Thank You!

[2023.02.24 am] NWS Boston EM Briefing: Strong Winds Friday
by BOX Operations - NOAA Service Account 24 Feb '23

24 Feb '23

Good morning, A strong cold front will be moving through MA, CT & RI early this morning, and accompanied by increasing northwest winds of 20 to 30 mph, with gusts up to 45 mph. Tree limbs still covered in ice from recent freezing rain (up to a 1/3 of an inch of ice accretion in northern CT Thu), may be more susceptible to being downed by the strong winds. Therefore, a wind advisory has been issued for western & central MA, northern Connecticut and all of RI. Winds are not expected to be quite as strong across eastern MA. Strong northwest winds begin to diminish after sunset Friday, with light winds expected Saturday.

[2023.02.23 PM] NWS Boston EM Briefing: Icy Mix Tonight, Strong Winds Friday
by BOX Operations - NOAA Service Account 23 Feb '23

23 Feb '23

Good afternoon, Following is an update to the ongoing wintry mix event currently affecting CT, RI and MA. There has been little to no significant change to that which was briefed this morning. Winter Weather Advisories for the risk of icing, either through light accretions of freezing drizzle/freezing rain or from freeze-up of standing waters or slush, continue in effect tonight. In addition, Wind Advisories continue for the Berkshires due to the risk of strong wind gusts up to 50 mph acting on ice-coated trees and powerlines. Friday evening will also be quite cold, with sub-zero wind chills across areas north of the Massachusetts Turnpike, and between 5 to 10 below zero across the Berkshires. Attached graphics include the additional amounts of icing anticipated this evening, as well as the peak wind gusts for Friday. Expect this to be *the final briefing* for this weather scenario, unless there are significant changes to the forecast. Thank You!

[2023.02.23 AM] NWS Boston EM Briefing: Wintry Mix into Thu night
by BOX Operations - NOAA Service Account 23 Feb '23

23 Feb '23

Good morning, Changes with this forecast update include - - A wind advisory for western MA, including the Berkshires - NW winds Friday with gusts up to 50 mph, combined with possible ice covered trees, will increase the risk for potential power outages (see attached Wind Advisory map) Otherwise, winter weather advisories remain posted through Thursday night for all of MA, RI & CT, except southern portions of RI and MA, where temperatures will remain above freezing. A wintry mix of precipitation across northern MA Thursday morning, with all rain in CT, RI and southeast MA, will taper off to drizzle later this morning and eventually areas of freezing drizzle this afternoon, as temperatures drop below freezing. This will also result in a flash freeze this afternoon and evening, as any standing water or slush freezes, yielding icy travel, especially on untreated roadways and surfaces. Another round of a wintry mix is expected later this evening and overnight, finally giving way to dry weather Friday. Attached is a loop showing hourly temperatures dropping this afternoon and evening. Also, a graphic is included showing the potential for additional icing through tonight.

[2023.02.22 AM] NWS Boston EM Briefing: Wintry Mix Wed evening into Thu night
by BOX Operations - NOAA Service Account 22 Feb '23

22 Feb '23

Good morning, A wintry mix of precipitation will overspread CT, RI and MA between 5 pm and 9 pm Wednesday, and continue into Thursday morning. Precipitation will mainly rain across much of RI and southeast MA. Steady precipitation Thursday morning transitions to spotty light freezing drizzle Thursday afternoon, especially across northern MA. Colder air may spread south and east Thursday afternoon and evening into eastern MA, including the Greater Boston area. This may result in a flash freeze, with any standing water/slush freezing, resulting in slippery travel. Another round of wintry precipitation may impact the region Thursday night, especially northern MA. Attached is an expected storm total ice & snowfall graphics, and a Winter Weather Advisory map. In addition, a simulated radar loop is included, not expected to be exact, but to provide an overview of precipitation type, timing and evolution of precipitation for the entire event through Thursday night.

[2023.02.21 PM] NWS Boston EM Briefing: Multiple Mixed Wintry Precip Events This Week
by BOX Operations - NOAA Service Account 21 Feb '23

21 Feb '23

Good afternoon, The first of two minor events passed us by earlier today, with the second arriving this evening. Expecting up to 2" of snow across the higher terrain of MA, with mainly rainfall elsewhere. Attached is a model simulated radar loop, not expected to be exact, but to give you a feel for the overall precipitation type, timing and evolution of precipitation this evening. Also, attached is a map with potential snowfall for this evening. A more significant winter weather event is possible Wednesday night through Thursday night, when a mix of snow, sleet and freezing rain is expected to impact the region, with the greatest impact likely across northern Massachusetts. Slippery travel may impact the Thursday morning commute. The attached map (potential weather impacts) indicates the area with the greatest impact likely across northern MA.

[2023.02.21 AM] NWS Boston EM Briefing: Multiple Mixed Wintry Precip Events This Week
by BOX Operations - NOAA Service Account 21 Feb '23

21 Feb '23

Good morning, Two minor/nuisance precipitation events are expected this morning and again this evening/overnight, with a mix of snow and rain. Given temperatures will be above freezing, roads will remain mainly wet, with little to no impact. However, across the high terrain of Massachusetts, including the Worcester Hills, temperatures around freezing may yield snow accumulations of 1-3 inches, mainly on non paved surfaces, except across the highest elevations, especially on secondary roads and untreated surfaces. 1-3 inches is the total accumulation for both events, this morning and again this evening and overnight. Attached is a model simulated radar loop, not expected to be exact, but to give you a feel for the overall precipitation type, timing and evolution of precipitation this morning through tonight. Also, attached is a map with potential snowfall for this morning through tonight. A more significant winter weather event is possible Wednesday night through Thursday night, when a mix of snow, sleet and freezing rain is expected to impact the region, with the greatest impact likely across northern Massachusetts. Slipper travel may impact the Thursday morning commute. The attached map (potential weather impacts) indicates the area with the greatest impact likely across northern MA.

[2023.02.20 PM] NWS Boston EM Briefing: Multiple Wintry Weather Events This Week
by BOX Operations - NOAA Service Account 20 Feb '23

20 Feb '23

Good afternoon, We are looking at a fairly active period of weather for the workweek, with multiple periods of wintry weather to contend with. We have two generally minor/nuisance events, overnight tonight into Tuesday morning and another for Tuesday late afternoon into Tuesday night. However a more significant winter storm then looks to affect Southern New England Wednesday night through Thursday night involving accumulating snow, sleet and freezing rain. It is this latter storm system which has the greatest concern for widespread wintry weather impacts this week. Each storm will be discussed below: *Storm #1: Overnight into Early Tuesday AM [CT, RI and Southeast MA] * A weak and fast-moving low pressure moving across our southern coastal waters overnight tonight into early Tuesday morning to spread steady light snow (or brief rain at the onset then changing to steady light snow) across Connecticut, Rhode Island and into southeast Massachusetts. While snow accumulations with this fast-moving storm are limited to no more than 2 inches, snow will be falling during the morning commute and could pose difficult travel for commuters during the Tuesday morning commute, including reduced visibility and possible slushy, slippery roads. Image below shows our latest snow forecast for overnight tonight into Tuesday morning: [image: snowtues.png] *Confidence*: High confidence on snow occurring, but lower on the northern extent of minor accumulations and the total accumulations. Much of what falls will be on grassy surfaces, with slushy accumulation on paved surfaces. *Storm #2: Tuesday Late Afternoon to Tuesday Night [Mainly North and West of I-495]* The next fairly weak and fast-moving storm then moves in later Tuesday afternoon into Tuesday night. While mainly plain rain is anticipated for Connecticut, Rhode Island and eastern and southeast Massachusetts, temperatures should be cold enough for minor accumulating snow in the Merrimack Valley, central Massachusetts and into the Berkshires in western Massachusetts. Coatings to up to 2 inches of new snow appear to be common, with local/isolated amounts up to 4 inches in the Berkshires. We expect accumulating snow to end shortly after midnight. Following image is our snowfall expectations for Tuesday late afternoon to Tuesday night: [image: snowtueswed.png] *Confidence: *High on the event occurring, but moderate on the total accumulations. Greatest accumulation potential mainly in the higher terrain. Snow will likely be wet and slushy. *Storm #3: Wednesday Night through Thursday Night [All of Southern New England, but especially along and north of Interstate 95]. * A stationary front lying in the vicinity of Southern New England to lift northward Wednesday night through Thursday night, bringing a mix of wintry precipitation types to the area. Forecast remains little changed from that which was briefed early this morning. Accumulations of snow, sleet and/or freezing rain are all possible, with the potential for adverse impacts. It still is too early to provide specific details on precipitation type changeovers and forecast accumulations as yet. Attached is our one-page briefing which was previously sent and remains valid at this time. *Confidence*: Moderate to high on the event occurring, but low on snow/sleet and ice amounts. Snow/sleet and ice amounts will be sensitive to small changes in temperatures and the storm's track, and thus could vary, perhaps significantly. Expect an update to this briefing *no later than Tuesday morning*. Thank You!
