Good morning everyone, The wind advisory has been expanded to include all of Massachusetts, Rhode Island and northern Connecticut. We are forecasting northwest winds of 25 to 35 mph, with gusts to 45-55 mph. Given that many trees are in the process of greening up, this would increase the likelihood of some scattered tree damage and power outage potential. See the attached graphics for more info and let us know if you have any questions.

[2020-04-18 AM] NWS Boston EM Briefing: Ongoing Accumulating Snow through Mid-Saturday Morning
by BOX Operations - NOAA Service Account 18 Apr '20

18 Apr '20

Good morning, Following is an update on the ongoing wet snow event impacting Southern New England. *Changes to Winter Weather Headlines: * The Winter Storm Warning in the Berkshires have been downgraded to a Winter Weather Advisory. *Details:* We are nearing the tail end of this snow event across Southern New England, and snow has started to lighten across the Berkshires. Recent snow reports as of early morning have been under 2.5" in most locations, and much of that accumulation has been reported to be on grass. Accumulating snow is expected to continue for areas from Hartford CT to Providence RI to Plymouth MA northward through mid-morning before transitioning over to rain. An additional 1 to 3 inches of wet snow is expected before the change to all rain. Unless conditions warrant otherwise, this will be the last update regarding this late-season wet snow event. Thank You!

[2020-04-17 PM] Correction - NWS Boston EM Briefing: Snow tonight into Saturday morning
by BOX Operations - NOAA Service Account 17 Apr '20

17 Apr '20

*... The probability graphics for 4+" and 6+" have been corrected...* Good afternoon, Here is the latest on the snow storm that is expected tonight into Saturday morning across much of interior Southern New England and into eastern MA. *Changes with this update:* - *Winter Storm Warning now in effect for **western Franklin, western Hampshire, western Franklin, and all of Worcester County (7 PM tonight to Noon Sat.) * - *Winter Weather Advisory expanded southeastward to include Bristol and Plymouth Counties in southeast MA, except along the immediate south coast and all of Providence County in RI (**7 PM tonight to Noon Sat.)* *Details:* *What and Where:* We are expecting light rain to develop across western MA toward evening, then spreading eastward and mixing with and changing to snow. The snow may become heavy at times for a few hours, with 1 to 2 inch per hour rates and low visibility spreading eastward between 11 PM and 5 AM. Although road surfaces may be relatively warm to start, the heavy rates will cause rapid accumulation on roadways. The snow will mainly fall north of a line from Hartford to Providence to Plymouth. South of that area, mainly rain is expected. The snow will taper to flurries and light rain showers by mid morning Saturday. Expected snow accumulations: - In Massachusetts... 4"-8" in the east slopes of the Berkshires and in Worcester County; 3"-4" west and south of the Boston metro area; 1"-3" in the immediate Springfield metro area and from Boston northward to Cape Ann; 1" or less south coast and Cape Cod. - In Connecticut... 3"-6" in the higher terrain of northwest Hartford County and northeast Tolland and Windham Counties near the MA border; 0-2" in southern Hartford, southern Tolland, and southern Windham Counties, including the immediate Hartford metro area. - In Rhode Island... 2"-5" in northernmost Providence County; 1-3" in central RI, and 0 to 1" in the southern third of RI. *When:* Rain changes over to snow from west to east after 8 PM. Snow becomes heavy at times overnight and becomes light and mixes back with rain Saturday morning. Period of greatest impact is overnight tonight due to heavy wet snow reducing visibility and clinging to power lines. *Impacts:* - Heavy/wet snow may lead to power outages and tree/limb damage [where more than 4 inches of snowfall occurs]. Greatest potential for this includes the east slopes of the Berkshires and northern Worcester County. - Slushy/icy untreated surfaces and secondary roads. *Confidence: *This is now a moderately high confidence forecast. The biggest question is how far southeastward into southeast MA the appreciable snowfall will be. The attached graphics show: Watches/Warnings; Expected Snowfall Totals; Probabilities of Greater that 4" and 6" of snow.
