Good morning, Following is an updated weather briefing for a late-season accumulating snowfall expected tonight into Saturday morning across much of interior Southern New England and into eastern MA. *Changes with this update:* - *Winter Weather Advisory Issued for:* - *East Slopes of the Berkshires: *7 PM Tonight to Noon Saturday*.* - *Northern CT, Northern Providence County RI, and western & central MA:* 11 PM Tonight to Noon Saturday. - *Eastern/Northeastern MA (including Boston and the North Shore of MA):* 2 AM to Noon Saturday. *Details:* Light rain will develop across western MA late today, spreading eastward and mixing with/changing to snow tonight. The steadiest of the snow, potentially heavy with low visibility, is expected to fall during the overnight hours from the border of MA and CT/RI on northward towards the Mass Pike and Route 2. Snow wraps up later Saturday morning before turning back over to light rain showers. Mainly rain is expected for the entire event from southeast MA into central/southern RI. *What:* Accumulation of wet/heavy snow. Generally 2 to 4" for northern CT, northwest RI into eastern MA, 4-6" across Worcester County, and 4-6" (locally up to 8") for the Berkshires. *Where:* Most of Massachusetts, northern Connecticut, northwestern Rhode Island. *When:* Rain changes over to snow from west to east after 8 p.m. and continues until late Saturday morning. Period of greatest impact is overnight tonight due to heavy wet snow reducing visibility. Snowfall rates may be at or near 1" per hour in this overnight timeframe. *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 terrain in northern Worcester County and across the Berkshires. - Slushy/icy untreated surfaces and secondary roads across higher terrain. *Confidence: *We are most confident in snowfall totals along and north of the Mass Pike and at elevations above 1000 ft. There is some uncertainty with the snowfall totals in northern CT, northwest RI and eastern MA with temperatures being just above freezing and snow mixing with rain at times, and snowfall totals could end up lower than currently forecasted. Attached graphics include the current Winter Weather Advisory areas, the latest official snow forecast, and the chances of receiving 2 or more inches and 6 or more inches of snow. **Note:* Please consider the snow accumulation as *preliminary* and are subject to further adjustments.
