| Area Forecast Discussion National Weather Service Boston/Norton MA 550am EST Tuesday Nov 10 2026 .WHAT HAS CHANGED... No significant changes to the forecast. .KEY MESSAGES... - Dry & seasonable weather continues through mid-week with a good amount of sunshine. Temperatures range from the the 30s-lower 40s overnight to upper 50s in the afternoons. - Monitoring another storm Friday, although there remains high uncertainty in exact timing and storm track. KEY MESSAGE 1...Dry & seasonable weather continues through mid-week with a good amount sunshine. Temperatures range from the the 30s- lower 40s overnight to upper 50s in the afternoons. Dry westerly flow continues through the middle of the week under zonal flow at the mid levels, sandwiched between a surface low over eastern Canada and high pressure over the southeast U.S. Not much change in the airmass overhead with 925 mb temps in the 6-8C range Tue/Wed. Some lingering moisture in the mid/upper levels moves through early leading to increased cloudcover this morning, but drying out/clearing up by the afternoon with plenty of sun. This continues Wednesday though we'll start to see some moisture/increasing cloudcover filtering in later in the day Wednesday. Altogether, should see high temperatures each day topping out in the mid to upper 50s. KEY MESSAGE 2...Monitoring another storm Friday, although there remains high uncertainty in exact timing and storm track. The latest round of ensemble guidance continues to show large uncertainty in the development of a potential storm as we head into the late week/weekend, especially within the track of the low. While all guidance continues to indicate paths anywhere from Maryland to Nova Scotia, the ECMWF (European Centre for Medium-Range Weather Forecasts) and Canadian ensembles (and their AI ensembles) have trended towards the 40N/70W benchmark or slightly south while the GFS (Global Forecast System) ensemble shows tracks closer towards the southern New England coast. Despite the uncertainty in track, most guidance has indicated the low deepening into the mid 990mbs by early Friday morning as well as 850mb temperatures dropping to below freezing across southern New England by Friday evening, supporting chances for some snow to mix into the region Friday and Friday night across the higher elevation regions. Probabilities continue to indicate only a 30-50% chance for 1"+ of snow in the higher terrain, with the highest chances along the eastern slopes of the Berkshires, and less than 20% probability for 3" or more. As mentioned by previous forecasters, those probabilites assume a 10:1 snow to liquid ratio, and unless we get really heavy precipitation rates (highly unlikely), those 10:1 SLR accumulations would likely be lower with wetter snow characterization being more favored. Any winter weather impacts in the higher elevations are likely to be very limited to nil, and this is reflected by low probabilities of Minor winter storm impacts in the Probabilistic Winter Storm Severity Index. Heading into the second half the weekend, the low will push further into Atlantic Canada and high pressure begins to build over the Mid- Atlantic region, bringing a return to blustery and dry conditions to southern New England for the start of the next work week. Marine Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Through Wednesday night...High confidence. Westerly wind gusts of 20-25 knots will persist at times into early Wednesday with a second surge late of wind late Tuesday night behind a cold front. Therefore...have continued a Small Craft Advisory for many waters into Tuesday and even early Wednesday for our outer-waters before things finally diminish. Outlook /Wednesday Night through Saturday/... Wednesday Night: Winds less than 25 kt. Thursday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Seas locally approaching 5 ft. Chance of rain. Thursday Night: Strong winds with gusts up to 35 kt. Rough seas up to 11 ft. Rain, slight chance of thunderstorms. Friday: Strong winds with gusts up to 35 kt. Rough seas up to 12 ft. Rain. Friday Night: Strong winds with gusts up to 35 kt. Rough seas up to 12 ft. Rain likely. Saturday: Strong winds with local gusts up to 30 kt. Rough seas up to 11 ft. Rain likely.
