Point Forecast Updated Sat Nov 27, 2021 9:36am EST
Blustery and colder weather prevails today as high pressure gradually builds into the region. Low pressure is expected to develop off the mid Atlantic coast Sunday night and Monday, and could bring some rain or perhaps accumulating snow if it tracks close enough to our area. Mainly dry weather follows along with a warming trend later in the week.

000 FXUS61 KBOX 271407 AFDBOX Area Forecast Discussion National Weather Service Boston/Norton MA 907 AM EST Sat Nov 27 2021 .SYNOPSIS... Blustery and colder weather prevails today as high pressure gradually builds into the region. Low pressure is expected to develop off the mid Atlantic coast Sunday night and Monday, and could bring some rain or perhaps accumulating snow if it tracks close enough to our area. Mainly dry weather follows along with a warming trend later in the week. && .NEAR TERM /THROUGH TONIGHT/... 9 AM Update... Most of the adjustments in the latest update were made to the fire weather parameters. Increased the mixing heights and transport winds based on RAP/GFS/NAM forecast soundings as we were way too low. Should see some good mixing though it will be a bit offset by some suppression via downsloping. As for the rest of the forecast it is on track. Just have made some minor adjustments to bring things in line with observations. 7 am update... Satellite early this morning shows a mix of clouds and sun to start the weekend, with a mid level deck lingering especially from Worcester eastward where the last gasps of snow flurries are exiting the east coast. We'll see gradual improvement this morning, but the gusty northwest winds will stick around. Previous Discussion... Upper low over Gulf of Maine will move farther away from SNE today. Lingering bands of snow showers over NE MA will slowly push offshore early this morning while other bands near Berkshires gradually dissipate. So far we've received reports of 1-3" in the higher elevations of western/central MA and northern CT with little if any accumulation elsewhere due to warmer boundary layer temps. Not expecting any additional accumulation at this point so we plan to drop the Winter Weather Advisory for western Franklin County with this update. Otherwise expect clearing during morning as drier air works into region, despite continued cyclonic flow aloft. Forecast soundings show mixing up to 900 mb which is not overly deep, but leftover strong winds in that layer will support 25-35 mph gusts most of today before winds diminish late. Stayed close to NBM for high today, ranging from lower 30s NW to lower 40s near coast. && .SHORT TERM /SUNDAY/... Surface ridge remains over region tonight. Clear skies and light winds will allow temperatures to drop off quickly before we see some higher clouds arrive later at night. Sided closer to colder MOS for lows, with teens NW to mid 20s around Cape Cod/Islands. Warm advection gets underway Sunday ahead of next system. On larger scale, next 500 mb cutoff drops SE into eastern Great Lakes which induces secondary low development off mid Atlantic coast. Best synoptic scale lift appears to stay tied to primary low which tracks to our west, and pattern may stay progressive enough to allow secondary low to pass well to our SE (more on that below in Long Term section). For now expect increasing clouds Sunday but lower levels should stay dry enough to prevent much in way of precipitation. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... Highlights... * Chance for rain/measurable snowfall Sunday night into Monday * Below normal temperatures through mid-week become warmer by late-week. Sunday and Monday Latest model guidance continues to dig an upper-level trough over the northeastern US on Sunday. This will support the development of a low-pressure system off the mid-Atlantic coast on Sunday afternoon. There is agreement among deterministic/ensemble model guidance that this low will track far enough south to produce snow showers for a least some portions of southern New England. The south/southeastern areas should see mostly rain. Accumulations will be limited however, since global model guidance reveals weak synoptic forcing for ascent. The NAM (mesoscale) model on the other hand resolves an impressive coastal front across New England's east coast that if verified could support locally heavier snowfall (a few inches) across portions of interior MA into southern NH. We see a similar feature resolved within some of the EC ensemble members. The development of such a feature will rely heavily on how quickly the coastal low can deepen and intensify. With a slowly deepening system there won't be enough time for FGEN to ensue and provide forcing sufficient enough for any significant rain/snow accumulations. However, should the anomalously warm mid-Atlantic waters support a rapidly deepening low, we could see a strong coastal front develop along New England's east coast with the anomalously cold air mass in place over the interior. This scenario could support the potential for more substantial snowfall over portions of the interior. At this point however confidence is too low to forecast anything higher than a dusting to an inch or two of snow for areas north and west of Boston. The South Shore, Cape, Islands, and South Coast appear destined to see mostly rain from this system with an outside chance for a short period of non-accumulating snowfall Sunday night into Monday. We'll have more details on this system as more of the short-term mesoscale models become available. Tuesday through Friday Synoptic pattern characterized by a west-coast ridge/east-coast trough will continue to support cooler than normal temperatures over the Northeast through mid-week. May also see a chance for some showers during the Wednesday-Thursday time frame as an embedded short-wave traverses over the region. Large-scale flow pattern is forecast to change late week as a broad-upper level ridge builds over the east-coast. This is expected to result in temperatures climbing above normal late week and into next weekend. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/... Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. 12z update... VFR CIGS at all terminals this morning as skies clear from west to east between 13z- 16z.
