Synopsis for massachusetts and rhode island coastal waters - High pres building well to our sw today will allow winds and seas to diminish to small craft advisory levels. A low pres passes by to our N Sat night into Sun leading to possible gale warning conditions. This high pres moves off the se coast early next week, allowing for mainly W to sw winds over the waters later this weekend. Another low pres should approach the waters towards the middle of next week.

Area Forecast Discussion National Weather Service Boston/Norton MA 1232 AM EST Sun Dec 8 2024
SYNOPSIS
An Alberta Clipper system passing across northern New England tonight will bring minor accumulations of snow to areas north of the Mass Pike, with coatings for the majority of our area.
Milder temperatures expected for much of next week with a period of rain sometime Monday, and again by Wednesday. We will need to watch for a temporary period of shallow cold air later Monday into Tuesday with Quebec high pressure system.
NEAR TERM /THROUGH TODAY/
* Light snow overnight with accumulations up to an inch north of I-90
Current forecast timing still appeared to be on track, and was supported by the last few runs of the HRRR and RAP. Still expecting a light snowfall across northern New England, especially north of I-90 and northwest of I-495. No major changes to snowfall accumulations this evening. Did bring temperatures and sky cover back in line with latest observations.
Previous Discussion...
A progressive Clipper system will result in several hours of light snowfall for most of southern New England overnight.
Southwest flow will support low-level WAA over southern New England which will be the driving for precipitation this evening. Antecedent conditions are favorable for snow tonight as surface temps across the region are currently in the mid to upper 30s. Once the sun sets it won't take long for temperatures to dip back to freezing allowing for the warm frontal precipitation to fall as snow, at least for areas away from the south coast, Cape, and Islands. Recent 12Z suite of model guidance has backed off a smidge with respect to precipitation amounts, but we're still expecting around a tenth of an inch of liquid precipitation between roughly midnight and 6AM. This will translate to a dusting to an inch of snow accumulation with the highest amounts north of I-90 and northern Berkshires.
Expect snow to begin between 11PM and 1AM west of I-495 before reaching areas east of I-495 between 1AM and 3AM. As mentioned previously, this will be a progressive system, so expect snow to be wrapped around sunrise (5-7am).
SHORT TERM /TONIGHT THROUGH 6 PM MONDAY/
Key Message for Sunday and Sunday night
* Gusty southwest winds Sunday morning into early Sunday afternoon
* Milder temperatures Sunday afternoon in the mid to upper 40s
Any lingering snow showers should be tapering off around sunrise as skies begin to clear from west to east. Thereafter, southwest winds and low-level WAA will continue to transport warmer air into southern New England. As this occurs, a robust low-level jet will develop over the region and may support a period of gusty southwest winds for the first half of the day. Areas at elevation in the Worcester Hills may see 20 to 30 mph gusts while The Cape and Islands could see gusts in the 30 to 40 mph range. Elsewhere, gusts should be more modest, topping out around 20 to 25 mph. As the gradient slackens into the early afternoon, wind gusts will gradually diminish into the evening hours. The milder air mass will support above normal high temperatures in the mid to upper 40s.
Tomorrow Night
Winds become light and variable after midnight. With clear skies overhead, this should support efficient radiational cooling. The air mass will be relatively mild for December with 925 hPa temps right around freezing, thus low-temps will be mild compared to last week, but still close to normal ranging from the lower to upper 20s.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
Key Messages:
* Unsettled start to the work week with mixed precipitation possible Monday evening into Tuesday morning
* Deepening trough and its associated surface low bring widespread soaking rain Wednesday into Thursday
* Drying out going into next weekend
Have moderate confidence in the overall synoptic pattern into the middle of next week. Confidence drops off in the details late next week into next weekend. Mid level pattern expected to evolve from a nearly zonal flow to one with an amplified trough over the central USA. This places southern New England on the warmer side, resulting in a trend to above normal temperatures by Tuesday, and especially into Wednesday. This is short-lived, with below normal temperature more likely late next week into next weekend.
At the surface, yet another low pressure should move from the Great Lakes into southern Canada. Most of the guidance suggests the development of a secondary low pressure towards southeast MA Monday night into Tuesday. Otherwise, just a pair of fronts to trigger some rainfall. There is a low chance for some snow or freezing rain with precipitation onset Monday at the higher elevations, but that would not last long.
Another low pressure should pass through our region from the southwest some time from late Tuesday night into Wednesday night. Expecting a period of widespread rainfall, with a chance for a few thunderstorms ahead of a cold front. These thunderstorms would be mainly towards southern RI and southeast MA.
High pressure from the central US should begin to build towards our region Friday, then pass offshore Saturday. Most likely looking at a brief cool-down Thursday night into Friday, before starting another warming trend for Saturday.
