Calm Tuesday; Major Snow Wednesday

Good morning!

With partly cloudy skies, expect a high around 40 today, with a north wind around 5-10 mph. Tonight will be mostly cloudy and 28, with a light northeast wind.

And now, for more details on our major snowstorm.

Timing:
Snow begins mid-morning Wednesday, with a steady but probably not too heavy rate of snowfall by midday. The heavy snow starts in the mid to late afternoon, with the height of the storm being from Wednesday evening’s commute through Thursday morning’s commute. Snow will be tapering off by mid-morning Thursday and be completely done by around noontime on Thursday.
Uncertainty / Precip Type:
All snow is expected. However, the location of the rain/snow line will still play a role in exactly how much snow we get. Some fluctuations in the snow forecast in either direction are possible as such, but I do not anticipate needing to dramatically change the forecast. If we end up closer to the rain/snow line than expected, we would be getting a much wetter snowfall; we are already getting a fairly wet snowfall. Thus power outages are possible (see below).
Other Hazards:
Wind gusts up to 35 mph will be possible. This will result in reduced visibility and the potential for blowing and drifting snow. This, combined with the weight of this heavy wet snow and weakened tree limbs from our last storm, will result in a risk of power outages. Make sure your electronics are charged!
Snowfall Totals:
I have Dracut in the 14-18″+ range. We will probably end up in the lower half of that range.

Expanding on the precipitation type discussion, those in the 10-14″ and 14-18″ ranges should stay entirely snow, except perhaps a brief period of rain around midday Thursday in southern and eastern sections of the 10-14″ range. This should not affect overall totals. 7-10″ should be mostly snow with a period of mixing likely. Extensive mixing and high uncertainty will exist in the 2-4″ and 4-7″ range. 0-2″ should be mostly rain.
0-2″: Southeast MA, Southern RI, Southeast CT
2-4″: southern suburbs of Boston, central Rhode Island, parts of east-central and south-central CT, as well as Cape Ann in northeast MA
4-7″: Boston, immediate northern suburbs of Boston and North Shore coastal towns (except Cape Ann), southwest suburbs of Boston, northeast Rhode Island, parts of south central CT
7-10″: North Shore of MA from Ipswich to Boston, except away from the immediate coastline (only reaching the coast at Ipswich); roughly following I-95 to just west of Boston, then a small section of Boston’s western suburbs; west- and north-central Rhode Island; most of southern CT
10-14″+: Most of interior northeast MA; coastal areas from Ipswich on north; eastern NH; southern ME; interior MA south of the Mass Pike; northern CT
14-18″+: Interior northern MA, west of the section of I-495 between Methuen and Marlboro; most of NH; southern VT. Most spots see around 15″ with higher totals nearing or exceeding 18″ favored in the higher elevations.
Beyond The Storm
Thursday will get to around 40, Friday 42, and Saturday 45 with decreasing clouds each day.

Have a great day! I’ll have more later.
