DAYS 1-5 (JANUARY 23-27)…
Storm update! What to expect in southern New England…
WHEN: Today and tonight (except Sunday morning as well regarding tide impact).
SNOW START TIME: Already underway southwestern CT, remainder of South Coast of CT to Cape Cod mid to late morning, however by late morning a few snow showers unrelated to the storm are possible from near Boston to the North Shore and northwest Suburbs, otherwise the storm-related snow should reach northeastern CT, northern RI, and south central MA during the early afternoon and its furthest extend northward into MA to near the NH border during mid to late afternoon.
SNOW END TIME: From northwest to southeast generally between 8PM and 3AM, that is, firstly in the areas it reached the latest, and lastly around Cape Cod and the Islands closer to 3AM. This means areas near the South Coast snow the longest while areas northwest of Boston snow lesser time.
SNOW INTENSITY: Moderate snow as a general rule across most areas from Boston along the Mass Pike and southward, but a band of heavier snow will push into the South Coast of MA, RI, and CT. Light to very light snow as you head north and northwest toward the MA/NH border.
SNOW ACCUMULATION: Nothing or flakes in the air briefly in southern NH, dusting to 1 inch north central and northeastern MA, 1-3 inches from near Boston west southwestward along the Mass Pike belt and just to the north, 3-6 inches from just south of Boston down into much of southeastern MA to northern RI and northeastern CT, 6-10 inches southeastern CT and southern RI and the immediate South Coast of MA including the southern part of Cape Cod and the island of Martha’s Vineyard. Exceptions will be southwestern CT where over 10 inches will fall, Nantucket where an intense snow band may result in over 12 inches, and the eastern part of Cape Cod where slightly lighter precipitation and a possible mix may limit snow to 2-4 inches there.
WIND: Gusts of 30 MPH or greater are likely in coastal NH and northeastern MA, 40 MPH or greater from coastal areas near Boston to the South Shore, 50 MPH or greater Cape Cod across to coastal RI and down Martha’s Vineyard, and 60 MPH or greater on Nantucket.
POWER OUTAGES: The most likely area for any power problems will be the southern part of Cape Cod where the combination of strongest wind and wettest snow will be. Isolated outages possible elsewhere.
COASTAL FLOODING: Minor to moderate coastal flooding is most likely in the prone areas such as Scituate and Sandwich and similar locations from the South Shore of MA through Cape Cod and the from a couple hours before to a couple hours after high tide times both Saturday night and Sunday morning. Cannot rule out a pocket of major flooding since we have a full moon and astronomical high tides at this time. Major flooding would not be widespread in coastal areas.
After the storm! What to expect…
Improvement Sunday, fair and milder Monday, windy and not too chilly but a few rain showers Tuesday with an approaching cold front, then breezy and colder but fair weather Wednesday behind this front.
TODAY: Overcast. A band of light snow showers possible late morning to early afternoon from Boston area to the 128/95 belt around the city then may progress westward before dissipating, otherwise snow developing from south to north during the course of the day. Snow may mix with or even turn to rain at times on parts of Cape Cod and Nantucket. Highs 27-35, coldest over interior MA and southwestern to south central NH, mildest Cape Cod. Wind N to NE 5-15 MPH in areas northwest of Boston, NE to E 10-25 MPH with higher gusts elsewhere (see above for peak gusts).
TONIGHT: Snow retreats northwest to southeast, lastly on Cape Cod. See above for accumulations. Lows 23-30. Wind NE to N 15-30 MPH, higher gusts (see above).
SUNDAY: Lingering clouds Cape Cod for part of the morning otherwise mostly sunny. Highs in the 30s. Wind NW 10-20 MPH with higher gusts.
MONDAY: Partly cloudy. Lows 18-25. Highs 35-42.
TUESDAY: Mostly cloudy and windy. Brief light mix possible morning. Few rain showers late. Lows 28-35. Highs in the 40s.
WEDNESDAY: Partly cloudy and windy. Lows in the 20s. Highs in the 30s.
DAYS 6-10 (JANUARY 28-FEBRUARY 1)…
Fair weather is expected for most of if not all of this period but we may be in between systems in both the northern and southern jet streams January 29-30 so will have to keep an eye on these for most likely minor impact with any shift in storm tracks. Temperatures near to above normal.
DAYS 11-15 (FEBRUARY 2-6)…
Unsettled weather possible February 2-4 with an air mass battle possibly setting up in the area. Fair and a little colder by February 5-6 based on current timing.
