DAYS 1-5 (JANUARY 28 – FEBRUARY 1)<\/p>\n\n\n\n
A storm will impact our region today into Monday with a variety of precipitation, the type dependent on the precise temperature profile of the atmosphere at any given location. The basic idea remains the same as discussed yesterday. A shield of precipitation overspreading the region from south to north is ongoing and will be completed by midday. Higher elevation areas further west and north see snow longer than anybody else from the initial batch, and where it starts as a mix or rain it can flip to snow when it comes down heavier, due to the dynamic cooling process. Accumulations can be variable, not so regionally uniform, during the initial phase of this event. Low pressure does track in a place that typically would bring fairly widespread snowfall regionwide, but as mentioned yesterday, the lack of cold in place ahead of the system makes that more difficult, and not only does the storm manufacture cold during its occurrence for snow to occur, but it’s during the final hours of the storm, after a mid-storm lull due to mid level drying, that cold air moves in from the north and northwest, flipping the precipitation to snow for everyone from northwest to southeast. For areas that saw mix\/rain for many hours during the passage of the system, this would be when most of the snow accumulation occurs. The storm breakdown that I posted yesterday, with a couple tweaks, is repeated next…<\/p>\n\n\n\n
Precipitation arrival time \/ type: Ongoing as rain (some mix) South Coast, spreading north and northeast through all of the region by midday as rain with pockets of mix\/snow, except mostly snow in areas north of Route 2 and west of I-95, with bursts of snow further east and south with any moderate (heavy enough) precipitation. This phase of the storm’s precipitation continues through dusk. Mid level dry air will work northward during Sunday evening, creating a taper off for a few hours in the precipitation, especially south of I-90. Area that were raining continue to see lighter rain\/drizzle, and some areas that were seeing mix\/snow probably go over to a period of lighter rain for a while. The higher terrain of interior southern NH and MA from the I-495 belt westward stay cold enough for snow, and also are less affected by the dry slot, if at all. Beyond this, the overnight hours to early or mid morning Monday will be when the greatest amount of cold air is pulled into the system from the north, along with additional dynamic cooling from above. This is when snow will overtake the entire region from northwest to southeast in mix\/rain areas, including but lastly Cape Cod, and there will be a temporarily increase in the intensity of precipitation in response to intensifying surface low pressure. This is when most of the snow accumulation will take place east of I-95 and south of I-90. Snow ends by late morning or midday Monday from northwest to southeast as low pressure begins to pull away.<\/p>\n\n\n\n
Total snowfall: Keep in mind that this is for the entire event, and depending on precipitation type, the total snowfall will not be the amount of snow on the ground at any given location. Even in areas that stay all snow to the northwest have a wet snow for a good part of the storm, and compacting will occur there before it flips to a lower water content snowfall later in the storm. Looking for up to 1 inch Outer Cape Cod \/ Islands and immediate South Coast of MA\/RI and eastern CT, 1-3 inches remainder of Cape Cod and MA South Shore to Boston \/ Providence through interior southeastern CT, 3-6 inches in the majority of the I-95 corridor and northern RI to northeastern CT and lower elevations of south central MA as well as the NH Seacoast, and 6-10 inches interior southern NH and the western Merrimack Valley west and southwest through central MA. Highest snowfall occurs in higher elevations.<\/p>\n\n\n\n
Flooding: No major issues, both rivers and coastal areas.<\/p>\n\n\n\n
Wind: Top gusts may reach 50 MPH across Cape Cod early hours of Monday from the northeast. No major wind issues for the remainder of the region.<\/p>\n\n\n\n
Power outages: Moderate risk of power outages in areas where heaviest snowfall occurs due to the higher water content nature of the snowfall for much of the storm. Lower risk of wind-related power outages Cape Cod.<\/p>\n\n\n\n
Post-storm, clearing arrives Monday night and high pressure moves in with fair and chilly weather through the middle of the coming week. A trough dropping out of Canada through the Great Lakes into the Northeast may bring snow showers to the region by later Thursday.<\/p>\n\n\n\n
TODAY: Overcast. Rain\/mix\/snow develops southwest to northeast by midday and continues afternoon with greatest chance of snow interior higher elevations, but also periods of alternating precipitation type closer to the I-95 belt while mostly rain falls in the coastal areas especially south. Highs 35-42 by midday, then slowly but unevenly falling temperatures. Wind NE 5-15 MPH, higher gusts especially coastal areas by late-day.<\/p>\n\n\n\n
TONIGHT: Overcast. Precipitation of varying intensity may stop at times especially south of I-90 where more rain than snow is likely, and will be steadiest I-90 north where more snow is likely, with more of transition to snow working southeastward overnight when precipitation is steadier. Temperatures slowly falling to 28-35 by dawn coldest northwest, mildest coastal plain. Wind NE 10-20 MPH except 20-30 MPH Cape Cod where gusts 40-50 MPH are possible.<\/p>\n\n\n\n
MONDAY: Overcast with snow likely in the morning. Snow ending with breaking clouds afternoon. Temperatures falling to 25-32. Wind NE-N 10-20 MPH, higher gusts especially coastal areas through midday.<\/p>\n\n\n\n
MONDAY NIGHT: Clearing. Lows 13-20. Wind NW 5-15 MPH.<\/p>\n\n\n\n
TUESDAY: Mostly sunny. Highs 27-34. Wind NW 5-15 MPH.<\/p>\n\n\n\n
TUESDAY NIGHT: Mostly clear. Lows 12-19. Wind W up to 10 MPH.<\/p>\n\n\n\n
WEDNESDAY: Mostly sunny. Highs 30-37. Wind W up to 10 MPH.<\/p>\n\n\n\n
WEDNESDAY NIGHT: Mostly clear. Lows 13-19. Wind variable up to 10 MPH.<\/p>\n\n\n\n
THURSDAY: Partly sunny. Chance of late day snow showers. Highs 31-38. Wind W 5-15 MPH.<\/p>\n\n\n\n
DAYS 6-10 (FEBRUARY 2-6)<\/p>\n\n\n\n
Additional snow showers possible with a passing trough on February 2. Generally fair weather expected during the February 3-5 time frame. Another storm threatens the region by the end of the period. Temperatures variable, averaging close to normal overall.<\/p>\n\n\n\n
DAYS 11-15 (FEBRUARY 7-11)<\/p>\n\n\n\n
Storm potentials somewhere early period and again at the end of the period. Temperatures near to slightly below normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
