DAYS 1-5 (FEBRUARY 23-27)

Storm day. And it’s a decent winter storm with bands of heavy snow interspersed with lighter areas, typical for an intensifying storm, which is passing southeast of our region today. And as it does so, the bands of heavier snow with lulls of lighter snow will continue through the morning before a taper-off progresses west to east during the afternoon, with the result being heaviest amounts southwest of Boston, but still significant amounts in much of the remainder of the region, with relative low(er) spots in southeastern NH and far northeastern MA due to less time in heavier snow, and over Outer Cape Cod and especially Nantucket due to wetter snow. Minor to moderate coastal flooding occurs at east-facing and north-facing locations mid to late afternoon around high tide hours, limited by astronomical tides that are not that high, thankfully. Where heavy snow and strong wind combines there is a higher risk of power outages. The area most likely to experience blizzard conditions (3+ hours of visibility 1/4 mile or less due to falling and/or blowing snow, sustained wind or frequent wind gusts of 35 MPH or greater) will be from Cape Ann through Boston to southeastern MA. With intense bands of snow, thunder is possible, with highest chance of this occurring south of Boston until midday. The storm exits tonight and as clean-up and recovery progress on Tuesday it will do so with fair weather as high pressure moves in. But we are still in an active pattern and the next low pressure system is coming our way for Wednesday via the Great Lakes. This system is expected to be minor in comparison, bringing some snow, mix, and rain, with up to a few inches of snow favoring areas mostly north of I-90. Today I’m a little more optimistic about another break Thursday before the next storm system, passing just to the south based on current indications, brings a snow and mix chance back to us on Friday.

TODAY: Overcast. Snow, heavy at times morning, including the chance of thunder, especially south of I-90. Snow tapering off west to east afternoon. Accumulations of 10-15 inches in general, but some areas of under 10 inches can exist, favoring far northeastern MA and southeastern NH, as well as Outer Cape Cod and especially Nantucket. A band or two of accumulation of 15-20 inches is most likely from the Plymouth MA to Providence RI areas into parts of eastern CT. Highs 27-34, coldest well inland, mildest Cape Cod. Wind NE 15-35 MPH, gusts 40-60 MPH, strongest along the coast.

TONIGHT: Clouds break. Lows 20-27. Wind N 15-25 MPH with higher gusts evening, diminishing overnight.

TUESDAY: Mostly sunny. Highs 30-37. Wind NW 5-15 MPH.

TUESDAY NIGHT: Clouding up. Lows 21-28. Wind W under 10 MPH.

WEDNESDAY: Cloudy. Snow of 1 to 3 inches north of I-90, a mix of snow/sleet/rain to the south with less than 1 inch of snow. Highs 32-39. Wind variable 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Precipitation ends. Lows 25-32. Wind NW up to 10 MPH.

THURSDAY: Partly sunny. Highs 35-42. Wind N up to 10 MPH.

THURSDAY NIGHT: Cloudy. Lows 22-29. Wind NE 5-15 MPH.

FRIDAY: Cloudy. Chance of mix/snow. Highs 31-38. Wind NE 5-15 MPH.
