DAYS 1-5 (MARCH 13-17)
\nAdjustment being made with this update for a slightly further west track of the center of low pressure for the Tuesday storm. This introduces a little more warning aloft especially from the Boston-Providence corridor southeastward. Some guidance has this even further west but not going with this scenario at this time. Regardless, the storm will be intensifying rapidly as it comes across far southeastern New England and will have a large impact, even where it is not all snow. Wind and coastal flooding concerns remain, along with blizzard conditions northwest and west of the storm track as it passes. This should be a very strong wind event for the entire area. The difference between yesterday’s thinking and today’s, in additional to more mix\/change to sleet\/rain close to Boston-Providence, is a period where the wind shifts to southerly over Cape Cod as the low center would track west of there. This more westerly track also introduces the probability of a dry slot, or precipitation-free area that moves up from the south during the evening Tuesday and basically shuts things down along and east of the track of the center of low pressure, while snow would continue to the west before everything tapered off later. Also still expecting some snow showers Wednesday with the upper low still, but not seeing this as an event with anything more than minor additional accumulation. Fair weather is back for Thursday and Friday but with below normal temperatures as the cold pattern continues.
\nTONIGHT: Thickening overcast. Snow South Coast before dawn. Lows 22-30. Wind light variable.
\nTUESDAY: Overcast. Snow area pushes north quickly in the early to mid morning and becomes heavy at times, first in RI and southern MA then the remainder of MA into NH, changes to sleet then rain Cape Cod and Islands, into southeastern MA and southern and eastern RI. Thunder is possible. Best guess on where the line gets to is about Boston and maybe immediate Metro West and southward down I-95 and possibly onto Cape Ann MA as well. Highs range from 25-30 interior MA and southern NH westward, ranging to 40-45 Cape Cod and Islands later in the day. Wind NE increasing to 20-35 MPH interior, 30-45 MPH coast, but much higher gusts at times.
\nTUESDAY NIGHT: Rain\/sleet ends where the changeover occurred and possibly into interior eastern MA and southeastern NH, while lighter snow continues in areas to the west of the track of the low, tapering off later at night. Snow accumulations ranging widely from 1-3 inches outer Cape Cod and Nantucket to 3-6 inches remainder of Cape Cod and Martha’s Vineyard, 6-12 inches southeastern MA, southern and eastern RI including from Boston to Providence, 12-18 inches elsewhere except 18+ inches in pockets of interior MA and southern NH westward. Temperatures may rise slightly over southeastern MA briefly and remain nearly steady elsewhere before falling to lows of 22-30 all areas overnight. Wind N to NW 15-35 MPH with higher gusts except briefly SE to SW over parts of southeastern MA before shifting to NW there.
\nWEDNESDAY: Mostly cloudy. Snow showers. Additional minor accumulation possible. Highs 25-35. Coldest interior areas. Wind NW to W 10-20 MPH.
\nTHURSDAY: Partly cloudy. Lows 10-20. Highs 25-35.
\nFRIDAY: Mostly sunny. Lows 15-25. Highs 30-40.<\/p>\n
