DAYS 1-5 (MARCH 2-6)<\/p>\n\n\n\n
The very active pattern goes on, but light is at the end of the tunnel (or at the end of the 5-day)! First, low pressure sliding northeastward through the Ohio Valley toward the interior Northeast will redevelop just south and southeast of New England today before moving steadily and quickly seaward. This system brings a swath of rainfall to our region with an atmosphere too mild to support snow, but surface temperatures cold enough so that some of that rain will be in the form of freezing rain from the Worcester Hills to the Monadnock region of southwestern NH – so use extra caution if traveling in those areas. Temperatures will rise above freezing in these areas around mid morning, putting an end to any icing. Rainfall exits our region later this morning and we have a drying trend from midday on, with the potential for some breaks of sun before day’s end. A sliver of high pressure brings dry weather tonight into Friday, but clouds will already be streaming in quickly on Friday ahead of our next storm. When all is said and done, this low pressure system will behave similarly to our last couple more important storm systems, with a primary low heading for the Great Lakes and redeveloping to move out just south of New England. But as has been the case all winter and even with a more recent pattern change to slightly colder, we don’t have quite the setup for just a snow event, so there will be a variety of precipitation, with most snow to the north and far less to the south where more rain will be involved. The rain-snow line is a little tricky with this, with even at this stage some significant differences in guidance, but I’m not really changing my initial idea from yesterday, which will be reflected in my snowfall amounts in the detailed forecast). Steadiest precipitation window is 12 hours – midnight Friday night to noon Saturday. As slightly colder air overtakes the region behind the storm, a period of scattered snow showers will be with us from Saturday afternoon through Sunday morning as an inverted trough of low pressure (basically the remains of the primary low pressure area) swings through our region from northwest to southeast. The next phase of our late winter pattern emerges Monday with low pressure to the east, high pressure to the west, and a drier but chilly northwesterly air flow.<\/p>\n\n\n\n
TODAY: Overcast this morning with rain likely (some freezing rain in portions of north central MA to southwestern NH for a while early), tapering off by late morning. Mostly cloudy this afternoon but a few breaks of sun are possible before the end of the day. Highs 40-47. Wind variable up to 10 MPH becoming NW 5-15 MPH later in the day.<\/p>\n\n\n\n

FRIDAY: Increasing clouds. Highs 36-43. Wind N-NE up to 10 MPH.<\/p>\n\n\n\n
FRIDAY NIGHT: Overcast. Snow arrives west to east but mixed with sleet\/rain South Coast which then advances north toward I-90 overnight. Lows 28-35. Wind NE to E 5-15 MPH, higher gusts.<\/p>\n\n\n\n
SATURDAY: Overcast through midday with snow southern NH and far northern MA, snow and sleet possibly mixed with rain Cape Ann MA down 128 to I-90 belt, and some mix but mostly rain to the south. Expected snow accumulation from little or nothing along the South Coast to a coating to 2 inches just away from immediate South Coast to the MA South Shore, 2-4 inches Boston (maybe under 2 Logan Airport) to Cape Ann MA westward along the I-90 belt, 4-8 inches interior northeastern MA through central and north central MA northward through southern NH except possibly under 4 inches at the NH Seacoast. Mostly cloudy with lingering snow showers during the afternoon. Highs 31-38. Wind E-NE 5-15 MPH, higher gusts.<\/p>\n\n\n\n

DAYS 6-10 (MARCH 7-11)<\/p>\n\n\n\n
Overall set-up features low pressure east of New England and high pressure from Canada to the Midwest through at least mid period with a generally dry and chilly northwesterly air flow, but not immune to a disturbance or two bringing a few snow showers. Pattern may relax enough to allow the next low pressure system from the west to approach by the end of the period.<\/p>\n\n\n\n
DAYS 11-15 (MARCH 12-16)<\/p>\n\n\n\n
Return to unsettled pattern for mid March including some lingering threats of wintry precipitation. Temperatures near to below normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
