DAYS 1-5 (FEBRUARY 21-25)<\/p>\n\n\n\n
An area of high pressure slides eastward across the Middle Atlantic today but extends far enough north to give us a nice winter day here in New England. Low pressure will cross New England later Monday bringing unsettled weather with it. For here in southeastern New England, precipitation may come with an initial burst of snow for areas mostly north of I-90 with an initial push of instability and overrunning of warmer air above air that is still quite cold. The surface warm front associated with this system may never make it completely across the WHW forecast area before its cold front sweeps through during the evening. This occluding frontal system will produce a swath of precipitation from west to east during the afternoon and evening, starting out as snow with minor accumulation in the I-95 belt northwestward, and possibly brief rain\/snow mix but otherwise mainly rain in areas to the southeast. Once the main front has swept through in the evening then drier air will return and set us up for a decent day on Tuesday, although a disturbance passing north of the region means that we’ll have some high and mid level cloudiness to deal with. Wednesday looks like the pick of the upcoming week with more sunshine, and the mildest air we’ve had for a while. It would end up even warmer if not for existing snow cover, but look for most areas to easily make the middle to upper 40s, which will feel quite nice in combination with the late February sun. A cold front will sweep across the region in the early hours of Thursday with limited moisture to worth with, so just look for some cloudiness and perhaps a brief shower of rain as it will still be fairly mild. Temperatures during the day Thursday will not move all that much as the arrival of cold air and the warming of the sun essentially balance each other out.<\/p>\n\n\n\n
TODAY: Sunny. Highs 28-35. Wind NW 5-15 MPH.<\/p>\n\n\n\n
TONIGHT: Increasing clouds. Lows 16-23. Wind variable under 10 MPH.<\/p>\n\n\n\n
MONDAY: Cloudy. Brief burst of snow possible northern MA and southern NH mid to late morning with a dusting or a coating of accumulation possible. Precipitation arriving west to east during the afternoon as snow from the I-95 belt northwest and mix\/rain to the southeast before changing to rain all areas except may remain mixed with snow in higher elevations of north central MA and southwestern NH. Snow accumulation of a coating to 1 inch possible in the I-95 belt and 1-2 inches possible I-495 belt north of I-90 northwestward. Highs 34-41. Wind variable up to 10 MPH early, then S increasing to 10-20 MPH with higher gusts.<\/p>\n\n\n\n
MONDAY NIGHT: Mostly cloudy start with any rain exiting early, then clearing. Watch for the formation of black ice on untreated surfaces. Lows 25-32. Wind W 5-15 MPH.<\/p>\n\n\n\n
TUESDAY: Partly sunny. Highs 37-44. Wind W 5-15 MPH.<\/p>\n\n\n\n

THURSDAY: Sun and passing clouds. Temperatures steady 35-42. Wind W 10-20 MPH.<\/p>\n\n\n\n
DAYS 6-10 (FEBRUARY 26 \u2013 MARCH 2)<\/p>\n\n\n\n
Stronger push of cold air February 26 but high pressure builds in with fair weather while a disturbance passes well south of New England. A little uncertainty beyond this as some guidance brings disturbances and unsettled weather into the region over the February 27-28 weekend with a larger storm potential in the first couple days of March, while other guidance keeps the weekend drier and brings unsettled weather in for the start of March. Leaning toward the second solution for now but definitely more re-evaluation needed as I am not sure how this evolves yet.<\/p>\n\n\n\n
DAYS 11-15 (MARCH 3-7)<\/p>\n\n\n\n
Very low confidence out this far. West to northwest flow pattern expected. Best chance for unsettled weather comes around the middle of the period.<\/p>\n\n\n\n
