DAYS 1-5 (FEBRUARY 14-18)<\/p>\n\n\n\n
Your Valentine’s Day weather will be mostly dry, but windy and on the cold side, as a healthy northwesterly air flow exists between eastern Canadian low pressure and an area of high pressure building our way from the Great Lakes and Midwest. The air flow is carrying some moisture from the Great Lakes region this way, and a little band of light snow showers can form and move across some areas as we go into midday and afternoon. High pressure builds closer and over the region tonight to shut down the wind, but make for a very cold night due to radiational cooling. Dry weather is good for anybody with evening plans that take them outside, but you will want to be aware that lingering icy patches can exist where they were not removed \/ treated \/ sublimated by dry air. And now the focus shifts to the weekend event. I haven’t changed my ideas too much on this, but attempting to refine the forecast a bit more here. One surge of moisture heads our way ahead of a warm front on Saturday, with a few to several inches of snow expected Saturday afternoon and night. Timing is such that we should get through most of the daylight hours of Saturday before the snow reaches the entire region, and it may even wait until nightfall to reach areas further south and east. The big key to the forecast is the track of low pressure and the movement, or lack of movement, of the warm front ahead of it. Model forecast often struggle with this, trying to warm it up too quickly, but cold air is hard to dislodge from near the ground, and while it warms aloft rather easily as a primary low pressure area takes a track into the New York State area, the cold air nearer the ground sets up a sleet \/ freezing rain situation. We’ll have to watch for this, and then track the surface temperature to see where it can get above freezing for just rain, and stays at and below freezing for an icing situation. If the layer of cold air is dense enough, instead of freezing rain, you see sleet. So that delicate temperature profile and resultant precipitation pattern is what to look at during the overnight Saturday night through Sunday portion of this drawn-out storm system. The potential is highest for snow going to a longer period of sleet away from the coast and well inland, a period of freezing rain in most other areas, but warming enough above freezing to occur non-freezing rain closer to the coast, especially the South Coast to Cape Cod. After all this, as low pressure redevelops nearby then moves offshore, enough cold air can come back for a flip to sleet \/ snow northwest to southeast, at least for a brief time, before it comes to an end. This would occur Sunday evening. Behind the storm system, its influence will still be with us Monday in the form of strong, gusty wind, and cold air, as dry weather returns. This windy and cold set-up lasts through Tuesday too as the storm becomes quite strong while moving through Atlantic Canada.<\/p>\n\n\n\n
TODAY: A sunny start then a sun\/cloud mix and a slight chance of passing snow flurries, favoring areas west and southwest of Boston. Highs 28-35. Wind NW 10-20 MPH, gusts above 30 MPH, diminishing later in the day.<\/p>\n\n\n\n
TONIGHT: A few passing clouds early, a clear interlude, then increasing high clouds overnight. Lows 5-12 except 12-19 South Coast. Wind NW 5-15 MPH early becoming calm.<\/p>\n\n\n\n
SATURDAY: Filtered to dimmed sun as high clouds thicken up in the morning. Lowering overcast afternoon – late day snow likely, especially west of I-95. Highs 22-29. Wind N up to 10 MPH.<\/p>\n\n\n\n
SATURDAY NIGHT: Overcast. Snow evening into overnight with accumulation of 1 to 3 inches south of I-90 and 3 to 6 inches elsewhere except 6 to 8 inches in some locations of southern NH and north central MA. Snow to sleet to freezing rain \/ rain transition begins south to north late evening \/ overnight with icing conditions first away from the immediate South Coast up to the I-90 belt with higher probability to sleet to the north. Temperature rising slightly to 28-35, mildest along the South Coast. Wind N up to 10 MPH evening, staying that way over interior valleys and shifting to E 5-15 MPH elsewhere, especially coastal areas, overnight. <\/p>\n\n\n\n
SUNDAY: Overcast. Precipitation continues – transition from freezing rain to non-freezing rain works from South Coast into the I-90 belt but takes longest in valleys, sleet to freezing rain in areas to the north with a lower chance of getting to non-freezing rain, resulting in additional sleet accumulation and ice accretion. Highs 28-35 north of I-90, 35-42 I-90 south. Wind E to SE 5-15 MPH, except interior valleys and portions of northern MA and southern NH see calmer conditions or a N drift.<\/p>\n\n\n\n
SUNDAY NIGHT: Cloudy early with rain\/ice likely turning to snow with a possible small accumulation before ending. Breaking clouds overnight. Lows 15-22. Wind becoming NW 10-20 MPH with higher gusts.<\/p>\n\n\n\n
MONDAY (PRESIDENTS DAY): Sun\/cloud mix. Chance of a passing light snow shower. Highs 23-30. Wind NW 15-25 MPH with gusts 30+ MPH.<\/p>\n\n\n\n
MONDAY NIGHT: Partly cloudy. Lows 11-18. Wind NW 10-20 MPH, higher gusts.<\/p>\n\n\n\n
TUESDAY: Partly sunny. Highs 20-27. Wind NW 10-20 MPH, higher gusts.<\/p>\n\n\n\n
DAYS 6-10 (FEBRUARY 19-23)<\/p>\n\n\n\n
Watching a snowstorm potential in the February 20-21 time frame – leaning toward an offshore evolution and more of a side-swipe than a bigger hit, but the latter cannot be discounted as a potential this far in advance. Generally dry weather just before this threat and returning again after. Temperatures below normal.<\/p>\n\n\n\n
DAYS 11-15 (FEBRUARY 24-28)<\/p>\n\n\n\n
Watching the February 26-28 period for a potential winter storm impact. Temperatures below normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
