DAYS 1-5 (MAY 2-6)<\/p>\n\n\n\n
We’re in an unsettled weather pattern, but that term “unsettled” is often misunderstood to mean days of rain, or miserably cool weather, etc. Clarification: Unsettled weather can describe changeable weather with several “systems” – high pressure \/ low pressure \/ fronts – impacting sensible weather conditions. This is also typical of springtime here in New England, whether in a progressive pattern where weather systems move right along, or a blocking pattern where they are in less of a hurry to move much. Over the next 5 days, we’ll see our set-up shift from progressive to blocking, and endure some changes that go along with that transition. Some of you may have been awoken by rumbles of thunder, or in some cases, crashes of it if it the triggering lightning was close enough, as a warm front moved through from west to east, bringing showers and thunderstorms with it. These have exited over the ocean, and our day today will feature clouds breaking for sun at times, except clouds more stubborn near the South Coast with a stronger direct low level moisture feed off the cooler ocean waters. A weak trough of low pressure approaching from the west can trigger isolated showers and a very low risk of a thunderstorm any time this afternoon or evening, but coverage on these is expected to be quite low. We stay in this “warm sector” with a southwesterly air flow through Saturday. It does appear we can make it through the morning and midday hours with minimal shower threat, but I cannot rule a few stray passing ones out completely – so keep this in mind if you have outdoors in your plans (sports, walks, yard sale hopping, etc.). We will have to keep a closer eye out for the development of showers and thunderstorms, particularly west of I-95, during the afternoon hours. A few of these could be strong with an isolated severe thunderstorm not out of the question. These would likely weaken \/ fall apart as they migrated closer to the coast late in the day. Part of the trigger of these will be an approaching cold front. The question the last couple of days has been what the timing of that front will be. It’s been a tough one to answer, but I do think it will slide southward across the region on Sunday, with a shower threat. Also, the timing of that front is critical to Sunday’s temperature forecast. A slower-moving front would allow Sunday to be a warmer day for a while with a cool-down coming later. A little quicker movement on the front will take the warmth out of the picture and Sunday will be a cooler day overall. I’m going for a slightly slow, but not too slow movement, so kind of a split between those 2 potentials. This is part of the evolution of blocking which will then put a closed upper level low over the northeastern US early next week, with cooler, mainly cloudy weather. The next question to answer will be how much rain to expect early in the week. There are some indications that eastern Canadian high pressure – part of the blocking pattern – will be strong enough to keep most rain to our south Monday, but may not quite have that ability to do so during Tuesday. So for now, I’m leaning toward less rain for “day 4” and more for “day 5”. Don’t hang your hat on this outlook yet though, because it’s not high confidence, and updates may very well result in notable adjustments in expectations for those days, but that’s the way it goes here in springtime.<\/p>\n\n\n\n
TODAY: Clouds break for sun at times – least sun South Coast \/ most sun north of I-90. A stray shower and very slight chance of a thunderstorm, especially late-day, west of I-95 \/ north of I-90. Highs ranging from 55-62 Cape Cod \/ Islands to 73-80 inland with warmest north of I-90 \/ west of I-95. Wind S to SW increasing to 5-15 MPH with a few higher gusts.<\/p>\n\n\n\n
TONIGHT: Mostly cloudy. A shower possible early. Fog patches. Lows 55-62. Wind SW 5-15 MPH.<\/p>\n\n\n\n
SATURDAY: Partial sun but lots of clouds. Isolated to scattered showers and thunderstorms will favor areas west of I-95 during the afternoon, with a few storms possibly strong to (isolated) severe. Highs 58-65 Cape Cod, 66-73 remainder of South Coast region, 74-81 elsewhere. Wind SW 5-15 MPH, higher gusts.<\/p>\n\n\n\n
SATURDAY NIGHT: Mostly cloudy. A chance of showers. Lows 50-57. Wind variable 5-15 MPH.<\/p>\n\n\n\n
SUNDAY: Mostly cloudy. A chance of showers. Highs 58-65. Wind N 5-15 MPH.<\/p>\n\n\n\n
SUNDAY NIGHT \/ MONDAY: Cloudy. Chance of rain, favoring southern areas. Lows 48-55. Highs 55-62. Wind NE 5-15 MPH.<\/p>\n\n\n\n
MONDAY NIGHT \/ TUESDAY: Cloudy. Better chance of rain in all areas. Lows 46-53. Highs 53-60. Wind E 5-15 MPH.<\/p>\n\n\n\n
DAYS 6-10 (MAY 7-11)<\/p>\n\n\n\n
While there are indications of blocking continuing, enough of a shift in features should result in a drying trend. Temperatures start out below normal then moderate, more aggressively inland than near the coast.<\/p>\n\n\n\n
DAYS 11-15 (MAY 12-16)<\/p>\n\n\n\n
Current indications are a transition from blocking to progressive, but trough position with a tendency for Canadian cool shots. Brief wet weather interrupting an overall dry pattern.<\/p>\n","protected":false},"excerpt":{"rendered":"
