DAYS 1-5 (APRIL 22-26)<\/p>\n\n\n\n
Happy Earth Day 2021! Take care of our planet! It is our only home…. Well, this year’s edition of Earth Day here in southeastern New England may as well be on a day in late February or early March for how it’s going to feel. The last couple days’ taste of the warmer side of spring, ending with yesterday’s showers and thunderstorms, is now a memory as we’ve had a strong cold front pass by, opening the door to a strong shot of polar air from Canada on gusty northwesterly winds. The mechanism pulling this air into our region at the surface is the pressure gradient between the now stronger low pressure wave that went by us yesterday as it travels through eastern Canada and a high pressure area sliding southeastward from the Ohio Valley toward the Middle Atlantic States. Other than a narrow ocean-effect band of stratocumulus clouds just north of the tip of Cape Cod, and some strips of similar clouds from the mountains making it into southwestern NH, central MA, and one closer to the South Coast, much of the region is starting out with sunshine despite the blustery and cold conditions, but there is plenty of even colder air aloft and not only will we have additional cumulus & stratocumulus clouds coming in from the northwest today, but additional clouds will fill in any clear spaces as the sun heats the ground below. This is a process we see on a fairly regular basis here in the Northeast, and it most frequently happens in spring and sometimes autumn. There will be enough instability that a few rain and even snow showers may fall from some of these clouds as we go through the day and into early this evening, before they finally start to break up and dissipate. Friday’s weather will still feature a gusty breeze, though less strong that today, and we’ll have more sunshine as a downsloping westerly wind will dry the air and warmer air above leads to less cloud development. As high pressure moves offshore during Saturday we’ll see the wind flow go from west to southwest and we’ll warm nicely, except for typical cooler South Coast regions. But with things on the move with this week’s zonal pattern, the next low pressure area will be making a run at the region by Sunday, which looks like a wet, windy, and chilly day, but any rain is needed, as we remain in a significant deficit. This system will move beyond the region by Monday, a day that will be breezy and drier but on the cool side as well…<\/p>\n\n\n\n
TODAY: Sun\/cloud mix morning. Mostly cloudy afternoon with a passing rain or snow shower possible, favoring southern NH and northern MA. Highs 43-50. Wind NW 15-25 MPH, gusts 30-40 MPH.<\/p>\n\n\n\n
TONIGHT: Variably cloudy. Slight chance of a rain or snow shower early. Lows 28-35. Wind W 10-20 MPH and gusty, diminishing overnight.<\/p>\n\n\n\n
FRIDAY: Partly sunny. Highs 55-62. Wind W 10-20 MPH, gusts up to 30 MPH.<\/p>\n\n\n\n
FRIDAY NIGHT: Mostly clear. Lows 40-47. Wind SW 5-15 MPH.<\/p>\n\n\n\n
SATURDAY: Sun and high clouds. Highs 65-72, cooler South Coast. Wind SW 5-15 MPH.<\/p>\n\n\n\n
SATURDAY NIGHT: Increasing clouds. Lows 47-54. Wind S to SE 5-15 MPH.<\/p>\n\n\n\n
SUNDAY: Cloudy. Rain likely. Temperatures steady 47-54 or may fall slightly. Wind E 10-20 MPH and gusty.<\/p>\n\n\n\n
SUNDAY NIGHT: Mostly cloudy. Lingering drizzle and possible rain showers early. Lows 40-47. Wind N 10-20 MPH and gusty.<\/p>\n\n\n\n
MONDAY: Partly sunny. Highs 52-59. Wind NW 10-20 MPH with higher gusts.<\/p>\n\n\n\n
DAYS 6-10 (APRIL 27 – MAY 1)<\/p>\n\n\n\n
Zonal (west to east) flow pattern starts to transition to blocking again\u2026 Similar to a recent blocking pattern, we’ll be on the dry side of it with high pressure dominating our weather with mild to warm days which will feature coastal sea breezes at times.<\/p>\n\n\n\n
DAYS 11-15 (MAY 2-6)<\/p>\n\n\n\n
A general blocking pattern should remain in place, but slow movement of weather systems will occur and we may end up with low pressure south of our region and an increased chance for cloud cover and eventually rainfall. Low confidence outlook at this time.<\/p>\n","protected":false},"excerpt":{"rendered":"
