DAYS 1-5 (MAY 3-7)

Upper level low pressure holds control over our weather for 3 more days. As it spins its way east southeast across the region, a new surface low will form to our south and slide northeastward to well east of the region between tonight and early Friday. This will help turn our wind more from the east and eventually northeast, then north as the system moves away. Occasional shower chances continue, with the window of highest opportunity being from this afternoon through midday Thursday. Additional diurnal showers can develop Friday with more sun’s heating. Any showers that are born of tall enough clouds can contain graupel or small hail due to the much colder air aloft and the size of the precipitation not allowing it to melt back to rain before reaching the ground. This weekend we will be rid of the upper low with high pressure building in. This will give us dry weather with a milder trend, especially away from the coast. Enough cool air lingers aloft for the development of fair weather clouds on Saturday but these should be largely absent from Sunday’s sky.

TODAY: Partly sunny, then mostly cloudy. Scattered showers this afternoon, some of which can be mixed with graupel or small hail. Drizzle may develop in some eastern coastal areas by evening. Highs 54-61, coolest coast. Wind E 5-15 MPH.

TONIGHT: Mostly cloudy. Chance of showers and drizzle. Lows 43-50. Wind NE 5-15 MPH.

THURSDAY: Mostly cloudy. Chance of showers and drizzle. Highs 46-53. Wind NE 5-15 MPH, higher gusts especially in eastern coastal areas.

THURSDAY NIGHT: Mostly cloudy. A passing shower possible. Lows 40-47. Wind N 5-15 MPH.

FRIDAY: Variably cloudy. Chance of showers. Highs 51-58. Wind N 5-15 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 41-48. Wind N 5-15 MPH.

SATURDAY: Partly cloudy. Highs 60-67, coolest eastern coastal areas. Wind N 5-15 MPH.

SATURDAY NIGHT: Clearing. Lows 43-50. Wind NW up to 10 MPH.

SUNDAY: Sunny. Highs 65-72 except cooler coastal areas. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (MAY 8-12)

High pressure brings dry and milder weather early to mid portion of this period, then an approaching trough and frontal system from the west brings back the chance of unsettled weather later in the period.

DAYS 11-15 (MAY 13-17)

Drier pattern returns with a period of more seasonable temperatures that then trend cooler again later in the period.

  5. Thunderstorm with frequent lightning as we approached Bermuda this morning. Now that we’re in port? Mostly sunny and 72 degrees at 9 am.

  9. Though I’m not crazy about being caught under upper level low pressure in Spring, having it not south of us and therefore getting some good cumulus cloud development and spokes of showers/storms has been somewhat entertaining.

    1. In fact, there already are some dark cumulus around and I can see one definitely releasing some rain nearby.

      2. Thank you Vicki of thinking of me. You know I Iove to look at the sky. And thank you for sending all of us that beautiful photo. Yesterday I didn’t see any clouds like that here but it did get very dark and we got a brief thundershower. But later as I was having my evening tea I enjoyed watching a lovely sunset with various colors – orange, pink, brown and some patches of blue. It looked rather weird but still beautiful.

  12. Thanks TK
    The first three days of May is nothing like the first three days of May 2001 when the month started off with a heat wave.

  13. Dry/stable air has the entire South Coast mostly sunny now while abundant stratocumulus fill the remainder of the region’s sky. This trend will continue for a bit then we should see more of a mix/up as the upper low center shifts and the new surface low gets going to the south.

  14. Jean, goldfinches are amazing. We have such wonderful tropical-looking birds in New England. Any visitor I’ve ever had from Northern Europe is amazed by them. Needless to say, there are no colorful birds in Northern Europe, at least not the kinds of colors we see here in orioles, goldfinches, cardinals, bluebirds, blue jays, and even house finches.

    What’s really interesting about goldfinches is how late in the season they have their families. Often in August and September. In fact, they sometimes have their young chicks around the time red-winged blackbirds migrate south.

  15. Today has a little bit of an autumn feel to it. Obviously not the light or sun angle. The autumnal feel may be further accentuated tomorrow, as we tumble a bit in temperature. We’ll know soon enough, however, that it’s May. Looks like some 60s and perhaps 70s on tap, from the weekend on. We’ll see.

    1. While I understand that view point, I can’t get the autumnal feel from it. I see too much emerging green (no color changing, falling leaves). I see too much blooming of flowers (not bushes dropping their last foliage in preparation for winter slumber). And it smells vernal, not autumnal. That’s a big thing for me. The air. The scent.

      This, to me, is SPRINGTIME in New England. 🙂 And I love it.

  16. Guidance (both short range and medium) has done a very good job over the last few days depicting the scenario with the upper & surface lows in their simulations. There has been very little change in the guidance run to run and overall during these days. And we know that guidance can struggle mightily in these blocking-type set-ups.

  17. As the axis of low pressure shifts to the south and the surface low to the south takes over, a ribbon of low clouds as wheeling coastward and is already onto the NH Seacoast. This is a lower layer of clouds than what’s out there in most of the area now and should overspread the entire region through tonight and early tomorrow.

  18. I love our little goldfinches. I feed them all winter but we had mice finding their way in the garage so I can’t feed them now. They have the sweetest little chirps.

    Joshua. I can’t recall if you use FB. I have fed and watched birds for decades but never realized how large our variety is. Wildlife of Worcester county is an amazing FB moderated and run by a friend out this way. I highly recommend it

  19. TK, regarding your point on scent, I agree. It is different now. But, regarding flowers, we’ve entered an in-between period, at least where I am. Practically all the early blooms in the Esplanade are gone or about to go. Now this does change in late May, early June, when the summer flowers burst open, and they stay much longer than, say, daffodils, cherry blossoms, magnolias, and tulips. But for now, it’s actually not very flowery along the banks of the Charles (both the Cambridge and Boston sides). It is very green, however, and the leaves on the trees are a beautiful shade of green.

  20. I used to think that winter was the gloomiest season with the least amount of sunshine. I’m beginning to wonder if spring is that season.

    The sunniest? Summertime obviously. 🙂

      Over the last two days our observer at Canaan Mountain Summit in Tucker County (elevation 3,715ft) recorded 15.9 inches of snow. He has been an official observer since July of 2002 and he never seen this much snow in the month of May!

    1. I should really say five people cheated death there….the police officer on foot, the driver of the car that was pulled over and got hit, the approaching car that slammed on his brakes to narrowly avoid a head on collision, and the two teens in the car that lost control going 120 mph.

      Incredible.
