DAYS 1-5 (APRIL 13-17)

There are alot of little details to work out this week with respect to sea breezes and a frontal boundary in what would otherwise be a pretty warm pattern. Today, the front goes by as a warm front early on with no more than a few lingering light showers around this morning. Another disturbance may bring a late-day or evening shower especially to northern MA and southern NH. In between, we may see breaks of sun but clouds will be largely dominant today, limiting the temperature rise to the 60s in most areas (lower 70s possible where enough sun occurs). Exception (of course): South Coast where a southwest wind cools that area due to passing over the ocean water just south of New England, and you’ll see that repeat again on the regionally warmer days this week when the wind is from that direction. One of those will be Tuesday, but with more sunshine, so away from the cooling influence at the South Coast, high temps of 70+ seem likely. However, this may be interrupted by a sea breeze in the afternoon especially from the MA North Shore to the NH Seacoast, where it could tumble back to the 50s in short order. Wednesday is the day with a bit more uncertainty. Some of our newer (but so far fairly reliable) short range guidance suggest that after a disturbance passes by Tuesday night, which may bring a shower, that its cold front pivots south and southwest as a back-door cold front being given an extra push by high pressure in eastern Canada. When this possibility presents itself and we’re at this time of year with this particular set-up, I tend to lean to the cooler side of the warmer, and I’ll do that at least for eastern areas for Wednesday, while inland areas can warm up much more so long as the frontal boundary doesn’t move even further inland. It looks like we’ll get a push of the boundary back to the north and east as a warm front Thursday when we have a warmer potential (except modified South Coast temps again) into Friday, before another disturbance brings the front back our way with a shower and thunderstorm threat potential on Friday. Confidence in the forecast detail is much lower by then, so keep up with the updates during the week!

TODAY: Mostly cloudy. A shower possible, mainly late-day and favoring southern NH / northern MA. Highs 48-55 Nantucket / Martha’s Vineyard, 55-62 South Coast, 63-70 most other areas except 66-73 interior valleys. Wind SW 5-15 MPH, higher gusts.

TONIGHT: Variably cloudy. Chance of a shower southern NH and northern MA in the evening. Lows 48-55. Wind SW 5-15 MPH.

TUESDAY: Mostly sunny to partly cloudy. Highs 55-62 South Coast, 63-70 MA South Shore and Cape Ann, 71-78 elsewhere. Temps can fall sharply to 50s NH Seacoast and MA North Shore in the afternoon. Wind SW 5-15 MPH, potentially shifting to E NH Seacoast and MA North Shore.

TUESDAY NIGHT: Variably cloudy. A shower possible, favoring southern NH and northern MA. Lows 48-55. Wind SW 5-15 MPH.

WEDNESDAY: Partly sunny. Highs 55-62 South Coast, 62-69 MA South Shore and Cape Ann, 70-77 elsewhere, but likely turning sharply cooler at least NH Seacoast and eastern MA during the day. Wind SW 5-15 MPH likely shifting to NE and E at least NH Seacoast and eastern MA during the day.

WEDNESDAY NIGHT: Variably cloudy. Chance of a shower. Lows 45-52 except 52-59 interior southern MA. Wind variable under 10 MPH.

THURSDAY: Variably cloudy. Chance of a shower. Highs 55-62 South Coast, 63-70 MA South Shore and Cape Ann, 71-78 elsewhere. Wind variable becoming SW 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Lows 52-59. Wind SW up to 10 MPH.

FRIDAY: Variably cloudy. Chance of showers and thunderstorms. Highs 53-60 South Coast, 61-68 MA South Shore and Cape Ann, 69-76 elsewhere. Wind SW to variable 5-15 MPH.

DAYS 6-10 (APRIL 18-22)

Battle zone here between cool high pressure in eastern Canada, a warmer high pressure ridge to our south, with a frontal boundary providing a path for disturbances in between. Leaning cooler April 18, warmer April 19, then a stronger push of cooler air from the north and west after that which may be marked by showers and thunderstorms later April 19 followed by drier, cooler weather early next week.

DAYS 11-15 (APRIL 23-27)

One ore two opportunities for wet weather in a variable temperatures pattern during this period.

  2. Thanks TK !

    Wordle: 5 (where did they find this word?)

    I only got it because I had 4 letters after 4 and just kept plugging in a 5th letter until it took. Everything else didn’t make a word.

    1. I did the same except I plugged something on 5th guess that turned out to be a wod I never heard of. So, 6 for me. Crazy word.

      1. Great work. I have 4 guesses so far with four letters two with one confirmed in correct spot and another that can only go in one place and I have no clue. I had a feeling it is a little known word. Not sure why nyt does this but wish they’d just reuse words from when Wordle first started. Time to write and ask them

  10. Wordle 3 today. Kind of a strange one for sure… only had 3 after 2, with only second in right place, couldn’t find anything to fit though until it popped in to my head.

  11. The temperature is 57 F here.

    I got Wordle in 4. I’m familiar with this word, but Googling around today I found another use of it. I can’t find a link to this use that won’t give it away in the URL. 🙂

  12. Wordle 5 and turns out it’s a word I am familiar with so no idea why it took so long.

    How does a birthday party sound in Tom’s and my five car??

    1. There is a reason I am a huge fan of the sonos sound system. After trying a few tests, Sonos is sending me a new Roam. 🙂

      Now I’ll have music on the deck
