Saturday Forecast

DAYS 1-5 (JUNE 22-26)
A nice weekend in general, but today will feature a gusty breeze and we’ll also pop some clouds especially later in the day as what ground heating we do get interacts with cold air above and a weak trough moving north to south behind the recently-departing low pressure system. These clouds may lead to a few isolated showers and even a brief thunderstorm, but any that occur will be small and rather quick-moving. High pressure settles in for a very nice Sunday and hangs on for Monday as well, with a gradual warm-up, but still we lack any hot weather. Weak low pressure tracking eastward will pass north of southern New England and drag a quick warm front / cold front combo across our area Tuesday, with some unsettled weather, before weak high pressure returns with fair weather Wednesday.

    1. I don’t think so. Most of the showers will form in the clearer air north of the plume.

  6. According to Barry, we “may” have our first 90 degree day late next week. I guess it has to come eventually. 🙁

    2. Bad thermometer aside, Boston may never get to 90 in June. They’ll need “luck”. 😉

  7. Thanks TK.

    SNE gets a couple of days like today every year, and they were always some of my favorites. Cold pools aloft with very steep lapse rates. You should see fairly widespread showers and thunderstorms this afternoon, several of which will contain hail. Generally pea sized or less, but storms will tend to pulse up and down pretty quickly, and when they pulse up you can briefly get borderline severe (quarter size) hail. Lots of dry air in the low levels (“inverted V” soundings) will also favor strong downdraft wind gusts, again mainly sub-severe but locally 40-50mph.

    1. One of my favorite “cool pool aloft” days was July 1 1988. That was a hot summer overall (through August 15) but we had a pattern shift briefly that brought down that and created some nice instability thunderstorms. I remember playing street hockey at my high school that afternoon (Friday) and seeing the dark bases to the north with lightning about the time we were wrapping up the game. The brunt of that storm never got to where I was but we did have several showers pass by. We had a weekend similar to what this weekend is like on July 2-3 and then we started into the hotter pattern on July 4 that was pretty much non-stop until a tornado watch day and cold front marked a major pattern change in mid August, then we were much cooler for late August through summer’s end.

      1. I can remember a couple times where such showers would go over me and I’d see some small hail. More often though it’s the frustration of seeing one of those fast pulsing cores miss you by a couple of miles, knowing that’s where the real fun is happening!

  9. WxW ans TK….I’d take this cool pool above for weeks on end. It is an absolutely glorious day.

    1. As much as I love summer heat I do love these cool pools quite a lot. They tend to produce very high-visibility showers & storms, easy to follow (traffic aside). Even though they don’t last too long they can produce brief good shows and wonderful cloudscapes.

  10. Thank you, TK.

    Not a weather-appropriate video (more appropriate for the dead of winter), but I absolutely love this song; one of Bob Marley’s last songs. He performed it at the Hynes Convention Center in September 1980. A few days later he collapsed while jogging in Central Park, and spent 7 months getting progressively worse as his cancer spread. He was and is a legend.

  11. Dark and very tall clouds to our east. More dark clouds heading into our area from the northwest…Mansfield area with a lightning strike or two.

  14. So, I saw a story on CNN about heat in Europe next week.

    The 12s Euro certainly confirms this over western areas of Europe.

    A 500 mb ridge maxes out just over 597 dm in a few days and a 25C, 850mb contour covers a good part of Spain and some of France with a 20C contour continuing northward into southernmost England.

    Wow, good luck to that part of the world with that ……

  15. Must have been rain here. I took the deck umbrella down before we headed out and it was wet when I just put it back. Nothing registered on the rain gauge though. Uxbridge got hail from what I’m reading

  17. I guess pembroke had an impressive hail storm according to my wife & son . Wind as well chairs & tables tipped right over . I was wrapping up a job in Duxbury where it poured out no hail.

    1. Wow looking at videos from around pembroke holly molly that’s a lot of hail – wow .

  18. Just a Trace at Logan today. Ominous clouds for awhile this afternoon though. There was quite a bit of water in my basement from Friday morning’s downpour.
