DAYS 1-5 (AUGUST 1-5)
As August gets underway we’ll be under the influence of high pressure which had its origins in Canada and has some drier and slightly cooler air with it, giving the region a break from the humid heat that dominated the last few days of July. We’ll have to watch for a few showers near a sea breeze boundary this afternoon but overall it will be a dry day. As we get into the weekend, the high will slip offshore allowing the humidity to bump up somewhat, but a trough will slide through the region during this time, maybe kicking off a shower or thunderstorm in a few areas. Behind this another high pressure area will build in with the air quite comfortable again by Monday.
Forecast details…
TODAY: Mostly sunny to partl cloudy. Risk of an isolated afternoon shower southeastern NH, eastern MA, and northern RI. Less humid. Highs 80-87. Wind light NW to N with coastal sea breezes developing.
TONIGHT: Mostly clear. Patchy fog interior low elevations. Lows 58-65. Wind light variable.
FRIDAY: Mostly sunny. Highs 78-85, coolest along the shore. Wind light variable with sea breezes.

DAYS 6-10 (AUGUST 6-10)
A broad trough will move across the region August 6-8 with a risk of a few episodes of showers and thunderstorms, a brief spike of heat possible then a cooling trend. High pressure builds in with fair weather by August 9-10.

DAYS 11-15 (AUGUST 11-15)
The upper pattern will feature high pressure ridging further west in the US and well off the Atlantic Coast which will allow the jet stream to sink a little further south, preventing major heat and bringing occasional shower and thunderstorm threats for mid August.

  5. Climbed Mt Pierce yesterday. Trip up was great. Scenery at the top is beautiful.

    Trip down got caught in pouring rain, thunder and lightning. Got lost on trail. Had to backtrack. Found trail again but the trail is rocky, slippery, muddy and it was getting dark. Ended up slipping and falling several times including into a creek where my pack went into the water. Rocks were like ice. Finally made it. Took over 4.5 hours to get down. Couldn’t call anyone because cell phone got wet. Long drive home.

    Good example of what can happen when you think you can beat the weather!

    2. Now that’s a hike you will never forget!! Recipe for a twisted ankle. Were you solo? Glad you did make it out ok!

    4. So glad you are ok but what a scary adventure. Were other hikers meeting with the same problem on the descent?

  7. Thank you, TK! Sorry – I was busy commenting earlier and neglected to thank you for all you do!!!

  9. Somehow, it would be nice if the landbreeze could hold at the coast all day, however, the wind flow seems to light.

    The dewpoint at the Boston harbor buoy is 69.8F, so while the air temp will be held in check, it’s likely dewpoints climb back up some along the immediate coast this afternoon with the seabreeze.

  10. Friend in York said he was in path of the microburst that hit that area. 50 or so trees lost at the golf course alone.

    Driving through Sutton this am, it was easy to see that the storm was stronger north of me. Branches and some downed trees littered the road and sides of road. Certainly nothing like north of here.

      1. It is a beautiful area. And also a nice place to retire. I think Mac and I would have taken a hard look. Shopping, restaurants, play houses, beaches…

        They sure did get hit. I believe that was the cell that TK said was the only supercell in yesterday’s mix.

    In the mid-lower left of this image, hopefully you can find the northern Siberian coast of Russia. Amazingly, from the coastline, out to now 80 degrees north latitude !! is a large area of open ocean with no sea ice.

    At the bottom of the photo is the northern Alaska coastline. Because a large storm is there, it may give the appearance of ice, but most of that is clouds and if it were clear, you’d see another large area of open ocean out to about 76 degrees latitude. Currently, sea ice is at its lowest level for the date since tracking began.

    That storm, affecting northern Alaska. Well, it’s not quite a light rain producer north of the arctic circle. It’s got a ton of moisture !

    Per the Barrow obs above, Barrow received 0.38 inches of rain in 1 hour !! and 0.50 inches in the last 12 hrs. They average 1.08 inches for the entire month of August.

  13. Question. My friend in York had said they had a microburst. Does anyone know if the NWS is investigating to see if it was that or perhaps a tornado? He was just telling me about the damage and it is extensive – scary extensive.

    Also, my son in law said driving through Natick this am that a good portion of a corn field had the tops of all of the stalks bent parallel to the ground.

  14. In the lets keep an eye on this. Tweet from Ryan Hanrahan
    Deep Great Lakes trough next week should allow the humidity crank and also introduce the chance for severe weather.

    1. And once that front clears New England, perhaps 2 to 3 days of true summer, polar air. 70s by day, 40s and 50s by night ….. well, that’s what the models are selling 168 to 240 hrs out.

      1. It was the august I remember. Hot of course but also nights when kids were in light Pooh bears.

        Hint. Sears carries toddler blanket sleepers with a small Winnie the Pooh picture on them. They were best quality sleepers there were. My kids called them Pooh bears.

  16. Tom will see if things get interesting middle of next week in terms of thunderstorm development.
