Saturday Forecast

8:39AM

DAYS 1-5 (AUGUST 13-17)…
Your reading assignment was far too long yesterday, so let’s shorten things up today by saying that the overall thought process remains the same: Unsettled weather is the general theme for this period but not a whole lot in the way of widespread rainfall. Still working out some timing issues so the forecast beyond tomorrow is moderate confidence. We’ll be bisected by a front today, as we talked about yesterday, and that will make the weather range widely from northeastern portions of the forecast area to southwestern locations. Still expecting us to get back into the hotter air mass for tomorrow before a front comes back and takes the heat out of the picture for a few days to start the new week. My uncertainty lies in the precipitation chances during the Monday-Wednesday period. Playing the less versus more scenario for now. Updates to come as always.
TODAY: Mostly cloudy southeastern NH through northeastern and east central MA with a risk of a few showers. Elsewhere variably cloudy with scattered showers/thunderstorms, some of which may be strong. Humid. Highs 75-82 coastal NH and eastern MA, 83-92 elsewhere. Wind NE 5-15 MPH over southeastern NH and eastern MA, S to SW 5-15 MPH in areas further west and southwest.
TONIGHT: Mostly cloudy. Patchy fog. Chance of a few showers. Isolated heavier thunderstorms possible central MA to southwestern NH. Humid. Lows 62-72, warmest far west and southwest of Boston. Wind variable up to 10 MPH becoming SE to S in most areas overnight.
SUNDAY: Partly sunny. Isolated to scattered showers and thunderstorms. Humid. Highs 75-80 Nantucket, 80-88 South Coast, 88-95 elsewhere. Wind S to SW 5-15 MPH.
MONDAY: Mostly cloudy. Chance of showers, favoring the morning. Humid. Lows 64-74. Highs 77-85.
TUESDAY: Partly cloudy. Less humid. Lows 60-70, warmest urban areas. Highs 78-86.
WEDNESDAY: Mostly cloudy. Chance of showers. More humid. Lows 60-68. Highs 76-84.

DAYS 6-10 (AUGUST 18-22)…
Speeding timing up with a weak front bringing a risk of showers August 18 then fair weather dominating August 19-21 as high pressure takes over. Warm/muggy and a risk of showers/thunderstorms for August 22.

DAYS 11-15 (AUGUST 23-27)…
Warm to hot, limited shower/storm chances.

        1. Not to make light of it because I was watching g coverage and it is awful ….but is that a brontosaurus in the foreground

  5. I do not know if everyone here knows or not, but the National Park service is thinking of using corporate sponsorship, I do not know about you, but I do not want to see LLD lit signs at the parks. I signed the petition

  6. Good morning and thank you TK.
    Good call on my watering last night. It didn’t rain a drop over night.

    No Eric last night, so I had to settle for Danielle Niles.
    She’s not too bad, infinitely more Superior to Pamela Gardner.
    Anyhow, she called for More showers and thunderstorms today
    and less so tomorrow.

    However, I’m thinking ZILCH for boston until/if we get a wave along the front along about Monday or so.

  7. We may be on the North side of the front. but the dam dew point is still 67
    here.

    Btw, my weather station recorded an even 100 yesterday, while Logan came in
    at 98 and I think Portland,me and Concord, Nh came in at 99.

    I’m thinking it was 97-99 at my house for reasons I have posted a couple of times.

  8. Watching the incredible women’s eight olympics rowing final. USA is heavily favored. Won’t give it away in case anyone doesn’t want to know the result yet.

    1. Having trouble watching ANY of the Olympics this year.
      Perhaps it is due to the disaster that Rio is? I don’t know.

      Every time we put it on to watch the Women’s gymnastics, all that was on
      was swimming. One grow tired of watching swimming.

      1. Disaster aside, I cannot ignore the commitment and sacrifice that those athletes put in, whether they are the tops in their sport or just there, with no chance to win. They deserve respect. I can’t penalize them for IOC corruption and the issues of the host cities.

        1. Certainly agree with that, but IF I am not motivated to watch, I am not motivated to watch. Can’t help that.

  9. Based on movement of radar echoes to our North and looking at the surface map, I
    am wondering if this BDF will actually start moving Northeastward this afternoon????

        1. Lawrence, Haverhill, Billerica, Newbury Wunder all reporting 64ish. Not exactly ahhhh but lower than 71 here

  11. Good morning, everyone, and thanks, TK.

    I have a question for someone in WHW nation:

    The official high temp yesterday at Logan was reported as 98 degrees.
    However, on the link offered by North last night at 9:30 (NWS-NOAA weather conditions at Logan in the discussion on dewpoints),
    http://www.wrh.noaa.gov/mesowest/timeseries.php?wfo=fgz&sid=KBOS&num=72

    the report shows that the temperature was 99 at 2:05, 2:30 and 2:35. Why wasn’t the high temperature officially 99 and not 98? Does the temperature have to stay at a certain degree for a period of time like a sustained wind gust?

    Hot is hot, 98 or 99…Just curious the criteria behind maximum and minimum temperature. Does anyone know?

    Enjoy the weekend, everyone.

    1. Hi Captain.

      This was explained recently, only I can’t exactly remember where it was explained (ON this blog, I believe) or when. I “think” it had something to
      do with rounding on those 5 minute increments on that site.

      I noticed that 99 as well and even posted it here yesterday.

      I’m sure TK and/or SAK would be happy to enlighten us once again.

      1. Thank you. Yup, that was the explanation posted before.
        I just couldn’t remember the specifics. I “think” SAK posted
        that previously.

        Anyway, mystery solved. thank you.

        1. Thank you, everyone. Again, 98 or 99, it was a very hot, uncomfortable day yesterday. I hope everyone who suffers in this type of weather is feeling better real soon.

  12. A couple of points from this morning’s NWS discussion:

    1st, something I find to be HILARIOUS:

    Backdoor cold front will reduce temperatures some across eastern
    Massachusetts

    “some”????????????????????????

    From 98 to 75-80 is only some????????????????????

    GIMMIE A BREAK*()!@&#*!@(#^&*!@^#&*!@#^!&*^!@#&^

    Then, we have TORNADO person (direct from Comic Con?) on duty…

    The presence of the backdoor frontal boundary and low Lifting
    Condensation Levels raises at least a small risk of one or two cells
    obtaining a significant low level spin and possibly a very brief,
    short tornado. This possibility is really quite low, but nonetheless
    these are the type of antecedent conditions we have seen in a few
    past cases.

  14. Are we still suppose to see thunderstorms today for those who live north of the front? I don’t understand how I have a 60 percent chance yet i live north of the front, i thought i would be in the stable air therefore, no thunderstorms

    1. I also remember when the sports segment used to be a handful of minutes and now it seems it’s compacted to 90 sec to 2 minutes. I’d rather shorten the depressing news segments.

    2. Great links, Keith. Thank you.

      To me, Eric ranks at the top of my list of on air weather folks. I love his common sense approach along with his explanations and the time he takes to,share them.

      He is right about the natural reaction of people to turn to TV forecasters when there is a weather event. That is, unless they have WHW.

      It made me smile when he said weather is a conversation starter…I am paraphrasing. It truly is. When conversation lags, it seems universal to turn to weather.

  18. Last 3 runs of HRRR are suspect as they forecast convection that has not verified. The model then uses this incorrect forecast going forward to forecasting showers/storms progressing eastward all the way to eastern MA. I have trouble believing this at this point. Will monitor as the day goes on…

      1. A pyrotechnics company is relying on my forecast today, as are my plans for the evening. 😉

  19. The latest (14z) RAP and HRRR runs both show considerable convection outside of I-95 this afternoon, especially towards northern CT/RI and interior eastern MA, out towards Worcester. They’ve been trending more bullish this morning.

    1. And at almost 16z, the HRRR from 14z had scattered t-storms all over south central NY, nearby PA, and isolated to the east of that. Just a 2 hour forecast that has not verified at all. There is ONE isolated cell in northern PA. RED FLAG.

  21. Marginal risk for severe storms with the exception of eastern areas.
    Tiny slight risk area near Albany, NY

  22. So let’s compare HRRR runs…

    This is the 6-hour forecast for 17z (1PM) from the 11z run: http://www.tropicaltidbits.com/analysis/models/hrrr/2016081311/hrrr_ref_frzn_neus_6.png

    This is the 2-hour forecast for 17z (1PM) from the 15z run: http://www.tropicaltidbits.com/analysis/models/hrrr/2016081315/hrrr_ref_frzn_neus_2.png

    Let’s take a look at a radar in 45 minutes and see which one of these is closer. That will tell a lot about the performance of this model going forward today.

  23. GFS model…

    It is STILL making the error of generating phantom precipitation in certain locations, especially along and just off the coast. This has been going on for several days now. I’m surprised it has not been caught, and I’m even more perplexed thinking what the reason for it might be.

  24. Tk, any chance the HRRR has the right idea, except it starts the convection too early.
    like a while back you were explaining?

    Here’s hoping that is the case. The 15Z run looks light a lit up Christmas tree. 😀
    BUT still fires it too early, as it does not verify either.

    1. I think it almost has the right idea, but immediately it’s wrong if those cells are not at least in the general vicinity and nearly as numerous. They clearly are not. Look what it had for MA for noon. The noon hour is almost done, and where is it? And I highly suspect that radar is not going to show what HRRR showed for 1PM. We’ll know for sure in 10 minutes, but I think the answer is already there… Either that or we’re about to see the most rapidly-developing storms of all time. 😛

          1. 100% PROOF on n0n-verification.
            If only the coverage of convection increases, then
            maybe it had the right idea, just to fast with the
            convection. We shall see.

            With out luck, it is dead wrong and will continue
            to be dead wrong.

          2. Well it’s no surprise something is popping early afternoon in that air mass, but a far cry from what HRRR was trumpeting.

  26. Heavy downpours in Norwich, Vermont. Temperature is 74F last I checked. It’s a sticky 74F. I would not characterize the storms as severe. Nor do I think there will be significant flooding. But, it’s definitely pouring with rivulets everywhere and thunder and lightning (mostly in the distance).

    Gardens look great in this part of New England, as do most lawns actually.

    Interestingly – as as is always the case – there is a bit of foliage in the trees here in east central Vermont. It’s only the occasional leaf or cluster of leaves. Yet, they stand out as lonesome red or orange ones among the dark green leaves.

  28. JPD I’ll see your 78 with an 85.1 and raise your 65 with a 77

    Disclaimer. I don’t play poker so have no idea what I just said 🙂 🙂

  29. Small but powerful severe storm by the bay between MA and RI. Lots of lightning with it as well.

    It formed right on the intersection of the back door front and a sea breeze boundary from the South Coast.

  30. BULLETIN – IMMEDIATE BROADCAST REQUESTED
    SEVERE THUNDERSTORM WARNING
    NATIONAL WEATHER SERVICE TAUNTON MA
    130 PM EDT SAT AUG 13 2016

    THE NATIONAL WEATHER SERVICE IN TAUNTON HAS ISSUED A

    * SEVERE THUNDERSTORM WARNING FOR…
    WESTERN BRISTOL COUNTY IN RHODE ISLAND…
    SOUTHEASTERN KENT COUNTY IN RHODE ISLAND…

    * UNTIL 200 PM EDT

    * AT 130 PM EDT…A SEVERE THUNDERSTORM WAS LOCATED NEAR EAST
    GREENWICH…OR NEAR NORTH KINGSTOWN…MOVING EAST AT 10 MPH.

    HAZARD…60 MPH WIND GUSTS.

    SOURCE…RADAR INDICATED.

    IMPACT…EXPECT DAMAGE TO ROOFS…SIDING…AND TREES.

    * LOCATIONS IMPACTED INCLUDE…
    WARWICK…NORTH KINGSTOWN…BRISTOL…BARRINGTON…
    EAST GREENWICH…WARREN AND PRUDENCE ISLAND.

    PRECAUTIONARY/PREPAREDNESS ACTIONS…

    FOR YOUR PROTECTION MOVE TO AN INTERIOR ROOM ON THE LOWEST FLOOR OF A
    BUILDING.

    TORRENTIAL RAINFALL IS OCCURRING WITH THIS STORM…AND MAY LEAD TO
    FLASH FLOODING. DO NOT DRIVE YOUR VEHICLE THROUGH FLOODED ROADWAYS.

    1. Pretty cool that even though the low clouds start to burn off in parts of eastern mass, not one cumulus cloud starts to build in the cooler air to the east of the front.

      1. Yes. The lower clouds were just due to good air saturation in a very shallow layer a few hundred to a thousand feet or so up. But the overall air is still very stable here on this side of the front. And there is a new push of air coming in off the water that may delay the return of the front by a few hours.

    1. I think the temp will stay fairly steady and the dewpoint will go up overnight. Eventually that front is coming back. Stronger gradient and southwest flow will leave it no choice.

  34. Is this even remotely possible for 3AM tomorrow morning?

    It would be near the warm front, but looks to be after it’s passage

      1. Remotely. But if you look at upcoming runs, they’ll all look different. That’s the thing about the short range guidance.

        1. Frustrating to use. And yes I have noticed that about
          it. I just would like to see that rain, that is all.

  37. Many of the same places that got heavy rain yesterday in RI are getting more today. We’ll see if it spreads north/east at all. Quite a bit of activity north of the MA/NH border as well. We still have our private desert here in eastern MA.

  38. old farmers almanac, 2016/2017 winter forecast is out. Calls for cold and snowy. normal precipitation levels. I do not know about the precipitation cooler could be but way to far out

    2. So basically the same forecast they issue every year. Saves them work anyway! 🙂

  39. The EURO is so remarkably consistent run to run. Very rarely does it change something radically.

    It’s had a signal for a couple runs now and it continues on the 12z of a legitimate cold front with cool, dry air in the long range. 850 temps 8 to 10c. Probably upper 70s by day and suburbs in the 50s at night.

    It’s for day 10 arriving in New England. The past few runs at day 10, it was in the upper Midwest, then the Great Lakes, etc. It arrives there on days 8 and 9 on the current 12z run.

    It will be interesting to see if in coming days, it shows consistency pushing to earlier time periods in its run.

    1. The 12z run at 96 hrs also caught my eye for intensifying low pressure passing through northern New England. 1004 mb I believe, not too shabby for mid summer.

    2. Remember those 1 or 2 shots at cool air from Canada we’ve been chatting about here on the blog for around the 3rd week of August? 🙂

  41. Tom heat index hit 100 at 1pm 98 at 3pm where I am.
    In Hartford 3pm heat index is 112 air temp 97 dew point 77.

    1. I think the back door front made it worst down there because it contributed in some way to calming the ventilating SW flow down. I noticed lighter winds down there overall.

  42. Parts of Windham county that were hit hard by storms yesterday now have severe thunderstorm warning.

  43. The Trump Weather Wall is up just West of rt. 495 and the storms bump
    up against it and DIE, DIE, DIE!!!

  44. Front is pretty much hanging in place for now. The stable air over the east is GREAT NEWS for my outdoor plans tonight up in Rockport MA. 😀

    Forecast working out thankfully…

              2. Keep em coming. Hope you go over
                and inch. Your grass will be in good shape for a few days anyway.

                My grass is looking sick. Holding on, but not looking great.

    2. I don’t know but there’s some county in SW NH that’s getting a ton of rain from that area of storms that keeps back building over them.

  47. 4PM Kennedy airport obs at New York.
    Dew point 82!!!

    3PM it was 84 !!!!!!!!!!!!!!!!!!!!!

    1. Absolutely DISGUSTING dps! I hope that is not ours tomorrow, but I suppose once they go above 70, it probably doesn’t matter any more…UGH!!!!

  48. Northen part of cell/cluster has moved EAST of 495. Hopefully a sign of things to come
    later. 😀

  55. Getting dark to my West. An offshoot of that mess out by Vicki is headed
    this way. I fully expect it to DIE before reaching me, but it is on track to come though
    here IF it maintains.

      1. The corrected HRRR had that. The southern MA stuff’s base convection heads southeast because it’s feeding off the hot air. It’s not going to venture into the marine air without dying.

  56. 76 degrees, 69 degree dew point, 0.76″ rain so far. That’s 2.54″ for the month so far.

    1. Awesome.

      Is your location Sutton, Oxford, Or Northbridge?
      I know it is in there somewhere. 😀

  58. The HRRR is now starting to overdo the nocturnal stuff. SOME of that may happen, but not as widespread as it’s showing.

    The other activity is behaving as expected.

      1. I just got a flashback to WBCN.

        There may be some decent cells around. I don’t expect them everywhere. We’ll have to watch radar later.

  59. Just leaving the Yankees/Rays game in NYC. This has got to be the hottest game I have ever been to. Heat index was 113 at 3pm! Thankfully our seats were in the shade or we would have died.

  60. Those mid-late morning HRRR runs today were worthless. Even after its “correction” this afternoon, totally overdid convection. Well done TK. We’ll see about the nocturnal stuff, but I’m certainly not holding out hope for that either.

    I’ve been tracking the “parallel” HRRR as well, which will become the new operational version on (I think) August 23. Perhaps a shade better than the current version today, but had the same general issues of overdoing convection.

  62. In uxbridge now in warning box. They did not get the rain we did in sutton. Son said whitinsville seemed less too. Amazing how fine the line can be.

  63. Mark that must have been great to watch members of the 96 championship team before the game and Austin and Judge hitting home runs in their first at bats in the majors.
    Red Sox lose tonight Yankees only 2.5 out of that second wild card.
    Was not expecting to see a severe thunderstorm watch for my county until 1am tomorrow after the SPC mesoscale discussion was thinking watch was unlikely.

  65. Where oh where is the HRRR convection coming from?
    Warm front to get active? Where???

    Makes no sense to me.

  66. There was another mesoscale discussion that a watch would be likely after the earlier one that I saw was watch unlikely.
    Surprised with one of the threats they mentioned a tornado or two possible with the watch since the tornado percentage isn’t showing up since its less than 2%

    1. From NWS for our area

      So for tonight, the expectation is that much of the area will be
      quiet with the lack of daytime heating. Can not rule out some
      activity getting into NW MA

      This does NOT support the HRRR which is having a rough day.

  68. Looks more like an Upstate New York northern parts of New England isolated severe weather threat. One cell warned in Hudson River Valley moving east but looks to miss me way to the north.

  69. Greetings from behind Basset’s Island, on the anchor on s/v Slip Away. That’s aka Pocasst, or Red Brook Harbor. Current water temperature is 88.9F! Great swimming earlier. Hoping for a peaceful, if warm and sticky night.

    Is it reasonable to expect the storms to say to the north of here tonight?

  70. Back home. We ended up with 1.21

    Temp is 70.00 and Wunder has DP at 69. Coming over hills on way home it looked like clouds has settled in the valleys.

    They had .55 at daughters house in Uxbridge.

  71. I wonder what some of the rainfall totals will end up being in Vermont and NH …..

    And …. what happens to the temps overnight in eastern sections that were cooler today ?

  72. Nasty looking storm moving east looking into northern parts of Litchfield County in CT and parts of Berkshire county in MA. This storm is warned

    1. I see that. Thanks JJ

      Two warning boxes top to bottom in western Ma. I don’t see any cells in one furthest east and it it not connected to one west of it. Is it in anticipation? Says it expires in 44 min. Or am I reading incorrectly

  73. Impressive storms in central mass. As someone said here earlier eastern mass is in its own desert island. I am actually more amazed than disappointed that boston missed all the action other than few rain drops the past few days. It’s like the snow hole that rhode island had in the winter during some snowstorms. Key word here is some. It seems like we miss everything here

  74. Looks like Wundermaps has changed their map page somewhat for the worse. I can’t seem to find a place to save settings (ie: I don’t want to see a 1000 stations…just the radar and fronts). They have taken away the ability to tweak some of the settings too..like store movement and a few others. UGGHH.

    https://www.wunderground.com/wundermap/

  75. Southern ends of those lines seem to be weakening. Makes sense since that is where they were earlier.

  77. I think these rains/storms might have staying power into eastern sections.

    Because …. Warm front is on the move. Cape cod is back to southerly winds and it’s so warm and tropical just above the shallow surface air. I think the temps might zoom up in eastern sections with this band of showers, much like they do in the heart of winter.

    1. Hmmmm. I tried to appease daughters by saying they’d never make it since they would like to sleep without children jumping into their beds. I’m gonna have some ‘splainin’ to do if we have noise and those bright white flashes………although I’ll be too busy enjoying it to hear them 🙂

          2. They are ….. I think the next 20 minutes will kind of tell whether or not they maintain to eastern Mass as they move from very warm, tropical air to a more marine environment somewhere around the Worcester area.

  78. Rockin and rolling with lots of lightning in Sterling. This next line that is coming in apparently has 60 mph wind gusts.

  79. Got breezy and misty here of all sudden. Also a putrid smell (came with the breeze) and the temp dropped 3 or 4 degrees…weird. Is Stephen King in the neighborhood??

      1. Reminds me of the old Chelsea Creek and Fort Point Channel at low tide 🙂 Except the tide was high about 3 hours ago

      1. I have no clue…very strange though. There are wetlands behind the house…but they are bone dry. I’m wondering if there were fireworks somewhere near by earlier and the smell drifted here?

          1. Nope…all dried up in this area anyway. Guess it could be the Back River which mainly tidal and is about a 3/4 mile to my north.

            1. Yes. Must be right in it because I couldn’t decide whether to look north or south and finally settled for middle of room with all shades open

                1. Thanks North. Getting quiet here. They are headed your way but perhaps weakening. Although I said that before. Cells behind this one seem to be weakening too

  82. Hope that pushes through soon Mark.

    Cells generating just west of Boston.

    The whole radar has been neat to watch, but I’ve found the northern precip shield around the Merrimack Valley and north shore to be most interesting …… It’s like it has been collapsing under its own weight slowly southward while the line translates eastward, but the precip keeps generating.

    1. I would have thought….with my uneducated weather mind…that it would have held to the north since the storms went through here earlier and “robbed energy”. How wrong I was. Lightening literally does not stop

      1. I’m guessing ….. The energy may have been robbed at the surface, but a couple thousand feet above, it’s an endless supply of warm, tropical air.

          1. I’m hoping JpDave sees some measureable rain out of this …. It sure looks like the Boston area is about to get drenched. And there are more cells generating btwn Worcester and Springfield on the west side.

            1. I am keeping my fingers crossed too. This is more thunder and lightening here since we had neither this evening but still have had 0.41 with a total of 1.62 for day so far

    1. That’s a good question. I can see by the observations that it’s torrid down there. They seem to be surviving so far …… Might have to nowcast the radar in about 45 min to an hour and see what intensity that have at that point.

      1. Thanks, Tom. It’s oppressively muggy in Yarmouth. Today felt fairly dry until about 7PM when fog rolled in and the humidity shot through the roof. We shall see… For now the radar looks like it might hold together enough to hit us.

        1. Sorry. Again typing too fast. I meant lost power again

          More rolling in here

          What an amazing light show. Constant

  85. Yes power back and storm is through. Was pretty intense for awhile. Only managed 0.3″ of rain out of that though – but we are closing in on 4″ total rainfall now over the past two weeks. some welcome relief.

  87. Some thunder and lightening here and very heavy rain. Seems like the worst is going to the south of me. I hope. Daughter doesn’t want to go to bed yet since she has two skylights in her room.

  88. Up until now lightening has been lighting up the entire sky. As of now….and on radar…I’m seeing some absolutely amazing cloud to ground lightening bolts to my south. And house is shaking. Why does it look like it has passed on radar?

  90. We had heavy rain, thunder and lightning about 1/2 hour ago. Not much rain now but we just had a big clap of thunder. Looks like there’s some more according to radar to the west of us.

  92. Amazing, we actually got some rain with several claps of thunder. Can still hear some
    now and then.

    0.35 inches so far and we may get a tad more. Not sure on that yet.

    I’ll take it. I’d like an inch or so, but I will happily take that.

    Drove to Dairy Queen in Quincy this evening and ran into some moderate drizzle of all
    things and some fog.

    😀 😀 😀

  94. It’s interesting …..

    At the surface, this line of storms has an outflow boundary ahead of it. Gusty N winds came through Marshfield, are occurring at Plymouth and PTown. So, temporarily at the surface, the storms have pushed the surface front southward again in eastern Mass.

    Meanwhile, at Blue Hill, several hundred feet above, the warm air returns with a wind that is now SW.

  96. Mark…will be a long night

    Lightening just looked like a spider web due east of here. But nothing is close. What am I seeing. ??

    1. They sure are.

      I also wonder if something is about to intensify by Buzzards Bay. Big collision of air masses down there.

  99. Not sure I believe the accuracy of the Lightningmaps.org. I just had some pretty brilliant flashes over the past few minutes to my south. I heard the Thunder within 4 or 5 seconds yet the map showed those hits about 20-25 miles south of me between Route 44 and 495.

      1. I use this one often during my Dx listening (radio) to try to see how far static crashes carry on the Longwave, mediumwave and shortwave bands (quite far actually)…but the map lacks the detail of the lightningmaps.org one. But it’s still better than the Wundermap overlay.

  103. I am wondering if that cluster of storms Nearing Hartf0rd will survive a trip East
    given what Tom has reported about Blue Hill. Also, I am noticing a few cells still
    popping out ahead of the cluster. Even if it survives, boston may be North of it
    OR pehaps catch the Northern edge of it. We shall see OR should I say, I’ll check
    the rain gauge in the AM.

    Have just had some very light rain and it finally tripped the rain gauge for another
    1/100.

    Total now 0.38 inch and hoping for more!

    1. Now more popping out by Springfield. Now it looks as if Boston will
      get more rain IF IF IF IF these hold together for the trip to the coast.
      IF not, then well, all bets are off. 😀

      1. Daughter says I slept through first 10 minutes and the house was shaking. This is worst one yet. Getting us both at same time I see

  106. I’ve been enjoying the overnight show as the stuff passes to my south…

    Classic nocturnal warm advection activity. We haven’t seen much of that recently.

  107. Something to keep in mind: The lightning maps can sometimes appear to miss something but they only register cloud-to-ground strikes. Many times you get impressive in-cloud or cloud-to-cloud lightning and that will not show up on the plot.

  108. Incredible light show here right now too lots of vivid lightning very close strikes pouring buckets out there right now. Not going good I just connect all my radios and antennas but I also just connected the cable and phone lines coming into the house

    1. It’s not letting up a little bit most of the lightning is over the water but still pretty vivid at times my earlier post should have read disconnected all my antennas 🙂

  109. Okay and the last post should have said it is now letting up hate the voice thing on my Samsung
