July 4th Week Extended Outlook (Update)

249 Comments

2:08AM

With no major changes to the forecast, this is basically a re-issue of the last blog with tweaks for timing and a few added details, and of course updated for the time period.

Here is my best guess at the weather pattern and resultant day-by-day weather through the first week of July.

The battle between a high pressure ridge over the western Atlantic Ocean and low pressure trough centered near the Great Lakes will continue through the first 2 days of July, with a retrograding ridge eventually being the victor. The result will be mild to warm air, high humidity, and episodes of scattered showers and thunderstorms through early Tuesday, though many areas will see lengthy stretches with no rain. The wettest times are most likely to be the early hours of Monday, late Monday night, and very early Tuesday.

High pressure will continue to drift westward over the western  Atlantic and US East Coast through much of next week, only weakening a little as disturbances try to ride over the top of it from the west by the first weekend of July. The overall pattern for this area will become hotter and continued humid. Shower and thunderstorm activity will be isolated to scattered at best.

Updated forecast for southeastern New England (RI, eastern MA, southern NH)…

TODAY: Variably cloudy – sun more dominant morning and first part of afternoon, clouds more dominant later. Only isolated showers and a slight risk of a heavier thunderstorm. Humid. Highs middle 70s to lower 80s, coolest South Coast and Cape Cod. Wind S 5-15 MPH, up to 20 MPH some coastal areas.

TONIGHT: Mostly cloudy. Showers and thunderstorms increasing from the west and south. Some downpours. Humid. Lows in the middle to upper 60s. Wind S 5-15 MPH.

MONDAY: Mostly cloudy. Scattered to numerous showers/thunderstorms in the morning, less numerous in the afternoon, may increase again at night. Highs 75-80, cooler some south-facing coastal areas. Wind S 10-20 MPH.

TUESDAY: Partly sunny. Lingering showers/storms possible early in the day. Isolated storms may develop again later in the day. Low 67. High 83.

WEDNESDAY: Partly cloudy. Isolated late-day thunderstorms. Low 68. High 84.

THURSDAY: Partly cloudy. Isolated late-day thunderstorms. Low 68. High 86.

FRIDAY: Partly cloudy. Isolated late-day thunderstorms. Low 69. High 88.

SATURDAY: Partly cloudy. Isolated showers/thunderstorms. Low 70. High 90.

SUNDAY: Partly sunny. Scattered showers/thunderstorms. Low 70. High 88.

  2. Tk, what about nights say 9 pm or after for the 4th? Rain, yes or no? We ahve to watch our fireworks.

    1. I watch that situation very closely. I probably go to more fireworks displays in May through August than everyone else here, combined. 😉

      Are you targeting certain nights?

  3. Today’s AccuWeather Trivia Quiz.

    Which term describes air moving from one location to another?
    A. Conduction
    B. Advection
    C. Convection
    D. Radiation

    Answer later today. I expect everyone to get this right.

  5. Does anyone know how to get rid of poison ivy? We sprayed but it doesn’t seem to be doing anything and we discovered we have a ton in one area

    2. Vicki,

      My father in law used to work for the town and they used the Round Up spray. Supposed to work really well. Don’t burn it….

      2. Thanks Scott. We will try roundup. And my brother burned it once and it was a mess. Thanks for the warning.

        1. Hi Vicki,

          This is Mrs. North (Sara) and I am an expert at poison ivy removal! The only way to get rid of it for good is to rip out the vines and all the roots. I had to do this at our last house and it never came back. We tried round up, but that just kills the weeds temporarily. Good luck!

          1. Hi Sara its nice to meet you and thank you so much for your help. Did you do this in winter when there were not so many leaves? I afraid whoever does it now will get a bad case of it. Or should we hire someone?

            I just discovered mac did use roundup but nothing has changed. He just sprayed it a second time.

            Thank you very much!!!!

            1. No, I did it in August so I could see it all. I was in long pants and a long sleeved shirt and was very careful! Be careful when sawing the vines off the tree trunks because the dust flies!

              1. Thanks Sara. Mac will have to do it. I have always had an extreme allergy. Ill suit him up though.

                I promise to let you know how it goes. 🙂

  6. Another day of not-much-rain in this “rainy” pattern the NWS has been dooming and glooming us with. Again I don’t like to slam, but whoever came up with the format for those forecasts that probably unintentionally make it sound like it’s going to rain all the time needs to revisit that thinking.

    How many people cancelled outdoor plans because they looked at an icon that said “heavy rain” for today when in fact the actual forecast should be for isolated showers/storms that may produce passing downpours with most areas remaining dry most of if not all of the day? Maybe it’s a limitation of budgets, but it’s a shame. No added value to what is most easily accessed. Something is wrong here. 😛

    Ok editorial over!

    1. TK I was groaning about the same thing yesterday. The funny thing is even after we have the days where its obvious rain played a far smaller part than people thought it would, you’ll still hear comments that this weather is awful.

    3. Well said. I was worried about the heavy rain here while we were in Maine. There was .37 while I was gone for 4 days! Maine was beautiful when we left today. Figures on the last day, although yesterday wasn’t too bad!

  8. Pretty mundane day today.

    I’m going out a limb 😀 and say Boston doesn’t see a drop of rain today, which would
    pretty much make 3 days in a row. 😀

    1. Works for me. After organizing in-house this morning I shift outside this afternoon for a short clean up followed by a water fight and then a bbq. 🙂

      1. Indoor High School Graduation Party for a neighbor.
        Too humid to be stuck indoors and this location does NOT
        have AC. 😀

    1. OS if im seeing this correctly, my daughter showed me the same type of thing along the New Jersey coast on the radar the other day

    1. Quite a bit of filtered sun probably. Some of those clouds are struggling to maintain their integrity as they slide up over us. But that lack of full sun is also limiting storm development. Main support is offshore and well to the NW. Left in the middle here, which again is FINE with me today.

      1. Filtered, eh? I guess it depends on timing and location.
        Let’s say it is WELL filtered here at the moment. 😀
        But yes, there is a bit of sunshine filtering through the clouds.

        Probably Rain free pretty decent day. I suppose something
        could bubble up, but I doubt it.

        1. You are both right – there are areas of heavier cloudcover. Still filtered sun here in Woburn – dimmed at times. Satellite trends show the heaviest cloudcover probably stays hugged to the South Coast and South Shore for a few hours. We’ll be at least partly sunny back NW of Boston.

            1. Here too… filtered but it has been out so to speak for the past hour or so here in Hingham

    1. Exactly where expected. Note the northern edge of the rain approaching the South Coast is eroding.

    2. The point where the best lift is focused, usually at mid levels. It’s a little different from a surface boundary by being located a few to several thousand feet up.

      1. Thank you and understood, however, Not obvious on any maps
        I view at surface, 850mb, 700mb and 500mb.
        Is it at a different level?

  15. Rain to the South really broke apart, however, storms to the West have
    become more numerous. 😀

  16. Regarding yesterday’s trivia quiz answer of D (all of the above), how does dust & pollen contribute to fog/mist development?

    I would appreciate an explanation from TK or anyone else…Thanks in advance. 🙂

    1. I didn’t know that dust and pollen contribute to fog mist development. You learn something everyday.
      Feeling like south Florida and waiting to see if any downpours develop.

      1. I suppose it facilitates droplet formation, BUT still need the
        other condition of Temperature equal to dew point, so in my opinion it should NOT be included. 😀

      2. JJ, sure looks like you are getting your downpour or else you are
        awfully close to it. 😀

    2. The droplets for everything from clouds to the heaviest precipitation still need something to condense onto. All of the above. 🙂

      1. That’s a given. Still think it should NOT have been part of the answer. That would lead one to believe you could have Fog WITHOUT the other conditions. Just not so. 😀 Just how I see it.

      1. He’s at a 14 hole course a few miles from our house. The radar looks to be sliding everything well west of here but I think he has cell service. Thanks OS

  20. Coverage, even to the west, is still quite low. Remember, NWS radars always make coverage look greater because their regional loop really overdoes blow-off and elevated convection. The vast majority of the area will remain rain-free through the early evening hours.

  21. I am quite happy that the weather cooperated for our first annual Pan Mass Challenge Kids ride in Plymouth today. I worked very had with my neighbor to get this organized and we raised over $7000! The cloud cover was quite welcome and we were thankful for no rain. Now let’s hope we don’t melt at the 4th of July parade! Hope everyone had a good weekend.

  22. Answer to today’s AccuWeather Trivia Quiz.

    Which term describes air moving from one location to another?
    A. Conduction
    B. Advection
    C. Convection
    D. Radiation

    The correct answer is B. Congrats to all! We got a 100%.

    1. Mugar was a great friend of my family. Nice guy. National doesn’t bother me in the least as long as we see it here. Its our celebration after all

        1. I read quickly. I thought it said locally but not nationally. Its always been local until – what 10:00 or 9:00 – then goes national.

          1. Dallas next year will start having there fireworks national televised in replace, again we all know what I’m gonna say but I will respect the blog but extremely angry and sad 🙁
            Cloudy and drizzly down here

  25. Good morning all,

    Hmmm NWS has a flash flood watch up.
    We’ll see.

    Right now, still looks like our area is nestled between 2 rain areas.

    Time will tell. 😀

  26. One area where the rain is heavy is across Hudson River Valley and Northern NJ with multiple flash flood warnings. In fact parts of Northern NJ had a tornado warning earlier. Thankfully the warning has been dropped as that cell is moving northeast toward where I am in CT.

        1. It has, which is surprising to me given that features are retrograding, I figured the stuff to our southeast would be edging westward.

          With that said, the stuff in SE Mass is moving from SW to NE, the stuff out in NY State is moving from SSE to NNW, so, there’s definitely an area in eastern NY State and far western New England where the air is spreading out aloft, causing a lot of lift through the column and thus, all that heavy rain. That region seems to be getting clobbered at the moment.

  27. Getting clipped by the northwest fringe of that rain area in SE Mass.

    Awful story about the 19 firefighters lost in Arizona.

    1. Tom such a tragedy…19 elite firefighters. And the heat in the area will only fuel more fires.

      1. My wife and I couldn’t believe it when we saw that on the news last night. They must have been trapped somehow with
        a wind shift or some other UNEXPECTED event. A real
        Tragedy.

        1. TWC this morning had the obs from that town yesterday, and while the winds were not vicious, at one point, they did switch from southerly to northerly. They said that this did not verify any explanation, but that the wind shift did occur.

          1. That wind shift could certainly cause a major problem for the fire fighters and “may” explain what happened. I’m sure we’ll hear at some point.

  29. The June numbers are in at Logan ….

    Temp : +1.9F. Precip : +6.82 inches

    Third month in a row of above normal temps. Within these 3 months, the departure has been increasing with each passing month … Apr : +.8F, May : +1.0F, June : +1.9F.

    I think July will continue this trend, with temps +2F or higher above normal. 2 reasons : the forecast for the first 7 to 10 days of July and the persistent pattern this summer seems to be the Bermuda High for the eastern US.

    Data from Taunton NWS climate section.

    1. Thanks Tom.

      Interesting with 3 consecutive months of above average temperatures, the ocean temperatures do NOT appear to be above average. They are “about” average in most places and even a bit below in other places. Oh well.

  30. There seems to be other areas popping up in between the main 2 areas.

    http://www.wunderground.com/radar/radblast.asp?zoommode=pan&prevzoom=zoom&num=10&frame=0&delay=15&scale=1.000&noclutter=0&ID=BOX&type=N0R&showstorms=0&lat=0&lon=0&label=you&map.x=400&map.y=240&scale=1.000&centerx=400&centery=240&showlabels=1&rainsnow=0&lightning=1&lerror=20&num_stns_min=2&num_stns_max=9999&avg_off=9999&smooth=0

    I wonder IF both areas will merge into one huge rain area?

    Still watching it unfold. 😀

  31. So much for not having severe weather today. The cell that was in northern New Jersey that had a tornado warning now prompting a tornado warning in Fairfield County until 11:30 Pm.

    1. Interesting as I don’t see anything remotely resembling severe on
      Nexrad Radar. Nothing. All looks very routine.

  32. The warning was allowed to expire at 11:30. There is no rotation being detected with that storm currently. This storm has been pulsing. It did have a tornado warning with it in Northern NJ. It then weakened and then a severe thunderstorm warning was issued for the NYC area. It weakened then a tornado warning was issued for parts of Fairfield County.
    I don’t think a tornado did touch down but there was just enough rotation for NWS out of Upton, NY to issue the warning and it certainly did not look like the torando that touched down in Springfield when you could see a well defined hook echo.

    1. Remain vigilant. One never knows.

      It concerns me that the SPC has that large area with a 2% chance of
      a tornado. That INCLUDES your area JJ. 2% is very low and the prospects of a tornado is very unlikely, however, the chance is NOT ZERO as confirmed by a storm with rotation already.

  33. Right now its just starting to pour here but the way this storm has been going I wouldn’t be surprised if it strengthens again.
    This is a great example of what a pulse thunderstorm could do where you go from nothing to having a warning then it weakens. With regards to the 2% chance of a tornado I have seen tornadoes happen with that probability in Bridgeport CT back in June 2010.

  35. Storm capable of producing a tornado, according to dopplar radar, just south of Springfield, MA has had a tornado warning on it since about 1:30 pm.

    1. Hmm

      I have NOT seen any of these today, but I’ve been pretty busy at work and my timing probably wasn’t good. Current storm does NOT look tornadic to me. Tops also are fairly low.

      Info on storm:

      1 R4 50 dBZ 21,000 ft. 12 kg/m² 0% chance 0% chance 0.00 in. 19 knots SW (234)

      That means no hail, no chance of hail. Tops only 21,000 feet. High enough,
      but not that high.

        2. I think the weather underground radar is the best !!

          The tornado warning expired and has been replaced with a severe thunderstorm warning on that cell. A severe weather report says that storm brought down trees in Windsor Locks, CT.

          Boy, north Central MA has really filled in with heavy rain. It is even more oppressive today than the last few, I think.

    1. Agreed.

      Just came in from Lunch. Wow, humidity is awful.
      1PM dew point at Logan was 71.1.
      Logan temp was 78 which reflects a SOUTHEAST wind.
      In JP temp was 83-84 and wind more South or SSW.

      1. Try working outside in jeans and boots, I’m soaked. But I’ll take this over winter anyday.

  37. The sun is breaking out – partially and occasionally totally – between rounds. When it is out in full, it is uncomfortably hot.

    1. Temp 77 with a dew point of 76 …………… think snow, think snow, think snow!!

      Oh sorry….was chanting to myself 😉

  38. I believe this is the same storm that started in Northern NJ where a tornado warning was. I said earlier I would not be surprised if this storm strengthened again. It will be interesting with some of the pictures I am seeing right now on the television if a brief tornado touched down in parts of northern CT.

  40. This has been this history with this thunderstorm. It strengthens it weakens and then it strengthens. There have been reports of a funnel clouds near the Windsor Locks area. Of course the NWS out of Taunton will probably be investigating this. I know the NWS is out in Northern NJ investigating damage this afternoon where the first tornado warning came out with this storm.

  41. Another storm with some dopplar indicated rotation in the Merrimack Valley, now has a tornado warning on it.

  42. Now just noticed new tornado warning to the north and west of Boston. This is a doppler radar indicated tornado. This is a different thunderstorm than the one that has been tracked since the middle of this morning.

  44. From NWS:

    2 PM UPDATE…
    WE HAVE RECEIVED A FEW SVR REPORTS OF DAMAGING WIND AND SEEING
    LOW LEVEL ROTATION ON SOME OF THESE STORMS. WHILE MID LEVEL LAPSE RATES ARE POOR AND MLCAPES ONLY AROUND 500 J/KG…WE HAVE SBCAPES 1000-1500 J/KG WHICH IS JUST ENOUGH INSTABILITY COMBINED WITH 30-40 KT EFFECTIVE SHEAR TO SUPPORT A FEW MINI SUPERCELLS. ISOLD SVR THREAT WILL CONTINUE THIS AFTERNOON IN THE INTERIOR.

  45. Old Salty here is the latest statement on that tornado warning which is in effect until 3:15.

    1. Thanks JJ. Had looked there earlier and saw nothing, so I didn’t return.
      Yes, I use that site often.

      BTW, NEW action between main action and the coast.
      Hmmm Interesting. We’ll keep watching.

    2. They should be, that looks most vicious on the radar.

      Vicki, you might be hearing thunder, as a cell is popping pretty quickly just to your northeast.

      1. Thanks Tom. I’m busy warning everyone else and forgot to look for me

        I just got a warning for framingham – tornado. Is that correct?

        1. I dont think Framingham is in the direct line of these 2 storms ….. But, I did notice a heavier shower popping as it was going by Framingham.

  47. New Tornado Warning for that cell near Peabody:

    BULLETIN – EAS ACTIVATION REQUESTED
    TORNADO WARNING

    * UNTIL 345 PM EDT

    * AT 254 PM EDT…DOPPLER RADAR INDICATED A SEVERE THUNDERSTORM
    CAPABLE OF PRODUCING A TORNADO. THIS DANGEROUS STORM WAS LOCATED
    NEAR WENHAM…OR 3 MILES WEST OF BEVERLY…AND WAS MOVING EAST AT

    * LOCATIONS IMPACTED INCLUDE…
    BEVERLY…GLOUCESTER…PEABODY…HAMILTON…WENHAM…DANVERS…
    MIDDLETON…ROCKPORT…IPSWICH…TOPSFIELD…ESSEX AND MANCHESTER.

    PRECAUTIONARY/PREPAREDNESS ACTIONS…

    TAKE COVER NOW! DO NOT WAIT TO SEE THE TORNADO. GO TO A BASEMENT OR
    INTERIOR ROOM ON THE LOWEST FLOOR OF A STURDY BUILDING…AWAY FROM
    WINDOWS. IF IN A VEHICLE…A MOBILE HOME OR OUTDOORS…GET TO THE
    CLOSEST SHELTER. PROTECT YOURSELF FROM FLYING DEBRIS.

  48. It “Appears” that the SPC SHOULD have had the area at MORE RISK.

    Shame on them!

    1. Last week we had multiple days with slight risk for severe weather and other than last Monday when we had a few severe thunderstorm warnings most of the storms were rain producers. Today no risk and there have been multiple tornado warnings
      across SNE. Two in CT and two in MA. If these storms have or are producing tornadoes I would think we would be looking
      at EF 0 EF 1 tornadoes.

      1. JJ Check out the rotation on the one heading towards gloucester.

        I’m betting that one is MORE than an EF1.

    1. Tom,

      THAT is my concern. With high dewpoints, High enough temperatures,
      SE to S wind at surface and Sw wind aloft, “could” spell trouble.

      We need to keep our eyes on the radar!

  50. I’m not seeing any storm on my radar inside 495 or heading here and I just got a pop up warning on my phone for a tornado warning in framingham ……does anyone else see that?

    2. Vicki,
      There is a storm Just to your North. You should be hearing Thunder as
      Tom pointed out.

  52. Hopefully people are taking shelter in that area. We have seen it with these storms today where there is nothing there and all of sudden bam like the one that produced the possible tornando in the Windsor Locks, CT area. We know there were funnel clouds thanks to eyewitness pictures.

  53. Vicki,

    There is another storm popping around Hopkinton, which would head
    exactly in your direction. Keep an eye on it.

  54. 15:12 Update from NWS, funnel cloud spotted:

    http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=box&wwa=tornado%20warning

    …A TORNADO WARNING REMAINS IN EFFECT UNTIL 345 PM EDT FOR CENTRAL
    ESSEX COUNTY…

    AT 258 PM EDT…TRAINED WEATHER SPOTTERS REPORTED A FUNNEL CLOUD
    NEAR DANVERS. A TORNADO MAY DEVELOP AT ANY TIME. THIS DANGEROUS
    STORM WAS LOCATED NEAR ESSEX…OR 5 MILES NORTHEAST OF
    BEVERLY…MOVING NORTHEAST AT 25 MPH.

    LOCATIONS IMPACTED INCLUDE…
    BEVERLY…GLOUCESTER…PEABODY…HAMILTON…WENHAM…DANVERS…
    MIDDLETON…ROCKPORT…IPSWICH…TOPSFIELD…ESSEX AND MANCHESTER.

    1. Now the question is did the funnel touch the ground. If it did that we have a tornado. We have seen in funnel clouds that went
      through the Windsor Locks CT area.
      The atmosphere is sturred up today.

  57. It does make sense that Middlesex County and northeast Mass (Essex County) are getting hit. I would think given today’s weather, it accumulated the highest heat content across the area. It was raining in western New England this morning, as well as southeast Mass, but the above region was dry all day with some sunshine. Its all furthest away from the indirect southerly seabreeze.

      1. Waterspout for anyone here on the blog not familar with the term is a tornado over water. If the water spout comes
        on land and touches down it becomes a tornado.

  61. Quite a cell right at the cloverleaf of Rte 128 and 93.

    And poor Lowell is about to get drenched again.

        1. Good for you seeing system around Woburn before the warning even went up..although doesn’t surprise me as I’ve seen u do it multiple times

        2. Oops I didnt say there was a warning in your area…I said in the area you called earlier….meaning Woburn.

          Although I have now received 3 pop up warnings from the nws for framingham. The latest was just a few minutes ago

      1. Southern part of cell near Lowell. billerica is a concern at the moment.

        The cell northeast of Reading, MA also looks suspicious.

  65. The new tornado warning up until 4:15 pm. Again areas to the the north and west of Boston. I noticed some of the same towns mentioned in this tornado warning that were in the previous tornado warning that headed toward the Glouster area.

  67. New Tornado Warning up at 15:35:

  68. Ch 4 and 5 had some photos of BIG trees uprooted in Agawam, MA…. Which is evidently just southwest of Springfield. That cell earlier in the day was damaging. They also have video showing a funnel cloud out in Windsor Locks, CT from earlier in the day.

        1. The storm just exploded over that part of CT. Thankfully were not hearing reports of any injures or
          fatalities but there is damage and the NWS out of Taunton is going to be busy here in CT and up there
          in MA surveying damage. I am interested in reading their findings when it is released.

  69. All these cells look so much alike, like fingers ….. oriented north to south, thin and absolutely flying.

    1. The one East of Woburn looks absolutely BRUTAL. I wonder if that
      one will produce a warning?

  71. Yikes, storm now approaching Beverley looks like it is about to blow
    a head gasket!!!!!!!!!!!!!!!!

  73. That is a bunch of tornado warnings for our area, not often seen in these parts,
    AND WITHOUT any SPC indication of expected severe weather!!!!!!!!!!!!!!

  76. Sky warm reporting funnel cloud over south Peabody area…no touchdown.

    U mass Lowell had over 2 inches rain so far

  78. There sems to be one final cell further west, maybe sw of Westford, that looks similar to all these cells and may be starting to intensify.

    Not saying next batch of showers will hit the same environment (at surface or aloft), there is an encroaching band of showers in SE Connecticut and the eastern side of the showers look to be slowly intensifying.

  80. Waking up this morning I did not expect a day like this. I expected the heavy rainfall but not tracking thunderstorms capable of producing tornadoes. I agree with the comments made why no mesoscale discussion when there have been multiple tornado warnings today. Last August when we had a tornado warning in southern CT storm prediction center went on to issue a tornado watch for about a 4 hour period that covered eastern parts of SNE.

  81. New cell N&W of Uxbridge towards Northbridge looks to be intensifying. Needs to be watched. Hopefully, it doesn’t get to the point of the others.

      1. Vicki, it appears to be North and West of Uxbridge, more headed
        towards Northbridge. 😀

        AND it is not severe at this point.

        1. I did see that but it seems as if they are popping and I want her to beware and I’m not sure if she’s out and about

  82. It doesn’t stop.

    Brand new STRONG cell just popped up between Woburn and Beverly.
    INSANE!!!

        2. I’m not sure why, perhaps not the traditional supercell thunderstorms and perhaps many rotate, but are not likely to drop anything more than an F0 or a very weak, quick F1 that local tornado warnings or severe thunderstorm warnings wouldnt cover. I’m sure TK will have a good explanation….

          By the way, southwestern RI looks like some cells are developing.

          2. These storms were not much unlike the ones you find in spiral bands of landfalling hurricanes or tropical storms. Low level wind sheer, shallow storm tops, generally relatively very weak tornadoes. Sometimes this condition will develop quickly and is not always caught that far in advance. I didn’t catch it until about 1 hour away from the action.

  84. I have a feeling this is going to be a hot wet summer, hope I’m wrong on the wet part. They say a patern change is coming.

    1. I hear snow is in our future 😉

      So why the outbreaks without any warning? Risky I think but interestingly enough even in places I didnt expect the word got around.

      1. There will be no snow naturally at either of our houses for at least another 20+ weeks 🙂

  85. Pardon my absence a bit today.

    It was one of 3 out of 11 days I’m not day-tripping on my vacation time, but I had a car in the shop, another about out of gas, and a host of errands to do including 2 hospital trips for testing. And of course all heck breaks loose with the weather. 😀

    Blog will be updated a little later this evening!

      1. O.S. you did a wonderful job keeping the readers updated, along with others here! Thanks all. 😀

  87. If I may toot a few horns. Old salty called the last several – if not each – warning before it was posted and Tom special kudos to you as well. Impressive doesn’t say enough!!

    2. Way too kind Vicki! Just describing what we saw on radar is all. 😀

      The weather underground Nexrad radar display is awesome!
      I love being able to see the relative velocities where rotation can
      be picked up. Link if anyone doesn’t have it already:

      1. Tomorrow is NOT supposed to be a repeat, but we’ll be watching
        just the same. 😀

      2. From Matt Noyes:

        Matt Noyes: Broadcast Meteorologist
        Bryan Farr, of Historic US Route 20, grabbed this picture looking from Revere Beach toward Swampscott, MA. At this point, no report of a tornado touchdown or damage in that area, but surely you can see the cause for concern here! In a tropical airmass, cloud bases are low, and what typically would be a funnel aloft can easily become a brief touchdown…hence the tornado warnings we saw today.

        1. More from Matt Noyes:

          Matt Noyes: Broadcast Meteorologist
          Monday afternoon tornado confirmed in Windsor Locks, East Windsor, Connecticut. I fully expect, based upon our NECN storm damage video, Agawam MA will be classified similarly, but we shall see. Initial storm survey details from Connecticut can be found at http://mnoy.es/13mv54T

    3. Thanks Vicki. It was an interesting afternoon just watching and by about 5pm, I was mentally tired ! Anyhow, just thankful to pursue my #1 hobby here on the best weather site around. 🙂

      1. Tom. You two were great and I thank you. I was exhausted also and all I had to do was read – and call/txt people. I can’t begin to imagine how you felt

  89. god darnit … i missed it. i was in Boston while that storm went right over head. 🙁 god darnit work and getting in my way of weather geeking. My mom told me there was alot of rain my guage has 2.7 inches of water in it, my mom said the trees were bending so close that the big oak was going over the pool. People are saying there was a funnel cloudy out at the church at the common. highest point of town. which is not that uncommon actually.

    1. Matt I thought of you. The media was in Billerica for flooding. Glad you are all ok and sorry you missed it. I can appreciate that.

    1. Absolutely incredible photos!! and to think that we could see the tornadic
      signature and rotation on the radar!! Awesome day in New England weather.

  93. The blog is updated. I should be about a little more during the day Tuesday in case any interesting weather gets cranking…
