TalcottWx Posted July 27, 2014 Author Share Posted July 27, 2014 Lots of distant thunder emanating from the cell moving toward Marlborough. This day is starting to remind me of June, '87. I've told this story a dozen times ... to paraphrase, we warm-sector-wedged around 1:30pm with the boundary lifting to SE NH, and the region soared into the 80s with DPs rising to 72 after a morning in the mid 60s with thunder and rains ... elevated convection along the displacing warm boundary. Toward evening, a small cluster of cells developed over the Mohawk Trail and roared ESE down Rt 2 during the evening hours. One of the most spectacular severe events of my life outside of a tornado transpired. It came through in two distinct pulses: the first was drive gust front up underneath an atypical shelf cloud. That pulse of wind, which gusted well over 50mph, went calm, and there was this really fascinating 10 minute interval of super bright, multi-pulse anvil to earth CG bolts with bone rattling loud thunder explosions. Then the west horizon started pulsing blinks, overlapping, pretty close to continuous ... as it neared a distant roar began to overtake the near constant roll of distant thunder and then the 2nd wave hit like a p-wave off a bomb blast. Trees just bent in half and hail up to golf ball sized and blinding rain was interceded with strobe lightning... When it was over ... immense timbre damage and power outages all over town. Couldn't hurt to look up stream where there may be some residual SRH later on Funny how our big severe days tend to feature morning mcs or elevated convection, often featuring frequent lightning.

TalcottWx Posted July 27, 2014 Author Share Posted July 27, 2014 Some signs of weakening now, probably stability from the rain earlier taking its toll Link to comment Share on other sites More sharing options...
Typhoon Tip Posted July 27, 2014 Share Posted July 27, 2014 Sharp edge to that convection, bits of sun and blue in NW Middlesex right now. Confirmed in Ayer; sun out... West primarily scudded with saturated boundary layer under lots of blue, and there are distant TCU. My morning pessimism may be overstated... I really have no horses in this race, I just wanted a chance to film TCU maturation. Looks like I may get my chance if things hold. Heading out for a hair cut soon...will assess and set up right after it conditions warrant. Link to comment Share on other sites More sharing options...
Tornadomachine Posted July 27, 2014 Share Posted July 27, 2014 HRRR says its ovah, better luck tomorrowDoes the hrrr clear out the cloud bank? I wish we had a special sounding from ALB, I'd love to see if the new airmass is at all conducive. Link to comment Share on other sites More sharing options...

TalcottWx Posted July 27, 2014 Author Share Posted July 27, 2014 Very evident couplet. If that continues, we're liable to see a wx. id probably say severe but not enough for a tor warn just from the radar.getting dark here. Gusting every 15 seconds to about 30mph. We probably got to 45-50 earlier down the beach. Rain was blowing up the street this am. Link to comment Share on other sites More sharing options...
Ginx snewx Posted July 27, 2014 Share Posted July 27, 2014 Lets see what happens, this sig always interests me in days of higher risk, seems a precursor to have these gravity wave clouds, maybe this is the spot to watch ??looks like best storms of the day were here Link to comment Share on other sites More sharing options...
