This is the most notable frame that we observed so far, about 20 minutes ago

Yeah, it is rotating, 

We're seeing a little bit aloft, but not on the lower scans at present

looks interesting that storm west of holyoke

Yeah definitely took on a more ominous look in Southampton, approaching Easthampton.  Brief velocity spike, but magnitudes have come back down.

Early season was pretty incredible last year. Friend's and I skinned Magic on November 21st after about 14". Since my wife and I are expecting this month and will have less time for skiing I'm sure it will be a historically snowy winter. Heck, there are trees in the Holyoke Range already changing color. You're all welcome.

Yep I was there the 23rd making powder turns on Goniff.... And that was before the 30" that fell a few days later.   Best start to the season ever, an all timer in the books in met fall.

The first day of met winter wasn't shabby either

Yeah, it's been warm for sure but I think maybe the dry factor has kept me from being bothered as much by it.  Lot's of upper 80's but not too many 90's here.

There was a substantial latitudinal gradient on the hot weekend for sure.  I was in Keene barely at 90 when BDL hit 100.  Even my torchy station at UMass only briefly touched 95 which has not been terribly uncommon in its lifetime.

I guess S of the Pike has had the torch this year.  Honestly, it has felt like a warm, dry, slightly above normal summer here.  Perhaps the lack of humidity has me unimpressed?  I am pretty mank sensitive and really have not had too use the A/C that much.  Electric bill running way short of last summer.

Fwiw the Amherst coop had July as the 7th hottest on record going back to 1893.  1.7 degrees off the record from 1955.

Hail to 3/4" reported in Amherst/Btown per skywarn

SVR issued for 60mph gusts and penny sized hail.  Seems very legit with definite storm scale rotation and a strong dual pol sig, especially over N Hadley 

Pretty good structure on this puppy, just nw of the UMass radar

Thanks Jay great post.

A lot of these microbursts are really just multicell collapses, particularly with steeper low level lapse rates in place.  I don't think they are especially tied to enhanced shear areas that weak boundaries might provide.  The low level shear algs are actually focusing quite often on the diverging winds near the surface as the descending column hits the ground.   Also, they are pretty hard to anticipate the location based on storm structure alone, unlike with some other types of wind events, gust fronts, bowing segments, etc., and require a beam close to the ground because the sig doesn't extend up too high.

Was just going to post that as well. Wonder if any planes went into it while landing. There have been many terrible large casualty accidents with planes landing and encountering microburst's.

Though I think now they must have some sophisticated technology to avoid it. Like onboard radar or something. 

The TDWR program started after a downburst took down a plane at DFW airport 8/2/85 killing 125 people.  The narrow beam they have was chosen to sense localized azimuthal shear.  But the planes themselves do not have on board weather radar.

Would be nice to have a TDWR (or similar) at BDL.

Toss this.

 

Good stuff there

Maybe some potential for small hail in Chicopee in the cell that exhibited some weak storm scale rotation, but otherwise have not seen a lot to be excited about... Heavy rains here at UMass ongoing at any rate, and some thunder.

edit... gusted to 24mph

Is there anyone here that uses python or familiar with it? I downloaded EDM and basically trying to figure out getting the numpy, pandas, and matplotlib packages. 

From what I'm doing is using command prompt typing in the following line:

edm install ipython numpy

then it compiled and a whole bunch of stuff happened.

I thought all you should do is go into python and type in 

import numpy as np

import pandas as pd

import matplotlib as plt

but when I do I get some error 

Not sure if you figured this out, but in general, post the error

New England beaches are absolutely world class.  We've been stacking 10/10 days, great surf, perfect water temps... Folks of all ages looking like Cheshire cats.   Sharks be damned, we play.

Rough ride on the MVY ferry

CEF was 94 when BDL was 100.  Decent sized spread for those two similar sites.  Now 95.

Media articles citing "at least 1 dead in heat wave" referring to the former OL that passed of heatstroke... While terribly unfortunate worth pointing out that LZK was 0 for the high and +1 for the low.

Cloud deck breaking up here in N ORH county. 

Holy deer flies on the walk. Zapped at least 20

We were up in Petersham last evening and the deerflies were abominable.  Not nearly as bad on this side of the reservoir for whatever reason.

At any rate we're 81, mostly cloudy and a breeze at present.  

Also, the veggies are going off like fireworks.  Get your tomatoes, corn, summeh squashes, chard, kale, red onions, early garlic, new potatoes, blueberries, raspberries, etc, etc.  BLTs simply cannot be beat this time of year.

Screenporch, fan, fireflies, and Perfect Storms tonight.  Caught a nice outflow breeze from a cell just to my north.  For my money last July 1 was way worse... Today felt quite pleasant on the whole.

All of the annual ones have it. The first 3 were JJA. Goes to show the dews are trending worse during the cold season than even the summer.

The BOS one not so much.  But unless something catastrophically changed after 97/98, that argues to me more of a sinusoidal like periodic function, indicating we might be poised for a drop here... granted with higher base due to creeping AGW influences.

And the annual ones are even worse.

That stepwise jump after the 97/98 super nino looks a bit suspect on this one.

 Yeah I saw that coming up 91 towards Greenfield but nowhere to stop for a picture.  some very droopy dark clouds though.

Looked fairly ominous.  Strong on radar but no sign of severe... Very little thunder and we caught maybe a brief 25-30 mph outflow gust out of the north.

View out the office window @ UMass

Not terrible for these parts
