I hear ya. But at least it was an already highly anomalous soupy airmass. There were some coastal 80s along the seaboard. Not saying that explains it or that JFK was correct, but at least we’re not talking low 80s vs 65-70 dews.

That's good you brought up the DP plot for the day.  That 81 on the NJ coast... I think that's KBLM?  That's an AWOS so that is likely very suspect.

Damn, I was at Plymouth Lake when this happened.  Just missed it.

By a matter of only a few miles...

BLM and DOV were ASOS…AO2

ESN was manned in the evening

BLM did have TS without precip

NWS was showing (whether or not it gets expanded) most of New England not even in a level 1 for severe; most was confined to SW CT. 

Wow, CT today sure over-performed.  3 discrete cells (one a supecell) lined up across the state, and then a honkin' SQLN sweeps through!  So who on this forum in CT got 4 separate thunderstorms today?  WxWiz????

DOV is indeed an ASOS (DoD run).  BLM is a Federal AWOS,  AO2 shows up both on ASOS and AWOS.  Most AWOS are privately-owned, but that does not seem to change the equipment/sensor issues whether is Federal or private.

One way you can tell a non-Federal from Federal AWOS or ASOS is the SLP group.  if it is missing, that's a non-Federal AWOS.

About 10 years ago. all Federal AWOS got upgraded so they basically report just like ASOS. 

First Federal AWOS were installed in 1989 (KILE, KPWT, and KFOD were the first I think).

I attached a list of all Federal AWOS.

Man times flies. I know most AWOS’s were upgraded to 3PT for precip ID and temp remarks (LCI and EEN got it up here), but I thought it was more recent than that. But now that you mention it I do remember the old 20 minute obs that used to come out of there with the original AWOS.

BTW, whatever happened with the 25k ceilometer rollout? I thought that was happening 10-15 yrs ago and instead only some of the manned sites report/augment it in.

There’s nothing more stupid in weather reporting than reporting an overcast layer at 13kft as “CLR”

I seem to recall a few sites got the ceilometer upgrade going back several years, but I haven't heard much since.  AWOS-4 does not mention it has this upgrade.

Steady light to moderate rain in Falmouth the past half hour.  Can definitely use it down here.

Someone is getting destroyed by flash flooding.  It won’t be that widespread, but that signal means damage.

Spread out over two days may help, but this increasingly looks like it has high end potential somewhere.

Good wind crossing the Sound.

This is close to the radar site, so the radar sample is low elevation.  That wind is likely legit for those in its path.

I saw many, many firework displays off of Falmouth Heights/Bristol etc. beach in the 1980's and 1990's.  I bet tonight was a natural doozy though    'Grats

There almost needs to be a separate scale for the Northeast. The impacts are not equal to other regions. Sure other regions get the higher end severe and more significant, however, a you can get a squall line rip through the Northeast and result in >50,000 power outages and put that line of same strength through the mid-west and barely get 20,000 power outages. Lots of reasons for that obviously but impacts here can be greater just because of population density and trees and how the power grid is configured 

This falls along the lines of how TCs are treated N of 35N.  You can't apply conventional TC rules at higher latitudes due to ET transition and a host of other factors.

I think this was w/ Earl in 2010.  All models had the hurricane passing E Cape Cod w/ its recurvature.  Yet they had TS warning as far W as BDR?  That is ridiculous.  That explicitly says TS sustained (not gusts) are forecast.  How are you going to do that w/ a system that passes E of Cape Cod?  TCs are no longer symmetrical at this latitude due to ET transition, and due to forward acceleration, the winds are greatly mitigated W of the center track.

It's not "one size fits all" for wx events and all locations, but that's the impression I get at times.

Torrington . Scud ??

Yes most likely, and topography often helps w/ the lift, makes the inflow part condense closer to the ground.

Wx tidbit: SCUD stands for "scattered clouds under deck."  I think there is a slightly different definition as well (one word different).   I know some here already knew this acronym, but many mets I have talked to over time had no idea it was an acronym!

That was a pretty wild storm. Wind seemed to switch around to all directions from one moment to the next. Patio furniture survived, but fence is crushed and I think my canoe/kayak are too.

this was a throwback way to end a heatwave. Reminds me of July ‘95. 

Sharp reflectivity gradient on the leading edge --classic sign of strong straight-line winds!

Anywhere near the May 15, 2018 level?  How would you rate?

[OrangeCTWX]

Hope I’m wrong but I’m getting some shades of August 2024 around this area with those rainfall totals, where the Naugatuck valley area got decimated with 10+ inches rain. 
 

As for tonight, I had to drive from Shelton to Beacon Falls right in the middle of it. Rain was insane and lots of cloud to cloud lighting but I think we missed the winds. Clearly some places didn’t though, lots of outages in CT all things considered.

Yes, a 48 hr event will lessen overall impact. 6" of rain in 6 hr is not the same as 6" in 48 hr, at least not for flash flooding.  For larger-scale river flooding, this is not the case.  However antecedent conditions being so dry and water levels low, this should mitigate large-scale river flooding.  Not that there will be none, but "it could be much worse!"  Cliche I know, but sometimes it does fit a scenario well when trying to quantify impact.

I always go back to VT w/ Floyd from 1999 and Irene from 2011.  Similar big rains in VT from both, but Floyd flooding was not big time, but Irene was.  Why?, antecedent conditions.  Summer of 1999 was one of the driest on record for NNE, and summer of 2011 one of the wettest.  Or going way back, Connie and Diane 1-2 punch in a week Aug 1955.  Connie "primed" things, and Diane sealed it.  Worst flooding in SNE on record I think.
