That 94 probably isn't gonna happen. It's only happened that late in the season twice (9/22/1970, 9/20/1983) at BDL, has never happened at PVD, BDR, and ORH, although BOS has six occurrences (1881, 1895, 1914, and 1983).

Highs at the house here the last 3 days have been 70, 67 and 71.  69 currently, The weather feels great but its too early for fall - seasons in seasons.

These departures are the same as if it hit 90 which no one would think is unusual. If a high of 90 would be considered "seasons in seasons," then why not a day where the departure is -10 instead of +10?

Feels like a late September day with temps begrudgingly trying to get into the 70s under a dim sun.

CL&P ftl. Eversource wouldn’t allow the same storm to be as damaging. It will take more in the years to come just to balance out the infrastructure improvements.

CL&P and Eversource are effectively the same company. It's why you can still pay CL&P.

Any word from Twitterverse about Fakersville?  

If I got to 43° perhaps they made it to the 20s?

Colebrook made the low-40s, so I would think Bakersville touched the 30s. Not sure if they had their first frost or freeze, but maybe 38 or 39 there?

Probably some 40s in the hills and the usual cool spots inland. Bakersville probably gets their first freeze.

Looks hot unfortunately 

 

That's a probability map, not a departure map. It indicates direction, not magnitude. If that period comes in at +0.1 or +10.1 it's equally correct. Even a +3 this late in the season is highs around 80 lows in the upper-50s generally across SNE.

They should just use X.5 in the F6 and CLI forms.

I could understand sticking with sig figs and not wanting to create decimals or fractions when averaging 2 integers, but they contradict that line of thinking at the end of the month when determining the monthly average temperature. They sum the max and min integer temps, take an average, and then divide by the # of days and end up with precision down to the tenths place. If you're going to lie there, at least lie to me in the dailies for the F6 and CLI too. Then  yesterday we could've had a mean of 68.5F with a normal of 69.5F and a -1F on the day to talk about on the news.

Or just use tenths of degrees for everything like the rest of the world. Enviro Canada even uses tenths for visibility and degree days.

Sounds like bees are stupid. Wonder if wasps are any smarter.

35 so not that long but enough to provide some comparison.

Damn and I thought I was doing well with 16 years. I guess technically I have enough to establish record highs and lows, since I think you need a minimum of 15 years for that.

Still 2.5 months until first frosts and the leaves change color, at least in Connecticut.

There was a night or 2 maybe 10 years back in early July (the 7th or 9th maybe?), maybe a little more or a little less, that had some amazing radiational cooling setup for SNE, especially SE MA where the temps dropped in the lower 40's. Unheard of for that time of the year.

Anybody know or remember what year that was and have any graphics relating to it?

You might be thinking of 2007. Couple of pretty cool nights right down to the shore right before the 4th. I had back to back upper 40s during that stretch, but that was back when you could get a night or two in the 40s in July and August even along the I-95 corridor just away from the water. Places like MVY and TAN radiate well, so lots of examples of 40s in the summer there.

Looks like BDL also set its record for most 90+ days in July with 18 counting today. Old record was 17 set way back in 2016.

The ASOS dewpoint and temperature readings are extremely accurate. Heck, even the Davis sensor specs are high end now. People generally have more error from the siting and shielding than the instrumentation itself.

 

The one problem the Sensirion sensors have had is that they tend to get "saturated" with high dews sometimes after a swampazz stretch and they have trouble reaching spec again in lower RH situations. I think the newer SHT85s (not Davis compatible) are better suited for meteorological applications. Maybe Davis will switch over from Sensibus to I2C finally ones of these days.

I suspect it's contamination, some suggest humidity sensors should only be passively ventilated to reduce this problem. Most, if not all, high end sensors use a combination of warming and/or a daily purge to stay in spec at higher humidity levels.

I do think instrumentation is a factor in the higher temp and dew point readings.

In what way? I would suspect siting and location changes before the instrumentation. I'm not the biggest fan of using airports as primary climate sites, but they do have weather stations that cost six figures observing 24/7/365, and airports generally don't move like a co-op site might so they've got longevity too. The problem comes when you try to use a particular single site to make your case.

I think the polar jet keeps retreating more north as the arctic thaws. We’re getting to the point where we can’t get a legit cold front in here during the climo peak anymore. 

And the first half of met fall hence the later frosts and freezes. Of the last 20 Septembers, a handful were below normal, and a well below normal month is unheard of now. I guess it's the payback reversal from the late '80s and '90s.

We tied, not ever.  LOL...data comprehension

Ryan updated the graphic for the 5 o'clock news. It now shows 2019 alone in first place at 78.0 which I think he said was the warmest month ever in 114 years of record keeping in the Hartford area.

If we use GON to verify dews, we should use Bakersville for low temps.

The climate division averages would be more representative as it includes first order and co-op stations, so it's a good balance between airport and rural observations.

You can actually just grab the lower right corner of the selected cell (the little square) and drag it down the cells where your totals go. Does it automatically.

Even better: just double click the little square and Excel will auto copy down by detecting the end of contiguous rows.

I'll bet there are lots of (older) buildings in New England without AC. My high school was one of them even though it was built in the '80s. Being just a mile or two from water, when you had a warm late August/early September day, you would just open the windows.

Only about four weeks left for big heat. BDL averages about 1.5 90+ days post-Aug 21, and heat waves after Aug 21 happen about once every 7-8 years on average.

Their highs are quite close to those at NYC - within a fraction of a degree.  Maybe all the trees in Central Park have an effect different from grass plus tarmac.   Of course, NYC minima are probably 5° or more milder than at BDL.

yeah they are pretty close - the peak hi/los this month are:

BDL 84.9/63.1

NYC 84.4/69.2

LGA 85.7/70.1

JFK 83.6/69.0

EWR 86.3/69.1

Technically BDL's average high dropped 0.1 off of the 84.9 peak from the 17th to yesterday. Official tick down doesn't start until tomorrow when the normal daily mean temp drops from 74.0 to 73.9.

1 minute ago, RUNNAWAYICEBERG said:

normal at BDL is really 84? 

Considering this is the warmest week of the year, I would have guessed 85 or 86, maybe even 87. Maybe 84.4 is the monthly average which sounds about right.
