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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Forecasting a record is usually not a good idea. 101 at BDL? That's happened less than a dozen times in the 115 year history of the station. If you forecast 101 at BDL you are saying I think this will be one of the hottest days ever at a station whose all-time high is 103. There's a reason 100 is hard to reach around here. As a forecaster, you'd be better off just throwing up a 97 or 98 on days like these and taking your chances considering how hard it is to verify triple digits. When EWR was struggling I knew it was over LOL.

Most appear to have been replaced in the 2005-07 time frame, but they started as early as 2003 according to this schedule: https://www.weather.gov/media/asos/ASOS Implementation/IFW_stat.pdf

Why can't we trust wind obs? Cups and vanes were replaced by ultrasonic sensors 10-15 years ago.

It's not just summer. Cold winter nights for example are on the decline, and our first frost/freeze dates are pushing deeper and deeper into the fall.
