Sustained dews in the 30s and 40s for several periods. That chamber, low dew, shot around the 19th to 22nd...nearing peak climo for the year. Pretty impressive.

And we can barely get sub 50 lows in July now. Link to comment Share on other sites More sharing options...

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.

Typhoon Tip Posted July 30, 2019 Author Share Posted July 30, 2019 Air quality was terrible this morning... Still and stagnant overnight, we've capped civility's farts with unwanted proficiency - In the days of yore ...this would be pure Earth contamination ... bio-mist-related, which I'm sure came with it's own headaches. But this...? it's ( headaches + mankind's putrescence)/2 = some kind of vagarious journey through wafts of various automobile exhaust types, then the ozone faux freshness its self, followed by something that smells like black mold spores... dumpster fires... just eegh Edit, okay ... there is an AQ alert in addition to the heat alert in effect. it's going to be a miserable one boys and girls.

Bostonseminole Posted July 30, 2019 Share Posted July 30, 2019 some really good information in here about Climo, which we can move some of the back and forth about COC definition to banter.. would make this easier to follow. Just saying. Link to comment Share on other sites More sharing options...
dendrite Posted July 30, 2019 Share Posted July 30, 2019 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.

Bostonseminole Posted July 30, 2019 Share Posted July 30, 2019 How come I cannot find historical information on the Hamscom site?, they have daily observations but don't seem to include it in the NRCC? is there another place to find historical for that site?

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. Link to comment Share on other sites More sharing options...
Bostonseminole Posted July 30, 2019 Share Posted July 30, 2019 Wiz, what do you think about tomorrow? SPC: ...Northeast and Mid-Atlantic... Ample diurnal heating will occur ahead of a surface trough extending from the Northeast through the Mid-Atlantic. Convective development will likely occur by early Wednesday afternoon along this surface trough, with weak to moderate instability forecast across the warm sector. Around 20-30 kt of mid-level southwesterly flow associated with the upper trough may be sufficient to loosely organize storms into clusters as they spread eastward through the afternoon and early evening. Although mid-level lapse rates are expected to remain poor, steepening low-level lapse rates combined with the modestly enhanced mid-level flow and high precipitable water values may support strong/gusty downdraft winds capable of producing occasional damage.

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. Link to comment Share on other sites More sharing options...
