And oh yeah...looks like the observer has no temp or dewpoint data so they're just submitting it as 0C/0C. I can't wait for July lows of 32F at Naples to go into the climate record. lolol
I noticed APF got fried the other day too after a TSRA. Now they have daytime manned obs and they're putting ASOS OTS at the end of them. I have no idea what OTS means in this instance, but I prefer to think the lightning zapped it out to sea.
And at some point we may have to just say some of the readings are fine. The MADIS QC jumps could also be changes in the processing or new meso stations coming online. I mean we’ve been tossing ASOS sites left and right lately.
It’s hard to compare temps miles away with scattered clouds and good mixing. It’s not like there’s a steady rise and then fall during the day. You can get 2-3F swings per minute with ASOS probes because of the aspiration and the responsiveness. That’s why they get averaged every 5 mins. Maybe it’s a hair high...idk. But I would guess the instrumentation is fine and that it would be a physical change of the land. Like CON dumping rocks around the ASOS.
Good blog post explaining the 5min data vs hourly metar discrepancies.

Anyway...we’re about maxed out up here. Time for fall.
The 5min archived obs have the higher precision with the T groups...so idk. I have to find the data from the server MW is getting them from and see the raw output.
ftp://ftp.ncdc.noaa.gov/pub/data/asos-fivemin/6401-2019/64010KBDL201906.dat
I'll have to dig more. ISU must have them. I just figured MW would have the full precision if it was available. It's be nice if we could get them...I mean it's 2019...not 1999. We're not on dialup with that big of bandwidth concerns anymore.
lol...BDL is legit 100F. The 6hr max has 100F and 38C is either 100 or 101 (37.8C or 38.3C). So there's no guessing game on whether or not they hit 100F when 38C/100.4F rolls in.
Anyway...the 18z 6hr max and mins are in for 18z.
BAF shows a high of 98.6F (37C) on Mesowest. That technically rounds to 99F, but like I said, it could be 98F or 99F. The 6hr max shows "10367" which is +36.7C...so that's a high of 98F so far.
It's all from NOAA's servers. It's kinda weird because our ASOS stations will report obs in whole degrees F. But we stepped away from the surface aviation obs in 1996 to go with the international METAR coding. So those whole F temps get converted to C. They had to add a T group for temp and dew in the remarks section in order to report temp and dew in tenths celcius (so that we can convert back those readings in whole degrees F). It's a lot of bouncing back and forth. Utah/Mesowest is just converting what they get from NOAA. So the METARs and SPECI (special) obs have the T grouping in tenths, but the relatively new supplementary obs do not have the T group and it just comes in as whole degrees C in the body of the ob.
I guess pilots don't care if it's 96F or 97F. 36C is good enough for them.
The 5 min obs (non METAR or SPECIs) come in via whole degrees celcius. That's what Mesowest gets in. So for BOS that's 36C. For BDL and BAF that was 37C. 36C converted to F is 96.8F. But that just means it is either 96F (35.6C) or 97F (36.1C). It's just a communications limitation from NOAA. I wish they'd just send every 5 min ob in tenths celcius and not whole celcius. Then you'd get the accurate reading in whole degrees F.
ot but why? They pulled this 6 day stretch last year for record high mins.
