The 5 mins are fine. But it’s like the :54 obs are going out as local time instead of GMT. So when 5:54am goes out it’s trying to send 5:54z in the database. 955z ob was 70° but the :54 ob was 72°. If I’m right on this the 6:54am ob will be about 71°.

So the BOS thing is weird. It seems like there’s a 4hr lag right now with the time stamp for the hourly METAR at :54 past the hour. IOW, the ob coming up soon for 5:54am (954z) will be the temperature that it should have been for 554z. That’s why the :54 obs seemed to spike high last night. I have a hunch that they will spike low this morning unless they fix the timestamp issue. lol

63.6/58

78.5/68 A little stuffy here, but not bad.

I'd have to look at the numbers, but it does feel like when we push 100F in late June it tends to return at some point in the summer. Maybe not 100s, but at least U90s.

I'll give them a chance to fix everything, but ASOS is becoming a joke for climate data. Just throw a friggin Davis out there for cheap and with the money you save hire a worker to sit by it all day in case something fails.

My point is the 5 minute obs look correct and the corrected METARs look wrong...just going by temps surrounding the station.

Ha ha ha somehow they have a min of 51F in there.

At least the afternoon CLI report has a high of only 93F.

Are they augmenting the regular hourlies? The 5 min obs look more legit. Why does observing at the climo sites always have to be a shitshow?

WTF are they doing at BOS with the hourly METARs (:54 past) versus the 5 min obs? https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=KBOS&time=GMT

Looking at the 1-min data now...RDU looks fine https://mesonet.agron.iastate.edu/cgi-bin/request/asos1min.py?station=RDU&tz=UTC&year1=2025&month1=6&day1=22&hour1=0&minute1=0&year2=2025&month2=6&day2=22&hour2=23&minute2=59&vars=tmpf&sample=1min&what=view&delim=comma&gis=no No crazy spikes.

So Allan sees 93 97 93 on his site.

I mean we're talking 100F vs 99F I just picked a random hot month...July 2011. HFD 87.9 BDL 87.3 Both hit 103F on the hottest day.

HFD and BDL are both 80.5F for the avg high in June through yesterday.

It's fine. It's back to what it used to be.

Bye BOS https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=KBOS&time=GMT

@CoastalWx Got a date of a good screen door slammer at BOS within the last 2 years?

BOX fixed the sensor. It was running a clear 3F too warm. It's been pretty good lately.

Yeah the sensor is malfunctioning. It just did it again.

@CoastalWx 7/22/2011 for BOS. 104F at 1949z https://mesonet.agron.iastate.edu/cgi-bin/request/asos1min.py?station=BOS&tz=UTC&year1=2011&month1=7&day1=22&hour1=0&minute1=0&year2=2011&month2=7&day2=22&hour2=23&minute2=0&vars=tmpf&sample=1min&what=view&delim=comma&gis=no

Looks like Iowa St gets the 1-min data in within 2 days so we'll see.

I know it was 5 mins in 2011 because BOS had a raw minute of 104F in there surrounded by 103F and the high for the day went in as 103F.

I swear I remember it being 5 min unless it was changed.

@OceanStWx Can you get early access to the raw 1-min data?

However, the 5 min avg never got above 95F (6hr max at 1754z was 95F). And the temp spiked and triggered a SPECI at 1743z when it jumped from 86F to 93F in 3 minutes. So there must have been a few random big spikes thrown in there with normal 80-82F obs unless I have no clue what I'm talking about anymore.
