The trough still has to swing through, but yeah…not looking promising for accums.

I live in reality…not ACATT

3k tries to get Ditty his inch. 69.9” final?

Kidding aside. For the last decade plus, almost every met in here has called out ASOS/AWOS sites when they are starting to run out of line. We overanalyze temps and dews in here daily so we notice when a site starts to report data that is out of place with the norm. I think we have personally contributed to some of these sites getting fixed earlier than they would’ve otherwise been. I have mentioned many times about how ASOS is very responsive and that they had to go with 5 min running means to better mimic the slower response of liquid thermometers. We’ve all mentioned how it’s difficult to thread all of the site’s records with changes in instrumentation, shielding, and siting. It is what it is. But this was just about throwing “UHI” out there because of heat records when every site out there in tumbleweedville is breaking records by 10°F.

Just take your mouth off of vortex’s before you do it. TIA

We pray. But I want to see it inside d5 again before I believe it. Seeing BN heights in New Foundland is giving me PTSD.

Lol

Sausage fest here. Turkey sausage.

Anyway…enough about that. 32.4° with L- Pack is around 2”

I don’t even think we disagree? The instrumentation is accurate when sited and functioning properly and maintained. Unfortunately it’s a struggle to accomplish those things sometimes. Those Vaisala sensors have accuracy greater than 0.1C, but it doesn’t mean a lot if your siting doesn’t accurately represent the 2m temp. But we’ve called out bad ASOS data here a lot…CON, BOS, ORH, BDL, DAW…they’ve all had issues time to time. It’s usually easy to pick out the error on MADIS charts because most of them have a step change.

PHNL was a joke from the get go. The siting was pure sand. Lots of manned obs were trash too. MHT ran too warm for years before ASOS. Lots of bad COOP data too. I think CON was on the side of a brick building in the 1800s. Wherever you look you can find bad obs in different eras. The ASOS temp is very accurate, but like any readings, it’s only as good as its siting and maintenance.

Well I actually think ASOS is pretty good. The bigger issues in my mind are siting and a lack up upkeep in sensor maintenance. GYX had issues at CON years ago because airport maintenance decided to put dark mulch around the ASOS so they didn’t have to mow anymore. BDL just had an issue fixed last year that was causing them to run a solid 2F too warm. But I don’t have an issue with digital thermometers and fan aspiration. And I seem to recall someone telling me once that they had wanted to have automation take over at the Visitor Center, but the digital temps consistently ran cooler than the max/min in the Stevenson screen so it never happened. The same thing happened at Central Park when that poor excuse for an ASOS replaced the COOP.

They’re shattering records in areas of sparse population. It’s simply a record breaking airmass.
