AWOS is pretty bad…especially when Tds start getting up near 70°. Then it seems like they start going up 2° for every 1° reality as they get oversaturated. It gets easy to pick out the ASOS and AWOS stations in IA when they get one of their big summer corn field dewpoint pooling events. ASOS ends up 25-27C and then AWOS is in that 31-32C area. It’s funny seeing 92/89 obs in the afternoon. I remember that JFK day and that it was a high dew day overall. Lots of 77-79 readings and spotty 80+ in the late afternoon down the coast of NJ/DE. JFK was in line with 77-78 most of the day and then had a couple of hours get into the low 80s…82 and 84 on the hourlies IIRC. The temp went down briefly before a slight rebound before evening. There were some TCu around too with the breezy S flow off the water. Maybe a little evap cooling putting a little extra moisture in the air? Not sure. But I’ve seen spikes like that from manned stations pre-ASOS days too with temp recovery after showers/storms.

Refreshed…it’s all the sites mesowest has. ASOS includes the 5 min data. https://www.weather.gov/wrh/hazards?&zoom=9&scroll_zoom=false¢er=43.329173667843904,-71.68579101562501&boundaries=false,false,false,false,false,false,false,false,false,false,false,false,false&tab=observation&obs=true&obs_type=air_temp&obs_popup=false&obs_density=10&obs_provider=ALL
