And it goes with temperatures too... I think of growing up, if ALB hit 90F we said it was 90 degrees today. Our backyard under dense canopy probably maxed out at 85-86F. But we go by the station that's on the Local on the 8's or that you see on the 6pm news when they say "Albany hit 90F today." So when that 6pm news also shows a dew point of 63F that's what you start associating in your head. Like oh, that's what a 90/63 day felt like.... when the backyard was probably 85/68.
To me it doesn't really matter, but just be consistent. Don't be a clown and pick different variables from different observations.
Anyway, some decent mixing today. Can see BDL has hit 91/57 and ORH 84/57 in the 5-min data. Starting to mix out a bit even in some of the PWS.
