They strike me as more marine coastal plain influenced? I’ll have to look closer on a map. I’d assume given the fluidity of the atmosphere there can sometimes be separation between like EMA inside of 495 and outside? Like how FIT is drier sort of removed a bit from the immediate coastal plain? Just spitballing.
Edit: Yeah I could see that air getting to ASH too looking on a map. I saw CON/MHT low 70s and assumed ASH was similar but it is quite a bit further S. Looks like ASH and LWM at 75F now. I dunno, 78F seemed a bit high but wondering why they had 4-5sm visibility haze with those high dews too?
