That happens quite a bit. I think mets tend to underestimate those pre-frontal airmasses a lot. I was thinking today could be mid 90s easily with a good launching pad and warm 850s. Only question, was clouds.
SE MA has a decent shot with the most heating I think. Not sure coverage is widespread though. My yard is complete toast after coming back from NH. We burnt/dead.
That lower 30mb averaged dewpoint product from the NAM on the college of DuPage site is pretty good. That usually isn’t as noisy like those surface products. I’ve found it useful.
