WTF. I don't think I realized that. But even so, nobody else around them had that jump. I'm sorry, but downtown BOS is not cooler than Logan on a stout E wind in late June.
Yeah I would expect to see some change. It's interesting. Usually if they overachieve on temps with a seabreeze it's an ESE wind which IIRC allows more land to be heated before reaching ASOS. But this one is peculiar.
