This looks like one of those MU CAPE bombs that get the S coast of New England and Cape Cod. S/W approaches near dawn with cooler temps aloft. Could be a good light show around dawn in those parts.
Next week will be hot and then after maybe a little cooler and drier for a time(probably still AN). But I'm sure they'll be plenty of 88-93 and high humidity in August.
Kind of a funny cool eddy in MA Bay. Boston Buoy at 61 and Stellwagen Bay 56. I don't think I've seen that so late in the season. Meanwhile off the south coast it's in the 70s or close to it.
