A cut-off upper (500mb/30,000 feet) low continues to spin over the Eastern U.S. with a weak surface low that has moved onshore of N. Carolina. No tropical threat since the low has moved inland. Heavy rain will pinwheel onshore of N. Carolina & Virginia through Wed. night.

Meanwhile... a good deal of Saharan dust (6th image below) is over the Central & Eastern Atlantic. Such large dust clouds are quite typical for June & July & is indicative of generally dry mid & upper level air which usually inhibits tropical development. However, I’ve seen tropical systems thrive just outside the dust cloud ... or once away from the dusty atmosphere... so it’s not a “shoe in” that there will be no tropical development just because a lot of dust exists. Other factors have to be considered such as the overall shear values across the Atlantic Basin, general vertical motion values & sea surface temps.

In general at this time ... the Basin looks to remain quiet into next week.
