Things, and no context.

But weirdee, I know the context of that. It's so simple. The far southeast is usually moist, and with the added moisture of the southwestern wind from the mid-latitude cyclone (located north of where the picture cuts off) drawing in Gulf air, the dewpoints should reach upper sixties at least. However, the warm sector is soon departing, as the cold front from the tail of the MLC is approaching. With the high humidities creating easily unstable profiles with levels of free convection not that high above the ground, the overall profile is likely to erupt into thunderstorms (possibly severe; would need to see the shear to be able to predict that) with any source of lifting. And what better source of lift is there than the normally strong cold front? That, combined with the extremely favourable environment that is existing, means that those who live in that area should definitely expect the humidity to give way to thunderstorms within the next day or so. Though given our weather here, it's likely already passed for the northern areas of that group of states.
