Severe thunderstorms are not forecast on Sunday.

...Synopsis and Discussion...
Surface high pressure will remain dominant across a large majority
of the central/eastern CONUS on Sunday while slowly shifting
eastward. A positively tilted upper trough/low is forecast to
continue moving across the East Coast and Canadian Maritime
provinces. Rich low-level moisture will remain confined to parts of
the FL Peninsula and the Keys through the period. This region will
be located well south of any appreciable large-scale ascent
attendant to the primary upper trough. But, multiple low-amplitude
perturbations embedded within the mid-level southwesterly flow may
encourage isolated convective development Sunday afternoon/evening
over portions of the FL Peninsula and the Keys. With both weak
instability and modest deep-layer shear forecast, severe
thunderstorms are not expected.
