– Numerous thunderstorms are expected to develop later this
afternoon and continue through late this evening ahead of an
advancing backdoor front moving in from the northeast, as
well as along terrain features to the west. As these
boundaries collide, slow-moving/training thunderstorms are
possible. Particularly concerned about this occurring over
the I-95 corridor. Rainfall amounts of 1 to 2 are possible,
with isolated amounts up to 4 inches possible. This could
occur over a short period of time, potentially resulting in
flash flooding.
