Discussion

Waves of low pressure are riding along a frontal boundary zone that is slowly working its way through our area. As a result, in the transition to a cooler weather pattern, showers and thunderstorms will continue into Tuesday and some of the rain will be heavy at times with possible flash flooding. Most locations along the I-95 corridor from DC-to-Philly-to-NYC will see an additional 1.50 to 3.00 inches of rainfall in the next 24 hours or so on top of last night's soaking rains with localized amounts of 4+ inches possible. The second half of the work week will feature some improvement and pretty comfortable temperatures, but a shower or thunderstorm cannot be ruled on any day between Wednesday and Friday.
