I don't usually start summertime weather threads (apart from tropical systems), but people seem to be interested in the last few, so why not. Anyway, there's a chance of some severe t-storms this afternoon/evening from the approaching cold front with heavy rains (1/2-1") and possibly damaging winds. Then, overnight, more storms are likely with another low pressure system, with the main threat being heavy rains (1-2" more possible), which, given saturated ground, could mean moderate to even significant urban and small stream flooding in many locations. A flood watch is up for the entire Philly-NJ-NYC region.
Showers and thunderstorms are forecast to bring periods of heavy
rain to our region from Monday afternoon into early Tuesday
morning. Rainfall totals of 1 to 2 inches are expected to be
common, with local amounts up to 3 to 4 inches possible. This
could lead to flash flooding.
