After overnight random rains poured 2-plus inches on parts of the region, a fresh round of thunderstorms is setting off flash flood warnings and watches.

The National Weather Service has a warning posted until 5:45 p.m. for parts of Bucks, Chester, and Montgomery Counties where a nasty line of storms is bearing down in advance of a cold front.

Weather service hydrologist Ray Kruzdlo advises that to up to 3 inches an hour could fall in those storms.

A flash-flood watch remains for Philadelphia and all seven of its neighboring counties until 2 a.m.

Unlike the capricious downpours earlier this week, this time around gusty winds up to 40 m.p.h. and lightning are possible.
