Repeating downpours will continue the risk of flash and urban flooding around New York City and in parts of New Jersey, New York state, Connecticut and Pennsylvania into Thursday.

Bands of heavy rain and thunderstorms will spiral around a slow-moving, land-based storm over the mid-Atlantic.

It is the same storm which brought record May snowfall to parts of the Plains last week and flooding over the past weekend to portions of the Midwest and South.

The rain bands will shift around with time and breaks of sunshine are possible in between. The storm can produce a couple of inches of rain locally over a several-hour period, which is more than enough to cause flooding problems and travel delays. This was the case around New York City on Wednesday, where over three inches of rain fell in a relatively short amount of time.

The storm responsible for the downpours is slowly drifting northeastward, shifting the focus for heavier downpours into southern New England. This includes Boston, Mass., Hartford, Conn. and Providence, R.I. Even so, a few heavier showers and thunderstorms will still linger across the mid-Atlantic, where it will not take much rain to cause additional flooding in areas that saw heavy rain on Wednesday.

Motorists are reminded not to drive through flooded roadways.

It is possible that a few of the thunderstorms might cause lightning strikes to cluster in a small area. The storms also bring the risk of highly localized gusty winds and small hail.

As the storm system finally pulls away on Friday, the showers will move away. However, a cold front approaching from the west will bring the risk for showers and thunderstorms from late Friday into Saturday.
