Incoming rounds of heavy rain and thunderstorms trigger midweek flash flood threat across the East Coast

By Thursday afternoon, showers and thunderstorms will develop across the Southeast and into the Northeast, with rainfall rates of up to 2.5 inches per hour in some of the worst areas.

Unpleasant news for millions of Americans across the East Coast, as rounds of heavy rain and thunderstorms are expected to dampen the chance of spending time outdoors this week.

Thankfully, there will be a brief break in the wet weather on Tuesday and Wednesday before storms resume for the latter part of the week.

Forecasters are monitoring a cold front expected to bring heavy rain and flooding across the Midwest through Wednesday, before shifting east.

WHAT IS A COLD FRONT?

As this occurs, high pressure positioned off the East Coast will produce a flow that will attract moisture from the Atlantic Ocean.

By Thursday afternoon, showers and thunderstorms will develop across the Southeast and into the Northeast, with rainfall rates of up to 2.5 inches per hour in some of the worst areas, according to the FOX Forecast Center.

As many areas have already received heavy rain, the already saturated soil won’t be able to absorb the persistent precipitation, which will likely result in flash flooding.

This comes as a Level 1 out of 4 flash flood threat is in effect across portions of the Northeast and Southeast Thursday through Saturday.

Through the weekend, the wet weather will continue, with rainfall totals ranging from 0.5 to 1 inch across the Northeast and Mid-Atlantic regions, accompanied by repeated thunderstorms.

Significant flash flooding will be the primary concern through Saturday, as many areas have already exceeded average rainfall totals this summer.

Locations such as Bridgeport, Connecticut, are running more than seven inches above average.
