A Level 2 out of 5 severe weather risk is in place from New York City to Pittsburgh, but the exact timing of the storms remains uncertain.

"Showers and thunderstorms lingering into Wednesday night could leave behind cloud cover and rain-cooled air, limiting instability across parts of the Ohio Valley and Mid-Atlantic," the FOX Forecast Center said.

Despite this, forecasters predict there to be enough moisture and instability to surge to the north by midday Thursday.

The moisture, which is driven by an unusually powerful jet stream and a fast-moving cold front, will advance from the western U.S., triggering widespread thunderstorms.

According to the FOX Forecast Center, cooling air will allow for discrete storms capable of producing large and damaging hail.

WHAT IS A COLD FRONT?

Locations facing the greatest risk of these storms on Thursday include Washington, D.C., New York City and Philadelphia.

As the persistent heavy rainfall continues, it will fuel a Level 2 out of 4 flash flood risk across portions of the Ohio Valley, West Virginia and Western Pennsylvania.
