AccuWeather meteorologists say parts of the Interstate 95 corridor will be at risk for heavy rain and damaging thunderstorms that could trigger severe travel delays before less humid air settles later in the week.
By Thursday night, thunderstorms will break out within an area of warm, moist air and an approaching cold front from parts of central Appalachia to the mid-Atlantic.
In early July, a security software glitch affected some computer systems around the world, and some airlines are trying to catch up. As of mid-week, thousands of flights were still delayed or canceled.
The weather may not be helping. Thunderstorms will cause ground stops as they pass through airports, causing more delays and possibly some flight cancellations at major hubs in the Northeastern United States.
Thunderstorms don't have to be severe to cause travel delays.
A sudden appearance of thunderstorms will extend from eastern New England into the mid- and lower-Atlantic into Thursday night. Scattered thunderstorms are also possible across the central Appalachians.

The major metropolitan areas of Washington, D.C., and Baltimore are currently in an area where thunderstorms can be more severe than normal, with frequent lightning, damaging wind gusts and heavy downpours enough to cause flash flooding.
The risk for showers and thunderstorms will be significantly reduced as moist air moves from the Great Lakes region into parts of the Ohio Valley Thursday night and into New England and the mid-Atlantic coast on Friday. Most of these areas will be rainless for several days.
A blast of dry air with no thunderstorm activity could push southward into parts of the Carolinas this weekend. When this happens, the moisture return will return to the Midwest and random shower and thunderstorm activity will spread northeastward into the region by Sunday.
