Showers, storms to advance into I-95 corridor and threaten flooding

Isolated storms could bring road disruptions due to flooding, and frustration to travelers.


AccuWeather Global Weather Center – January 2, 2020 – As heat and humidity hold on in the eastern United States, a slow-moving swath of drenching showers and thunderstorms will advance from the Appalachians to the Eastern Seaboard and eventually stall as the week progresses.

While widespread severe weather is not anticipated this week, isolated severe storms are anticipated.

A storm hit the Chattanooga Metropolitan Airport in Chattanooga, Tennessee, causing damage to the roof of the terminal. Despite the damage, the airport remained open, according to WRCB-TV. A wind gust of 56 mph was clocked at the airport's weather station as the storm whipped through.

On Wednesday afternoon, over 330 flights were delayed at the Boston Logan International Airport as gusty thunderstorms moved through the city.

The storms can pack enough rainfall to lead to localized incidents of urban and small stream flooding.

As the storms approach heavily populated areas, travel disruptions will increase with the potential for some roads to be blocked by rapidly rising water.

During Wednesday afternoon, rain fell at the rate of 2 inches per hour in the swath from Philadelphia to Trenton, New Jersey.

Airline delays are likely as the storms approach and pass over airports.

A small number of the storms can be robust enough to bring strong wind gusts which can break tree limbs and cause sporadic power outages. A few incidents of small hail can occur as well.
