US East Coast weather: humidity and thunderstorms expected

A humid air mass is moving across the eastern United States, bringing a heightened risk of thunderstorms and heavy rain in several regions. In New Jersey, forecasters anticipate a four‑day period of unsettled weather with spotty showers early in the week and a marginal risk of severe thunderstorms on Monday, rising to a slight risk on Tuesday. Models project over an inch of rain, raising flooding concerns.

The Alabama Gulf Coast is facing hot, humid conditions with the possibility of isolated showers, while southern West Virginia may see damaging wind gusts and heavy rainfall from a complex of storms early Tuesday, though tornado and hail threats remain low. Boston and surrounding Massachusetts areas will enjoy a final stretch of sunny, cooler weather before a low‑pressure system brings showers and potential flooding from Wednesday through Thursday.

Meteorologists warn that the combined moisture and unstable atmosphere could produce localized flash‑flooding and ponding on roadways, especially where rain totals exceed an inch. Residents are advised to stay informed of updates, watch for rip‑current warnings on the Cape, and prepare for possible travel disruptions.
