The latest forecasts for July 4, 2025, indicate a dynamic weather pattern across the United States, with notable regional differences. The eastern United States is experiencing a cooler trend due to a persistent low-pressure area in northern Canada, resulting in below-average temperatures in the East and Southeast, while a high-pressure ridge over the western U.S. brings warmer conditions to the central and northern states and into southern Canada[1]. This pattern could intensify, spreading cooler anomalies further if the pressure systems remain fixed.
For the holiday weekend, well above normal temperatures are expected to shift from the northern Plains through the Northeast. In addition, strong to severe thunderstorms are possible in these regions, along with a potential for excessive rainfall[2]. A cold front may trigger widespread storms in the northern Plains and Southeast, and there is a small chance for a tropical or subtropical depression to develop off the Southeast coast, drifting north to northeast[5]. Thunderstorms could also impact major travel hubs in the Northeast and at Hartsfield-Jackson Atlanta International Airport, potentially causing flight delays.
Rainfall up to 1.5 inches is forecast for parts of Virginia, eastern Maryland, Delaware, southern New Jersey, and the Carolinas[4]. Storms are likely to spark in the Plains and Southeast on the Fourth of July, while ongoing heat and drought will continue to affect the Southwest and central regions[7].
On July 3, 2025, notable city temperatures included 87°F in Manhattan and New York, 91°F in Philadelphia and Washington, 92°F in Houston, 94°F in Phoenix, and 76°F in Los Angeles, demonstrating the warmth gripping much of the country[8].
