Odds of tropical development have decreased for an area to watch off the Southeast Coast but could still deliver a very brief round of showers to parts of the region on July 4, even if it never becomes tropical.

A low-pressure system – technically called a frontal wave – has formed on schedule along the cold front that stalled offshore of the Carolinas. You see it in the satellite picture as a bulge along the front. There’s clearly some circulation with the system.

The upper-level winds are forecast to be marginally conducive for the system to develop into a tropical depression or low-end tropical storm over the next day or two, but that process normally takes time, so the odds are very low it can complete that transition in the short window that it has. The National Hurricane Center is drawing a small zone where that development could take place.

The heat dome high-pressure system moving toward the Northeast U.S. will push the system south and then west toward the coast, but simultaneously the upper-level winds are forecast to become more hostile. No significant effect on land looks likely. In addition, dry air from the heat dome should snuff the system out.
Will keep an eye on it, but nothing much is expected.
