Severe storm ingredients fuel possibility of tropical development late next week along Gulf of America

The FOX Forecast Center is eying possible development of tropical storms in the coming weeks for areas along the Gulf Coast and the Bay of Campeche.

By next week, forecasters are monitoring a large-scale weather pattern featuring an upper-level low, with a split in the mid-level ridge and troughing extending far into the southern U.S.

According to the National Weather Service, a trough is a lengthened area of relatively low atmospheric pressure and is usually not associated with a closed circulation.

This trough introduces a weakness to the ridge that spans across the Gulf. At the same time, the ridging will extend into the Caribbean and establish a strong southerly flow from the Eastern Pacific and into the Gulf of America.

This could bring tropical moisture to northern portions of the country, potentially supporting severe storm development.

Forecasters are also seeing signals that a broad area of spin across the Central U.S. could return into next week, which could aid in tropical storm development.

"This is typically referred to as the Central American Gyre and is a sprawling area of low pressure that can produce locally heavy rain and aid in the formation of tropical cyclones," the FOX Forecast Center said.

This is most typical in late spring and early fall. Because of this, it does not guarantee tropical development.

"The greater interest stems from the upcoming hurricane tracking near the East Pacific coast and what may follow behind it, the FOX Forecast Center said.

As the ridge builds, the atmospheric flow could help draw a substantial plume of tropical moisture northward.

As a result, above-average rainfall is becoming increasingly more likely across portions of the Gulf Coast.

Given this upper-level pattern, energy from the Eastern Pacific could cross into the Gulf, further enhancing moisture in the region.

Forecast models expect this development to form into late next week, but uncertainty remains about whether severe storms will develop.
